To effectively replace conventional methods, batteries will need to be charged quickly while accounting for degradation to maximize lifetime. Further, larger batteries require more detailed safety monitoring, which is implemented using a battery management system (BMS). A BMS is responsible for state of charge (SOC) estimation, state of health (SOH) estimation, cell balancing, regulating voltage and current according …

Seed Modeling Of An Esd Gun Discharge To A Usb Cable, Yang Xu

Masters Theses

“An IC protected by a transient voltage suppression (TVS) diode may fail if the TVS device does not turn on or does not turn on quickly enough, causing the IC to take the full brunt of the electrostatic discharge (ESD) event. Transient simulation models have been developed for ESD protection devices for the purpose of system-efficient ESD design (SEED). The TVS modeling methodology has been improved to better represent the physics that occurs during the TVS response and more accurately predict the interactions between off-chip and on-chip protection devices. Moreover, a complicated test scenario -- an ESD gun discharge through …

Topological Biclustering Artmap, Raghu Yelugam

Masters Theses

”Detection of gene mutations is central for assessing genetic factors affecting disease predisposition, genetic causes of a particular disease, and gene-targeted treatment. DNA microarray methods are widely used to detect mutations by contrasting the expression levels of thousands of genes together under varying experimental conditions. The experimental conditions could be diseased cell states compared with the normal cell states. Biclustering, a robust exploratory data analysis tool, can be applied to microarray data to detect subsets of genes that co-express highly only for a subset of experimental conditions.

Federalism, Constitutionalism, And The Texas Revolt, John Leslie Hancock

Masters Theses

Traditional historiography characterizes the period directly following Mexico's independence as one during which the adoption of federalism divided a previously united and uniformed country. Anglo-American settlers in Texas sought to remove the territory from Mexican control by exploiting the resultant political turmoil. This exploitation eventually led to the Texas revolt of 1835, its independence as a republic, and, ultimately, statehood within the United States. The recent focus on Mexico's provincial history challenges this narrative by illustrating that independence did not result in a unified nation. On the contrary, comprising multiple provinces with varying interests, the region's Provincial Deputations adopted federalism …

Debt, Death, And Deregulation: Neoliberalism, Human Rights, And American-Argentine Relations, 1976-1983, Billy Davis

Masters Theses

Between 1976 and 1983, Argentina was governed by a military government that oversaw both a brutal campaign against communism and a process of neoliberalization. During this period, the United States provided substantial economic support to Argentina through its approval of loans that enabled Argentina’s economic transformation. Early on, the United States was largely apathetic and complacent in regard to Argentina’s Dirty War. During the administration of Jimmy Carter, the United States attempted to confront the Argentine military government about its human rights abuses. However, a substantial contingent within the Carter administration pushed back against this initiative and worked to protect …

Chreia And Lives Of Saints: A Study Of Hagiography As An Evolved Rhetorical Genre In Late Antiquity, Seth Fisher

Masters Theses

Hagiography has often confused historians over what practical application this genre of Christian literature has when read as primary sources. In this project I will show that hagiography can read as an evolution of an earlier pagan style rooted in the paideia of ancient scholars. Chreia exercises were performed by students of paideia in order to instruct them on how to write about figures worth emulating such as Diogenes or Alexander the Great. Christian authors did not participate in a hermetically sealed education system but took part in the same schooling as their pagan peers. Hagiographies are structurally and functionally …

When used correctly, praise is a simple and effective strategy that can be used by staff school-wide to improve student disruptive behavior. Unfortunately, many teachers report receiving little classroom management training and feeling unprepared to manage student problem behavior. Therefore, having an assessment tool that identifies which educators may benefit from additional training may better guide training and therefore increase educators’ effective use of praise. The present study attempted to revise a previous iteration of the Praise Knowledge Assessment for Teachers and Educators (PKATE), examine educator’s knowledge and attitudes toward praise, and determine whether there is a relation between teachers’ …

Trade Integration And Economic Growth In Africa: Lessons From Sadc And Ecowas Regional Trading Blocs, Kofi Ampoma Asuako

Masters Theses

The literature on the effects of free trade agreements (FTA) or trade liberalization on economies is vast and tends to focus on the post-liberalization performance of countries, particularly in Europe and North America. However, an analysis of how varying levels of integration within free trade blocs in Sub-Saharan Africa affect economic growth does not appear to be in the international economics literature. This analysis is vital as 54 out of 55 African union member States have begun trading under the African Continental Free Trade Agreement (AFCFTA) which intends to gradually decrease and ultimately do away with customs duties and non-tariff …

Immediate Response Of Black Basses To Dam Removal Is Determined By Habitat Preference, Reuben Frey

Masters Theses

Dams affect the abundance of fish species in lotic systems by altering flow regime and available physical habitat. Removal of dams may mitigate these effects and generate a change in species abundance and fish community structure. Understanding the effects of dam removal on gamefish species is essential in making management decisions. I investigated how populations of Smallmouth Bass (Micropterus dolomieu), Spotted Bass (M. punctulatus), and Largemouth Bass (M. salmoides) were affected by the presence and removal of two low-head dams in a Midwestern river system.

The Effect Of Mortality Salience On Compromising Mate Selection Standards In Homosexual And Heterosexual Individuals, Sydney Rohmann

Masters Theses

Terror management theory (TMT), proposed by Greenberg, Pyszcynski, and Solomon (1986), suggests that humans cope with terror resulting from the knowledge of their own mortality. The need for coping mechanisms arises when individuals are reminded of their own inevitable death; that is, when they experience mortality salience (MS). Hirschberger, Florian, and Mikulincer (2002) found that when primed with death reminders, heterosexual individuals tend to compromise their ideal mate selection to form close relationships. There has also been extensive research on the differences between homosexual and heterosexual mating preferences. This study examined the effect mortality salience has on an individuals’ mate …

An Exploration Of The Perception Of Faith Development At A Midwestern Public Institution, Zachary Sandoval

Masters Theses
