The Design And Analysis Of Drug Combination Experiments, Thomas J. Vidmar

Dissertations

Past literature concerning drug combination studies is reviewed. This literature has both biological and statistical origins. The justification of the logit transformation for dichotomous responses in a linear models framework is made by observing its similarities to models proposed by others. Using the logistic linear model, optimal experimental designs are derived. Methods for obtaining parameter estimates are discussed as are diagnostic techniques for logistic regression. Two new robust techniques for logistic regression are proposed and compared to a robust technique suggested in the literature via Monte Carlo simulation. Finally, estimation of the median effective dose (ED50) and the resulting confidence …

Design And Analysis Of Efficient Algorithms To Solve The Maximum Concurrent Flow Problem, Farhad Shahrokhi

Dissertations

The maximum concurrent flow (MCFP) is a generalized commodity flow problem, where every pair of entities can send and receive flow Ma85 , BM86 , MS86 . We develop efficient labeling algorithms to solve the MCFP. We explore the combinatorial structure of the MCFP and show that the problem of associating costs (distances) to the edges so as to maximize the minimum cost of routing the concurrent flow is the dual of the MCFP. This duality covers max-flow min-cut theorem as a special case. Applications in packet switched networks At81 and cluster analysis Ma86 are discussed.

Determination Of Phenomenological Optical Model Parameters For Neutrons On 208Pb From 4 To 150 Mev, Randy L. Schutt

Masters Theses

Phenomenological o p tic a l model parameters for neutrons incident on ²⁰⁸Pb have been determined for neutron energies from 4 to 150 MeV using the code SNOOPY-8. Neutron total cross sections from 4 to 150 MeV and angular distributions for elastic scattering from 13.5 to 40.0 MeV were utilized. Analyses of total and differential cross sections were performed at a number of energies to determine energy dependent expressions for the real strengths of the central potential, imaginary surface potential, and imaginary volume potential. These energy dependent expressions for V, W_d, and W_S were found to …

A General Design Tool For Computer Directories, Edward J. Peeler

Masters Theses

The primary objective of a directory is to organize information for efficient retrieval. There are many techniques that can be applied to the design of a directory. One particularly useful technique employs the use of inverted files on range attributes. The technique provides an effective directory for a variety of applications and for very large databases. This paper examines the technique and describes the implementation of a general design tool based on these principles.

Horizontal Fragmentation And Allocation In A Distributed Database For Cost Minimization With Reliability And Space Constraints, Elmo Loren Ivey

Masters Theses

In this paper a method for horizontal fragmentation of a relational database is presented. A method is given for calculating the benefit or cost savings obtained by allocating a given fragment to a site, independently for each site.

To obtain optimal benefit each fragment is allocated to all sites where there is a positive benefit. This may result in the allocation of some fragments to multiple sites.

Finally a method is given for removing or reallocating certain fragments from sites with insufficient storage. Also, a method is given for allocating fragments to multiple sites to meet constraints on the required …

An Investigation Into The Numeric Solution Of Linear Recurrence Relations, Dennis Lee Kapenga

Masters Theses

This is an investigation of the use of some techniques from numerical linear algebra in solving linear recurrence relations.

The classic methods of Oliver and Lozier are compared with several alternatives. These alternatives center on using advances in the theory of numerical linear algebra, computer software, and raw computer performance which have been made in the 15 years since the original research into linear recurrence relations was done.

A set of test examples is presented to provide a basis to compare solution methods. This set of examples was selected to allow experiments associated with the Poincare class of recurrence relations. …

Generalized Connectivity In Graphs, Ortrud R. Oellermann

Dissertations

The connectivity of a graph G is the minimum number of vertices in G whose deletion produces a disconnected or trivial graph, while the edge-connectivity of G is the minimum number of edges having this property. In this dissertation several generalizations and variations of these two parameters are introduced and studied.

Chapter I is an overview to the history of connectivity and provides a background for the chapters that follow. In Chapter II major n-connected subgraphs are introduced. Through this concept, the connectivities (of subgraphs) that are most representative in a given graph are studied.

Chapter III is devoted to …

Jacobi Moments In Applied Mathematics With Computer Applications, John A. Kapenga

Dissertations

This work provides solid asymptotic representations, sharp error bounds and stable recurrence methods (both three term and two dimensional) for the Jacobi moments. These moments are currently used in several areas of numerical analysis (numerical integration, integral equations and boundary value problems).

A powerful representation theorem, due to H. Gingold, which uses the Jacobi moments is extended and analyzed. Applications of this theorem to multi-turning point problems and several other areas are given.

For a number of important problems in mathematical physics it is not possible to prove that the currently employed methods of solution converge, or are valid in …

Hydrodynamic Character Of The Dundee Limestone In The Central Michigan Basin, Ann Carol Little

Masters Theses

The Middle Devonian Dundee Limestone underlies most of the Lower Peninsula of Michigan. A potentiometric surface constructed of the formation, utilizing pressure data was compared to local and regional structure, permeability trends, specific gravity of the brines, oil accumulations, and surficial topography.

The data were distributed mainly in the central basin area, with information becoming more sparse around the basin margins. This created difficulties in the determination of the extent of control imparted by each of the factors, in flow direction. Surficial topography, on a regional scale, is likely the most influential of the controls, with the Dundee Limestone brines …

A Structural Investigation Of A Basement-Involved Thrust System In Southern Sphinx Mountain Quadrangle (Madison Range) Southwestern Montana, Jeffrey Scott Brown

Masters Theses

The Madison Range is the eastern limb of the Laramide Rocky Mountain foreland Madison-Gravelly Arch. The main segment of the Madison thrust system in the map area is the basement-involved Scarface thrust which dips westward, trends north-northwest, and places Archean rocks onto an overturned footwall of Cambrian through Cretaceous rocks. Foliation of Archean rocks in the footwall is folded with overlying sedimentary rocks.

The Shedhorn Mountain thrust splays from the Scarface thrust. It is exposed north and south of the Shedhorn Mountain anticline, but is blind beneath it. The Taylor fault, an east-dipping back thrust, is inferred to be associated …

A Study Of Classical Elastic Scattering For Heavy-Ion Nuclear Reactions, John C. Orrison

Masters Theses

Numerical computer programs were developed to calculate the classical elastic scattering orbits, deflection functions and differential scattering cross-sections for a heavy-ion nuclear reaction model.

Critical points of the deflection functions and differential scattering cross-sections were examined.

Semiclassical modifications were developed for future study to account for the phase relation between independent orbits that lead to the same scattering direction.

Stratigraphic And Sedimentologic Analysis Of The Middle Devonian Filer Sandstone, John Charles Rodwan

Masters Theses

The Filer Sandstone, a multistory assemblage o£ lenticular sand bodies, is a member of the Middle Devonian Amherstburg Formation of the Detroit River Group in the subsurface of the western and central portion of the Michigan Basin. It is distinguished from the reworked eolian and nearshore marine sand facies of the underlying Sylvania Sandstone by recognition of its barrier island facies relationships and stratigraphic position within enclosing carbonates unique to the Amherstburg Formation. Lithologically, the Filer ranges from a fine-grained, carbonate-cemented, supermature quartzarenite at its upper shoreface facies, to a texturally-inverted sandy carbonate at its lagoonal facies. Facies distribution was …

Reactive Counterion Surfactant Catalysis Of Hydroxamic Acid Hydrolysis With Perfluorooctanoic Acid, Mohamed El-Sayed Ayoub

Masters Theses

A micellar effect upon the rate of hydrolysis of hydroxamic acids in aqueous perfluorooctanoic acid has been demonstrated for hydroxamic acids with chain lengths of six , eight, and ten carbons. In this system the counterion, hydrogenion, is a catalyst. Typical rate constant-surfactant concentration profiles for micellar catalysis were obtained. The results for these hydrolyses are consistent with the pseudo-phase model for micellar effects.

In addition the Arrhenius activation energies were determined for the reaction of octanohydroxamic acid at surfactant concentrations above and below the critical micelle concentration of the surfactant. The activation energy is lower for reaction in the …

Further Studies On Purification Of A Mannitol Binding Protein: Use Of Ph Gradients For Elution From Cation Exchange Resin, Kristyne Ann Baumgarten

Masters Theses

Studies on the purification of a mannitol binding protein (MBP) from Pseudomonas aeruginosa PAO were performed. Utilizing the alkaline isoelectric point (pi 8.3) of MBP, pH gradients were used to elute MBP from carboxymethylcellulose cation exchange resins. Purification of MBP was monitored by sodium dodecyl sulfate-polyacrylam ide gel electrophoresis (SDS-PAGE). Only one protein band was seen on SDS-PAGE from MBP fractions elutedat pH 7-8 and 8 .2. Although pH gradients appear to give good purification from cation exchange resins, these procedures lead to loss of MBP activity.

Facies Development And Porosity Relationships In The Dundee Limestone Of Gladwin County, Michigan, Eric Lee Montgomery

Masters Theses

The Devonian of the Michigan Basin was a time of transgressive seas and extensive carbonate deposition including coral and stromatoporoid buildups. Deposited during the Middle Devonian, the Dundee Limestone represents deposition in subtidal, intertidal, and restricted environments. The Buckeye Oil Field, located in south-central Gladwin County, is a combined stratigraphic and structural carbonate trap which produces from a series of intertonguing patch reefs, fringing sand bodies, and "intertidal island" fenestral zones. The major reef building organisms include stromatoporoids, corals, calcareous algae, brachiopods, and crinoids, with the stromatoporoids providing the major framework. The patch reef facies is composed of massive stromatoporoid …

A Query Optimization Method For Use In A Generalized Database, Caroline D. Mautz

Masters Theses

Currently proposed methods for retrieval of records from a generalized file organization are not optimal, causing more I\0 retrievals than are necessary. This paper proposes another technique that has near optimal results and has a polynomial order of complexity.

The technique takes as input a query in disjunctive form, sorts the keys in the query in ascending order according to the number of records associated with them, then using a table much like a prime implicant table, systematically searches for a complete cover of the query conjuncts with a minimum total number of records associated with the keys that are …

The Provenance Of The Jacobsville Formation Of The Upper Peninsula Of Michigan Through A Petrographic Study, David Walter Lindsay

Masters Theses

The Upper Keweenawan Jacobsville Formation source areas were mixed source terranes with dominant terrane types changing regionally in relative abundances of sediment contribution. Dominant source terranes were older sediments, including a weathered soil zone, Upper Keweenawan Freda Sandstone and other recycled sandstones; plutonic Precambrian basement rocks;. Middle Keweenawan Portage Lake Volcanics; and the chlorite to staurolite grade metamorphic rocks and iron ranges of Michigan’s upper peninsula.

Depositional environments of the formation's four facies types range from fluvial to deltaic/lacustrine. Sediments were in transport for a short distance, resulting in grain freshness and angularity, moderate sorting and preservation of unstable sediments. …

The Effects Of Acid Precipitation On Two Lakes In Southwestern Michigan, Fardin Olyaei

Dissertations

The purpose of this study was to investigate the extent to which acid precipitation contributes acidity and heavy metals to lake environments. Asylum and Bonnie Castle Lakes, both located in the western portion of Kalamazoo County, served as the study sites. Precipitation samples were also taken at a site close to both lakes. Using the Hach Colorimeter, a preliminary study was undertaken to determine concentrations of the major cations (H('+), NH(,4)('+), K('+) and Ca('2+)), and major anions (NO(,3)('-), SO(,4)('2-), and PO(,4)('3-)). The main study dealt with the metal concentrations (Mn, Fe, Cu, Zn, and Pb) in rain/snow water, lakewaters, sediment, …

An Evaluation Of The Effectiveness Of Bentonite As A Soil Additive For The Cover Material On The Kl Avenue Sanitary Landfill, Kalamazoo, Michigan, Neal J. Carey

Masters Theses

A principle objective of using bentonite as a soil additive is to reduce the permeability of a cover material, thus, inhibiting the infiltration of surface waters at landfill sites.

Twenty-two cores of the KL landfill were taken to obtain in-situ soil columns for testing. Coefficients of permeability were calculated for each soil column using the falling-head permeameter. Mechanical and hydrometer analyses were used for the grain size analysis. The methylene-blue test was employed to determine the actual percentages of bentonite present in each soil column. X-ray diffraction work was done on the clay fraction of each soil column to verify …

Petrography, Diagenetic History, And Development Of Porosity In The Richfield Member Of The Lower Middle Devonian Lucas Formation, Northeast Isabella County, Central Michigan Basin, Kevin James Sullivan

Masters Theses

The Richfield Member of the lower Middle Devonian Lucas Formation is represented in the subsurface of northeast Isabella County, Michigan as a 180-foot-thick sequence of Interbedded limestone, dolomite and anhydrite. Richfield lithofacies within the study area reflect deposition in a complex patchwork mosaic of evaporative supratidal, in tertid al, shoal, and subtidal environments.

The present variations in Richfield porosities were caused almost entirely by post-depositlonal diagenetic changes. The carbonate units have undergone pervasive dolomltlzation of mud matrix, leaching of allochems, and extensive anhydrite void -fillin g . The best porosity developments are associated with partial to complete dolomitizatlon of the …

Syntactic Representation And Analysis Of The Cognitive Structures Underlying Ritual Acts, Robert G. Hardin

Masters Theses

A formal grammar was proposed by Lawson and McCauley (1980) to model the cognitive structures underlying an informant's representation of religious ritual acts. This study classifies the language generated by that grammar as context-sensitive, presents an LR(1) parser for the language, and specifies a computer program to implement that model. The system functions as an Intelligent assistant using techniques involving rule-based systems, non-monotonic logic, and multiple levels of abstraction. Knowledge is represented in a parse tree, rules stored as patterns, and the inference engine uses a pattern matcher. The consequences of an act change over time and can change previous …

Simultaneous Knudsen- And Torsion-Effusion Measurements Of The Vapor Pressures Of Triphenyl Aluminum And Triphenyl Boron, Steven Wayne Govorchin

Masters Theses

The sublimation pressures of triphenyl aluminum and triphenyl boron have been determined from simultaneous measurements of the rate of mass effusion and torsional recoil. For triphenyl aluminum the measured vapor presures are expressed by the equations:

logio (P_k/P°) = (12.76 ± 1.25) - (8214 ± 572) (K/T)

logio (P_t/p °) = (12.83 ± 1.34) - (8206 ± 615) (K/T)

where P_k and P_t are the pressures measured by the Knudsen-effusion and torsional-recoil techniques, respectively, and p° = 101.325 kP_a. For triphenyl boron the measured vapor pressures are expressed by the equations:

log …

Medium Modified Proton Densities Deduced From Electron Scattering Experiments, Steven Paul Deryke

Masters Theses

Recently two fundamental problems in nuclear physics have been resolved by applying the concept of nucleon size increases over that of free nucleons. These successes have encouraged the use of medium-modified proton densities to explain the differences between Hartree-Fock calculations and experimental charge densities. These differences constituted a long standing problem in nuclear physics.

The covariant soliton model of density dependent nucleon form factors was employed to explain these differences. This model predicts a non-linear relationship between point proton densities and charge densities. This work was able to provide a self-consistent proton density for ²⁰⁸Pb by inverting this relationship. …
