An adaptive control strategy for industrial robotic systems
(University of Missouri--Columbia, 1984)Industrial robots in use today lack the ability to perceive and interact with their environment. This limitation is a major obstacle confronting robotic systems developers. This work outlines an adaptive control strategy ... -
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 Missouri--Columbia, 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 ... -
An application of integer/discrete/0-1 programming for nonlinear, conceptual design optimization
(University of Missouri--Columbia, 1987)"The primary goal of this thesis is to establish an algorithm by which the conceptual design and optimal design can be accomplished simultaneously. Take for example, a ten-member bridge truss that is to be constructed; and ... -
Applications of the boundary element method for structural shape optimization
(University of Missouri--Columbia, 1986)In this study, applications of the boundary element method for two- and three-dimensional structural shape optimization are presented. The displacements and stresses of the structure are computed using the boundary element ... -
Cogeneration as related to phosphorus incineration
(University of Missouri--Columbia, 1982)This thesis was completed with two goals in mind. First, a method or technique was used for deducing the optimum cogeneration potential of a typical chemical plant, which may be paralleled to for any given medium to large ... -
A comparison between the plastic work energy criterion and the J-Integral fracture criterion in fatigue crack propagation
(University of Missouri--Columbia, 1985)This thesis attempts to show the correlation between the plastic work required for a unit area of fatigue crack propagation and the J—Integral method of analysis. Fatigue crack propagation rate equations are given for ... -
Design for latitude
(University of Missouri--Columbia, 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 multiple-specimen, reversed-flexure fatigue tester and its application to the testing of titanium sheet
(University of Missouri--Columbia, 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 strength-to-weight ratio is complicated ... -
The effect of mean stress and R ratio on the fatigue behavior of turbine alloys
(University of Missouri--Columbia, 1976)With the advancement of gas turbine engine technology the demand for materials research on turbine alloys has increased. In this research program, two turbine alloys, Ti-6A1-2Sn-4Zr-2Mo and Waspaloy, were observed in respect ... -
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 Missouri--Columbia, 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 Missouri--Columbia, 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, glass-fiber reinforcement and aging on the fatigue behavior of polycarbonate in aqueous and saline environments
(University of Missouri--Columbia, 1977)The effects of molding temperatures, glass-fiber reinforcement, stress concentration, aging and saline environment on the fatigue behavior of injection molded polycarbonate were investigated. Fatigue tests were made with ... -
Energy consumption analysis of cooling tower fan operation
(University of Missouri--Columbia, 1986)"The purpose of this thesis is to present a method to quantitatively evaluate the annual energy consumption of several types of fan control that may be used on cooling towers. The types of fan control considered are: the ... -
Equilibrium composition and thermodynamic property calculation for general hydrocarbon combustion
(University of Missouri--Columbia, 1984)A computer program was developed for the calculation of the equilibrium composition and thermodynamic properties of the high temperature combustion products that results from general hydrocarbon combustion. An ideal gas ... -
Estimates on heat transfer from a conditioned space for average days
(University of Missouri--Columbia, 1982)"Since the early seventies, the cost of energy has risen dramatically. In the late seventies, the amount of energy consumed by the residential sector in this country consisted of twenty percent of the total energy consumed. ... -
Experimental evaluation of spinal fracture stabilization systems : comparison of Luque rectangles, the Kaneda device, and Harrington rods with sublaminar wires
(University of Missouri--Columbia, 1986)"At the University of Missouri-Columbia a spinal stabilization instrument evaluation system was developed by Carson, Gaines, Glascock, Karra, and Pak [3,16] to determine the ability of internal fixation devices to stabilize ... -
Experimental free convection from piping in district heating utilidors
(University of Missouri--Columbia, 1985)Experiments were performed to study the two-dimensional natural convection heat transfer from two isothermal horizontal cylinders to an isothermal cooled rectangular enclosure. The experiments were designed to simulate the ... -
The extension of geometric programming to optimal mechanical design
(University of Missouri--Columbia, 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 non-linear objective function subject to a set of non-linear inequalities. ... -
Free convection in a heat generating porous media in a short cylinder
