E-learning systems are increasingly becoming an important part of the strategy for delivering online and flexible e-learning. The main advantage of e-learning is the opportunity for students to interact electronically with each other and their teachers during forums, on discussion boards, by e-mail and in chat rooms. Though recognizing that the world at large will continue to use terminology in different and often ambiguous ways, the term of virtual learning environments (VLE) is used to refer to the on-line interactions of a variety of kinds that take place between learners and instructors. There are many pieces of software available that provide VLE systems, both commercial and open source software (OSS). One such system that has been gradually gaining worldwide popularity is known as Moodle. This paper focuses on this platform and on a comparison between VLE (Moodle) and other VLE systems in order to discover their strengths and limitations. The comparative study is in two phases. The first phase is based on the features and capabilities of VLE tools and the second phase is based on the technical aspects of the VLE platforms.","PeriodicalId":414800,"journal":{"name":"2008 12th IEEE International Workshop on Future Trends of Distributed Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126138978","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}

{"title":"Reliability Analysis of Component-Based Software Based on Rewrite Logic","authors":"Dong Wang, Ning Huang","doi":"10.1109/FTDCS.2008.15","DOIUrl":"https://doi.org/10.1109/FTDCS.2008.15","url":null,"abstract":"Along with the development of object-oriented technology, component development is gradually extended to commercial off-the-shelf (COTS) components and component-based software development (CBSD) has gradually become the dominant orientation of the field of software engineering. The claims of high reliability need further investigation based on reliability analysis techniques that are applicable to component-based applications. This paper introduces a new reliability analysis technique applicable to high-level designs. The technique is named reliability analysis based on rewrite logic (RABRL). RABRL is specific for component-based software whose analysis is strictly based on its operational profile and specification. Specification based on rewrite logic can be executed with the help of rewrite technique of Maude, driven by test cases designed from the operational profile. By analyzing the execution process with statistics, we can get the transition probability between components and expected number of visits to components approximately. The paper also adapts the probabilistic model \"component-dependency graph\" (CDG) proposed by Sherif M. Yacoub to model the component-based software, which is named \"adapted component-dependency graph\" (ACDG). ACDGs are directed graphs that represent components, component reliabilities, transitions, and transition probabilities. Based on ACDGs, an algorithm is presented to analyze the reliability of the application as the function of reliabilities of its components. A simple case study illustrates the applicability of the algorithm. The RABRL is also used to identify critical components.","PeriodicalId":414800,"journal":{"name":"2008 12th IEEE International Workshop on Future Trends of Distributed Computing Systems","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131396797","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}

Energy Efficient Detections of Critical Events in Wireless Sensor Networks 无线传感器网络中关键事件的节能检测

Immediate measures can subsequently be taken to remove associated risks timely. However, there is no successful work for detecting such critical events energy efficiently. In this paper we propose a novel approach. A fully distributed algorithm is designed, in which each sensor makes the decision purely locally. The elegance of the algorithm is that a global network behavior can be presented based on individual node actions, without a central authority to coordinate. This effectively reduces unnecessary sensor reports for network-wide coordination. Our proposed algorithm, called MEES, has the property of a zero event-missing rate, i.e., critical events are always detected. There is a trade-off between the energy cost and the false positive. Simulation experimental results show that MEES is more appropriate for large-scale WSNs with highly dynamic sensing environments. The energy cost can be saved up to 70%.","PeriodicalId":414800,"journal":{"name":"2008 12th IEEE International Workshop on Future Trends of Distributed Computing Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123007129","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}

Those systems however fail in controlling the location of subjects along the period of use of the objects and this can lead to security breaches. To ensure a stronger protection of objects, a continuous control over the movement of subjectsis thus needed. To address this requirement, we have developed GEO-RBAC_C a location-based access control model supporting continuous usage control capabilities. In the paper,we first present the basic concepts of the model and then discuss how the continuous control can be actually enforced.","PeriodicalId":414800,"journal":{"name":"2008 12th IEEE International Workshop on Future Trends of Distributed Computing Systems","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127868189","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}

Activities in the preparative development departments of leading german car manufactures show the challenges by the development of mechatronic products and the need for simulation of mechatronic systems. For an early validation of vehicle functionalities special simulators are used for specific domains - like mechanics, electronics and software. To provide timely simulation and review for complete mechatronic components, these simulators need first to be coupled with one another, to have an interdisciplinary behavior. The objective of our approach is the development of a distributed framework for cooperative multi-domain simulation, validation and debugging of complex mechatronic system behavior. The feasibility of our approach is shown by a case study of an automotive mechatronic system.","PeriodicalId":414800,"journal":{"name":"2008 12th IEEE International Workshop on Future Trends of Distributed Computing Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-10-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129221155","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}

This approach consists of the establishment of performance models for SBS through controlled experiments, the development of QoS monitoring and adaptation (M/A) modules based on the performance models, and the validation of ASBS design through simulations.
