Phase line — In mathematics, a phase line is a diagram which shows the behaviour of an autonomous ordinary differential equation. The term is also used in histogeographic maps and military maps to show some positional dependency or relation to the passage of… … Wikipedia
Phase portrait — A phase portrait is a geometric representation of the trajectories of a dynamical system in the phase plane. Each set of initial conditions is representated by a different curve, or point.Phase portraits are an invaluable tool in studying… … Wikipedia
Phase plane — A phase plane is a visual display of certain characteristics of certain kinds of differential equations.Certain systems of differential equations can be written in the form::dx/dt = Cx where C may be any combination of constants in order to… … Wikipedia
Minimum phase — In control theory and signal processing, a linear, time invariant system is said to be minimum phase if the system and its inverse are causal and stable.[1][2] For example, a discrete time system with rational transfer function H(z) can only… … Wikipedia
Three phase traffic theory — The three phase traffic theory is an alternative traffic theory developed by Boris Kerner. It is mainly concerned with the physics of traffic congestion at freeways. Kerner describes three phases, opposed to the classical theories based on the… … Wikipedia
Two-phase flow — In fluid mechanics, two phase flow occurs in a system containing gas and liquid with a meniscus separating the two phases. Historically, probably the most commonly studied cases of two phase flow are in large scale power systems. Coal and gas… … Wikipedia
