This paper investigates the concept of digital city. First, a functional analysis of a digital city is made in the light of the modern study of urbanism; similarities between the virtual and urban constructions are pointed out. Next, a semiotic perspective on the subject matter is elaborated, and a terminological basis is introduced to treat a digital city as a self-organizing meaning-producing...

We simulate the spread of disease within and between the 100 largest metropolitan areas in the United States. Disease is transmitted within cities according to a deterministic compartmental SEIR model (city model). Disease moves stochastically between cities via infected travelers (network model). In each simulation run we alternately simulate a week (i. e., 7 days) of disease transmission with...

Smart cities are high on the political agenda around the globe. However, planning smart cities and deploying applications dealing with the complex problems of the urban environment is a very challenging task that is difficult to be undertaken solely by the cities. We argue that the uptake of smart city strategies is facilitated, first, through the development of smart city application repositor...

This paper provides evidence on the impact of events on the Web reputation of a city. The marketing and tourism literature indicates that events represent an important lever to strengthen the brand of travel destinations. However, the impact of events on the Web reputation of a city is largely unexplored. This paper takes a first step in this direction by measuring the impact of two events on t...

1. We have generated monoclonal antibodies against the SARS coronavirus (SARS-CoV) X1/3a protein (3a), which are suitable for western blotting, immunocytochemistry, and immunohistochemistry. 2. We have established and characterised an in-vivo 3a transgenic Drosophila model, and demonstrated its usefulness in studying SARS-CoV 3a gene function. 3. We validated our in-vivo findings on 3a gene fun...

Spatial orientation is an important ability, which should be facilitated in geometry courses of elementary schools. A preferred approach (in Germany) typically involves navigation and orientation tasks with pictures of a town and city maps depicted in a book. Because of increasing use of computer systems in schools, it is very interesting to explore the value a virtual environment possesses for...

We sketch a workflow for cognitively plausible recognition of vague geographical concepts, such as a city centre. Our approach imitates a pedestrian strolling through the streets, and comparing his/her internal cognitive model of a city centre with the stimulus from the external world to decide whether he/she is in the city centre or outside. The cognitive model of a British city centre is elic...

Planning and construction are well-known practical topics; however, eco-city developments and their sustainable effects on the city are less known. Xi’an is a typical city that has a target to become an eco-city. This city is selected in this case study with the aims of (1) framing eco-practices to enhance the understanding of an eco-city development and (2) evaluating the effect of eco-practic...
