The Modeling the Epidemiologic Transition Study (METS) is a cohort study designed to assess the association between physical activity levels and relative weight, weight gain and diabetes and cardiovascular disease risk in five population-based samples at different stages of economic …

Comparing Historical And Implied Volatility For A Silver Electronically Traded Fund Between Months Of High And Low Returns, Jacob G. Downey

Honors Theses

Silver as a commodity is used in many different industrial applications as well as in jewelry. Silver is five times scarcer than gold (Stamey, Class Notes, 2011) is at this point and is becoming more and more popular with investors. Many investors instead of buying physical silver have looked to invest in the Silver ETF. An ETF is an Exchange Traded Fund, and is a way to trade a commodity like a stock. A price varies in proportion to the commodity, so as Silver moves so does SLV (Silver ETF). In this paper, the Silver ETE chosen was iShares Silver …

Multimessenger Astronomy: Modeling Gravitational And Electromagnetic Radiation From A Stellar Binary System, Kevin Kern

Honors Theses

Our Solar System is one of roughly 100 billion other stars that make up the Milky Way Galaxy. Two-thirds of all stars are paired off, forming a gravitational bond between one another. Such systems are known as stellar binaries. Although these binaries are prevalent there is much yet to be learned about their formation, evolution, and interactions. The approach taken in this thesis is to produce simulated data representing the expected measurements that an observational astronomer would collect. Specifically, we have simulated the data from an eclipsing binary light curve, spectroscopic velocity curve, and the gravitational wave times series form …

Photocatalytic Activity Of Zinc Oxide Thin Films Prepared By Dc Sputter Deposition And Thermal Oxidation, Robert Louder

Honors Theses

Zinc oxide (ZnO) is a wide-bandgap semiconductor with a broad range of applications, such as photocatalysis. The photocatalytic properties of ZnO result from the highly oxidizing holes and reducing electrons that are induced on the ZnO surface by ultraviolet (UV) light. The efficiency of electron-hole pair formation is therefore critical for photocatalysis, and thus the optical quality of the films in the UV region is of critical importance. ZnO thin films have been fabricated using DC sputter deposition of Zn-metal films followed by thermal oxidation at different temperatures (300, 600, and 900°C). Characterization of the optical properties of the resulting …

Streamwise Dynamics Controlled Jet Spreading, Mixing And Physical Source Of The Vortices, Amalendu Sau, Robert R. Hwang

Journal of Marine Science and Technology–Taiwan

Within the framework of the present investigation we perform Direct Numerical Simulations to study the role of streamwise dynamics in the jet spreading and mixing, and provide a clear understanding about the source of these important vortices in two-step rectangular sudden expansion flows. The present setup is designed to generate higher mass entrainment, and the system generated passive forcing provided the necessary impetus for the sustained growth/evolution of the streamwise vertices, which played the key role in the mixing enhancement. On the other hand, by suitably placing two tiny rectangular ‘tabs’ on the inlet channel walls, the nature of growth …

Is Islam The Solution?: The Muslim Brotherhood And The Search For An Islamic Democracy In Egypt, Erica Devine

History & Classics Undergraduate Theses

Since the removal of President Mubarak in 2011, the role of the Muslim Brotherhood as a political force within Egypt has grown exponentially. These events have called into question the role the Muslim Brotherhood will play in the creation of a new government in Egypt. During the 1970s and 1980s, the Brotherhood underwent a gradual transformation of its ideology in the direction of democracy and political participation.The influence of such ideologues as Hasan al-Banna, Hasan Isma‘il al-Hudaybi, Umar al-Tilmisani, and Yusef al-Qaradawi provided the foundation for this transition and spurred the movement towards the blending of civil and religious agendas. …

Co-Crystallization And Polymorphism Of Naturally Occurring Peptide Derivatives, Kevin Crowley

Honors Theses

Carnosine is a dipeptide compound that is found in many dietary supplements and food products. Carnosine has many functions in the body, such as alleviating oxidative stress on tissues by acting as an antioxidant compound. Carnosine, therefore, has important anti-aging properties. Carnosine is also capable of forming protective sequestration structures around heavy metal ions; this process of chelating metals ions in solutions is very beneficial for maintaining the well-being of cells in the body. Thus, carnosine could be useful in pharmaceutical products for creating anti-aging drugs that would reduce tissue stress and promote a healthy cellular environment. I attempted to …

Selectivity Of Prey Capture Based On Prey Size In The Venus Fly Trap (Dionaea Muscipula Ellis), Jessica Humenik

Honors Theses

Venus fly traps (Dionaea muscipula Ellis) are carnivorous plants that live in nutrient poor soils and must digest insects to supplement their diets. When a Venus fly trap captures an insect, the plant's traps do not fully close for several minutes, which may allow small prey to escape. It would be beneficial for the plant to consume a large, nutrient-rich prey item as opposed to a small prey item. We tested the hypothesis that Venus fly traps select larger prey by offering plants small and large crickets. A Kruskal-Wallis test and Wilcoxon signed rank test were used to test significance …

Lesson Not Learned: Deepwater Horizon Research And Media Coverage Exposes Gaps In Knowledge And Risky Protocol Within The Oil Industry, Lauren Haller

Honors Theses

An insatiable thirst for oil has led poorly coordinated, risk-prone megasystems deeper into the ocean in search of new oil reserves. Profit-driven agendas at the corporate level have a top-down effect within these megasystems. Cost-cutting and risk-downplaying leaves the field employees unprepared to handle emergencies. A series of costly mistakes led to the 2010 BP Deepwater Horizon oil spill, which caused extensive damage to an already fragile ecosystem in the Gulf of Mexico. The wealth and political influence of the oil industry overpowers lax regulatory agencies and legislation-even though media and research has exposed frustrating parallels between the Deepwater Horizon …

Perceptions Of Walt Disney World: Antecedents To Return Visits, Tiffani A. Cosson

Honors Theses

Walt Disney World is an extremely popular tourist destination that attracts millions of visitors each year. Scholars have researched Walt Disney World and there are many different written articles on the subject, however there are very few that delve deep enough into the subject to generate quantitative data about visitors rather than only opinions about the parks. Due to its popularity and prominence in America, it is important to determine which demographic segment prefers to visit Walt Disney World. This can be used for both the parks themselves as a marketing tool, and consumers as well by knowing when the …

The Smartest "Guise" In The Room: Why America Is Doomed To Repeat An Enron-Like Scandal, Shayne Reddington

Honors Theses

There is no question that Enron has brought change to the landscape surrounding business practices both domestically and globally. After the Emon Scandal occurred, Congress passed a very controversial and groundbreaking legislative act known as the Sarbanes-Oxley Act as a means of stopping the conditions that made this widespread scandal possible. There are several reasons why another Emon-type Scandal is prone to repeat itself in the near future. One of the reasons is that Sarbanes-Oxley is not the perfect bill. Although the controversial Sarbanes-Oxley is a valiant effort to reform the environment that fostered Enron, there are major gaps and …

Computer Science Faculty Research & Creative Works

Intelligent argumentation based collaborative decision-making system assists stakeholders in a decision-making group to assess various alternatives under different criterion based on the argumentation. a performance score of each alternative under every criterion in Multi-Criteria Decision Making (MCDM) is represented in a decision matrix and it denotes satisfaction of the criteria by that alternative. the process of determining the performance scores of alternatives in a decision matrix for criterion could be controversial sometimes because of the subjective nature of criterion. We developed a framework for acquiring performance scores in a decision matrix for multi-criteria decision making using an intelligent argumentation and …

A Union Of Negatives: Ayatollah Khomeini And The Mobilization Of Dissent In The Iranian Revolution Of 1979, Nicholas G. Sumski

History & Classics Undergraduate Theses

The Islamic Revolution of 1979 eradicated half a century of Westernization in Iran and installed Ayatollah Khomeini as the leader of Iran’s new Islamic Republic. However, the revolutionary forces were not strongly unified under Khomeini’s radical Islamic vision. Indeed, many facets of the opposition simply desired moderate political reforms to increase democratic participation in the government and opposed the imposition of a government directed under the auspices of Islam. By the late 1970s, though, these various moderate revolutionaries realized that the only legitimate means to overthrow the reign of the American-supported Shah, Mohammad Reza Pahlavi, would be to join the …

Scramjet Isolator Modeling And Control, John R. Hutzel

Theses and Dissertations

The scramjet isolator is a duct in which pressure increases from the inlet to the combustor via a shock train. The shock train leading edge (LE) location must be controlled in an operational scramjet. A LE location measurement algorithm, dynamic model, and control algorithm were developed and validated with 500 frame per second (FPS) shadowgraph images in this research. The test apparatus consisted of a direct connect cold-flow high-speed wind tunnel with an adjustable ramp mounted in the tunnel floor. Ramp adjustments changed the tunnel cross-sectional area which changed the tunnel back pressure and LE location. Wall-mounted pressure transducers and …

A 2d Chaos-Based Visual Encryption Scheme For Clinical Eeg Signals, Chin-Feng Lin, Boa-Shun Wang

Journal of Marine Science and Technology–Taiwan

In this paper, we have developed a two-dimensional (2D) chaos-based encryption scheme that can be applied to signals with transmission bit errors in clinical electroencephalography (EEG) and mobile telemedicine. As opposed to one-dimensional (1D) chaos-based encryption, the proposed 2D schemes uses the concept of parallel processing to increase the encryption speed. An essential feature of the proposed scheme is that signals mapping of a 2D chaotic scrambler and a permutation scheme are used to obtain clinical EEG information that requires high-level encryption. Simulation results show that when the correct deciphering parameters are inputted, EEG signals with a transmission bit error …

Beyond Alliances: The Jewish Role In Reshaping The Racial Landscape Of Southern California, George J. Sanchez

The Jewish Role in American Life: An Annual Review

This volume focuses on the special role that Jews played in reshaping the racial landscape of southern California in the twentieth century. Rather than considering this issue in terms of broad analyses of organizations or communities, each contribution instead approaches it by examining the activity of a single Jewish individual, and how he or she navigated the social terrain of a changing southern California. In particular, this volume is one of the first to take seriously the unique racial/ethnic makeup of southern California for Jewish activism, with a particular focus on the relationship between Jews and Mexican Americans in the …

The Use Of Various Failure Criteria As Applied To High Speed Wear, David A. Huber

Theses and Dissertations

This research has been aimed at developing methods to predict mechanical wear of sliding bodies at high velocities. Specifically, wear of test sled slippers at the Holloman High Speed Test Track at Holloman AFB, NM, is being considered. Developing a numerical model to represent the velocity range achieved at the test track is infeasible, so numerical modeling techniques must be adopted. Previous research has made use of finite element codes to simulate the high velocity sliding event. However, the extreme velocities at the test track can create numerical errors in the finite element codes. To avoid the numerical errors, an …

Elementary Teachers’ Mental Models Of Engineering Design Processes: A Comparison Of Two Communities Of Practice, Ann Piening Mcmahon

Dissertations

Educating K-12 students in the processes of design engineering is gaining popularity in public schools. Several states have adopted standards for engineering design despite the fact that no common agreement exists on what should be included in the K-12 engineering design process. Furthermore, little pre-service and in-service professional development exists that will prepare teachers to teach a design process that is fundamentally different from the science teaching process found in typical public schools. This study provides a glimpse into what teachers think happens in engineering design compared to articulated best practices in engineering design.
