During winter operation, an air-source heat pump extracts heat from the cold outside air and releases the heat into the living space. At certain outside air conditions, when it operates in heating mode, frost can form on the air-cooled heat exchanger, decreasing the heating performance....

A HfB2-SiC ceramics were fabricated via a reactive hot pressing using Hf, B4C, and Si as precursors. The reaction temperature for the reactive hot pressing between 1800 and 1900°C was determined by reaction of the precursor at different temperatures from 900 to 1800°C. The effective size...

Service-processes of electronic retailers are founded on electronic technologies that provide flexibility to sense and respond online to the dynamic and complex needs of customers. In this paper, we develop a taxonomy of service-processes in electronic retailing and demonstrate their linkage to...
