Anglo-American Isthmian Diplomacy And The Clayton-Bulwer Treaty, George W. Shipman

Masters Theses

Introduction

The Panama Canal is one of the major commercial waterways of the world and, furthermore, it is vital to the defence of the United States. ·Before this canal could be constructed, it was necessary to persuade the British government to give up its right to share with the United States the building of an isthmian canal. The Clayton-Bulwer treaty of 1850 had provided that neither the United States nor Great Britain would carry out the project singly. Later through the Hay-Pauncefote treaty Great Britain agreed to abrogate the Clayton-Bulwer treaty and allowed the United States alone to build and …

The Utilization Of Artillery And Mortars As Infantry Support Weapons In The Chaco War, Charles John Goodall

Masters Theses

I. The Background of the Conflict

In the summer of 1932, while the world's attention was focused upon Japanese aggression in Manchuria, a border skirmish in the upper reaches of the Plata valley ignited a conflict which could not be extinguished by the good offices of the Pan-American Union or the peace-making machinery of the League of Nations. The prize in question, nearly one hundred and fifty thousand square miles of savanna and swamp, would be minuscule in comparison with the territorial acquisitions of the dictators of that era, but to the two politically unstable and highly nationalistic nations contesting …

United States Dollar Diplomacy In China During The Taft Administration, In Suk Ro

Masters Theses

I. Introduction

The fundamental aims of a nation's foreign policies are national security and the achievement of national objectives through diplomacy. At different periods in American history, the foreign policy of the United States has been designed to advance a variety of aims. It is possible, for example, to speak of missionary diplomacy, moral diplomacy, military diplomacy and dollar diplomacy. The latter characterizes one phase of economic foreign policy in which the administration of President William Howard Taft represents a dramatic turning point. The foreign aid programs of the period after World War II, such as the Marshall plan and …

Studies On The Conversion Of Indole Acetic Acid And Oxindole Acetic Acid By Hygrophorous Conicus, Barbara Ruth Patterson

Masters Theses

"The fungus, Hygrophorous conicus, produces the enzyme, indole acetic acid oxidase, when grown in the presence of indole acetic acid (IAA) or tryptamine. The IAA acts both as an inducer and a substrate for this intracellular enzyme. The product of the oxidation catalyzed by the IAA oxidase is oxindole acetic acid (OIAA). Since the IAA and OIAA absorb maximally at two different wavelengths the use of spectrophotometric analysis was possible for assaying for the IAA oxidase activity. Paper chromatography was used for qualitative identification of the IAA and OIAA. The rate of growth and the rate of formation of the …

Design Of A Photoelectric Transient Torque And Speed Meter, Raojibhai A. Patel

Masters Theses

"There are many situations in which it is desirable to know the speed of the shaft and the torque it is transmitting, when it is equally undesirable to make any mechanical connection to the shaft. This thesis describes the development and design of a device for measuring the torque and speed by photo-electric means. The basic principle is that a light beam parallel to the shaft may be used to pick up the desired information without adding friction to the system. The deflection of a torque tube inserted in the shaft opens or closes a set of apertures arranged in …

A Study Of The Structural Rearrangements Accompanying Room Temperature Recovery Of High Purity Aluminum, Carlos Manuel Lago

Masters Theses

"X-ray methods (Laue back reflection and transmission) and etch pit studies were used in order to follow structural changes in the deformed metallic lattice during room temperature recovery. The accumulative evidence indicates that the deformed lattice undergoes subboundary movements and regrouping of fragments within a few days after stressing. On the basis of a superficial investigation, it was found that fast neutron bombardment increases the rate of room temperature recovery. Through the use of a new etchant, a finer substructure was revealed within the Lacombe subgrain. Glide strain values were determined for the series investigated, and a new approach was …

Comparison Of Methods To Select A Probability Model, Howard Lyndal Colburn

Masters Theses

"A comparison is made between the estimates of the parameters in a gamma distribution obtained by the method of moments with those obtained by a numerical approximation to the maximum likelihood estimates. The estimates obtained by the numerical approximation had a smaller mean squared error from the true value than the estimates obtained by the method of moments. Modifications to tests of fit are made in order to develop methods to select a distribution from a set of possible distributions for a population with an unknown distribution. These selection methods are compared in their ability to make correct selections. Although …

Determination Of The Temperature Distribution Of The Ionized Portion Of The Jet From A Vortex Stabilized Plasma Generator Operating On Argon, G. Douglas Schellman

Masters Theses

"The interim thesis deals with the determination of the temperature distribution of a plasma jet operating on argon. It is the purpose of this thesis to present in detail the experimental process used and make a correlation of the experimental and theoretical results.

A copper enclosure was placed around the protruding flame, and the embedded thermocouple readings were taken and recorded. A stagnation temperature probe was inserted in the enclosure and moved both axially and transversely toward the flame taking readings at each pre-chosen interval. The exit temperature of the jet was obtained from a total energy balance.

From the …

Turbulence In Journal Bearings, Kashyap R. Mehta

Masters Theses

"In this investigation, an experimental study was performed on a journal bearing under laminar and turbulent flow conditions. Using relationships for friction factor developed previously by other investigators a comparison was made with results of this present investigation. Since the flow changes from laminar to turbulent with a change in speed of rotation, curves for friction factor as a function of speed were plotted. Various attempts to make the recording and measuring systems more sensitive were also made and are discussed in this thesis"--Abstract, page ii.

Heat Transfer Coefficients Across Bonds And Contacts, Eugene Charles Fadler

Masters Theses

"The purpose of this investigation was to experimentally determine heat transfer coefficients across interfaces, including the effects of the thermal conductivity of the adherends, the hardness of the adherends, the bond thickness, and the type of adhesive.

Aluminum alloy, steel, copper, and extruded nylon rods were used as adherends; all 1.875 inches diameter and 8 inches long. Each was cut radially at its midpoint and faced off to the desired surface finish. Bare interface tests were conducted before the adherends were bonded together. The adhesives used were high grade silica refractory cement, two-part epoxy resin adhesive, and thermosetting synthetic rubber-phenolic …

Kinetics Of Base-Catalysed Reactions, Kunjvihari Ramanlal Mehta

Masters Theses

"The work of Wulfman on the mechanism of the Michael reactions suggests that the normal Michael reaction is second order kinetically, with the rate being proportional to the concentration of the acceptor and the active form of the addendum. A detailed reaction mechanism of normal Michael reaction was not proposed due to insufficient data which resulted from analytical difficulties. This investigation involves the study of the kinetics of normal Michael reaction from the stand point of base strength, solvent concentration and acidity of the reactants, solvent and products"--Experimental. A. Purpose of Investigation, page 17.

Linear And Quadratic Programming With More Than One Objective Function, William John Lodholz

Masters Theses

"A computational procedure is presented for determining optimal solutions to the linear and quadratic programming problem when there is more than one objective function subject to linear constraints. In general a unique solution does not exist and a set of "best" or "efficient" points is determined and presented in graphical or tabular form. To solve the mathematical programming problems the simplex method is used for linear objective functions and Wolfe's method is used for quadratic objective functions"--Abstract, page ii.

A Photoelastic Study Of The Effect Of Certain Geometric Variables On The Plane Stress Distribution In An Electrical Insulator Body, Richard L. Pendleton

Masters Theses

"Photoelastic models were used to indicate stress patterns in various geometrically designed shapes. Each model represented a two-dimensional cross-section of the interior portion of an axially symmetrical porcelain electrical insulator. Five different loading pins were combined with three loading heads to produce eleven models. The maximum stress in each model was determined using a photoelastic method of stress analysis. An attempt was made to select the best structural design to be used in an electrical insulator. The test results indicate that the most desirable stress distribution is obtained using a single step loading pin and that the loading head angle …

Petrology And Mineralogy Of The "Old Workings Area," El Salvador, Chile, Bertis James Vander Schaaff

Masters Theses

"The 'Old Workings Area,' so called for its early mining by the Incas, is located 4 1/2 miles northeast of the El Salvador Porphyry copper deposit, the third largest copper producer in Chile. The area mapped in this study is shown to consist of rhyolite pebble conglomerate, two volcanic flows, andesite and rhyolite porphyry, and two intrusions. Quartz porphyry and tourmaline-bearing breccia. Petrographic study of surface and drill core rock samples confirms the field nomenclature used for the five rock types. All of the rock types are altered, but the quartz porphyry and andesite are the most intensely altered. Both …

The Dielectric Properties Of A Synthetic Fluor-Mica Formed By Glass-Ceramic Fabrication Techniques, Ray Fred Schumacher

Masters Theses

"A tetrasilicic fluor-mica, K₂Mg₅Si₈O₂₀F₄, was synthesized, utilizing glass forming techniques and subsequent heat treating of the mica glass. Discs, approximately two inches in diameter, were formed and heat-treated at selected temperatures between 700⁰C. and 1150⁰C. for various time periods. Density change, weight loss, shrinkage, and dielectric properties were measured to determine the characteristics of this material"--Abstract, page ii.

Analog Simulation Of A Synchronous Machine, J. Derald Morgan

Masters Theses

"The problem presented here is a study by an analog computer simulation of a synchronous machine under balanced three phase, short-circuit conditions. The purpose is to obtain a solution that is more accurate than one obtained by approximate methods using transient and subtransient reactances as is often done. This simulation is accomplished by using an idealized synchronous machine. The equations relating voltage and currents in the machine, as well as speed and torque, are presented for simulation. The equations for the machine include the saliency of one member, as well as the effect of speed and the damper windings. A …

A Feedback Compensator Design For Linear Control Systems, Thsai-Ten Lin

Masters Theses

"The compensation process in control system engineering is indispensable. The addition of a compensator to a fixed plant can often make the system meet certain specifications easily. In this study an attempt was made to use a general purpose digital computer to design a feedback compensator. The method developed is first to determine the minimum gain of the amplifier and the number of compensator poles and zeros based on the given specifications. then free hand root-loci are plotted, with several combinations of possible compensation variables. These data are used as the open-loop transfer function from which the poles and zeros …

The Effect Of Submerged Jets On The Hydraulic Jump, Harvey E. Jobson

Masters Theses

"Tests were performed in order to determine the effects of forcing submerged jets of water into the base of a hydraulic jump. The specific energy of the water leaving the hydraulic jump, the length and the wave formation properties of the jump which had been modified by the introduction of submerged jets were determined and compared with the same characteristics of a normal hydraulic jump and a hydraulic jump which had been modified by the use of baffle piers.

Test results indicate: (a) the quantity of water flowing through the submerged jets is a primary factor in determining the specific …

Transient Temperature Distribution In A Finite Cylinder And An Infinite Cylinder Subjected To Some Boundary Conditions, Harng-Sen Huang

Masters Theses

"This thesis is concerned with the theoretical heat transfer analysis of solid cylinders. The first problem considered is the transient temperature distribution in a finite cylinder. This cylinder has a uniform initial temperature and a uniform constant surrounding temperature. This case is solved by the separation of variables. Combining the charts for the infinite cylinder and the charts for the infinite plate one can determine the solution to this case easily. If a uniform constant surface temperature is prescribed instead of a surrounding temperature, the solution can be obtained from the previous one by charging the Nusselt number to infinity. …

The Development And Evaluation Of An Experimental Technique To Determine Stress Distribution In Uniformly Loaded Flat Plates, James William Walker

Masters Theses

"This thesis reports and evaluates an experimental technique that was developed to determine and monitor the stresses in a simply supported, uniformly loaded circular plate. Deflections are less than half the thickness of the plate. The application of the developed technique to plates whose integrity has been compromised with holes in various locations is discussed.

Resistance strain gages were used to determine experimentally the stresses in a simply supported, uniformly loaded circular plate with and without a concentric hole. The accuracy of the experimental results was established to be within approximately six percent of theoretical.

Proper application of the experimental …

Cylinder-Head Surface Temperature And Maximum Pressure In A Diesel Engine, Jayant M. Patel

Masters Theses

"This report presents the result of an experimental investigation on the effect of 1) fuel consumption in a diesel engine on the mean cylinder-head surface temperature 2) engine speed and load on the maximum cylinder pressure.

A fast-response thermocouple was fixed in the cylinder head and temperatures were measured for various load and speed conditions. An attempt was made to record a transient surface temperature versus crank-angle diagram. Some doubt as to the reliability of this recording may arise because of the very small amount of time lag in the thermocouple action. This is immaterial to the subject of this …

A Study Of Certain Conservative Sets For Parameters In The Linear Statistical Model, Roger Alan Chapin

Masters Theses

"In the case of the linear statistical model, it has been shown that under certain conditions the confidence intervals obtained by considering the parameters one at a time are conservative when used as a joint confidence region, using the product of confidences as the confidence. However, nothing had been known of how conservative they are. This research provides accurate estimates of the true confidence for these cases.

Also, it has not yet been proved that they are indeed conservative for all cases. It is thought that they are, and the results of this research support this conjecture"--Abstract, page ii.

Investigation Of The Use Of Optics In The Analysis Of Structures, Jimmy D. Hahs

Masters Theses

"This study was made to determine the feasibility of the use of optics in the analysis of structures. Since the curvature of a beam due to a loading condition is a function of the moment, a measure of this curvature is a measurement of the moment.

This study used the relationship between object size and image size formed by a concave or convex reflective surface to determine the radius of curvature and the moment at the point.

Overhanging simply supported beams of plexiglass with concentrated loads at various positions were used to demonstrate the developed optical theory. Optical measurements were …
