Abstract: With the expansion of pollution-prevention initiatives in the government sector, development of certification and eco-labeling mechanisms in foreign trade, and the emergence of “green” market drivers ...

Abstract: This paper presents an analytical description of the evaporative and fusion laser cutting process. The model incorporates the effects of heat conduction, phase change, beam divergence, surface ...

Abstract: This paper presents a method for reducing the thermal damage of composite materials during laser grooving. The method utilizes a water jet in tandem with the laser beam in an attempt to ...

Abstract: This paper discusses a closed-loop control concept for laser machining. A key development in the proposed control scheme is an acoustic sensor for inferring hole, kerf, and groove geometry in ...

Abstract: This paper presents a concept for performing three-dimensional laser machining on composite materials, using two intersecting laser beams to create grooves on a workpiece. A volume of material ...

Abstract: An acoustic plethysmograph intended to measure the body volume of premature infants has been developed using the principle of the Helmholtz resonator, in which the resonance frequency is dependent ...
