Nowadays, sustainable development is one of the most important issues that its social and physical aspects are strongly recommended. Formation of social sustainability depends on sustainable social relations, which in the field of urban design, emphasis on the space as a platform for the formation of these relationships is considered. On the other hand, the physical and spatial variables affect the responsiveness of environment, which influenced on the election and the presence of the people in outer urban spaces like streets. What is common idea in urban design is a direct relationship between physical environment and sociability of the streets. At the moment, in the cities, there are large numbers of the streets which aren't well prepared for presence of people despite of having high level of accessibility. Thus, a well-defined relationship should be exists between the accessibility rate and sociability of the streets in which if the accessibility rate excide from maximum desirable amount, a decrease will be observed in the sociability amount. The aim of this study provides criteria about physical design in relation to sociability amount of the urban streets. On this basis, fundamental research questions are: 1. How is the relationship between physical environment and sociability levels in urban streets? 2. How much access to urban streets is suitable with regard to social, socio — physical and spatial aspects? 3. What activities can support accessibility and sociability of the streets? The key problem is loss of urban activities in urban streets. Doing the above, identification of a practical and theoretical framework for measuring the function of urban street networks is the main findings of this study that the proposed framework considers the functions of streets in dynamic and static activities of people. Moreover, suggestion of the appropriate functions for streets according to the accessibility rate and expected sociability of streets is another outcome of this research. The research methodology is based on observation (gate observation, people following, and static activities), interview, and axial analysis in the case study of Malaysia.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87310714","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 method, Fast Transversal RLS algorithm is used. An Adaptive Temporal Filter (ATF) based on a Transversal form that pre-filters the interference before correlation is studied. This algorithm is designed to provide similar performance to the standard RLS algorithm while reducing the computation order. The adaptive algorithm used to adjust the filter coefficients is the FT-RLS algorithm. This algorithm has faster convergence and is independent of the gradient step size when compared to LMS, NLMS, RLS, QR-decomposition-based RLS and Sliding window-RLS algorithms. We present initial results on the performance of the described interference cancellation methods.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87437276","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}

A minimization problem is formulated that consists of finding the control voltage applied to a piezoelectric patch actuator which suppresses the dynamic responses of the beam at a specified terminal time with least control effort. The solution method is based on a combination of modal expansion and direct approximation approaches. The modal expansion approach is used to convert the optimal control problem of distributed parameter system (DPS) into the optimal control problem of a linear time-invariant lumped parameter system (LPS). A direct state-control parametrization approach is proposed where wavelets are employed to solve time delayed LPS. The operational matrices of integration and delay are utilized to reduce the solution of linear time-varying delayed systems to the solution of algebraic equations. An illustrative example is included to demonstrate the applicability and the efficiency of the proposed method and the results are quite satisfactory.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85287011","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}

Idea of applying HEN retrofit and fuel switching in existing plant has been proposed to be applied simultaneously in achieving CO2 emissions reduction. Graphical approach combining the mentioned idea has been proposed, but involves potentially time consuming manual procedures. Besides, quality of solution produced greatly depends on designer's experience and judgment, and graphical approach hardly account for the cost factor during the design phase, thus potentially generate complex design. This paper introduces a MINLP model for simultaneous CO2 emissions reduction targeting via fuel switching and HEN retrofit for existing plant. A model execution strategy was proposed along with proposed model.

The resulting model gives an interpretation of the different scenarios that could face real world energy systems. The upper level decision maker, an international body, aims to maximize the total amount of biofuel that is locally produced by each of the lower level decision makers, the countries involved, through setting appropriate adjustments on the international price. On the other hand, each country wants to minimize the cost that they individually incur from the purchase or production of biofuels in meeting their demand, subject to the price adjustments given by the national government. This interaction results in a Stackelberg game. A case study based on the international ethanol trading system is used to demonstrate the model.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88990182","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 proposed system is constructed by a sensor-driven independent conveyance system, which separates one target from the group of them. After the whole surface of the separated target is captured using six cameras, the size, the shape, and the bruise of the target are inspected by using the captured images, respectively. In this paper, the inspection ability of the proposed system is evaluated and analyzed by using red and green bell peppers and yellow paprika.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90870791","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}
