They are driven with periodical and time variable signals - especially sawtooth, triangular, sine wave or signals with special variations. We approach in this paper the rejection of the effect of disturbances in order to improve the tracking performances of the GS. The control solution proposed in the paper is based on the extension of the existing control structure with an additional loop, with an additional controller PID-Ll type, which will ensure better speed response and good immunity to constant disturbances which can affect the servo system.","PeriodicalId":304729,"journal":{"name":"2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"97 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121840128","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}

Work presented within this paper describes the GHSOM (Growing Hierarchical Self-Organizing Maps) algorithm for clustering of text documents and proposes the design and implementation of distributed version of this approach. Proposed implementation is based on JBOWL framework as a base for text mining. For distribution we used MapReduce paradigm implemented within the GridGain framework, which was used as a cloud application platform. Experiments were performed on standard Reuters dataset and for testing purposes we decided to use a simple private cloud infrastructure.","PeriodicalId":304729,"journal":{"name":"2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132093502","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}

Everyday car accidents, long queues and stop-and-go waves are introduced by the driver's behavior. In this work, an effective control algorithm for emulating a bottleneck situation on a highway is presented using a set of mobile robots that can be used to educate young control engineers. We use a combination of i) an in-line leader-follower formation and ii) a formation with two followers for one leader i.e. a triangular formation. Both formations are implemented using distance and angle measurements from image processing algorithms and speed measurements from optical encoders. A cascade PI-P controller is used to stabilize the system. The challenge of the current implementation stands in the fact that there is no communication between the robots.","PeriodicalId":304729,"journal":{"name":"2013 IEEE 8th International Symposium on Applied Computational Intelligence and Informatics (SACI)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133001023","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}
