The state of the road surface weather is crucial to road safety， and road icing is one of the main factors causing traffic accidents. To promote the development of road icing recognition and sensing technology， this article reviews the research progress of road icing sensors both domestically and internationally. Firstly， the classification of pavement status was introduced， the hazards of pavement icing to traffic safety were clarified， and the importance of pavement icing identification to traffic safety management was recognized. Then， based on the different ways of pavement icing perception， the pavement icing sensor was divided into contact pavement icing sensor and non-contact pavement icing sensor， and the classification， working principle and characteristics of pavement icing sensor were analyzed and summarized. At the same time， based on the differences of different pavement state recognition technologies and the actual road inspection and monitoring needs， the application scope， recommendation index and improvement suggestions of various pavement icing sensors are given. Finally， the future improvement direction of pavement icing sensor is discussed. It is suggested that the meteorological information system of the road network should be combined with the road icing sensor to realize the timely warning of the road icing state and improve the road traffic safety.

Regional Impact of Cyclone Sidr in Bangladesh: A Multi-Sector Analysis

引用

International Journal of Disaster Risk Science 2016年第3期7卷 312-327页

作者： Afsana Haque Sarwar Jahan department of Urban and Regional planning Bangladesh University of Engineering and Technology(BUET)

This research investigates the impact of cyclone Sidr on six regional economic systems of Bangladesh. The study uses secondary data on direct damages and corresponding changes in consumer spending and public/private investment expenditure. It employs input–output modeling and simulates the changes in national and regional output,income, and employment due to cyclone Sidr. Our findings indicate that coastal regions of Bangladesh—Barisal,Chittagong, and Khulna—are more vulnerable to cyclone disaster than are other parts of the country. The cycloneinduced loss of output is highest for Chittagong Division and income and employment losses are greatest in Barisal Division. The most affected sectors are housing services,agriculture, construction, and industrial activities. But sectoral losses vary widely across the regions. This research also finds that the present state of consumer spending and investment expenditure is not great enough to handle cyclone-induced output, income, and employment losses. It argues that investment decisions must consider regional patterns of output, income, and employment losses in different economic sectors to ensure cyclone-resilient development in Bangladesh.

Absorption characteristics of new solvent based on a blend of AMP and 1,8-diamino-p-menthane for CO_2 absorption

引用

Journal of Environmental Sciences 2012年第5期24卷 897-902页

作者： Sang-Sup Lee Seong-Man Mun Won-Joon Choi Byoung-Moo Min Sang-Won Cho Kwang-Joong Oh department of Environmental Engineering Chungbuk National University department of Environmental Engineering Pusan National University Corporate R&D Institute Fuel Cell System Development Team Doosan Heavy Industries & Construction Greenhouse Gas Research Center Korea Institute of Energy Research department of Energy and Environment Korea Polytechnic VII College

Aqueous 1,8-diamino-p-menthane （KIER-C3） and commercially available amine solutions were tested for CO2 absorption. A 2-amino-2-methyl-1-propanol （AMP） solution with an addition of KIER-C3 showed 9.3% and 31.6% higher absorption rate for CO2 than the AMP solution with an addition of monoethanolamine （MEA） and ammonia （NH3）, respectively. The reaction rate constant for CO2 absorption by the AMP/KIER-C3 solution was determined by the following equation： k2,AMP/C3 = 7.702×106 exp （-2248.03/T）. A CO2 loading ratio of the AMP/KIER-C3 solution was also 2 and 3.4-times higher than that of the AMP/NH3 solution and the AMP/MEA solution, respectively. Based on the experimental results, KIER-C3 may be used as an excellent additive to increase CO2 absorption capability of AMP.

Concept and Method of Asset-Based Community development planning: A Case Study on Minlecun Community in Chongqing's Yuzhong District

引用

China City planning Review 2015年第2期24卷 14-21页

作者： Huang Ling Liu Yang Xu Jianfeng department of Urban planning Key Laboratory of New Technology for Construction of Cities in Mountain AreaChongqing University PENN Institute for Urban Research University of Pennsylvania

With the transformation of the Chinese economy from an extensive growth to intensive development, city development is also gradually turning from incremental construction to stock management. Community, as a basic unit of human settlements, is an important platform to build and improve the social governance capability. In 2013, Shiyoulu Jiedao Offi ce of Yuzhong District led the 1st urban community development planning, which was a milestone of Chongqing's city regeneration and governance innovation. This paper focuses on two key issues: how to understand the community values and make the community development planning based on the above, and how to integrate with the local forces so that the community development planning can be integrated into the action plan. Combined with the practice of Minlecun Community development planning, using the concept of asset-based community development, a comprehensive survey is conducted on community assets(including three aspects of physical, human, and social capital), and a community comprehensive planning strategy is formulated which covers two parts: the optimization of community spaces and the upgrading of community governance. The paper explores the local-based community planning theories and methods from such aspects as value attitude, public participation, role transformation of urban planners, and others.
