Cambrian-Early Ordovician Sequence Stratigraphy And Mount Simon Sandstone Petrology-Michigan Basin, Jeffrey T. Cottingham

Masters Theses

Michigan subsurface correlation is complicated in the Cambrian-Early Ordovician section due to limited availability of rock data. Core and cuttings examination demonstrate that similar stratigraphic sequences exist between the Michigan Basin and surrounding regions. Lithofacies in Wisconsin outcrop are similar to their basinal counterparts, and are correlated on the basis of sediment types, sedimentary structures, and the sequence stratigraphic concept.

The Mount Simon Sandstone in Michigan correlates with that observed in Illinois, Wisconsin, and Iowa. Isopach data throughout the Midwest indicate a single depocenter in Northeastern Illinois. Sedimentary structures and lithology indicate a subtidal environment that may be a progradational …

Reservoir Geology Of The Dundee Limestone, West Branch Field, Michigan, Brendan Ciaran Curran

Masters Theses

West Branch field is a low-relief, NW-SE-trending anticline near the center o f the Michigan basin. Since 1934, the Dundee Limestone (Middle Devonian) has produced over 12 million barrels of oil from this field. From core studies, six depositional facies types were recognized in the Dundee. These are dominated by bioclastic carbonate sand facies deposited in normal-marine shelf settings. Although burial cements have occluded some porosity, carbonate sand facies have retained significant primary interparticle porosity and are the most important reservoir rocks. Micritic facies with restricted faunal assemblages are present at the top of the Dundee. The top 10 to …

A Hydrogeological And Hydrogeochemical Investigation Of Groundwater At A Landfill For Sludge From The Kalamazoo Wastewater Treatment Plant, Richard Howard Christensen

Masters Theses

Major cations and anions were analyzed to determine groundwater chemistry at a site used for the disposal of municipal sludge in the late 1960s and contaminated Portage Creek sedimem dredged in the late 1970s. The disposal site consists of five unlined basins constructed over 50 to 100 feet of stratified sand and gravel outwash underlain by silt and clay. Groundwater in the outwash is unconfined and flows from east to west. A groundwater divide in the center of the site produces local divergent flow to the northwest and southwest. Measurements of chemical constituents indicate that three factors influence groundwater chemistry …

Spatial And Temporal Variations Of Synthetic Organic Compounds In The Contaminant Plume Emanating From The Kl Landfill, Lynn Diane Broede

Masters Theses

Thirty-one synthetic organic compounds have been detected in samples collected from the KL Landfill contaminant plume from March, 1980 to March, 1986. Two groups of organic compounds have been delineated based on their occurrence, concentrations, and persistence throughout the 7-year monitoring period.

Changes in plume geometry and concentration have been studied relative to time, and concentration variations have been related to selected inorganic plume parameters, distance from the landfill, and precipitation. The spatial and temporal distribution of the organic compounds are attributed to biodegradation, three biotransformation sequences, physical properties of the organics and other factors. Three abbreviated anaerobic biotransformation sequences …

Intracellular Degradation Of Ribosomes In A Mesophilic And A Thermophilic Species Of Bacillus, Joe William Davis

Dissertations

The rates of intracellular degradation of ribosomal proteins were compared in a mesophilic and a thermophilic species of Bacillus. Cells were grown under various incubation conditions in the presence of a 14^C-protein hydrolysate m order to label the ribosomes. Rates of ribosome degradation were evaluated in terms of changes in the specific activity of in vivo ribosomes as a function of incubation time. The results indicated that, under most conditions, ribosomes were degraded (in vivo) at similar rates in both the mesophile and the thermophile. In some studies, ribosome degradation rates were slightly faster for the thermophile than for the …

Ctran: Transforming Scientific Fortran Programs To Unix Based Computing Environments, Qi Chen

Masters Theses

FORTRAN is one of the most popular scientific programming languages. The efficiency, rich libraries, and popularity of FORTRAN support its continued use as a programming language for scientific computing in the near future. However, in current multiprocessor UNIX environments, C is often better supported. The desire to use existing FORTRAN subroutines within such a C environment leads to several options. In this thesis, we introduce a "modern" scientific programming language called CTRAN for this purpose.

We begin with a brief review of the history of scientific programming languages. An introduction of CTRAN is given in Chapter HI. In Chapter IV, …

Hydrogeology And Hydrogeochemistry Of The Tekonsha Moraine And Adjacent Interlobate Deposits In Charleston Township, Kalamazoo County, Michigan, Victor V. Melbardis

Masters Theses

Hydrogeochemical analyses and hydrogeologic interpretations provide the basis for an understanding of local ground-water flow, in a 12 square mile study area, transected by the Tekonsha Moraine and bound by glaciofluvial deposits. Glacial tills separate an upper and lower aquifer system throughout most of the area.

Degraded and tritiated ground water is present in the lower aquifer system. A negative correlation (-0.62) between tritium concentrations and depth is statistically significant (.04). In this local system, hydrochemical trends are characterized by decreases in sulfate percentages and increases in bicarbonate in the direction of ground-water flow. Statistical evaluation of the hydrochemical data …

The Enumeration Of Graph Imbeddings, Robert G. Rieper

Dissertations

Graphs can be drawn on surfaces. Here, graphs may have multiple edges or loops (pseudographs), the surfaces are closed orientable 2-manifolds (sphere, torus, etc.) and their generalizations (pseudosurfaces and generalized pseudosurfaces), and the drawings are 2-cell imbeddings. For quite some time it has been known that a connected graph has $\rm \Pi(degree(\upsilon)-1)$! 2-cell imbeddings on surfaces. More detailed information about these imbeddings has been wanting. In addition, many of the imbeddings counted above 'look the same' when all vertex and edge labels are removed. The resulting unlabeled imbeddings are fewer in number and more difficult to enumerate than their labeled …

Enumerating The Orientable 2-Cell Imbeddings Of Complete N-Partite Graphs, Bruce P. Mull

Dissertations

This dissertation develops formulas for the number of congruence classes of maps of complete, complete bi-partite, complete tripartite, and complete n-partite graphs; these congruence classes correspond to unlabeled imbeddings. The method employed for the enumeration is an extension of that used by Mull, Rieper, and White in 1988. We let the automorphism group act on the set of rotations and use Burnside's Lemma to count orbits for these rotations. Compatible permutations are introduced to determine those automorphisms actually contributing to the number of orbits.

The complete n-partite formula is shown to generalize those of the other three families of graphs. …

On Distance In Graphs And Digraphs, Songlin Tian

Dissertations

One of the most basic concepts associated with a graph is distance. In this dissertation some new definitions of distance in graphs and digraphs are introduced. One principle goal is to extend certain known results involving the standard distance function on graphs to the field of digraphs with an appropriate concept of distance. Several parameters as well as subgraphs and subdigraphs defined in terms of distance are investigated.

Chapter I gives a brief overview of the history of distance and generalized distance in graphs. By presenting a listing of major results in this area, it provides a background for the …

Simulation Of Bromide Transport In A Layered Aquifer Using Two-Dimensional And Three-Dimensional Computer Models, Kathleen Michelle Hewitt

Masters Theses

Simulation of a two-well tracer test at a site near Mobile, Alabama was performed and compared with the experimental breakthrough curve. The models used to simulate the test results were the three-dimensional USGS code HST3D and the two-dimensional USGS code MOC. The results of the three-dimensional model were also compared with the results of the two-dimensional model.

The three-dimensional model HST3D predicted the measured breakthrough curve accurately with the exception of early arrival times of the tracer in the withdrawal well. The two-dimensional model MOC did not accurately predict the bromide concentration in the withdrawal well during the two-well test. …

Sql/Ds, Ingres And Indexes: A Comparative Study Of The Use Of Indexes In Two Database Systems, Karen L. Bourn

Masters Theses

Many people in data processing desire to know more about the performance of relational databases. Little information about performance exists in the product or public literature. The purpose of this study is to compare one aspect of the performance of relational databases. The aspect explored is the indexing of tables in a relational database. This paper compares the use of indexing in two relational databases, SQL/DS (Ver. 2, Rel. 1) and INGRES (Rel. 5.0/0.6). Queries were created and executed on tables in both databases, first without an index and then with several different indexes.

The findings in this study show …

Development Of A Neural Net Model For The Assignment Problem, Philip Paul Moss

Masters Theses

This thesis traces the development of a neural net model which will solve the assignment problem. In addition, the neural net model was compared for optimal performance with four other algorithms: two greedy methods and two well-known solutions, Vogel's Approximation Method (VAM) and the Hungarian method. Assignments were made to randomly generated problems using each method and the results were compared.

The findings from this testing indicated that: (a) the assignments selected by the neural net model were closer to optimal than the two greedy methods and VAM, and (b) the assignments selected by the neural net were not optimal. …

The Mapping Of A Colored Petri Net Model To An Ops5 Rule-Based Production System, Sally S. Lockwitz

Masters Theses

This paper defines a method by which the colored petri net model of a concurrent system may be mapped to an equivalent rule-based production system. The mapping method defined is an intuitive process which results in a production system that clearly represents the petri net model.

In order to demonstrate the effectiveness and correctness of this method, the colored petri net representation of a part of a flexible manufacturing system of the Renault Car Company is mapped to an equivalent Sierra OPS5 rule-based production system.

An overview of petri nets and rule-based production systems is presented, along with a brief …
