variable compression
11Compression de flux magnétique — Générateur magnéto cumulatif Les générateurs magnéto cumulatifs sont des générateurs de hautes puissances pulsées fonctionnant par compression d un flux magnétique à l aide d explosifs. La compression de flux électromagnétique sans explosif est… …
12Variable star — A star is classified as variable if its apparent brightness as seen from Earth changes over time, whether the changes are due to variations in the star s actual luminosity, or to variations in the amount of the star s light that is blocked from… …
13Variable-width encoding — This article is about the storage of text in computers. For the transmission of data across noisy channels, see variable length code. A variable width encoding is a type of character encoding scheme in which codes of differing lengths are used to …
14Variable-gain amplifier — A variable gain or voltage controlled amplifier is an electronic amplifier that varies its gain depending on a control voltage (often abbreviated CV). VCAs have many applications, including audio level compression, synthesizers and amplitude… …
15Variable force solenoid — A variable force solenoid (VFS) is an electro hydraulic device that controls pressure proportionally or inversely proportionally to a signal (voltage or current) obtained from the on board controller of a powertrain. A low flow VFS is used as a… …
16Variable Bit Rate — WikiV A compression scheme in which each unit of input material can be compressed to different sizes. For MPEG 2 video, for example, this means that “easier” sequences (that is, with no motion) can compress to very small sizes, whereas “hard”… …
17variable rate springs — springs which become stiffer under compression; variable rate gas springs are a feature of air suspension systems …
18variable decelerations — in fetal heart rate monitoring, a transient series of decelerations in heart rate that vary in duration, intensity, and relation to uterine contractions; they are abrupt in onset and cessation and result from vagus nerve firing in response to… …
19Homogeneous charge compression ignition — Thermodynamics …
20Homogeneous Charge Compression Ignition — Homogeneous Charge Compression Ignition, or HCCI, is a form of internal combustion in which well mixed fuel and oxidizer (typically air) are compressed to the point of auto ignition. As in other forms of combustion, this exothermic reaction… …
