The components are the following: • Evaporator where the heat transferred from a process source or from a refrigerated space results in vaporization of the refrigerant (also called coolant) • Compressor where the gas refrigerant is compressed to a relatively high pressure and temperature. In addition, mechanical efficiency must be introduced (auxiliary power such as lubricant oil pump, etc.). Notice that in hermetic-compressors (in which the electric motor is placed in the same crank as the compressor)

Many multimedia applications can benefit from techniques for adapting existing classifiers to data with different distri- butions. One example is cross-domain video concept detec- tion which aims to adapt concept classifiers across various video domains. In this paper, we explore two key problems for classifier adaptation:
