A Novel Splitting Beam Laser Extensometer Technique For Kolsky Tension Bar Systems, Colin Loeffler

Mechanical Engineering Research Theses and Dissertations

The Kolsky (Split Hopkinson) Bar has become a well-known and established experimental technique for characterizing the mechanical behavior of materials subjected to dynamic loading conditions. Kolsky bar based experimental techniques facilitate the application of controlled and repeatable dynamic loading conditions to a specimen as well as the high resolution measurement of the resulting mechanical response. In recent decades the technique has been refined and adapted to provide more complex dynamic stress-states beyond uniaxial compression. However, the increasing complexity of the experimental apparatus introduces uncertainty to the traditional specimen deformation measurement techniques.

In this thesis, a direct non-contact optical measurement technique …

Non-Classical Plate Models Incorporating Microstructure And Surface Energy Effects: Their Variational Formulations And Applications, Gongye Zhang

Mechanical Engineering Research Theses and Dissertations

In this dissertation research, new non-classical models for Kirchhoff and Mindlin plates are developed and applied to study band gaps for flexural wave propagation in composite plate structures.

In Chapter 2, a new non-classical model for a Kirchhoff plate resting on an elastic foundation is developed using a modified couple stress theory, a surface elasticity theory and a two-parameter elastic foundation model. A variational formulation based on Hamilton’s principle is employed, which leads to the simultaneous determination of the equations of motion and the complete boundary conditions and provides a unified treatment of the microstructure, surface energy and foundation effects. …

Quantum Extension Of The Kruskal Spacetime, Abhay Ashtekar, Javier Olmedo, Parampreet Singh

Faculty Publications

A new description of macroscopic Kruskal black holes that incorporates the quantum geometry corrections of loop quantum gravity is presented. It encompasses both the "interior" region that contains classical singularities and the "exterior" asymptotic region. Singularities are naturally resolved by the quantum geometry effects of loop quantum gravity. The resulting quantum extension of spacetime has the following features: (i) It admits an infinite number of trapped, anti-trapped and asymptotic regions; (ii) All curvature scalars have uniform (i.e., mass independent) upper bounds; (iii) In the large mass limit, all asymptotic regions of the extension have the same ADM mass; (iv) In …

Design, Synthesis, And Evaluation Of C5 Substituted Carbapenem Antibiotics To Counter Resistant Pathogens, Noora Mohammed S.A Al-Kharji

Chemistry Theses and Dissertations

The 21st century has seen a dramatic acceleration in the evolution of bacterial resistance. Many classes of commercial antibiotics, including most current commercial β-lactams, were structurally optimized to counter 20th century pathogens. The carbapenems represent the most potent and broadest spectrum of the β-lactams, representing crucial last line agents to treat lifethreatening infections. While the 21st century has seen the appearance of carbapenem-resistant strains, the basic substitution pattern of commercial carbapenem antibiotics has remained constant, other than minor modifications at the C2 position. This research will investigate whether substitution at an atypical carbapenem position, the C5 position, can improve the …

The Installation Of The Human: Whiteness, Religion, And Racial Capitalism, Benjamin Robinson

Religious Studies Theses and Dissertations

Over the past thirty to forty years, the academic study of religion has brought the category of religion into crisis, unveiling its Christian architecture and its formation as a settler-colonial category of European expansion. While the proliferation of research on the genealogy of religion has opened new and important vantages for study, we remain conflicted about what is at stake. In this dissertation, I argue that the modern-colonial construction of religion is organized by a racial-theological operation that categorically separates people into humans, subhumans, and nonhumans, by which the social, economic, and political inequalities of racial capitalism have been made …

Racial Integration And White Supremacy In America: Can America Integrate Its Power Structures And Liberate Them From White Supremacy, Billy Lane

Graduate Liberal Studies Theses and Dissertations

Neither the presence of black people in predominantly white spaces nor the appropriation of black culture are indicators of racial justice. Power structures must be integrated even more so than subdivisions, classrooms, breakrooms, church pews, and pop culture. This thesis will explore the absence of African-American leadership from the highest ranks of our power structures that are central to contemporary life and the dynamics within each of these power structures that help to protect white supremacy and therefore maintain segregation.

Between Developed And Emerging Markets: Globalization Of Large Consumer Good Enterprises, Christine Savino Ms.

Honors Scholar Theses

A few years ago, The Economist promulgated that “the only way that companies can prosper in [emerging] markets is to cut costs relentlessly and accept profit margins close to zero” (The Economist, 2010). Likewise, according to the World Bank’s 2018 Ease of Doing Business Index[1], the least ranked countries (#94 and under out of 190 countries) are solely undeveloped and developing, while the top 20 countries are solely developed economies (World Bank, 2018). It has been long held that emerging markets[2][3] are non-strategic investments for multinational expansion, and that business giants from …

"Who Are These Wild Indians": On The Foreign Policies Of Some Voluntarily Isolated Peoples In Amazonia, Peter Gow

Tipití: Journal of the Society for the Anthropology of Lowland South America

This paper is a reflection on the phenomenon of voluntary isolation in Amazonia, about anthropology’s implication in its formation as a concept, and what anthropologists might profitably say about it as a concrete phenomenon in the world. While knowledge based on ethnographic fieldwork might by minimal or even totally absent for people in voluntary isolation, anthropological research has produced a very impressive understanding of indigenous Amazonian social forms in general, knowledge that can be brought to bear on the question.

Making Space For Makerspace: How Adding A Makerspace Can Benefit Art Museum Education Programming, Kaeleigh Thorp

Master's Projects and Capstones

In this capstone project, I advocate for adding makerspaces to art museum education programming. I review the foundational educational concepts of a makerspace which help explain why it is a modern strategy to increasing visitor learning. This includes John Dewey’s theories of experience and education, Howard Gardner’s multiple intelligences theory, George Hein’s studies of museum visitor behavior, and the physiological science of learning. I then propose four key terms essential for visitor learning, and explain how makerspaces successfully incorporate them. The four key terms are: 1. multiple intelligences, 2. direct experience, 3. inquiry based and open ended learning, and 4. …

Expanding The Definition Of Provenance: Adapting To Changes Since The Publication Of The First Aam Guide To Provenance Research, Katlin Cunningham

Master's Projects and Capstones

In 2001 the American Alliance of Museums (AAM) published The AAM Guide to Provenance Research. However, in the past seventeen years there have been several new developments in the provenanceresearchfield, and an updated guide has yet to be released. I propose that several changes be made to create an updated version. For this project, I tested this guide in two ways: first, to see how our understanding of provenance has changed since 2001 and second, to use a case study to assess whether the recommended basic research guide and principles still apply to today.

In the first …

The Dominican Liberator: Father Edward Paul Doyle, O.P.’S Response To The Holocaust, Jacqueline Michels

History & Classics Undergraduate Theses

Individual survivors and witnesses to the Holocaust each remember and reflect on their experiences differently. Some are angry at the Nazis for their inhumane actions. Some are angry at God for allowing these evils to take place. Others learned from their experience. Edward Paul Doyle, O.P. was one of the latter. A Dominican Friar at Providence College, he served as an army chaplain for the United States Army in Germany during World War II. While in Germany, Father Doyle helped to liberate Nordhausen concentration camp where he witnessed the horrors of the Holocaust. Father Doyle recorded his experience and reflections …

A Framework To Capture Dynamic Traffic Trends From Historical Sensor Data, Carlos Gaviria

UNLV Theses, Dissertations, Professional Papers, and Capstones

The typical approach of increasing infrastructure to alleviate traffic issues such as congestion is becoming unviable due to limited space, high cost, and associated externalities. Control and management strategies using Intelligent Transportation Systems (ITS) seek to maximize the use of existent infrastructure. Many ITS strategies, such as the deployment of information, require or benefit from knowledge about traffic patterns and trends. This study proposes a mathematical programming formulation and solution algorithm that considers multiple time intervals for the estimation of network-wide traffic states and calculation of the corresponding transition probabilities. The proposed solution enables the determination of sections of the …

Doing Business In America: A Jewish History, Purdue University Press

The Jewish Role in American Life: An Annual Review

American and Jewish historians have long shied away from the topic of Jews and business. Avoidance patterns grew in part from old, often negative stereotypes that linked Jews with money, and the perceived ease and regularity with which they found success with money, condemning Jews for their desires for wealth and their proclivities for turning a profit. A new, dauntless generation of historians, however, realizes that Jewish business has had and continues to have a profound impact on American culture and development, and patterns of immigrant Jewish exploration of business opportunities reflect internal, communal, Jewish-cultural structures and their relationship to …

Collision Avoidance Path Planning For Ships By Particle Swarm Optimization, Yu-Tao Kang, Wei-Jiong Chen, Da-Qi Zhu, Jin-Hui Wang, Qi-Miao Xie

Journal of Marine Science and Technology–Taiwan

Ship collision avoidance is a key consideration in maritime systems. Collision avoidance maneuvers depend on navigators’ experience and skill levels. Because both maritime traffic densities and average ship speeds are increasing, the times available for decision-making are decreasing, which elevates the risk of human errors in the collision avoidance process. To reduce the effect of human factors and efficiently prevent collisions between ships navigating in open water with effective visibility, a particle swarm optimization (PSO) algorithm can be used to plan ship paths. An improved ship domain dynamic model can assess collision risks in close-range encounters. Several marine traffic scenarios …

Pledges Of Faith: The Development Of Ancient Roman Business Law And Contemporary Applications, Devon Guanci

History & Classics Undergraduate Theses

It is no secret that the legacy of both the Roman Republic and Empire continue to influence Western culture and lifestyle today. In this thesis, I will specifically consider the development of Roman commercial and contract law. As Rome experienced continued expansion into the imperial age, commerce, use of contracts, and global trade worked to establish a robust economy in the empire. Thus, the established system of commercial law created a stable backbone that was necessary for the longevity of ancient Rome. While the modern United States is unlike Rome in many ways, many of the laws, as well as …

Skiing At Martin The Northern Pacific Stop At Stampede Pass, John W. Lundin

Works by Local Authors

Martin is a stop on the Northern Pacific Railroad at the east portal of its tunnel under Stampede Pass, going through the Cascade Mountains, named for the nearby Martin Creek. Since the 1920s, Northwest skiers took the Northern Pacific Railroad to Martin to take advantage of the deep snow that fell there. The story of skiing at Martin is virtually unknown these days, and Martin is one of the Lost Ski Areas of Washington.

The Future Of Innovation: How Libraries Support Entrepreneurs, Ilana Stonebraker, Heather A. Howard, Joe Collier, Saira Raza

Libraries Faculty and Staff Scholarship and Research

This paper highlights the ways that three different libraries are working to support entrepreneurs in their community: a public librarian connected with city government to support a small business development center; a librarian from a private university worked with social entrepreneurs that want to transform the world with business; a librarian from a large public land-grant works with entrepreneurs across the campus including business incubators and business competitions. The work these librarians do highlights the many ways libraries support entrepreneurs through collaboration, vision, and partnership.

Universities In Imperial Austria, 1848–1918: A Social History Of A Multilingual Space, Jan University Surman

Purdue University Press Books

Combining history of science and a history of universities with the new imperial history, Universities in Imperial Austria 1848–1918: A Social History of a Multilingual Space by Jan Surman analyzes the practice of scholarly migration and its lasting influence on the intellectual output in the Austrian part of the Habsburg Empire.

The Habsburg Empire and its successor states were home to developments that shaped Central Europe's scholarship well into the twentieth century. Universities became centers of both state- and nation-building, as well as of confessional resistance, placing scholars if not in conflict, then certainly at odds with the neutral international …

Hospitals are penalized for unnecessary readmissions (HRRP, 2018). In addition to the financial burden of readmissions, quality of life is decreased with readmission.

Context – Early or timely outpatient follow-up after hospitalization has been projected as a means of decreasing readmission rates.

Interventions – Integrating follow-up appointment to the current care transition - HUB process as a means in reducing readmission rates.

Measures & Results – Identified high-risk patients that need timely …

Corporate Social Responsibility To-Come: A Derridean Interruption Of Transparency, Robert Foschia

Electronic Theses and Dissertations

This study investigated the relation between rhetorics of transparency and organizational action. Digging into CSR literature from a philosophy of communication perspective, this project seeks to determine if corporate social responsibility delivers on the promises it makes of a better world.

Drawing on the work of Jacques Derrida, the research first lays out his often overlooked contribution to the philosophy of communication, and then moves towards possible applications in deconstructing the perceived benefits of CSR, particularly in its transparent nature. By looking at organizational life from the Triple Bottom Line, this dissertation peels back the underlying rhetoric of planet, people, …

Working Paper No. 28, Roots Of The American Labor Movement, Lillian Garcia

Working Papers in Economics

This inquiry seeks to establish that early developments in America’s workforce helped to shape the national labor movement that emerged at the end of the 19th Century. The first section discusses the changing social, economic, and legal landscapes from the colonial era to the Industrial Revolution. The second section examines the history of concerted action amongst the free and bound working classes leading up to 1842, when the case Commonwealth v. Hunt established the previously contested per se legality of labor combinations. The final section discusses developments in labor organization during the decades following Hunt, in which, amidst …

Kcnq1/Kcne1 Interaction In The Cardiac Iks Channel And Its Physiological Consequences, Jiajing Xu

McKelvey School of Engineering Graduate Student Theses & Dissertations

Dynamic conformational changes of ion channel proteins during activation gating determine their function as carriers of current. The relationship between these molecular movements and channel function over the physiological timescale of the action potential (AP) has not been fully established due to limitations of existing techniques. We constructed a library of possible cardiac IKs protein conformations and applied a combination of protein segmentation and energy linearization to study this relationship computationally. Simulations reproduced the effects of the beta-subunit (KCNE1) on the alpha-subunit (KCNQ1) dynamics and function, observed in experiments. Mechanistically, KCNE1 increased the probability of “visiting” conducting pore conformations on …

Multifunctional Nanocomposites Based On Bacterial Cellulose, Qisheng Jiang

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cellulose is biodegradable, renewable, and abundant in nature thus cellulose (or paper)-based products can be inexpensively produced and recycled. Among cellulosic materials, bacterial nanocellulose (BNC) draws a special research attention due to the inherent three-dimensional nanofibrous structure, excellent mechanical flexibility, high purity and well-defined surface chemistry, and cost-efficient, scalable and environment-friendly synthesis. BNC can be biosynthesized by Gluconacetobacter xylinus, which is the most characterized BNC producer among various microorganisms. BNC is composed of highly pure cellulose nanofibrils, produced from well-defined dextrose through biochemical steps and subsequent self-assembling of the secreted cellulose fibrils which has the dimension ranges from 25 to …

Literature In The World: A Critical Discourse Study Of World Literature Pedagogy, Elisa Cogbill-Seiders

UNLV Theses, Dissertations, Professional Papers, and Capstones

“Literature in the World” is a critical discourse analysis of world literature pedagogy in U.S. higher education. It investigates the ways discourse communities in higher education produce and shape the field of world literature. The dissertation begins by establishing and analyzing the generic conventions of university mission statements, finding they are primarily dominated by discourse on global learning. It follows with an analysis of world literature course descriptions from the same schools. World literature course descriptions alternatively replicate, resist, or subvert global learning discourses. The last chapter uses findings from the first two chapters to trace how university and instructor …
