Numerical Integration Of Shell Equations Using The Field Method, Pravin R. Ghael
Numerical Integration Of Shell Equations Using The Field Method, Pravin R. Ghael
Masters Theses
"In this work field equations are introduced to numerically solve the six linear differential equations which determine the displacements and stress resultants for thin elastic shells with axially symmetric loadings. With the applications of the field equations to the analysis of symmetric shells, the two-point boundary-value problem is formulated in terms of twelve first-order ordinary differential equations with boundary conditions at only one point. These equations are solved by using a forth [sic]-order Runge_kutta integration formula. Three problems whose solutions are known have been evaluated to check the accuracy of the field equation method. These are: (1.) Simply-supported, thin circular …
Isotope Effect Of Interstitial Diffusion Of Carbon In A Dilute Fe-Si Alloy, Edward T. Yen
Isotope Effect Of Interstitial Diffusion Of Carbon In A Dilute Fe-Si Alloy, Edward T. Yen
Masters Theses
"The isotope effect of carbon interstitial diffusion in a Fe-2.75at%Si alloy has been measured at -3.10°C using the disaccommodation technique. The disaccommodation has been analyzed in terms of two relaxation processes which are discussed on the basis of the reorientation mechanism of carbon interstitials at Fe-Fe sites and Fe-Si sites respectively. The ratios of the relaxation times [tau]₁₃/[tau]₁₂ are 1.0382 for the former and 1.0072 for the latter relaxation process. This result is discussed on the basis of many-body reaction rate theory"--Abstract, page ii.
Magnetic After-Effects In Dilute Transition Metal Alloys, Robert Henry Graham
Magnetic After-Effects In Dilute Transition Metal Alloys, Robert Henry Graham
Masters Theses
"Temperature dependent after-effects of the initial permeability in ternary dilute ferromagnetic iron-base alloys were studied in the temperature range of -50°C to +30°C. Interstitial carbon and nitrogen were the diffusing elements. Nominal percentages of the substitutional transition elements manganese, chromium, vanadium and titanium were added to determine the extent of substitutional-interstitial pair interactions. No additional temperature dependent after-effect of the initial permeability was noticed in Fe- substitutional -C alloys, while such after-effects were present in Fe- substitutional -N alloys. Magnetic after-effect data were analyzed on the basis of single Debye relaxations. Relaxation times for carbon and nitrogen diffusion in alpha-iron …

The Design Of A Molten Fueled, Vortex Reactor, For Use As A Rocket Propulsion Device, Robert Philip Schmitt
The Design Of A Molten Fueled, Vortex Reactor, For Use As A Rocket Propulsion Device, Robert Philip Schmitt
Masters Theses
"The purpose of this investigation is to design a nuclear reactor which can be used as a rocket propulsion device. The reactor investigated is fueled with a molten uranium-bismuth alloy and utilizes a two phase vortex flow principle. Hydrogen is employed as a coolant and rocket propellant. The hydrogen is heated directly by the fuel thus eliminating the need for heat exchangers. The major part of the investigation consists of a two group neutron diffusion study to show the operational feasibility of this type of reactor and to obtain an optimum design. the study shows that this type of reactor …
Semiempirical Determination Of The Differential Fast Flux Spectrum For U-235 Fission With Water Moderator, Henry Anthony Till
Semiempirical Determination Of The Differential Fast Flux Spectrum For U-235 Fission With Water Moderator, Henry Anthony Till
Masters Theses
"The differential fast flux spectrum of the UMR Pool Research and Training Reactor core was determined by simultaneous activations of threshold foil detectors by neutron-nucleon reactions. This represents one phase of the composite neutron environment at two sample irradiation locations and the center of a fuel element during a power operation of 200 Kw (th). To accomplish this measurement a semiempirical least-squares approximation fitting activation date to a theoretical Cranberg U-wet fission spectrum was applied. This is a technique designed specifically for water moderated systems and takes into consideration both virgin and down-scatter neutrons. Gamma decay photopeaks were reduced using …
A Study Of Solvent Effects On The Reaction Between P-Nitrobenzyl Chloride And Hydroxide Ion In Aqueous Dioxane Homogeneous Media, Ken K. Ho
Masters Theses
"The kinetics and activation parameters of the reaction between p̲, p̲' - dinitrostilbene quantitatively, have been studied in five aqueous dioxane solvent systems at five different temperatures between 20⁰ and 40⁰C. At any one temperature the second-order rate constants are minimum in the 30% dioxane solvent mixture, reach a maximum in the 50% dioxane systems, and fall off slightly in the 60% and 70% dioxane systems. The Arrhenius activation energies are highest in the 30% dioxane and lowest in the 70% dioxane systems. The free energies of activation change in the same direction but the magnitude of change is much …
Transient Response Of A Class Of Distributed Systems, Jaw-Shyong Tzeng
Transient Response Of A Class Of Distributed Systems, Jaw-Shyong Tzeng
Masters Theses
"The transient response of uniform distributed systems with any transfer function that is rational in w=e[square root of Ts] can be analyzed with the basic form of the transfer function [1 over (w-a)] after partial fraction expansion, where the pole a can be real or complex in the w plane. with the complex pole within the stable region in the w plane, there are only two possible combinations of the basic transfer function [1 over (w-a)], i.e. [1 over (w-a)] ł [1 over (w-a*)], for physical realizability. The imaginary part of the transient response of the basic transfer function [1 …
Film Boiling Of Nitrogen From A Spherical Heating Surface At Atmospheric Pressure And Standard Gravity, Juan Jorge MariáNyi
Film Boiling Of Nitrogen From A Spherical Heating Surface At Atmospheric Pressure And Standard Gravity, Juan Jorge MariáNyi
Masters Theses
"A steady state film boiling heat transfer study was conducted at atmospheric pressure, with a heated sphere as the heat transfer surface and liquid nitrogen as the boiling medium. Results indicate that the heat transfer rate in film boiling is not the same around the sphere. For the same heat flux, heat transfer at the sides of the sphere takes place at higher temperatures than at the bottom of the sphere. The data were compared with the equation of Frederking and Clark for spheres (1̲8̲), which was derived to predict steady state conditions at standard, fractional and near zero gravity. …
The Compressibility Of Preconsolidated Till, William H. Koechlein
The Compressibility Of Preconsolidated Till, William H. Koechlein
Masters Theses
"Preconsolidated glacial till was tested "in-situ" with the Geoprobe and in the laboratory on undisturbed soil samples. The two soil testing methods were compared and three tests; consolidation, "thin-cake", and Geoprobe were analyzed to see if a more rapid method for determining the preconsolidation stress of soil could be developed. When comparing Geoprobe results to laboratory results for foundation conditions, it was found the two methods agreed on bearing capacity but differed significantly on settlement. The three tests analyzed for determining the preconsolidation stress indicated they are a function of preconsolidation stress even though there was variation in the test …
A Fluidic Liquid Level Control System, Vinod Kumar Verma
A Fluidic Liquid Level Control System, Vinod Kumar Verma
Masters Theses
"The prime objective of this investigation was to design and construct a working "Fluidic liquid level control system", and to make a functional study of the characteristics of the devices employed therein. A working model of a "fluidic liquid level control system" is developed and experimental data is collected to describe the functional characteristics of the fluidic circuits employed. The system contains a pressure sensitive, variable frequency oscillator; appropriate demodulation stages to convert the variable frequency alternating signal into a varying non-alternating signal; and on-off control elements in the final stages"--Abstract, page ii.
The Computer-Aided Generation Of Flow-Tables For Asynchronous Sequential Circuits, Ronald Lee Altman
The Computer-Aided Generation Of Flow-Tables For Asynchronous Sequential Circuits, Ronald Lee Altman
Masters Theses
"One step in the synthesis of asynchronous sequential circuits is the construction of a flow table. This paper discusses the requirements of a computer program to allow on-line generation of flow tables for asynchronous sequential circuits. Such topics as the form of the data entered into the program, the type of terminal required, the routines necessary for the designer to enter and correct data, and the internal data structure are discussed. An algorithm for the generation of these flow tables is also presented"--Abstract, page ii.

A Study Of A Model-Referenced Adaptive Control System, James William Graham
A Study Of A Model-Referenced Adaptive Control System, James William Graham
Masters Theses
"A model-referenced adaptive controller for a first-order plant with time-varying parameters is developed using Lyapunov's second method. The system is studied with the aid of analogue computer simulation and an oscillatory mode is encountered. A method of reducing the oscillations by addition of a compensating network is proposed. The compensation is obtained through the use of linearization and root locus techniques. The compensated system shows a much improved error response over the original system"--Abstract, page ii.
A Mechanical Metallurgical Method Of Predicting The Springback Tendencies Of A Bent Metal Strip, Jerrold Myles Alyea
A Mechanical Metallurgical Method Of Predicting The Springback Tendencies Of A Bent Metal Strip, Jerrold Myles Alyea
Masters Theses
"Attempted substitution of new solid materials and composite metal strips for those materials presently being used in many applications now being pursued vigorously in industry. A serious problem was created because the newly proposed materials do not exhibit the same springback after bending as did the previously used materials in a particular bend angle and radius situation. Elementary bend theory and mechanical metallurgical techniques have been incorporated into a method which can be used to accurately predict the .2% offset yield strength of any proposed rolled-temper solid metal strip and some composite strips when they must exhibit the same springback …
A Method Of Supervised Pattern Recognition By An Adaptive Hypersphere Decision Threshold, Darroll Steven Mccormack
A Method Of Supervised Pattern Recognition By An Adaptive Hypersphere Decision Threshold, Darroll Steven Mccormack
Masters Theses
"In this study the Bayes likelihood detector is combined with an adaptive decision threshold classifier to solve the multicategory pattern recognition problem. It is assumed that the pattern classes can be represented by an n-dimensional vector sample taken from a multivariate gaussian probability distribution. This study presents (1) the derivation of the A̲daptive H̲ypersphere D̲ecision T̲hreshold classifier (AHDT classifier) and shows (2) how the AHDT classifier minimizes the probability of error using the learning patterns. Finally the AHDT classifier is applied to the solution of a physical problem through computer simulation"--Abstract, page ii.
