Effect Of Precursor Heating On Radiating And Chemically Reacting Viscous Flow Around A Jovian Entry Body, Kuo Yen Szema

Mechanical & Aerospace Engineering Theses & Dissertations

The influence of changes in the precursor region flow properties (resulting from absorption of the radiation from the shock layer) on the entire shock layer flow phenomena around a Jovian entry body is investigated under physically realistic conditions. In the precursor region, the flow is considered to be inviscid and the variations in flow properties are determined by employing the small perturbation technique as well as the thin layer approximation. The flow in the shock layer is assumed to be steady, axisymmetric and viscous. The analysis is carried out by considering both the chemical equilibrium and nonequilibrium composition of the …

Analysis Of Moisture Absorption And Diffusion In Fiber Reinforced Polymeric Resin-Matrix Composite Materials, Stephen Stern Tompkins

Mechanical & Aerospace Engineering Theses & Dissertations

The diffusion of moisture through fiber reinforced polymeric-matrix composite materials has been studied analytically. The diffusion in the orthotropic, nonhomogeneous material was modeled, in detail, with a two-dimensional transient diffusion analysis. An effective diffusivity for the composite was determined in terms of the fiber volume fraction and the resin diffusivity. This effective diffusivity is in better agreement with recent data than those previously determined using less complex models.

The influence of both material and environmental parameters on the moisture content of the composite was determined analytically. Predicted moisture contents were compared over a wide range of values for emittance, solar …

The American Family In A Decade Of Change: The 1950s, Calvin Bryon Thomas

History Theses & Dissertations

After World War II, various forces developed or gained momentum which affected families in the fifties. In the 1950s, many men witnessed a decline of authority in the family unit, while women and children achieved new positions of importance. Also, certain values of families deviated from those of earlier generations. Furthermore, family members had more spare time for leisure activities within and outside the home.

Throughout the decade, many young people. began to date, go steady, engage in premarital sex, and marry sooner than in former years. The marriage rate remained fairly high in the decade and the birth rate …

Crack Propagation In Aluminum Sheets Reinforced With Boron-Epoxy, George Lawrence Roderick

Mechanical & Aerospace Engineering Theses & Dissertations

The literature has shown that crack propagation in cracked metal sheets can be significantly reduced by bonding an uncracked reinforcement to the metal sheet. However, cyclic debonding typically occurs over a localized area near the crack. Herein, an analysis was developed to predict both the crack growth and debond growth in a reinforced system. The analysis was based on the use of complex variable Green's functions for cracked, isotropic sheets and uncracked, orthotropic sheets to calculate inplane and interlaminar stresses, stress intensities and strain-energy-release rates. An iterative solution was developed that used the stress intensities and strain-energy-release rates to predict …

Studies Of Fracture And Deformed Surfaces Of High Strength Aluminum Alloys By X-Ray Diffraction, Tamma K. Kumar

Mechanical & Aerospace Engineering Theses & Dissertations

X-ray observations of fatigue fracture and deformed surfaces of 7075-T6 aluminum were conducted in this study. The (111) and (222) diffraction peaks were obtained from the fractured and deformed surfaces. It was observed that in comparison with the base metal, the fracture exhibited line broadening similar to that due to cold working. The broadening is indicative of plastic deformation in the vicinity of the advancing crack tip during the fracture process. Also the different regions of fracture exhibited varying degrees of line broadening. With respect to the fatigue crack, the slow crack growth region showed a greater broadening, and, hence, …

Static Temperature Measurements In Supersonic Flow Using Lasar Raman Spectroscopy, Paul A. Nystrom

Mechanical & Aerospace Engineering Theses & Dissertations

Laser Raman spectroscopy is a nonintrusive technique which can generate mean static temperature (MST) data within flow fields. By ratioing two simultaneously gathered portions of the Raman scattered spectrum, absolute intensity measurements were not needed. This method was applied to a supersonic cold air jet, where the NST ranged from 160'K to 300'K. Accurate measurements were not realized due to the presence of flow contaminates, especially water vapor.

Precise Frequency Control Of The Voltage Controlled Oscillator Using Finite Digital Word Lengths, Timothy Peter Hulick

Electrical & Computer Engineering Theses & Dissertations

For an oscillator that is periodically swept in frequency between some upper and lower bound, the output amplitude may easily be made constant and therefore known with a high degree of certainty. The instantaneous frequency exists only at a point in time and therefore possesses a zero probability of existing at any point. This thesis deals with the development of a method for interchanging the probability density functions of amplitude and frequency so that the latter becomes known with certainty while the former is known only to the extent that it is within a certain range.

The method developed makes …

United States Foreign Policy And Mesopotamian Oil 1923-1928, Robert Francaviglia

History Theses & Dissertations

This thesis views the efforts of American oil interests to participate in the exploitation of Middle East oil resources in the 192Os as a point of departure in United States foreign policy. In its opposition to official involvement in the affairs of private business, the United States Government insisted that American oil companies negotiate directly with the British Government­ dominated companies which controlled the Near and Middle East. By placing the execution of its international oil policy under the control of private industry, the United States Government surrendered its capacity to conduct diplomacy with regard to a vital strategic resource. …

Evaluation Of Hydrogen As A Cryogenic Wind Tunnel Test Gas, Richard Carl Haut Ii

Mechanical & Aerospace Engineering Theses & Dissertations

A theoretical analysis of the properties of hydrogen has been made to determine the suitability of hydrogen as a cryogenic wind tunnel test gas. By using Cryogenic hydrogen, instead of air or cryogenic nitrogen, as the wind tunnel test gas, a significant increase in the test Reynolds number may be achieved without increasing the aerodynamic loads. Under sonic conditions, for example, compared to air at ambient temperature, cryogenic hydrogen at a pressure of one atmosphere produces an increase in Reynolds number of a factor of approximately fourteen while cryogenic nitrogen, at the same pressure, produces an increase of only a …

Fundamental Analysis Of The Linear Multiple Regression Technique For Quantification Of Water Quality Parameters From Remote Sensing Data, Charles Henry Whitlock Iii

History Theses & Dissertations

This thesis is an examination of the role of American policy makers in the transformation of Japan from a defeated, disarmed enemy to a Cold War ally on the path to rearmament during the Allied Occupation (1945-1952). The original Occupation goals of disarmament and demilitarization for Japan were embodied in Article IX of the American-sponsored Japanese Constitution of 1947. These goals were unilaterally discarded. 'by American policy makers as the Cold War developed and U,S. security policy in Asia dictated that Japan be rehabilitated as an ally. Douglas MacArthur presided over the Occupation of Japan almost in its entirety, and …
