World’s first free-flying light sail deployed by US students for sun-powered propulsion
A Cornell student's light sail, which weighs only 0.2 pounds, was released from the International Space Station by astronauts ...
Abstract: This paper presents a reflective-mode planar microwave biosensor based on phase-variation allowing for the detection of low bacteria concentration. The sensor is a one-port coplanar ...
Abstract: In this paper, a displacement sensor based on an open-ended step-impedance transmission line is reported. The sensor operates in reflection, and the output variable is the phase of the ...
Fog sensors and automated fog-detection sensors with electronic message boards warning drivers of low visibility ahead should be set up, and so should reflective road markings and studs, ...
