State space (controls) — In control engineering, a state space representation is a mathematical model of a physical system as a set of input, output and state variables related by first order differential equations. To abstract from the number of inputs, outputs and… … Wikipedia
State space (dynamical system) — In the theory of discrete dynamical systems, a state space is a directed graph where each possible state of a dynamical system is represented by a vertex, and there is a directed edge from a to b if and only if ƒ(a) = b where the… … Wikipedia
State space — In computer science, a state space is a description of a configuration of discrete states used as a simple model of machines. Formally, it can be defined as a tuple [N, A, S, G] where: * N is a set of states * A is a set of arcs connecting the… … Wikipedia
Space charge — is a concept in which excess electric charge is treated as a continuum of charge distributed over a region of space (either a volume or an area) rather than distinct point like charges. This model typically applies when charge carriers have been… … Wikipedia
space exploration — Investigation of the universe beyond Earth s atmosphere by means of manned and unmanned spacecraft. Study of the use of rockets for spaceflight began early in the 20th century. Germany s research on rocket propulsion in the 1930s led to… … Universalium
PHYSICS — The material presented in this entry emphasizes those contributions which were important in arriving at verified present day scientific results, rather than those that may have appeared important at the time. Unavoidably it will overlap in parts… … Encyclopedia of Judaism
State variable — A state variable is an element of the set of variables that describe the state of a dynamical system.In case of simple mechanical systems, position coordinates and their derivates are typical state variables. Temperature, pressure, internal… … Wikipedia
Physics — (Greek: physis φύσις), in everyday terms, is the science of matter [R. P. Feynman, R. B. Leighton, M. Sands (1963), The Feynman Lectures on Physics , ISBN 0 201 02116 1 Hard cover. p.1 1 Feynman begins with the atomic hypothesis.] and its motion … Wikipedia
Phase space — In mathematics and physics, a phase space, introduced by Willard Gibbs in 1901, is a space in which all possible states of a system are represented, with each possible state of the system corresponding to one unique point in the phase space. For… … Wikipedia
Space science — is an all encompassing term that describes all of the various science fields that are concerned with the study of the Universe, generally also meaning excluding the Earth and outside of the Earth s atmosphere . Originally, all of these fields… … Wikipedia
