Focusing on the effective use of low-grade solar heat as heat source to provide refrigeration for residential and commercial space cooling, an absorption-compression hybrid refrigeration cycle has been studied on the basis of available data of working pair 1,1,1,2-tetrafluoroethane (R134a) and...

This paper applies n-person cooperative game theory to analyze the efficient cost allocation problem of a three communities contructing a common sewage system.

After tremendous growth of wind power generation capacity in recent years, China now has 44.7 GW of wind-derived power. Despite the recent growth rates and promises of a bright future, two important issues - the capability of the grid infrastructure and the availability of backup systems - must...

Understanding of current distributions in proton exchange membrane fuel cells (PEMFCs) is crucial for designing cell components such as the flow field plates and the membrane electrode assembly (MEA). In this study, the spatial current density distributions in a single PEMFC with three...

This paper examines the major driving forces behind the conversion of arable land to non-agricultural uses in china during the reform years (1978-1995). Both graphic techniques, based on a Geographic Information System (GIS), and an econometric modeling approach are employed. It is found that...

Malaria is an infectious disease that is caused by a group of parasites of the genus "Plasmodium". Characterizing the association between polymorphisms in the parasite genome and measured traits in an infected human host may provide insight into disease aetiology and ultimately inform new...
