1Muffin-tin approximation — Electronic structure methods Tight binding Nearly free electron model Hartree–Fock method Modern valence bond Generalized valence bond Møller–Plesset perturbation theory …
2Info-gap decision theory — is a non probabilistic decision theory that seeks to optimize robustness to failure – or opportuneness for windfall – under severe uncertainty,[1][2] in particular applying sensitivity analysis of the stability radius type[3] to perturbations in… …
3Implicit solvation — (sometimes known as continuum solvation) is a method of representing solvent as a continuous medium instead of individual “explicit” solvent molecules most often used in molecular dynamics simulations and in other applications of molecular… …
4Friction — For other uses, see Friction (disambiguation). Classical mechanics …
5Mean field theory — (MFT, also known as self consistent field theory) is a method to analyse physical systems with multiple bodies. A many body system with interactions is generally very difficult to solve exactly, except for extremely simple cases (random field… …
6Orbital mechanics — A satellite orbiting the earth has a tangential velocity and an inward acceleration. Orbital mechanics or astrodynamics is the application of ballistics and celestial mechanics to the practical problems concerning the motion of rockets and other… …
7Black body — As the temperature decreases, the peak of the blackbody radiation curve moves to lower intensities and longer wavelengths. The blackbody radiation graph is also compared with the classical model of Rayleigh and Jeans …
8Computer facial animation — is primarily an area of computer graphics that encapsulates models and techniques for generating and animating images of the human head and face. Due to its subject and output type, it is also related to many other scientific and artistic fields… …
9Great Deluge algorithm — The Great Deluge algorithm (GD) is a generic algorithm applied to optimization problems. It is similar in many ways to the hill climbing and simulated annealing algorithms.The name comes from the analogy that in a great deluge a person climbing a …
