Integrating Climate Information Into Water Resource Decision-Making In South Florida, Jessica A. Bolson

Open Access Dissertations

Water resource decision making in South Florida is characterized by complexity. Factors including climate variability and change, population, land use, and shifting water demands contribute to this complexity. Integrated approaches are suggested as mechanisms to observe and manage complex management challenges, but the practical role of integrated models in environmental decision-making has not been thoroughly evaluated. This research evaluates the potential role for an integrated water model by applying an end-to-end research design in the context of South Florida water management stakeholders. Scenarios for future drivers of water demand and the integrated system dynamics water model, the SFIWM, which were …

Chemical And Acoustic Emission Evaluation Studies Of Concrete Bridge In Marine Environment, Alexander Boudewijn Suma

Open Access Dissertations

A field investigation of the Fair Isle Bridge, Miami, Florida consists of a nondestructive evaluation program including physical and acoustic emission (AE) assessment. The bridge is situated in a marine environment and its deck consists of PC and RC sections. Chemical evaluation is performed prior to strengthening with CFRP laminates and consists of visual inspection, carbonation, pH evaluation, chloride content, and steel corrosion detection by half-cell potential. After repair, three additional physical assessments are performed: crack mapping, thermography, and AE. These combined techniques provide sufficient information to create layered maps to evaluate the condition of the bridge structure. Within the …

Building Transnational Media Spaces: Immigrant Journalism In South Florida, Moses A. Shumow

Open Access Dissertations

Since the election of Hugo Chávez in 1999 and the subsequent rapid growth of Venezuelan immigration to the United States, there has been an explosion of Venezuelan community media in South Florida. While focused on local issues, the mediated communication being produced and distributed among members of this community remains distinctly transnational in scope, informed primarily by events taking place in Venezuela as the country is being transformed politically, socially, and economically under the controversial leadership of President Hugo Chávez. This study presents an empirical, qualitative investigation into the practices of Venezuelan media producers in South Florida through a series …

The Use Of Building Information Modeling In Generating Hard Bid Estimates, Peter Samuel Jensen

Theses and Dissertations

Building Information Modeling has provided many benefits to the architectural, engineering, construction and facilities management communities. Many studies have been done to validate the asserted benefits, including benefits to the field of estimating. The studies on estimating are currently limited to the realm of conceptual estimates, and have only treated detailed estimates in the abstract. The purpose of this study was to determine how BIM was being used by companies in a hard bid, or detailed estimate scenario. The research team used the Deseret Towers housing project at Brigham Young University as the basis for the research. A building information …

Eit, Slow Light, And Sealing Methods For Embedding Rubidium Into The Arrow System, Katherine Barnett Hurd

Theses and Dissertations

Light-matter interactions are fundamentally based on the quantum mechanical principles that govern photons, electrons and other fundamental particles. One very interesting phenomenon within all of light-matter interactions is Electromagnetically Induced Transparency(EIT). This phenomenon causes an otherwise absorbing atomic transition to stop absorbing through quantum mechanical interference of probability wave functions. Corresponding to that change in absorption, will be a sudden, large change in the index of refraction. This change in the index of refraction leads to another phenomenon in which the group velocity of light can be slowed down dramatically. In the past, many researchers have been able to achieve …

A Comparative Verification Of Forecasts From Two Operational Solar Wind Models, Donald C. Norquist, Warner C. Meeks

Mechanical and Aerospace Engineering Faculty Research & Creative Works

The solar wind (SW) and interplanetary magnetic field (IMF) have a significant influence on the near‐Earth space environment. In this study we evaluate and compare forecasts from two models that predict SW and IMF conditions: the Hakamada‐Akasofu‐Fry (HAF) version 2, operational at the Air Force Weather Agency, and Wang‐Sheeley‐Arge (WSA) version 1.6, executed routinely at the Space Weather Prediction Center. SW speed (V_sw) and IMF polarity (Bpol) forecasts at L1 were compared with Wind and Advanced Composition Explorer satellite observations. Verification statistics were computed by study year and forecast day. Results revealed that both models’ mean Vsw are …

A Reusable Persistence Framework For Replicating Empirical Studies On Data From Open Source Repositories, Scott Bong-Soo Chun

Theses and Dissertations

Empirical research is inexact and error-prone leading researchers to agree that replication of experiments is a necessary step to validating empirical results. Unfortunately, replicating experiments requires substantial investments in manpower and time. These resource requirements can be reduced by incorporating component reuse when building tools for empirical experimentation. Bokeo is an initiative within the Sequoia Lab of the BYU Computer Science Department to develop a platform to assist in the empirical study of software engineering. The i3Persistence Framework is a component of Bokeo which enables researchers to easily build and rapidly deploy tools for empirical experiments by providing an easy-to-use …

Joining Polycrystalline Cubic Boron Nitride And Tungsten Carbide By Partial Transient Liquid Phase Bonding, Grant O. Cook Iii

Theses and Dissertations

Friction stir welding (FSW) of steel is often performed with an insert made of polycrystalline cubic boron nitride (PCBN). Specifically, MS80 is a grade of PCBN made by Smith MegaDiamond that has been optimized for the FSW process. The PCBN insert is attached to a tungsten carbide (WC) shank by a compression fitting. However, FSW tools manufactured by this method inevitably fail by fracture in the PCBN. Permanently bonding PCBN to WC would likely solve the fracturing problem and increase the life of PCBN FSW tools to be economically viable. Partial transient liquid phase (PTLP) bonding, a process used to …

Large Scale Application Of Vibration Sensors For Fan Monitoring At Commercial Layer Hen Houses, Ji-Qin Ni, Yan Chen, Claude A. Diehl, Albert J. Heber, Bill W. Bogan, Li-Long Chai

School of Agricultural & Biological Engineering Faculty Publications

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application has not yet been evaluated. This paper presents long-term performance results of this vibration sensor at two large commercial layer houses. Vibration sensors were installed on 164 fans of 130 cm diameter to continuously monitor the fan on/off status for two years. The …

An Evaluation Of Multiple Choice Test Questions Deliberately Designed To Include Multiple Correct Answers, Kim Scott Thayn

Theses and Dissertations

The multiple-choice test question is a popular item format used for tests ranging from classroom assessments to professional licensure exams. The popularity of this format stems from its administration and scoring efficiencies. The most common multiple-choice format consists of a stem that presents a problem to be solved accompanied by a single correct answer and two, three, or four incorrect answers. A well-constructed item using this format can result in a high quality assessment of an examinee's knowledge, skills and abilities. However, for some complex, higher-order knowledge, skills and abilities, a single correct answer is often insufficient. Test developers tend …

Development Of A Rigid Body Computational Model For Investigation Of Wrist Biomechanics, Benjamin Majors

Theses and Dissertations

The wrist is one of the most complex joints in the human body. As such, the wrist joint is difficult to model due to the number of bones involved and its intricate soft tissue interactions. Many studies have attempted modeling the wrist previously; however, the majority of these studies simplify the joint into two-dimensions or idealized mechanical joints to reduce the complexity of the simulation. While these approaches still yield valuable information, the omission of a third-dimension or geometry defined movements limits the models’ usefulness in predicting joint function under non-idealized conditions. Therefore, the goal of this study was to …
