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 ... 
Shape optimization for beam structural design
(University of MissouriColumbia, 1988)"Optimization is concerned with achieving the best outcome of a given objective while satisfying certain restrictions. The central purpose of structural analysis is to predict the behavior of known structural configurations ... 
Synthesizing force systems for motion time response, inputoutput forces and joint force control using interactive graphics and influence coefficients
(University of MissouriColumbia, 1984)"THE PRIMARY OBJECTIVES OF LINKAGE DESIGN: The four design objectives most generally encountered when designing a linkage are: Objective 1: Kinematic, a linkage is geometrically designed to meet kinematic objectives such ... 
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 ... 
Wall and inertia corrections to the settling velocity of spheroids
(University of Missouri  Columbia., 1987)"Introductory Remarks: There is a great deal of interest in the relative motion of particles at low Reynolds numbers. The stimulus for these studies has ranged from interest in basic fluid mechanics to investigations of ... 
Relative motion of spheroids at low Reynolds number
(University of MissouriColumbia, 1987)"The term aerosol has been frequently used to describe microscopic liquid and/or solid particles. Initially aerosol particles were thought to be stable when settling in a gravitational field. Later Brownian motion and ... 
Structural and dimensional force system synthesis for one degreeoffreedom planar linkages by using interactive computer graphics
(University of MissouriColumbia, 1984)"INTRODUCTION TO FORSS: In most cases a linkage is designed to meet kinematic inputoutput motion criteria which is then followed by synthesis to satisfy dynamic objectives. Force System Synthesis (FORSS) is the process ... 
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 ... 
A theoretical examination of the growth and attenuation of acoustic and entropy waves in ideal MHD generators
(University of MissouriColumbia, 1988)The results of a theoretical investigation of the interaction between electromagnetic fields and acoustic and entropy waves in a partially ionized gas are presented. The effects of this interaction for combustiondriven ... 
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 ... 
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, ... 
Analytical methods for the pyramidal truss metamaterial
(University of MissouriColumbia, 2023)Mechanical metamaterials are a subclass of metamaterials which exhibit exotic effective mechanical proper ties. These may include a negative bulk modulus, a negative Poisson's ratio, or a negative mass density. Subse ... 
A direct approach for computationally efficient lowthrust trajectory optimization
(University of MissouriColumbia, 2023)This study uses a direct optimization technique to find optimized lowthrust trajectories for spacecraft that minimize fuel consumption. By using analytic orbital averaging, a spacecraft's equations of motion are simplified ... 
Investigation of oxidation mechanisms for aluminum micro and nanoparticles of various geometries via nanosecond laser irradiation
(University of MissouriColumbia, 2023)Aluminum micro and nanoparticles have garnered interest from researchers as solidstate fuel in heterogenous energetic composites due to their high energy density, low cost, and general abundance. To react, aluminum ... 
3D growth simulation and field emission properties of vertically aligned carbon nanotubes
(University of MissouriColumbia, 2023)[EMBARGOED UNTIL 12/1/2024] Since their discovery, carbon nanotubes (CNTs) have become a widely researched and utilized nanomaterial due to their nanoscale size and unique electrical, thermal, and mechanical properties. ... 
Lippmann's legacy : the evolution of electrowetting and its impact on wettability
(University of MissouriColumbia, 2023)In this dissertation, we venture beyond the traditional frameworks of electrowetting to establish a systematized approach to understanding and manipulating fluid surfaces under the influence of electrical forces. Our primary ... 
Strengthening dental amalgams
