A control and systems analysis of articial instream aeration,dels relate water quality at specific points on the river and are used in a design study to evaluate the performance of artificial aerators in the River Cam. Operating schemes are developed which utilise closed loop state variable feedback control and feedforward control to maintain adequate levels of dissolved oxygen in the river.

Investigations on Transport Properties of Poly-silicon Nanowire Transistors Featuring Independent Double-Gated Configuration Under Cryogenic Ambient,e conventional theory concerning short channel effects. Through simulation and experimental verification, it was found that such phenomenon is related to a number of structural parameters, and the root cause was identified to be the nonuniformly distributed dopants introduced by ion implantation.

Preliminary investigations include measurements of the steady pressure distribution and flow visualizations at transonic Mach numbers for a fixed mounted wing model with the same airfoil. The experimental results of both, steady and unsteady investigations, se
