This is particularly true for the simulation of complex systems where the computational resources needed considerably increase with the model resolution and with the number of simulated entities. The development of such simulation systems, however, requires extra efforts compared to the conventional local ones. Example extra efforts are learning how to use the Distributed Simulation (DS) Standard (such as HLA) and the development of extra software for the synchronization and communication between the local and distributed environment. In this paper, we address the problem of defining a simulation language that can transparently support the development distributed simulation systems, by making the use of the DS standard transparent and also reducing the amount of extra software. The HLA transparent language we introduce is named jEQN, being Java-based and dealing with Extended Queueing Networks domains. The language approach, however, can be easily extended to any other DS Standard and modelling domain.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129536653","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}

Under the standard of extensible modeling & simulation framework (XMSF), web technology has been applied to distributed simulation more and more. The research on the Web-based statistical & evaluation method has become the new tide in simulations. This paper introduces the deficiencies of traditional statistical & evaluation method first. Given the deficiencies, the Web-based real-time statistical method is put forward. Then the work principle and the key techniques which include design of statistical data agent (SDA), design of real-time statistical calculation module and Web-based statistical data publication are illustrated in detail. Finally, it gives an application of the Web-based real-time statistical method and summarizes the characters and the future development of the new method.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123859177","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}

Because these machines are capable of providing high pressure along with variable loading, they are favored for many gas process applications. The crank-shaft is a very important part of the reciprocating compressor, but suffers from the high fraction defective of finished products, hence a high performance of the lubrication resulting from fluid dynamics is strongly demanded. The structure of the crank-shaft is normal but the oil hole in the crankshaft is so complicated that the actual structure of the crank-shaft is different from the designed and the oil-film develops incompletion. All of these will cause locking problem. So we want to design the structure of the oil-hole to improve the lubrication between the crankshaft and the bearing. We use CT (computed tomography) scanner to scan the crank-shaft, and re-created crank-shaftpsilas model. Then predict the stress and deformation of the crank-shaft. The model analysis provided valuable theoretic basis for the improvement of the compressorpsilas crankshaft. Finally, we improve the structure of the crank-shaft, the oil-film develops easily than the previous one, and itpsilas high quantity to product.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123870044","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 evaluate a GPS receiverpsilas performances, a simulation platform build on Matlab has been developed by this research. This platform includes four elements: user interface, GPS signal simulator (intermediate frequency, IF), civilian (C/A) software receiver and noise generator. Design and implementation of the platform are discussed in details in this paper. Firstly, a mathematical model of intermediate frequency (IF) GPS signal simulator is introduced. After that, methods of determining visual satellites and computing transmission time by using existing ephemeris are also discussed. Secondly, key algorithms of the software receiver, including acquisition and tracking, are presented. Finally, an experiment is demonstrated to test the validity of this platform. The close correspondence between pre-designed user trajectories and position results of the software receiver certifies the validity of this platform. Compared with hardware simulation, this platform possesses more effective and flexible. The performances of the receiver can be tested completely by changing different scenes of signal simulator. All key techniques of this platform are modularized and coded with Matlab language. It is easy to understood and used. In this sense, this simulation platform can be an ideal tool for new beginners of this field to master GPS principles.","PeriodicalId":217503,"journal":{"name":"2008 Asia Simulation Conference - 7th International Conference on System Simulation and Scientific Computing","volume":" 18","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113952204","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}
