RISOptical Parameters in High Efficiency Optical Receivers With a Parabolic Reflector Before and After Coating With Ag Film
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Highefficiency optical receivers before and after the coating of Ag film are composed of a parabolic reflector, a solid parabolic second optical element (SOE), and a Fresnel/aspheric concentrating lens. The optical receivers ...
Fractal Analysis for Vibrational Signals Created in a Ball Screw Machine Operating in Short and Long Range Tribological Tests
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the present study, the vibrational and frictional torque signals acquired from the forwardbackward movements of a commercial ballscrew system were considered via mono fractal analysis. The shortrange tests were carried ...
