Designing complex tile shape is difficult for ordinary people due to mathematical constraints and artistry requirements. The proposed method automatically generates shapes which reflect adjectives the user wants to express using GAN, and the shapes are refined by human interaction with IEC, so that the obtained shape becomes fully satisfactory to the user. Here, datasets of shapes are prepared for several adjectives first, and GAN is trained using random latent vectors to generate shapes for each adjective. The values in the latent vector are controlled by IEC to consider the user’s preference. The proposed method is shown to be effective in computer simulation and its subjective test.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"142 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":"116342242","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 rapid development of VLSI technology has created new difficulties for design and test engineers. The power consumption of the test is one of the important issues. This article describes a scanning architecture that enables high-quality and low-power testing by modifying test samples in test applications. When the test sample switches a large number of scan flip-flops in each shift, the stability of the circuit is lowered, the fault verification is difficult, the product yield is reduced, and the life is shortened, which is a serious problem. In the paper structure, part of the displacement power is solved. One method is to reduce the number of toggle triggers and reduce the switching activity caused by the move of test samples. The method calculates the switching activity of the scan trigger during the scan operation. Move to the appropriate scan path in the test sample.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"7 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":"126317709","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, the characteristic polynomial of graph Laplacian matrix is used to show that the upper bound of filter length is the number of vertex of graph.

Next, the numerical examples of cycle graph and path graph are illustrated to show the effectiveness of the proposed reduction methods.

The designed QVCO is based on a parallel-coupled QVCO with an integrated LC tank. The QVCO is implemented using the TSMC 0.18 μm CMOS standard process. Measurements of the injection-locked QVCO are made, revealing that the phase error are reduced from 2.44° to 0.32°. The reductions of the phase error is 2.12°.

Currently, one of the most widely used technologies for estimating the position of a vehicle is a method using a Global Navigation Satellite System (GNSS). GNSS is one of the technologies to determine the outdoor position and uses the signals provided by artificial satellites to determine one’s position. However, due to different causes of error, general GNSS cannot estimate the precise position. To solve this problem, a Real-Time Kinematic (RTK) technology which can improve precision by using correction data provided by a base station has been developed. RTK can estimate a more precise position than GNSS. However, if the integer ambiguity cannot be precisely calculated, a precise position of the centimeter (cm) level cannot be estimated. In this paper, we propose a method for estimating a more precise position using the Kalman filter to improve the precision of the position estimated using RTK, and show the results of experiments.","PeriodicalId":359822,"journal":{"name":"2021 International Symposium on Intelligent Signal Processing and Communication Systems (ISPACS)","volume":"116 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":"132510293","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}
