With more and more customers participate in online shopping, and the online shopping service providers need to improve the quality of service to attract customers to improve customer satisfaction. Based on SERVQUAL model, this paper explores the association between various dimensions of service quality of the web-based shopping and customer satisfaction and service loyalty, and gives an analysis of the five dimensions of quality of service in the context of online shopping, the relationship between service quality and customer satisfaction and loyalty, and thus providing the reference for online shopping service.展开更多

The AUV is embedded with multiple sensors, which are only able to detect the signal strengths of the source with unknown distribution. To resolve this challenge,a sensor configuration is explicitly designed as a semicircle to estimate gradients of the signal field.Then, a controller is obtained via the estimated gradients to drive the AUV to approach the source.Moreover, an upper bound for the localization error is provided in terms of the radius of the semicircle and the signal distribution. Finally, the authors include a simulation example by applying the strategy to a Remote Environmental Monitoring Unit S（REMUS） for seeking the deepest point of a region of seabed in the South China Sea.展开更多
