Analysis And Simulation Of Stepping Motor Systems Using A Phase Plane Approach, Raymond Gerard Gauthier

Doctoral Dissertations

Stepping motors have become an increasingly popular electromechanical interface device, due to their increased reliability and lower costs over the D.C. Servo motor. The inherent open loop mode of stepping motor operation results, under certain circumstances, in a failure mode in which the output of the stepper no longer follows the input commands. In the past, it has been difficult for the designer to define the failure modes and it has not been obvious how to avoid them.

It is the intent of this dissertation to present a mathematical model for a class of stepping motors, the permanent magnet stepping …

Negative Ion Charge Transfer Of The Reaction Of S⁻ And O⁻ With Atomic Hydrogen Producing H⁻ Ions From 1500 To 10 Kev, George F. Hagner

Doctoral Dissertations

"The charge transfer reactions of 0^-, S^- with atomic hydrogen were studied from 1.5 to 10 KeV, and the reaction Cl^- + O₂ + O₂^- + Cl was studied from 10 eV to 10 KeV. The reactions studied were normalized to the reaction H^- + H + H + H^-. The maximum measured cross sections were 4.6 x 10^-16 cm² for the reaction Cl^- + O₂ + O₂^- + Cl and 4.4 x 10^-15 cm² for the reaction 0^- + H …

Phase Equilibria In Aqueous Magnesium Chloride, Sulfate, Chromate And Phosphate Systems, Ladawan Urwongse

Doctoral Dissertations

"In the first part of the present study, which is presented in Paper I, solubility of MgO in aqueous HCl solutions at 23° ± 3°C was measured and combined with analyses of neat magnesium oxychloride cements to construct an equilibrium phase diagram for the system MgO-MgCl₂-H₂O. Invariant liquids in equilibrium with Mg(OH)₂ and 5Mg(OH)₂·MgCl₂·8H₂O (5.1.8), with 5·1·8 and 3Mg(OH)₂·MgCl₂·8H₂O (3·1·8), and with 3·1·8 and MgCl₂·6H₂O were located at 0.8 ± 0.2 MgO, 17.0 ±0.5 MgCl₂; at 1.0 …

I. Extracellular Metabolites From Coprinus Macrorhizus Microsporus. Isolation And Characterization Of Hydroxylagopodin B. Ii. The Cell Wall Composition And Structure Of Coprinus Macrorhizus Microsporus, Carey Bernard Bottom

Doctoral Dissertations

“A purple pigment excreted into the culture medium of a mutant strain of the basidiomycete, Coprinus macrorhizus var. microsporus (ATCC 34960) has been isolated and characterized as hydroxylagopodin B based on ultraviolet, infrared, and mass spectral data. A wild-type strain of C. macrorhizus microsporus does not produce the purple pigment, however it does produce lagopodin B which is yellow in solution. Identification of lagopodin B was based on its melting point, the purple color of its alkaline solution, the mass spectrum, and mobility equivalence with a standard by thin-layer chromatography. The production of hydroxylagopodin B in the mutant strain is …

Locally Quasi-Uniform Structures And Strongly Complete Quasi-Uniform Structures, Shirley Carpenter Huffman

Doctoral Dissertations

"Locally quasi-uniform spaces are studied, and it is shown that a topological space (X,t} admits exactly one compatible locally quasi-uniform structure if and only if tis finite.

A general topological result is given showing that a topological space with an infinite topology has either an infinite ascending or an infinite descending sequence of open sets.

The concept of aw-space is introduced, and it is ii shown that every w-space admits a strongly complete quasi-uniform structure. Also, a characterization of w-spaces is given showing when the fine quasi-uniform structure is equal to the fine locally quasi-uniform structure.

An example is given …

Inferences On The Shape Parameter Of The Gamma Distribution And Cramer-Rao Lower Bounds From Censored Data, James Wyckoff

Doctoral Dissertations

"This dissertation is presented in publication form and consists of two articles. The first article considers inferential procedures on the shape parameter of a gamma distribution from censored sampling. Moments for the statistic T = log(x̅_r/x͠_r) are found and used to derive a two-moment chi-square approximation for T. This approximation is then used for testing, estimating, and setting confidence bounds on the shape parameter of a gamma distribution. The second article concerns the Cramér-Rao lower bounds for the variances of estimators, where the estimators are based on censored data. Convenient techniques are derived to evaluate the …

Some Selection And Ranking Procedures For The Two Parameter Weibull Distribution, Joseph Victor Kingston

Doctoral Dissertations

"This dissertation investigates some selection and ranking procedures for two or more Weibull populations. In particular it studies a restricted subset selection procedure when the populations have a common shape parameter, a 'pick the one best ' procedure for different shapes, classification procedures for both cases, simultaneous and 'best population' confidence intervals for both cases, and, finally, the problem of selecting the one population with largest or smallest shape. Except for the last problem named, the populations are ranked by their reliability. All procedures employ estimates of the parameters of interest based on either uncensored or Type II censored samples. …

The Paleontology And Biostratigraphy Of The Lower Ordovician Gasconade Formation Of Missouri, Bruce L. Stinchcomb

Doctoral Dissertations

"The biostratigraphy, paleoecology and paleontology of the Lower Ordovician Gasconade Formation in Missouri is reinvestigated in an attempt to solve problems that have arisen since the classic earlier studies by Ulrich, Bridge and others. Twelve faunal zones are established, many based on primitive mollusks which dominate the formation. The oldest of these, in the Van Buren Member, is the Hypseloaonus Zone. This is followed by a zone characterized by the primitive cephalopod Dakeoaeras then a zone dominated by the gastropod Sinuopea. These zones are succeeded by the Euomphalopsis, Matthevia and Ozarkina Zones which lie stratigraphically below the Cryptozoon Zone, …

Cellulase Production By Fermentation With Trichoderma Viride On Cellulose And Wood Wastes, Nguyen Huu Kho

Doctoral Dissertations

"Cellulase production by the fungus Trichoderma viride QM 6a and the use of this cellulase for cellulose hydrolysis were studied using Solka Floc cellulose and waste wood (oak) as substrates. The fermentation produced higher enzyme concentration solutions with media containing additional amounts of soy peptone and KH₂PO₄.

The kinetics of fermentation in fermentors and shake flasks of Solka Floc and sawdust were investigated, and equations were selected to express the relationship of the rates of growth and enzyme production with cell mass, enzyme concentration and substrate remaining in the media.

Agitation and aeration decrease the enzyme …

Adaptive Control Of A Cloud Simulation Chamber Expansion System, Katiya Greigarn

Doctoral Dissertations

"This dissertation describes the design and construction of a closed-loop computer controlled expansion system for a cloud simulation chamber. The chamber is used to simulate atmospheric phenomena for the study of microphysical processes. In order to accomplish this, the sample gas inside the chamber must be expanded adiabatically. This means the wall temperature and the gas temperature must be made to agree as closely as possible. The wall is cooled by thermoelectric modules, and the temperature is controlled by analog controllers. The gas is cooled by the adiabatic expansion, and the corresponding pressure is controlled by a laboratory minicomputer, a …
