variation of parameters
11Packet delay variation — In computer networking, packet delay variation (PDV) is the difference in end to end delay between selected packets in a flow with any lost packets being ignored (RFC 3393).[1] The effect is sometimes referred to as jitter, although the… …
12Explained variation — In statistics, explained variation or explained randomness measures the proportion to which a mathematical model accounts for the variation (= apparent randomness) of a given data set. Often, variation is quantified as variance; then, the more… …
13Matrix exponential — In mathematics, the matrix exponential is a matrix function on square matrices analogous to the ordinary exponential function. Abstractly, the matrix exponential gives the connection between a matrix Lie algebra and the corresponding Lie group.… …
14Parametric oscillator — A parametric oscillator is a simple harmonic oscillator whose parameters (its resonance frequency omega and damping eta) vary in time in a defined wayAnother intuitive way of understanding a parametric oscillator is as follows: a parametric… …
15Fuzzy locating system — Fuzzy locating is a rough but reliable method based on appropriate measuring technology for estimating a location of an object. The concept of precise or ‘’crisp locating’’ is replaced with respect to the operational requirements and the economic …
16Linear differential equation — In mathematics, a linear differential equation is a differential equation of the form: Ly = f ,where the differential operator L is a linear operator, y is the unknown function, and the right hand side fnof; is a given function (called the source …
17Serialism — In music, serialism is a technique for composition that uses sets to describe musical elements, and allows the manipulation of those sets.Fact|date=May 2008 Serialism is often, though not universally, held to begin with twelve tone technique,… …
18Rössler attractor — The Rössler attractor (pronEng|ˈrɒslɚFact|date=December 2007) is the attractor for the Rössler system, a system of three non linear ordinary differential equations. These differential equations define a continuous time dynamical system that… …
19Method of undetermined coefficients — In mathematics, the method of undetermined coefficients, also known as the lucky guess method, is an approach to finding a particular solution to certain inhomogeneous ordinary differential equations and recurrence relations. It is closely… …
