Abstract: Solar energy can be converted effectively into electrical or mechanical energy. The radiant heat of the sun is collected by a parabolic dish, concentrated intensely, and reflected into a cavity ...

Abstract: The absorption of solar heat and the attendant thermal and mechanical loadings on the tubes of cavity receivers depend predominantly on the flux distribution of the incident solar radiation. ...

Abstract: This paper describes the analysis, design, implementation, and evaluation of an electronically controlled fluid back-pressure regulator system. The control scheme is unique in that it is purely ...

Abstract: Because of the limitations posed by the topographic conditions, buildings located on hill slopes have highly irregular configurations in comparison with buildings located on flat terrain. Extensive field surveys were ...

Abstract: A new test procedure is proposed for the field acceptance testing of large hydroelectric turbines. This procedure is an improvement over existing procedures in that it generates test data from ...

Abstract: A new device designed to harvest rotational vibration energy is presented. The device is modeled as a spring-mass-damper system connected to a vibration source where a torsion rod is used as ...
