71Lumped capacitance model — A lumped capacitance model, also called lumped system analysis,[1] reduces a thermal system to a number of discrete “lumps” and assumes that the temperature difference inside each lump is negligible. This approximation is useful to simplify… …
72Ultra fast laser spectroscopy — is the study of molecules on extremely short time scales (nanoseconds to femtoseconds) after their excitation with a pulsed laser. This method is used extensively to examine the energy states and electron dynamics of any molecule whose reaction… …
73Relaxation (NMR) — In nuclear magnetic resonance (NMR) spectroscopy and magnetic resonance imaging (MRI) the term relaxation describes several processes by which nuclear magnetization prepared in a non equilibrium state return to the equilibrium distribution. In… …
74Hydrostatic shock — The term hydrostatic shock describes the theory that a penetrating projectile produces remote wounding and incapacitating effects in living targets, in addition to local effects in tissue caused by direct impact, through a hydraulic effect in… …
75Hermite polynomials — In mathematics, the Hermite polynomials are a classical orthogonal polynomial sequence that arise in probability, such as the Edgeworth series; in combinatorics, as an example of an Appell sequence, obeying the umbral calculus; in numerical… …
76List of Ig Nobel Prize winners — This is a list of Ig Nobel Prize winners from 1991 to the present day. A parody of the Nobel Prizes, the Ig Nobel Prizes are given each year in early October around the time the recipients of the genuine Nobel Prizes are announced for ten… …
77Long-range dependency — A self similar phenomenon behaves the same when viewed at different degrees of magnification, or different scales on a dimension (space or time). Self similar processes can be described using heavy tailed distributions, also known as long tailed… …
78RL circuit — A resistor inductor circuit (RL circuit), or RL filter or RL network, is one of the simplest analogue infinite impulse response electronic filters. It consists of a resistor and an inductor, either in series or in parallel, driven by a voltage… …
79Large deviations theory — In Probability Theory, the Large Deviations Theory concerns the asymptotic behaviour of remote tails of sequences of probability distributions. Some basic ideas of the theory can be tracked back to Laplace and Cramér, although a clear unified… …
80Weissberger's model — Weissberger’s modified exponential decay model, or simply, Weissberger’s model, is a radio wave propagation model that estimates the path loss due to the presence of one or more trees in a point to point telecommunication link. This model belongs …
