We customize a transversely structured, tunable light landscape on the basis of orbital angular momentum (OAM)-carrying beams for purpose advanced optical manipulation. Combining Laguerre-Gaussian (LG) modes with helical phase fronts opposite OAM handedness, counter-rotating transfer is enabled in concentric intensity structure, creating dynamic "grinding" scenario dielectric microparticles. de...

Abstract: In this paper a reduced structure multivariable controller is developed for the model of a closed-system grinding circuit. The said controller is developed using a novel technique which employs basis pursuit regularization in order to generate a family of solutions which together span the entire range from decentralized to centralized controllers. Using this information, and the perfo...

Injuries resulting from the use of angle grinders are numerous. The most common sites injured are the head and face. The high speed disc of angle grinders does not respect anatomical boundaries or structures and thus the injuries produced can be disfiguring, permanently disabling or even fatal. However, aesthetically pleasing results can be achieved with thorough debridement, resection of wound...

Understanding the energy requirement for biomass size reduction would be very significant for the process of converting the biomass to bioenergy. A hammermill was used for size reduction operations. One 12.7 mm size screen was applied to hammer mill for different particle size reduction. Torque Sensor was connected to the engine shaft to measure the transfer of torque and engine rotational spee...
