Investigation Of Electrical Component Failures Affecting Vehicle Electronics, Dexin Zhang

All Dissertations

This dissertation describes three independent studies related to electrical component failures affecting vehicle electronics. The topics covered are: comparison of the accelerator-pedal-to-engine-control module (AP-to-ECM), the effect of electrical fast transients on multi-layer ceramic (MLC) capacitors, and electrical behavior of MLC capacitors damaged by electrostatic discharge.

The first chapter examines the AP-to-ECM interfaces of five vehicles equipped with electronic throttle control systems. All five vehicles employ simple voltage level sensing from two or three sensors in the accelerator pedal assembly. The purpose of the study is to identify any differences in the AP-to-ECM interfaces of vehicles with high reported rates of …

Fault Tolerance In Distributed Systems Using Self-Stabilization, Yihua Ding

All Dissertations

Self-stabilization is an optimistic paradigm to provide autonomous resilience against an un-limited number of transient faults in distributed systems. A self-stabilizing system guarantees an eventual return to a legitimate operating state beginning with an unknown initial state, including a state that arises as the result of an unanticipated transient fault (e.g., node failure, state corruption, or node mobility in mobile systems). This thesis focuses on the fault tolerance in distributed sys-tems using self-stabilization, and presents a collection of self-stabilizing algorithms for well-known problems in distributed systems.

Two variants of dominating set (i.e., weakly connected dominating set and positive influence dominating …

Retinal Synaptic Function In The Absence Of The On Pathway., Kathryn Marie Heath Fransen

Electronic Theses and Dissertations

Complete Congenital Stationary Night Blindness (cCSNB) is a rare hereditary retinal disorder characterized by abnormal night vision. cCSNB is caused by postsynaptic defects in On bipolar cells (BCs) and is identified by the presence of an electroretinogram (ERG) with a normal a-wave, corresponding to photoreceptor function, and the absence of a b-wave, corresponding to a failure of On BC function. Through the study of genetic mutations in mouse that result in no b-wave ERG phenotypes, several proteins have been identified that play crucial roles in On BC signal transmission. I focused on four mouse models of cCSNB; Nyxnob (Nyctalopin mutant), …

Study Of Novel Nanoparticle Transport And Drug Release For Cancer Treatment., Christopher Gene England 1988-

Electronic Theses and Dissertations

Nano-scale particles sized 10—400 nm administered systemically preferentially extravasate from tumor vasculature due to the enhanced permeability and retention effect. Therapeutic success remains elusive, however, because of inhomogeneous particle distribution within tumor tissue. Insufficient tumor vascularization limits particle transport and also results in avascular hypoxic regions with non-proliferating cells, which can regenerate tissue after nanoparticle-delivered cytotoxicity or thermal ablation. In this study, gold nanoparticles were functionalized with phosphatidylcholine (two-layer) or phosphatidylcholine and HDL (three-layer) in the formation of “layered” nanoparticles. The diffusivity of both two- and three layered colloidal gold nanoparticles and silica gold nanoshells were examined in 3D cell …

Electronic Theses and Dissertations

Much of the important writing students will be tasked with in their college careers calls upon them to approximate the writing styles academics and professionals use to shape and advance their respective fields. Many disciplinary values are encoded within the such texts. Learning these styles can be difficult for students who lack the experience and ingrained habits that their instructors may take for granted. In most cases, college writers are outsiders peeking in from the outskirts of academic and professional discourse. Also, the “Expert Blind Spot” (Ambrose et. al) can make college instructors oblivious to the nuances of the writing …

Transfer And The Commodification Of Practice., Kenneth Andrew Smith

Electronic Theses and Dissertations

This dissertation engages in a close reading of the research in composition on transfer, a concept that refers to how the practices learned in one situation influence what a person can do in a future situation. In the studies that have appeared over the last two decades, the results have indicated that not much transfers between writing courses and future contexts, whether they be disciplinary courses or professional workplaces. Yet, despite the increasing prominence of transfer research, little time has been spent discussing the uses and limitations of the concept. To better understand its growing popularity among researchers, I examine …

The Effect Of A Controlled Frequency Breath Holding Training Program On Running Economy Among Elite College Swimmers., Patrick Sims 1988-

Electronic Theses and Dissertations

Running economy (RE) is the amount of oxygen consumed while running at a submaximal intensity. Along with aerobic capacity (VO2max), RE is an important predictor of running performance. Little research has investigated changes in RE with restricted breathing training [i.e. controlled breath-holding (CFB)] during exercise. RE may improve ~6% amongst a novice swimming cohort through CFB training, but this has not been established in elite swimmers. The purpose was to further establish that CFB training (16 sessions of 12 x 50-m with ~15 seconds rest between each 50-m, using only ~2 breaths per 50-m) can improve RE in 25 elite …

Functional Characterization Of The Arginine Vasotocin 4 Receptor (Vt4r) In Sensory Circumventricular Organs Of The Chicken Gallus Gallus, Nguiessan Alphonse Aman

Graduate Theses and Dissertations

Past studies have shown that the avian vasotocin 4 receptor (VT4R), homologous to the mammalian arginine vasopressin receptor 1a (V1aR/AVPR1A) is involved in immobilization stress. It was not known, however, whether the receptor is also associated with osmotic stress, and if so, what brain regions may be involved. Four treatment groups of chicks were used for the study. One group was subjected to 1h immobilization stress and two groups were administered intraperitoneal injection of 3 M NaCl or 0.15 M NaCl. One additional group served as controls. After 1 h, blood samples were taken for the determination of plasma levels …

Investigation Of Nuclear And Cytoplasmic Functions Of The Dlipin Protein Of Drosophila Melanogaster, Qiuyu Chen

Graduate Theses and Dissertations

Lipin family proteins are highly conserved proteins present in species ranging from mammals to yeast. Lipin 1, the first Lipin gene identified in fatty liver dystrophy (fld) mutant mice, encodes the bifunctional protein Lipin 1, which can serve as an Mg2+-dependent phosphatidic acid phosphatase (PAP) and transcriptional co-regulator. dLipin, the single Lipin ortholog of Drosophila melanogaster, is required in triglyceride synthesis and fat body development. To study the transcriptional co-regulator activity of dLipin, nuclear receptors were screened to find receptors that interact with dLipin. The genetic interaction data indicated that Drosophila hepatic nuclear receptor 4 (HNF4) was a promising candidate …

Government Dependency Theory: Public Services, Banking Crisis, And The Likelihood Of Protests, Titus Bickel

Arts & Sciences Graduate Student Theses and Dissertations

The purpose of this research is to determine what causes certain countries to experience mass protests during economic crises while other governments weather the same events and emerge unscathed. Further research on this topic could predict the likelihood of protests that lead to state collapse in countries like Ukraine. I argue that high gross domestic product expenditure on social services creates a dependent society that will protest when those goods and services are threatened by banking crises. I originated this theory and titled it the Government Dependency Theory. My theory uses data from 147 banking crises occurring in 115 countries …

Hadrian's Wall: A Study In Function, Mylinh Van Pham

Master's Theses

Earlier studies on Hadrian's Wall have focused on its defensive function to protect the Roman Empire by foreign invasions, but the determination is Hadrian's Wall most likely did not have one single purpose, but rather multiple purposes. This makes the Wall more complex and interesting than a simple structure to keep out foreign intruders. Collective research on other frontier walls' functions and characteristics around the empire during the reign of Hadrian are used to compare and determine the possible function or functions of the Wall. The Wall not only served political purposes, but also had economic and social uses as …
