Emissions reduction benefits of adapting electronic closed loop fueling control on a mechanically controlled spark-ignited engine
Recent government gaseous exhaust emissions regulations have been expanded to include a variety of mobile air pollution sources. Exhaust emissions from non-road engines have recently become a focus of Environmental Protection Agency (EPA) regulations. The term "non-road engines" covers many …

Aircraft Detection and Tracking Using UAV-Mounted Vision System
… where non-collaborating flying objects, such as general aviation (GA) aircraft without automatic dependent surveillance-broadcast (ADS-B), exist, the UAVs' capability of “seeing" these objects is especially important. This “seeing", or sensing, can be implemented via various means, such as Radar …

An analysis of current guidance in the certification of airborne software
The use of software in commercial aviation has expanded over the last two decades, moving from commercial passenger transport down into single-engine piston aircraft. The most comprehensive and recent official guidance on software certification guidelines was approved in 1992 as DO-178B, before the …
