A novel hybrid BiVO4–SiO2 composites with mesoporous composite structure were synthesized by hydrothermal calcination method. The as-prepared BiVO4/SiO2 hybrid material was characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, UV–vis diffuse reflectance spectroscopy and BET measurements, respectively. Its photocatalytic activity was evaluated by the performance...
Energy limitation has become a performance bottleneck for mobile ad hoc networks. IEEE 802.11 has been adopted as the current standard MAC protocol for ad hoc networks. However, it has not the ability of adjusting power level dynamically, that reduces the performance of network. A novel power controlled MAC protocol based on SNR in mobile ad hoc networks is presented in this paper. Simulation results...
State of charge (SOC) determination is an increasingly important issue in battery energy storage system. Precise knowledge of SOC allows the controller to confidently use the battery packpsilas full operating range without fear of over- or under-charging cells. Taking into account of some transformed parameters like voltage and current, this paper describes a novel adaptive online approach to determinate...
The genetic simulated annealing algorithm can get global solution with low computational load. By means of this algorithms optimization method, the support vector machines (SVM) radial basis probabilistic kernel parameters of the performance was found out. A special software was developed on this method, it can be used in different field and improved the application of SVM in industry area. Then,...
A home network could control many devices, all of them working together to keep your home comfortable, entertaining, and safe. Home network includes many appliances and heterogeneity networks, which need to different QoS , so how to realize the aim that guarantee the QoS is very important. This article focuses on QoS management in home network based on a hybrid network architecture. This network architecture...
