https://en.wikipedia.org/wiki/Instruction%20path%20length | In computer performance, the instruction path length is the number of machine code instructions required to execute a section of a computer program. The total path length for the entire program could be deemed a measure of the algorithm's performance on a particular computer hardware. The path length of a simple condit... |
https://en.wikipedia.org/wiki/Computer%20keyboard | A computer keyboard is a peripheral input device modeled after the typewriter keyboard which uses an arrangement of buttons or keys to act as mechanical levers or electronic switches. Replacing early punched cards and paper tape technology, interaction via teleprinter-style keyboards have been the main input method for... |
https://en.wikipedia.org/wiki/Synthetic%20genetic%20array | Synthetic genetic array analysis (SGA) is a high-throughput technique for exploring synthetic lethal and synthetic sick genetic interactions (SSL). SGA allows for the systematic construction of double mutants using a combination of recombinant genetic techniques, mating and selection steps. Using SGA methodology a quer... |
https://en.wikipedia.org/wiki/Synthetic%20lethality | Synthetic lethality is defined as a type of genetic interaction where the combination of two genetic events results in cell death or death of an organism. Although the foregoing explanation is wider than this, it is common when referring to synthetic lethality to mean the situation arising by virtue of a combination of... |
https://en.wikipedia.org/wiki/SVI-838 | The SVI-838, also known as X'press 16, is the last microcomputer produced by Spectravideo (at Hong Kong). Although it was a PC clone, it had the standard sound and video coprocessors of the MSX2, making it a hybrid system. The sales were unimpressive and it is now considered a collectible.
With a SVI-811 adapter, the ... |
https://en.wikipedia.org/wiki/BioPAX | BioPAX (Biological Pathway Exchange) is a RDF/OWL-based
standard language to represent biological pathways at the molecular and cellular level. Its major use is to facilitate the exchange of pathway data. Pathway data captures our understanding of biological processes, but
its rapid growth necessitates development of d... |
https://en.wikipedia.org/wiki/Journal%20of%20Green%20Building | The Journal of Green Building is a quarterly peer-reviewed academic journal covering research on green buildings, applications, techniques, and processes. It was established in 2006 and the editor-in-chief is Steffen Lehmann (University of South Australia). The journal is abstracted and indexed in the Arts & Humanities... |
https://en.wikipedia.org/wiki/Adriano%20Garsia | Adriano Mario Garsia (born 20 August 1928) is a Tunisian-born Italian American mathematician who works in analysis, combinatorics, representation theory, and algebraic geometry. He is a student of Charles Loewner and has published work on representation theory, symmetric functions, and algebraic combinatorics. He and M... |
https://en.wikipedia.org/wiki/Virtual%20Socket%20Interface%20Alliance | Virtual Socket Interface Alliance (VSIA) is a body of SIP (Semiconductor / Silicon intellectual property) standards.
History
VSIA was founded in 1996 and dissolved in 2008, and was an open, international organization of companies such as Mentor Graphics, Cadence Design Systems, Magma Design Automation, ARM Holdings, ... |
https://en.wikipedia.org/wiki/Coordinate-free | A coordinate-free, or component-free, treatment of a scientific theory or mathematical topic develops its concepts on any form of manifold without reference to any particular coordinate system.
Benefits
Coordinate-free treatments generally allow for simpler systems of equations and inherently constrain certain types o... |
https://en.wikipedia.org/wiki/Constant%20current | A constant current (steady current, time-independent current, stationary current) is a type of direct current (DC) that does not change its intensity with time.
Sources
If the load is constant, a steady current can be obtained via a constant voltage source. If the load is varying, a steady current can be obtained vi... |
https://en.wikipedia.org/wiki/Software%20ecosystem | Software Ecosystem is a book written by David G. Messerschmitt and Clemens Szyperski that explains the essence and effects of a "software ecosystem", defined as a set of businesses functioning as a unit and interacting with a shared market for software and services, together with relationships among them. These relatio... |
https://en.wikipedia.org/wiki/Continuous%20emissions%20monitoring%20system | Continuous emission monitoring systems (CEMS) are used as a tool to monitor the effluent gas streams resulting from combustion in industrial processes. CEMS can measure flue gas for oxygen, carbon monoxide and carbon dioxide to provide information for combustion control in industrial settings. They are also used as a m... |
