The performance of superdirective beamforming of a practical circular hydrophone array is investigated. The received signal of a 16-element circular hydrophone array with radius of 0.25m are measured in the anechoic water tank. The array manifold at the frequency of 1.11kHz is obtained. The superdirective beamforming of the circular array is designed and realized. The correctness and effectiveness...
Imperfection of remote sensing data greatly affects the performance of information fusion algorithm. To solve this problem, a Gaussian kernel-based Fuzzy Rough Set fusion algorithm is proposed, since Fuzzy Rough Set theory is an effect tool to model uncertainties of data. For feature reduction a novel index is proposed to evaluate the significance of features, considering both the relevance between...
A comprehensive investigation of silicon microring sensor, which is used for temperature detection, is reported in this paper, and the theory was introduced in detail. Numerical analysis shows that the silicon microring has a high sensitivity and a very good linearity between real-time temperature and effective index. By optimizing the parameters, the microring sensor can obtain a higher sensitivity...
Evaluation method of service quality of restaurant is studied in this paper. Based on SERVQUAL, Evaluation system for restaurant is established. And empirical study is done for a restaurant in Mianyang,china. Service quality of the restaurant is evaluated by the restaurant's service quality evaluation method based on SERVQUAL. Then according to current service quality level of the restaurant, quality...
In supply chain operations, there may be many disruptions, which cause much costs and reduce supply chain performance. So, it is necessary for corporations to understand the anti-disruption capability of the supply chain which they participate in. This paper designs a new evaluation system which is more appropriate to test the supply chain anti-disruption capability. And according to the proposed...
