Microstructure Induced Shear Instability Criterion During High-Speed Machining of Ti–6Al–4V
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The microstructure attributes are responsible for the deformation mechanism of material, which induces shear instability primarily in difficult-to-machine material like Ti–6Al–4V. Consequently, the dynamic cutting force ...
Using Horizontal and Slant Lidar Measurements to Obtain Calibrated Aerosol Scattering Coefficients from a Coastal Lidar in Hawaii
Publisher: American Meteorological Society
Abstract: Sea salt aerosol concentrations in the clean marine boundary layer can be considered spatially homogeneous when averaged over space and time. Using this assumption, horizontal and slant lidar measurements are carried out ...
A 50-MHz Logarithmic Amplifier for Use in Lidar Measurements
Publisher: American Meteorological Society
Abstract: A high-speed logarithmic amplifier that has been successfully used to improve the dynamic range of a scanning lidar is described. The amplifier incorporates built-in baseline correction and calibration circuits, allowing ...
