Correlation Of 1/F Noise With Threshold Drift In Mosfet's, John Peter Rooney

Theses

A brief review of the fundamentals of MOSFET's is given. A correlation between threshold drift and surface states is made, with a following correlation between surface states and 1/f noise. It therefore follows that MOSFET's with a high 1/f noise level will drift more than those with a low level of 1/f noise. Experiments were carried out to show this effect, but no clear cut conclusions can be drawn from the experimental work.

Financing The Nuclear Fuel Requirements Of Public Utilities, Peter A. Lewis

Theses

A major portion of new electric generating capacity will be nuclear powered. The change to nuclear power will require large outlays of capital not required with conventional fuels to finance nuclear fuel inventories. Nuclear fuel financing requirements are unique because nuclear fuel is not consumed in the same manner as conventional fuels. Financing has not been a problem to date because nuclear fuel can be obtained only through lease from the Atomic Energy Commission. This arrangement will be terminated by June 30, 1973 and from that date on all nuclear fuel must be privately owned. Electric utilities have shown an …

A Rheological Equation Of State For Blood At Low Shear Rates, Anatoly Dritschilo

Theses

In this work a new rheological equation of state is presented and its application to blood is studied. The equation considered is a linear combination of Newtonian and non-Newtonian contributions to the apparent viscosity. The general form of the equation is

T_ij =-(A + Be^{-1/C|(.5)Δi/j:Δj/i|1/2})Δij

Data from the literature were used to test the equation by generating curves of measured torque (T/L) versus applied shear rate (Ω) that would characterize the behavior of blood at all red cell concentrations and all shear rates in the Gilinson, Dauwalter and Merrill viscometer. The constants for the equation were …

Experimental Investigation Of Submerged, Incompressible, Turbulent, Impinging Jets, David Tzeh-Hsian Lee

Theses

Measurements concerning various flow parameters of jets impinging on a smooth lucite plate and a heated metal plate have been carried out. In particular, it is shown that the potential core length of a jet is a function of the Reynolds number and of the jet diameter. It has also been demonstrated that impinging jets behave in many important respects like free jets, except in the immediate vicinity of the target plate.

The flow behavior in the wall jet zone was investigated experimentally, and a satisfactory agreement with the results of the previous investigators was found. The maximum velocity decay …
