A free-space microwave nondestructive testing and evaluation module is developed for the low-power, non-ionizing, contactless, real-time characterization of doped composite thin-film materials in an industrial context. The instrumentation proposed built up with a handled vector network analyzer interfaced corrugated horn antennas to measure near-field complex reflection S11 planar prepreg roll-...

This paper presents the development and simulation results of a computer simulation software for the lateral position control of a moving web in roll-to-roll (R2R) systems. Mathematical models of the web dynamics are described first to explain the lateral motion of a moving web. Based on the models, a controller that employs the PID control method is developed, and embedded in simulation softwa...

the effect of pre-existing nano sized precipitates on the mechanisms and rate of grain refinement has been investigated during the severe plastic deformation. a binary al–0.2sc alloy, containing coherent al3sc particles, of 3.62 nm in diameter has been deformed by accumulative roll bonding up to 10 cycles. the resulting deformed structures were quantitatively analyzed using electron backscatter...
