Firstly, the simulation model was established while the same inter-turn fault was set in nine different positions uniformly. Secondly, the influence of the fault on the magnetic field of DAR were obtained by comparing the spatial magnetic field distribution along the Axial Traverse in Center(ATC) and Lateral Traverse in Center(LTC). The comparison and in-depth study of the spatial magnetic field distribution of DAR between inter-turn short-circuit faults occurs in different positions provides a reliable theoretical basis for the feasible fault detection method.","PeriodicalId":140420,"journal":{"name":"2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132817033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, node-based label propagation algorithms are widely used in overlapping community detection research because of its simple and rapid advantages. However, these kinds of algorithms are always random, and sometimes even divide all nodes into one community. In this paper, to detect overlapping communities in complex networks and improve the robustness of label propagation algorithms, edges are chosen for detection instead of nodes, because overlapping community structures can be naturally obtained by edge-based detection algorithms. We propose a seed-edge-based link clustering label propagation algorithm (SELPA). Meanwhile, to improve the accuracy of the algorithm, the SELPA algorithm merges and optimizes the overlapping communities from the perspective of improving the modularity. Experiments on several real-world networks demonstrate that the proposed method is more robust and accurate than the existing algorithms based on label propagation in overlapping community detection.","PeriodicalId":140420,"journal":{"name":"2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124319260","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the complexity of the physical structure of the upper limb of the human body, the joints of the robot are difficult to be aligned with the human joints in real time.

Nowadays, more and more rehabilitation robots aim at clinical requirements such as being lightweight and the friendly interaction between robot and patient. So in this paper, we present the design and analysis of a compliant elbow-joint for arm rehabilitation robot which focuses on human-robot interaction. Firstly, a cable-driven arm rehabilitation robot is designed for the shoulder and elbow rehabilitation, which has the property of lightweight and flexibility. Secondly, an axis-adjustable elbow joint is designed to achieve real-time alignment with the skeletal elbow joint using a set of compliant mechanisms.

In the application of the ORPD, the fitness function is the total real loss of the distribution network. Inequality constrains are handled by the limitation of searching space. The simulation results on the IEEE-14 bus standard system and a real distribution network illustrate the feasibility and effectiveness of the algorithm. The total real power losses decrease 7.1% and 8% in two applications.

As the basis of system, SAR image registration has a direct impact on guidance precision. However, due to some inherent characteristics, especially the polarization and speckle noise, we need to adopt more effective approach to achieve the high precision and low computation of SAR guidance system than other optical image based systems. Therefore, in this paper, first, we implement NLM (Non-local Means) filter to improve the image quality damaged by speckle. Then, at feature detection and description stage, we adopt well-known FAST (Features from Accelerated Segment Test) and gradient-based binary descriptors, LDB (Local Difference Binary), to overcome strict real-time requirement and polarization phenomenon. Finally, at matching stage, in order to increase the number of correct pairs, the FSC (Fast Sample Consensus) is used to discard outliers matched by Hamming distance. And the transformation parameters could be estimated with affine model. To evaluate the performance of algorithms, three comparative experiments have been accomplished. The results demonstrate a good performance of our proposed method.","PeriodicalId":140420,"journal":{"name":"2018 13th IEEE Conference on Industrial Electronics and Applications (ICIEA)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116919705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
