Particle decay — is the spontaneous process of one elementary particle transforming into other elementary particles. During this process, an elementary particle becomes a different particle with less mass and an intermediate particle such as W boson in muon decay … Wikipedia
Particle filter — Particle filters, also known as sequential Monte Carlo methods (SMC), are sophisticated model estimation techniques based on simulation. They are usually used to estimate Bayesian models and are the sequential ( on line ) analogue of Markov chain … Wikipedia
Particle radiation — is the radiation of energy by means of fast moving subatomic particles. Particle radiation is referred to as a particle beam if the particles are all moving in the same direction, similar to a light beam.Due to the wave particle duality, all… … 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
Initial-stress-derived noun — Initial stress derivation is a phonological process in English, wherein stress is moved to the first syllable of any of several dozen verbs when they become nouns or adjectives. This is called a suprafix in linguistics. It is gradually becoming… … Wikipedia
