Places are inherently dynamic. The boundaries of administrative regions (e.g., provinces and countries) and natural regions (e.g., coastlines, ecosystems, mountains, ice sheets, tectonic plates) can alter over time, as can their names. Cities have a daily influx and egress of people and vehicles, buildings go up and down, streets sometimes get repaired, added, etc. Even when a place persists, i...

In today's competitive market, technology transfer is an important problem for firms, organizations and governments. Therefore, making right decisions on selecting a suitable technology and designing an appropriate process to transfer it may have significant influence on the performance of organizations. In this paper, we present a new method to obtain a suitable technology transfer strategy fo...

In this paper we present an algorithm to build a road network map enriched with traffic rules such as one-way streets and forbidden turns, based on the interpretation of already detected and classified traffic signs. Such algorithm helps to automatize the elaboration of maps for commercial navigation systems. Our solution is based on simulating navigation along the road network, determining at ...

The paper presents the results of geographical analysis dendroflora Cheboksary. landscaping system Cheboksary is represented mainly by woody vegetation, which grows in public areas, limited-use plantings, as well along streets and main highways Woody vegetation 73 species, which, according to generally accepted systematics plants, belong 43 genera 20 families. based on archaeological data from ...

Many speed-up techniques developed for accelerating the computation of shortest paths in road networks, like reach or contraction hierarchies, are based on the property that some streets are ’more important’ than others, e.g. on long routes the usage of an interstate is almost inevitable. In grids there is no obvious hierarchy among the edges, especially if the costs are uniform. Nevertheless w...

Pedestrian scenarios refer to all types of transit, including unidirectional, bidirectional, and crossing actions. This study argues that pedestrian are critical normative factors must be considered when implementing street changes in existent residential areas. It focuses on safety reliable access. Making improvements urban streets without adhering the assessment criteria for design results pr...

street dusts are suspended particle matters in the air from different natural and anthropogenic sources that may fall out because of their size and density. forty nine street dust samples were collected from some main streets of eastern and southern parts of tehran. one other sample was also collected from iran university of science and technology central campus for comparisons during summer un...

because of the dispersion of activities in big cities, employing highways as the most important connecting way is indispensable. in today world, highways are connection arteries of cities transporting people to their social activities. because of continual use of highway, their walls prepare a context for conveying many social, cultural, economic, etc concepts. that is why most economic promoti...

Highways are an essential component of our society because they are critical to quality of life and to local and national economies. Under good conditions, highways provide a safe and efficient route for people and goods to reach their destinations. However, as a direct consequence of their use, traffic congestion is ever-increasing, undermining the ability of highways to adequately provide an ...
