Simulation Technology for Advanced Laser Processing Machines

Advanced signal processing methods for pulsed laser vibrometry.

Although pulsed coherent laser radar vibrometry has been introduced as an improvement over its continuous wave (CW) counterpart, it remains very sensitive to decorrelation noises, such as speckle, and other disturbances of its measurement. Taking advantage of more polyvalent polypulse waveforms, we address the issue with advanced signal processing. We have conducted what we believe is the first...

Advanced Treatment of Meat Processing Wastewaters Using Microalgae

Introduction: Effluents of Meat processing are one of the untreated wastewaters containing high volumes of polluted components even after the primary and secondary treatments. The high cost of using the advanced treatment methods of the wastewaters has led the industry owners to release them in the nature without effective removal of nitrogen and phosphorus. In this study, an economic advanced ...

Microstructure and interfaces of a reaction coating on aluminium alloys by laser processing

This paper reports an approach to coat a ceramic layer on aluminium alloys by means of chemical reaction. The reaction product of Al,0, layer of 100 pm in thickness has been formed using a powder mixture of silicon oxide and aluminium by laser processing. It turns out that the large amount of heat from the exothermic reaction has a predominate effects on the formation of the oxide layer. Furthe...
