Mass Fraction And The Isotopic Anomalies Of Xenon And Krypton In Ordinary Chondrites, Edward W. Hennecke
Mass Fraction And The Isotopic Anomalies Of Xenon And Krypton In Ordinary Chondrites, Edward W. Hennecke
Masters Theses
"The abundance and isotopic composition of all noble gases are reported in the Wellman chondrite, and the abundance and isotopic composition of xenon and krypton are reported in the gases released by stepwise heating of the Tell and Scurry chondrites. Major changes in the isotopic composition of xenon result from the presence of radiogenic Xe¹²⁹ and from isotopic mass fractionation. The isotopic composition of trapped krypton in the different temperature fractions of the Tell and Scurry chondrites also shows the effect of isotopic fractionation, and there is a covariance in the isotopic composition of xenon with krypton in the manner …

Design Of A Semi-Automatic Transmission, Yogendra Prahladray Buch
Design Of A Semi-Automatic Transmission, Yogendra Prahladray Buch
Masters Theses
"Design of a semi-automatic four-speed transmission for automotive engines with moderate horsepower is described. The basic configuration consists of main and countershafts and five pairs of constant-mesh gears. Engine torque is transmitted through an input gear pair to the countershaft, and finally to the output shaft through a selected output gear pair. Selection is accomplished by engaging one of five hydraulically operated clutches located on the countershaft. Engagement fixes the desired gear to the countershaft and engine torque is then transmitted to the mating gear, which is fixed to the output shaft. Fourth speed is obtained by coupling the input …
The Effect Of Diameter On The Film Boiling Behavior Of Liquid Nitrogen, William Joseph Wafer
The Effect Of Diameter On The Film Boiling Behavior Of Liquid Nitrogen, William Joseph Wafer
Masters Theses
"A film boiling heat transfer study was conducted for liquid nitrogen at atmospheric pressure. The heat transfer surfaces used were cylinders with outside diameters of 0.450, 0.650, 0.850, and 1.000 inches. The temperature differences covered were from approximately 150ºF to approximately 600ºF. The data indicate that the heat flux will decrease to a minimum then increase slightly as the diameter of the heat transfer element is increased at constant temperature difference. The heat transfer coefficient is expected to approach a flat plate correlation as the diameter approaches infinity"--Abstract, page ii.
Free Vibrations Of Circular Cylindrical Shells, Sushil Kumar Sharma
Free Vibrations Of Circular Cylindrical Shells, Sushil Kumar Sharma
Masters Theses
"In this report bending theory of shells is used to determine the natural frequencies and mode shapes of circular cylindrical shells. The governing eighth-order system of differential equations has been put in a form which is especially suitable for numerical integration and application of different sets of homogeneous boundary conditions. The Holzer method is used to solve the eigenvalue problem. During numerical integration of the differential equations, the exponentially growing solutions are suppressed whenever they become larger than previously selected values. Numerical results are obtained for various shell geometry parameters and for three different sets of homogeneous boundary conditions. These …
A Triangular Element For Numerical Solutions Of Axisymmetric Conduction Problems In Cylindrical Coordinates, Prafulla Chandra Mahata
A Triangular Element For Numerical Solutions Of Axisymmetric Conduction Problems In Cylindrical Coordinates, Prafulla Chandra Mahata
Masters Theses
"The triangular element is one of the many suitable elements which are used in finite difference methods as applied to conduction heat transfer. Such elements find many applications in conduction problems in Cartesian coordinates. This work proposes a new triangular element for axisymmetric conduction problems in cylindrical coordinates. The validity and workability of the networks formed by the proposed triangular elements are strengthened by selected examples. The work is completed by the application of the triangular element to an industrial problem having irregular boundaries. The results are compared with the solution obtained by the finite element method"--Abstract, page ii.
The Integrated Planning Method Of Project Planning, Development And Implementation, Joseph Frank Lynch
The Integrated Planning Method Of Project Planning, Development And Implementation, Joseph Frank Lynch
Masters Theses
"Present comprehensive planning endeavors lack a consistent methodology which will produce realistic, useable results. The validity of this statement should be obvious after one has read Miller's "Evaluation of City and Region Planning Techniques." This paper contains a methodology, "The Integrated Planning Method," which will go a long way toward correcting this gross inadequacy that planners presently encounter in directing planning efforts. Two government developed planning and analysis procedures that, up until this time have been applied almost exclusively to hardware systems, have been combined into one integrated planning methodology that will provide not only meaningful and rigorous definition and …
Evaluation Of A Cation Isotopic Substitution Technique In Conjunction With A High Temperature Gas Pycnometer For Determining The Stoichiometry Of Materials, Michael Clair Graves
Evaluation Of A Cation Isotopic Substitution Technique In Conjunction With A High Temperature Gas Pycnometer For Determining The Stoichiometry Of Materials, Michael Clair Graves
Masters Theses
"This study was concerned with the evaluation of a high temperature gas pycnometer, used in conjunction with a cation isotopic substitution technique, for determining the stoichiometry of materials. Three methods were investigated for determining the correction factors for the thermal gradient effects in the gas pycnometer. The correction factors were shown to be dependent on the temperature, the sample volume, and the height of the sample in the sample chamber. Under the conditions of these experiments, the correction factors were shown to be essentially independent of sample grain size and pycnometer atmosphere. The determination of the stoichiometry of cadmium oxide …
Some Factors Affecting The Results In Cyclic Triaxial Tests, Suresh Kumar Chaudhary
Some Factors Affecting The Results In Cyclic Triaxial Tests, Suresh Kumar Chaudhary
Masters Theses
"A major cause of damage to structures and earth embankments during earthquakes or any other such dynamic vibrating loading conditions has been the liquefaction of saturated sands. There have been several investigations to establish a convenient and relatively simple laboratory test procedure and to study the nature of field conditions leading to sand liquefaction. This investigation evaluates the effects of sample size, testing frequency, and the method of sample preparation on the number of cycles to cause initial liquefaction in pulsating triaxial tests using standardized equipment and test procedures. It has been found that sample size does affect test results …
Contractor Quality Control: A Method Of Construction Inspection, John Scott Treadwell
Contractor Quality Control: A Method Of Construction Inspection, John Scott Treadwell
Masters Theses
"It has become apparent in recent years that the United States Government's construction contract supervision and administration procedures are causing an increase in contractor claims and disputes and that the system itself is becoming prohibitively expensive. To deal with some of these problems, the Department of Defense is attempting to implement a new approach to construction inspection--Contractor Quality control. Under the Contractor Quality Control System the majority of the standard contract inspection and testing responsibilities are placed on the contractor, and the Government relinquishes its traditional step-by-step inspection and testing procedures and withdraws to a position of contract surveillance. The …

Triangular Signal Stabilization Of Nonlinear Systems, Kamaleddin Yadavar Nikravesh
Triangular Signal Stabilization Of Nonlinear Systems, Kamaleddin Yadavar Nikravesh
Masters Theses
"Many nonlinear systems display self-sustained oscillations which are often undesirable. The stabilizing effect of a high frequency input signal on an oscillating system with one nonlinearity is determined by the characteristics of the nonlinear element in the system, the linear portion of the system and the amplitude of the signal. This investigation has been concerned with the effect of a triangular wave stabilizing signal on these self oscillations. The equivalent gains for several common nonlinearities are derived. The pseudo describing function introduced by Oldenburger and Boyer for sinusoidal stabilization has been extended to the triangular wave case, and it is …
