Abstract: A lumped parameter model of the Czochralski crystal growth process is proposed that captures the dominant nonlinear dynamics, internal coupling, and disturbance structure. Conventional and advanced ...

Abstract: An expanded set of control objectives is proposed for the Czochralski crystal growth process. Consideration of the thermal stress near the interface yields an operating regime specification in ...

Abstract: A nonlinear dynamic model of the chemical vapor deposition (CVD) process has been developed to aid design of a closed-loop control system. A lumped control volume analysis is used to capture ...

Abstract: Plasma torches are used in a variety of different applications including forming corrosion and wear resistant coatings, near net shape manufacture, and production of metal matrix composites. The ...
