Voltage control methods in power systems needs proper coordination among reactive power resources and conventional volt/var control equipments. In this work, potential reactive power resources are investigated and then, reactive power output of renewable DG units and controllable loads along with operation of conventional voltage controllers are optimized using a centralized control scheme. Considering the variability of demand and generation, the controller would minimize voltage variations in distribution network. The operation of distribution network is optimized using genetic algorithm (GA). The method is implemented on a sample 14-bus distribution network and the results show the improvement of voltage profile of different buses.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115084039","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}

However for a developer or team working on any network project who need to perform DPI, there is always the issue of using a third party source which may involve added cost or implementing it themselves which requires time and study of protocols, signatures and the nuances of pattern matching. The paper proposes a solution to the above problem using an adaptive grammar generation algorithm. This method reduces the entropy among similar results given by different patterns. Immense customizability is the foremost advantage of this method. Existing grammars for new signatures can be combined into a single grammar easily rather than new grammars be generated from raw target strings. The paper, thus, looks to limit the detailed knowledge requirement for the design of signature detection procedures and in doing so re-use existing procedures which have been thoroughly debugged and tested.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125263665","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 this paper, we propose an event notification and intelligent inference system based on information gathered from the profiles of registered users over the Web. Our model uses parallel workers to fetch and incrementally update the changing user data through the Web. The raw data is transformed in a canonical manner for correlations to generate notifications to a user about important events in the life of related people. We make use of asynchronous distributed task queuing, which uses an open source message-oriented middleware as a broker for message passing between our application server and the multiple background workers. This helps achieve a high degree of parallelism and scalability. A value added by this model is the higher quality of user experience provided by timely notifications. The model would also benefit suppliers catering to users' needs for various life events by promoting e-commerce and soon m-commerce. A different set of parallel workers could be conceived to capture the data about suppliers and their offers to carry out matching.","PeriodicalId":131364,"journal":{"name":"2011 UKSim 5th European Symposium on Computer Modeling and Simulation","volume":"148 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130123996","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}
