Home range and diet of stoats inhabiting beech forest were examined by trapping and radiotracking. Eleven stoats (6 female, 5 male) were fitted with radio-transmitters. Minimum home ranges of five females averaged 124 ± 21 ha and of four males 206 ± 73 ha. Range lengths of females averaged 2.3 ± 0.3 km and of males 4.0 ± 0.9 km. These differences were not statistically significant. Adult female...

finding a minimum allowable radius length of a circle horizontal curve is essential to reduce earthwork cost or damage to the forest ecosystem, as well as make driving more comfortable. the present study is conducted i) to analyze different radius lengths of circle horizontal curves using an integrated approach consists of a civil3d in concert with the field surveys, and ii) to propose a set of...

Today, during the life of an open pit mine, million tons of materials, including waste and ore, are displacing by truck fleets. In the case of a shallow ore deposit, which is located up to 300 meters to the ground surface, depending on preliminary equipment size and capacity, it will take three to five years to remove overburden and waste rocks to expose the ore body. In that period, the main w...

Road traffic congestion in modern cities has become essential problem which need to be solved. To solve this problem, we have proposed a dynamic traffic light controller system based on image processing. Images (the road-images) used in this research are taken by digital camera placed at fixed position in the traffic-light with specific resolution and distance. The taken images will be analyzed...

background: since most clinical treatments of persian children’s language impairments are based on either the therapist, clinicians’ experiences (mostly), or english language norms (sometimes), comparing two minor indices of speech quality, namely “mean length of utterance” (mlu) and “mean length of five phrasal utterances” (mlfpu) between different age groups of children, would be unequivocall...

We consider the decentralized scheduling of a large number of urban traffic lights. We investigate factors determining system performance, in particular, the length of the traffic light cycle and the proportion of green time allocated to each junction. We study the effect of the length of the traffic cycle on the stability region a urban traffic network. We derive a simple square-root cycle len...

BACKGROUND Physical activity is an important determinant of health. Walking is the most common physical activity performed by adults and the presence of sidewalks along roads is a determinant of walking. Geographic information systems (GIS) can be used to measure sidewalks; however, GIS sidewalk data are difficult to access. The purpose of this study was to present a new GIS method for measurin...

Moving car on rough road suddenly gets out of its way for some reason and moves to the edge of the road at the same speed. Since the most important factor in car overturning is vertical acceleration in the wheels and car speed and road conditions determine the vertical instantaneous acceleration, brake system according to change of the spring length is designed in such a way that by monitoring ...

introduction: disabled-adjusted life year (daly) makes it possible to calculate the time and duration of the disease and its non-fatal consequences along with the time lost due to premature death. this study was aimed to estimate the burden of road traffic accidents (rta) in kermanshah province. methods: to determine the mortality related to road-traffic accidents as well as years of life lost ...
