DIRECTION-OF-ARRIVAL ESTIMATION FOR UNMANNED AERIAL VEHICLES AND AIRCRAFT TRANSPONDERS USING A MULTI-MODE MULTI-PORT ANTENNA

Direction-of-Arrival Estimation for Unmanned Aerial Vehicles and Aircraft Transponders Using a Multi-Mode Multi-Port Antenna

Increasing airspace safety is an important challenge, both for unmanned aerial vehicles (UAVs) as well as manned aircraft.Future developments of collision avoidance Dive Mask systems are supposed to utilize information from multiple sensing systems.A compact sensing system could employ a multi-mode multi-port antenna (M 3PA).Their ability to radiat

Lightweight concrete blocks with EVA recycled aggregate: a contribution to the thermal efficiency of building external walls

The regions with lots of shoe production suffer environmental impacts from waste generation during manufacturing of insoles and outsoles.Research conducted in Brazil has demonstrated the technical feasibility to recycle these wastes, especially Ethylene Vinyl Acetate (EVA), as lightweight aggregate, in the production of non-structural cement blocks
