By using social media and access records of their users, the proposed system determines their risks. Also, it monitors the restricted area through setting them and notifies the administrator as soon as the intrusions are detected. So, it will provide a control situation for administrator in real time and can detect the risky moments that may occur in advance. Therefore it can reduce the probability of risk of security penetration. Also, since it receives the control situation and provides real-time control screen via smartphone, it is possible to improve the convenience of intrusion management in a very fast and effective way.","PeriodicalId":306280,"journal":{"name":"International Journal of Computer Theory and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124105734","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}

To the authors’ knowledge, this has not yet been studied by other researchers. Dynamic in the context of this paper is defined by the ability to persistently simulate Time Dilation effect based on specific parameter that can be controlled by user/viewer in real-time interactive simulation. Said parameter is the value of speed from acceleration and deceleration of moving observer. In \u0000relativistic environment, changing the speed’s value will also change the Lorentz Factor value thus directly affect the Time Dilation value. One can simply calculate the dilated time by using Time Dilation equation, however if the velocity is not constant (from implying Special Relativity), one must repeatedly calculate the dilated time considering the changing value of displacement/distance and time. This paper discusses the proposed method by dissecting Time Dilation equation and relates it to computational method available nowadays in order to dynamically calculate and ultimately simulate Time Dilation \u0000effect in relativistic virtual environment.","PeriodicalId":306280,"journal":{"name":"International Journal of Computer Theory and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130140145","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}

To deal with this problem many authors have suggested family of estimators of population parameter. But in the case of generalization of these estimators, estimation of optimum values is a problem. Some authors can define estimator replacing the unknown parameters by their sample estimates. To get the optimum estimator, one need to solve complex mean square error equation with many parameters and nonlinear constraints. In this study we have tried to get these optimum parameter in stratified random sampling using genetic algorithms and sequential quadratic programming. A numerical example is also done to compare these algorithms. The results show that genetic algorithm is more efficient than sequential quadratic programming to solve the complex model with more parameters under non-linear constraints.","PeriodicalId":306280,"journal":{"name":"International Journal of Computer Theory and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124797969","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}

WOA extends SOA to web-based applications. The architecture hides the protocol complexity in the application state and provides simpler methods for the deployment of interoperable web services. However, this pragmatic and effective approach has only been rarely implemented, limiting the body of formal knowledge and support available to enterprises which want to exploit this profoundly useful and simple way of developing interoperable systems. In this paper, we describe the development of a novel customer-centric collaborative commerce platform (WCCP) on WOA in a virtual environment. The classification from the United Nations Standard Products and Services Code (USNPSC) was adopted to achieve the interoperability between differential enterprises.","PeriodicalId":306280,"journal":{"name":"International Journal of Computer Theory and Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129818591","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}
