The research method is used the fault tree analysis (FTA) to analyze the signal problems through expert experiences into a tree diagram and to find out the cause of fault. Then, set the tag to different characteristics, the Kernel Principal Component Analysis (KPCA) is used to reduce the dimensionality and feature extraction of the data, it reduces the computational time and defines the relevance of the fault cause with the alarm sensor. For classification and fault diagnosis technology, the Support Vector Machine (SVM) with optimized characteristics is used to train the model. The experimental results show that the proposed techniques would be improved the accuracy and it will help the marine officers to shorten the debugging time and problem diagnosis time.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121206669","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}

The multi-scale retinex (MSR) is an excellent contrast enhancement method for such images. However, MSR contains many parameters to be determined and it is not easy to determine those parameters properly. In the proposed method, the dynamic range of the entire image is maintained by adding the single scale retinex (SSR) result to the scaled original image, and the contrast is effectively improved. The proposed method has few parameters to be determined. Therefore, it is clarified that the parameters can be determined by specifying the difference between the average values of the whole image before and after enhancement.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123745827","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}

The results confirmed that the position estimation accuracy was improved by applying machine learning using a neural network model of TensorFlow. The neural network enables highly accurate position estimation in consideration of the complex indoor radio wave environment by learning the mapping from the RSS data space to the physical space.

We have already evaluated the performance using F0 estimation for noise corrupted speech with additive white Gauss noise or Pink noise. The IRAPT algorithm implemented the F0 estimation for the estimated complex AR residual from an analytic signal. We have found that a bone-conducted (BC) pre-filter makes it possible to improve the performance since the BC filter can suppress the additional noise. The BC characteristics are that of a low pass filter; as a result, a first-order AR filter can simulate the BC filter. This paper introduces first-order and second-order AR filters as the pre-filter to improve the F0 estimation performance.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128982156","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}

The property of blind signature makes sure that the signer does not know the message of the signature by the receiver chosen, on the other hand, the property of the zero-knowledge set membership makes sure that the message of the signature by the receiver chosen is one of the set original messages.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"1 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114099273","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}
