Introduction: Choosing a theme for a conference especially one for a group of diverse disciplines such as the American Water Resources Association encompasses, is always a challenge. you find yourself torn between thigns you'd really like to talk and hear about, and topics you think will draw attendance. It was most fortunate when somebody came up with the idea of Water for Energy, becasue to my way of thinking, it met both of these ends. There is no denying that starting in late 1973, energy has been the catchword, and the energy crisis has been the bandwagon to leap upon. …

Generalized Likelihood Signal Resolution, John A. Stuller
Generalized Likelihood Signal Resolution, John A. Stuller
Electrical and Computer Engineering Faculty Research & Creative Works
This Paper Defines an M-Ary Generalized Likelihood Ratio Test (MGLRT) that overcomes Root's Early Objection to the Application of Generalized Likelihood Ratio Testing to the Resolution of Correlated Signals. the Proposed Test Extends the Form of a Conventional Binary Generalized Likelihood Ratio Test (GLRT) in a Manner that Permits a Generalization of the Minimax Properties of the Binary Test to the M-Hypotheses Case. When the Estimated Signals Are Orthogonal, the Test Reduces to a Sequence of Conventional Binary Tests Duplicating the Performance of a Narrow-Band Matched Filter Envelope-Detector Receiver. © 1975, IEEE.

A Strategic Planning Model For Implementing Community Development Block Grant Programs., John M. Lang
Masters Theses
"As problems of metropolitan areas have multiplied, the federal government has been drawn into an ever-increasing intimate funding association with city governments. Although federal funding for ii urban problems may have been considered a panacea by some, most local government agencies have now discovered that their problem has shifted in emphasis from where to find funds to that of meeting federal standards and requirements of application in order to get the funds.
The impact of federal programs on local government management is evident in the recently enacted federal Housing and Community Development Act of 1974. Title I of the act …
The Influence Of Oxygen Activity On Sintering Of Strontium Doped Lanthanum Chromite., Leslie Groupp
The Influence Of Oxygen Activity On Sintering Of Strontium Doped Lanthanum Chromite., Leslie Groupp
Masters Theses
"The influence of oxygen activity upon the sintering of lanthanum chromite (La1-xSrx CrO3) with x ranging from Oto 0.2 was investigated using chemically prepared powders of <0.1 microns particle size. The results show that at a temperature of 1740 ° C densities of >92% of theoretical could be achieved if the oxygen activities were maintained in the 10-11 to 10-12 atm. range. If oxygen activity exceeds 10-10 atm., densities of not >80% theoretical could be obtained. For the compositions studied, room temperature X-ray analysis of both the starting powders and sintered compacts show the compositions to be orthorhombic and single phase. The ambient lattice parameters and resistivity measurements decreased …0.1>

An Experimental Study Of Mass Transfer To Droplets In Aqueous Polymer Solutions., Richard Gerard Schafermeyer
Masters Theses
"Instantaneous and time-average mass transfer coefficients for 1 the free-fall period was obtained for transfer of iodine from nonNewtonian continuous phases to carbon tetrachloride drops. The nonNewtonian continuous phases were aqueous solutions of carboxymethyl cellulose and carboxy polymethylene. Although a few exceptions were found, the continuous phase mass transfer coefficients were, in general, found to decrease with increasing time of drop contact. Comparisons of the experimental data to theoretical relations showed that changes in drop internal circulation probably occurred for that data which showed a time effect for the mass transfer coefficient. Several explanations for the time effect were offered, …

Computer Simulation Of Radiation Effects In Fe₃Al By Using Alternating Direction Implicit Numerical Techniques., Dean Lewis Tibbitts
Masters Theses
"An analysis was conducted to see if the alternating direction implicit (a.d.i.) numerical technique could be applied to a many-body dynamical radiation damage model.
The computer program which resulted was named ADI. It was numerically stable for small time steps used in conjunction with low ev knock-ens. It was also able to relax the a toms in the system simultaneously in the implicit direction. However, an existing explicit computer code, which was to be replaced by ADI, proved to be more numerically stable and about 40% faster"-- Abstract, p. ii

A Study Of Product Inhibition In The Reaction Of P-Nitrophenyl- Α - D - Glucoside Catalyzed By The Enzyme Glucoamylase I., Mark L. Dickhaus
Masters Theses
"The entire time course of the hydrolysis of p-nitrophenyl-a-D-glucoside by the enzyme glucoamylase I was followed spectrophotometrically. Using time versus absorbance data the constants in the Michaelis-Menten equation were determined. The effect of the addition of product to the initial reaction mixture and the effect of solvent and temperature were determined. It was found that product produced during the reaction did not have the same effect upon the rate as did product added initially to the reaction mixture. The presence of substrate caused the enzyme to acquire protection against inhibition by the product"-- Abstract, p. ii

Performance Evaluation Of Linear Systems Using The Fast Fourier Transform., Larry Leonard Lamano
Masters Theses
"In order for a computer simulation of a communication system to yield useful and meaningful results, a method for determining system performance is often essential. The computer postprocessor, described in this thesis, allows accurate determination of the mean-square-error induced by the system being simulated and the noise power at any point in the system.
Measurements of the mean-square-error induced by a system due to amplitude distortion, phase distortion, and amplitude and phase distortion, along with measurements of the power in a Gaussian noise waveform are performed. The values obtained using simulation are compared to the corresponding theoretical values in order …

Image Detection In Signal Dependent Noise., Robert D. Laramore
Image Detection In Signal Dependent Noise., Robert D. Laramore
Masters Theses
"This thesis deals with the detection of two-dimensional signals in the presence of noise, including signal dependent noise. The object to be detected and the background are assumed known a priori. A decision rule based on a likelihood ratio test is obtained and the associated probabilities of detection and false alarm are evaluated. This is done first in general terms, where neither the form of sampling nor the model used for noise is specified. Then results are obtained for three examples: Poisson noise, signal dependent Gaussian noise, and binomial noise. Finally, the degradation resulting from a point spread function is …
The Spheriodization Of Tool Steels., Siri Ram Rai
The Spheriodization Of Tool Steels., Siri Ram Rai
Masters Theses
"Four different tool steels--AISI 01, Sl, A9 and Tl5--were obtained in the 1/2-inch diameter hot rolled and air-cooled condition from the steel mill. The lower critical temperatures of these steels were determined. The spheroidization of each steel by three different spheroidizing procedures was evaluated with the use of hardness testing and metallographic techniques. Isothermal annealing completely spheroidized each steel yielding coarse carbides and low hardness. Cyclic annealing was an effective spheroidization procedure only for 01 and Tl5 steels. Hardening and tempering resulted in rather fine spheroidized structures in these steels. The total time consumed to produce the best spheroidized structures …

Ultrasonic Instrumentation And The Dynamic Evaluation Of Asphalt-Aggregate Mixtures., John Edward Hill
Masters Theses
"Ultrasonic probes have been constructed for use in the dynamic and nondestructive testing of asphaltic concrete specimens. The probe systems exhibited characteristics superior to the solitary ii use of their main components, the piezoelectric crystals. The probes have the advantages of the reduction of ringing time, the concentration of ultrasound in one direction, the elimination of "noise" due to unshielded connections and the increased durability of the probe system.
The probes constructed were used in a limited testing program. Compression and transverse wave velocities in the specimens tested were measured simultaneously. Sample conditions suitable for maximum wave velocity corresponded to …
