The convergence of networked digital infrastructures and built environments have given rise to the "urban user", a conflation "the user" resident" or citizen". urban user city are mutually constituted phenomena formed through interactions between them. In this research, we contribute an ethnographic study that focuses on everyday water in Pune, India. Using Nikhil Anand's concept "hydraulic cit...

The rollout of new fixed network infrastructures requires significant capital investments and often a long payback period. To increase the net present value and to limit capital requirements a good rollout strategy is crucial. Cherry picking techniques will select the best areas, based on cost efficiency and highest average return per user, and will only install the new network technology in th...

Cities are places where people, meet, exchange, work, live and interact. They bring people with different interests, experiences and knowledge close together. They are the centres of culture, economic development and social change. They offer many opportunities to innovate with technologies, from the infrastructures that underlie the sewers to computing in the cloud. One of the overarching goal...

For true 3D navigation applications that combine terrain data, city models, landmarks, and other 3D geo data, also a real 3D street network is necessary for the route calculations. In this paper we describe how such a network can be derived automatically using detailed digital terrain models. Furthermore a method is described how the terrain model can be enhanced by integrating the roads direct...

On the trail of Italo Calvino’s Invisible Cities, we must recognize the multi-faceted nature of a given urban space, establish a link between individual practices and the city as a whole, explore the non-hierarchical relationship between ideal and material realities and, finally, shed light on the decisive nature of the city’s selfvisibility. From this perspective, Invisible cities are probably...

The development of case studies in selected Portuguese cities and regions which have been engaged in “digital city” projects is considered in this paper in a way to discuss main challenges and opportunities for mobilizing the information society in Europe, with emphasis for the conditions affecting less favourable zones. It is argued that value-based networks have the potential to make both pub...

Previous terrorist attacks, infrastructure failures and natural disasters have revealed the problems that States face in preparing for civil contingencies. One aspect of this is that the agencies which typically coordinate the protection of critical infrastructures have a national responsibility. However, the impact of particular failures is often focused at a local or regional level. For examp...

Pervasive infrastructures, such as cell phone networks, enable to capture large amounts of human behavioral data but also provide information about the structure of cities and their dynamical properties. In this article, we focus on these last aspects by studying phone data recorded during 55 days in 31 Spanish cities. We first define an urban dilatation index which measures how the average dis...

Water supply access in many developing countries is yet to fulfill Millennium Development Goals. Many local governments are incapable of managing their water resources either due to funding constrains or lack of adequate work force. This often results into poor services with low quality, insufficient and inconsistent delivery of water, leakage and wastage creating water shortages. The water str...
