游走在城市和故土的边缘——评刘国欣的小说集《城客》

《城客》是“80后”学院派女作家刘国欣的小说集,作者从故土乡村经验和现代城市体验出发,揭示出新世纪以来乡下人进城的尴尬与无奈,演绎着一场踯躅于城乡之间的心灵之旅,使“城客”成为一个表征身份的语词,并被赋予精神漂泊的象征意蕴。对城市过客般的疏离感和对故土乡村无望的回眸构成小说的叙述张力,在背叛与逃离中宣示着作者对故土与城市的双重反思;在对爱情飞蛾扑火般的热情中消耗着青春的活力,哀伤与绝望成为爱情体验的情感底色。作者孤绝地游走在城市与故土的边缘,以适合自己的叙事模式和话语方式,完成了对人性的审视和对生存的反思,从而使她的作品带有求新的冲动和不俗的气质。

Control system design of hybrid fuel cell city bus

This paper introduced the design of the hybrid powertrain of the Fuel Cell City Bus demonstrated in 2008 Beijing Olympic Games. The configuration of the hybrid fuel cell powertrain was introduced. The safety of hydrogen storage and delivery system, the hydrogen leakage alarm system were developed. The real-time distributed control and diagnosis system based on the Time Trigger Controller Area Network （TTCAN） with 10 ms basic control period was developed. The concept and implementation of processor （or controller） monitor and process （or task） monitor technique based on the TYCAN were applied in this paper. The fault tolerant control algorithm of the fuel cell engine and the battery man- agement system were considered. The demonstration experience verified that the fault tolerant control was very important for the fuel cell city bus.

Optimization Route Algorithm Based on the Minimal Transfer Time and Distance

The transfer system,an important subsystem in urban citizen passenger transport system,is a guarantee of public transport priority and is crucial in the whole urban passenger transport traffic.What the majority of bus passengers consider is the convenience and comfort of the bus ride,which reduces the transfer time of bus passengers."Transfer time" is considered to be the first factor by the majority of bus passengers who select the routes.In this paper,according to the needs of passengers,optimization algorithm,with the minimal distance being the first goal,namely,the improved Dijkstra algorithm based on the minimal distance,is put forward on the basis of the optimization algorithm with the minimal transfer time being the first goal.

Combination forecast for urban rail transit passenger flow based on fuzzy information granulation and CPSO-LS-SVM

In order to obtain the trend of urban rail transit traffic flow and grasp the fluctuation range of passenger flow better,this paper proposes a combined forecasting model of passenger flow fluctuation range based on fuzzy information granulation and least squares support vector machine(LS-SVM)optimized by chaos particle swarm optimization(CPSO).Due to the nonlinearity and fluctuation of the passenger flow,firstly,fuzzy information granulation is used to extract the valid data from the window according to the requirement.Secondly,CPSO that has strong global search ability is applied to optimize the parameters of the LS-SVM forecasting model.Finally,the combined model is used to forecast the fluctuation range of early peak passenger flow at Tiyu Xilu Station of Guangzhou Metro Line 3 in 2014,and the results are compared and analyzed with other models.Simulation results demonstrate that the combined forecasting model can effectively track the fluctuation of passenger flow,which provides an effective method for predicting the fluctuation range of short-term passenger flow in the future.

Nature Experience, Recreation Activity and Health Benefits of Visitors in Mountain and Urban Forests in Vienna, Zurich and Freiburg

Mountain forests are managed for various purposes. Of these, recreation, leisure, and ecotourism are increasingly gaining prominence. Yet, with the development of new techniques for creating and managing urban forests, the perception of the public with regard to mountain forests and such urban forests is narrowing. For the purpose of this study, eight mountain forests and urban forests located in Zurich(Switzerland), Vienna(Austria) and Freiburg(Germany) were shortlisted. These places are renowned for their well-functioning management of mountain forests and creation of urban forests. As the study was to focus on the comparison of the perceptions of visitors in terms of their satisfaction in urban and mountain forests, the interview covered the following questions:(i) how satisfactory was the nature experience;(ii) how satisfactory were the outdoor recreational activities;(iii) whether the nature experiences influenced the mental and physical health of visitors. Responses thus received for each of the mountain forests and urban forests were assessed, with the total number of respondents being 247. Tourists visiting the selected areas were randomly chosen for a one-on-one interview survey. Results of the survey show that there is a clear perceptions of visitors differed between urban and mountain forests. However, the gap is insignificant or almost nonexistent with respect to satisfaction level of outdoor recreational activities and health benefits. These results are contrary to the findings of previous studies, which argued that the natural landscape of mountain areas is superior to other artificially built green spaces. Visitors did not perceive significant differences in outdoor recreational activities and health effects between the two spaces.

Analysis on inbound tourists' satisfaction in China: an empirical study based on the investigation of 5 cities

In China, the tourism industry is regarded as one means of fostering local economic development. This paper tries to examine inbound tourism development in China in the last decade and analyze inbound tourism's satisfaction of their travel experience with tourist attractions, facilities, services and price by an empirical study based on the investigation of Lanzhou, Wuhan, Guangzhou, Shanghai and Beijing. This paper discusses the demographic characteristics of visitors from Hong Kong, Macao and Taiwan, US, Korea and Japan by surveying a sample of 528 visitors in fi ve different cities. The survey showed that four provinces/autonomous region in western China ranked the top 10 popular destinations. Chinese natural landscape, culture and food were highly regarded by the tourists. At the same time, tourists expressed less satisfaction with tourist language convenience, tourist facility and nightlife in China. It was also found that only 7.4% of the tourists thought travel in China was far more than what they had paid, that 6.5% regarded they got what they paid for, and that 34.9% thought the travel cost was reasonable. Most tourists were satisfi ed with their travel experience in China; many of them would like to return to China and would like to recommend China. For the sustainable development of tourism, Chinese tourism authorities should strengthen the construction, propaganda and management of scenic spots, improve tourist facility and tourist education, especially language convenience, and strengthen the supervision of tickets, souvenir and hotel price.

Study on the Development of Water Transport Network for Passengers in the Gulshan-Banani-HatirJheel Lake of the Capital City of Bangladesh

Dhaka, the capital city of Bangladesh is one of the most overpopulated city in the world and traffic jam is the most severe and regular affliction in the daily life. Also, the existing vehicles are not sufficient in compared to the population of the city. People have to spend many hours simply sitting in the traffic jam. This lessens the productivity of people and brings sufferings to them. Gulshan-Banani-HatirJheel area is the busiest regions within the city and face severe traffic jam during working hours. These lakes are totally unused. Therefore, there is a possibility to build a waterways network for passengers transport through these lakes. This will reduce the affliction of people via reducing traffic jam. The proposed transportation networks will also preserve the natural environment of the lakes and bring a source of entertainment in the city life. Many developed cities in the world like London, New York, Paris, Venice, Shanghai etc. already have implemented waterways network inside the city and successfully made the best use of cistern side.
