For achieving higher performance of amorphous silicon thin film solar cell, the front-contact ZnO:Al is needed to be concerned. In this paper, we focus on how the front contact ZnO:Al influences the a-Si:H thin film solar cell. In order to understand the relationship between the front-contact ZnO:Al and device, we establish a model to simulate how the feature size of the textured ZnO:Al influence...
Electronic Commerce has offered a convenient way for people to go shopping on the Internet. However, it is difficult for Internet customers to select a valuable item from the great number of various products available on line. When we use a keyword and search in a EC website, the ranking algorithm of products is usually based on statistics or simply the shop manager's preference, which does not fully...
Most dynamic voltage and frequency scaling (DVS) techniques adjust only CPU parameters, however, recent embedded systems provide multiple adjustable clocks which can be independently tuned. When considering multiple components, energy optimal frequencies depend on task set characteristics such as the number of CPU and memory access cycles. In this work, we propose a realistic energy model considering...
Service discovery is a key concept in a distributed Grid environment. The first step towards Grid implement is the discovery of services. In this paper, we build a new Grid service matching graph based on the semantic similarity of function parameters and then an efficient search algorithm is presented to accomplish Grid service discovery. The experiment results show the algorithm proposed in this...
