Professional DiscVideo tape tracking: In a video tape recorder, tracking is a calibration adjustment which ensures that the spinning playback head is properly aligned with the helical scan signal written onto the tape.Cascade storage system: A cascade storage system is a high pressure gas cylinder system which is used for the refilling of smaller compressed gas cylinders or air cylinders. Each of the large cylinders is filled by a compressor, but the cascade system allows small cylinders to be filled without a compressor.University College of Applied Sciences: University College of Applied Sciences (UCAS) is a technical college in Gaza founded in 1998. It offers 40 majors in engineering, health, technology, administration, education and the humanities.Mechanochemistry: Mechanochemistry or mechanical chemistry is the coupling of mechanical and chemical phenomena on a molecular scale and includes mechanical breakage, chemical behaviour of mechanically stressed solids (e.g.Jeff Wayne's The War of the Worlds (1998 video game): Jeff Wayne's The War of the Worlds is a real-time strategy video game developed by Rage Software Limited and released for Windows-based PCs in 1998. It is based on Jeff Wayne's Musical Version of The War of the Worlds — which is itself based on H.Voluntary Parenthood League: The Voluntary Parenthood League (VPL) was an organization that advocated for contraception during the birth control movement in the United States.

This interaction represents a combination of predation and competition, because both species rely on the same prey resources and also benefit from preying upon one another.Riding-like sittingWalker (BEAM): In BEAM robotics, a walker is a walking machine that has a driven mode of locomotion by intermittent ground-contacting legs. They usually possess 1 to 12 (generally, three or less) motors.Beta encoder: A beta encoder is an analog to digital conversion (A/D) system in which a real number in the unit interval is represented by a finite representation of a sequence in base beta, with beta being a real number between 1 and 2. Beta encoders are an alternative to traditional approaches to pulse code modulation.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingNon-rapid eye movement sleepMatrix model: == Mathematics and physics ==Ventricular action potential
