Automated Classification Of Eeg Signals Using Component Analysis And Support Vector Machines, Priya Balasubramanian

Masters Theses

Epileptic seizures are characterized by abnormal electrical activity occurring in the brain. EEG records the seizures demonstrating changes in signal morphology. These signal characteristics, however, differ between patients as well as between different seizures in the same patient. Epilepsy is managed with anti-epileptic medications but in some extreme cases surgery might be necessary. Non-invasive surface electrode EEG measurement gives an estimate of the seizure onset but more invasive intra-cranial electrocorticogram (ECoG) are required at times for precise localization of the epileptogenic zone.

The epileptogenic zone can be described as the cortical area targeted for resection to render the patient symptom …

Genetic Health And Population Viability Of Reintroduced American Marten In Michigan, Tamara L. Hillman

Masters Theses

American marten (Martes americana) were extirpated from Michigan’s Lower Peninsula (LP) in 1911, and subsequently from the Upper Peninsula (UP) in 1939 due to habitat loss and unregulated trapping. The species was later reintroduced in the UP in the mid-1950s, and to the LP in the mid-1980s. Previous research has determined the small founding sizes used in the LP reintroductions have resulted in losses of genetic diversity, while research in the UP has produced discordant results concerning the effects of the reintroduction methods on genetic health and population structure. Since past research of marten in the LP, no …

Predictive Modeling Of Floral Species Richness In Michigan Prairie Fen Communities, Nichole R. Mason

Masters Theses

Prairie fens contain high levels of floral biodiversity, including 19 state threatened or endangered plant species, and are classified as rare and vulnerable communities by the Michigan Natural Features Inventory. The objective of this thesis was to develop multiple-regression (MR) models that reliably predict total, native, and invasive floral species richness for use by conservation organizations. Floral biodiversity surveys were conducted in eight southern Michigan prairie fens during the 2012 growing season. Simple linear regressions between fen size and biodiversity were used to optimize sampling strategy and effort (i.e., number of transects and plots per transect) in surveys conducted in …

Effects Of Fatty Acid Structure On Endothelial Cell Expression Of Connexin43, Albert E. Sowers Iii

Masters Theses

The epidemic of obesity-related metabolic and cardiovascular diseases is linked to elevated fatty acids (FA). Epidemiological data argue that trans FA contribute to the development and progression of these disease processes. Previous work suggests the similarity in structure between saturated and trans FA may stimulate inflammation through trans FA interactions with toll-like receptor 4 (TLR4). To evaluate the impact of trans FA on cardiovascular health, the response of endothelial cells to trans FA was evaluated. Specifically, responses to the 18-carbon trans FA elaidic acid (EA) were compared to the same length cis FA oleic acid (OA). Endothelial cells were exposed …

Structural Comparison Of Arctic Plant Communities Across The Landscape And With Experimental Warming In Northern Alaska, Jessica L. Gregory

Masters Theses

Understanding vegetation change is central to forecasting the impacts of climate change. Percent cover, determined from a point frame method, is commonly used to monitor vegetation change. Cover is influenced by canopy structure which may change with the size (growth) or number (density) of individual plants. The overarching objective of this project was to document the relationship between vegetation cover and traits representing plant growth and density and determine if these relationships changed with warming. We used regressions and analysis of covariance to detect which of several traits was most strongly related to cover in vegetation at a wet and …

Genetic Structure Of Yellow Perch Populations In Coastal Areas Of Eastern Lake Michigan, Jessica N. Wesolek

Masters Theses

Genetic population substructure is often overlooked because of discontinuities between management and actual population structure as in the case of yellow perch, an ecologically and economically important indigenous fish species in the Laurentian Great Lakes. A knowledge gaps pertaining to the natural history of yellow perch relates to the biological connectivity between nearshore Lake Michigan and drowned river mouth (DRM) lakes, where it remains unclear whether resident yellow perch from Lake Michigan use DRM lakes for spawning or whether DRM lakes contribute to nearshore yellow perch populations in Lake Michigan. I used DNA fingerprinting (genotyping) to explore biological connectivity between …

Evaluation Of Natural Steelhead Recruitment In The Muskegon River, Michigan, Nicholas C. Albrecht

Masters Theses

The lower Muskegon River is one of the most heavily fished rivers in the state of Michigan and is a valuable component of the multi-billion dollar sport fishery in the Great Lakes. Although significant stocking effort has been invested to maintain and improve the steelhead (Oncorhynchus mykiss) fishery in the Muskegon River, natural recruitment has been severely limited due to high summer water temperatures. The goal of this research project was to evaluate the success of a diffuser system installed in 2008 at Croton Dam to moderate high summer water temperatures in the lower Muskegon River. I estimated natural juvenile …

Rather, most subjects identified reading objectives determined by classroom teachers and developed music interventions to accommodate those objectives. …

Virtual Analysis And Evaluation Of Roundabout Safety And Operational Features, Elisha Jackson Wankogere

Masters Theses

Roundabouts can be a solution to safety concerns present at other types of intersections. Recently in the United States, there has been an increase in conversion of problematic intersections to roundabouts to improve their safety. However, it is difficult to make these roundabouts, especially multi-lane roundabouts, safe to all ranges of users. Roundabout features such as advance warning and signage play an important role in determining driver performance as they navigate the roundabout.

This research is an effort to evaluate new and existing roundabout safety and operational features such as signs and pavement markings and how they influence performance of …

Characterization Of Histidine Decarboxylase In Drosophila Using An Internal Flag Epitope, Maxwell Mianecki

Masters Theses

Histamine is a neurotransmitter in arthropods and is responsible for synaptic transmission in vision, mechanosensation, temperature sensing and sleep cycle in Drosophila. Histamine is synthesized by the enzyme histidine decarboxylase (HDC). While histamine is detectable within tissues using current immunofluorescent labeling techniques, immunological approaches have not been successful for HDC itself, with both direct antibodies and terminal epitope tags determined to be ineffective. In order to avoid loss of the epitope tag through putative N-­‐ and C-­‐terminal proteolytic cleavage, known to occur for HDC in other organisms, an internal epitope tag that does not disrupt enzyme function was utilized. A …

Diffusion Of The Lnternet And Its Effect On Gender Attitudes: A Cross-National Approach, Robert Roznowski

Masters Theses

The rapid diffusion of the Internet worldwide generates discussion about the social implications of the Internet. To explore the effect of Internet diffusion worldwide, this study examines changes in reported gender attitudes since the introduction of the Internet. I propose that the diffusion of the Internet fosters egalitarian changes in gender attitudes. Using cross-national data from forty countries over a time span of nearly twenty years, I successfully implement an alternative analysis technique, the slope-slope model, to examine the relationship between rates of Internet diffusion and changes in gender attitudes in the economic, political, and education domains. Internet diffusion affects …

Neuroprotective Effect Of An Α-7 Nicotinic Acetylcholine Receptor Agonist And A Positive Allosteric Modulator In An In Vitro Model Of Glaucoma, Leah Lyons

Masters Theses

Glaucoma is one of several neurodegenerative diseases of the central nervous system for which a pharmacologic cure is yet to be discovered. In previous studies acetylcholine (ACh) has provided neuroprotection for retinal ganglion cells (RGC) in the mammalian retina under glaucomatous conditions (Wehrwein et al., 2004). More specifically, an α7 nicotinic ACh receptor (nAChR) agonist has demonstrated neuroprotection for RGCs in both in vitro and in vivo models of glaucoma (Iwamoto et al., 2014). In this study, this α7 nAChR agonist was combined with a positive allosteric modulator (PAM) in dissociated adult porcine retinas to evaluate its effect on isolated …

Professional Experiences Of Women Administrators In Student Services, Christy M. Mayo

Masters Theses

The number of women pursuing higher education now outnumbers that of men. However, the number of women in administration and faculty roles does not mirror that of the student population. Instead, women are often found in midlevel and low level positions, especially within student services and student affairs. This thesis is a qualitative study that employs the phenomenological method to explore and examine the professional experiences of seven midlevel administrators in student affairs and student services at GVSU. The constant comparative method of coding was used to analyze the data, identify themes, and articulate assertions. The themes that emerged from …

Contribution Of Foreign Direct Investment To Economic Growth In Bangladesh, Mohammed Abu Rayhan

Masters Theses

Rapid industrialization is essential in Bangladesh to keep pace with its development needs. But the low rate of gross domestic savings and investment as well as low level of technology base hamper the expected industrialization process. Foreign aid and grant had been serving to bridge the gap earlier. As many developing countries are in the process of graduating from being aid-dependent economy into a trading economy, FDI has come to be viewed as a major stimulus to economic growth for these emerging economies. This paper examines the contribution of FDI to economic growth in Bangladesh over the period from 1975 …

The Gross National Happiness infused curriculum aspires to facilitate the holistic education that would address some of the humanistic values we need in this era. In this paper I study the concepts of Gross National Happiness and how the Gross National Happiness infused …

Rhetoric Of Revolt In Thirteenth-Century Castile And England, Jillian M. Bjerke

Masters Theses

This thesis studies the rhetoric of revolt in the thirteenth century by comparing documents and chronicles from the Barons War against Henry III of England (1258-1265) and the revolt of the Castilian nobles against Alfonso X of Castile (1271-1273). By undertaking close readings of these Latin and Castilian texts, I uncover many similar approaches to writing revolt in two roughly contemporary and little-compared rebellions. The first comparison of the two briefs submitted by the rebelling English barons to Louis IX of France for arbitration in 1264 with the purported agreement between the Castilian nobles and Alfonso X presented to Enrique …

The Effects Of Varying Duration Of Reinforcement On Novel Selection-Based Mands Versus Topgraphy-Based Mands, Nicholas S. Acker

Masters Theses

In recent years, researchers have evaluated individuals' preferences for different mand modalities and its effects on the acquisition of novel mands during functional con1munication training (i.e., FCT; e.g., Falcomata, Ringdahl, Christensen, & Boelter, 20 I 0). In many of these studies, the modality of responding that Michael ( 1985) classified as selection-based responding, is preferred by participants (e.g., Falcomata et al., 201 0). Wraikat, Sundberg, and Michael (1991) suggest that topography-based responses may be preferable for the acquisition of complex language. However, selection-based verbal responses may have faster acquisition in learning initial verbal operants (Charlop-Christy, Carpenter, Le, LeBlanc & Kellet, …

Gesture-Sensing Technology For The Bow: A Relevant And Accessible Digital Interface For String Instruments, Zachary Boyt

Masters Theses

Technological advances in powerful, miniaturized electronics have created a growing potential to continue the evolution of string instruments through an accessible digital interface. Although many new types of instruments and controllers have explored this goal, gesture-sensing technology, when paired with the expressive nature of the bow, has provided the most eligible solution towards bridging technology and tradition. Through a selective showcase of technical development, artistic application, and future possibilities, this thesis traces the evolution of gesturesensing bow technology as an accessible digital interface in string instrument performance.

Trajectory Optimization For A Misson To The Trojan Asteroids, Shivaji Senapati Gadsing

Masters Theses

The problem of finding a minimum-fuel trajectory for a mission to the Jovian Trojan asteroids is considered. The problem is formulated as a modified traveling salesman problem. Two different types of algorithms such as an exhaustive search algorithm and a serial rendezvous search algorithm are developed. The General Mission Analysis Tool (GMAT) is employed for finding optimum trajectories with minimal fuel consumption. The selection of a minimum-fuel mission trajectory, and the associated target asteroids, will be a key factor in determining feasibility and scientific value of a Trojan tour and rendezvous mission.

The transfer trajectory followed by a spacecraft between …

The Pagan Pudicitia Of Early Christian Roman Women, Iris Rebecca Petty

Masters Theses

Accessing the everyday experiences of late antique non-elite Roman women in the Latin west is limited by sources and issues of authorship. Interdisciplinary scholarship, however, has opened up new avenues in recent years through which these women’s experiences may be studied. When literary-historical questions are asked of these sources’ authors, audiences, motives and intents, the answers provide insight into the roles women and femininity played in early Christianity. By examining an array of late antique Roman representations of good classical women, a unique continuity is seen in the transition from pagan to Christian Rome. The Latin patristic writers capitalized on …

Failure Of Democratic Consolidation: The Three Year Interlude Of Military Rule (1958-1962) In Burma, Zaw Thein

Masters Theses

Many scholars believe that the period between 1948 when Burma won Independence and 1962 when the military took over the country from the elected civilian government as the parliamentary democracy era. During this era, there was a three-year interlude where the military leaders ruled the country as the Caretaker Government- a euphemism for the three-year military interlude. My argument is that this interlude happened due to the growing strength of the military as an institution and the decline of political parties in Burma. The strength of the military institution was due to the civil war that broke out just after …
