The facts and rules of knowledge bases at the back end of decision support systems represent beliefs that are subject to revision. Belief revision is called for whenever an inconsistency occurs. Inconsistency may be due to an update that contradicts extant beliefs, or may have remained hidden before being uncovered. In particular, inconsistency is likely to appear in decision support systems based on distributed, mutually independent knowledge sources. If consistency is modeled by business rules, in the form of integrity constraints, then inconsistency can be measured, by sizing either the violated instances of constraints or the beliefs that cause constraint violations. Measures that quantify inconsistency enable a distinction of different degrees of integrity violations, and thus a relaxation of the intolerant all-or-nothing attitude of classical logic toward consistency. They also provide a logical foundation and justification of maintaining and reasoning with beliefs that possibly are inconsistent, without risking to lead to decisions that suffer too much from contradictory sources.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116790334","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}

They have many potential applications for both civil and military tasks. However, the unattended nature of WSNs and the limited computational and energy resources of their nodes make them susceptible to many types of attacks. Intrusion detection is one of the major and efficient defence methods against attacks in a network infrastructure. Intrusion Detection Systems can be seen as the second line of defence and they complement the security primitives that are adopted in order to prevent attacks against the computer network being protected. The peculiar features of a wireless sensor network pose stringent requirements to the design of intrusion detection systems. In this paper, we propose a hybrid, lightweight, distributed Intrusion Detection System (IDS) for wireless sensor networks. This IDS uses both misuse-based and anomaly-based detection techniques. It is composed of a Central Agent, which performs highly accurate intrusion detection by using data mining techniques, and a number of Local Agents running lighter anomaly-based detection techniques on the motes. Decision trees have been adopted as classification algorithm in the detection process of the Central Agent and their behaviour has been analysed in selected attacks scenarios. The accuracy of the proposed IDS has been measured and validated through an extensive experimental campaign. This paper presents the results of these experimental tests.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"2019 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127173615","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 past research, we have constructed tele-immersive environment with tiled display wall to realize high-realistic tele-communication. However, the video image captured by a single small camera is difficult to display as video streaming with realistic high-resolution on tiled display wall, because there is a limit in the display resolution of video image captured by a single camera. In response to these issues, we have constructed the tele-communication environment to display a ultra-resolution video image on tiled display wall by multi-transmitting each video which captured by four cameras with tiled display wall. However, the adjustment of each camera position is necessary to display a high-resolution video by combination of boundary area between each captured video, the effective camera setting is not make clear. In this paper, we have conducted experimental study the effect of position setting of multiple cameras on a high-resolution video in telecommunication environment with tiled display wall.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123710276","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}

Reducing the execution time of some very costly instances and/or solving new unresolved instances remain a challenge. The PFSP consists on scheduling n jobs in m machines with make span criterion. Our approach to resolve this problem is based on a parallel distributed solution based on Branch and Bound method. In a previous work, we proposed a first algorithm called GAUUB that distributes the tasks among all processors while updating the new current better Upper Bound (UB). This algorithm GAUUB allowed us, in one hand, to reduce significantly the run times of several benchmark instances and on the other hand, to resolve new instances. In this work, we propose another version of this algorithm (called GALB) that improves the load balancing of tasks among the available processors. Our objective is to have all processors terminating at almost the same time and such that improving run time. In this paper, we will present detailed description of GALB as well as an exhaustive evaluation study based on the well known Tail lard's Benchmarks and performed on the French national grid (Grid'5000).","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115072483","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}

Service offerings of this type have appeared in the recent years, covering a need for dynamic and on-demand creation of such data analytics frameworks. The aim of this paper is to provide a mechanism for offering such virtual clusters as a service, with built-in intelligence functionalities for efficient management. The target of these mechanisms is to predict future demand of the files in the HDFS cluster and dynamically manipulate the according replication factor for availability purposes, in order to improve performance and minimize storage overhead. To this end, real data have been utilized as a dataset input to the prediction framework, based on Fourier series analysis, due to the latter's ability to capture different periodicities that can influence service usage. Multiple time-step ahead prediction is performed in order to enable proactive management (e.g. suitable replication strategy). We describe the framework's architecture, necessary modifications to the client side of Apache Hadoop for data logging and the results of the applied method on two real world datasets.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128223561","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}

Therefore, computer center administrators of universities must overcome the increasingly expensive effort of providing up to date facilities. National Technical University of Athens (NTUA), is a technical university, where students gain hands-on practical experience in computer laboratories as an essential complement to lectures they attend. NTUA's computer laboratories have to be highly flexible and configurable for a variety of applications: from the implementation of a wide range of computer networks, to the incorporation of computer-aided engineering/manufacturing(CAE/CAM) software. Traditional system and network administration practices are usually complicated in terms of configuration and maintenance and generally lack flexibility and scalability. We discuss the architecture of a personalized cloud-based solution for the specific needs of educational institutions. The goals are high utilization of resources and minimization of the administration effort needed to maintain physical laboratories, achieved by the centralized integration of computing, storage, network and application facilities. Such a centralized integration utilizes the high-speed network interconnections of the university campus and takes advantage of the broadband technologies that are globally available outside of it. We introduce NTUA's \"Central Cloud Front\" (CCF) to prove the concept of the proposed architecture.","PeriodicalId":209674,"journal":{"name":"2013 Eighth International Conference on P2P, Parallel, Grid, Cloud and Internet Computing","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127038873","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}
