In this paper, a corrugated substrate integrated waveguide (CSIW) with no metallic vias is proposed, and its propagation characteristics are investigated via our numerical SOC de-embedding method. In our analysis, dominant operating modes in this CSIW at different frequencies are extensively discussed. In final, its complex propagation constant, i.e., phase and attenuation constants, is derived to...
Class discovery, which aims to identify the underlying category structure, is an important issue in pattern recognition and knowledge discovery. The key task in class discovery is to estimate the number of classes. Classical estimation approaches usually face the problems of low accuracy, high complexity, or difficulty in choosing an appropriate penalty function. In this paper, an effective class...
As the end point of the power system, a distribution system directly connects with the consumers. The reliability of power supply is directly related with consumers. However, uncertainty of the original parameters of components may be caused by lacking of statistical information and the statistic error. It will inevitably produce large errors if we directly use these parameters for evaluation. The...
In modern automotive industry supply chain, selecting suitable suppliers should have strategic view. However, it is multi-objective decisions which have many factors to be given consideration. Evaluation model is a way to realize scientific decision-making. In this paper, principal component analysis should be used to preprocess, and then make an analysis of the integrated evaluation method, TOPSIS...
Wireless mesh networks have promised to provide high-speed access for residential or mobile customers. And concurrent transmission is an effective way to enhance system throughput in wireless mesh networks. The objective of this paper is to provide an effective concurrent transmission method to enlarge throughput with specific QoS fairness guarantee in wireless mesh networks. Firstly, link relationship...
