121Radar tracker — A radar tracker is a component of a radar system, or an associated command and control (C2) system, that associates consecutive radar observations of the same target into tracks. It is particularly useful when the radar system is reporting data… …
122Homology modeling — Homology modeling, also known as comparative modeling of protein refers to constructing an atomic resolution model of the target protein from its amino acid sequence and an experimental three dimensional structure of a related homologous protein… …
123Item response theory — In psychometrics, item response theory (IRT) is a body of theory describing the application of mathematical models to data from questionnaires and tests as a basis for measuring abilities, attitudes, or other variables. It is used for statistical …
124Robust statistics — provides an alternative approach to classical statistical methods. The motivation is to produce estimators that are not unduly affected by small departures from model assumptions. Contents 1 Introduction 2 Examples of robust and non robust… …
125Uncertainty principle — In quantum physics, the Heisenberg uncertainty principle states that locating a particle in a small region of space makes the momentum of the particle uncertain; and conversely, that measuring the momentum of a particle precisely makes the… …
126Cost-benefit analysis — is a term that refers both to:* a formal discipline used to help appraise, or assess, the case for a project or proposal, which itself is a process known as project appraisal; and * an informal approach to making decisions of any kind. Under both …
127Computer simulation — This article is about computer model within a scientific context. For artistic usage, see 3d modeling. For simulating a computer on a computer, see emulator. A 48 hour computer simulation of Typhoon Mawar using the Weather Research and… …
128Population viability analysis — (PVA) is a species specific method of risk assessment frequently used in conservation biology. It is traditionally defined as the process that determines the probability that a population will go extinct within a given number of years. More… …
