The "Dialogue" does not treat the Tychonic system, which was becoming the preferred system of many astronomers at the time of publication and which was ultimately proven incorrect. The Tychonic system is a motionless Earth system but not a Ptolemaic system; it is a hybrid system of the Copernican and Ptolemaic models. ...

There have been several attempts to create methods and tools that can detect and observe biases within an algorithm. These emergent fields focus on tools which are typically applied to the (training) data used by the program rather than the algorithm's internal processes. These methods may also analyze a program's outp...

In an electrolytic cell, a current passes through the cell by an external voltage, causing a non-spontaneous chemical reaction to proceed. In a galvanic cell, the progress of a spontaneous chemical reaction causes an electric current to flow. An equilibrium electrochemical cell exists in the state between an electrolyt...

In quantum field theory, there exist quantum categories. and quantum double groupoids. One can consider quantum double groupoids to be fundamental groupoids defined via a 2-functor, which allows one to think about the physically interesting case of quantum fundamental groupoids (QFGs) in terms of the bicategory Span(Gr...

Due to a delay in the MICNS secure data link, the first prototype system was produced in a Block I configuration. This system used the same air vehicle (minus the MICNS and automated landing system), the same hydraulic launcher, the same hydraulically operated recovery system, and same Ground Control System. This syste...

A problem with solar cells is that the high energy photons that hit the surface are converted to heat. This is a loss for the cell because the incoming photons are not converted into usable energy. The idea behind the hot carrier cell is to utilize some of that incoming energy which is converted to heat. If the electro...

The quantum automaton differs from the topological automaton in that, instead of having a binary result (is the iterated point in, or not in, the final set?), one has a probability. The quantum probability is the (square of) the initial state projected onto some final state "P"; that is formula_108. But this probabilit...

The IBM System/38 was intended to be the successor of the System/34 and the earlier System/3x systems. However, due to the delays in the development of the System/38 and the high cost of the hardware once complete, IBM developed the simpler and cheaper System/36 platform which was more widely adopted than the System/38...

In machine learning, Manifold regularization is a technique for using the shape of a dataset to constrain the functions that should be learned on that dataset. In many machine learning problems, the data to be learned do not cover the entire input space. For example, a facial recognition system may not need to classify...

Kuṭṭaka is an algorithm for finding integer solutions of linear Diophantine equations. A linear Diophantine equation is an equation of the form "ax" + "by" = "c" where "x" and "y" are unknown quantities and "a", "b", and "c" are known quantities with integer values. The algorithm was originally invented by the Indian a...

The National Meteorological Center's Global Spectral Model was introduced during August 1980. The European Centre for Medium-Range Weather Forecasts model debuted on May 1, 1985. The United Kingdom Met Office has been running their global model since the late 1980s, adding a 3D-Var data assimilation scheme in mid-1999....

The third, SROSS 3 (also known as SROSS C), attained a lower-than-planned orbit on 20 May 1992. The GRB monitored celestial gamma ray bursts in the energy range 20–3000 keV. SROSS C and C2 carried a gamma-ray burst (GRB) experiment and a Retarded Potential Analyzer (RPA) experiment. The GRB experiment operated from 25 ...

Video modulation is a strategy of transmitting video signal in the field of radio modulation and television technology. This strategy enables the video signal to be transmitted more efficiently through long distances. In general, video modulation means that a higher frequency carrier wave is modified according to the o...

Chemical compatibility is important when choosing materials for chemical storage or reactions, so that the vessel and other apparatus will not be damaged by its contents. For purposes of chemical storage, chemicals that are incompatible should not be stored together so that any leak will not cause an even more dangerou...

A marathon runner's velocity at lactate threshold is strongly correlated to their performance. Lactate threshold or anaerobic threshold is considered a good indicator of the body's ability to efficiently process and transfer chemical energy into mechanical energy. A marathon is considered an aerobic dominant exercise, ...

QTT addresses the measurement problem in quantum mechanics by providing a detailed description of what happens during the so-called "collapse of the wave function". It reconciles the concept of a quantum jump with the smooth evolution described by the Schrödinger equation. The theory suggests that "quantum jumps" are n...

Algorithmic complexity is the rate in which an algorithm performs. Although there are multiple ways to solve a computational problem, the best and most effective way in doing so matters. All factors such as the hardware, networking, programming language, and performance constraints play into the time a program takes to...

Energy security measures center on reducing dependence on any one source of imported energy or supplier, exploiting renewable energy resources, and reducing demand by energy conservation. Finland is highly dependent on energy import from Russia: 71% of total energy in 2007: Hard coal 92%, raw oil 75% and natural gas 10...

For example, the politicians of Espoo sold the public district heating system for the big energy company Fortum in 2006. Since then the district heating prices in Espoo have kept rising and Espoo city has lost tens of millions of euros annually in the energy business compared to nearby cities Helsinki and Vantaa.

Scanning the photon energy corresponds to shifting the internal energy distribution of the parent ion. The parent ion sits in a potential energy well, in which the lowest energy exit channel often corresponds to the breaking of the weakest chemical bond, resulting in the formation of a fragment or daughter ion. A mass ...
