Models of scientific inquiry — In the philosophy of science, models of scientific inquiry have two functions: first, to provide a descriptive account of how scientific inquiry is carried out in practice, and second, to provide an explanatory account of why scientific inquiry… … Wikipedia
Mathematical models in physics — Mathematical models are of great importance in physics. Physical theories are almost invariably expressed using mathematical models, and the mathematics involved is generally more complicated than in the other sciences. Different mathematical… … Wikipedia
Proportional hazards models — are a class of survival models in statistics. Survival models relate the time that passes before some event occurs to one or more covariates that may be associated with that quantity. In a proportional hazards model, the unique effect of a unit… … Wikipedia
Transistor models — Transistors are complicated devices. In order to ensure the reliable operation of circuits employing transistors, it is necessary to scientifically model the physical phenomena observed in their operation using transistor models. There exists a… … Wikipedia
Atmospheric models — Static atmospheric models describe how the ideal gas properties (namely: pressure, temperature, density, and molecular weight) of an atmosphere change, primarily as a function of altitude. For example, the US Standard Atmosphere is essentially a… … Wikipedia
Chi-squared target models — Swerling models were introduced by Peter Swerling and are used to describe the statistical properties of the radar cross section of complex objects. Contents 1 General Target Model 2 Swerling Target Models 2.1 Swerling I 2 … Wikipedia

QCD vacuum — The QCD vacuum is the vacuum state of quantum chromodynamics (QCD). It is an example of a non perturbative vacuum state, characterized by many non vanishing condensates such as the gluon condensate or the quark condensate. These condensates… … Wikipedia
Genetic algorithm — A genetic algorithm (GA) is a search heuristic that mimics the process of natural evolution. This heuristic is routinely used to generate useful solutions to optimization and search problems. Genetic algorithms belong to the larger class of… … Wikipedia
