The map of a city’s streets constitutes a particular case of spatial complex network. However a city is not limited to its topology: it is above all a geometrical object whose particularity is to organize into short and long axes called streets. In this article we present and discuss two algorithms aiming at recovering the notion of street from a graph representation of a city. Then we show tha...

urban landscapes form the main parts of the city. one of these spaces is urban streets, in whichsocial interactions and urban vitality reach its maximum quality and quantity. one of the principles and properties ofurban landscape design is its intelligibility. a viewer who takes a look at an intelligible city and knows it can attract newemotional manifestations of city without damaging its orig...

Maintaining human thermal comfort (HTC) is essential for pedestrians because people outside can be more susceptible to heat stress and heat stroke. Modification of street microclimates using tree canopy cover can provide important benefits to pedestrians, but how beneficial and under what circumstances is not clear. On sunny summer days, microclimatic measures were made in residential streets w...

This paper discusses a goal-oriented project called Distance Learning in Multimedia Networks (ETÄKAMU) that was a part of the Finnish Multimedia Programme (FMP). The project started in February 1996 and lasted until January 1999. The project combined the efforts of Finnish telecommunication companies, content providers, publishing houses, hardware companies and educational institutions in the f...

People residing in rural communities are more likely to be physically inactive and subsequently have elevated risks for chronic disease. Recent evidence has shown this could stem from environmental barriers, inadequate programming and policies directed at the promotion of physical activity (PA) in rural settings. The objective of this research was to assess active living features in rural towns...

Child labor is a gradually increasing phenomenon across the world. Children working on the streets are vulnerable to a variety of mental and non-mental illnesses. Due to the scarcity of the research on the health impacts of this phenomenon on these children, this study investigates the risks of mental illnesses and school performance among children working on the streets. A comparative study wa...

In the present article, we introduce a community empowerment perspective to understanding neighborhoods. A preponderance of literature exists on neighborhood risk factors for crime. Yet less is known about positive factors that make neighborhoods safe and desirable. We propose community empowerment as a conceptual foundation for understanding neighborhood factors that promote social processes, ...

Using mathematical simulation, distribution of concentration of harmful substances NOx at Rustavely Avenue, the crossroad of David Agmashenebeli and King Tamar Avenue, where traffic is congested, and for the whole territory adjoined to the crossroad have been studied. In addition, there have been investigated influences of traffic-lights at streets' intersections on the growth of concentration ...

The two-dimensional laminar vortex streets behind a triangle have two morphologically distinct structures depending on the Reynolds number and aspect ratio of triangle. These are conventional structure separated rows structure, where latter is characterized by thin layer irrotational fluid between rows. In this paper, means numerical simulation, we find that occurs when thickness boundary layer...
