Predicting Radiated Emissions From A Cable Harness Through Component Level Tests, Fuwei Ma

Masters Theses

“In this work, a procedure is developed to predict the radiated emissions from a cable harness using component-level tests. Direct measurement on the engine control unit is utilized to accurately characterize the equivalent common mode source voltages and impedance associated with the device. The cable harness geometry is reduced using the equivalent cable bundle approach by lumping wires according to the source and load impedance compared with characteristic impedance of the harness, which dramatically reduces the measurement effort and allows practical 3D full-wave simulation of the radiated emissions. Radiated emissions are predicted from an engine control unit (ECU) and an …

Zinc Plating From Alkaline Non-Cyanide Bath, Abdul J. Mohammed

Masters Theses

“Alkaline non-cyanide zinc plating baths are preferred when trying to avoid the toxicity of cyanide baths or corrosivity of acid baths. Without additives, alkaline zincate baths produce powdery non-adherent deposits which have no use in commercial plating. Additives must be added at optimum concentrations to produce adherent, bright and uniform zinc deposits. In this study electrochemical tests were used to determine effects of additives on cathodic polarization, throwing power and morphology of deposits. Current density distribution in a unique bath of 37.5 g L^-1 Zn and 210 g L^-1 NaOH was modelled using COMSOL and validated two plating …

One of the most common end-of-life (EoL) choices that can lead to a circular economy is remanufacturing. As a result, at the end-of-life stage of a product, it is critical to prioritize this choice over other accessible options because it is the only recovery option that retains the same quality as a new product. This work focuses on the numerous technologies that can aid in the improvement of smart …

Validation Of Athlet-Cd With Cora-28 Test, Murat Tuter

Masters Theses

“Following the incidents at Chernobyl and Fukushima, severe accidents at nuclear power plants (NPP) have become a global concern. These accidents generally occur because of a failure in the reactor cooling system (RCS) and result in the melting of the reactor core and fission product release. This event is mostly caused by a LOCA, loss of flow accident, station blackout or loss of heat sink. During a severe accident, generation of hydrogen as a result of steam-zircaloy fuel cladding is a significant safety concern. To better understand and prevent the hydrogen generation issue, safety related experiments and safety related codes …

Several Problems In Nonlinear Schrödinger Equations, Tim Van Hoose

Comparing Macroinvertebrate Total Abundance And Total Biomass On Five Substrate Types From Upstream To Downstream On The North Branch Of The Au Sable River, Paul David Dingman

Masters Theses

The North Branch of the Au Sable River is located in the northern lower peninsula of Michigan and is known for prolific hatches of Ephemeroptera (mayflies), Trichoptera (caddisflies), and Plecoptera (stoneflies). Macroinvertebrates play an important role in processing and recycling organic material in rivers and are a valuable food source for trout. In 2018, anglers were reporting catching fewer numbers of brook and brown trout (Salmo trutta and Salvelinus fontinalis). The Michigan Department of Natural Resources (MDNR) determined significantly lower abundance than the historical average. We hypothesized that trout abundances were lower due to a lack of prey …

A Parametric Computational Fluid Dynamics (Cfd) Study Of In-Line Horizontal Axis Wind Turbines (Hawts) With Yaw, North Alyster Yates

Masters Theses

Because of the constant use of non-renewable fossil fuels, and the enormous impact they have on global warming and pollution, there has been a push to use more eco-friendly and renewable sources for power. One such form is wind power via turbines. The most common form, Horizontal Axis Wind Turbines (HAWTs), can generate massive amounts of power. However, they also have a serious flaw in their design.

Visual Catechesis: Utilizing Pictorial Illustrations To Facilitate Learning And Retention Of Protestant Doctrine In The United States, Robert Christian Hemme

Masters Theses

A lack of catechetical instruction within contemporary Protestantism in the United States has resulted in a large number of self-identifying Christians not knowing important tenets of their faith. The modern era also presents a unique dilemma in that North American culture is steeped in visual stimuli due to technology, so that even were catechistic instruction revived, many individuals might balk at a traditional, text-centric process. This thesis explores improving comprehension and retention of orthodox Protestant doctrine in the United States through integrating pictorial illustrations into the classic Christian pedagogical methodology of catechesis. Because of unceasing debates surrounding numerous, nuanced theological …

Traversing The Back Door Of The Mind: Directing Imaginative Stories To Generate Meaningful Dialogue About Biblical Truths In A Materialist World, Heather Jean Birkeland

The writer provides an overview of the philosophy of ontological materialism and its effects on people, the impact of imaginative storytelling, and the psychology of narrative persuasion. Firstly, the selected thesis topic will explore how non-Christians could potentially approach and engage in biblical truths without hostility through the …

Questions With Purpose: Utilizing Technology To Maximize The Parent/Child Reflective Discourse, Earl Tubbs

Masters Theses

For a young child, parents are the “no one” and “everyone” that Saint Augustine spoke of. Providing a positive example through action is important but shaping their moral compass by reflecting on their life experiences is equally important. Stated succinctly, reflective discourse is an interactive conversation between parent and child where the parent guides one’s children through recent life experiences, viewed through a specific lens. By reviewing logic driven and emotional responses, the positive and negative consequences to their behavior, and the people involved, parents can aid their children as they shape their definition of right and wrong. By reviewing …

The Pedagogical Value Of Andrew Lloyd Webber's Music In A New Jersey Elementary Music Setting, Eric James Mclaughlin

Masters Theses

Elementary music educators’ analyze and select song repertoire based upon a variety of factors and influences. These can include an educator’s level of training, the preexisting standard song literature collection, resources obtained in undergraduate study, the context of the song material, and a song’s pedagogical application. Educators must be selective when choosing literature for pedagogical purposes, such as teaching specific melodic and rhythmic elements. The vast body of musical literature by renowned theatrical composer Andrew Lloyd Webber is not often used for that purpose in the elementary general music classroom. In addition, a recent national effort calling for the reexamination …

Improvisation And Interpretation For High School Instrumental Students, Jeffrey J. Bianchine Jr.

Masters Theses

Improvisation is associated with jazz or rap in modern western culture, but classical music has a long tradition of improvisation featuring famous improvises such as Mozart and Liszt. Improvisation develops critical thinking and problem solving, essential skills in the American job market. The typical instrumental student does not often get the opportunity to use this. Bloom’s Taxonomy explains that students who do critical thinking activities in class have a better understanding of the course material. This course will equip students to improvise with others, make executive decisions about artistic elements in the repertoire, self-cretic playing, and compose a short cadenza.

Restoring Female Agency: Wicked As A Feminist Fairy-Tale Revision, Erica Nicole Fox

Masters Theses

One method of promoting gender equality that has gained popularity in recent years involves revising the fairy tales, primarily the ones compiled and revised by Charles Perrault, Hans Christian Anderson, and the Grimm brothers, to create versions in which the female characters have agency and purpose outside of furthering patriarchal gender ideals. The primary goal of the feminist fairy-tale revision is to give the female characters agency, not because they are women, but because they are functioning characters within the story. While there are many authors who attempt to create fairy-tale revisions that embody a feminist perspective, not all are …

The Meaning Of Movement: Using Motion Design To Enrich Words For Deaf And Hard Of Hearing Children, Hannah Elyse Colasurdo

Masters Theses

This thesis aims to address challenging areas of vocabulary for deaf and hard of hearing children by developing an open resource for students, parents, teachers, and content creators that utilizes motion to enhance written words for deaf and hard of hearing children. This research seeks to study the means of nonverbal communication such as body language expression and paralinguistic prosody (i.e., tone, intonation, volume, and pitch) qualities within the framework of graphic design through motion design. Body movement and expression are essential during face-to-face communication, but written language lacks such context clues. Additionally, the hard of hearing may not fully …

Police Perceptions And Parenting Styles Among Black Parents Of Miami-Dade County, Amber E. Roach

Masters Theses

A person’s perception of something or someone does not develop without external factors affecting the individual. Experiences and lessons people have learned from a young age have molded their perception of the world. One of those lessons is what is considered correct and what is not. In the Black American community, this is accompanied by the “talk”. This “talk” is shaped by past experiences with the police towards minority groups, specifically, Black Americans. This paper discusses how parenting styles, race, and authority intersect. The purpose of this paper is to examine the beginnings of one’s life, the lessons they are …

Using Sedimentary Mercury Geochemistry To Evaluate The Niagara-Salina Transition, Silurian Michigan Basin, Usa, Sara Hayes

Masters Theses

The Niagara-Salina boundary in the Michigan Basin is marked by an abrupt transition from carbonates to evaporites. Though the cause is uncertain, previous work suggests the onset of Salina evaporites was driven by basin restriction, but the presence of several global carbon isotope excursions (CIE) suggest a global driver. This study builds on this discussion using two relatively new geochemical proxies - elemental mercury concentrations [Hg] and Hg isotopes.

Mercury concentrations [Hg] were measured in 88 samples from the State Kalkaska #2-15 core from 6604.03 ft to 6797.42 ft. [Hg] ranges from 0.11 to 0.62 mg/kg and [Hg]/TOC from 0.038 …

Exegesis: Mark 6:30-44, Younggwang Kim

Masters Theses

Jesus’ feeding the five thousand is the only miracle that the four Gospels commonly recorded among the miracles Jesus Himself performed. The feeding miracle episode is like the gem, which changes light colors slightly depending on how people see it.
