The traditional sliding mode variable structure needs to combine the optimization algorithm to suppress the chattering problem. The sliding mode variable structure controller based on RBF neural network parameter adjustment can eliminate the chattering problem of sliding mode control to a certain extent, but the uncertainty of network self-learning effect will affect the convergence efficiency of parameters, in order to improve the approximation effect of the network. The RBF neural network and particle swarm optimization algorithm are combined organically, the particle swarm optimization algorithm is used to optimize the hidden layer basis function width of the RBF neural network and the self-learning, self-adaptive and self-organizing ability of the center improvement algorithm, and the PSO-RBF tuning law is designed to train and test the height step command and the speed step command. The efficiency of the parameter convergence of the sliding mode variable structure controller algorithm is improved. Through a large number of numerical simulations and controller algorithm comparison analysis, it is verified that the sliding mode variable structure controller of PSO-RBF tuning parameters has strong robustness in suppressing various uncertainties due to interference.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129402573","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}

Its main component is blade airfoil. The optimization of the airfoil can improve the efficiency of the turbine. According to the optimized method of cutting airfoil, the airfoil model was established by Gambit software and then imported into fluent software for the numerical simulation to get the velocity profile of the optimized airfoil. It can be seen that the turbine output power is the highest at d / c of 0.20. The optimized airfoil turbine lift resistance coefficient was calculated in CFD software. Finally, it was concluded that the lift-drag ratio and the energy efficiency of the optimized airfoil turbine were all larger than the basic airfoils. The average value was calculated and the energy-using efficiency was increased by about 30% the power generation efficiency of the sea current power generation device.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124626789","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}

First, it designed a special image acquisition device to solve the problem that the roller has the property of high light. Second, it proposed an improved grayscale compensation method to cope with uneven grayscale value of the image, which was extracted by coordinated information from the origin image. At last, the defect was segmented by using the histogram clustering method. Experiments show that the improved grayscale compensation method makes the image background more balanced and improves contrasts between the defect area and the background area. Compared with Niblack and background subtraction algorithm, the result shows that this method has a better performance on time cost and accuracy.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127623936","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}

In 2017, Huang et al. introduced the notion of inside keyword guessing attack (IKGA), which means the inside adversary could try out the keyword specified by a given trapdoor by guessing offline and proposed a scheme called Public-key Authenticated Encryption with Keyword Search (HQ-PAEKS) to solve this problem. However, the search complexity of HQ-PAEKS is linear to the total number of the encrypted indexes and may be not in a position to meet the demand of practical application. This paper combines the idea of Public-key Authenticated Encryption with hidden structure and proposes a practical scheme called Public-key Authenticated Encryption with Fast Keyword Search (PAEFKS), in which the search complexity for the cloud server presents linear relation with the number of the encrypted indexes matching the trapdoor sent from the data user. In addition, it gives security analysis to show that the scheme could protect index and keyword privacy well and experiments on real-world data sets show that the scheme indeed reduces the overhead on keyword search computation in the cloud.","PeriodicalId":332213,"journal":{"name":"2018 International Computers, Signals and Systems Conference (ICOMSSC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134405107","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}
