Environmental change (i.e., urbanization) impacts species in contrasting ways, with some experiencing benefits given their way of life blood-sucking insects). How these respond to such is not well understood and for involved human diseases, this “how” question particularly important. Most Triatominae bug inhabit tropical subtropical forests where vertebrate hosts’ temporal abundance depends on ...

The environment is beyond any form of political, legal and human power. The protection and quality has always been one of the most important components for the improvement and development of life. In 70s began to show the first signs of environmental degradation because of pollution, the allogistis use of natural resources, the resulting energy crisis and the forthcoming population growth on th...

resilience thinking in urban environment has been recently proposed as an effective measure to realize the objectives of sustainable development, minimize uncertainties and non linear interactions. this concept, in the context of modern urban ecology makes it possible to integrate natural and human factors and in urban systems and understanding the interactions between them, expanding sustainab...

This study investigates spatial dependence and mechanisms of regional development in Greater Beijing, China by employing spatial statistical techniques. We have detected positive, strengthening global spatial autocorrelation from 1978 to 2001, and found such strengthening is the result of newly formed/extended clusters in the area. The local analysis recognizes local regimes of two-tier urban-r...

Urban planning is closely related both, to decision making processes as well as to the establishment of a further urban envisioning. Therefore, it is understood as a multidimensional and multipurpose managed change of the natural and built environment. [C.Carmona, 2003] Hence urban planning is a key element for the creation of sustainable cities by its influence on the production of quality spa...

Traffic sign recognition is a difficult task if aim is at detecting and recognizing signs in images captured from unfavorable environments. Complex background, weather, shadow, and other lighting-related problems may make it difficult to detect and recognize signs in the rural as well as the urban areas. Two major problems exist in the whole detection process. Road signs are frequently occluded...

Growing tendency for Urbanization and rapid development of the cities has resulted in urban neighborhoods obstructing the access of each other to the natural sources e.g. solar energy, natural ventilation. Sunlight as the main part of input energy in urban energy balance equation and natural lighting is of vital importance. This paper attempts to achieve an optimum morphology for residential bl...

Considering the problem of automatic traffic signs recognition in natural scene image (mainly including three kinds of traffic signs: yellow warning signs, red prohibition signs and blue mandatory signs), a new method for traffic signs recognition based on central projection transformation is proposed in this paper. In this method, self-adaptive image segmentation is firstly used to extract bin...

The development of urban ecosystems is usually restricted by a few key limiting factors, including both the natural resource condition and the socioeconomic performance. To link the natural, economic and social subsystems together and uniformly measure the multiple ecological flows within and amongst these subsystems, emergy analysis was applied in this paper to describe the status quo of urban...
