Sun tracker is an automatic device that steers a PV array perpendicular to the solar irradiation, improving power output up to one-third. However, its feedback control is lack of accurate angle measurement that degrades the overall performance. A type of irradiation angle sensors is proposed in which the pyramid structure generate some currents containing the information of irradiation angle. To extract...
Complex networks of direct relevance to biomedicine have not yet been fully mapped largely due to the incompleteness, isolation, and heterogeneity of data. The Semantic Web, by providing a technical framework for the integration and sharing of heterogeneous databases in different domains, can potentially enable more effective complex network mapping and analysis. However, the feasibility of using...
Combine the actual situation of stope collapse area 56-7# of Dongguashan Copper Mine in china, three-dimensional dynamic monitoring the collapse area twice using Cavity Monitoring System (CMS), taking collapse area measured data as foundation, collapse area three-dimensional model created using Surpac and gain three-dimensional configuration and the actual boundary of the collapse area accurately...
An apparatus for detecting advanced glycation Endproducts (AGE) fluorescence spectrum of skin has been designed. Some of the AGE have special fluorescence. When the tissue of skin is illuminated with excitation light, fluorescence emmited by tissue is detected. The intensity of detected fluorescence is related with the concentration of tissue AGE, which can determine a tissue state of individual....
Reverse skyline queries have been proved very useful in business location, environmental monitoring and some other applications. In this paper, we consider reverse skyline queries processing on data stream, which provides continuous, high-speed data elements. Specifically, we consider the latest objects in the sliding window. The challenge is that it is difficult to maintain a multidimensional index...
