Recent Seismicity And Regional Extension Aithin Southwestern Montana, Usa, Jessica Szkody

Masters Theses

Southwestern Montana has experienced several large damaging earthquakes over the last 100 years, but many minor ones that unveil the nature of the intraplate seismicity. The region in this study is part of two distinct Late Cretaceous tectonic provinces, the Rocky Mountain Foreland Basement (RMFB) and the Cordilleran Fold and Thrust Belt (CFTB). Relationships between the two provinces and their faults show that the focal mechanisms are different. Deep focal mechanisms (between 8 and 10 km) within the RMFB can be placed on a specific fault, with many smaller events falling within the hanging wall. The hypocenters within the hanging …

The Foundation Of Cistercian Monasteries In France 1098-1789: An Historical Gis Evaluation, Jon Eric Klingenberg Rasmussen

Masters Theses

Historical geography focuses upon those relationships which have shaped the evolution of place and landscape over time. One fundamental approach used to achieve this objective is the set of theories associated with spatial diffusion. This includes the spatial and chronological paths, the periodicities and rates of spread, as well as the identification of areas of void or avoidance. An emerging trend in historical geography is the use of Geographic Information Systems (GIS). A GIS provides the researcher with the necessary tools to re-evaluate and challenge long-standing interpretations of any given event, historical or otherwise, as well as develop new insights …

A Teleological Exploration Of The Plausibility Of Moral Knowledge, Kevin Lebel King Jr.

Masters Theses

Natural selection seems to offer a compelling case for the development of evaluative judgments independent of evaluative facts. If such a case can be made, then how do moral judgments correlate to moral facts? It seems that there would be no tight connection from judgments to truth and moral judgments would be unwarranted. Gilbert Harman realized the implications of a probable non-moral genealogy. Richard Joyce goes on to provide a probable non-moral genealogy that would epistemically undermine moral judgments as Harman thought. Joyce argues that in a naturalistic world natural selection can account for moral judgments, but that the truth …

Anomalous Thermal Indicators From Authigenic Minerals In Upper Paleozoic Strata Of The Michigan Basin, Kyle Cox

Masters Theses

Indications of anomalous paleo-temperatures exist in strata of the Michigan basin, USA. The thermal history of the basin was investigated through identification and analysis of authigenic components in two Upper Paleozoic strata, the Devonian Dundee Formation and Mississippian Marshall Sandstone. Formation conditions for diagenetic phases in both units were estimated through a variety of means and compared to conditions expected for a simple burial model. Authigenic clays identified in the Marshall via X-ray diffraction are expected to have formed at temperatures above what would have been produced by burial alone. Stable isotope and fluid inclusion analysis indicate the same for …

Performance Analysis Of Distance Relay On Shunt/Series Facts-Compensated Transmission Line, Ahmed Kareem Lafta Al-Behadili

Masters Theses

Flexible Alternating Current Transmission Systems (FACTS) are increasingly being used to enhance the efficiency and reliability of power system networks. FACTS devices can influence the performance of existing protective system components (specifically distance relays) due to the fact that FACTS change power system quantities such as line impedances, voltages, and currents. Distance relay may mal-operate when FACTS devices are connected since they cause some of the tripping characteristics to change. This thesis investigates the impact on distance relay performance due to compensations using two types of FACTS controllers: Static Synchronous Compensator (STATCOM) and Static Synchronous Series Compensator (SSSC). Analytical study …

Thermal History Of The Michigan Basin: Results From Thermal Maturation Data And Geodynamic Modelling, Kirk A. Wagenvelt

Masters Theses

Thermal cooling, crustal convection, high temperature fluid advection, and 1.0 Km of eroded overburden are required to explain thermal maturation observations in the Michigan Basin. Observed tectonic subsidence in central Michigan follows an exponential decay indicative of thermal cooling following an anomalous heating event. Crustal convection is responsible for episodes of rapid subsidence coincident with the late Paleozoic Appalachian orogeny. Fluid advection through dilated faults reactivated by the Alleghanian orogeny brought hot fluids (as much as 255⁰ C) to the surface and impacted thermal maturation of organic matter in sediments. Models require 1.0 Km of eroded overburden to model thermal …

Masters Theses

Adelbert Ames, a Civil War general before he was thirty years old, exemplified the characteristics and embodied the elements of the essential solider. He, and other mid-level commanders like him, provided pivotal and instrumental leadership that helped the Union win the war. In short, Ames was one of the most talented and highly regarded young officers in the Union Army, and boasts perhaps the finest record of any "boy general" who fought for the North during the American Civil War. Ames was not just an average soldier or a mere participant in a large volunteer army. He was not a …

The Many Paths Of Cyberspace: William Gibson's The Sprawl As Prototype For Structural, Thematic, And Narrative Multilinearity In New Media, Erik Marsh

Masters Theses

William Gibson’s Sprawl trilogy helped set a new direction for science fiction, but his work is also a valuable tool for examining changes in the approach both readers and writers began to take to approaching literature as the text medium began its rapid evolution with the introduction of electronic hypertext. In this examination of Gibson’s fiction, a pattern of multilinear truth emerges, showing how Western culture began to fully embrace Postmodern approaches to truth claims as a default, how even a pre-electronic text can exhibit hypertext-like aspects, and how this shift in interpretive response to literature is important for Christians …

Neoplastic Therapy : On Violence And Aesthetics, Mengyu Chen

Masters Theses

The goal of this thesis is to create a new theoretical framework to examine and understand the meaning of an art object and its relational social existence. This thesis serves as a critique on contemporary media culture and hierarchical social oppression. At the same time, it adopts a pseudoscientific way to introduce notions of art’s autonomy and its opposition to social functionality. By merging political theories on individualism, capitalism, and metaphysics with foundational structures of art creation, I am attempting to construct a new system of thinking that challenges traditional ways of understanding mediums, functions and the viewer’s relationship with …

Think Again: The Decision Making Process In King Lear And Jane Smiley's A Thousand Acres, Elizabeth Burgess

Masters Theses

This thesis is a feminist reading of Shakespeare‟s King Lear and Jane Smiley‟s Pulitzer Prize winning novel A Thousand Acres that applies psychological insights into human behavior to explain economic decision-making. Many of the traditional readings of King Lear, including the works of critics A. C. Bradley, Maynard Mack and Stephen Greenblatt, approach the play by accepting the patriarchal view of Lear as the rightful ruler, while Goneril and Regan are wicked for taking the kingdom from their father. Smiley‟s A Thousand Acres, however, approaches the text from what she imagines Goneril‟s perspective to be and includes the …

Hybrid Fuzzy-Pid Controller For Buck-Boost Converter In Solar Energy-Battery Systems, Karime Farhood Hussein

A Simpler Route To Building Photochromic Cinnamaldehyde Semicarbazones, Byron R. Ebbert

Masters Theses

Photochromic semicarbazones are an interesting group of compounds that show potential in a broad range of applications, including as a more environmentally friendly replacement for photochromic metal complex compounds. Previous work has shown the feasibility to synthesize photochromic cinnamaldehyde semicarbazones (CSCs) from a benzaldehyde and a protected acetaldehyde Wittig reagent. A new, quicker, and cheaper approach to constructing these CSCs from crotonaldehyde was explored in this research. A three reaction sequence would convert crotonaldehyde to a CSC; first, an allylic bromination of the semicarbazone with N-bromosuccinimide (NBS); second, an Arbuzov reaction to prepare the semicarbazone phosphonate; and finally a condensation …

The Impact Of Homework On The Achievement Of Students With Varying Science Aptitudes In High School Physics, Matthew Deets

Masters Theses

When students in a high school physics class are separated into high, middle, and low aptitude levels, it was discovered that they do not all show the same benefits from completing homework assignments. The focus of this study was to analyze the relationship between the amount of homework that students complete and their performance on quizzes and exams. The results indicate that middle and high aptitude students benefit from completing greater amounts of homework, however, low aptitude students show no improvement by completing a greater number of problems.
