Evaluation Of City And Region Planning Techniques, Charles Clay Miller
Evaluation Of City And Region Planning Techniques, Charles Clay Miller
Masters Theses
"The transportation and community planning effort in the United States has resulted in the expenditure of a great deal of time and money. However, the result of this effort has largely been unusable because of a lack of an effective formalized planning method. this thesis presents summarizations of the planning methods employed in ten plans which are typical of the U.S. Planning Effort. Each of these methods are critiqued in the light of a proposed planning method. The Federal Government has recently required the adoption of a Planning, Programming and Budgeting System (PPBS) in an effort to formalize a scientific …
Analysis And Control Of Noise Produced By Small Pneumatic Tools, Phillip Ray Elam
Analysis And Control Of Noise Produced By Small Pneumatic Tools, Phillip Ray Elam
Masters Theses
"Noise measurements were made near the exhaust of three small pneumatic tools operating under various loads and with various components removed. One-third octave analyses were performed on the noise for identification of noise sources and to determine possible noise reduction techniques. It was determined that the noise spectra consisted of broad band turbulent flow noise plus periodic components at the tool motor blade passage frequency and harmonics of this frequency. One tool, the nut setter, was selected for reverberant field noise analyses and noise reduction studies. Reverberant field measurements indicated that most of the tool noise was transmitted through the …
Computerized Methods For Estimating Heating-Cooling-Ventilating System Usage In All-Electric Buildings, Carl William Glaser
Computerized Methods For Estimating Heating-Cooling-Ventilating System Usage In All-Electric Buildings, Carl William Glaser
Masters Theses
"This thesis develops a method and a resulting computer program for estimating the energy input required by the heating-cooling-ventilating system of a building. The computer program has the ability to model the ventilating system and all the inefficiencies introduced when the heating system is allowed to fight the cooling system to provide temperature control within the conditioned space. The program also can consider mechanical heat reclaim accurately, making the consideration on a time of need versus a time of occurrence basis. The program is written to utilize input data in rather simplified form. This allows the program to be used …
Fault Detection In Asynchronous Sequential Circuits, Jeng-Chuan Kau
Fault Detection In Asynchronous Sequential Circuits, Jeng-Chuan Kau
Masters Theses
"As the asynchronous sequential circuit has become more and more important to digital systems in recent years high reliability and simple maintenance of the circuit is stressed. This paper presents a fault-detection algorithm which will be applicable to most of the practical asynchronous sequential circuits. The asynchronous sequential circuit is treated from the combinatoric point of view. First the minimal set of states, both stable states and unstable states, sufficient to detect all possible faults of the circuit is found from the fault table. Then a test sequence is generated to go through these states. It is assumed that testing …
A Mathematical Model For The Neutron Dependence Of Neutral Base Region Recombination, Jonas Bereisa Jr.
A Mathematical Model For The Neutron Dependence Of Neutral Base Region Recombination, Jonas Bereisa Jr.
Masters Theses
"A discrete, deterministic, mathematical model is developed for the neutral bulk base region of graded base devices which accounts for both the effects of recombination and the built-in electric field in the bulk base region at low, intermediate, and moderate current/injection levels. This model is applied to a study of neutron radiation effects in double diffused silicon transistors. Exact expressions are developed for the injected emitter, base and collector currents, the base recombination term, and the ratio of base current increase to collector current decrease as functions of device geometry, impurity profile, and neutron fluence. Neutron-induced current gain degradation is …

Effect Of Third Components On Drag Reduction In Aluminum Soap-Hydrocarbon Systems, Kun-Chieh Lee
Effect Of Third Components On Drag Reduction In Aluminum Soap-Hydrocarbon Systems, Kun-Chieh Lee
Masters Theses
"The effect of additives, aging, shear and peptizing agents on the drag reducing abilities of aluminum disoaptoluene solutions prepared at room temperature were studied. Viscosity measurements were used as a primary test to select effective additives. Medium strong organic bases were found to be useful as they speed up the dissolution of slow dissolving aluminum dioctoate soap and form large micelle structures. These peptizers are not effective with aluminum distearate which is very hard to dissolve in toluene at room temperature. Turbulent flow pressure drop measurements at various aging times were made for solutions of 0.1 per cent aluminum dioleate …
Imperfections In The Ag-In System (Alpha-Phase) And Lattice Parameters Of Cadmium Oxide, Prafulla Maganlal Vora
Imperfections In The Ag-In System (Alpha-Phase) And Lattice Parameters Of Cadmium Oxide, Prafulla Maganlal Vora
Masters Theses
"This thesis has been divided into two parts, namely, "Imperfections in the Ag-In System (Alpha-Phase)" and "Lattice Parameters of Cadmium Oxide." Imperfections in the Ag-In System (Alpha-Phase): It can be shown -- as in the case of the Cu-In α solid solutions -- that during quenching from the liquid state, strains are produced by the quenching process and, in addition, vacancies are quenched-in, in the Ag-In α-solid solutions. The number of vacancies present, measured by the decreased density of the alloys, is proportional to the indium content up to the solid-solubility limit. Upon heat treatment of the alloys, the thermal …
The Possible Correlation Of Carcinogenic Activity With Electronic Structure Of Benz(A)Anthracene, Patricia Joan Blair
The Possible Correlation Of Carcinogenic Activity With Electronic Structure Of Benz(A)Anthracene, Patricia Joan Blair
Masters Theses
"The electronic structure of benz(a)anthracene based on the sigma and pi electrons was predicted by the modified intermediate neglect of differential overlap (MINDO) molecular orbital method and compared with the pi electronic structure determined by the Pople method. The crystalline molecular structure was used for both methods. The Pople calculation was also done on the aromatic molecular structure and a combination structure which assumed the bond lengths of the crystal structure and the bond angles of the aromatic structure. Chemical properties predicted by the MINDO and POPLE electronic structures were compared; the MINDO results provided the best agreement with experimental …

Interface Thermal Conductance With Metal Screens As Interstitial Material, William Edward Stewart Jr.
Masters Theses
"This thesis reports the results of an experimental investigation to determine the thermal conductance at the interface of metal specimens separated by wire mesh. Sets of metal specimens of copper, 2024-T4 aluminum, and 304 stainless steel were used. The specimens were cylindrical, axially aligned, and hydraulically loaded. All tests were conducted in an air environment. Pressure applied to the specimens ranged from 50 to 500 psig. Surface roughness of the interfaces varied from 5 to 20 micro inches. The wire mesh separators were of 304 stainless steel in 20, 30, 40, and 50 mesh. Results of the experiments show that: …
Transient Response Of A Vibration Isolation System, Hemendra Shantilal Acharya
Transient Response Of A Vibration Isolation System, Hemendra Shantilal Acharya
Masters Theses
"A practical procedure for investigating the performance of a vibration isolation system under transient conditions is presented. For this investigation, an induction motor with an unbalanced rotor is studied during the period when it accelerates to its operating speed from rest. Using Newton's second law of motion, equations of motion are derived, first neglecting and then considering the effect of "inertia torque". This torque is produced by the inertia force resulting from vertical acceleration of the unbalanced mass. The equations are solved on a digital computer using the Runge-Kutta method of order 4. The results obtained are compared with those …
Measurement Of The Surface Energy Of Rock By The Three-Point Bending Of Notched Beams, John Walter Corwine
Measurement Of The Surface Energy Of Rock By The Three-Point Bending Of Notched Beams, John Walter Corwine
Masters Theses
"In this investigation, the surface energy of a medium-grained igneous rock (Barre granite) was measured by breaking small, notched beams in bending. The technique was adapted from fracture toughness tests that have been used with metals and ceramics. The equations used for the calculation of surface energy were derived from several writers' equations for the stress intensity at the end of a notch in a beam subject to bending. Beam thickness, notch width and mineral occurring at the notch tip were evaluated for their influence on the calculated values of surface energy. The surface energy values obtained were used in …
The Assignment Problem And A Suboptimal Solution Technique, William Barry Gregory
The Assignment Problem And A Suboptimal Solution Technique, William Barry Gregory
Masters Theses
"A technique is presented which finds a fast suboptimal solution to the assignment problem. This same technique is then applied to two large dynamic programming problems for which the optimal solution is not known. These examples illustrate how easily this technique can be applied and that it is better than most optimizing techniques because it is fast, cheap and only minor hand calculations are needed. The effect of different initial solutions and their value are compared and it is found that the initial solution is not as significant in a suboptimal technique as in an optimizing technique. The initial solution …
Vibration Of A Rotating Cantilever Beam With An Independently Rotating Disk On The Free End, Darrell Blaine Crimmins
Vibration Of A Rotating Cantilever Beam With An Independently Rotating Disk On The Free End, Darrell Blaine Crimmins
Masters Theses
"This thesis provides a vibration analysis of a rotating cantilever beam with an independently rotating thin circular disk on the free end. The exact differential equations of the system as defined by classical Bernoulli-Euler beam theory are written using the methods of the calculus of variations. The exact equations are not solved, but two different approximations are found by assuming a cubic polynomial deflection curve and applying the equation of Lagrange. The solutions are restricted to small deflections of the beam and a shaft stiffness which permits a deflection in only a single plane. Nonlinear differential equations result in the …
Failure Of Lined And Unlined Small-Scale Cavities In Rock-Like Materials, Seung-Ki Yang
Failure Of Lined And Unlined Small-Scale Cavities In Rock-Like Materials, Seung-Ki Yang
Masters Theses
"The strain conditions around statically loaded circular openings in rock-like materials and corresponding cavity-wall displacements were determined experimentally with resistance strain gages. The models were fabricated with lined and unlined openings simulating underground tunnels. Tests were performed with models of two different materials in plane stress and plane strain. Rock-like materials were designed and the strain gages were embedded at selected points within each model. The models often failed by tensile splitting through the opening early in the loading cycle causing the strains at certain points to deviate considerably from the theoretical values. Tangential strains on the vertical axis were …
Use Of Waste Glass As Asphaltic Concrete Aggregate, Charles Wayne Foster
Use Of Waste Glass As Asphaltic Concrete Aggregate, Charles Wayne Foster
Masters Theses
"The problem of solid waste disposal increases each year, with the annual growth in quantity of solid waste making the present means of disposal even more inadequate. Recycling of solid waste materials is an increasingly popular approach to the disposal problem. The glass component of solid waste is a very promising candidate for recycling, and this investigation studies the possibility of using waste glass as an aggregate for bituminous concrete mixtures. Objectives of this research were to determine whether a glass-asphalt mixture could be designed to meet the Marshall design criteria specified by The Asphalt Institute, to study the amount …
Multi-Stage Shear Testing Of A Cohesionless Soil, Robert Clyde Gullic
Multi-Stage Shear Testing Of A Cohesionless Soil, Robert Clyde Gullic
Masters Theses
"The multi-stage test is a procedure by which a soil's shear strength parameters can be evaluated by the use of a single sample of the material. The object of the investigation is to evaluate to what extent multi-stage testing can be used on a cohesionless material. Three types of tests, using conventional and multi-stage procedures are evaluated. They are: direct shear/consolidated drained, triaxial compression/consolidated drained and triaxial compression/consolidated undrained shear tests. It was found that multi-stage testing can easily be performed and the shear strength parameter thetaf obtained from these tests are in good agreement with those obtained from …
