The state of charge (SoC) of battery, charging time and arrival time to charging station are considered. After obtaining a charging profile, a voltage profile is analyzed by DIgSIENT PowerFactory. Subsequently, an impact analysis of PEV fast charging stations to voltage profile of the Provincial Electricity Authority (PEA) distribution system is carried out. The simulation results show that charging station affects changes of voltage profile and voltage drop in the distribution system. In addition, the presented method is applicable, even if the rated charging power of charging station is changed, an approach presented in this research can also be applied to analyze the impact.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"15 9-10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116750231","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}

Thus, if contingency occurs, it can be ensured that all constraints such as generation limit, transmission limit and ramp rate will be satisfied. To solve the problem, quadratic programming is applied. IEEE 30 bus system is used as test system to show the ability of the proposed approach.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"230 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114750105","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}

With accurate forecasting, proactive measures can be appropriately applied on time to reduce both human and property losses. However, Thailand has insufficient meteorological data to apply the NWP model. In fact, the forecasting is done manually in Thailand. This makes the forecasting unreliable and time consuming, which leaves not enough time to prepare a good warning bulletin. To address these problems, this paper proposes an integrated short-range tropical cyclone track and intensity forecasting system by using only 11 features which were extracted from satellite images with improvement of the traditional statistical methods. The performance of the model is satisfactory, giving an average of 4.12 degrees of 6 hours, 12 hours and 24 hours track forecasting errors from best track data and the average errors is lower than traditional techniques by 14.16% on Mercator projection map and the average intensity forecasting errors of 6 hours, 12 hours and 24 hours lower than traditional techniques by 25.18%.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133883755","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}

One of the challenges faced by Java developers is the inability to determine the correct number of class dependencies. The ability to recover class dependencies would help developers to understand the design of an existing system prior to modifying it. Many Java dependency analysis tools for this purpose have been proposed, but few are able to analyze the dependency types associated with Java bytecode. In this paper, we propose a reverse engineering tool to extract the dependencies from a compiled Java program. The tool provides a visualization of the recovered dependencies in a form that facilitates the developer's ability to examine the classes and class relationships in the software system. The resulting dependency extraction capability will also enhance software maintenance and evolution. The results of experiments conducted with the intent of evaluating the proposed tool demonstrate both its accuracy and a few of its limitations.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134527884","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}

Furthermore, routing protocols have to work efficiently under constraints of limited bandwidth and energy. These challenge researchers to develop a suitable protocol for the networks. In this paper, we present a new routing protocol, which limits the number of message replications. In addition, a node should spread messages with lower probability if the messages are currently distributed in its local neighborhood. This increases an opportunity for a node to spread messages to other network areas. Simulation results show that our work can increase delivery ratio while maintaining low end-to-end delay and message exchange overhead.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125165827","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}

Existing networks require new technologies because the management of these networks is difficult and the traffic problems cannot be easily solved. These challenges have prompted the development of software-defined networks (SDNs). SDNs divide existing network structures into data planes, which manage data transmission, and control planes, which manage network controls. These planes enable easy, flexible network management or expansion through centralized structures. Specifically, SDNs efficiently control networks by monitoring network traffic or utilizing the state information of the connected switches. However, due to the characteristics of SDNs that centralize network management, specifically switch performance, controller overhead may increase, which may lead to problems throughout the entire network. This paper discusses these problems and proposes an algorithm that promotes efficient network management when the flows are replaced at the flow tables.","PeriodicalId":207985,"journal":{"name":"2015 7th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124541922","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}
