The rail is modelled as elastically supported continuous beam with lumped masses. A vehicle is approximated as a discrete system consisting of three rigid masses connected with linear elastic springs. Dissipation mechanisms in the system are modelled with the linear dashpots. Two basic assumptions that are used are: a) the Euler-Bernoulli beam theory and b) the separation of the wheel from the rail is not permitted. The system of differential equations of motion is solved by an implicit version of step by step method based on the direct integration technique. The algorithm is conceived on the first order predictor - (re)corrector method. The contact condition is modelled by the force method. Results of the calculations are compared with the results of measurement on the tram track. Numerical predictions for displacements and accelerations are in good agreement with the experimental findings","PeriodicalId":198751,"journal":{"name":"First Asia International Conference on Modelling & Simulation (AMS'07)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678004","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}

Firstly, this paper presents some of the difficulties (e.g. imprecise data) in measuring e-readiness of a country. Secondly, this paper presents a fuzzy logic model of a new tool for measuring e-readiness, as fuzzy logic is well suited for working with imprecise data. Finally, this paper presents a hybrid tool for measuring e-readiness. The hybrid model uses fuzzy logic together with array-based logic. The main reason for proposing the hybrid tool is to reduce the size of the fuzzy rules base","PeriodicalId":198751,"journal":{"name":"First Asia International Conference on Modelling & Simulation (AMS'07)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129143126","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 NPP plant life-cycle tends to reach 50-60 years, while that of the I&C system is only 8-10 years. Not only the systems become obsolete: spare parts for the old system are practically nonexistent. Putting into operation reliable, thoroughly tested, verified and validated, approved by the authorities new systems could significantly increase the outage time of the units. However, about 90% of the work can be done off-line, by means of full scope replica simulators, and in the same time the operators become trained to these new systems, too. Taking this approach the refurbishment does not increase the outage time needed for refuelling and repair, at least not significantly. The paper describes this methodology in detail","PeriodicalId":198751,"journal":{"name":"First Asia International Conference on Modelling & Simulation (AMS'07)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128764580","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 last almost two decades practically every element of the simulator has been upgraded, replaced because the fast development of the computer techniques made the solution a great amount earlier unsolvable problems possible. Moreover, the requirements against the simulator have also changed. Originally the simulator was used only for training the operating personnel of the Paks Nuclear Power Plant, but now it is used as a \"test bed\" for new systems prior their installation on the real plant, too. The first such testing was the replacement of the Reactor Protection System with a new computerized one. For this reason the scope of the models had to be extended to cover the severe accidents, which needed a much more powerful simulator computer than the original one. The outdated control room interface system had to be replaced by a new one, because spare parts became unattainable and its service required very high cost. Only the instructor's system remained in its original form. Now the old Instructor's system has been replaced as well. All the old functions were realised by convenient full-graphic Man-Machine Interface tools.
