The endangered Ethiopian wolf is considered the rarest canid in Africa. The species faces many threats and is particularly vulnerable to diseases such as rabies. A simple, low-technology means to monitor populations would greatly facilitate conservation efforts, through early detection of population changes and behavior, and signaling a need for intervention. We tested a passive tracking index ...

Accurate 3D road information is important for applications such as road maintenance and virtual 3D modeling. Mobile laser scanning (MLS) is an efficient technique for capturing dense point clouds that can be used to construct detailed road models for large areas. This paper presents a method for extracting and delineating roads from large-scale MLS point clouds. The proposed method partitions M...

Today, one of the main applications of multi-source aerial data is the city modelling. The capability to automatically detect objects of interest starting from LiDAR and multi-spectral data is a complex and an open problem. The information obtained can be also used for city planning, change detection, road graph update, land cover/use. In this paper we present an automatic approach to object ex...

Cardiovascular disease (CVD), including heart failure, is a major cause of morbidity and mortality, particularly among African Americans. Exposure to ambient air pollution, such as that produced by vehicular traffic, is believed to be associated with heart failure, possibly by impairing cardiac function. We evaluated the cross-sectional association between residential proximity to major roads, ...

BACKGROUND The 5(th) Iran National Development Plan, 2011-2015, has emphasized on expansion of rural asphalt roads. This article aims to illustrate the trend of deaths caused by rural road traffic crashes (RTCs) and its association with length of the rural roads in Iran. METHODS We carried out a retrospective analysis on secondary data for the period from 2005 to 2010. The Iranian Forensic Me...

An understanding of the ecological effects of roads and related traffic in highly fragmented landscapes is critical because the viability of wildlife that persist through the adverse impact of habitat loss and fragmentation, due to causes such as agriculture or urban land-uses, may be further impaired by the presence of roads. The potential barrier effect can increase the level of population is...

while risk reduction has been mainly addressed by seismologists and engineers by now, the total impact of earthquake greatly depends on urban planning factors. the effects of planning can be considered in the socio economic and physical aspects. urban planning may have a dominant role in various earthquake phases: at the time of earthquake; rescue, and emergency, as well as temporary and perman...
