Parametric and optimal design of modular machine tools
(University of Missouri--Columbia, 2007)
Over the years machine tools for manufacturing have developed into two classes. One is the general purpose machine tools, and the other is designed for machining large quantities of a specific part or process. These ...
Experimental investigation of nanofluid oscillating heat pipes
(University of Missouri--Columbia, 2006)
An experimental investigation was conducted of oscillating heat pipes (OHP) charged with diamond nanofluid. By combining the high thermal conductivity of nanofluids with the high heat transport rate of OHPs, a new type of ...
Investigation of the performance of an automatic arterial oxygen controller
(University of Missouri--Columbia, 2018)
trial at the NICU of the MU Women's and Children's Hospital. The crossover design was used for the clinical trial to allow within-subject comparison and to eliminate interpatient variability. Two human subjects, with two different target ranges of SpO2...
Kinematic analysis of cam profiles used in compound bows
(University of Missouri--Columbia, 2009)
The first compound bow was invented in Missouri in 1969. [Allen, 1968] Compound bows are uniquely different from other types of bows in that they use a set of cables, cams and pulley, and two elastic limbs that act as ...
Experimental and numerical investigation of subcritical bifurcations in milling
(University of Missouri--Columbia, 2007)
The focus of the current thesis is an experimental and numerical investigation of subcritical bifurcations in milling. More specifically, several researchers have reported results indicating that the secondary Hopf ...
Galilean moon tour using simplified trajectory computational techniques
(University of Missouri--Columbia, 2006)
It is desired to find a trajectory for a spacecraft that will capture into an orbit about Jupiter and then subsequently capture into an orbit about each of the Galilean moons. The two main variables are the mass ratio, ...
Bifurcation analysis and damage detection in mechanical structures
