Research on transmission performance of a surface acoustic wave sensing system used in manufacturing environment monitoring

Surface acoustic wave (SAW) sensors show great promise in monitoring fast-rotating or moving machinery in manufacturing environments, and have several advantages in the measurement of temperature, torque, pressure, and strain because of their passive and wireless capability. However, very few studies have systematically attempted to evaluate the characteristics of SAW sensors in a metal environment and rotating structures, both of which are common in machine tools. Simulation of the influence of the metal using CST software and a series of experiments with an SAW temperature sensor in real environments were designed to investigate the factors that affect transmission performance, including antenna angles, orientations, rotation speeds, and a metallic plate, along with the interrogator antenna–SAW sensor antenna separation distance. Our experimental measurements show that the sensor’s optimal placement in manufacturing environments should take into account all these factors in order to maintain system measurement and data transmission capability. As the first attempt to systematically investigate the transmission characteristics of the SAW sensor used in manufacturing environment, this study aims to guide users of SAW sensor applications and encourage more research in the field of wireless passive SAW sensors in monitoring applications.

Clustering-based selective neural network ensemble

INTRODUCTION Neural network ensemble is becoming a hot spot in machine learning and data mining recently. Many researchers have shown that simply combining the output of many neural networks can generate more accurate predictions than that of any of the individual networks. Most previous work either focused on how to combine the output of multiple trained networks or how to directly design a good set of neural networks. Theoretical and empirical work showed that a good ensemble is one wh…

公共治理视阈下的公民参与

建基于公共治理的理论内涵,着重从公共治理及公民个体层面分析了公共治理的价值诉求——公民参与,即从公共治理层面而言,公民参与是公共治理主体多元化的客观要求,有助于增强政府的合法性,有助于公共治理目标的实现;从公民个体层面而言,公民参与是实现公民权的基本保障,有助于提升公民的“主人翁”意识,有助于公民自身利益的实现。进而提出促进公民有效参与公共治理的路径选择：培育成熟的公民社会,提升公民的政治素质,构建公共责任体系。
