But there are some insufficiencies in the definition of the fuzzy belief function and the combination rule on fuzzy sets of the D-S evidence theory. This paper describes a new definition of the similarity degree between two fuzzy sets and the improved extension combination rule of the evidence theory on fuzzy sets. It also presents the corresponding mathematical proof to validate the improved combination rule. Compared with other generalizing combination rules, the results of the numerical experiments show that the new combination rule in this paper can acquire more changing information to the change of fuzzy focal elements more effectively, and it overcomes the insufficiencies of other existing combination rules and enhances the robustness of fusion decision systems effectively.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128045931","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 order to correctly focus on the correct aspects of embedded system design, be it hardware for electrical engineering students, or software for computer science students, seamless connectivity between the hardware and software aspects needs to be provided. One approach to provide students from both fields with practical experience is to develop a transparent bridge between the hardware and software layers of the embedded system design. In this paper we demonstrate a universal serial bus/serial peripheral interface (USB/SPI) transparent bridge to interface an embedded system to a personal computer. The bridge consists of a hardware module that transmits the embedded system data through SPI to a PC using USB. A device driver for the USB/SPI bridge provides a straightforward application programming interface to the embedded system. The bridge can aide students studying embedded system design and students studying computer software development to collaborate on design projects.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133533691","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 the RAL algorithm, anchor nodes can transmit beacon signals at different power levels, which divide the possible transmission ranges of an anchor into a circle and multiple rings. The intersection of circle or rings of all the anchors heard by unknown node forms restricted-area I. In addition, we utilize all the perpendicular bisectors of the line which connects each pair of anchor nodes to obtain restricted-area II. Based on the restricted-area I and restricted-area II, we can calculate valid intersection points, and take average value of all these points as the estimated location of the unknown nodes. The proposed algorithm is range-free and energy efficient. Neighboring sensor nodes do not need to exchange information. Each sensor node only relies on information of anchors it heard to compute two kinds of restricted-areas and estimates its location. Simulation results show that the proposed algorithm has less estimation error than Centroid, Convex and CAB localization algorithms.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115640993","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}

Trust strategies may involve investigating user reputation or directly using transitive reputation to form the Web of Trust. We suggest an approach that takes advantage of both strategies without increasing the cost of investigation. Several systems nowadays form what we call ldquouser Web communitiesrdquo. In these communities, reputation related to different contexts needs to be exchanged. The perception, calculation and interpretation of this reputation differ from one community to another. We propose the development of reference models to diminish the distance between these multi-perceptions. We also propose the use of reputation centers to facilitate reputation transfer and highlight the importance of their role in analyzing attacks on reputation.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124365879","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}

Thereby, the methodology case-based reasoning is described to develop a decision support system for the interpretation of measurement results of bridges. Case-based reasoning is a cyclic problem solving method whereby already known knowledge about bridges is stored in form of cases. The system uses these cases to help the engineers in interpreting measurement results. Each bridge has different dynamic parameters. Therefore, analysis and interpretation of the raw datais very time-consuming and cost-intensive. Furthermore, the interpretation by human experts is done in a subjective way because each engineer has different concepts and experience in the interpretation of bridge measurement data. On this account, there is a need for an intelligent decision support system to support engineers in interpreting measurement results and making decisions.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124412409","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 bearing only target tracking, the basic parameters defining the target motion is estimated through noise corrupted measurement data.

In this work, a new optimization algorithm, namely Big Bang - Big Crunch algorithm is shown to fit this problem.

Ideally, samples should be independent and uniform. The restrictions of a distributed environment, however, introduce various dependancies between samples. We review gossip-based sampling protocols proposed in previous work, and identify sources of inaccuracy. These include replicating the items from which samples are drawn, and imprecise management of the process of refreshing items. Based on this analysis, we propose a new protocol, Eddy, which seeks to minimize temporal and spatial dependancies between samples. We demonstrate that these changes lead to a better sampling service by showing, through simulations, that using Eddy improves the accuracy of a network-size estimation algorithm that uses the random samples from the protocol.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132197391","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}

The key attainment is the ability to perform a late binding of service compositions, i.e., an allocation of actual services to service place holders during run-time. However, this attainment is limited to the binding of services and cannot operate on the service composition plans itself. Moreover, many service composition representations do not consider the realtime behavior of single services, failing to address a key need of service compositions within dynamic environments that are characterized by a high node mobility. Within this paper, we introduce a service composition model based on a bipartite graph representation that enables the rapid modification of already existing service composition plans. Here, the workflow within a service composition is modeled with a timed automaton while a labeled digraph ensures the correct flow of data between the single services.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122129053","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}

Load balancing is considered to require uniform storage access by file replication. We then define the load index as the storage access ratio. In the proposed method, each peer autonomously regulates the file replication probability to uniform storage accesses as thermal diffusion phenomena. Simulation results reveal that the proposed method can control the file sharing network to balance loads while dynamically adapting to change of storage accesses that is caused by change of popularity trends, and therefore keep load balancing performance stable. In addition, the proposed method achieves greater adaptability to sudden changes in storage accesses than our previous method.","PeriodicalId":367280,"journal":{"name":"2008 The Third International Multi-Conference on Computing in the Global Information Technology (iccgi 2008)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124980652","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}
