Time base correction (TBC) is a technique to reduce or eliminate errors caused by mechanical instability present in analog recordings on mechanical media. Without time base correction, a signal from a videotape recorder (VTR) or videocassette recorder (VCR), cannot be mixed with other, more time-stable devices found in television studios and ...
Electricity price area. An electricity price area is a zone throughout which the electricity is traded at the same spot price on a power exchange. An electricity price area is decided by transmission system operator and can be a whole country, or parts of it. [1]
To help with firing, newer ABL systems utilize tracking lasers which have been tested recently in 2007 when the US Missile Defense Agency tested the track illuminator laser (TILL). The TILL is a solid state laser and is a key part of the fire control of the ABL system. Issues. Operational costs of an airborne laser are quite high.
Deep Space Optical Communications Demonstration. Deep Space Optical Communications ( DSOC) is a laser space communication system in operation that improved communications performance 10 to 100 times over radio frequency technology without incurring increases in mass, volume or power. [1] DSOC is capable of providing high bandwidth downlinks ...
The Philadelphia Industrial Correction Center (PICC) opened in 1986 holds approximately 900 medium custody adult male inmates. It was the first PDP facility constructed to operate on the basis of unit management. PICC's is split into 13 housing units arranged around separate yards, laundry facilities, medical triage areas, counseling rooms, and ...
v. t. e. In economics, a price system is a system through which the valuations of any forms of property (tangible or intangible) are determined. All societies use price systems in the allocation and exchange of resources as a consequence of scarcity. [1] Even in a barter system with no money, price systems are still utilized in the ...
