A detailed study of electromagnetic shielding effectiveness (EMSE) of woven fabrics made of polyester and stainless steel/polyester blended conductive yarn was presented in this research work. Fabrics with different structures were analyzed and their shielding behavior was reported under different frequencies. Shielding efficiency of fabric was analyzed by vector network analyzer in the frequency...
An investigation was done on a stainless steel filament and stainless steel/polyester (SS/PET) fibres blended hybrid yarn incorporated conductive fabric to study the significance of SS/PET blended hybrid yarn on electromagnetic shielding when woven with SS filaments. The variations of shielding effectiveness of woven fabric with proportion of SS content, fabric density and weave structure were studied...
Several algorithms have been proposed in the last 25 years on the problem of generating time-optimal trajectories for robot manipulators along specified paths. This article describes an application of an optimal trajectory algorithm to an industrial manipulator used in the transfer of solar panel substrates between process modules. These manipulators operate in a vacuum environment and have constraints...
This paper addresses the effect of substrate temperature and deposition pressure on the electrical properties of Direct Current (DC) plasma magnetron sputter-deposited Tungsten Silicide (WSi) films on silicon substrates. Results from experiments show that, substrate temperature and deposition pressure has exerted significant influence on the electrical properties of the WSi films. The electrical properties...
A multi-resolution wavelet analysis coupled with a neural network based approach is applied in the problem of fault diagnostics of industrial robots. The multi-resolution analysis implements discrete wavelet transforms with filters and decomposes the signal in various levels. The approximate and detailed coefficients of the decomposed signals are then used for training a feedforward neural network...
