The proposed integrated-magnetic form of the network uses only three passive circuit components and two diodes and does not require any active switch elements. The preconverter also naturally translates the normally pulsating current drawn by a user power converter into a nonpulsating form, whose AC ripple current magnitude can be reduced to near-zero value by magnetics design.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124387016","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 algorithm assumes a dense set of world points obtained from passive stereovision, and reconstructs a 3D scene. The stratification of random points follows a few heuristic rules. Triangles are formed only between strata, greatly limiting the search. The separation of surfaces is implemented by the standard region growing technique, from which road segments, obstacles, and other perceptual information can be derived. Some synthetic tests are shown to verify the algorithms. The envisaged application is autonomous navigation, e.g. of mobile robots.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"4 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125673183","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}

A technique for reducing device voltage stresses that consists of using a nonlinear resonant capacitor is introduced. To allow the inverter to be regulated by the conventional PWM strategies, a technique is proposed which consists of interrupting the resonant cycle by an auxiliary switch. The principle of operation and a theoretical analysis of one of the topologies are presented. A laboratory prototype of a single-phase inverter regulated by PWM with harmonic elimination has been built and tested. The results of the experimental studies are reported.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"272 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115903600","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 input-output relationship of the proposed model is obtained, and its periodically time varying property is discussed. An application of the proposed model to spectrum scrambling is considered. A structure suitable for realizing the spectrum scrambling within the scope of real computations is presented, and its design procedures based on the bifrequency map are described. It is demonstrated that the proposed structure can be used to implement a spectrum scrambler, whether FIR or IIR (finite or infinite impulse response) filters are used. A design example is given to verify the effectiveness of the proposed design procedures for the realization of a spectrum scrambling system when both FIR and IIR time-invariant filters can be used.<<ETX>>","PeriodicalId":253424,"journal":{"name":"[Proceedings] IECON '90: 16th Annual Conference of IEEE Industrial Electronics Society","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1990-11-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132218533","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 approach, called sequence recognition, is based on the idea that time is a major item of information in the diagnosis. The aim is to use an expert system to achieve online diagnosis. Instead of considering time management as a problem, it is used to discriminate the symptoms at the entry of the diagnostic module. The approach allows simultaneous errors to be diagnosed.
