Parallel solutions for two classes of linear programs are
presented. First we parallelized the two-phase revised simplex
algorithm and showed that it is possible to get linear improvement in
performance. The simplex algorithm is the best known algorithm for
solving linear programs, and we claim our result is the best...
Water-source and ice-maker heat pumps share many
characteristics. However, each presents different
technical difficulties that have prevented them from being
used more widely. In a water-source heat pump a very
important consideration is to reduce water consumption,
while in an ice-maker heat pump a major concern is to
reduce the...
A two year experiment demonstrated electrical energy savings
through evaporator fan cycling in part of a full-sized refrigerated
controlled atmosphere apple storage facility in Yakima, Washington.
Room cooling demand and evaporator fan operation was controlled by
the bulk fruit temperature. Refrigerant temperature was regulated
by a computer controlled ramping sequence...
