A Computational Fluid Dynamics (CFD) based comparison of optimal thrust and efficiency generation among four typical fin undulating swimming models with different amplitude envelopes as well as the fin morphologic have been discussed independently. Here, we seek to complement those studies by considering the influence of reciprocal effect between swimming models and morphologic on the fin propulsion performance. The pressure distribution on fin surface was computed and integrated to provide fin forces which were decomposed into lift and thrust. From the simulation, we conclude that: the compliance of the distribution mode of fin outline with amplitude envelope can generate best propulsion effect and fastest swimming speed. These computational results are very useful for optimal design of our undulating robotic fin.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132159827","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 this paper, we consider the multicast routing and wavelength assignment problem(MC-RWA) in multi-hop optical WDM networks, where requests arrives one by one. Specially, we first analyze this problem under the objective of minimizing maximum hops, an efficient MC-RWA algorithm was proposed in this case. But for minimizing the total number of wavelength conversions, the problem turns out to be NP-hard, hence we propose an efficient approximation MC-RWA algorithm. At last, combine the the two objectives, we propose a bi-factor approximation algorithm to minimize the total wavelength conversions and the maximum hops in the system simultaneously.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131686800","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 certain experimental methodology including specimen's preparation of the original state frozen soil, the precrack of frozen soil specimen, the measurement of critical crack length using dye penetrant technique, non-linearity correction factor determination and relationships between non disturbed frozen soil and disturbed frozen soil, etc. has been studied in the paper. There exist obvious differences of fracture toughness between undisturbed and disturbed soils although the samples are tested under the same conditions of initial water content, dry density and temperature.

Nowadays, many enterprises like IBM have realized that manpower is one of the most important and expensive inputs for different constituents of the supply chain. It's time to refocus and apply the lessons learned from optimizing your product lines to optimizing your human resource. To maintain sustainable development and to cope with the ever-changing world, researchers should study the manpower situation and navigate training needs in various industries. Hence, it is critical to optimize, through a series of strategies, policies, processes and tools, what may be called the workforce supply chain. We try to propose a preliminary network optimization model for professional service firm revenue management under an uncertain environment. Multifunctional staff's capacity allocation is emphasized. The network optimization is in a stochastic programming formulation so as to capture the randomness of the unknown demand.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124427399","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}

With increasing density, the lane changing region is alterable around the bus.

Although some research has been conducted, the behavior of DMs and the dependence among criteria are seldom considered in emergency decision making analysis. In this paper, a risk decision method for emergency response based on cumulative prospect theory (CPT) is proposed by extending the CPT to dependent criteria. In the method, firstly, a value function with two variables is constructed by extending the value function of CPT to two dependent criteria. Then, the weighting function of CPT is used to determine the weights of possible results concerning each alternative. Thus, prospect values of alternatives are calculated by aggregating the values and weights of possible results. Furthermore, overall prospect values are obtained by aggregating the prospect values and costs of alternatives. Moreover, a ranking of alternatives is determined according to the overall prospect values. Finally, a potential application is used to illustrate the feasibility and validity of the proposed method. Introducing the behavior of DMs and the dependence among criteria into emergency decision making analysis would make the results of decision analysis more consistent with the institution of DMs, and will enhance the application value of the proposed method.","PeriodicalId":210815,"journal":{"name":"2011 Fourth International Joint Conference on Computational Sciences and Optimization","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125856993","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}
