Global Medical Device Nomenclature ( GMDN) is a system of internationally agreed generic descriptors used to identify all medical device products. This nomenclature is a naming system for products which include those used for the diagnosis, prevention, monitoring, treatment or alleviation of disease or injury in humans.
Look-down/shoot-down radars have been enhanced with electronic programs that process the radar image and search for moving objects, which are detected by looking for Doppler shifts in the radar return. See moving target indication. The radar removes all stationary objects (e.g. the ground and buildings) from the display and shows only moving ...
Introduction: Ray tracing and rasterization. The problem of rendering 3D graphics can be conceptually presented as finding all intersections between a set of "primitives" (typically triangles or polygons) and a set of "rays" (typically one or more per pixel).
