Since the original STARMAP packet switching or routing philosophy requires that a hub be responsible only for its own packets and that it needs no knowledge of events at any other hub then the routing table reorganization scheme must follow a similar philosophy. A primary hub routing table is changed in a very simple manner if it detects a failed transmission in one of its outlinks. The routing table is returned to its original condition as soon as the failed link or hub has been repaired.","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"159 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122697973","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 voltage signal is assumed to have a linear relation with the voltage magnitude and the phase angle. The coefficients of this linear relation are considered as fuzzy numbers with given middle and spread values. The spread defines the fuzziness of the function. The proposed technique uses digitized samples of the voltage signal obtained at the relay location. The problem is formulated as a linear optimization problem, where the objective is to minimize the spread of the fuzzy output for the whole data set, which is a linear function of the spread, subject to satisfying inequality constraints. A linear programming algorithm is used to solve the associated linear optimization problem. The proposed technique is tested using nonfuzzy as well as fuzzy data.","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122510808","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}

They are the simplest shape into which a 3D region can be broken, and are well-suited to automatic mesh generation. Hierarchical elements are finite elements which have the useful property that elements with different polynomial orders can be used together in the same mesh without causing discontinuities. This is highly desirable, because it permits polynomial order to be used to control the distribution of the degrees of freedom. This paper introduces a new hierarchical tetrahedral element in which the basis functions are constructed from orthogonal polynomials (Jacobi polynomials), allowing mixing of polynomial orders up to three. Explicit basis functions are given in addition to the description of the linear independence property. As was the case for regular elements the pre-calculation of universal matrices will yield faster and more accurate results. The derivation and the corresponding universal matrices for the new elements are also shown. The new elements are used to solve for the electrostatic potential in a 3D region (where there is no analytical solution).","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117037340","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}

Gabor (1946) presented a JFTA technique where a signal could be described as the sum of shifted and modulated Gaussian basis functions which are weighted by complex constants. Further developments have permitted the practical implementation of the Gabor transform on digital computers. However, these techniques were not well suited for real time processing of digital sequences of very long or of infinite length due to the requirement to receive and store the entire signal prior to processing. A solution to this is presented in the form of a window based Gabor transform (WBGT), which is suitable for filterbank implementations. It is developed based on the orthogonal like discrete Gabor transform (OLGT) and is implemented in filterbanks.","PeriodicalId":269440,"journal":{"name":"Proceedings of 1996 Canadian Conference on Electrical and Computer Engineering","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-05-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128743414","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}
