The analysis of a new viscometer that takes the form of an oscillating plate, fabricated from silicon using the methods of micro-electro-mechanical-systems (MEMS) is considered. The instrument is designed principally for experimental use in the oil industry. The plate is 1.6mm wide, 2.4mm long, and 20μm thick. It is suspended from a 0.4mm thick support by 48 square cross-section legs, each of l...

An experimental investigation has been carried out to determine the applicability of an induction heating process with a travelling induction coil for the rectification of angular welding distortion. The results obtained from experimentation have been used to create artificial neural network models with the ability to predict the welding induced distortion and the distortion rectification achie...

In this paper, the consistent second-order plate theory is developed for transversely isotropic plates. It validated against three-dimensional elasticity using a well-known benchmark problem of simply-supported rectangular subjected to symmetric transverse sinusoidal loading. The choice based on fact that it allows an exact solution be derived in closed form. study, closed-form Elliot’s displac...

Isotropic optical focusing - the focusing of light with axial confinement that matches its lateral confinement, is important for a broad range of applications. Conventionally, such focusing is achieved by overlapping the focused beams from a pair of opposite-facing microscope objective lenses. However the exacting requirements for the alignment of the objective lenses and the method's relative ...
