释“成”

许慎认为“成”的本义为“就”。然从“成”字的古文字字形结构、“成”字古义所透露出来的信息及“成”的词义引中线索等方面来考察，“成”的本义当为“城”，即用兵器守卫着的、能容纳民众的聚居地。另外，经过对“成”在其基本义基础上 乳形成的一族同族字的考察，也发现这些同族字的意义都与“城邑”义有关，这又进一步证明“成”之本义非“城邑”义莫属。

Digital Art as Urban Communication

As mobility and migration become the norm,citizens in modern cities live among people who remain strangers to each other.This creates new opportunities and challenges for urban social life.Public space is a critical forum in which strangers encounter each other and have the opportunity to develop social protocols for coexisting in diversity.New media technologies have huge impact on the form and quality of public space.Digital art can create experimental public spaces in which mediated connections and embodied presence are combined in new ways.Through the practice and research of digital art,we can imagine a communicative city in which urban digital media is less about spectacle,and more about promoting new forms of public speech and social encounter between people.

A Preliminary Review on Three-Dimensional City Model

In this paper a review on current research on 3DCM is presented, and an alternative approach by integrating the concepts and techniques of object\|oriented method and Computer Aided Design (CAD) is suggested. Through the approach urban spatial entities as objects are extracted, which are represented with primary 3D elements (node, edge, face and body) and their combinations. In the light of the concept of object, the method supports the multiple representation of Level of Details (LOD). More importantly, topological relationships between objects are described so that 3D topological operations can be implemented.

A NUMERICAL STUDY ON THE INFLUENCES OF URBAN PLANNING AND CONSTRUCTION ON THE SUMMER URBAN HEAT ISLAND IN THE METROPOLIS OF SHENZHEN

By means of the regional boundary layer model (RBLM),a study on the influences of the urban planning and construction on the summer urban heat island (UHI) in the metropolis of Shenzhen is performed.In the study,the current summer UHI distribution,the influences of the increasing high-density construction and the energy consumption on the summer air temperature distribution,and the influences of the urban ventilation corridor on the summer air temperature distribution are numerically analyzed.Some conclusions are drawn in the light of the study:(1) The summer UHI is more obvious in day time than that in night time in the summer of Shenzhen,and the maximum values of UHI intensity in the day time appear in the areas with high-density construction,which are located in Nanshan,Futian and Luohu and western Bao'an districts.(2) The increase of construction density and energy consumption in the urban area will lead to the increase of temperature near the ground,and the increase of temperature at nighttime is more obvious than that at daytime.(3) The ventilation corridor can effectively reduce the UHI intensity and can be taken as a method to eliminate the negative climatic effect caused by the increase of high-density construction and energy consumption in the future.

3D Urban Visualization with LOD Techniques

In 3D urban visualization, large data volumes related to buildings are a major factor that limits the delivery and browsing speed in a web-based computer system. This paper proposes a new approach based on the level of detail （LOD） technique advanced in 3D visualization in computer graphics. The key idea of LOD technique is to generalize details of object surfaces without losing details for delivery and displaying objects. This technique has been successfully used in visualizing one or a few multiple objects in films and other industries. However, applying the technique to 3D urban visualization requires an effective generalization method for urban buildings. Conventional two-dimensional （2D） generalization method at different scales provides a good generalization reference for 3D urban visualization, Yet, it is difficult to determine when and where to retrieve data for displaying buildings. To solve this problem, this paper defines an imaging scale point and image scale region for judging when and where to get the fight data for visualization. The results show that the average response time of view transformations is much decreased.

Base of the Pyramid Population： Identifying Populations to Increase Citizen Participation Through Information Technology

The Municipality of Puebla is today＇s capital of the fourth most important city of Mexico. During 2009, its city hall ranked infirst place in category of metropolitan city as information and communication technologies to reach part of ＂Digital City Award＂. From the strategy to use governmental efficiency, as well as interact with the population and socioeconomic development of the zone, free wireless internet was implemented in 39 areas to facilitate the access to training of citizenship by using this new form of media. The municipality has a population with great economic disparity, which is translated in strong social exclusion, located mainly in housing units and popular colonies with people in situation of hereditary poverty. Because of that, the need of knowing the profile and the consumer habits of mass media communication emerges. The research evaluates identification of actual and potential users of the web2.0, so it can be possible to recognize the chances of intervention in this segment and increase its participation on public character programs and promoting equality of opportunities and the possibility being a participative citizenship that contributes to the local human development.

Personal Urbanities： Domesticating the Public Domain

City and personality have never been easily associated. Historically, since classical antiquity, urban space has always been the reflection of a collective identity representing the natural inclination of human beings to live in group. However, according to Lewis Mumford, the city has been the context in which another ideal arose--the concept of personality. This ideal, according to the official history of urban design, seems to have had a very marginal role, if not as a formal or functional analogous structure. Nevertheless, looking at the physical consistence of built space--as well as its ideal formulation--it is not difficult to find some evidence of Mumford＇s theory. Therefore, the paper, through an architectural overview ranging from classical street-side benches to contemporary digital cities, aims at outlining the progressive change in the representation of urban identities from a collective to a more personal dimension. It describes how public space design, especially during the last 30 years, has redefined its strategies in order to increase the possibilities of personal intervention for users, and it focuses on the gradual shift of this discipline towards other scales, instruments and objectives, in a sudden disciplinary convergence with interior architecture and industrial design. Thus, showing how a pervasive process of domestication is nowadays transforming not only the use, but also the symbolic meaning that the public domain has traditionally had.

Civic Engagement, Fake News and the Path Forward

Media literacy and understanding the digital information around us are an area of communication that affects all of us. How people are represented in the media, social media and our civic participation affect our representations and understanding of the truth. The author would argue through research and practical examples that civic engagement and associations with a peer group can counteract some of the issues facing digital media today. In an age of the so-called ＂fake news,＂ there are tools we can provide for our teams, our employees, and our collaborators to make sure we are all on the same page and dealing with the same set of verifiable facts

Current State of Numerical Simulations and Testing for the Blast and Impact Protection of the Build Civil Engineering Infrastructure

The identification of the critical infrastructure has shown that the build civil engineering infrastructure is almost involved everywhere, even with the IT-infrastructure. Therefore, the passive safety of structures is demanded. Security associations have analysed that most assaults came along with explosion and impact scenarios, which amount in 80% of assaults. Consequently, these are the extraordinary loads the structures have to be planned and designed for. To carry out such an engineering job, the engineer has to be educated in multiple disciplines as physics, material science , continuum mechanics, numerical mechanics, testing, structural engineering and related specific fields as wave propagation etc. In this paper we will concentrate on the subjects of numerical simulation and testing.

Urban Boundary-Layer Stability and Turbulent Exchange during Consecutive Episodes of Particle Air Pollution in Beijing,China

Based on measurements at the Beijing 325-m Meteorological Tower,this study reports an analysis of atmospheric stability conditions and turbulent exchange during consecutive episodes of particle air pollution in Beijing(China),primarily due to haze and dust events(15–30 April 2012).Of particular interest were relevant vertical variations within the lower urban boundary layer(UBL).First,the haze and dust events were characterized by different atmospheric conditions,as quite low wind speed and high humidity are typically observed during haze events.In addition,for the description of stability conditions,the bulk Richardson number(RiB) was calculated for three different height intervals: 8–47,47–140,and 140–280 m.The values of RiB indicated an apparent increase in the occurrence frequency of stably-stratified air layers in the upper height interval—for the 140–280-m height interval,positive values of RiB occurred for about 85% of the time.The downward turbulent exchange of sensible heat was observed at 280 m for the full diurnal cycle,which,by contrast,was rarely seen at 140 m during daytime.These results reinforce the importance of implementing high-resolution UBL profile observations and addressing issues related to stably-stratified flows.

Human Factors in the Analysis of the ＂Tram-Car Drivers＂ at Intersections

The modem tramway has resurfaced as the cure to today＇s urban transport problems such as pollution, road congestion and uneven access to transit. However, trams at intersections often experience frequent and extended delays due to vehicles crossing the tram tracks. There is an increased potential for conflict between trams and vehicles at these locations and crashes are common. The question of the effects of human factors on trams crossroads safety has been little dealt with in literature. The general aim of this article is to further knowledge about the influence of tramway and surrounding environment on car＇s driver behavior at intersections. Understanding these influences, involve conducting a systematic review of the cognitive tasks related to driving and identifying the hazards that can arise at each task, and what factors can make these more or less likely to arise, considering the environmental design at intersections and behavioral factors. To achieve that, the HAZOP （Hazard and Operability Study） approach is conducted for this study. Concerning data collection, the methodology includes site visits to record user behavior and questionnaires to determine the opinion, concerns and knowledge of car drivers in interaction with the tram environment.

Simulation of Land-use Scenarios for Beijing Using CLUE-S and Markov Composite Models

This study investigated and simulated land use patterns in Beijing for the year 2000 and the year 2005 from the actual land use data for the year 1995 and the year 2000,respectively,by combining spatial land allocation simulation using the CLUE-S model,and numerical land demand prediction using the Markov model.The simulations for 2000 and 2005 were confirmed to be generally accurate using Kappa indices.Then the land-use scenarios for Beijing in 2015 were simulated assuming two modes of development:1) urban development following existing trends;and 2) under a strict farmland control.The simulations suggested that under either mode,urbanized areas would expand at the expense of land for other uses.This expansion was predicted to dominate the land-use conversions between 2005 and 2015,and was expected to be accompanied by an extensive loss of farmland.The key susceptible to land-use changes were found to be located at the central urban Beijing and the surrounding regions including Yanqing County,Changping District and Fangshan District.Also,the simulations predicted a considerable expansion of urban/suburban areas in the mountainous regions of Beijing,suggesting a need for priority monitoring and protection.

AN AIR POLLUTION PREDICTION TECHNIQUE FOR URBAN DISTRICTS BASED ON MESO-SCALE NUMERICAL MODEL

Taking Shenzhen city as an example, the statistical and physical relationship between the density of pollutants and various atmospheric parameters are analyzed in detail, and a space-partitioned city air pollution potential prediction scheme is established based on it. The scheme considers quantitatively more than ten factors at the surface and planetary boundary layer (PBL), especially the effects of anisotropy of geographical environment, and treats wind direction as an independent impact factor. While the scheme treats the prediction equation respectively for different pollutants according to their differences in dilute properties, it considers as well the possible differences in dilute properties at different districts of the city under the same atmospheric condition, treating predictions respectively for different districts. Finally, the temporally and spatially high resolution predictions for the atmospheric factors are made with a high resolution numerical model, and further the space-partitioned and time-variational city pollution potential predictions are made. The scheme is objective and quantitative, and with clear physical meaning, so it is suitable to use in making high resolution air pollution predictions.

Groundwater Quality Assessment for an Indian Urban Habitat： A GIS Approach

Groundwater is an essential source of drinking water for many Indian urban habitats. Large numbers of people consume ground water instead of municipal tap water due to contamination of tap water. Groundwater is extracted from thousands of bore wells, and used for potable purpose without proper testing and treatment. This paper describes a groundwater quality monitoring strategy and database model developed for Gulbarga city, located in Karnataka, India. Sampling wells are selected one each in 55 wards of the city corporation having easy access for regular sampling. Various attributes of sampling wells including their spatial coordinates, location address and a photograph are registered for ready recognition on site. Water samples are collected and analyzed for various physico-chemical parameters. Spatial coordinates and levels of sampling points are measured on site using a hand held GPS instrument. Gulbarga city map is digitized. A GIS database of the measured spatial and water quality data is developed using ArcGIS Desktop 9.3, and ground water quality maps are prepared which may serve as useful tools for developing policy, and regulatory mechanism for sustainable groundwater use.

Symmetry distribution of cities in China

The authors of this paper induced five principles of geographical symmetry based on the space distributions of cities and towns in China. There is a symmetry distribution of cities and towns. The symmetry characteristics are the following: (i) the average coordination number of the cities (including large cities, medium cities and county towns) is 6 ( i.g. rotation symmetry); (ii) the distribution of large and medium cities are shown to be the latticework in which two directions are parallel to two main tectonic ones in China, respectively; (iii) the distribution of county towns of a province is also shown to be the latticework in which two directions are parallel to two tectonic ones in this province (i. g. two-dimensional translation ) and (iv) the concentric circle distribution of cities (CCDC) is centered round a large city (i. g. rotation symmetry).
