It was impossible to have dynamical adjustment according to the density of network nodes. This article applied the percolation theory to optimization of broadcasting schemes in MANET. We put forward a new optimal algorithms, an optimized probabilistic broadcasting of MANET for percolation theory. We adopted the directional forwarding method, nodes forwarded the message with the critical probability which could just connect all network. Through mathematical reasoning and NS2 simulation, it shown that the algorithm significantly improves the data packet delivery ratio, average delay and other performance, and greatly enhances the utilization of node energy.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115439122","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 application of ‘cyclone separation theory’ is a fine method to improve separation efficiency. Computational fluid dynamics (CFD) is one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. With the simulation, some regularity would be discovered by a series of experiments that the angles (a) between two inlets of compressor separator were used different magnitude, the results showed that the separation efficiency was obviously affected by the location relation of the two inlets. Finally, the optimum parameters would be obtained to improve the separation efficiency for the compressor separator.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"99 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124109353","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}

To improve the precision and real-time of the hardware-in-the-loop simulation system, the High Level architecture(HLA) is used to construct a new hardware-in-the-loop simulation system. Firstly, we give a brief introduction to HLA and apply HLA to the hardware-in-the-loop simulation system. A simulation support software developed according to the specifications of HLA interface, RTI provides a number of interconnected simulation services and serve as the basis for the HLA simulation system to do layer management and extensible distributed simulation. The whole simulation system is considered as a federation and distributed into several federations to carry out the distributed simulation. We reach the conclusion that the problems for the practical application of HLA to a large-scale interactive simulation system will be solved by enhancing the algorithm and performance of RTI software.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"305 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124282669","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}

Traditional data integration techniques are no longer valid in the face of such heterogeneity and scale, and the integrated interfaces can become too complicated for ordinary users to use. In this paper, we propose a novel keyword-based user interface system EasyUI for achieving web-scale data integration and easy to use for ordinary users. Dealing with heterogeneity on the web-scale presents many new challenges. We proposed new methods to address these challenges, i.e., indexing schemata terms, data values, and domains features of the Deep Web, processing user input, mapping the user query to domain that the user query most likely corresponds to, and translating the user query into candidate structured queries for the domain. Our experiments show that EasyUI performs effectively.","PeriodicalId":386083,"journal":{"name":"2011 International Conference on Mechatronic Science, Electric Engineering and Computer (MEC)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124355944","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}

Using Computer Aided Engineering (CAE) modeling, the performance of the energy absorber and lower stiffener was analyzed for knee bending angle, tibia acceleration, and knee shear displacement, and then the improvement of bumper structure for lower leg protection is given through a combination of material properties and design within current styling and packaging space.
