An analysis of flow induced acoustic resonance in cavities
(University of Missouri  Columbia., 1970)"Interest in cavity flows originated within the aircraft industry when buffeting in open bomb bays and cockpits of military aircraft became a matter of concern with regard to the structural loading on the aircraft. There ... 
An analysis of the induction time in the acetylene oxygen reaction
(University of MissouriColumbia, 1971)"The importance of hydrocarbon combustion in flames and explosions of gases has long been recognized and hence continues to attract intensive investigation. Even though many new results are presented each year the proposed ... 
Applications of the boundary element method for structural shape optimization
(University of MissouriColumbia, 1986)In this study, applications of the boundary element method for two and threedimensional structural shape optimization are presented. The displacements and stresses of the structure are computed using the boundary element ... 
Design for latitude
(University of MissouriColumbia, 1986)"The purposes of this thesis are threefold: (1) to provide an introduction to the Taguchi philosophy and its methodologies, (2) to integrate the Taguchi philosophy of quality loss with nonlinear programming both without ... 
Development of a multiplespecimen, reversedflexure fatigue tester and its application to the testing of titanium sheet
(University of MissouriColumbia, 1971)"Advancing technology constantly increases the demands on existing engineering materials. These demands are extremely severe for aerospace materials where the necessity for a higher strengthtoweight ratio is complicated ... 
The effect of stress ratio, maximum stress, stress amplitude and yield strength of materials on fatigue crack closure of 2024 aluminum and 4130 steel
(University of MissouriColumbia, 1983)Crack closure presented by Elber in 1968 was hoped to modify Paris’ Law in analyzing fatigue crack propagation. Validity of crack closure phenomenon was investigated by many researchers and conflicting results were presented ... 
Effects of constraint variation on the fatigue growth of surface flaws
(University of MissouriColumbia, 1985)Studies have shown that fatigue growth of semielliptic surface flaws in plates is not adequately predicted solely by stress intensity factor analysis. The variation in stress field triaxiality along the flaw border must ... 
Effects of molding variables, glassfiber reinforcement and aging on the fatigue behavior of polycarbonate in aqueous and saline environments
(University of MissouriColumbia, 1977)The effects of molding temperatures, glassfiber reinforcement, stress concentration, aging and saline environment on the fatigue behavior of injection molded polycarbonate were investigated. Fatigue tests were made with ... 
The extension of geometric programming to optimal mechanical design
(University of MissouriColumbia, 1971)Geometric programming was developed in the early 1960's by Clarence Zener, Richard J. Duffin, and Elmore L. Peterson as a method for minimizing a nonlinear objective function subject to a set of nonlinear inequalities. ... 
A holographic interferometry study of an axisymmetric shockwave/boundarylayer strong interaction flow
(University of MissouriColumbia, 1986)An experimental study of the axisymmetric shockwave/ turbulent boundarylayer stronginteraction flow generated in the vicinity of a cylindercone intersection has been conducted. The present data are useful in the ... 
Measurements and analyses of nasal and oral airflow during isolated sound productions by normal and cleft palate speakers
(University of MissouriColumbia, 1971)Speech sound is produced through the superimposition of a coordinated series of progressive and dynamic processes. These processes include respiration, phonation, resonance, and articulation and are accomplished by making ... 
Modeling and optimization of anaerobic swine waste digestion systems
(University of MissouriColumbia, 1985)Mathematical models of the digestion process, an anaerobic digestion system, and an economic analysis of a digestion system were developed. The goal was to accurately simulate the performance of a facility producing less ... 
On the solution of external laminar free convection to power law fluids
(University of MissouriColumbia, 1971)"Pseudoplastic fluids (power law fluid index N [less than] 1), dilatant fluids (N>1), and even Newtonian fluids (N=1) are commonly called power laws fluids, because they show an empirical shear stress (T)strain rate ... 
An optical crosscorrelation technique for turbulent density measurements in flames
(University of MissouriColumbia, 1973)A crossedbeam schlieren (cbs) system has been constructed and used to study the structure of an open, premixed propaneair flame that was pilotstabilized on a twodimensional burner. The cbs is composed of two perpendicular ... 
An optical lateral control system for vehicles
(University of MissouriColumbia, 1971)"It is evident that we will need a new mode of highway transportation within the next fifteen years. There are already 103 million vehicles (cars, trucks, and buses) on our roads; the majority of which are concentrated in ... 
The parametric response of beamcolumns of variable crosssection resting on an elastic foundation
(University of MissouriColumbia, 1973)This investigation studied the problem of the parametric instability of a beamcolumn with variable crosssection resting on an elastic foundation. The problem was analyzed both theoretically and experimentally. The equation ... 
The prediction of concentration and residual stress due to high temperature electroplating
(University of MissouriColumbia, 1970)This research was carried out to further investigate the high temperature electroplating process, in particular, to develop simple computer programs to evaluate the concentration and residual stress present. The programs, ... 
Program for optimization of experimental data within a constrained configuration
(University of MissouriColumbia, 1975)"The purpose of this thesis is to discuss and evaluate the development of a computer program for the optimization of a variable within a constrained situation. The objective of the program is to determine what combination ... 
Pulsatile viscous flow in flexibleelastic tubes
(University of MissouriColumbia, 1971)The flow of an incompressible viscous fluid through a circular tube has received considerable attention during the past fifteen years, both for steady flow and for pulsatile flow. The practical application of blood flow ... 
Reduction of shaking forces in a slider crank mechanism
(University of MissouriColumbia, 1970)The object of this study was to determine the periodic angular speed of the crankshaft of a slider crank mechanism which will minimize the shaking forces and torque of the mechanism on the block. Both the inertial shaking ...
