This paper deals with a multi-objective optimization of a novel micro solar driven combined power and ejector refrigeration system (CPER). The system combines an organic Rankine cycle (ORC) with an ejector refrigeration cycle to generate electricity and cold capacity simultaneously. Major thermodynamic parameters, namely turbine inlet temperature, turbine inlet pressure, turbine back pressure, ...

Mathematical model describing energetic efficiency (defined as a ratio of energy obtained in the form of biofuel to the sum of energy inputs necessary to facilitate production) of agricultural subsystem as a function of technological parameters was developed. Production technology is characterized by parameters of machinery, topological characteristics of the plantation as well as transportatio...

Three distinct and interacting types of entities: people, software agents and e-markets are considered in this paper. These entities operate within Shaman, a proposed framework for the construction and operation of heterogeneous systems enabling business interactions such as auctions and negotiations between software and human agents across those systems. Shaman is a dss-centric software enviro...

n what follows, we describe the technique and history of energetic neutral atom (enA) imaging of space plasma and present recent results from international collaborations involving enA imaging experiments as well as results from the imAge mission at earth and the cassini mission at Jupiter and saturn. both imAge and cassini carry ApL-built enA cameras. The henA instrument onboard the imAge miss...

Revitalizing our understanding of species distributions and assembly in community ecology requires greater use functional (physiological) approaches based on quantifiable factors such as energetics. Here, we explore niche partitioning between bumble honey bees by comparing a measure within-patch foraging efficiency, the ratio flower visitation rate (proportional to energy gain) body mass (energ...
