2017/6/26
Horizontal alignment and cross section characteristics of a skid trail in a ground-based skidding system including curves, wheel ruts and cross slope can impact on the forest soil. In this study the m...
Evaluating the effects of physiographic parameters on the road cross section in mountain forests (Case study: northern forests of Iran)
hillside slope rock base soil texture
2016/1/29
Road cross section, as one the main effective factors in relation to fill and cut volume, was effective in costs and disturbance of forest road constructions. In this research, the effect of a few phy...

Terrestrial Laser Scanning Technique Cross Section Management System in Tunnel
2015/12/16
Laser scanning technology with high positional accuracy and high density will be widely applied in vast range of fields including
geomatics. Especially, the development of laser scanning technology e...
Many theoretical models of labor market search imply a tight link between worker
flows (hires and separations) and job gains and losses at the employer level. We use rich
establishment-level data to...
