A modified Newmark β method is developed for solving the nonlinear dynamic equations. Numerical results show obvious nonlinear behavior for air-bearing sliders with ultra-low flying heights. The length of the pressure centers at the trailing edge and the leading edge are chosen as the parameters to be optimized. Based on the traditional simplex method, a modified simplex method is presented. The dynamics are compared between the optimized slider and the original one both in time and frequency domain. The results show the optimized slider has better dynamic property than the original one, and the other parameters could also be optimized by adjusting some objective function module.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"217 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130361237","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 solve the current issues faced in WiMAX network, and improve QoS demand, a new mechanism, ODBA is designed. Tt is an on demand bandwidth allocation mechanism for WiMAX. ODBA depends on the different characters of different service flow, to adopt different schedule algorithm. Further more, DL/UL direction of different service flow is scheduled by BS and SS respectively. The performance of ODBA mechanism and its behavior are evaluated, analyzed and compared with other algorithms and those without ODBA in WiMAX network. The performance has been simulated using OMNeT++ simulator in metrics of network throughput. The simulation results show that the ODBA mechanism has higher network performance than without ODBA in WiMAX network.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125408902","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 common way to obtain the sag value is to lookup the curves provided by the design departments, but the standard sag obtained by this way is prone to make a personal error. Aimed at above problems, this paper proposes a computing method of standard sag for overhead lines based on iterative technique. The method establishes a mathematical model by computing theory of the stress sag. The model makes use of high-speed iterative of computer to compute standard sag of any given span through state equation of stress and judgment principle of control climate conditions. The method possesses many advantages, such as, clear thinking, easy to understand and without considering complex logic judgment to solve critical span. Finally, an example proved that the method to solve the stress is rapid and high accuracy.","PeriodicalId":271757,"journal":{"name":"2010 2nd International Conference on Computer Engineering and Technology","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126012241","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}
