Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
for an eccentric-circular cam design and a one-cam one-pulley design. By iteratively determining the bow limb, cam, and cable positions a relationship between the drawn length and drawn force will produce a draw-force curve. In fact, this curve represents...
Investigation of static interfacial fracture in orthotropic-orthotropic composite bimaterials using photoelasticity
(University of Missouri--Columbia, 2009)
The effects of static Mode I (opening mode) and mixed-mode (both Mode I - opening mode and Mode II - shear mode present) loading on orthotropic-orthotropic bimaterial interface cracks and isotropic-orthotropic bimaterial ...
Helical tool geometry in stability predictions and dynamic modeling of milling
(University of Missouri--Columbia, 2007)
in an effort to validate TFEA results for machining Ti6Al4V using a helical tool....
Local free convection to non-Newtonian fluids from a horizontal, isothermal cylinder
(University of Missouri--Columbia, 1972)
The transfer of heat between a body surface and the motionless fluid surrounding it is perhaps one of the most naturally occurring physical phenomena. Undoubtedly interest and speculation regarding this natural or free ...
Analytical earth-aerocapture guidance
(University of Missouri--Columbia, 2020)
Aerocapture is a technique of employing a single atmospheric pass to inserts a spacecraft from a hyperbolic orbit, approaching from deep space, into an elliptical (captured) orbit around its destination planet. After ...
Force system synthesis to produce a desired time response of mechanisms
(University of Missouri--Columbia, 1975)
A technique and computer programs are developed which will synthesize parameters of force systems which will drive a mechanism to have a desired motion-time response and desired input-output forces. The force devices can ...
Semi-analytical terminal and automatic approach and landing trajectory planners for unpowered reusable launch vehicle
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A new guidance scheme for the terminal area energy management (TAEM) phase of an unpowered reusable launch vehicle (RLV) has been developed. The main ...
An investigation into thermoelectric coolers
(University of Missouri--Columbia, 2018)
A thermoelectric cooler (TEC) is a type of cooler that uses the electricity between the junction of two materials to cause a temperature drop. These coolers operate using the Peltier effect. Effectively, a TEC uses electrical ...
Nonlinear mechanics and testing of highly flexible one-dimensional structures using a camera-based motion analysis system
(University of Missouri--Columbia, 2006)
Both experimental and theoretical investigations are conducted for the dynamics of cables and strings. The exact equations of motion for finite but small amplitude vibration of string were derived based on a fully nonlinear ...
Numerical and experimental investigations on capillary-driven thin-film evaporation with applications in pumped two-phase loop and loop thermosyphon
(University of Missouri--Columbia, 2020)
and tubular wick posts. The evaporation mode transition from flooded to thin-film evaporation was detected by the evaporator thermal resistance which is directly related with the liquid level in the monolayer wick base. In Chapter 4, an active flow control...
Experimental investigation of liquid metal emulsion effect on the heat transfer performance of an oscillating heat pipe
(University of Missouri--Columbia, 2022)
This thesis introduces an oscillating heat pipe (OHP) charged with a hybrid fluid of gallium and ethanol. The hybrid fluid is fabricated using an ultrasonication technique to produce an emulsion-based mixture of liquid ...
System modeling and control design of a two-stage metering poppet-valve system
(University of Missouri--Columbia, 2006)
control methods that comprise modified PI control, LQG control, H [mobius] control, and nonlinear feedback control are used to make a closed-loop poppet system. The nonlinear controller is only applied to the nonlinear system and certified by Lyapunov...
X-ray topography techniques for the analysis of laser irradiated silicon
(University of Missouri--Columbia, 2005)
There is currently much interest in femtosecond scale laser interactions with materials. Comparison of the damage produced by the femtosecond laser pulses to the longer laser pulses is also of interest. This study examined ...
Theoretical analysis of heat and mass transfer processes in an evaporative cooling system with zeolite desiccant powered by solar energy
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Concerns about energy sources depletion and environmental pollution issues have been raised and is a top priority of the global community. Refrigeration ...
Sensitivity analysis and optimal design of conventional and magnnetorheological fluid brakes
