There are many methods to create 3D city model, in which the simplest one is to extrude building footprints to obtain “block-shaped” polyhedra representing buildings. While the resulting 3D city models are not topologically consistent, if the 2D topological relationships between the footprints are not taken into account. As a result, the created models only meet the purpose of visualization. In...

One of the simplest methods to construct a 3D city model is to extrude building footprints to obtain “block-shaped” polyhedra representing buildings. While the method is well-known and easy to implement, if the 2D topological relationships between the footprints are not taken into account, the resulting 3D city models will not necessarily be topologically consistent (i.e. primitives shared by 3...

This article revisited past digital cities, and discussed smart cities and the future. If we understand digital cities as exploration of cyber space and smart cities as exploitation of physical space, the next stage is to evolve networked society based on cyber physical systems. The current movements suggest two different directions, socialization of commerce and commercialization of society. W...

Cities present new challenges and needs to satisfy and improve lifestyle for their citizens under the concept “Smart City”. In order to achieve this goal in a global manner, new technologies are required as the robotic one. But Public entities unknown the possibilities offered by this technology to get solutions to their needs. In this paper the development of the Innovative Public Procurement ...

3D city models which represent in 3 dimensions the geometric elements of a city are increasingly used for an intended wide range of applications. Such uses are made possible by using semantically enriched 3D city models and by presenting such enriched 3D city models in a way that allows decision-making processes to be carried out from the best choices among sets of objectives, and across issues...

Smart environments integrate a multitude of different device ensembles and aim to facilitate proactive assistance in multi-display scenarios. However, the integration of existing software, especially visualization systems, to take advantage of these novel capabilities is still a challenging task. In this paper we present a smart view management concept for an integration that combines and displ...

Smart specialization (SS) is a policy concept that has gained significant momentum in Europe despite a frail theoretical background and implementation difficulties. These challenges become critical in the case of less-developed economies that often lack regional autonomy, a strong STI base, and local capabilities to identify and sustain such SS strategies. Combining elements from evolutionary e...

Digital Decor is furniture, appliances, and other small objects commonly found in homes and offices that have been augmented with computational power to extend usefulness. As such, Digital Decor is a physical manifestation of the ubiquitous, pervasive, and invisible computer in which the familiar, everyday object is imbued with additional capabilities through a single, simple application. Thus ...
