We model a solar-assisted heat pump (SAHP) system in order to develop a design criterion. A steady-state model is chosen, which lends itself to optimal analytic solutions. From a physical understanding of these solutions, a design criterion is developed. This criterion reveals that, for optimum...

The growing public interest in and global consciousness of environmental and social issues have intensified pressures on forest industry companies in their efforts to effectively balance potentially conflicting stakeholder demands. In this paper, we conceptually analyze corporate responsibility...

The electricity generation technologies and systems are complex and change in very dynamic fashions, with a multitude of energy sources and prime movers. Since an important concept in generator design is the "economies of scale", we discover that the installed maximal unit size (capacity) of the...
