Particle system — The term particle system refers to a computer graphics technique to simulate certain fuzzy phenomena, which are otherwise very hard to reproduce with conventional rendering techniques. Examples of such phenomena which are commonly replicated… … Wikipedia
Particle in a spherically symmetric potential — In quantum mechanics, the particle in a spherically symmetric potential describes the dynamics of a particle in a potential which has spherical symmetry. The Hamiltonian for such a system has the form:hat{H} = frac{hat{p}^2}{2m 0} + V(r)where m 0 … Wikipedia
Particle — may refer to:In chemistry: * Colloidal particle, part of a one phase system of two or more componentsIn physics: * Subatomic particle, which may be either: **Elementary particle, a particle of which larger particles are composed, also called a… … Wikipedia
Particle image velocimetry — (PIV) is an optical method used to measure velocities and related properties in fluids. The fluid is seeded with particles which, for the purposes of PIV, are generally assumed to faithfully follow the flow dynamics. It is the motion of these… … Wikipedia
Particle tracking velocimetry — (PTV) is one of velocimetry methods, i.e a technique to measure velocity of particles. The name suggests that the particles are tracked, and not only recorded as an image as it is suggested in another form, particle image velocimetry. There are… … Wikipedia
Particle swarm optimization — (PSO) is a swarm intelligence based algorithm to find a solution to an optimization problem in a search space, or model and predict social behavior in the presence of objectives.OverviewParticle swarm optimization is a stochastic, population… … Wikipedia
Particle Mesh — (PM) is a computational method for determining the gravity forces in a system of particles. These particles could refer to atoms, stars, or fluid components and so the method is applicable to many fields, including molecular dynamics and… … Wikipedia
Particle therapy — Intervention ICD 9: 92.26 Particle therapy is a form of external beam radiotherapy using beams of energetic protons, neutrons, or positive ions for cancer treatment. The most common … Wikipedia

Two-body problem — Two bodies with similar mass orbiting around a common barycenter with elliptic orbits. In classical mechanics, the two body problem is to determine the motion of two point particles that interact only with each other. Common examples include a… … Wikipedia
Two-photon absorption — (TPA) is the simultaneous absorption of two photons of identical or different frequencies in order to excite a molecule from one state (usually the ground state) to a higher energy electronic state. The energy difference between the involved… … Wikipedia
