Digital Elevation Models (DEMs) are 3D representations of the Earth’s surface and have numerous applications in geomorphology, hydrology and ecology.Structure-from-Motion (SfM) photogrammetry using photographs obtained by unmanned aerial vehicles (UAVs) have been increasingly used for obtaining high resolution DEMs.These DEMs are interpolated
This article studies ways of dealing with the tension between a commitment to sustainable and responsible research and anticipated market requirements gary anderson phase 4 in the midstream of a research process in architecture and construction.Using a slightly modified version of Socio-Technical Integration Research (STIR), we explored the chances
The flight mechanical model of tilt-rotor UAV is the basis of designing flight control rate and analyzing flight characteristics.Based on the engineering reality, the nonlinear flight mechanics model of a new configuration tilt-rotor UAV is set up.Features and advantages of the new type rotor-craft are analyzed compared with the traditional ps5 edm
Lumbar interbody fusion (IF) is a common procedure to obtain fusion of the spine by replacement of the intervertebral disc with a cage.Optimization of spinal cages is ongoing to reduce complications such as a pseudoarthrosis and subsidence of the cage.IF animal models (primate, dog, pig, goat and sheep) remain important to assess implant effectivit
