Experimental Investigation of Factors Influencing reworks in Construction

Semi-Automated As-Built Modeling of Light Rail System Guide Beams

For a light rail system, smooth contact between the vehicle and the guide beam is critical for reducing the friction and the vibration of an operating vehicle. Therefore, the shape of guide beams needs to be controlled with mm-level accuracy during the construction. Currently, most methods for detecting shape defects of guide beams, such as experimental run of vehicles, are costly and tedious. ...

Experimental Investigation on the Effect of Parameters Influencing the Performance of a Horizontal Styrene-Water Separator

Sunlight effect on Ca and P serum concentration and factors influencing on regulation of two lons

The sunlight has an important role in metabolism of calcium ( Ca) and phosphorus ( P). The sunlight has different effects in different places. Therefore  the pattern of metabolic disease depends upon geographical place. In this investigation two groups of workers( one group working in shadow and the other under the sunshine) were chosen as control and experimental groups respectively.these two ...
