21Coupled map lattice — A coupled map lattice (CML) is a dynamical system that models the behavior of non linear systems (especially partial differential equations). They are predominantly used to qualitatively study the chaotic dynamics of spatially extended systems.… …
22Born-Oppenheimer approximation — In quantum chemistry, the computation of the energy and wavefunction of an average size molecule is a formidable task that is alleviated by the Born Oppenheimer (BO) approximation. For instance the benzene molecule consists of 12 nuclei and 42… …
23Yukawa potential — A Yukawa potential (also called a screened Coulomb potential) is a potential of the form:V(r)= g^2 ;frac{e^{ mr{r}Hideki Yukawa showed in the 1930s that such a potential arises from the exchange of a massive scalar field such as the field of the… …
24Degrees of freedom (physics and chemistry) — A degree of freedom is an independent physical parameter, often called a dimension, in the formal description of the state of a physical system. The set of all dimensions of a system is known as a phase space. Contents 1 Definition 2 Example:… …
25Pulse-coupled networks — or Pulse Coupled Neural Networks (PCNNs) are neural models proposed by modeling a cat’s visual cortex and developed for high performance biomimetic image processing. In 1989, Eckhorn introduced a neural model to emulate the mechanism of cat’s… …
26Acoplamiento de momento angular — En mecánica cuántica, el procedimiento de construir estados propios del momento angular total (estados de un sistema con valores bien definidos del momento angular) a partir de los estados propios de los momentos angulares individuales se llama… …
27Four-wheel drive — This article is about the class of vehicle drivetrains. For other uses, see Four by four/Four wheel drive (disambiguation). All wheel drive redirects here. For the all wheel drive in motorcycles, see two wheel drive. The Jeep Wrangler is a 4WD… …
28Glossary of firefighting equipment — Note: This list is incomplete. You can help Wikipedia by [http://en.wikipedia.org/w/index.php?title=Glossary of firefighting equipment action=edit adding to it] . 0 9 * 1 3/4 inch hose: see attack hose * 2 1/2 inch hose: see attack hose , supply… …
29Ising model — The Ising model, named after the physicist Ernst Ising, is a mathematical model in statistical mechanics. It has since been used to model diverse phenomena in which bits of information, interacting in pairs, produce collectiveeffects.Definition… …
30Output transformerless — (OTL) is a term which describes a subset of vacuum tube audio power amplifier topologies, all of which omit an output transformer for the purpose of greater linearity and fidelity. Conventional vacuum tube amplifier designs rely upon an output… …
