The architecture of the agent is implemented making use of a fuzzy associative memory (FAM) and feedback control laws. The FAM is used to address the action selection problem known for this architecture. The FAM defines different fuzzy conditions. These conditions are associated to feedback control laws. The integrated control signal is obtained by defuzzifying the FAM through the weighted average technique. The time-response of the agent is simulated on a model of the Ball and Beam system and validated with an implementation at the laboratory. The results show the behavior of the variables of the system and the dynamic characteristics of the agent. The control signals stay active at every moment and the FAM allows smooth transitions between them, depending on the fuzzy condition of the system.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131064656","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}

Typical applications are vibration measurements and active noise control related to rotating machinery and calibration equipment that can avoid the changes of the line frequency by adaptation. Higher frequency applications have limitations since the computational complexity of these analyzers are relatively high as the number of harmonic components to be measured (or suppressed) is usually above SO. Recently, a fast-filter bank structure has been proposed for adaptive Fourier analysis based on the combination of the concept of transform domain signal processing and the adaptation of a simple linear combiner. It results in the reduction of the above computational complexity, however for the correct use we have to have pre-estimation about the range of the fundamental frequency (or frequencies) to be able to set the applied single-input multiple-output filter-banks, which in many cases causes significant and possibly non-tolerable delay in the operation. In this paper a new fuzzy logic supported frequency range estimation procedure is proposed which makes possible to execute the frequency estimation in the first half of the period of the unknown signal, i.e. the adaptation and Fourier Analysis can be performed without any delay.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"325 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123307617","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, a trigonometric regression algorithm will find the approximating Fourier coefficients. Finally a multiple regression algorithm to fit a polynomial type function is introduced.

Conventional deinterlacing methods tend to yield undesired results in horizontal edges and high frequency areas. To address these problems, the proposed method uses different interpolation methods based on motion types. We first apply motion estimation and intrafield interpolation in the spatial domain. Second, a new interfield interpolation technique is performed. Finally, we selectively apply motion-compensation deinterlacing or repeat the new interfield interpolation technique. Experimental results show that the proposed algorithm provides noticeably improved performance compared to existing deinterlacing algorithms.","PeriodicalId":205589,"journal":{"name":"2007 2nd International Workshop on Soft Computing Applications","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115382199","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}
