Smart City: On Urban Operational Collaboration

This paper expounds the origin of urban operational coordination problem in historical setting, points out that operational coordination problem is essential to cities, induces the major challenges and opportunities for urban operating coordination at present, and takes IBM Intelligent Operation Center as example to illustrate the typical solutions with the detailed case study of the Intelligent Operation Center in Rio de Janerio.

Evolution Process of Urban Spatial Pattern in Hubei Province Based on DMSP/OLS Nighttime Light Data

This paper intends to investigate the urban spatial patterns of Hubei Province and its evolution from three different perspectives: urban nodes, urban connections and urban clusters. The research adopts nighttime light imagery of cities in Hubei Province, the viewpoint of ′point-axis-area′ in the ′point-axis system′ theory, and employs light index model, gravity model and social network analysis. The findings are as follows: 1) In terms of urban nodes, the urbanization process of Hubei has been carried out mainly on the basis of external expansion rather than internal increasing. The polarization trend of urban connection network is strengthening. 2) As for urban connections, the estimation of urban connections using light index model is capable of containing various actual flow, and the connections are getting increasingly closer. 3) In regard to urban groups, seven urban groups of varying sizes have formed. On that basis, three stable and relatively independent urban groups as the centers, namely Wuchang, Yichang and Xiangyang emerge as well. But the structures of ′Wuhan Metropolitan Area′, ′Yichang-Jingzhou-Jingmen City Group′ and ′Xiangyang-Shiyen-Suizhou City Group′, which are defined by local development strategy in Hubei Province, are different from the above three urban groups.

Construction and Upgrade of Urban Power Grids:Achievements and Tasks

The significant achievements in construction and upgrade of China’s urban grids in the past two years and more are enumerated with respect to scale of grids, configuration of medium-and high-voltage grids, technical and localizing level of equipment, as well as social and economic benefits. At the same time, the new tasks for the year 2001 is put forth for volume of investment to be completed, projects progressing and operating benefit indexes, etc.

Consideration on the urban spatial morphology and operation of Taiyuan, China from the religious building perspective

Understanding the physical characteristics and cultural connotations of the historical city is essential for the preservation of their hereditary and cultural values.This work aims to gain a more in-depth understanding of the historical city by identifying the relationship between religious buildings and the urban spatial morphology and the urban operation.Taiyuan,a northern city in China,is a suitable case for exploring this research idea.Cities with frequent foreign exchanges and distinct living groups tend to have more prosperous religious cultures than those in the central areas.The expansion of Taiyuan in the Ming Dynasty and the presence of Prince Jin,who respected Buddhism and Taoism,exacerbated the impact of the religious building on urban development.With regard to the evolution of Taiyuan in the Ming Dynasty,we highlight the changes in urban space brought by the religious buildings through the content analysis of the historical documents.Furthermore,the social functions of religious buildings are revealed,fleshing out the trajectory of the mutual development of religious buildings and Taiyuan in the Ming Dynasty.On this basis,the research findings are linked to the current needs of historical city preservation through the survey of reality.We suggest to coordinate the protection of religious architectural heritage and urban characteristics brought by religious factors and emphasize the utilization of religious architectural heritage as a potential culture and economic regeneration pathway.
