Understanding Individuals’ Perceptions Of Oak Wilt And Its Implications For Invasive Species Management, Matthew Morrissey

Masters Theses

Oak wilt, a thought-to-be exotic, invasive fungal disease preys upon oak tree species (Quercus sp.) and has begun to cause die-off in oak stands throughout the state of Michigan, with potential for increased cases and subsequent death. Despite efforts to treat the disease, there is no guaranteed treatment for already-infected oak trees. The best option is to control the infection and prevent its spread, by methods such as disconnection of root systems, removal of infected trees, and informed pruning. Given that humans play a role in oak wilt’s artificial spread, it is imperative that the public understands their …

Modeling And Simulation With Optimal Gear Ratio For A Forward-Looking, Velocity-Driven, Power-Split Hybrid Electric Vehicle, Sonal Babasaheb Kanap

Masters Theses

Increases in vehicle demand and fossil fuel consumption are major contributors to environmental problems, such as air pollution and climate change. This has led to research on alternative, energy-efficient vehicle technologies. Automobile users are now preferring comfortable vehicles with minimal fuel consumption and with more efficient engines. Hybrid cars are becoming common because of their advantage of running cleaner and with better gas mileage. A hybrid car runs on the power of both an electric motor and a gasoline engine. This mechanism helps cut fuel consumption and conserve energy. An additional advantage is a regenerative braking system that helps recharge …

Habitat Suitability Of The Mountain Pine Beetle In Alberta, Canada Under Future Climate Scenarios, Nathalie Woloszyn

Masters Theses

Mountain pine beetle (Dendroctonus ponderosae Hopkins) is the most destructive insect currently devastating North American forests (Safranyik & Carroll, 2006). Native to western North America, the mountain pine beetle has recently expanded beyond its historic range, into the novel territory of Alberta, Canada. Since its arrival in the mid-2000s, the mountain pine beetle has diffused eastward at an average rate of 80km/year (Cooke & Carroll, 2017). Poised at the doorstep of the boreal forest, current concern anticipates the potential diffusion of the mountain pine beetle to eastern North America.

Mal_Functions For String Quartet And Live Electronics, Elliott Andrew Lupp

Masters Theses

Mal_Functions is a four-movement work for string quartet and live electronic that takes as its subject the timbrally rich and expansive acoustic capabilities of a string quartet and twists, warps, and expands upon them with the addition of the live electronic processing. The addition of electronics acts as only an extension of the performer, and therefore, appears to be generated by the performers themselves - as opposed to the computer. The overall goal of this piece is to take a well-established object of the musical past (the string quartet) and add to it something from the present day (live electronic …

Training Set Density Estimation For Trajectory Predictions Using Artificial Neural Networks, Zachary Reinke

Masters Theses

Demand on earth orbiting surveillance systems in increasing as more equipment is put into orbit. These systems rely on predictive techniques to periodically track objects. The demand on these systems may be reduced if object trajectory data to develop scalable training sets used for training artificial neural networks (ANNs) to predict trajectories of a dynamic system. These methods use multi-variable statistics to analyze data energy content to provide the ANN with low density, feature-rich, training data. The developed techniques have been shown to increase ANN prediction accuracy while reducing the size of the training set when applied to a linear …

Utilizing Geophysical Attributes To Investigate The Architecture Of A Pinnacle Reef Complex, Michigan Basin, Usa, Austin M. Johnson

Masters Theses

The Silurian Niagaran Pinnacle Reefs of the Michigan Basin retain their relevance after primary recovery of hydrocarbons and are excellent candidates for carbon dioxide sequestration, natural gas storage, and enhanced oil recovery. Due to the nature of carbonate rocks, these reef complexes are heterogeneous and lateral interpolation between observations in wells, is ambiguous. Ambiguity has led to large uncertainty and disagreement regarding reef architectures and their internal facies distributions. Previous models of these reef complexes have relied almost entirely on well logs and conventional core. This study focused on integrating 3D seismic reflection data to reduce uncertainty when delineating the …

Wonder Women In A Superman World: Exploring The Memorable Messages And Communicative Approaches Women Utilize When Navigating The Leader-Member Relationship, Christine M. Packard

Masters Theses

Communication scholars continue to affirm the importance of organizational members to develop strong relational ties with those in their workgroup. This research focuses on women and considers relationship development via the memorable messages women receive prior to their entrance into the workplace. Further participants’ critical incidents or pivotal moments with managers are examined to consider how those experiences shape how women navigate workplace challenges and the leader-member relationship. Fifteen in-depth qualitative interviews resulted in the emergence of four themes: preparatory frameworks, the perception of trust, autonomy, and competence, adaptive communicative approaches, and socialized expectations. These findings call to attention the …

Depositional Facies And Sequence Stratigraphic Model For The Silurian Reefs, Michigan Basin, Usa, Zaid N. Nadhim

Masters Theses

Depositional models for the Silurian reefs in the Michigan Basin suggest that internal facies are either (i) randomly distributed within a symmetrical reef structure, or (ii) highly asymmetrical and strongly controlled by paleo-wind direction. To further test the applicability of these models, internal facies distributions were mapped using high-resolution core and log data in two sets of Silurian reefs. The results suggest that the relationship between reef geometry, facies distribution and proposed paleo-wind direction is more inconsistent than recently proposed. More specifically, facies descriptions from the Silurian reefs suggest the following. First, overall reef geometry and facies distributions are not …

The Use Of High And Medium Resolution Imagery To Detect Agricultural Land Cover In Chinese Cities: A Case Study Of Nanjing 2000 To 2015, Erik Breidinger

Masters Theses

According to McGee and Ginsburg’s desakota hypothesis, rapidly growing Asian cities differ from large Western cities in their land cover/land use (LC/LU) as they retain a significant portion of agricultural land and labor despite rapid urbanization. However, significant amounts of agricultural production within desakotas takes place in plastic greenhouses, causing a unique problem when calculating LC/LU estimates via traditional remote sensing techniques. While greenhouses appear equivalent to developed land spectrally, their purpose is entirely agricultural. This study provides an improved method of calculating greenhouse land-cover as agricultural land-use using Jiangning District in the city of Nanjing as the study area …

Thermal Maturation Modeling Of The Michigan Basin, Jack H. Hybza

Masters Theses

Given present day heat flow and burial depths in the Michigan Basin, hydrocarbons should be immature. However, oil and gas are abundant within the basin. Our hypothesis is that thermal maturation distributions in the Michigan Basin can be explained by variations in proximity to the Midcontinent Rift (MCR) system, thermal cooling, crustal convection, high temperature fluid advection, and eroded overburden.

For each of the seven wells in this study, a geohistory plot is coupled with a range of geodynamic models to calculate the thermal and maturation histories of each sediment unit within the well. Backstripping was used to generate basement …

Police-Community Collaboration In An Upper Midwest City, Samuel Imbody

Masters Theses

Recent clashes between law enforcement and civilians have brought the issue of police-community relations to the forefront of many political discourses. While community policing has achieved a degree of success in alleviating these problems, many of the issues raised by the seminal Kerner Commission in 1967 remain today. This phenomenological case study represents a contemporary look at a city named “Heartland,” which has received accolades from numerous organizations for its community policing efforts. The primary source of data were in-depth interviews with police officers, and members of community organizations in the city of Heartland, analyzing how these two parties collaborate …

Model Predictive Control Synthesis For The Innovative Control Effector Tailless Fighter Aircraft, Christopher Proctor

Masters Theses

A nonlinear model predictive control law was developed for the Lockheed Martin Innovative Control Effector tailless fighter aircraft to track way points. In general, aircraft are described by nonlinear dynamics that are dependent on the regime of flight. Additionally strict requirements on state and actuator constraints are common to all aircraft. Tailless aircraft are usually overdetermined systems, meaning solutions to control problems are not unique, and the system is non-affine. The proposed nonlinear control law considers those constraints during run-time, and solves the nonlinear control problem for a range of points within different flight regimes. The control law was developed …

An Examination Of Flintlock Components At Fort St. Joseph (20be23), Niles, Michigan, Kevin Paul Jones

Masters Theses

The purpose of this study is to identify the age, country and place of origin, function (e.g. fusil, pistol), and intended use (e.g. military, trade gun) of flintlock components recovered from Fort St. Joseph (20BE23), an eighteenth-century French mission-garrison-trading post in southwest Michigan. Flintlock muskets were a vital technology in New France throughout the fur trade era, both in their roles as weapons and as hunting implements. They were also important because their relatively complex nature necessitated localized, frontier supply and repair; their use and maintenance were integrated into many facets of frontier life. Historical documents and archaeological materials show …

Optimal Energy Management For Forward-Looking Serial-Parallel Hybrid Electric Vehicle Using Rule-Based Control Strategy, Abhijit Bhaskar Jadhav

Masters Theses

In today’s sophisticated era of technology, resolving environmental problems is a matter of grave concern. Developing hybrid electric vehicles is a good step towards environmental preservation, since they use less fuel compared to conventional vehicles because of the combination of electric and mechanical energy. A hybrid electric vehicle reduces dependence on fossil fuels and hence lowers emissions. Specifically, a hybrid powertrain that includes a conventional gasoline engine and a brushless DC motor offers great potential to meet stringent CO₂ regulations and fuel economy requirements. This thesis focuses on the effects of initial state of charge (SOC) stored in Hybrid …

In 2003, the Russian government established an energy policy aimed at reducing the negative impacts of industry on the environment and improving the nation’s environments as a whole. This study analyzes deforestation and logging activities in the forests along the Amur River in Khabarovsk Krai in the Russian Far East to determine the effectiveness of Russian government policy in achieving the goals put forward in the 2003 energy policy. Changes in land-use and land-cover will be assessed using 500-meter resolution …

A Descriptive Analysis Of Restrictive And Intrusive Procedures In Behavior Support Plans, Kelsey Webster

Masters Theses

Restrictive and intrusive procedures are used in the course of effective treatment to protect the safety of clients and others. Nonetheless, behavior analysts have an ethical obligation to implement the least restrictive procedures possible that are still deemed effective. However, when fading procedures for restrictions and intrusions are not a mandatory component of behavior support plans, these procedures may be in place longer than necessary. Extended utilization of restrictive and intrusive procedures could be viewed as limiting the client’s rights, especially if less restrictive procedures would also produce successful outcomes. One reason that these procedures are overused may be that …

A Fea/Cfd Study Of Heat Transfer To Semi-Trailer Disc Brake Wheel-End Components During A Braking Event, Justin P. Fisher

Masters Theses

Foundation air disc brakes bring Class 8 semi-trailers to a stop by converting kinetic energy into thermal energy. Recently, side skirts have been added to the underside of semi-trailers to improve fuel economy. The reduction in airflow under the trailer they create has potential to increase brake temperatures by reducing convection heat transfer. This will require an increase in conduction and radiation heat transfer to the surrounding wheel-end parts. Additional heat transfer to the surrounding parts could increase the temperatures in the hub and bearing to damaging levels.

CFD analyses were developed to model the airflow under the semi-trailer with …

The Effects Of English Pronunciation Instruction On Listening Skills Among Vietnamese Learners, Nguyet Nguyen

Masters Theses

Listening has been a neglected skill in both second language research and teaching practice (Khaghaninejad & Maleki, 2015; Nowrouzi, Tam, Zareian & Nimehchisalem, 2015) and recent research has shown that second language (L2) listening difficulties might relate to phonological problems besides syntactic and lexical knowledge (e.g., Suristro, 2018). There have been some empirical studies examining the effects of phonetic instruction on perceptual skills showing promising results (e.g., Aliaga-Garcia & Mora, 2009; Linebaugh & Roche, 2013). This study contributes to this area with a focus on investigating the impacts of English pronunciation instruction on listening skills among Vietnamese English as a …

Swearing In A Second Language, Grace Irwin

Masters Theses

Second language learners often lack knowledge of L2 swear words, their appropriateness, and pragmatic function. Competence in L2 swearing is important for L2 learners to be able to express themselves expertly and understand others’ emotional expressions precisely. However, taboo language is rarely included explicitly in L2 curricula due to its controversial nature. This paper addresses a gap in the literature concerning what second language users actually know about swearing in their L2. Some studies have attempted to determine learners’ receptive swearing competence (Jay & Janschewitz, 2008; Kapoor, 2016); however, the present study employs an updated measure of L2 pragmatic swearing …

Cfd Study Of Aerodynamic Drag Reduction Tool Of A Generic Sports Utility Vehicle (Suv), Samira Ishrat Jahan

Masters Theses

The Sports Utility Vehicle (SUV) has been a popular automobile choice in North America for over 50 years due to its seating and hauling versatility and good towing capacity. This widespread popularity has resulted in manufacturers pushing for increased horsepower and cabin size. Unfortunately, the limiting factor has been fuel economy which is governed by the vehicle aerodynamics. A reduction in aerodynamic drag can result in better fuel economy. The goal of this study is to reduce the aerodynamic drag of a generic SUV and the efficient application of drag reduction devices to control flow separation. An initial study has …

Influences On International Saudi Students’ Sojourner Acculturation In The U.S., Abdulah Shaban Alasiri

Masters Theses

Research on international students’ experiences in tertiary institutions abroad suggest they face difficulties related to culture, language, and socialization (e.g., Andrade, 2006; Hellsten, 2002). To encourage more successful socialization and English language development, the Saudi Arabian Cultural Mission established a cap on the enrollment of Saudi students in any institutions abroad since 2014. The effectiveness of these quotas in promoting socialization is not known, but anecdotal evidence and an exploratory study conducted by the author suggest other (perhaps more influential) factors affecting Saudi students’ opportunities for socialization (in this study defined more specifically as sojourner acculturation) and subsequent language development. …

To Study The Current Distributions Of An Antenna In Magnetized Collisional Plasma Via Pffdtd Simulations, Sindhuja Moravineni

Masters Theses

This thesis paper talks about the study of current distributions on dipole antenna immersed in collisional plasma. Analytical models like Balmain’s[6] one dimensional triangular current distribution, Staras[8] proposed and developed by Nikitin’s[10] threedimensional exponential current distribution and the PF-FDTD (Plasma Fluid- Finite Difference Time Domain) model[11] are compared against the Auroral Space Structure Probe (ASSP) flight data in order to show how data analysis can benefit. PF-FDTD model is used to study the antenna in weakly collisional plasma and the comparisons of the analytical and numerical solutions show that numerical model match better for data analysis of flight data sweeps …

The Acute Effects Of Melatonin On Striatal Dopamine Release: Progressive Electrochemical Analysis In An Ex Vivo Mouse Model Utilizing Fast Scan Cyclic Voltammetry, Kevin D. Hughes

Masters Theses

The caudate putamen is a sub region of the basal ganglia, containing neural tracts important for cognition, reward learning, and voluntary motor function. Dopamine (DA) signaling received from the dopaminergic neurons of the substantia nigra pars compacta mediate locomotion, degradation of which is the characteristic neuropathology for Parkinson’s disease (PD). PD is an initially neurovegetative motor disorder but can progress to include cognitive impairments as well. Sundowner’s syndrome (SS) has been observed in patient populations with neurodegenerative diseases, characterized by the decline of cognition into evening hours. Due to the circadian influence which the hormone melatonin has on the sleep-wake …
