Puck criterion was used to determine the failure of composite materials, and the material properties were exponentially attenuated according to the failure mode. The secondary stress criterion and B-K criterion are used to determine the initial and final failure of the interface. Then, the compression failure process of composite stiffened plate was simulated, and the effectiveness of the model was verified by experiments. On this basis, the failure mechanism of debonding is analyzed. Debonding begins at the intersection of the flexural nodal line ( or anti-nodal line) and the free edge of the lower edge of the rib, and the inducing factor is torque (or transverse bending moment).","PeriodicalId":246841,"journal":{"name":"2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124945137","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}

Current pixel-wise classification methods often produce in complete and disconnected vascular map due to the lack of constraint on vessel connectivity and biased centerline localization. In this work, we formulate the centerline extraction as a centerline-based distance transformation(CDT) regression problem, which shows larger central response than conventional boundarybased distance transformation(DT). To enlarge connectivity constraint, vessel direction learning task is appended to provide connectivity contextual information. Moreover, we establish a Multi-task Attention Fusion Network to jointly learn the proposed CDT and vessel direction representation. Notably, the proposed Attention Fusion module concatenates multitask information across different paths and boosts network to converge efficiently. Finally, centerline points correspond to local maximum on learned CDT map at perpendicular vessel direction, which can be easily identified with Non-Maximum Suppression(NMS) algorithm. Experimental results show that our method yields a promising performance on vessel centerline extraction.","PeriodicalId":246841,"journal":{"name":"2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125330383","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}

To explore the propagation characteristics of multi-node human body communication, a non-uniform medium human body model is employed in this study to simulate the multi-node human communication channel at different distances based on finite difference time domain (FDTD) method. And the results demonstrate that the communication loss of multi-node human body will increase as the transmission distance goes longer. In-vivo experiments were carried out on the simulation models as well. The normalized received power was analyzed by using the maximum likelihood estimation (MLE) and the Akaike information criterion (AIC). Then it was further statistically analyzed by using different distribution models at 45MHz operating frequency, with multi-node communications measured within three meters. The maximum attenuation of the receiver power is only 6.7dB and the channel loss will increase with the node distance. By comparing the simulation and the measurement results, it is found that the two results have the consistent attenuation trend. By measurement, Frequency Shift Keying (FSK) data is transmitted at 3m and Bit Error Ratio (BER) ≤10^-5 for multi-node human body communication, which is thus verified to have certain reliability and stability as well as the feasibility.","PeriodicalId":246841,"journal":{"name":"2020 3rd International Conference on Advanced Electronic Materials, Computers and Software Engineering (AEMCSE)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131201066","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}
