https://en.wikipedia.org/wiki/Electronic%20quantum%20holography | Electronic quantum holography (also known as quantum holographic data storage) is an information storage technology which can encode and read out data at unprecedented density storing as much as 35 bits per electron.
Research
In 2009, Stanford University's Department of Physics set a new world record for the smallest writing using a scanning tunneling microscope and electron waves to write the initials "SU" at 0.3 nanometers, surpassing the previous record set by IBM in 1989 using xenon atoms. This achievement also set a record for the density of information. Before this technology was invented the density of information had not exceeded one bit per atom. Researchers of electronic quantum holography however were able to push the limit to 35 bits per electron or 20 bits nm−2.
Technology
A copper chip is placed in a microscope and cleaned. Carbon monoxide molecules are then placed on the surface and moved around. When the electrons in copper interact with the carbon monoxide molecules, they create interference patterns that create an electronic quantum hologram. This hologram can be read like a stack of pages in a book, and can contain multiple images at different wavelengths.

https://en.wikipedia.org/wiki/Cloud%20%28operating%20system%29 | Cloud was a browser-based operating system created by Good OS LLC, a Los Angelesbased corporation. The company initially launched a Linux distribution called gOS which is heavily based on Ubuntu, now in its third incarnation.
Overview
The Cloud was a simplified operating system that ran just a web browser, providing access to a variety of web-based applications that allowed the user to perform many simple tasks without booting a full-scale operating system. Because of its simplicity, Cloud could boot in just a few seconds. The operating system is designed for Netbooks, Mobile Internet Devices, and PCs that are mainly used to browse the Internet. From Cloud the user can quickly boot into the main OS, because Cloud continues booting the main OS in the background.
Combining a browser with a basic operating system allows the use of cloud computing, in which applications and data "live and run" on the Internet instead of the hard drive.
Cloud can be installed and used together with other operating systems, or act as a standalone operating system. When used as a standalone operating system, hardware requirements are relatively low.
In 2009, Cloud was only officially available built into the GIGABYTE M912 Touch Screen Netbook.
Early reviews compared the operating system's user interface to OS X and noted the similarity of its browser to Google Chrome, although it is actually based on a modified Mozilla Firefox browser

https://en.wikipedia.org/wiki/PhyloXML | PhyloXML is an XML language for the analysis, exchange, and storage of phylogenetic trees (or networks) and associated data. The structure of phyloXML is described by XML Schema Definition (XSD) language.
A shortcoming of current formats for describing phylogenetic trees (such as Nexus and Newick/New Hampshire) is a lack of a standardized means to annotate tree nodes and branches with distinct data fields (which in the case of a basic species tree might be: species names, branch lengths, and possibly multiple support values). Data storage and exchange is even more cumbersome in studies in which trees are the result of a reconciliation of some kind:
gene-function studies (requires annotation of nodes with taxonomic information as well as gene names, and possibly gene-duplication data)
evolution of host-parasite interactions (requires annotation of tree nodes with taxonomic information for both host and parasite)
phylogeographic studies (requires annotation of tree nodes with taxonomic and geographic information)
To alleviate this, a variety of ad-hoc, special purpose formats have come into use (such as the NHX format, which focuses on the needs of gene-function and phylogenomic studies).
A well defined XML format addresses these problems in a general and extensible manner and allows for interoperability between specialized and general purpose software.
An example of a program for visualizing phyloXML is Archaeopteryx.

https://en.wikipedia.org/wiki/History%20of%20Python | The programming language Python was conceived in the late 1980s, and its implementation was started in December 1989 by Guido van Rossum at CWI in the Netherlands as a successor to ABC capable of exception handling and interfacing with the Amoeba operating system. Van Rossum is Python's principal author, and his continuing central role in deciding the direction of Python is reflected in the title given to him by the Python community, Benevolent Dictator for Life (BDFL). (However, Van Rossum stepped down as leader on July 12, 2018.). Python was named after the BBC TV show Monty Python's Flying Circus.
Python 2.0 was released on October 16, 2000, with many major new features, including a cycle-detecting garbage collector (in addition to reference counting) for memory management and support for Unicode. However, the most important change was to the development process itself, with a shift to a more transparent and community-backed process.
Python 3.0, a major, backwards-incompatible release, was released on December 3, 2008 after a long period of testing. Many of its major features have also been backported to the backwards-compatible, though now-unsupported, Python 2.6 and 2.7.
Early history
In February 1991, Van Rossum published the code (labeled version 0.9.0) to alt.sources. Already present at this stage in development were classes with inheritance, exception handling, functions, and the core datatypes of , , and so on. Also in this initial release was a module system borrowed from Modula-3; Van Rossum describes the module as "one of Python's major programming units". Python's exception model also resembles Modula-3's, with the addition of an clause. In 1994 comp.lang.python, the primary discussion forum for Python, was formed, marking a milestone in the growth of Python's userbase.
Version 1
Python reached version 1.0 in January 1994. The major new features included in this release were the functional programming tools lambda, map, filter and reduce. Van Rossum stated that "Python acquired lambda, reduce(), filter() and map(), courtesy of a Lisp hacker who missed them and submitted working patches".
The last version released while Van Rossum was at CWI was Python 1.2. In 1995, Van Rossum continued his work on Python at the Corporation for National Research Initiatives (CNRI) in Reston, Virginia from where he released several versions.
By version 1.4, Python had acquired several new features. Notable among these are the Modula-3 inspired keyword arguments (which are also similar to Common Lisp's keyword arguments) and built-in support for complex numbers. Also included is a basic form of data hiding by name mangling, though this is easily bypassed.
During Van Rossum's stay at CNRI, he launched the Computer Programming for Everybody (CP4E) initiative, intending to make programming more accessible to more people, with a basic "literacy" in programming languages, similar to the basic English literacy and mathematics skills required by mos |
https://en.wikipedia.org/wiki/Harry%27s%20Practice | Harry's Practice was an Australian lifestyle television program that was broadcast on the Seven Network between 2 December 1997 and 2003. In New Zealand, the show was broadcast on TV ONE.
The show was hosted by veterinarian Harry Cooper, who provided advice for pet care. The show also featured Katrina Warren and Chris Brown as presenters. Cooper currently is involved with Better Homes and Gardens, a television program, in which he performs similar show segments as to that previously seen on Harry's Practice.

https://en.wikipedia.org/wiki/Mike%20Grella | Michele Grella (born January 23, 1987) is an American former professional soccer player who played as a forward and winger, who is currently a soccer analyst for CBS Sports Network and Paramount+.
Club career
Youth and amateur
Grella was born in Glen Cove, New York and had a highly successful youth career playing as a striker. He was a 2003 and 2004 Parade Magazine High School All American soccer player and the 2004 NSCAA National High School Player of the Year for the Glen Cove Big Red. He led his club team, the Albertson Red Storm, to both the 2003 and 2004 USYSA National Championships and the Red Storm Academy to the 2004 Super Y-League Championship. Grella played college soccer for Duke University where he was a 2008 first team All American.
During the 2007 collegiate offseason, he played for the Long Island Rough Riders in the fourth division USL Premier Development League for coach Mike Mackney. In 2008, he played five more games for Long Island before switching to play for the Cary RailHawks U23's mid-season.
Leeds United
2008–09 season
In February 2009, he was drafted in the third round (34th overall) of the 2009 MLS SuperDraft by Toronto FC. However, Grella decided against signing for the Canadian club, and instead tried his luck at playing in Europe. Grella went on trial with Leeds United in January 2009, and scored a hat-trick for the club's reserves on the 21st of that month against Barnsley FC.
He also scored a goal in a behind closed doors game, with news of a permanent deal pending. He signed a full-time contract for Leeds United on transfer deadline day, 2 February 2009, until the end of the 2009–10 season.
He made his Leeds debut on 14 February 2009, after coming on as a 74th minute substitute for Lee Trundle in a 1–0 defeat to Huddersfield Town. His first season in professional football was mainly spent making short cameos as a substitute during Leeds fight for promotion. He came on late in Leeds' playoff semi final against Millwall but was unable to grab a goal during his first team appearances for Leeds.
2009–10 season
Grella scored his first senior goal for Leeds in a pre-season friendly against Burnley. On 10 August 2009 he was voted Man Of The Match in a League Cup match against Darlington although he didn't score. He signed a new long-term contract with Leeds.
Grella had to wait just over seven months for his first league start. Replacing the injured Jermaine Beckford in the starting line up for the visit of Stockport County to Elland Road on 5 September 2009, it took him just eight minutes to score his first league goal, curling in an opportunistic effort from the edge of the penalty area.
Grella scored for Leeds after coming on as a late substitute in the 2–0 FA Cup win against Oldham. He repeated this FA Cup goalscoring form on 8 December 2009 in the FA Cup replay against Kettering Town, coming on as a substitute during the second period of extra time. Grella's introduction changed the pace of the game (which |
https://en.wikipedia.org/wiki/John%20Krogstie | John Krogstie (born 23 May 1967) is a Norwegian computer scientist, professor in information systems at the Norwegian University of Science and Technology (NTNU) in Trondheim, Norway, and an expert in the field of enterprise modelling.
Biography
John Krogstie received a MSc in 1991 and a PhD in 1995 both in information systems from the Norwegian University of Science and Technology.
From 1991 to 2000 he was employed as a manager in Accenture. In 2000-2005 he was a senior researcher in SINTEF. He is a professor in information systems at NTNU in Trondheim, Norway.
John Krogstie is the Norwegian representative for IFIP TC8 and was Chair (2010–2015) of IFIP WG 8.1 on information systems design and evaluation.
Work
Krogstie's research interests include information systems, conceptual modeling, mobile information systems, eGovernment and enterprise modelling.
The SEQUAL framework
The SEQUAL framework is a reference model for evaluating the quality of models, the semiotic quality framework (SEQUAL) developed by John Krogstie. The SEQUAL framework is grounded in semiotics, particularly the semiotic theory of Charles W. Morris. It builds on semiotic theory and defines several quality aspects based on relationships between a model, a body of knowledge, a domain, a modeling language, and the activities of learning, taking action, and modeling.
Its usefulness was confirmed in a 2002 experiment.
The basic idea behind the SEQUAL framework is, that conceptual models can be considered as sets of
statements in a language, and therefore can be evaluated in semiotic/linguistic terms. A first semiotic framework for evaluating conceptual models was originally proposed by Lindland et al. in the 1994 article "Understanding quality in conceptual modeling". In its initial version, it considered three quality levels:
syntactic,
semantic, and
pragmatic quality
The framework was later extended, and called the SEQUAL framework by Krogstie et al. in the 1995 article "Defining quality aspects for conceptual models". In the 2002 article "Quality of interactive models" Krogstie & Jørgensen extended the initial framework adding
more levels of Stamper’s semiotic ladder.
Perspectives to Process Modeling, 2013
In the 2013 article Perspectives to Process Modeling a review is presented of business process modeling; first describing the main approaches of process modeling which are then classified according to the main modeling perspective being used with modeling perspectives namely the: behavioral, functional, structural, goal-oriented, object-oriented, language action, organizational and geographical.

https://en.wikipedia.org/wiki/Aakash%20%28tablet%29 | Aakash a.k.a. Ubislate 7+, is an Android-based tablet computer promoted by the Government of India as part of an initiative to link 25,000 colleges and 400 universities in an e-learning program. It was produced by the British-Canadian company DataWind, and manufactured by the company, at a production center in Hyderabad. The tablet was officially launched as the Aakash in New Delhi on 5 October 2011. The Indian Ministry of Human Resource Development announced an upgraded second-generation model called Aakash 2 in April 2012.
The Aakash was a low-cost tablet computer with a 7-inch touch screen, ARM 11 processor, and 256 MB RAM running under the Android 2.2 operating system. It had two USB ports and delivered high definition (HD) quality video. For applications; the Aakash had access to Getjar, an independent market, rather than the Android Market.
Originally projected as a "$35 laptop", the device was to be sold to the Government of India and distributed to university students – initially at US$50 until further orders are received and projected eventually to achieve the target $35 price. A commercial version of Aakash was marketed as UbiSlate 7+ at a price of $60. The Aakash 2, code named UbiSlate 7C, was released on 11 November 2012.
Etymology
The device was initially called the Sakshat tablet, later changed to Aakash, which is derived from the Sanskrit word Akasha (Devanagari आकाश) with several related meanings such as empty space and outer space. The word in Hindi means "sky".
History
The aspiration to create a "Made in India" computer was first reflected in a prototype "Simputer" that was produced in small numbers. Bangalore-based CPSU, Bharat Electronics Ltd manufactured around 5,000 Simputers for Indian customers from 2002 to 2007. In 2011, Kapil Sibal announced an anticipated low-cost computing device to compete with the One Laptop per Child (OLPC) initiative, though intended for urban college students rather than the OLPC's rural, underprivileged students.
A year later, the MHRD announced that the low-cost computer would be launched in six weeks. Nine weeks later, the MHRD showcased a tablet named "Aakash", not nearly what had been projected and at US$60 rather than the projected $35. "NDTV" reported that the new low-cost tablet was considerably less able than the previously shown prototype and was going to cost about twice as much.
While it was once projected as a laptop, the design has evolved into a tablet computer. At the inauguration of the National Mission on Education Program organized by the Union HRD Ministry in 2009, joint secretary N. K. Sinha had said that the computing device is 10 inches (which is around 25.5 cm) long and 5 inches (12.5 cm) wide and priced at around US$30.
India's Human Resource Development Minister, Kapil Sibal, unveiled a prototype on 22 July 2010, which was later given out to 500 college students to collect feedback. The price of the device exhibited was projected at $35 USD, eventually to drop to |

https://en.wikipedia.org/wiki/A.Side%20TV | A.Side TV was a Canadian English language discretionary specialty channel owned by Blue Ant Media. Originally focusing on music and pop culture programming, the channel drifted towards generic true crime and paranormal programming before it wound down operations in mid-January 2023.
History
As AUX (2009-2016)
Originating under the branding, AUX, the channel's origins begin in 2008 when original owners, Glassbox Television, launched both an AUX-branded website and a 2-hour programming block on sister channel BiteTV that focused on music-related programming featuring primarily independent, and new and emerging artists in alternative, hip hop, indie rock, indie pop and other similar genres. Both the website and the programming block launched on November 24, 2008.
In February 2009, AUX participated with CBC Radio 3 and Exclaim! to launch "X3", a new collaborative cross-promotional platform which saw all three outlets create content spotlighting a particular "Artist of the Month". X3 artists of the month have included K'naan, Malajube, Thunderheist, Japandroids, Apostle of Hustle and The Rural Alberta Advantage. The project ceased in 2012.
Glassbox Television received approval by the Canadian Radio-television and Telecommunications Commission (CRTC) to launch AUX as a national English-language category 2 specialty channel on March 6, 2009, describing the channel n regulatory documents as a service "devoted to emerging music and its creation, including programming featuring emerging music and aimed at helping emerging musicians." The channel was launched on October 1, 2009, exclusively on Rogers Cable (in Ontario and New Brunswick, and shortly thereafter in Newfoundland and Labrador). Later, other providers such as Shaw Cable, Shaw Direct, EastLink, and Source Cable launched the channel on their systems, eventually obtaining wide national distribution on most majors television providers in Canada.
In April 2010, the CRTC denied an application by Glassbox to launch a French-language version of AUX, as Astral Media had filed an intervention against the Glassbox application suggesting that the channel would be in competition with the established music video networks MusiquePlus and MusiMax.
On April 11, 2011, it was announced that Blue Ant Media would acquire a controlling interest in Glassbox Television. Blue Ant Media initially acquired a 29.9% stake in the company, with the option to expand their stake up to 75% which would give the company controlling interest. The company would later be purchased outright by Blue Ant Media in the summer of 2012.
On June 4, 2013, AUX launched a high definition feed.
As A.Side
On April 6, 2017, Blue Ant Media, along with Shed Creative Agency, announced that the channel would be rebranded A.Side TV, later confirmed to launch on May 30, 2017. The purpose of the rebrand was to align the channel with the newly formed multi-platform music brand, A.Side, which launched on May 18, 2017, and focuses on general pop mus |
https://en.wikipedia.org/wiki/Manhattan%20mobility%20model | The Manhattan mobility model is a guide which leads the driver of a vehicle on the correct path. It is an urban type of mobility model for vehicular ad-hoc networks (VANET). The Manhattan mobility model uses a "grid road topology. It works optimally where streets are in an organized manner.
In this mobility model, mobile nodes move in horizontal or vertical direction on an urban map. The Manhattan model employs a probabilistic approach in the selection of nodes movements since, at each intersection, a vehicle chooses to keep moving in the same direction. The probability of going straight is 0.5 and taking a left or right is 0.25 each.
The Manhattan model is not suitable for highway systems. Although this model provides flexibility for the nodes to change the direction, it imposes geographic restrictions on node mobility.
Important Characteristics of the Manhattan Mobility model
The mobile node is allowed to move along the grid of horizontal and vertical streets on the map.
At an intersection of a horizontal and a vertical street, the mobile node can turn left, right or go straight with certain probability.
Excepting the above difference, the inter-node and intra-node relationships involved in the Manhattan model are the same as in the Freeway model.

https://en.wikipedia.org/wiki/Indian%20Youth%20Climate%20Network | The Indian Youth Climate Network (IYCN) is a youth organization in India that aims to raise the voice of Indian youth on the global platform, as South Asia is one of the most vulnerable regions affected by climate change and environmental issues. Further, IYCN is motivated by global need in the Indian context to adopt mitigation and adaptation policy measure to combat climate change.
IYCN members work to generate consensus on what role India should play in the global debate of climate change, and how it should address its domestic issues.
Started in 2008, IYCN was registered as an NGO in 2009 and today IYCN has offices in six locations with chapters in the Indian states, having outreach to thousands of youth in colleges, schools, corporations and institutions in India.
IYCN has "informed youth" as its leaders and program members who:
Follow environmental and climate change policies and make recommendations at state, national and international platforms.
Run campaigns aimed at public awareness on climate change impact & causes. In this process, the chapters mobilise and informing thousands of Indian citizens.
Implement projects such as composting and community waste management, rural energy projects, lake clean-ups, and herbal and medicine gardens.
IYCN works at three levels:
As a network of individuals enabling people to come together and work at a grassroots level, to form friendships and support each other.
As a network of partner and supporter groups who bring together their strengths and passion for environment and sustainable development.
As an organisation that runs its own programs/projects as well as participates in and supports programs/campaigns of other organisations.
Chapters
The Indian Youth Climate Network (IYCN) has several chapters across India.

https://en.wikipedia.org/wiki/Process%20architecture | Process architecture is the structural design of general process systems. It applies to fields such as computers (software, hardware, networks, etc.), business processes (enterprise architecture, policy and procedures, logistics, project management, etc.), and any other process system of varying degrees of complexity.
Processes are defined as having inputs, outputs and the energy required to transform inputs to outputs. Use of energy during transformation also implies a passage of time: a process takes real time to perform its associated action. A process also requires space for input/output objects and transforming objects to exist: a process uses real space.
A process system is a specialized system of processes. Processes are composed of processes. Complex processes are made up of several processes that are in turn made up of several processes. This results in an overall structural hierarchy of abstraction. If the process system is studied hierarchically, it is easier to understand and manage; therefore, process architecture requires the ability to consider process systems hierarchically. Graphical modeling of process architectures is considered by dualistic Petri nets. Mathematical consideration of process architectures may be found in CCS and the π-calculus.
The structure of a process system, or its architecture, can be viewed as a dualistic relationship of its infrastructure and suprastructure. The infrastructure describes a process system's component parts and their interactions. The suprastructure considers the super system of which the process system is a part. (Suprastructure should not be confused with superstructure, which is actually part of the infrastructure built for (external) support.) As one traverses the process architecture from one level of abstraction to the next, infrastructure becomes the basis for suprastructure and vice versa as one looks within a system or without.
Requirements for a process system are derived at every hierarchical level. Black-box requirements for a system come from its suprastructure. Customer requirements are black-box requirements near, if not at, the top of a process architecture's hierarchy. White-box requirements, such as engineering rules, programming syntax, etc., come from the process system's infrastructure.
Process systems are a dualistic phenomenon of change/no-change or form/transform and as such, are
well-suited to being modeled by the bipartite Petri nets modeling system and in particular, process-class dualistic Petri nets where processes can be simulated in real time and space and studied hierarchically.

https://en.wikipedia.org/wiki/River%2C%20Estuary%20and%20Coastal%20Observing%20Network | The River, Estuary, and Coastal Observing Network (RECON) is a pioneering waterway observing system founded and maintained by Sanibel-Captiva Conservation Foundation (SCCF) operated by the SCCF's Marine Laboratory at Tarpon Bay.
RECON is funded primarily by private donations to SCCF's Marine Laboratory. Seven fixed locations stream water quality data from in situ Satlantic instrument packages. The sensor array includes a chemical-free nitrate sensor (ISUS), a CTD (conductivity, temperature, and depth) and fluorometer package for depth, turbidity, temperature, dissolved oxygen, salinity, and chlorophyll a fitted with a bleach injection system (WETLabs, Water Quality Monitor), and a CDOM fluorometer. One of the stations also incorporates a Nortek Aquadopp 2-dimensional current profiler sampling at 1 MHz for flow measurements. Data are currently collected hourly and transmitted in near-real time via cellular modems to a dedicated SQL database and can be viewed also in near real-time and plotted at RECON's website.
Extensive field testing by SCCF has led also to several innovative modifications to improve duration and robustness of these instruments. These include a non-toxic exterior anti-fouling paint, copper foil applied to all connectors and cables, and a custom designed support structure to attach to existing pilings. Other enhancements include a user-friendly website designed for scientists, decision-makers and the general public. Information disseminated through the website includes concise definitions of water quality parameters measured and how to interpret trends in water quality at high resolution. To maintain data quality control, water samples are collected to validate instrument settings and readings with traditional wet-chemistry methods. Water samples are analyzed by a state-certified Florida Department of Environmental Protection laboratory in Tallahassee, FL. SCCF plans to maintain the observing systems for the next three years or more, depending on funding.

https://en.wikipedia.org/wiki/Sequoia%20%28supercomputer%29 | IBM Sequoia was a petascale Blue Gene/Q supercomputer constructed by IBM for the National Nuclear Security Administration as part of the Advanced Simulation and Computing Program (ASC). It was delivered to the Lawrence Livermore National Laboratory (LLNL) in 2011 and was fully deployed in June 2012. Sequoia was dismantled in 2020, its last position on the top500.org list was #22 in the November 2019 list.
On June 14, 2012, the TOP500 Project Committee announced that Sequoia replaced the K computer as the world's fastest supercomputer, with a LINPACK performance of 17.17 petaflops, 63% faster than the K computer's 10.51 petaflops, having 123% more cores than the K computer's 705,024 cores. Sequoia is also more energy efficient, as it consumes 7.9 MW, 37% less than the K computer's 12.6 MW.
, Sequoia had dropped to sixth place on the TOP500 ranking, while it was at third position on June 17, 2013, behind Tianhe-2 and Titan. In June 2016, it slipped again, to fourth place on the TOP500 ranking. In June 2017, it slipped again, to fifth place on the TOP500 ranking.
Record-breaking science applications have been run on Sequoia, the first to cross 10 petaflops of sustained performance. The cosmology simulation framework HACC achieved almost 14 petaflops with a 3.6 trillion particle benchmark run, while the Cardioid code, which models the electrophysiology of the human heart, achieved nearly 12 petaflops with a near real-time simulation.
The entire supercomputer runs on Linux, with CNK running on over 98,000 nodes, and Red Hat Enterprise Linux running on 768 I/O nodes that are connected to the Lustre filesystem.
Dawn prototype
IBM built a prototype, called "Dawn", capable of 500 teraflops, using the Blue Gene/P design, to evaluate the Sequoia design. This system was delivered in April 2009 and entered the Top500 list at 9th place in June 2009.
Purpose
Sequoia was used primarily for nuclear weapons simulation, replacing the current Blue Gene/L and ASC Purple supercomputers at Lawrence Livermore National Laboratory. Sequoia was also available for scientific purposes such as astronomy, energy, lattice QCD, study of the human genome, and climate change.
Design
Node architecture
Sequoia was a Blue Gene/Q design, based on previous Blue Gene designs. It consisted of 96 racks containing 98,304 compute nodes, i.e., 1024 per rack. The compute nodes were 16-core A2 processor chips with 16 GB of DDR3 memory each. Thus, the system contained a total of 96·1024·16 = 1,572,864 processor cores with 1.5 PiB memory. It covered an area of about . The compute nodes were interconnected in a 5-dimensional torus topology.
Job scheduler
LLNL used the SLURM job scheduler, also used by the Dawn prototype and China's Tianhe-IA, to manage Sequoia's resources.
Filesystem
LLNL uses Lustre as the parallel filesystem, and has ported ZFS to Linux as the Lustre OSD (Object Storage Device) to take advantage of the performance and advanced features of the filesystem.

https://en.wikipedia.org/wiki/Pricing%20science | Pricing science is the application of social and business science methods to the problem of setting prices. Methods include economic modeling, statistics, econometrics, mathematical programming. This discipline had its origins in the development of yield management in the airline industry in the 1980s, and has since spread to many other sectors and pricing contexts, including yield management in other travel industry sectors, media, retail, manufacturing and distribution.
Pricing science work is effectuated in a variety of ways, from strategic advice on pricing on defining segments for which pricing strategies may vary, to enterprise-class software applications, integrated into price quoting and selling processes.
History
Pricing science has its roots in the development of yield management programs developed by the airline industry shortly after deregulation of the industry in the early 1980s. These programs provided model-based support to answer the central question faced by deregulated airlines: "How many bookings should I accept, for each fare product that I offer on each flight departure that I operate, so that I maximize my revenue?" Finding the best answers required developing statistical algorithms to predict the number of booked passengers who would show up and to predict the number of additional bookings to expect for each fare product. It also required developing optimization algorithms and formulations to find the best solution, given the characteristics of the forecasts. And for airlines operating hundreds to thousands of flights every day, and selling tickets for daily departures 300 days into the future, the computational challenges are extreme.
The yield management programs provided dramatic financial benefits to their early adopters in the early- to mid-1980s, and the approach spread rapidly to firms in the related sectors of hotel, rental car, and cruise line industries. While there are important differences between these industries, the dominant drivers of the solutions were the perishable nature of the resource being sold, demand patterns that were time-variable, and the limited capacity available for sale. For a good overview of pricing science methods and applications related to yield or revenue management, see Phillips and the references cited therein. Williams shows the connection between many of these problems and standard micro-economics.
Beginning in the early to mid-1990s, these successes spawned efforts to apply the methods, or develop new methods, to support pricing and related decisions in a variety of other settings. Yield management has been applied successfully to broadcast and cable television, online media, oil and gas producers, sporting and theatrical providers, online media, apartment and timeshare rental properties, credit card, and retail settings.
Since about 2000, the application of pricing science to the problems of quoting prices in business-to-business transactions has taken off |
https://en.wikipedia.org/wiki/Rock%20the%20World%20Youth%20Mission%20Alliance | Rock the World Youth Mission Alliance is a Christian ministry that trains young people as leaders. Their core training programs create an ongoing network of relationships where the grads and trainees collaborate to offer events and conferences, generate new ministries, and support one another in life and ministry.
Among other programs, Rock the World currently runs the Josiah Project, a summer collegiate leadership initiative; re:mix, a Great Commission conference for young people in college and high school; Third Culture Kid events for teens whose parents serve as Christian missionaries; "Striking Fire", a basic seminar in how to launch and lead local church youth ministry; and "Next Step" retreats for kids in middle school through high school. Rock the World's activities exist predominantly inside the USA but extend globally.
Mission of Rock the World
Rock the World's mission is to “engage, equip and empower young people to advance God's Kingdom.” The longer version of their mission states “Rock the World’s mission is to mobilize young people to follow Jesus, grow together in knowledge and love of God, serve in the power of the Spirit, and impact the world for the Kingdom of God.” Both versions emphasize the capacity of Jesus' young disciples to make more disciples. The long-term goal of RtW is to ignite a spiritual awakening among young people on every continent.
Rock the World is not legally a part of any denomination. At its founding, Rock the World was informally associated with the Episcopal Church. By the end of the 1990s this association had broadened to include a wide range of denominations. Although Rock the World is officially independent of any denomination, Anglican influence still finds expression through the involvement of so many Anglicans in the ministry. The Anglican Church in North America often involves Rock the World in their student ministries.
Founder
The Rev. Whis Hays founded Rock the World in 1989. After 14 years in ministry with college, high school, and middle school young people, he saw the need for a new ministry that gave leverage to the energy, dedication, and fresh insight of young Christian leaders. His published works include numerous articles and films, the best known of which are his 1995 article “Arresting the New Sexual McCarthyism” and his 1980 film, “Jesus, Head of the Church.” He is also known for 16 years of teaching youth ministry courses as Associate Professor of Youth Ministry at Trinity School for Ministry, teaching there while serving in his position as Rock the World’s Executive Director. For ten years he was also Assistant Director of Trinity's Stanway Institute of World Mission and Evangelism.
Name
The organization derives its name from the Bible's Book of Acts, chapter 17 verse 6. The story makes it clear that Paul and his friends were not trying to make trouble, but only trying to speak about Jesus and act according to the Kingdom of God. Obviously, sometimes this shook up things around |
https://en.wikipedia.org/wiki/Petascale%20computing | Petascale computing refers to computing systems capable of calculating at least 1015 floating point operations per second (1 petaFLOPS). Petascale computing allowed faster processing of traditional supercomputer applications. The first system to reach this milestone was the IBM Roadrunner in 2008. Petascale supercomputers were succeeded by exascale computers.
Definition
Floating point operations per second (FLOPS) are one measure of computer performance. FLOPS can be recorded in different measures of precision, however the standard measure (used by the TOP500 supercomputer list) uses 64 bit (double-precision floating-point format) operations per second using the High Performance LINPACK (HPLinpack) benchmark.
The metric typically refers to single computing systems, although can be used to measure distributed computing systems for comparison. It can be noted that there are alternative precision measures using the LINPACK benchmarks which are not part of the standard metric/definition. It has been recognised that HPLinpack may not be a good general measure of supercomputer utility in real world application, however it is the common standard for performance measurement.
History
The petaFLOPS barrier was first broken on 16 September 2007 by the distributed computing Folding@home project. The first single petascale system, the Roadrunner, entered operation in 2008. The Roadrunner, built by IBM, had a sustained performance of 1.026 petaFLOPS. The Jaguar became the second computer to break the petaFLOPS milestone, later in 2008, and reached a performance of 1.759 petaFLOPS after a 2009 update.
By 2018, Summit had become the world's most powerful supercomputer, at 200 petaFLOPS before Fugaku reached 415 petaFLOPS in June 2020.

https://en.wikipedia.org/wiki/Heroes%20Wiki | Heroes Wiki was a wiki-powered reference site for NBC's science fiction drama Heroes. Launched on October 10, 2006, the site uses MediaWiki software to maintain a user-created database of information. Heroes Wiki was supported by revenue from advertising, part of which is donated to various charities. As of June 28, 2010, the site contained over 5,500 articles created and edited by approximately 9,400 registered users, with over 157 million page views.
On October 18, 2008, Heroes Wiki announced that it had officially partnered with NBC. NBC now directs those interested in a wiki on Heroes to Heroes Wiki, and directly funds the site in exchange for on-site advertisements. The site was closed on June 1, 2020, due to low traffic rendering it unsustainable, but an archived copy has been made available online.
Overview
Heroes Wiki was launched on October 10, 2006, several weeks after Heroes premiered in North America. Content includes articles on episodes, characters, cast and crew, cultural references, along with interviews with members of the Heroes cast and crew. Episode spoilers and user-contributed theories was permitted on certain areas within the wiki. The site's main page featured upcoming Heroes events and news, and links to articles summarizing the latest Heroes episode and online content. There are also links to Heroes-related websites, including official websites affiliated with the show and its producers, websites used in Heroes Evolutions, and unofficial fan sites. On September 18, 2008, the site became WAP-enabled for cell phones and other mobile devices.
The site also established nine projects containing translations of the main English language version of the wiki: Dutch, French, German, Hebrew, Italian, Portuguese, Spanish, Swedish, and Turkish.
When Heroes Wiki began its partnership with NBC in October 2008, links were added pointing to Heroes Wiki on NBC's Heroes and Heroes Evolutions sites. NBC also discontinued promoting its own wiki for Heroes, instead redirecting readers to Heroes Wiki through links at the top of related pages. In December 2008, the wiki was also referenced in several segments of NBC's Heroes Insider Interactive SMS, which uses text messaging to send facts, pose trivia questions, and conduct polling during the airing of episodes of the show.
Role in Heroes Evolutions
As part of the alternate reality game in Heroes Evolutions, a mysterious Heroes character known only as Dropper Evs Dropper answered a number of fan-submitted questions posed by e-mail by Heroes Wiki administrator Gibson Stewart Ryan Gibson Stewart. The interview was posted at Heroes Wiki on July 24, 2008.
Reception
Beyond its partnership with NBC, Heroes Wiki had been recognized by other media outlets, including New York Magazine, the New York Times, and E! Online. Washington Times writer Joseph Szadkowski notes that the site is "obviously created by some very hard-core fans." He describes Heroes Wiki as a "dense online encyclopedia [that] o |

https://en.wikipedia.org/wiki/Recording%20thermometer | A recording thermometer is a type of thermometer that records temperature changes over a period of time. A digital recording thermometer is often called a temperature data logger.
Analog temperature recorders
A type of chart recorder, one end of a bi-metallic strip is attached to a long, light metal lever that holds a special pen. Tiny movements of the bimetallic strip cause much larger movements of the free end of the lever and the pen. The pen traces a rising and falling line on a strip of paper attached to a slowly turning drum. The drum usually makes one turn every seven or so days, so afterward each strip of paper contains a complete and accurate record of temperature changes for a whole week. The bimetallic strip is usually made from steel and copper. Because these metals expand and contract at different rates. When one of these metals expand it curls tighter, when one contracts it uncurls slightly. When it curls or uncurls, the data is converted into electric signals, which record the temperature change.
Digital temperature recorders
Thermocouple or thermistors sensors coupled with data loggers are now more often used to sense and record temperatures and record them in a digital format easily used by computers. They are widely available and come in a variety of types and varying probes.

https://en.wikipedia.org/wiki/Rotational%20mouse | A rotational mouse is a type of computer mouse which attempts to expand traditional mouse functionality. The objective of rotational mice is to facilitate three degrees of freedom (3DOF) for human-computer interaction by adding a third dimensional input, yaw (or Rz), to the existing x and y dimensional inputs. There have been several attempts to develop rotating mice, using a variety of mechanisms to detect rotation .
Mechanisms to detect rotation
Mechanisms using relative measures of rotation: These devices are able to detect that the mouse has rotated by so many degrees, but cannot accurately identify where the rotation started or ended, increasing their tendency to lose orientation.
2-balls and 4-sensor sets
1985 4 saw the first mention of a rotational mouse by Nomura, H. and Saitoh, A., entitled "mouse" at the IBM Technical Disclosure Bulletin, vol. 27, no. 6, Novembre 1984. pp. 3423-3424.
Other 2-ball / 4-sensor mouse concepts, patents:
"Cursor display apparatus" saw a mention of actually rotating objects on screen by rotating the input device, (1989).
Guaiá - A three degree of freedom mouse (in Portuguese - Guaiá)
Orientational mouse computer input system, (1992)
Multi-dimensional input device, (1994).
Positioning device reporting X, Y and yaw motion, (1995).
Twin mouse digitizer, (2000).
Pointing device having rotational sensing mechanisms, (2003).
Multiple sensor device and method, (2005).
Multiple sensor device and method, (2008).
Unlike the conventional mouse which senses z-axis and y-axis displacement only, these 2-ball or 2-sensor mice are also able to sense z-axis angular motion, calculated by the two sets of x-y displacement data .
Mechanical ring & rotary encoder
Within these devices rotation is detected by a mechanical ring. This mechanism was promoted by the Canadian company Handview Inc; however it apparently never made it to production.
Gyroscopes or accelerometers
A patent titled "Input device" was the first known application of gyros to a rotating mouse.
Mechanisms using absolute measures of rotation
Tablet/Digitiser Puck
The patent for an "Absolute position controller" is the earliest known reference to this type of input device. However, it was the patent for an orientational mouse computer input system, which suggested using a tablet with a detectable pattern or grid and sensors in the puck for computer navigation.
The Wacom Intuos 4D Mouse puck was the first commercial rotating “mouse.” The product was not a standalone mouse but rather a tablet accessory.
Compass
The Orbita mouse is the first commercially released non-tablet rotating mouse. Licensed and commercialized by Australian company Cyber Sport, the Orbita is equipped with a patented compass mechanism which solved the problems which plagued earlier rotating mechanisms. The inbuilt compass provides the mouse with ability to detect rotation based on the Earth's magnetic field so that it can accurately maintain orientation once the ‘up’ direction is spec |
https://en.wikipedia.org/wiki/Shred%20%28Unix%29 | is a command on Unix-like operating systems that can be used to securely delete files and devices so that it is extremely difficult to recover them, even with specialized hardware and technology; assuming it's even possible to recover the file at all. It is a part of GNU Core Utilities. Being based on the Gutmann method paper, it suffers from the same criticisms and possible shortcomings.
Background
For efficiency, the process of erasing a file from storage using the command usually only erases the file's file-system entry while keeping the content of the file intact. This frequently allows commonly available software to recover the "erased" file's data. If the file data is stored on magnetic media such as a HDD, even if the file is overwritten, residual magnetic fields may allow data recovery using specialist hardware equipment (this claim is disputed; see ). To prevent this, overwrites the contents of a file multiple times, using patterns chosen to maximize destruction of the residual data.
Features
can be invoked either on ordinary files or on devices (such as hard disk partitions), which are represented as files in Unix. By default, the command overwrites the file three times with multiple patterns, but the number is user configurable. It has an option to do an additional final overwrite with zeroes, which may help to hide the fact that it was used.
By default, shred also shreds file slack (unused space in file allocations). For example, a 5 KB file on a file system with 4 KB clusters actually requires 8 KB of storage. Shred has an option to overwrite only the file itself, as well as an option to delete the file after it has completed operation.
Limitations
A limitation of when invoked on ordinary files is that it only overwrites the data in place without overwriting other copies of the file. Copies can manifest themselves in a variety of ways, such as through manual and automatic backups, file system snapshots, copy-on-write filesystems, wear leveling on flash drives, caching such as NFS caching, and journaling. All limitations imposed by the file system can be overcome by shredding every device on which the data resides instead of specific files. However, since wear leveled devices do not guarantee a fixed relationship between logical blocks addressable through the interface and the physical locations in which the data is stored, shredding may not provide adequate security. If available, the SATA secure erase command, issued through hdparm or a similar utility, may be helpful in this situation. Even for magnetic devices, SATA secure erase will be faster and more reliable than shredding. Physical destruction may be necessary to securely erase devices such as memory cards and unusable hard disks.
Gutmann method, which is based on, is known to fail on USB sticks.

https://en.wikipedia.org/wiki/TerreStar%20Networks | TerreStar Networks, a majority owned subsidiary of TerreStar Corporation (TSTR), is a next generation, wholesale mobile communications provider launching the first integrated satellite terrestrial service with the world's first satellite-terrestrial smartphone.
Overview
TerreStar was to provide a fully integrated and resilient satellite+terrestrial mobile network. This network would leverage TerreStar's S band mobile satellite service (MSS) spectrum with an advanced all–IP ground-based open-architecture terrestrial network to provide voice, data and video services to end-users – from government officials and emergency first responders to adventure enthusiasts and consumers in rural communities.
TerreStar used commercial chipset technologies from Qualcomm and Infineon to embed satellite communications capabilities into smartphones that can be carried as everyday phones. Genus was the world's first (and only) Windows Mobile-based quad-band GSM and tri-band WCDMA/HSPA smartphone with integrated all-IP satellite-terrestrial voice and data capabilities, a touch screen and a full QWERTY keyboard. It resembled the now classic Blackberry design with a keyboard under the screen, used an internal antenna for terrestrial communications but required a rather large antenna for satellite communications.
World's Largest Satellite
On July 1, 2009, from French Guiana in South America, TerreStar launched its geosynchronous satellite, TerreStar-1. TerreStar-1 is the world's largest and most advanced commercial communications satellite that will provide communications services across the continental United States, Canada, Puerto Rico, U.S. Virgin Islands, Hawaii and Alaska. The satellite's size along with the extra power and sensitivity of its antenna allows it to communicate to conventionally sized mobile devices.
On July 14, 2009, TerreStar-1 successfully reached its orbital slot (at 111 degrees) in the geosynchronous arc and successfully deployed its 18-meter 2 GHz S Band reflector. On July 20, 2009, TerreStar completed the first end-to-end satellite-terrestrial phone call over TerreStar-1.

https://en.wikipedia.org/wiki/Halting%20problem | In computability theory, the halting problem is the problem of determining, from a description of an arbitrary computer program and an input, whether the program will finish running, or continue to run forever. The halting problem is undecidable, meaning that no general algorithm exists that solves the halting problem for all possible program–input pairs.
A key part of the formal statement of the problem is a mathematical definition of a computer and program, usually via a Turing machine. The proof then shows, for any program that might determine whether programs halt, that a "pathological" program , called with some input, can pass its own source and its input to f and then specifically do the opposite of what f predicts g will do. No f can exist that handles this case, thus showing undecidability. This proof is significant to practical computing efforts, defining a class of applications which no programming invention can possibly perform perfectly.
Background
The halting problem is a decision problem about properties of computer programs on a fixed Turing-complete model of computation, i.e., all programs that can be written in some given programming language that is general enough to be equivalent to a Turing machine. The problem is to determine, given a program and an input to the program, whether the program will eventually halt when run with that input. In this abstract framework, there are no resource limitations on the amount of memory or time required for the program's execution; it can take arbitrarily long and use an arbitrary amount of storage space before halting. The question is simply whether the given program will ever halt on a particular input.
For example, in pseudocode, the program
while (true) continue
does not halt; rather, it goes on forever in an infinite loop. On the other hand, the program
print "Hello, world!"
does halt.
While deciding whether these programs halt is simple, more complex programs prove problematic. One approach to the problem might be to run the program for some number of steps and check if it halts. However, as long as the program is running, it is unknown whether it will eventually halt or run forever. Turing proved no algorithm exists that always correctly decides whether, for a given arbitrary program and input, the program halts when run with that input. The essence of Turing's proof is that any such algorithm can be made to produce contradictory output and therefore cannot be correct.
Programming consequences
Some infinite loops can be quite useful. For instance, event loops are typically coded as infinite loops. However, most subroutines are intended to finish. In particular, in hard real-time computing, programmers attempt to write subroutines that are not only guaranteed to finish, but are also guaranteed to finish before a given deadline.
Sometimes these programmers use some general-purpose (Turing-complete) programming language,
but attempt to write in a restricted style—such as |
https://en.wikipedia.org/wiki/Opal%20Storage%20Specification | The Opal Storage Specification is a set of specifications for features of data storage devices (such as hard disk drives and solid state drives) that enhance their security.

https://en.wikipedia.org/wiki/VBS.tv | VBS.tv was an online television network owned by Vice Media, and later absorbed into VICE.com. The network produced original, short-form, documentary-style video content under the auspice of VICE Films. Subject matter included humanitarian issues, music, insider travel guides, and news. The creative director of the network was Spike Jonze.
History
Formation
VBS began as a deal between Viacom-owned MTV Networks and Logo Group. In March 2007, the network was formed; MTV funded the formation of the network, and Vice magazine would supply the content. MTV has rights to distribute VBS content across its worldwide network of channels. According to Vice co-founder Suroosh Alvi, "traditional journalism always aspires to objectivity, and since day one with the magazine we never believed in that...Our ethos is subjectivity with real substantiation. I don't think you see that on CNN."
Circulation
VBS videos are available via the network's website, as well as being broadcast on MTV Latin America and MTV2. VBS is currently featured as a weekly show on MTV2. VBS.tv content has appeared in CNN as part of their CNN presents line-up, with CNN stating that "... We believe this unique reporting approach is worthy of sharing with our CNN.com readers." Much of it is now available at VICE.com.
Content
The network's videos feature reporting on popular culture, travel, extreme sports, and music. The site has also produced special-interest and current affairs-based shows such as an interview with Hezbollah's self-proclaimed mayor of Beirut and a show that explored allegations of environmental abuse. It has also approached drug issues, producing a documentary about the criminal use of the drug scopolamine in Colombia, a report on cocaine smuggling submarines and a documentary on hallucinogenic frogs in the Amazon rainforest. Other coverage includes a series of short documentaries about Darfur, Hurricane Katrina, Liberia, North Korea and suicide in Japan's Aokigahara Forest. The network also produced Heavy Metal in Baghdad, a feature-length documentary film about Acrassicauda. The director of content of the network was Santiago Stelley.

https://en.wikipedia.org/wiki/AS1%20%28networking%29 | AS1 (Applicability Statement 1) is a specification about how to transport structured business-to-business data securely and reliably over the Internet. Security is achieved by using digital certificates and encryption.
AS1 technical overview
The AS1 protocol is based on SMTP and S/MIME. It was the first AS protocol developed and uses signing, encryption and MDN conventions. In other words:
Files are sent as "attachments" in a specially coded SMIME email message
Messages can be signed, but do not have to be
Messages can be encrypted, but do not have to be
Messages may request an MDN back if all went well, but do not have to request such a message
If the original AS1 message requested an MDN...
Upon the receipt of the message and its successful decryption or signature validation (as necessary) a "success" MDN will be sent back to the original sender. This MDN is typically signed but not encrypted.
Upon the receipt and successful verification of the signature on the MDN, the original sender will "know" that the recipient got their message (this provides the "Non-repudiation" element of AS1)
If there are any problems receiving or interpreting the original AS1 message, a "failed" MDN may be sent back.
Like any other AS file transfer, AS1 file transfers typically require both sides of the exchange to trade X.509 certificates and specific "trading partner" names before any transfers can take place.

https://en.wikipedia.org/wiki/Cloud%20testing | Cloud testing is a form of software testing in which web applications use cloud computing environments (a "cloud") to simulate real-world user traffic.
Steps
Companies simulate real world Web users by using cloud testing services that are provided by cloud service vendors such as Advaltis, Compuware, HP, Keynote Systems, Neotys, RadView and SOASTA. Once user scenarios are developed and the test is designed, these service providers leverage cloud servers (provided by cloud platform vendors such as Amazon.com, Google, Rackspace, Microsoft, etc.) to generate web traffic that originates from around the world. Once the test is complete, the cloud service providers deliver results and analytics back to corporate IT professionals through real-time dashboards for a complete analysis of how their applications and the internet will perform during peak volumes.
Applications
Cloud testing is often seen as only performance or load tests, however, as discussed earlier it covers many other types of testing. Cloud computing itself is often referred to as the marriage of software as a service (SaaS) and utility computing. In regard to test execution, the software offered as a service may be a transaction generator and the cloud provider's infrastructure software, or may just be the latter. Distributed Systems and Parallel Systems mainly use this approach for testing, because of their inherent complex nature. D-Cloud is an example of such a software testing environment.
Tools
Leading cloud computing service providers include, among others, Amazon, Microsoft, Google, RadView, Skytap, HP and SOASTA.
Benefits
The ability and cost to simulate web traffic for software testing purposes has been an inhibitor to overall web reliability. The low cost and accessibility of the cloud's extremely large computing resources provides the ability to replicate real world usage of these systems by geographically distributed users, executing wide varieties of user scenarios, at scales previously unattainable in traditional testing environments. Minimal start-up time along with quality assurance can be achieved by cloud testing.
Following are some of the key benefits:
Reduction in capital expenditure
Highly scalable

https://en.wikipedia.org/wiki/WirelessHART | WirelessHART within telecommunications and computing, is a wireless sensor networking technology. It is based on the Highway Addressable Remote Transducer Protocol (HART). Developed as a multi-vendor, interoperable wireless standard, WirelessHART was defined for the requirements of process field device networks.
Technical description
The protocol utilizes a time synchronized, self-organizing, and self-healing mesh architecture. The protocol supports operation in the 2.4 GHz ISM band using IEEE 802.15.4 standard radios. The underlying wireless technology is based on the work of Dust Networks' TSMP technology.
History
The standard was initiated in early 2004 and developed by 37 HART Communications Foundation (HCF) companies that - amongst others - included ABB, Emerson, Endress+Hauser, Pepperl+Fuchs, Siemens, Freescale Semiconductor, Software Technologies Group (which developed the initial WirelessHART WiTECK stack), and AirSprite Technologies which went on to form WiTECK, an open non-profit membership organization whose mission is to provide a reliable, cost-effective, high-quality portfolio of core enabling system software for industrial wireless sensing applications, under a company and platform-neutral umbrella.
WirelessHART was approved by a vote of the 210 member general HCF membership, ratified by the HCF Board of Directors, and introduced to the market in September 2007. On September 27, 2007, the Fieldbus Foundation, Profibus Nutzerorganisation, and HCF announced a wireless cooperation team to develop a specification for a common interface to a wireless gateway, further protecting users' investments in technology and work practices for leveraging these industry-pervasive networks. Following its completed work on the WirelessHART standard in September 2007, the HCF offered International Society of Automation (ISA) an unrestricted, royalty-free copyright license, allowing the ISA100 committee access to the WirelessHART standard.
Backward compatibility with the HART “user layer” allows transparent adaptation of HART compatible control systems and configuration tools to integrate new wireless networks and their devices, as well as continued use of proven configuration and system-integration work practices. It is estimated that 25 million HART field devices are installed worldwide, and approximately 3 million new wired HART devices are shipping each year. In September 2008, Emerson became the first process automation supplier to begin production shipments for its WirelessHART enabled products.
During the summer of 2009 NAMUR, an international user association in the chemical and pharmaceutical processing industries, conducted a field test of WirelessHART to verify alignment with the NAMUR requirements for wireless automation in process applications.
WirelessHart was approved by the International Electrotechnical Commission (IEC) in January 2009 with revision released in April 2010. The latest edition, version 2, was released in 2016 as |

https://en.wikipedia.org/wiki/Data%20Stream%20Interface | The Data Stream Interface (DSI) is a session layer used to carry Apple Filing Protocol traffic over Transmission Control Protocol.
Overview
When Apple introduced TCP with MacTCP and Open Transport in System 7 in the 1990s, they needed their file sharing protocol (AFP) to run on both TCP and AppleTalk. They introduced AppleTalk Session Protocol (ASP) and DSI for TCP coincidentally with AFP 2.x.
DSI is implemented directly into AFP clients such as in Mac OS and afpfs-ng.
Protocol
DSI is spoken between a client and an AFP server. All DSI communication contains the following DSI header:
Packet structure
The fields are:
Flags: whether the packet is a request (0x00) or a reply (0x01)
Command: one of 7 possible commands (see below)
Request ID: a sequential identifier set on the request and copied in the reply
Error code/ enclosed data offset:
For requests, this is left as 0, except when using the DSIWrite command.
For replies, this is an error code.
Total data length: the entire length of data after the DSI header
Reserved: for future expansion
Payload: this is where limited DSI data or more commonly AFP header is placed
Commands
There are seven possible commands:
Requests and replies
Upon receiving most DSI requests, the client or server sends a reply message. This reply contains:
the flags field set to 0x01 (reply)
the command field set to the same value as the request's command field
the same request ID sent in the request (used for the client to find the request being acknowledged)
totalDataLength set to the payload length (if applicable).
where applicable, the data payload itself following the DSI header. (See the individual command for details.)
The DSITickle and DSICloseSession commands do not trigger a reply.
Session creation, maintenance and teardown
A session is set up by the client sending a DSIOpenSession, which will include the size of the receive buffer the client has for packets (called the request quantum, typically 1024 bytes). The server acknowledges the request and returns the size of its data receive buffer (typically 256k on Mac OS X Leopard).
Session closure can be initiated by either side by sending DSICloseSession. The sender does not need to wait for a reply and should immediately close the session after sending the message.
Maintaining the connection is done by tickling. DSI provides a mechanism for ensuring that client and server know that the other is still active. Every 30 seconds of inactivity, the server sends a tickle request to the client. Similarly, the client also sends its own tickle. (This is NOT a response packet.) Either the client or server can terminate the DSI session if they fail to hear from the other for 120 seconds. The client may also disconnect if a request is in flight and neither a response nor tickle is received within 60 seconds (in Mac OS X v.10.2 and later).
Getting server information with GetStatus
This DSI command encapsulates an FPGetSrvrInfo packet. |

https://en.wikipedia.org/wiki/ServerNet | ServerNet is a switched fabric communications link primarily used in proprietary computers made by Tandem Computers, Compaq, and HP.
Its features include good scalability, clean fault containment, error detection and failover. The ServerNet architecture specification defines a connection between nodes, either processor or high performance I/O nodes such as storage devices.
History
Tandem Computers developed the original ServerNet architecture and protocols for use in its own proprietary computer systems starting in 1992, and released the first ServerNet systems in 1995. Early attempts to license the technology and interface chips to other companies failed, due in part to a disconnect between the culture of selling complete hardware / software / middleware computer systems and that needed for selling and supporting chips and licensing technology. A follow-on development effort ported the Virtual Interface Architecture to ServerNet with PCI interface boards connecting personal computers. Infiniband directly inherited many ServerNet features. As of 2017, systems still ship based on the ServerNet architecture.

https://en.wikipedia.org/wiki/KWHS-LD | KWHS-LD (channel 51) is a low-power religious television station in Colorado Springs, Colorado, United States, owned and operated by the Christian Television Network (CTN). The station's transmitter is located atop Cheyenne Mountain.
History
The station, which signed on the air in 1992 and maintains a studio in Colorado Springs, was previously a semi-satellite of KWHD in Denver, owned by LeSEA Broadcasting (now Family Broadcasting Corporation). Both outlets shared the same programming with some exceptions. (KWHD is now KETD, carrying Estrella TV; the station does still operate a subchannel carrying a schedule of religious programming that remained identical to that of KWHS until 2018.)
In June 2014, it was announced LeSEA had inked an affiliation deal with Cozi TV, KWHS-LD was one of the stations that began carrying the channel. On July 1, 2017, Light TV replaced Cozi TV on KWHS-LD's subchannel.
On February 5, 2018, it was announced that LeSEA would sell KWHS-LD, along with Class A station KEEN-CD in Las Vegas and full-power station WHNO in New Orleans, to Clearwater, Florida-based Christian Television Network for $5.7 million. The sale was completed on April 23, 2018.

https://en.wikipedia.org/wiki/Bologna%E2%80%93Florence%20railway | The Bologna–Florence railway is one of the major links in the Italian rail network, connecting the railways of the Po Valley with the railways of Tuscany and central Italy under the Apennines. It is also known as the Bologna–Florence direttissima—"direttissima" is Italian for "most direct". It was Italy's greatest engineering achievement in the first half of the twentieth century. When it opened in 1934 it significantly shortened the old winding Porrettana line over the Apennines via Pistoia, and was made possible by the 18.507 km-long Apennine Base Tunnel. The new Bologna–Florence high-speed railway was opened on 5 December 2009; it includes 73.8 km of tunnels in its 78.5 km length.
History
The Porrettana line was opened across the Apennines between Bologna and Florence via Pistoia and Prato in November 1864 to connect the trunk railway of the Po Valley (the Milan–Bologna and the Bologna–Ancona railways, completed in 1861) with the railways of Tuscany. Florence was finally connected by rail with Rome via Perugia in 1866. The Porrettana line was immediately successful but while it was a significant engineering achievement it soon became clear that it was inadequate to cater for the traffic attempting to use it. In particular, it was a single track line, with steep gradients and its Apennine tunnel was built on a steep slope causing climbing steam trains to generate suffocating smoke, even when extra ventilation shafts and fans were eventually installed.
Various projects for additional crossings of the Apennines were developed, and the Pontremolese line was opened in 1892 between La Spezia and Parma providing an alternative route from Rome to Milan. The Faentina line was opened in 1893 from Florence to Faenza as another alternative route. However these lines suffered from the same basic problem: they were mountain lines consisting of a single, winding track and were subject to being obstructed by snow in winter. As time passed, traffic increased, but so did technical expertise in drilling long tunnels, so it became possible to envisage more direct routes with reduced climbs up a pass.
In 1882 the designer of Porrettana, Jean Louis Protche, was commissioned by several institutions to examine a number of projects including one dating back to 1871, proposed by the engineer Antonio Zannoni which proposed a more easterly route for the new line in order to reduce the length of climb. Protche chose a slightly different route through the valleys of the Setta and Bisenzio rivers, connecting with the existing line in Prato, and passing under the Apennines through an 18,032 m tunnel; its approach line would have had a total vertical climb of 328 m at a maximum slope of 12 per thousand.
In 1902, the Colombo Commission was established to study the proposals of Protche and Zannoni along with those of several other engineers, Sugliano, De Gaetani, Naldoni and Mercanti. In 1908 the government authorised for a budget of 150 million lire for final studies fo |

https://en.wikipedia.org/wiki/Ruzena%20Bajcsy | Ruzena Bajcsy (born 1933 in Bratislava, now Slovakia) is an American engineer and computer scientist who specializes in robotics. She is professor of electrical engineering and computer sciences at the University of California, Berkeley, where she is also director emerita of CITRIS (the Center for Information Technology Research in the Interest of Society).
She was previously professor and chair of computer science and engineering at the University of Pennsylvania, where she was the founding director of the University of Pennsylvania's General Robotics and Active Sensory Perception (GRASP) Laboratory, and a member of the Neurosciences Institute in the School of Medicine. She has also been head of the National Science Foundation's Computer and Information Science and Engineering Directorate, with authority over a $500 million budget. She supervised at least 26 doctoral students who received the Ph.D. at Pennsylvania.
She was elected a member of the American Philosophical Society in 2005.
She is the mother of computer-science professor Klara Nahrstedt.
Early life
Bajcsy was born in 1933 in Bratislava, now Slovakia to a Jewish family. Although her family was initially spared from Nazi concentration camps due to her father's work as a civil engineer, most of her adult relatives were killed by the Nazis in late 1944. Bajcsy and her sister, the only survivors in the immediate family, were supported as war orphans by the Red Cross; Bajcsy was later raised in orphanages and in foster care. A strong student in mathematics, she has said that she chose instead to study electrical engineering as a university student because the career prospects for mathematics students at the time led to teaching, which in Communist Eastern Europe required a commitment to Marxist-Leninist ideology that she was unwilling to provide.
Education
She obtained Master's and Ph.D. degrees in electrical engineering from Slovak Technical University in 1957 and 1967, and an additional Ph.D. in computer science in 1972 from Stanford University. Her thesis was "Computer Identification of Textured Visual Scenes", and her advisor was John McCarthy.
In 2001, she received an honorary doctorate from the University of Ljubljana in Slovenia. From 2003 to 2005, she was a member of the President's Information Technology Advisory Committee. The November 2002 issue of Discover named her to its list of the 50 most important women in science. In 2012, she received honorary doctorate degrees from the University of Pennsylvania and KTH, The Royal Institute of Technology in Sweden.
Writings
She has written over 225 articles in journals and conference proceedings, 25 book chapters, and 66 technical reports and has been on many editorial boards.
Current research
Her current research centers on artificial intelligence; biosystems and computational biology; control, intelligent systems, and robotics; graphics and human-computer interaction, computer vision; and security.

https://en.wikipedia.org/wiki/Bregman%20method | The Bregman method is an iterative algorithm to solve certain convex optimization problems involving regularization. The original version is due to Lev M. Bregman, who published it in 1967.
The algorithm is a row-action method accessing constraint functions one by one and the method is particularly suited for large optimization problems where constraints can be efficiently enumerated. The algorithm works particularly well for regularizers such as the norm, where it converges very quickly because of an error-cancellation effect.
Algorithm
In order to be able to use the Bregman method, one must frame the problem of interest as finding , where is a regularizing function such as .
The Bregman distance is defined as where belongs to the subdifferential of at (which we denoted ). One performs the iteration , with a constant to be chosen by the user (and the minimization performed by an ordinary convex optimization algorithm), or , with chosen each time to be a member of .
The algorithm starts with a pair of primal and dual variables. Then, for each constraint a generalized projection onto its feasible set is performed, updating both the constraint's dual variable and all primal variables for which there are non-zero coefficients in the constraint functions gradient. In case the objective is strictly convex and all constraint functions are convex, the limit of this iterative projection converges to the optimal primal dual pair.
In the case of a basis pursuit-type problem , the Bregman method is equivalent to ordinary gradient descent on the dual problem . An exact regularization-type effect also occurs in this case; if exceeds a certain threshold, the optimum value of is precisely the optimum solution of .
Applications
The Bregman method or its generalizations can be applied to:
Image deblurring or denoising (including total variation denoising)
MR image reconstruction
Magnetic resonance imaging
Radar
Hyperspectral imaging
Compressed sensing
Least absolute deviations or -regularized linear regression
Covariance selection (learning a sparse covariance matrix)
Matrix completion
Structural risk minimization
Generalizations and drawbacks
The method has links to the method of multipliers and dual ascent method (through the so-called Bregman alternating direction method of multipliers, generalizing the alternating direction method of multipliers) and multiple generalizations exist.
One drawback of the method is that it is only provably convergent if the objective function is strictly convex. In case this can not be ensured, as for linear programs or non-strictly convex quadratic programs, additional methods such as proximal gradient methods have been developed. In the case of the Rudin-Osher-Fatemi model of image denoising, the Bregman method provably converges.
Some generalizations of the Bregman method include:
Inverse scale space method
Linearized Bregman
Logistic Bregman

https://en.wikipedia.org/wiki/StatView | StatView is a statistics application originally released for Apple Macintosh computers in 1985.
StatView was one of the first statistics applications to have a graphical user interface, capitalizing on the Macintosh's. A user saw a spreadsheet of his or her data, comprising columns that could be integers, long integers, real numbers, strings, or categories, and rows that were usually cases (such as individual people for psychology data). Columns had informative headings; rows were numbered. Category data looked like strings (e.g., a column headed "sex" would have entries of "male" and "female", but these were coded by the application as integers). Category data were used to perform inferential statistical tests such as t tests, ANOVAs, and chi square tests. To calculate statistics, a user clicked on particular column headings, designating them as an x value and one or more y values. Then the user used the application's menus to choose descriptive statistics or inferential statistics.
For example, a user's spreadsheet might contain columns for names of a participant in a survey (a string), sex (a category variable), IQ (integer), and years using a PC (real). By designating number of years using a PC as an x variable and IQ as a y variable, the user could then choose from a menu to perform a regression. The user then had to choose from another menu how to view the regression in a separate window, either as a table, in which case the regression equation and ANOVA were displayed, or as a scattergram, in which case a graph of the data and the regression line were shown. Contents of the analysis window could be copied either as text or as a PICT.
StatView was initially distributed by BrainPower Inc from California. It grew up with the Macintosh, changing owners along the way. StatView 3 to 5 were distributed by Abacus Corporation. It was then bought by SAS which discontinued it in favor of JMP. The application continued to run under Classic emulation with Apple's Mac OS X, but could not run on Intel Macintoshes. , it still runs under OS 10.7.5 emulation using Basilisk II.
StatView 2 was called StatView SE + Graphics. It included ANOVA with one repeated-measure and, remarkably, a factor analysis. In StatView 4, the user approach changed from touching the to-be-analyzed data in the spreadsheet to clicking on column names in a separate window. This lack of immediacy was compensated for by an increase in the number of statistical tests that could be performed and in the power of existing tests. For example, multiway repeated-measures factors could be included in ANOVAs, with the only limit being the memory allocated to the application. There were ANCOVA and MANOVA too. StatView 4 also became available for PCs.
Statview 5.01 for Windows runs without issue on Windows XP, Windows 7 Home and Pro, both 32- and 64-bit systems. (This does not appear to actually be the case, the only method on Windows 7 appears to be using XP Mode.) It appears to run without |
https://en.wikipedia.org/wiki/CDR%20computerized%20assessment%20system | The CDR computerized assessment system (CDR system) is a computerized battery of cognitive tests designed in the late 1970s by Professor Keith Wesnes at the University of Reading in Berkshire, England, for repeated testing in clinical trials. Task stimuli are presented in a laptop computer and participants respond via 'YES' and 'NO' buttons on a two-button response box, which records both the accuracy and reaction time.
The CDR system is a computer based cognitive testing tool, developed to assess both enhancement and impairment of human cognitive performance. The CDR system's simplicity, sensitivity and specificity makes it acceptable to be used in clinical trials with either healthy subjects or diseased patient populations. The CDR system software is loaded onto laptop computers for testing in medical clinics. An internet version of the CDR system is available using keyboard commands to measure responses. Ancillary equipment is used for specific cognitive tests such as a postural stability (sway) meter, a critical flicker fusion device or joysticks for CDR's tracking test.
The CDR system is a series of brief neuropsychological tests that assess major aspects of cognitive function known to be influenced by a wide variety of factors including trauma, fatigue, stress, nutrition, ageing, disease (both physical and mental), medicines and drugs. The standard battery of cognitive tests in The CDR system includes immediate/delayed word recall, word recognition, picture recognition, simple reaction time, digit vigilance, choice reaction time, numeric working memory, and spatial working memory. Individual tests can be added to or removed from the battery to target specific cognitive domains. Examples of tests that can be added include measurements of executive function, mood states, social cognition, motor function and postural stability. The standard battery of tests lasts 18 minutes.
The CDR system tasks have proven validity in definitively measuring cognitive function in a variety of domains including attention, working memory, episodic secondary memory, executive function, and motor skill.
In September, 2009, Cognitive Drug Research was acquired by United BioSource Corporation. UBC division Bracket continues to offer the CDR System for use in clinical research.

https://en.wikipedia.org/wiki/Cultural%20analytics | Cultural analytics refers to the use of computational, visualization, and big data methods for the exploration of contemporary and historical cultures. While digital humanities research has focused on text data, cultural analytics has a particular focus on massive cultural data sets of visual material – both digitized visual artifacts and contemporary visual and interactive media. Taking on the challenge of how to best explore large collections of rich cultural content, cultural analytics researchers developed new methods and intuitive visual techniques that rely on high-resolution visualization and digital image processing. These methods are used to address both the existing research questions in humanities, to explore new questions, and to develop new theoretical concepts that fit the mega-scale of digital culture in the early 21st century.
History
The term "cultural analytics" was coined by Lev Manovich in 2007. After 2016, this term started to be increasingly used by other researchers, and many University programs in cultural analytics were gradually established. Journal of Cultural Analytics started to be published in 2016. Manovich's own monograph Cultural Analytics is being published by The MIT Press in the Fall of 2020.
Cultural analytics shares many ideas and approaches with visual analytics ("the science of analytical reasoning facilitated by visual interactive interfaces") and visual data analysis:
Visual data analysis blends highly advanced computational methods with sophisticated graphics engines to tap the extraordinary ability of humans to see patterns and structure in even the most complex visual presentations. Currently applied to massive, heterogeneous, and dynamic datasets, such as those generated in studies of astrophysical, fluidic, biological, and other complex processes, the techniques have become sophisticated enough to allow the interactive manipulation of variables in real time. Ultra high-resolution displays allow teams of researchers to zoom in to examine specific aspects of the renderings, or to navigate along interesting visual pathways, following their intuitions and even hunches to see where they may lead. New research is now beginning to apply these sorts of tools to the social sciences and humanities as well, and the techniques offer considerable promise in helping us understand complex social processes like learning, political and organizational change, and the diffusion of knowledge.
While increased computing power and technical developments allowing for interactive visualization have made the exploration of large data sets using visual presentations possible, the intellectual drive to understand cultural and social processes and production pre-dates many of these computational advances. Charles Joseph Minard's famous dense graphic showing Napoleon's March on Moscow (1869) offers a 19th-century example.

https://en.wikipedia.org/wiki/Correlation%20clustering | Clustering is the problem of partitioning data points into groups based on their similarity. Correlation clustering provides a method for clustering a set of objects into the optimum number of clusters without specifying that number in advance.
Description of the problem
In machine learning, correlation clustering or cluster editing operates in a scenario where the relationships between the objects are known instead of the actual representations of the objects. For example, given a weighted graph where the edge weight indicates whether two nodes are similar (positive edge weight) or different (negative edge weight), the task is to find a clustering that either maximizes agreements (sum of positive edge weights within a cluster plus the absolute value of the sum of negative edge weights between clusters) or minimizes disagreements (absolute value of the sum of negative edge weights within a cluster plus the sum of positive edge weights across clusters). Unlike other clustering algorithms this does not require choosing the number of clusters in advance because the objective, to minimize the sum of weights of the cut edges, is independent of the number of clusters.
It may not be possible to find a perfect clustering, where all similar items are in a cluster while all dissimilar ones are in different clusters. If the graph indeed admits a perfect clustering, then simply deleting all the negative edges and finding the connected components in the remaining graph will return the required clusters.
But, in general a graph may not have a perfect clustering. For example, given nodes a,b,c such that a,b and a,c are similar while b,c are dissimilar, a perfect clustering is not possible. In such cases, the task is to find a clustering that maximizes the number of agreements (number of + edges inside clusters plus the number of − edges between clusters) or minimizes the number of disagreements (the number of − edges inside clusters plus the number of + edges between clusters). This problem of maximizing the agreements is NP-complete (multiway cut problem reduces to maximizing weighted agreements and the problem of partitioning into triangles can be reduced to the unweighted version).
Formal Definitions
Let be a graph with nodes and edges . A clustering of is a partition of its node set with and for .
For a given clustering , let denote the subset of edges of whose endpoints are in different subsets of the clustering .
Now, let be a function that assigns a non-negative weight to each edge of the graph and let be a partition of the edges into attractive () and repulsive () edges.
The minimum disagreement correlation clustering problem is the following optimization problem:
Here, the set contains the attractive edges whose endpoints are in different components with respect to the clustering and the set contains the repulsive edges whose Endpoints are in the same component with respect to the clustering .
Together these two sets contain al |
https://en.wikipedia.org/wiki/Databank%20format | A file format is a procedure to encode information for storage in a computer file.
The databank format is an ASCII file format for time series econometric analysis. The format was popularized by MicroTSP.
The databank format is used for data of a fixed annual sample frequency (annual, quarterly, monthly) and for undated data. It is supported by TSP, EViews, and many other econometric applications. Traditionally the name of the file ends with extension .db.
By inspection, the databank file is seen to be an ASCII text file containing a single data series. A databank file is formatted in a linewise structure. Initial comment lines begin with a quote. For dated series, the next three lines specify the frequency, start date, and end date. (For undated series, the next two lines specify the start index and end index.) The remaining lines are data: one observation per line, or NA if missing.
Closely related is the open databank format: a modest extension and more detailed
specification of the traditional databank format. A conforming reader and writer is provided by EconPy.

https://en.wikipedia.org/wiki/Michael%20Homer | Michael J. Homer (February 24, 1958 – February 1, 2009) was an American electronics and computer industry executive who played major roles in the development of the personal computer, mobile devices and the Internet.
Life and career
Homer was born in San Francisco on February 24, 1958 and was awarded a bachelor's degree at the University of California, Berkeley.
He was hired by Apple Computer in 1982, where he served as the technology adviser to the firm's chief executive, John Sculley. He followed with a position as marketing vice president at GO Corp., an early pioneer in creating software for mobile computers and personal digital assistants that did early work in pen-based computing.
After Go closed in 1994, John Doerr of Kleiner Perkins Caufield & Byers, Go's main venture capital backer, made the connection for Homer at Marc Andreessen's Netscape Communications Corporation. Homer was a vice president at the Netscape in the 1990s at the dawn of the World Wide Web. There, Homer developed the company's initial business plan and played a pivotal role in obtaining the private financing necessary to allow the company to progress to its 1995 initial public offering. He developed marketing plans for Netscape in 1994 at a time when few people had ever heard of the Internet. During the period where Microsoft challenged Netscape's early browser dominance with its Internet Explorer product, Homer headed the firm's marketing department as it faced bitter competition from Microsoft, a challenge that ultimately resulted in an antitrust suit. Homer helped argue that Microsoft had abused its monopoly power in the operating system market to push out Netscape's browser in favor of its own.
Following AOL's acquisition of Netscape in 2000, Homer founded Kontiki, a peer-assisted content delivery technology company, that was purchased by VeriSign in March 2006 for $62 million, with a proviso that the rights to use the firm's technology would be donated to the non-profit Open Media Network. Homer fostered the early growth of a series of technology firms, including roles in the development of Google, Tellme Networks and TiVo, and sat on the board of Palm, Inc.
Illness
In 2007, persistent memory problems he had been experiencing led to a diagnosis of Creutzfeldt–Jakob disease, a very rare and incurable degenerative neurological disorder. Several people close to him created "Fight for Mike", an organization that raised $7 million used to fund research in the neurology department of the University of California, San Francisco towards study and potential cure of the disease. The team at UCSF includes Dr. Stanley B. Prusiner, winner of the Nobel Prize in Physiology or Medicine in 1997 for his discovery of the prion, misfolded proteins that trigger CJD and bovine spongiform encephalopathy ("mad cow disease"). The team at UCSF was studying the use of Quinacrine, long used as an antimalarial drug, in the treatment of CJD.
Homer died at age 50 on February 1, 2009 in A |
https://en.wikipedia.org/wiki/Metadata%20controller | Metadata controller (or MDC) is a storage area network (SAN) technology for managing file locking, space allocation and data access authorization.
This is needed when several clients are given block level access to the same disk volume, data storage sharing.
MDCs are only used on high-end servers. These are never found on user computers. In the absence of MDC over a SAN there is no possible way of ensuring privacy of the stored data. This controller can also play its role as a sharing device in case the administrators allow other servers to access certain blocks in a particular SAN. The access granted to the servers is of different levels. Some times it may happen that the server is not able to see a block or make changes in it in case of a locked file. This is caused by grant of low level access. If different clients on SAN happen to know each other, access may be granted to shift a certain block from one server to another. This allows the recipient server to use the block and make changes in it.
MDCs work as enzymes. They require certain types of SANs and networks to work properly. If a controller is connected to the right network it will boost its output. In case of wrong connection i.e. with the incorrect network, it will decrease its performance.

https://en.wikipedia.org/wiki/ConsensusPathDB | The ConsensusPathDB is a molecular functional interaction database, integrating information on protein interactions, genetic interactions signaling, metabolism, gene regulation, and drug-target interactions in humans. ConsensusPathDB currently (release 30) includes such interactions from 32 databases. ConsensusPathDB is freely available for academic use under http://ConsensusPathDB.org.
Integrated Databases
Reactome (metabolic and signaling pathways)
KEGG (metabolic pathways only have been integrated in ConsensusPathDB)
HumanCyc (metabolic pathways)
PID - Pathway Interaction Database (signaling pathways)
BioCarta (signaling pathways)
Netpath (signaling pathways)
IntAct (protein interactions)
DIP (protein interactions)
MINT (protein interactions)
HPRD (protein interactions)
BioGRID (protein interactions)
SPIKE (protein interactions, signaling reactions)
WikiPathways (metabolic and signaling pathways)
and many more.
Functionalities
The ConsensusPathDB is accessible via a web interface providing a variety of functions.
Search and visualization
Using the web interface users can search for physical entities (e.g. proteins, metabolites etc.) or pathways using common names or accession numbers (e.g. UniProt identifiers). Selected interactions can be visualized in an interactive environment as expandable networks. ConsensusPathDB currently allows users to export their models in BioPAX format or as image in several formats.
Shortest path
Users can search for shortest paths of functional interactions between physical entities, based on all interactions in the database. The pathway search can be constrained by forbidding passing through certain physical entities.
Data upload
Users can upload their own interaction networks in BioPAX, PSI-MI or SBML files in order to validate and/or extend those networks in the context of the interactions in ConsensusPathDB.
Over-representation analysis
Using the web-interface of the database, one can perform overrepresentation analysis, based on biochemical pathways or on neighbourhood-based entity sets (NESTs) that constitute sub-networks of the overall interaction network containing all physical entities around a central one within a "radius" (number of interactions from the center). For each predefined set (pathway / NEST), a P-value is computed based on the hypergeometric distribution. It reflects the significance of the observed overlap between the user-specific input gene list and the members of the predefined set.
Over-representation analyses can be performed with user-specified genes or metabolites.

https://en.wikipedia.org/wiki/Psion%20Teklogix | Psion Teklogix Inc. was the operational business of Psion.
Psion Teklogix is a global provider of solutions for mobile computing and wireless data collection. Psion Teklogix' products and services include rugged mobile hardware, secure wireless networks, software, professional services and support programs.
Psion Teklogix was formed in September 2000 as a result of the merger between U.K.-based Psion Enterprise division of Psion PLC, and Canadian-based Teklogix Inc.
Psion Teklogix is headquartered in Mississauga, Ontario, Canada with additional corporate offices located in Europe, the United States, Asia, Latin America and the Middle East.
Psion Teklogix is an ISO 9001:2000 registered company, and holds a certificate of registration from the British Standards Institution.
In 2012 Motorola Solutions purchased Psion Teklogix for $200 million.
In October 2014, the Motorola Solutions' enterprise business (including assets acquired in the Psion Teklogix purchase) was sold to Zebra Technologies for $3.45B.
History
Teklogix was created in 1967 by Rod Coutts, a 1964 bachelor of applied science in electrical engineering, together with a small group of young Canadian engineers. The company grew to specialize in empowering mobile workers with wireless data transmission and real-time data management within the logistics industry.
The Psion Group, founded in 1980 by David Potter, is widely credited with having created the world's first volume produced PDA with the launch of the Psion Organiser in 1984. Generally recognized as the world's first practical pocket computer, the Organiser helped evolve Psion into a major technology player.
In 2000 Psion acquired Teklogix in Canada for £240 million, and merged its business-to-business division, Psion Enterprise, with the newly acquired company. Teklogix was re-branded Psion Teklogix. This division now forms the core of Psion Plc's business.
In 2002 Psion Teklogix created a new division called Psion Software. This business developed push email solutions for Symbian smartphones, Microsoft Exchange and Lotus Notes. This business was sold to Visto (USA) in 2003.
In 2004, Psion Teklogix announced its intention to dispose of the company's remaining Symbian shareholding to Nokia, as they no longer regarded it as a core part of their strategy.
In 2005, Psion Teklogix acquired Ottawa-based image capture firm Symagery Microsystems.
In 2012, Psion Teklogix was acquired by Motorola for US$200 million.
Psion Teklogix and Linux
Psion PLC had a lengthy, but distant, interest in Linux as an operating system on its electronic devices. In 1998, it supported the Linux7K project that had been initiated by Ed Bailey at Red Hat, which was to port Linux to its Series 5 personal computer. The project was named after the
Cirrus Logic PS-7110 chip of the Series 5. Although this project was one of the earliest attempts to port Linux to a handheld computer, it did not come to fruition for Psion. The project soon transition |
https://en.wikipedia.org/wiki/Webmonkey | Webmonkey was an online tutorial website composed of various articles on building webpages from backend to frontend. The site covered many aspects of developing on the web like programming, database, multimedia, and setting up web storefronts. The content presented was much like Wired magazine but for learning to design web content. Webmonkey had content applicable to both advanced users and newer internet users interested in the underlying technologies of the web.
History
Webmonkey was launched in August 1996.
In 1999, Webmonkey introduced Webmonkey Kids, a web design tutorial site for children.
Webmonkey was shut down in February 2004 following a round of layoffs in the U.S. division of its parent company, Lycos. It was reopened in February 2006, and mothballed again later in 2006.
In May 2008, Webmonkey was acquired by Condé Nast Publications, the company that publishes Wired magazine. It was temporarily relaunched as a wiki, but reconverted due to spam issues. Instead, the Webmonkey website was regularly updated with new articles by Scott Gilbertson until May 2013, when it was decided to stop producing content for it. The webmonkey URL was redirected to wired.com.

https://en.wikipedia.org/wiki/Teklogix | Teklogix International Inc., or Teklogix, was a tech company founded in 1967 by engineers working at Ferranti-Packard. The company focused on mini computer applications. It designed and built complete systems based upon DEC's PDP-8 computer, DEC's logic modules and purpose built logic. Many of the company's projects involved control of material handling systems and this led to the development of radio linked terminals for installation on fork lift trucks complete with multiplexers to interface to a variety of main frame computer systems.
In September 2000 Teklogix was acquired by U.K.-based Psion PLC, and became Psion Teklogix Inc.
Founders
The founders are: Rod Coutts, Lawrie Cragg, Al Vanderburgh, Cliff Bernard and Pete Halsall. Lawrie Cragg ran the company as President for the first nine years of its life.
The group met while working at Ferranti International's Canadian division, Ferranti-Packard Electronics. The engineers worked on projects related to FP6000 (Ferranti-Packard 6000, which became the ICL 1900), ReserVec, Back Up Interceptor Control (BUIC) for the United States Military, as well as Ferranti-Packard's drum memory systems. The group left Ferranti-Packard and formed Teklogix.
The founding members managed to collect $10,000 in initial subscribed capital, with an additional $8,000 provided by Pete Halsall, when he was made a full partner in the early 70's.
In the year 2000, the company was purchased by Psion for £240 million, or $544 million (CDN).
History
On September 20, 1967, Teklogix was formed by a group of five engineers. The first contract came from I. P. Sharp Associates (another Ferranti offspring) that involved the interface of a DEC PDP-8 computer to an X-ray spectrometer. The system controlled reagent feeders in a copper and zinc flotation mill. The objective was to analyze the mine head (i.e. what was coming out of the mine) using on-line X-ray spectroscopy and, then, using mathematical algorithms developed by University of Toronto, add the appropriate amounts of reagent to optimize mineral recovery.
In 1972, Teklogix was awarded a contract from Canada Post to control a tilt-tray mail sorter system. The company went on to be a primary supplier of sortation and conveyor control systems for the next decade.
In 1980, Teklogix introduced wireless real-time data collection solutions.
In 1981, the company was awarded a contract with U.S. Defense General Supply Agency (DGSC) to develop a real-time on-board pick information system for 37 Raymond pick vehicles. The next few years attracted more high-profile clients, such as General Motors, Digital Equipment Corp., General Dynamics, Avon and Owens Corning.
1988 - Teklogix opened its first U.S. office in Florence, Kentucky.1992 - Teklogix was expanded to Europe and Pacific Rim. In the summer of 1992, Teklogix produced its 10,000th terminal.1993 - An executive, principal engineers, and several other Teklogix employees resign and start a competing company, WaveLink Tech |

The Village Barn nightclub
The Village Barn, which later became the Generation Club and then was sold to Jimi Hendrix and remodelled into Electric Lady Recording Studios, was opened in November 1930 by owner Meyer Horowitz, who resigned as president and director on October 19, 1951. He was succeeded by his brother, Lawrence (Horowitz) Horton, who subsequently left to pursue other interests. Ownership remained with family members, including Horton, who returned to active management in the early 1960s; a nephew, George Goodman; and son Michael. Meyer Horowitz remained active as a consultant until the Barn closed in August 1967.
In 1931, Rudy Vallée, who had a nearby club, Villa Vallée, discovered Judy Canova at the Barn. Don Cornell, the Hartmans and other stars also got their start at the club.

https://en.wikipedia.org/wiki/Odenplan%20station | Odenplan station is a station on both the Green Line of the Stockholm Metro and the City Line of the Pendeltåg commuter rail network. It is located at Odenplan in Vasastaden, in Stockholm city centre.
The station was inaugurated on 26 October 1952 as a part of the stretch of the Metro between Hötorget and Vällingby. It was significantly expanded in July 2017, with the opening of the City Line that provided a dedicated north–south route for the Pendeltåg, serving Odenplan on the way. Besides the new tunnels and platforms for the City Line, new station entrances were constructed, supplementing those built for the Metro.
The station has two underground island platforms at different levels and on different alignments, with the City Line platforms at the lower level. It has entrances on Odenplan itself, on the north side of Karlbergsvägen opposite Odenplan, at the junction of Karlbergsvägen with Västmannagatan, and at the junction of Vanadisvägen with Dalagaten. The first two entrances provide direct access to both sets of platforms, whilst the Västmannagatan entrance provides direct access to the Metro platforms and Vanadisvägen to the City Line platforms. However both sets of platforms are connected by interchange passages, so it is possible to reach any platform from any entrance. Unlike the Metro platforms, the City Line platforms have platform screen doors.
The new entrance constructed on Odenplan for the opening of the City Line consists of a rectangular building that is approximately long, wide and high, with one long side facing Karlbergsvägen. The other long side bends gently inwards where stairwells form seats towards the square in the best sun position. The entrance building has five entrances and leads via escalators, ordinary stairs and an elevator down to the new ticket hall. Nearby is a new bicycle garage with a capacity of 350 bicycles.
Future plans include a diversion of the Roslagsbanan narrow-gauge commuter railway in tunnel from Universitetet station via Odenplan to a terminus at T-Centralen.
The station is 3.4 km from Slussen.

https://en.wikipedia.org/wiki/Cin%C3%A9%20First | Ciné First was a French television channel, part of the AB Groupe which shows exclusive films, oriented towards an adult audience.
The channel was broadcast on satellite networks Bis Télévisions and AB Groupe. It was also available via ADSL operator Free. The channel occupied the same position as the defunct Cinébox, which broadcast between September 2002 and August 2004.
History
On December 31, 2007, AB Groupe decided to create Ciné Pop for the family and Ciné First to strengthen the cinema offering of the Bis Télévisions satellite package. This one resumed the same dressing and the same thematic positioning as the defunct Ciné Box.
Nevertheless, the channel stopped on various operators on 31 August 2010, with the exception of a few broadcasting the channel until 30 September 2010, since the channel had been abolished because AB Groupe needed space on its transponders to broadcast its new sports channels Golf Channel and Lucky Jack TV on its bouquet.

https://en.wikipedia.org/wiki/Camera%20Headlines | Camera Headlines was an early American television series that aired from January 1948 to 1949 on the DuMont Television Network.
Broadcast history
DuMont's previous national news program, The Walter Compton News, had premiered on DuMont station WTTG in June 1947, then on the DuMont network on August 25, 1947, but was off the air by January 1948. This show had movie publicist Compton (1912-1959) reading news from a script with the occasional use of slides.
Premiering in January 1948, Camera Headlines was an attempt by DuMont to present a TV news program using newsreel film footage. As with some other early television programs, there is conflicting information about the show, with some sources reporting that the series was 30 minutes long, while other sources stating it was 15 minutes long. Camera Headlines aired Monday through Friday at 7:30 pm Eastern Time, with I.N.S. Telenews following at 7:45pm on Tuesdays only.
Camera Headlines also aired weekdays 12:30 to 12:45pm ET. The DuMont daytime schedule beginning in January 1949 was:
10-10:30am Johnny Olson's Rumpus Room
10:30-11am Welcome, Neighbors
11am-12noon The Stan Shaw Show
12noon-12:15pm Amanda
12:15-12:30pm Man in the Street
12:30-12:45pm Camera Headlines
12:45-1pm Fashions in Song
1-1:30pm Okay, Mother
2:30-3pm Inside Photoplay (The Wendy Barrie Show)
3-3:15pm The Needle Shop
3:15-3:30pm Vincent Lopez Speaking (The Vincent Lopez Show)
Episode status
As with most DuMont programs, no episodes of Camera Headlines are known to survive. Little else is known about the series, even though it aired on a major United States television network.

https://en.wikipedia.org/wiki/I.N.S.%20Telenews | I.N.S. Telenews was an American news program aired on the now defunct DuMont Television Network from 1948 to 1949.
Broadcast history
Each episode was 15 minutes long, made by International News Service, and aired weekly, each Tuesday at 7:45 pm EST, immediately following Camera Headlines which aired Monday through Friday at 7:30pm. As its name indicated, its main source of news information was the International News Service.
DuMont had aired The Walter Compton News, first as a local show on WTTG on June 16, 1947, then on the DuMont network from August 25, 1947, until January 1948, at which point DuMont replaced Compton's newscast with I.N.S. Telenews and Camera Headlines. After the two shows' cancellation in 1949, DuMont would not return to a network newscast until The DuMont Evening News was launched in 1954.
Episode status
No recordings of I.N.S. Telenews are known to survive.
The UCLA Film and Television Archive has earlier Hearst newsreel series, such as Hearst Metrotone News and News of the Day, and a later series of Hearst newsreels syndicated to television called Telenews (1954-1962). Possibly some episodes of I.N.S. Telenews exist in these other collections. (Note: A Telenews item can be found on YouTube under the title "NHL 52-53 First Beliveau's game for Habs".)

https://en.wikipedia.org/wiki/The%20Ted%20Steele%20Show | The Ted Steele Show is the title of several television and radio programs that were hosted by bandleader Ted Steele (1917–1985).
Television
Steele's programs were broadcast on three networks in three consecutive seasons: NBC September 29, 1948 - October 29, 1948; DuMont February 27, 1949 - July 12, 1949; CBS June 6, 1949 - April 28, 1950. The NBC and CBS programs were 15 minutes long, while those on DuMont were 30 minutes.
Other regular performers on the program included Helen Wood, Michael Rich, Nola Day, Marci Bryant and Charles Danford.
Steele later presented local daytime TV shows under the same title, running from 2:30 to 5:30 p.m. ET, on WPIX-TV and WOR-TV, which hired Steele away from WPIX in July 1954. The WPIX program was described in Billboard as "Live talent show, with Steele vocalizing and performing on several instruments, ork [orchestra] numbers, guests, news and sports round-ups, contest gimmicks."
Episode status
The final DuMont episode (July 12, 1949) is in the collection of the UCLA Film and Television Archive.
Radio
The Ted Steele Show was the title of a program Steele had on the Blue Network in 1942. A review in Billboard'''s January 31, 1942, issue indicated that the 30-minute show featured a singing group and a "playet" by a guest in addition to Steel's performances. He also did the Ted Steele Show on Mutual in the mid-1950s.
In the late 1940s, Steele had a disc jockey program, The Ted Steele Show, on WMCA in New York City. In 1940, he had a program with just his own name as the title, Ted Steele, on WFIL in Philadelphia, Pennsylvania. On that program, Steele played a Novachord synthesizer "as he kept up an entertaining stream of chatter."

https://en.wikipedia.org/wiki/Tales%20of%20the%20Red%20Caboose | Tales of the Red Caboose was a short-lived primetime television series that aired on the American Broadcasting Company television network, premiering October 29, 1948 and running until January 14, 1949.
Production background
The series was very basic television, consisting of a small children's model trains going around various tracks. It was, in a sense, an early infomercial, as it was sponsored by Lionel Trains.
The series was a complete failure, resulting in its quick cancellation after less than three months. The narrator, Don Magee, would tell stories about trains to accompany the visuals. The 15-minute show aired Fridays at 7:30pm ET.
Preservation status
No recordings of the program are known to survive.

https://en.wikipedia.org/wiki/Partly%20Cloudy | Partly Cloudy is a 2009 American computer-animated comedy short film, written and directed by Peter Sohn and produced by Kevin Reher. It was shown in theaters before Pixar's feature film Up and is a special feature on its DVD and Blu-ray release. It was included in the Animation Show of Shows in 2009.
In a CGSociety article, Sohn says his idea for the film came from watching Dumbo as a child: in the movie, a stork delivers Dumbo, leading a young Sohn to wonder where the birds got their babies from. His conclusion was that the babies came from clouds, hence flying animals being needed to deliver them.
Plot
All day long, cheerful clouds in the sky make cute and cuddly babies, such as human boys and girls, kittens, puppies, and other creatures, and give them to storks for delivery to the expectant parents. However, one lonely gray cloud named Gus has the task of creating animals that are cute but not so cuddly. His delivery stork, Peck, gets the worst of it, being bitten by a crocodile, butted by a bighorn sheep, and pricked by a porcupine. When Peck sees that his next delivery is a baby shark, he grows more than a little fearful and flies away.
Feeling rejected, despondent, and angry, Gus unleashes a brief thunderstorm, then starts crying with rain pouring from below him. Peck, however, soon returns with a football helmet and shoulder pads, created for him by another cloud to keep him safe (alluded to in an earlier scene, where the same cloud creates a baby that would grow to love football). Gus instantly cheers up and gives Peck an electric eel to deliver, which shocks him despite the protective equipment; this time, though, Peck remains in good (but slightly frazzled) spirits.

https://en.wikipedia.org/wiki/What%27s%20It%20Worth | What's It Worth is an early American television series that aired on the CBS Television network from 21 May 1948 and into 1949. The series was later revived in 1952, before finally finishing its run on 11 October 1953.
The show was hosted by self-taught appraiser Sigmund Rothschild (1917-1991), who appraised antiques for celebrities. Rothschild also hosted a similar program called Trash or Treasure? (1952–53) on the DuMont Television Network.
As the series title suggests, the audience submitted items of art, and Rothschild would tell them how much they were worth.

https://en.wikipedia.org/wiki/Building%2026 | "Building 26" is the sixteenth episode of the third season of the superhero drama series Heroes and fiftieth episode overall. The episode aired on February 16, 2009 on the NBC network in the United States, its country of origin. The episode was written by Rob Fresco and was directed by Sergio Mimica-Gezzan.
The episode was split up between four stories and kept going back and forth between them. The four stories are; Hiro Nakamura (Masi Oka) and Ando Masahashi (James Kyson Lee) in India trying to stop a wedding as per Matt Parkman's precognition drawings from the previous episode. Nathan Petrelli (Adrian Pasdar) at his campaign office trying to stop a new character, his new boss Abby (Moira Kelly), from shutting down his entire operation of rounding up all the humans with special abilities. Sylar (Zachary Quinto) and Luke Campbell (Dan Byrd) travelling on the road to find Sylar's birth father. The Bennet family's tension of relationship with one another while Claire Bennet (Hayden Panettiere) reads text messages from a mysterious character known only as "Rebel".
Plot
Matt Parkman's prophetic images from the previous episode leads Hiro Nakamura and Ando Masahashi to India to stop a wedding from taking place. The bride, Annapurna, is upset as she truly does not love the groom, Deepak, and is being forced into the wedding. Hiro becomes jealous of Ando, who talks to Annapurna and becomes the hero by making her call off the wedding. Afterwards, a furious Deepak kidnaps Ando and makes the wedding go ahead as planned. By the end of the episode, the wedding is in full swing when Hiro manages to stop the wedding, and get Ando back. Hiro discerns that the trip to India was destined so that he realizes that he can be the Hero without having special abilities. Near the end of the episode, the two receive a fax from the mysterious "Rebel", the same name that has been contacting Claire Bennet. The fax tells Hiro and Ando that they need to save Matt Parkman.
Meanwhile, Nathan Petrelli seeks more funding but finds trouble when his new boss, Abby (Moira Kelly), gets sent to investigate what he has been doing. She finds Tracy Strauss in captivity and orders Nathan to shut down the entire operation. Abby's mind drastically changes however when she sees Tracy escape and freeze a man to death, before being put back in her cell. Abby states that he can have all the funding he needs. Tracy believes that Nathan left the door unlocked and weakened the chains so she could escape for Abby to see the truth about the whole operation, and further warns Nathan she will inevitably escape. Nathan and Danko both know however that Danko had schemed the whole thing behind Nathan's back.
Sylar and Luke Campbell are heading west to find Sylar's birth parents. Tension increases between them as Luke tries to befriend Sylar, but they soon stop at a diner to refuel and get something to eat. Sylar states that recently his only desire is to find his birth father. Luke gives Sylar the |
https://en.wikipedia.org/wiki/Make%20Compatible | Make Compatible is a program developed by Microsoft that is included with Windows 9x operating systems. It changes per-program system settings in Windows to allow Windows 3.1 programs that are tailored specifically to that platform to execute under newer versions. The name of the program image file for Make Compatible is , and it is stored in the directory.
Options
When it is invoked, one can choose the name of the Windows 3.1 application program image file using the "Choose Program" option on the "File" menu. After the program image file is chosen, Make Compatible by default displays a list of five options that can be set to alter the behaviour of Windows for that program when it is executed:
Don't spool to enhanced meta files
Give application more stack space
Lie about printer device mode size
Lie about Windows version number
Windows 3.1-style controls
An advanced options mode, selectable via the "Advanced Options" selection on the "File" menu presents a longer list of options, allowing finer control of Windows 3.1 emulation if the particular application requires it.
Compatibility bits
Each of the options is recorded in a system database of so-called "compatibility bits". This is a database of 1-bit flags, one for each of the options displayed by Make Compatible.
This database already existed in earlier versions of Windows. In Windows 3.1, the database is stored in the section of , with entries such as:
[Compatibility]
ACAD=0x8000
AMIPRO=0x04000010
Each line names an application program, and gives a hexadecimal numeric constant to associate with that program. The hexadecimal numeric constant encodes the compatibility bitflags for that particular application, that Windows applies when the application is executed. Make Compatible merely provides a graphical user interface for editing these flags in an easy way, rather than editing manually, with a text editor. It allows one to set and unset individual flags without having to know their numeric values.
The compatibility bitflags settable in are not documented in the file that ships with Windows 3.1, or in the Microsoft Windows 3.1 Resource Kit published by Microsoft. They are listed as a simple set of defined constants (with names beginning "GACF_" for "GetAppCompatFlags"), without explanation, in the header file that is shipped with the Microsoft Windows 3.1 Device driver Development Kit. In Windows 3.1, the compatibility flags that are in effect for any given task in the kernel's Task Database are readable via the undocumented GetAppCompatFlags() function that is exported from the module.
Advanced mode flags
The flags are documented in Microsoft KnowledgeBase article #82860. They correspond to the "advanced mode" flags that are settable by Make Compatible's "Advanced Options" menu:

https://en.wikipedia.org/wiki/Cimatron | Cimatron is an Israeli software company that produces CAD/CAM software for manufacturing, toolmaking and CNC programming applications.
The company was listed on the Nasdaq exchange under the symbol CIMT, until its 2014 acquisition by 3D Systems. Prior to this, the company's major shareholder was DBSI, whose co-managing partner, Yossi Ben-Shalom, chaired the Cimatron board.
Headquartered in Tel Aviv, the company had subsidiaries in the United States, Germany, Italy, China, South Korea, India and Brazil, as well as resellers in over 40 countries. Its main software products, CimatronE and GibbsCAM, continue to be used in over 40,000 installations worldwide. Its clients are largely from the automotive, aerospace, consumer electronics, toys, medical, optics and telecom industries.
One of the company's major clients is China's Haier Mould, a subsidiary of the Haier Group.
History
The company was founded in 1982 as MicroCAD, releasing its first software products Multicadd and Multicam in 1984 for use by small- to medium-sized tool shops. In 1987 the company changed its name to Cimatron.
In 1990, the company launched Cimatron IT, which it claimed was the world's first integrated CAD/CAM software.
In March 1996, Cimatron began trading on the Nasdaq under the symbol CIMT. In 1999 Cimatron launched its product for Windows, CimatronE. In March 2011, Cimatron began trading on the Tel-Aviv Stock Exchange, becoming a dual-listed company. However, in 2013 its board of directors voted to delist from the TASE.
In July 2005, Cimatron acquired an initial 27.5% interest in Microsystem Srl, its Italian distributor. By July 2008, Cimatron had completed the acquisition of 100% of Microsystem.
In January 2008, Cimatron merged with US CNC machining software company Gibbs and Associates. Former Gibbs head William Gibbs assumed the position of Cimatron President North America and Vice Chairman of Cimatron Ltd. and agreed to remain with the company for at least five years.
In 2010, Cimatron was listed by PLM consulting firm CIMdata as one of the leading suppliers of CAM software based on CAM software and services direct revenue received. CIMdata also predicted that Cimatron would be one of the five most rapidly growing CAM software companies in 2011.
In the 4th quarter of 2010, Cimatron reported its highest ever quarterly revenue of $11 million and operating profit of $1.7 million. Also Cimatron and LEDAS (LGS 3D owner those days) have collaborated on Motion Simulation application dedicated to mold, tool and die maker design, that is able to work with standard CAD shapes, i.e. canonics and NURBS. Collision detection was based on functions of ACIS kernel, while motion itself was performed by LGS 3D as a sequence of constraint satisfaction problems. As a result of collaboration, Cimatron licensed LGS 3D, and Motion Simulation application was developed and integrated into CimatronE CAM system.
In 2011, the company was listed as one of Israel's fastest growing techno |
https://en.wikipedia.org/wiki/RAM%20limit | The maximum random access memory (RAM) installed in any computer system is limited by hardware, software and economic factors. The hardware may have a limited number of address bus bits, limited by the processor package or design of the system. Some of the address space may be shared between RAM, peripherals, and read-only memory. In the case of a microcontroller with no external RAM, the size of the RAM array is limited by the size of the integrated circuit die. In a packaged system, only enough RAM may be provided for the system's required functions, with no provision for addition of memory after manufacture.
Software limitations to usable physical RAM may be present. An operating system may only be designed to allocate a certain amount of memory, with upper address bits reserved to indicate designations such as I/O or supervisor mode or other security information. Or the operating system may rely on internal data structures with fixed limits for addressable memory.
For mass-market personal computers, there may be no financial advantage to a manufacturer in providing more memory sockets, address lines, or other hardware than necessary to run mass-market software. When memory devices were relatively expensive compared with the processor, often the RAM delivered with the system was much less than the address capacity of the hardware, because of cost.
Sometimes RAM limits can be overcome using special techniques. Bank switching allows blocks of RAM memory to be switched into the processor's address space when required, under program control. Operating systems routinely manage running programs using virtual memory, where individual program operate as if they have access to a large memory space that is being simulated by swapping memory areas with disk storage.
CPU addressing limits
For performance reasons, all the parallel address lines of an address bus must be valid at the same time, otherwise access to memory would be delayed and performance would be seriously reduced. Integrated circuit packages may have a limit on the number of pins available to provide the memory bus. Different versions of a CPU architecture, in different-sized IC packages, can be designed, trading off reduced package size for reduced pin count and address space. A trade-off might be made between address pins and other functions, restricting the memory physically available to an architecture even if it inherently has a higher capacity. On the other hand, segmented or bank switching designs provide more memory address space than is available in an internal memory address register.
As integrated circuit memory became less costly, it was feasible to design systems with larger and larger physical memory spaces.
Fewer than 16 address pins
Microcontroller devices with integrated I/O and memory on-chip sometimes had no, or a small, address bus available for external devices. For example, a microcontroller family available with a 2 kilobyte address space might have a variant t |

https://en.wikipedia.org/wiki/Information%20visualization%20reference%20model | The Information visualization reference model is an example of a reference model for information visualization, developed by Ed Chi in 1999, under the name of the data state model. Chi showed that the framework successfully modeled a wide array of visualization applications and later showed that the model was functionally equivalent to the data flow model used in existing graphics toolkits such as VTK.
Overview
In previous work, according to Chi (2000), "researchers have attempted to construct taxonomies of information visualization techniques by examining the data domains that are compatible with these techniques. This is useful because implementers can quickly identify various techniques that can be applied to their domain of interest. However, these taxonomies do not help the implementers understand how to apply and implement these techniques".
According to Chi (2000), he and J.T. Reidl "in 1998 extends and proposes a new way to taxonomize information visualization techniques by using the Data State Model. Many of the techniques share similar operating steps that can easily be reused. The Data State Model not only helps researchers understand the space of design, but also helps implementers understand how information visualization techniques can be applied more broadly".
In 1999 Stuart Card, Jock D. Mackinlay, and Ben Shneiderman present their own interpretation of this pattern, dubbing it the information visualization reference model.

https://en.wikipedia.org/wiki/Matrix%20multiplication%20algorithm | Because matrix multiplication is such a central operation in many numerical algorithms, much work has been invested in making matrix multiplication algorithms efficient. Applications of matrix multiplication in computational problems are found in many fields including scientific computing and pattern recognition and in seemingly unrelated problems such as counting the paths through a graph. Many different algorithms have been designed for multiplying matrices on different types of hardware, including parallel and distributed systems, where the computational work is spread over multiple processors (perhaps over a network).
Directly applying the mathematical definition of matrix multiplication gives an algorithm that takes time on the order of field operations to multiply two matrices over that field ( in big O notation). Better asymptotic bounds on the time required to multiply matrices have been known since the Strassen's algorithm in the 1960s, but the optimal time (that is, the computational complexity of matrix multiplication) remains unknown. , the best announced bound on the asymptotic complexity of a matrix multiplication algorithm is time, given by Duan, Wu and Zhou announced in a preprint. This improves on the bound of time, given by Josh Alman and Virginia Vassilevska Williams. However, this algorithm is a galactic algorithm because of the large constants and cannot be realized practically.
Iterative algorithm
The definition of matrix multiplication is that if for an matrix and an matrix , then is an matrix with entries
From this, a simple algorithm can be constructed which loops over the indices from 1 through and from 1 through , computing the above using a nested loop:
Input: matrices and
Let be a new matrix of the appropriate size
For from 1 to :

This algorithm takes time (in asymptotic notation). A common simplification for the purpose of algorithms analysis is to assume that the inputs are all square matrices of size , in which case the running time is , i.e., cubic in the size of the dimension.
Cache behavior
The three loops in iterative matrix multiplication can be arbitrarily swapped with each other without an effect on correctness or asymptotic running time. However, the order can have a considerable impact on practical performance due to the memory access patterns and cache use of the algorithm;
which order is best also depends on whether the matrices are stored in row-major order, column-major order, or a mix of both.
In particular, in the idealized case of a fully associative cache consisting of bytes and bytes per cache line (i.e. cache lines), the above algorithm is sub-optimal for and stored in row-major order. When , every iteration of the inner loop (a simultaneous sweep through a row of and a column of ) incurs a cache miss when accessing an element of . This means that the algorithm incurs cache misses in the worst case. |
https://en.wikipedia.org/wiki/Hyper%20CD-ROM | The Hyper CD-ROM is a claimed optical data storage device similar to the CD-ROM with a multilayer 3D structure, invented by Romanian scientist Eugen Pavel.
The technology is supposedly similar to FMD discs. The bit of data being held as a change in fluorescence characteristics once irradiated with one or two lasers. The target is irradiated with a pulse of laser(s) then a CCD or photodiode wait for an emitted light by the medium due to the Fluorescence effect (bit value set to "1" if emitted, else "0").
Characteristics
The reported storage capacity of one such disk is as storage occurs on levels layered inside the glass body of the disk.
It claims to use fluorescent photosensitive material (glass enhanced with rare earth or vitroceramic enhanced with photosensitizing metals) as storage medium.
The Hyper CD-ROM technology is patented in 21 countries: the US, Canada, Japan, Israel and 17 European states.
Despite its bold claims the technology has not been shown as a working prototype in the over twenty years since its announcement and there has been no commercial production.
In an interview about his work on the Hyper CD-ROM, Pavel stated that "the research for this project is 100% personal, [and] so is the support for experiments."
