3-D Transient Hydraulic Tomography In Unconfined Aquifers With Fast Drainage Response, Michael Cardiff, Warren Barrash Dec 2011

3-D Transient Hydraulic Tomography In Unconfined Aquifers With Fast Drainage Response, Michael Cardiff, Warren Barrash

CGISS Publications and Presentations

We investigate, through numerical experiments, the viability of three-dimensional transient hydraulic tomography (3DTHT) for identifying the spatial distribution of groundwater flow parameters (primarily, hydraulic conductivity K) in permeable, unconfined aquifers. To invert the large amount of transient data collected from 3DTHT surveys, we utilize an iterative geostatistical inversion strategy in which outer iterations progressively increase the number of data points fitted and inner iterations solve the quasi-linear geostatistical formulas of Kitanidis. In order to base our numerical experiments around realistic scenarios, we utilize pumping rates, geometries, and test lengths similar to those attainable during 3DTHT field campaigns performed at …

Roman: Routing And Opportunistic Management Of Airborne Networks, Hemanth Meka, Lekshmi Manian Chidambaram, Sanjay K. Madria, Mark Linderman, Mohan Kumar, Sharma Chakravarthy Dec 2011

Roman: Routing And Opportunistic Management Of Airborne Networks, Hemanth Meka, Lekshmi Manian Chidambaram, Sanjay K. Madria, Mark Linderman, Mohan Kumar, Sharma Chakravarthy

Computer Science Faculty Research & Creative Works

Most of the routing and replication algorithms for Mobile Peer to Peer (M-P2P) networks assume the network to be large and therefore, the architecture and algorithms are designed to be scalable. These algorithms however may not perform well with limited number of nodes in a network such as of UAVs. Thus, it is better to design algorithms to increase the efficiency of a small network if scalability is no longer an issue. for such small networks, we design and simulate an effective two layered graph-based routing algorithm using store/forward concept. We also take into account UAVs orientation and configuration of …

Identification And Efficient Estimation Of The Natural Direct Effect Among The Untreated, Samuel D. Lendle, Mark J. Van Der Laan Dec 2011

Identification And Efficient Estimation Of The Natural Direct Effect Among The Untreated, Samuel D. Lendle, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

The natural direct effect (NDE), or the effect of an exposure on an outcome if an intermediate variable was set to the level it would have been in the absence of the exposure, is often of interest to investigators. In general, the statistical parameter associated with the NDE is difficult to estimate in the non-parametric model, particularly when the intermediate variable is continuous or high dimensional. In this paper we introduce a new causal parameter called the natural direct effect among the untreated, discus identifiability assumptions, and show that this new parameter is equivalent to the NDE in a randomized …

Effect Of Transverse Surface Roughness On The Performance Of Hydromagnetic Squeeze Film Between Conducting Truncated Conical Plates, Pragna Amratlal Vadher, Gunamani Deheri, Rakesh Manilal Patel Dec 2011

Effect Of Transverse Surface Roughness On The Performance Of Hydromagnetic Squeeze Film Between Conducting Truncated Conical Plates, Pragna Amratlal Vadher, Gunamani Deheri, Rakesh Manilal Patel

Journal of Marine Science and Technology–Taiwan

An attempt has been made to study and analyze the behavior of a hydromagnetic squeeze film between conducting porous transversely rough truncated conical plates. The associated Reynolds' equation is solved with appropriate boundary conditions to investigate the behavior of performance characteristics. The results indicate that the performance of the bearing system gets enhanced vis-à-vis a bearing system working with a conventional lubricant. This article reveals that the negative effect induced by porosity and standard deviation can be overcome completely by the positive effect of the magnetization parameter and conductivities by choosing suitable aspect ratio and the semi-vertical angle in the …

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 …

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 …

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 …

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 …

"If You Build It, They Will Come": The Positive Economic Impacts Of Nfl Stadiums In Their Surrounding Cities, Mary C. Ewen Dec 2011

"If You Build It, They Will Come": The Positive Economic Impacts Of Nfl Stadiums In Their Surrounding Cities, Mary C. Ewen

Honors Theses

As with most sports, the incredible emotion that comes with dedicated fans radiates throughout the cities in which these teams reside. The positive economic impact that NFL stadiums have on their surrounding cities is the driving factor behind the creation of these sports power houses. NFL franchises increase tourism, and create an economic stimulus within the community that makes hosting an NFL franchise within a city extremely appealing. Studies show that there may be an incentive to creating these colossal entities. However, these outcomes are not always considered to be because of direct influences the stadiums exude, and in some …

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 …

A 2d Chaos-Based Visual Encryption Scheme For Clinical Eeg Signals, Chin-Feng Lin, Boa-Shun Wang Dec 2011

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 …

A General Model For Continuous Noninvasive Pulmonary Artery Pressure Estimation, Robert Anthony Smith Dec 2011

A General Model For Continuous Noninvasive Pulmonary Artery Pressure Estimation, Robert Anthony Smith

Theses and Dissertations

Elevated pulmonary artery pressure (PAP) is a significant healthcare risk. Continuous monitoring for patients with elevated PAP is crucial for effective treatment, yet the most accurate method is invasive and expensive, and cannot be performed repeatedly. Noninvasive methods exist but are inaccurate, expensive, and cannot be used for continuous monitoring. We present a machine learning model based on heart sounds that estimates pulmonary artery pressure with enough accuracy to exclude an invasive diagnostic operation, allowing for consistent monitoring of heart condition in suspect patients without the cost and risk of invasive monitoring. We conduct a greedy search through 38 possible …

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 …

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.
