at the beginning of this paper, design and manufacturing stages of the 3 degree of freedom test stand for a remotely piloted helicopter is described, in which the helicopter is able to rotate about its three primary accesses. in the next parts the dynamical model of the rph in the yaw channel is presented and lateral transfer function of rph (yaw channel) is extracted by performing several test...

The Institute for Clean Energy Technology (ICET) at Mississippi State University has developed a test stand capable of lifecycle testing of high efficiency particulate air filters and other filters specified in American Society of Mechanical Engineers Code on Nuclear Air and Gas Treatment (AG-1) filters. The test stand is currently equipped to test AG-1 Section FK radial flow filters, and expan...

This study was performed to estimate stand-level volume using the characteristics of vertical and horizontal distribution of airborne Light Detection And Ranging (LiDAR) data. It is found that the height distributional parameters, such as percentile, of LiDAR data reflected onand in-canopy in a stand have the relationship with stand volume in previous research. However, we assumed that the nonp...
