Adding new corridors to a highway network represents a multicriteria decision process in which a variety of social, environmental and economic factors must be evaluated and weighted for a large number of corridor alternatives. This paper proposes a new bi-level continuous location model for expansion of a highway network by adding several highway corridors within a geographical region. The uppe...

This article presents a new algorithm to recognize natural distinctive places such as corridors, halls, narrowings, corridors with open doors on the left side etc., from indoor environments using Hidden Markov Models. The environment is modelled as a graph. This graph is obtained from a Voronoi Diagram from measurements of laser scanner. The characteristics of Voronoi Diagram (nodes, number of ...

Conserving migratory ungulates in increasingly human-dominated landscapes presents a difficult challenge to land managers and conservation practitioners. Nevertheless, ungulates may receive ancillary benefits from conservation actions designed to protect species of greater conservation priority where their ranges are sympatric. Greater Sage-Grouse (Centrocerus urophasianus), for example, have b...

Natural resources are the material basis of urban construction, as well a crucial factor that determines livability and employment opportunities given city. Under traditional development model, cities rely on their natural to develop regional economy. However, this is always accompanied by environmental impacts. Maintaining optimizing ecological environment such during economic not only related...

The massive growth of some urban areas has led to new constellations of urban forms. New concepts describing large urban areas have been introduced but are not always defined and mapped sufficiently and consistently. This article describes urban corridors as an example of such a concept with an ambiguous spatial definition. Based on the existing usage of the concept in scientific literature and...

Mobile robots operating in dynamic ooce environments need robust navigation algorithms capable of dealing with uncertainties arising from sensor and actuator errors. Such algorithms also need to be able to synthesize plans that take into account temporal aspects of their environment, such as crowded corridors, and busy intersections. This paper describes a novel mobile robot navigation architec...


 The article analyzes the current situation and dynamics of ecotourism in Azerbaijan, role national parks development this sector, possibilities using natural cultural heritage resources for ecotourism. growing demand on international tourism market is based joint use existing potential heritage, which implies its implementation liberated territories. shows importance products offered by ...

The rapid development of urbanization has caused many ecological issues and greatly threatened the sustainable human society. construction security patterns (ESPs) offers an effective way to balance conservation urbanization. This study aimed take highly urbanized city Shenzhen, China, as a area construct urban ESP put forward suggestions for security. Ecological sources were identified through...

Overwhelming evidence points to the importance of maintaining connectivity given rapidly fragmenting habitats and climate change. Many efforts identify where ecological corridors should be placed are based on estimates structural that take advantage readily available land-cover data. We provide an overview methodology review various limitations these methods for functional -- degree which facil...

Fragmentation and reduced continuity of habitat patches threaten the environment and biodiversity. Recently, ecological networks are increasingly attracting the attention of researchers as they provide fundamental frameworks for environmental protection. This study suggests a set of procedures to construct an ecological network. First, we proposed a method to construct a landscape resistance su...
