• Speed of sound — Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a certain amount of time. In SI Units with dry air at 20 °C (68 °F), the speed of sound is 343 m/s. This… …   Wikipedia

• Compression ratio — For compression ratio in data compression, see data compression ratio. The compression ratio of an internal combustion engine or external combustion engine is a value that represents the ratio of the volume of its combustion chamber from its… …   Wikipedia

• Compression driver — A compression driver is a type of loudspeaker driver which uses the technique of compression to achieve high efficiencies. In this context compression refers to the fact that the area of the loudspeaker diaphragm is significantly larger than the… …   Wikipedia

• Compression lift — The XB 70 had folding wingtips to enhance both compression lift and directional stability at high speeds. In aerodynamics, compression lift refers to an aircraft that uses shock waves generated by its own supersonic flight to generate lift …   Wikipedia

• Compression release — A compression release mechanism works to ease the starting of internal combustion engines by allowing them to spin up to starting speed without having to work against the pumping action of the pistons. It does this through a release valve that is …   Wikipedia

• compression lift — An additional lift gained at supersonic speeds by forcing airflow to accelerate beneath the wing. Under surface of wing acts as a diverging duct. Both pressure (P) and velocity (V) increase at supersonic speed but the increase in velocity is… …   Aviation dictionary

• Lossless data compression — is a class of data compression algorithms that allows the exact original data to be reconstructed from the compressed data. The term lossless is in contrast to lossy data compression, which only allows an approximation of the original data to be… …   Wikipedia

• Data compression — Source coding redirects here. For the term in computer programming, see Source code. In computer science and information theory, data compression, source coding or bit rate reduction is the process of encoding information using fewer bits than… …   Wikipedia

• Audio compression (data) — For processes which reduce the amount of time it takes to listen to and understand a recording, see time compressed speech. Audio compression is a form of data compression designed to reduce the size of audio files. Audio compression algorithms… …   Wikipedia

• Lossy compression — A lossy compression method is one where compressing data and then decompressing it retrieves data that may well be different from the original, but is close enough to be useful in some way. Lossy compression is most commonly used to compress… …   Wikipedia
