The accuracy of solution will be affected by the right selected of the weight function. The Cubic B-spline wavelet function has many good natures, such as recursion, local positive supported, multi-scale and the smallest compact supported. This paper attempted to study it as the weight function and design a practical algorithm of meshless. With the one-dimensional pole and two-dimensional plate structures as example, three functions which are Gauss function, the constructed Cubic B-spline wavelet function and Cubic spline function are studied as weight function in meshless methods. Through the comparison of approximate and exact solutions of displacement and stress, results show that the proposed Cubic B-spline wavelet function possesses high fitting solution based on multi-scale and good stability, while exploiting application area to select the weight function in meshless methods.","PeriodicalId":427481,"journal":{"name":"2010 Third International Joint Conference on Computational Science and Optimization","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132450932","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}

Although some methods have been used to estimate the parameters for Muskingum model, an efficient method for parameter estimation in the calibration process is still lacking. In order to reduce the computational amount and improve the computational precision for parameter estimation, a modified particle swarm algorithm (MPSO) is presented for parameter optimization of Muskingum model. The technique found the best parameter values compared to previous results in terms of the sum of least residual absolute value.

It has the advantage of incorporating a relatively simple and efficient form of mutation and crossover. However, the operator of DE is primarily based on floating-point representation only and is difficult to apply to binary-based optimization problems. In this paper, a modified binary differential evolution with a simple and new binary mutation mechanism based on a logical operation is proposed. The developed binary mutation strategy is suitable for dealing with discrete and parametric engineering optimization problems. Two different types of engineering problems consisting of optimal shape design of heat bonder and topology optimization of structure are used to illustrate the high viability of the proposed algorithm in engineering optimization.","PeriodicalId":427481,"journal":{"name":"2010 Third International Joint Conference on Computational Science and Optimization","volume":"131 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124252652","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}

Simulation results on a three-parallel-route network show that it is uncertain whether the information released by advanced traveler information systems (ATIS) can make the flow pattern evolve to a logit stochastic user equilibrium, which depends on the length of memory. If memory length is larger than a threshold value, the provided information drives the flow pattern to a stochastic user equilibrium state; otherwise, the logit stochastic user equilibrium is unattainable and the system evolution can not converge to a stable state. Furthermore, it is also shown that the fluctuation of traffic flow under full information exceeds that under partial information on the same route, when the length of memory remains unchanged.","PeriodicalId":427481,"journal":{"name":"2010 Third International Joint Conference on Computational Science and Optimization","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123995823","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}
