mergefrom Mass noun date October 2010 mergefrom Count noun date October 2010 mergefrom Telicity date October 2010 In linguistics , a quantized expression is such that, whenever it is true of some entity, it is not true of any proper subparts of that entity. Example If something is an apple , then no proper subpart of that thing is an apple . If something is water , then many of its subparts will also be water . Hence, apple is quantized, while water is not. Quantization has proven relevant to the proper characterization of grammatical telicity roughly, sentences that present events as bounded unbounded in time and the mass noun mass count distinction for nouns . The notion was first applied to linguistic semantics by the linguist Manfred Krifka . Formally, a quantization predicate QUA can be defined as follows, where math U math is the universe of discourse , and math F math is a variable over set mathematics sets , and math p math is a mereology mereological part mathematical structure structure on math U math with math p math the mereology mereological part of relation mathematics relation . center math forall F subseteq U p QUA F iff forall x,y F x wedge F y Rightarrow neg x p y math center See also Fewer vs. less References Krifka, Manfred 1989.

About quantization in music other uses Quantization disambiguation Unreferenced date December 2009 In digital music processing technology, quantization is the process of aligning a set of musical notes to a precise setting. This results in notes being set on beats and on exact fractions of beats. The most frequent application of quantization in this context lies within MIDI application software or hardware. MIDI sequencers typically include quantization in their manifest of edit commands. In this case, the dimensions of this timing grid are set beforehand. When one instructs the music application to quantize a certain group of MIDI notes in a song, the program moves each note to the closest point on the timing grid. The purpose of quantization in music processing is to provide a more beat accurate timing of sounds. Quantization is frequently applied to a record of MIDI notes created by the use of a musical keyboard or drum machine. Quantization in MIDI is usually applied to Note On messages and sometimes Note Off messages some digital audio workstation s shift the entire note by moving both messages together. Sometimes quantization is applied in terms of a percentage, to partially align the notes to a certain beat. Using a percentage of quantization allows for the subtle preservation of some natural human timing nuances. In recent years audio quantization has come into play, with the plug in Beat Detective on all version of Pro Tools being used regularly on modern day records to tighten the playing of drums, guitar, bass etc. The phrase pitch quantization can refer to pitch correction used in audio production, such as Auto Tune .

Unreferenced stub auto yes date December 2009 Orphan date December 2009 A first quantization of a physical system is a semi classical mechanics classical treatment of quantum mechanics , in which particles or physical objects are treated using quantum wave function s but the surrounding environment for example a potential well or a bulk electromagnetic field or gravitational field is treated classically. First quantization is appropriate for studying a single quantum mechanical system being controlled by a laboratory apparatus that is itself large enough that classical mechanics is applicable to most of the apparatus. First quantization is the subject studied in most undergraduate quantum mechanics courses, and in which the Schrodinger Equation and matrix mechanics Heisenberg matrix mechanics together with bra ket notation are most simply applied. It may be contrasted with Second quantization , which includes quantum mechanical uncertainty effects in all aspects of an experiment including the controlling fields and boundary conditions.

Trellis quantization is an algorithm that can improve data compression in Discrete cosine transform DCT based encoding methods. It is used to optimize residual DCT coefficients after Motion compensation Motion estimation motion estimation in lossy compression lossy video compression encoders such as Xvid and x264 . Trellis quantization reduces the size of some DCT coefficients while recovering others to take their place. This process can increase quality because coefficients chosen by Trellis have the lowest Rate distortion rate distortion ratio. Trellis quantization effectively finds the optimal quantization for each block to maximize the PSNR relative to bitrate . It has varying effectiveness depending on the input data and compression method.

Flux quantization is a quantum phenomenon in which the magnetic field is quantized in the unit of math h 2e math , also known variously as flux quanta, fluxoids, vortices or fluxon s. Flux quantization occurs in Type II superconductor s subjected to a magnetic field. Below a critical field H sub c1 sub , all magnetic flux is expulsed according to the Meissner effect and perfect diamagnetism is observed, exactly as in a Type I superconductor . Up to a second critical field value, H sub c2 sub , flux penetrates in discrete units while the bulk of the material remains superconducting. Both critical fields are temperature dependent, and tabulated values are the zero temperature extrapolation unless otherwise noted.

In quantum mechanics , spatial quantization is the quantization of angular momentum in Three dimensional space three dimensional space. It results from the fact that the angular momentum of a rigid rotor is expressed in three dimensions, and is quantized. For a rigid rotor, it is possible to know L sup 2 sup the square of the magnitude of angular momentum and L sub z sub the z component of angular momentum simultaneously because these two quantum mechanical Operator physics operators commutation mathematics commute . However, it is not possible to know L sub x sub and L sub y sub , which are the other two components of angular momentum, simultaneously and exactly. With the magnitude and z component of angular momentum exactly known, the angular momentum vector points from a single point at a certain angle, but it can end anywhere on a circle. The result is a cone geometry cone whose vertex is the origin of the vector, and whose height is the z component. Since the x and y components are not known, the angular momentum can be represented by any of the vectors that comprise the cone. Spatial quantization results from the fact that only a small number of values for L are allowed in quantum mechanical systems. For example, if the rules of the system require that L be an integer in the set 2, 1, 0, 1, 2 , then there are only five surfaces on which the angular momentum can be found a flat circle corresponding to L 0, and two cones above this circle for L 1 and L 2, and two cones below this circle for L 1 and L 2. In classical mechanics , spatial quantization does not occur because a large number of values are allowed for L. As the number of allowed values for L approaches infinity, the number of imaginary cones approaches infinity, and the circles form an essentially continuous sphere, so that the momentum vector can be anywhere on the sphere. In quantum mechanics, the angular momentum can only lie on a small number of circles on the imaginary sphere. References Thomas Engel ... more details

Landau quantization in quantum mechanics is the quantization of the cyclotron orbits of charged particles in magnetic fields. As a result, the charged particles can only occupy orbits with discrete energy values, called Landau levels. The Landau levels are degenerate, with the number of electrons per level directly proportional to the strength of the applied magnetic field. Landau quantization is directly responsible for oscillations in electronic properties of materials as a function of the applied magnetic field. It is named after the Soviet physicist Lev Landau .
