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, …

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 …

Lower Mississippian Sedimentation In Northwestern Montana, Forest E. Haines

Doctoral Dissertations

"Thirty-three measured sections, nine with thin sections and insoluble residues, were studied to determine the depositional history of the Allan Mountain Limestone and the lower member of the Castle Reef Dolomite of the Madison Group in northwestern Montana.

The Allan Mountain base is a fossiliferous limestone, herein named the Brownback Gulch Member, which thickens and becomes cherty to the southwest where the section at Lone Butte resembles that of the Bridger Range Waulsortian-type reefs. A crinoidal lag deposit marks a dis- conformity at the top. In the overlying silty limestone member a thin black shale (Unit 1) grades into normal …

Strict Convexity In Locally Convex Spaces And Fixed Point Theorems In Generalized Hilbert Spaces, Ed Wilburn Huffman

Doctoral Dissertations

"A new definition of strict convexity is introduced for locally convex spaces. Examples are given and several characterizations of strict convexity are established for locally convex spaces whose generating family of semi norms satisfies the parallelogram law.

Some fundamental fixed-point theorems are proved for locally convex spaces whose generating family of semi norms satisfies the parallelogram law. Other fixed-point theorems are proved for strictly convex locally convex spaces which are also F-spaces"-- Abstract, p. ii

Geology Of The Southern Half Of The Stoutland, Missouri Quadrangle, Chester Encell Nichols

Doctoral Dissertations

"The dissertation area lies on the western flank of the Ozark uplift between Lebanon and Camdenton, Missouri. In the northwestern corner of the study area a portion of the Decaturville cryptoexplosive structure is exposed. The dominant structure outside the disturbed zone is a northwest-trending asymmetrical anticline with a subsidiary normal fault dipping southwest on the steeper southwest limb.

The area is mapped in considerable detail in order to describe subtle structural features. To overcome a problem of poor exposures, new key beds are defined which greatly increase structural control. Significant structures recognized as a result are the Dry Auglaize anticline, …

Geology Of The Al-Khums Area Northwestern Libya With Emphasis On The Stratigraphy And Biostratigraphy Of The Al-Khums Formation, Mostafa Juma Salem

Doctoral Dissertations

"The dissertation represents a geologic study of an area bordering the Mediterranean Sea in northwestern Libya. About 1200 km² were mapped and 28 stratigraphic sections were prepared.

The bedrock consists of 16 stratigraphic units of Mesozoic and Cenozoic age having a combined maximum thickness of about 750 meters. The oldest unit exposed, the Abu Shaybah Formation, is a redbed sequence of Triassic and Jurassic age. These beds are unconformably separated from Cretaceous carbonates (Garian Limestone, Ain Tobi Formation, and Gezzar Dolomite). These units in turn are overlain by the Miocene Al-Khums Formation. Younger Quaternary units consist of nearshore marine …

Theoretical And Experimental Investigation Of Oil Recovery By The Electrothermic Technique, Samy Abdel-Hakeem El-Feky

Doctoral Dissertations

"This work investigates the feasibility of increasing oil recovery from petroleum reservoirs by the electrothermic technique. A mathematical model was developed for the prediction of reservoir response to heating by alternating electric current flow through the oil-bearing formations. The mathematical model was programmed in FORTRAN for solution on the IBM 370/168. The model used the finite difference technique to represent the differential equations that describe the system, and the sets of difference equations were solved by the Strongly Implicit Procedure (SIP) and Successive Overrelaxation (SOR).

In order to verify the mathematical model, a set of experiments was conducted to determine …

Extremal Structure Of Convex Sets, J. C. Hankins

Doctoral Dissertations

"Let X be a locally compact closed convex subset of a locally convex Haus Dorff topological linear space E. It is shown that every exposed point, respectively, ray of Xis a strongly exposed point, respectively, ray of X. Also, every extreme point, respectively, ray of Xis a denting point, respectively, ray of X. When the above results are combined one can restate two well-known Krein Milman type theorems due to Klee. There exists a closed convex set that has an extreme point that is neither a denting point nor an exposed point.

In Banach spaces, necessary and sufficient conditions are …

A Blocked Orthogonalization Method For Nonlinear Regression, Daniel C. St. Clair

Doctoral Dissertations

"The blocked orthogonalization algorithm for nonlinear regression developed in this work results from a study of matching problems having certain identifiable characteristics with algorithms which exploit those characteristics. The new algorithm represents an extension of an earlier algorithm by D. S. Grey using a blocked orthogonalization technique proposed by R. E. von Holdt. The result is a generalization of the Grey and the Gauss-Hartley algorithms which maintains the desirable properties of these algorithms while avoiding their more serious limitations. The new algorithm was found to be quite effective for solving problems in which the parameters in the model under consideration …

Simulation Of Nonisothermal Absorber-Reactors For Multicomponent Systems, Robert E. Schwab

Doctoral Dissertations

"There are various models available for calculations involving one transferring component with chemical reaction for isothermal conditions using linear equilibrium data. However, the differential equations for multicomponent mass and energy transfer with chemical reaction have not been developed or implemented. This work demonstrates the development of a reliable model describing multicomponent mass and energy transfer in a continuous two-phase absorber-reactor for Non isothermal conditions and demonstrates the feasibility of solving the differential equations numerically. The numerical solution, using nonlinear equilibrium data, is used to obtain the absorber-reactor column specifications"-- Abstract, p. 2

Applications Of Metrics Over Tikonov Semifields And Fixed Points In Hilbert Spaces, John David Kubicek

Doctoral Dissertations

"For Non expansive mappings on locally convex spaces, sufficient conditions are given for the set of fixed points to be a Non expansive retract. Also, sufficient conditions are given for certain semigroups of asymptotically Non expansive mappings to have a common fixed point.

Several results concerning convergence of the sequence of iterates in metric spaces are generalized to Hausdorff uniform spaces.

In Hilbert spaces, sufficient conditions are given for convergence of a Mann iteration process of strictly quasi pseudo contractive mappings. An example is given to show the process does not, in general, converge for pseudo contractive mappings"-- Abstract, p. …
