The Reaction Products And The Kinetics Of The Reactions Between Hypochlorite Ions And Thiosulfate And Tetrathionate Ions, Thomas Dagon

Theses

The reaction products of the hypochlorite oxidation of both thiosulfate and tetrathionate solutions were determined. In addition, preliminary kinetic studies were made dealing with the alkaline chlorination of thiosulfate solutions and with the hypochlorination of tetrathionate solutions. In the latter case, a pH dependent induction period was observed.

An Active Fet Receiver Front End Mixer, Kenneth Voyce

Theses

In many recent receiver designs, the front-end mixer determines the receiver's sensitivity and its susceptibility to distortion from large input signals. Two balanced FET mixers are developed for such an application; a common source configuration and a common gate configuration. Each exhibits a range of 110 dB between the available input power necessary for 10 dB((S+N))/N sensitivity and the available input power of a two-tone signal which causes intermodulation products down 40 dB from the desired signals. An expression for the conversion transconductance of a junction FET used as a mixer is first derived from the device transfer characteristic equation. …

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 …

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 …

Aerial Oxidation Of Lith Developers, Joe Smith

Theses

Lith developers, unlike conventional developers, lose alkalinity when aerially oxidized. This is attributed to the alkaline reaction of the formaldehyde-bisulfite compound (FBS) commonly employed in lith developers as a "sulfite buffer". Conventional chemical analysis methods are used to obtain data and experimentally derive an equilibrium constant for the alkaline disassociation of FBS. Chemical and sensitometric data are presented that indicate that the alkalinity loss contributes significantly to the overall loss of developer activity. It is also shown that aeriating a lith developer quantitatively converts hydroquinone to hydroquinone monosulfonate that, in turn, is a measurably active developing agent. Additional data are …

Computer Specification Of Centrifugal Pump And Motor, Paul David O'Lenick

Theses

The purpose of this thesis is to develop a PORTRAIT computer program for selecting a centrifugal pump and motor driver. This is accomplished by means of generalized data which establishes the speed of the Dump and its power requirement. After selection of the pump, the motor is sized and specified. In addition to determining the pump and motor, the program also sizes the discharge and suction lines and the required control valve. The resulting solution yields the pump design data, motor, line and control valve sizes. From this data utility and relative equipment costs can be estimated.

The Modulation Transfer Function Of The Human Visual System At Selected Spectral Frequencies, George L. Ayers

Theses

The Modulation Transfer Function of the human visual system has been determined with a sin usoidal test target, by measuring the threshold contrast as a function of spatial frequency, for monochromatic light of constant average luminace. Data were obtained for a broad band range and wavelengths of 538 and 617 nm. It is shown that a maximum MTF occurs at frequencies between 2 0 - 3 0 cycles/mm on the retina and that this sensitivity decreases for both lower and higher frequencies. Small but discrete differences appear in the curves for broad-band radiation and the green and red filtration at …

Polychromatic Mtf Of A Pinhole Camera, Arthur Messenger

Theses

Polychromatic MTFs based on the work of Hopkins and Sayanagi are developed for a pinhole camera using standard 5500°K daylight and a black and white, and a color reversal film. On and off-axis MTF were developed for the radial and tangential cases. Conclusions are drawn about the depth of focus and "best" focal position. A monochromatic depth of field study was done, showing both the need to focus and the infinite character of the pinhole camera.

Noise Power Ratio Testing Of Multichannel Single Sideband Communication Equipment, Per Vinther

Theses

It is shown, that Noise Power Ratio (NPR) testing of multichannel Single Sideband (SSB) transmitters should be performed loading all channels with identical white, gaussian, zero-mean noise signals in order to obtain the worst case result. A theoretical analysis of bichannel equipment under the two different input conditions: (a) statistically independent noise signals, and (b) statistically dependent noise signals; shows that the intermodulation distortion on the output of the transmitter is the same for either case. This result is extended for an arbitrary number of channels to the point of showing that the test results obtained for statistically dependent noise …
