111ring — ring1 [riŋ] vi. rang or Now Chiefly Dial. rung, rung, ringing [ME ringen < OE hringan < IE echoic base * ker > RAVEN1, CREAK, L corvus, crow] 1. to give forth a clear, resonant sound when struck or otherwise caused to vibrate, as a bell …
112Bessel function — In mathematics, Bessel functions, first defined by the mathematician Daniel Bernoulli and generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel s differential equation: for an arbitrary real or complex number α (the order of the …
113Hypercomplex number — The term hypercomplex number has been used in mathematics for the elements of algebras that extend or go beyond complex number arithmetic.Hypercomplex numbers have had a long lineage of devotees including Hermann Hankel, Georg Frobenius, Eduard… …
114Avalanche photodiode — Avalanche photodiodes (APDs) are photodetectors that can be regarded as the semiconductor analog to photomultipliers. By applying a high reverse bias voltage (typically 100 200 V in silicon), APDs show an internal current gain effect (around 100) …
115Electron-multiplying CCD — An electron multiplying CCD (EMCCD, also known as an L3Vision CCD, L3CCD or Impactron CCD) is a charge coupled device in which a gain register is placed between the shift register and the output amplifier. The gain register is split up into a… …
116Nombre complexe — Pour les articles homonymes, voir complexe. En mathématiques, les nombres complexes forment une extension de l ensemble des nombres réels. Ils permettent notamment de définir des solutions à toutes les équations polynomiales à coefficients réels …
117Projet:Mathématiques/Liste des articles de mathématiques — Cette page n est plus mise à jour depuis l arrêt de DumZiBoT. Pour demander sa remise en service, faire une requête sur WP:RBOT Cette page recense les articles relatifs aux mathématiques, qui sont liés aux portails de mathématiques, géométrie ou… …
118Hall effect — For the Colombian band, see The Hall Effect (band). The Hall effect is the production of a voltage difference (the Hall voltage) across an electrical conductor, transverse to an electric current in the conductor and a magnetic field perpendicular …
119Plant hormone — Plant hormones (also known as phytohormones) are chemicals that regulate plant growth. Plant hormones are signal molecules produced within the plant, and occur in extremely low concentrations. Hormones regulate cellular processes in targeted… …
120Discrete time — This article is about discrete time in signal processing. For discrete time in quantum physics, see quantum time. Discrete time is the discontinuity of a function s time domain that results from sampling a variable at a finite interval. For… …
