These large amounts of online data, often referred to as data streams, because they get generated at extremely high throughputs or velocity, can make conventional and classical data analytics methodologies obsolete. For these reasons, the issues of management and analysis of data streams have been researched extensively …

All-Optical Switching In Ferromagnetic Superlattices., Faren Hoveyda Marashi

Electronic Theses and Dissertations

The unexpected observation of ultrafast demagnetization (UDM) and subsequent time-resolved studies of laser-induced magnetization switching opened a new door to both fundamental physics and technological applications of magnetic materials. All-optical switching (AOS) can be initiated faster than the precession limit, hinting to its potential in increasing the writing speed and data storage density. However, notwithstanding considerable research interest, the mechanism of AOS in ferromagnetic materials remained unclear.

Ferromagnetic superlattices were deposited on glass substrates with e-beam evaporation and sputtering. Magnetization curves were measured in magneto-optical and vibrating sample magnetometer experiments. A femtosecond Ti:S laser was utilized in a writing setup …

Southern Veils : The Sisters Of Loretto In Early National Kentucky., Hannah O'Daniel

Electronic Theses and Dissertations

This thesis analyzes the experiences of Roman Catholic women who joined the Sisters of Loretto, a community of women religious in rural Washington and Nelson Counties, Kentucky, between the 1790s and 1826. It argues that the Sisters of Loretto used faith to interpret and respond to unfolding events in the early nation. The women sought to combat moral slippage and restore providential favor in the face of local Catholic institutional instability, global Protestant evangelical movements, war and economic crisis, and a tuberculosis outbreak. The Lorettines faced financial, social, and cultural pressures—including an economic depression, a culture that celebrated family formation …

The Knowledge Economy : Increasing Human Capital On The U.S. I-65 Corridor., Brandon S. Mcreynolds

Electronic Theses and Dissertations

In economics, the term growth often refers to the increase in economic activity between two points in time. Within the context of the United States of America, the language of growth has permeated beyond just economics and into other societal institutions due to spillover. As a result, growth is not just an economic term but rather a part of the culture of capitalism which impacts every area of society. The dissertation using growth machine theory and the global cities literature examines how in the knowledge economy, cities play a growing role in mediating the supply and demand for …

Pcb-Associated Steatohepatitis And The Role Of Nuclear Receptors., Heather Brooke Clair

Electronic Theses and Dissertations

Metabolic diseases, including fatty liver disease, hyperglycemia, and obesity, result when body systems responsible for managing allostasis (dynamic homeostasis across systems) are pressured beyond their collective compensatory reserve. Nutritional excess contributes to this state, the capacity of which is limited by genetic variation, and failure of one system will gradually lead to pathological overload in the others. Agents which act directly on the communication machinery linking these connected systems can also change the point at which allostatic load becomes allostatic overload. Environmental exposure to polychlorinated biphenyls (PCBs), a class of persistent organic pollutant, is associated with a specific form of …

Numerical Investigation Of Drop Impingement On Dry And Wet Surfaces., Yisen Guo

Electronic Theses and Dissertations

In-flight icing due to supercooled large droplets (SLDs) imposes great danger on aviation safety. Because of the large size, SLDs have different characteristics than typical cloud droplets that most icing encounters involve. As a result, SLDs more likely hit the wing surface and move into areas not protected by de-icing devices to form ice, which can lead to loss of lift, increase in drag, altered controllability, and eventually stall and loss of control of the aircraft. The phenomenon of droplet splashing is considered as the most important aspect of the SLD icing accretion problem. Although previous studies have established splashing …

Emotion Socialization And Families Of Children With And Without Adhd., Danielle M. Walerius

Electronic Theses and Dissertations

Emotional competence (EC) represents several distinct emotional skills found to be strongly associated with children’s socioemotional outcomes. EC is thought to develop through a process known as emotion socialization (ES), whereby children’s emotions and emotion-based behaviors are socialized through interactions with parents and/or other primary figures. The present study examined ES across families of children with and without ADHD in order to clarify the role ES plays in the development of EC in typically developing (TD) children versus children more prone to EC impairments due to intrapersonal characteristics (e.g., inattention, disinhibition, etc.). Forty-eight children 5 to 8-years-old (23 with ADHD, …

Heterogenization Of Complexes With Redox Active Ligands For Hydrogen Evolution Reaction., Wuyu Zhang

Electronic Theses and Dissertations

Hydrogen fuel is a promising future energy carrier with many applications. Thermodynamically, 1.23 V is needed for the water electrolysis, which is a clean method to generate hydrogen gas. In practice excess potential is required, which is called overpotential, due to kinetic barriers. Catalysts to reduce the overpotential for the hydrogen evolution reaction (HER) include many homogeneous catalysts and heterogeneous catalysts. Heterogenization of homogeneous catalysts on electrode surfaces is an ideal way to study a catalyst by combining homogeneous and heterogeneous study together. In this dissertation, several characterization techniques have been employed, include cyclic voltammetry, linear sweep voltammetry, electrochemical impedance …

Computational Investigation Of The Biomechanics Of Babywearing In Regards To Developmental Dysplasia Of The Hip, Gaurav Girish

Doctoral Dissertations and Master's Theses

Developmental Dysplasia of the Hip (DDH) is a congenital condition where an infant’s hip socket is either loose or otherwise unstable. DDH causes a joint instability where the femoral head is not properly situated inside the acetabulum. Etiology of the condition is in part congenital and developmental, with a difference of DDH prevalence between ethnicities. Incidence of DDH is also in some part dependent on cultural practices and activities of the mother and child. The exact nature of this cultural incidence is not clearly understood. A computational approach is hypothesized to identify the impact of babywearing position on the healthy …

The Problem Of Illusion In The Phenomenology Of Claude Romano, Joseph Cutolo

Student Theses and Dissertations

The phenomenology of Claude Romano constructs a strict distinction between perceptions and illusions. This distinction is so strict that the former excludes the latter completely. Putting this distinction into play is not a local decision about our experiences and the structures of our experiences. This decision brings with it metaphysical, ontological, and phenomenological frameworks to ground it. In what follows I attempt to draw out the consequences of Romano’s decisions about our experience, and to study the philosophical frameworks that underlie his decisions. In doing so, I reconnect his phenomenology with a wider terminology of phenomenology, in order to study …

Better Fit: A Conceptual Solution For Seamless Exercise Experience, Hongwei Huang

Theses

The development of fitness technology has changed the way we exercise over time, and each technology has allowed people to exercise independently in various ways, such as wearable devices, fitness apps, game consoles, and even social media. The consequence is that more people get used to exercising solely with their digital device and get motivated from virtual communities rather than in a real environment. However, the research shows there can be even more benefit for people by exercising with others in a physical space.

The thesis utilizes UX design methodologies to develop a seamless-workout experience that enables a user to …

The Soul’S Speaker: Give Your Eyes Some Rest, Fuye Zhang

Theses

The students studying in colleges often fix their eyes on books, on computer screens and archives for a long time to gain knowledge. As a result of this, their eyeballs often turn red out of fatigue. Researches have shown that college students lack the awareness of the benefits of giving their eyes some rest. However, there are few of eye protection advertisements which suggest the need for students to give their eyes some rest. As a designer, I need to let people know the important roles that eyes play in the human body. I feel it is important for designers …

Dzone: An Interactive Platform For Designers Seeking And Sharing Ideas., Yidie Xue

Theses

The principle of design is to create something both beautiful and effective. However, not all designs are created equal. There are plenty of inefficient designs in existence. The reason is not because of bad designers, but because of the lacking platforms for designers to communicate and test their designs.

There are many tools available, both application and website, for designers to express their ideas. However, the majority of these resources are focused on sharing project on the social media and treat it like an element of personal portfolio. Platforms for designers to actually test their project, gathering critical product-developing feedback …

An Alternative Approach To Counting Minimum (S; T)-Cuts In Planar Graphs, Rachel E. Silva

Theses

Finding and counting minimum cuts in graphs can be useful in image processing and segmentation and in networking systems such as computer or road networks. Researchers have previously developed polynomial-time algorithms to count minimum cuts in planar graphs which utilize the relationship between maximum network flows and minimum cuts.

This thesis presents a polynomial-time algorithm to count the number of minimum (s,t)-cuts in a planar graph without first finding a maximum flow. The presented algorithm is dependent on the finding that (s,t)-cuts in a planar graph correlate to certain cycles found in the dual of that graph, which can be …
