This work proposes a mathematical model to optimize bus service by minimizing total cost and considering a temporally and directionally variable demand. An integrated bus service, consisting of all-stop and stop-skipping services is proposed and optimized subject to directional frequency conservation, capacity and operable fleet size constraints. Since the research problem is a combinatorial optimization problem, a genetic algorithm is developed to search for the optimal result in a large solution space. The model was successfully implemented on a bus transit route in the City of Chengdu, China, and the optimal solution was proved to be better than the original operation in terms of total cost. The sensitivity of model parameters to some key attributes/variables is analyzed and discussed to explore further the potential of accruing additional benefits or avoiding some of the drawbacks of stop-skipping services.展开更多

He cannot find identification with himself in the hostile city which does not provide any chance for him to be a better man. What is more, the absence of community in the city makes his strife become hopeless, and drives him into the state of alienation. Opposing against the brutal surroundings, he turns to violent behavior for the spiritual rescue. Yet, since violence derives from a sense of impotence, it cannot protect him from being alienated. Bom in a lower class, however hard he tries, Jules becomes powerless in front of the relentless society and doomed to be a tragedy展开更多

In late of 2000, for most of the perspectives about Korean waves had been moved on the 3rd stage of the K-pop industrial structure, K-pop idol stars as contents of Korean popular music have turned the pivotal co.ntents in East Asia and West countries. This research examined how Taiwan Residents K-pop consumers are identified as the K-pop enthusiast legitimizing and what they represent the "prosumer" of Korean popular music. Moreover, the practice of K-pop is getting turn consumer in Korean song karaoke (KTV) in Taipei city. What sort of cultural form emerges the political representation in the cultural space, K-pop KTV in Taipei. Through how Taiwan Residents K-pop followers diverse K-pop music for singing K-pop in KTV, it could more elaborate the meaning of contents the culture form of space between production and consumption of the cultural mediation.展开更多

Through human experience of urban public space, the design of public space in the city questioned the rationality, emphasized the human behavior activities on public space design requirements, and emphasized the place of people, human behavior activities, and the activities of the Trinity design ideas. By comparing the two public spaces Analysis of Chongqing, it further emphasized the left of human activity, human stories and spirit; public space has lost its significance.展开更多

Brazil has a high eolic potential, where the annual mean wind speed may reach over eight meters per second. This case study is aimed to assess the economic feasibility of the installation of small wind power plants in urban areas. This work evaluates a project for the installation of a vertical axis wind turbine in three buildings (15-, 22-, and 26-story) including the following stages: (1) installation of a real-time power meter in the 15-store unit; (2) demand analysis of the 26-store building's power consumption; (3) winds survey along the coast of the State of Ceara; (4) analysis of the wind turbines available in the market; (5) simulation aimed to choose the system. Vertical wind power generators offer better conditions of use in urban areas. The turnover time was established to be between four and six years in the three studied units. The installation of a wind power generator on buildings in regions with an adequate eolic regimen reaches a financial return of the investment before the end of the equipment's lifespan.展开更多
