Harmonic Decomposition By Hht On Regular Waves Propagating Over A Rectangular Submerged Obstacle Upon A Fluidized Bed, Yung-Lung Chen, Shiaw-Yih Tzang, Shan-Hwei Ou

Journal of Marine Science and Technology–Taiwan

The experimental measurements of surface waves over a submerged rectangular obstacle upon a sandy bed reported by Tzang et al. (2008) have further been analyzed in detail by Hilbert-Huang transform (HHT). The harmonic components of regular waves at 5 sites in the vicinity of the obstacle are decomposed into the intrinsic mode functions (IMFs) by the ensemble empirical mode decomposition (EEMD) with postprocessing scheme using masking signal EMD (MSEMD). The results of Hilbert spectrum of waves derived by the HHT illustrate that considerable decay of harmonic amplitude occurs at all 5 sites when the sandy bed have been fluidized but …

Influences Of Discharge Reductions On Salt Water Intrusion And Residual Circulation In Danshuei River, Wen-Cheng Liu, Wei-Bo Chen, Ming-Hsi Hsu Dec 2011

Influences Of Discharge Reductions On Salt Water Intrusion And Residual Circulation In Danshuei River, Wen-Cheng Liu, Wei-Bo Chen, Ming-Hsi Hsu

Journal of Marine Science and Technology–Taiwan

A three-dimensional, unstructured grid, hydrodynamic model was established and applied to study the salt water intrusion and residual circulation in the Danshuei River estuarine system of northern Taiwan. The construction of two reservoirs (i.e. Shihmen Reservoir and Feitsui Reservoir) and water diversion in the upper reaches of the river system significantly reduces the freshwater inflow. The changes had contributed farther to the intrusion of tidal flow and salt water in the upstream direction. The model was validated with available hydrographic data measured in 2001 then used to probe the change in salt water intrusion as a result of reservoir construction. …

Dynamic Coupling Of Multi-Phase Fluids With A Moving Obstacle, Tso-Ren Wu, Chih-Jung Huang, Mei-Hui Chuang, Chung-Yue Wang, Chia-Ren Chu Dec 2011

Dynamic Coupling Of Multi-Phase Fluids With A Moving Obstacle, Tso-Ren Wu, Chih-Jung Huang, Mei-Hui Chuang, Chung-Yue Wang, Chia-Ren Chu

Journal of Marine Science and Technology–Taiwan

In this paper, we present a two-way coupled moving solid algorithm with discrete element method (DEM) to simulate dynamic fluid-solid interaction. This model allows obstacles moving in the multi-phase fluids to generate realistic motion for both the fluids and obstacles. We discretize the NavierStokes equation using finite volume method (FVM) for the fluid part. The volume-of-fluid (VOF) method is used to track the fluid-fluid and fluid-solid interfaces. This algorithm is useful in the fields of Engineering and Earth Sciences, such as structure collapse and landslide generated tsunamis. Examples of landslide tsunami and floating cubes are demonstrated using the algorithm.

The Method Of Fundemental Solutions For The Multi-Dimensional Wave Equations, Meng-Huang Gu, Chia-Ming Fan, Der-Liang Young Dec 2011

The Method Of Fundemental Solutions For The Multi-Dimensional Wave Equations, Meng-Huang Gu, Chia-Ming Fan, Der-Liang Young

Journal of Marine Science and Technology–Taiwan

In this paper, a meshless method is developed for solving multi-dimensional wave equations. The proposed method is based on the method of particular solution (MPS), the method of fundamental solutions (MFS) and the Houbolt finite difference (FD) method. The wave equation is considered as a Poisson-type equation with the time-dependent source term. The Houbolt method is applied to avoid the difficult problems for dealing with the initial conditions in forming the linear algebra system. The works of space discretization are dependent on the method of particular solution and the method of fundamental solutions. There are three numerical examples considered in …

Comparing Historical And Implied Volatility For A Silver Electronically Traded Fund Between Months Of High And Low Returns, Jacob G. Downey Dec 2011

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 …

Remixing Business Models: Technology And The Future Of The Modern Music Industry, Ryan Brown Dec 2011

Remixing Business Models: Technology And The Future Of The Modern Music Industry, Ryan Brown

Honors Theses

The music industry has undergone significant changes throughout the past few decades. The primary basis of these changes is technology, which has impacted everything from finding artists to distributing music. However, record labels have been slow to adapt to these changes, which has led to serious problems such as illegal music downloading. Illegal downloading, also known as "music piracy," has radically changed the entire business and distribution structures within the music industry. Although lawsuits and other strategies have been undertaken to attempt to combat this particular issue, technology will continue to affect the music industry for the foreseeable future. Advances …

Multimessenger Astronomy: Modeling Gravitational And Electromagnetic Radiation From A Stellar Binary System, Kevin Kern Dec 2011

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 Dec 2011

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 …

Mechanism Of G Protein Beta-Gamma Assembly Mediated By Phosducin-Like Protein 1, Chun Wan Jeffrey Lai Dec 2011

Mechanism Of G Protein Beta-Gamma Assembly Mediated By Phosducin-Like Protein 1, Chun Wan Jeffrey Lai

Theses and Dissertations

G-protein coupled receptor signaling (GPCR) is essential for regulating a large variety of hormonal, sensory and neuronal processes in eukaryotic cells. Because the regulation of these physiological responses is critical, GPCR signaling pathways are carefully controlled at different levels within the cascade. Phosducin-like protein 1 (PhLP1) can bind the G protein βγ dimer and participate in GPCR signaling. Recent evidence has supported the concept that PhLP1 can serve as a co-chaperone of the eukaryotic cytosolic chaperonin complex CCT/TRiC to mediate G βγ assembly. Although a general mechanism of PhLP1-mediated G βγ assembly has been postulated, many of the details about …

Hydrological Parameter Estimations From A Conservative Tracer Test With Variable-Density Effects At The Boise Hydrogeophysical Research Site, B. Dafflon, Warren Barrash, Michael Cardiff, T. C. Johnson Dec 2011

Hydrological Parameter Estimations From A Conservative Tracer Test With Variable-Density Effects At The Boise Hydrogeophysical Research Site, B. Dafflon, Warren Barrash, Michael Cardiff, T. C. Johnson

CGISS Publications and Presentations

Reliable predictions of groundwater flow and solute transport require an estimation of the detailed distribution of the parameters (e.g., hydraulic conductivity, effective porosity) controlling these processes. However, such parameters are difficult to estimate because of the inaccessibility and complexity of the subsurface. In this regard, developments in parameter estimation techniques and investigations of field experiments are still challenging and necessary to improve our understanding and the prediction of hydrological processes. Here we analyze a conservative tracer test conducted at the Boise Hydrogeophysical Research Site in 2001 in a heterogeneous unconfined fluvial aquifer. Some relevant characteristics of this test include: variable-density …

Streamwise Dynamics Controlled Jet Spreading, Mixing And Physical Source Of The Vortices, Amalendu Sau, Robert R. Hwang Dec 2011

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 Dec 2011

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 Dec 2011

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 …

Freedom In Education: The Movement To Educate The Freedmen In The Pee Dee Region During Reconstruction, Aliyyah Willis Dec 2011

Freedom In Education: The Movement To Educate The Freedmen In The Pee Dee Region During Reconstruction, Aliyyah Willis

Honors Theses

The current scholarship on the education of the freed slaves in the South during Reconstruction is not so much one of differing points of view, but of specialization within the broader topic. Most of this scholarship focuses on the Southern region as a whole, rather than limiting the scope to just one state or smaller geographic area. Instead of arguing for or against a particular point of view, today's historians are focusing on one part of the larger topic to analyze. Whether studying the people themselves and their motivations, the teachers who educated them, or the system of education that …

Effects Of Menstruation On Women's Likeliness To Forgive, Brittany K. Gaillard Dec 2011

Effects Of Menstruation On Women's Likeliness To Forgive, Brittany K. Gaillard

Honors Theses

The effect the secretion and ovulation phases of the menstrual cycle has on forgiveness was examined in this study. It was hypothesized that women in either phase of their menstrual cycle would be less likely to forgive than those not in either phase of their menstrual cycle. Participants (N = 146) completed three questionnaires, one measuring their likeliness to forgive, one measuring their forgiveness of others, self, and situations, and the last collecting demographic information and information about their periods. The results showed no significant difference in woman's likeliness to forgive when experiencing a period and when not experiencing a …

Lesson Not Learned: Deepwater Horizon Research And Media Coverage Exposes Gaps In Knowledge And Risky Protocol Within The Oil Industry, Lauren Haller Dec 2011

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 …

Lagrange's Theory Of Analytical Functions And His Ideal Of Purity Of Method, Giovanni Ferraro, Marco Panza Dec 2011

Lagrange's Theory Of Analytical Functions And His Ideal Of Purity Of Method, Giovanni Ferraro, Marco Panza

MPP Published Research

We reconstruct essential features of Lagrange’s theory of analytical functions by exhibiting its structure and basic assumptions, as well as its main shortcomings. We explain Lagrange’s notions of function and algebraic quantity, and we concentrate on power-series expansions, on the algorithm for derivative functions, and the remainder theorem—especially on the role this theorem has in solving geometric and mechanical problems. We thus aim to provide a better understanding of Enlightenment mathematics and to show that the foundations of mathematics did not, for Lagrange, concern the solidity of its ultimate bases, but rather purity of method—the generality and internal organization of …

Age Predicted Heart Rate Max Equations In College-Aged Students, Jessica Benchley Dec 2011

Age Predicted Heart Rate Max Equations In College-Aged Students, Jessica Benchley

Honors Theses

Many clinicians use heart rate to tell how fit an individual is and how healthy they are. They can prescribe exercise based on heart rate and other medical conditions to help clients get better through exercise. Instead of running a client through a graded exercise test each time there is a problem, it would be much more effective to find an accurate equation to predict a max heart rate value and prescribe exercise using that value. The purpose of this experiment is to see which equation tends to predict the most accurate max heart after.

Perceptions Of Walt Disney World: Antecedents To Return Visits, Tiffani A. Cosson Dec 2011

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 …

An Analysis Of The Dietary Behaviors Of Coastal Carolina University's Ncaa Division I Student-Athletes, Alyssa Markowitz

Honors Theses

It is common knowledge that practice is the key to becoming better at something. This theory holds true with almost anything, from tying shoelaces to becoming a professional athlete. Elite athletes say that what has made them reach the top in their sports today is an incredible amount of dedication to repeatedly practicing their skills. As competition in sports becomes fiercer and starts at an increasingly younger age, practicing gains emphasis, but this is not the only aspect of achieving optimal performance that is extremely important. There is another factor that plays into how well one performs that is not …
