The novel algorithm is based on building a sublattice of a minimal number of double indices. A double index is a data structure that combines the indices of two relations and is built by a hashed-based join algorithm. The double index is divided into join buckets with the same hash function value. The algorithm then joins buckets with similar hash function to produce joined buckets. These steps are used to build the complete join index of the two relations. The time complexity required to build the join index of two categories is in the order of m log m where m is the size of each category. The time complexity to join all buckets is of the order of n log m. The join index is used to materialize the joined relation if required. Otherwise, it is used along with other double indices of other relations to build a sublattice to be used in multi-join operations with minimal I/O requirements. The sublattice of the double indices can be fitted into the main memory which further reduces time complexity of the multi-join algorithm. The main advantage of our technique is when used in intensive multi-join dominant computational environment.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128664251","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}

In spite of many research efforts in the visual guidance of autonomous robotic wheelchairs have been devoted to road edge detection, the after-detection process, especially the physical interpretation of what had been detected, needs more investigation. In fact, there is a wide gap between the scene model built based on image processing algorithms and the physical model of the environment where the robotic wheelchair progress. In this paper, the subjective interaction between the scene model and the world model is investigated, and a visual control scheme for robot guidance is proposed that minimizes the model error induced by processing raw image data. The involved control system includes a fuzzy control system which uses the knowledge base information and the scene model to control the robot motion. On the other hand, the fuzzy control system is finely tuned through feed-backing mean square errors between the scene model parameters and the knowledge-base data. Finally, the fuzzy controller uses results of these calculations to home the robot on the planned path. This paper also shows the principle of this system and the simulation results confirming the feasibility of the approach.","PeriodicalId":189871,"journal":{"name":"2008 First International Conference on the Applications of Digital Information and Web Technologies (ICADIWT)","volume":"117 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134575297","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}
