Experimental Investigation Of Co2 Transport Through Combined Membrane Absorber And Regenerator, Nima Mohammadrasool Atbaei Nov 2016

Experimental Investigation Of Co2 Transport Through Combined Membrane Absorber And Regenerator, Nima Mohammadrasool Atbaei

Chemical and Petroleum Engineering Theses

Greenhouse gases such as carbon dioxide have been known to contribute significantly to global warming, which in turn has resulted in serious global environmental problems. Carbon dioxide is the main gaseous contaminant in the atmosphere, representing about 80% of greenhouse gases. It is reported that industry and power plants using fossil fuels such as coal-combustion power generators produce half of the CO2 emissions. These emissions create the need for low energy-consumption, and efficient technologies for the capture and removal of CO2 from gas mixtures produced by industrial sources.

Conventional gas absorption processes for the removal of CO2 …

Limiting Nutrient Contaminants From Agricultural Non-Point Sources: Nutrient Monitoring At Eku’S Meadowbrook Farm, Madison County, Kentucky, Walter S. Borowski, Jonathan M. Malzone

EKU Faculty and Staff Scholarship

Sources of contamination to U.S. waterways have largely shifted from industrial, point sources to agricultural and other non-point sources associated with common human activities. EKU’s Meadowbrook Farm explores best-practices in agriculture and animal husbandry that not only act to increase the efficiency of farm operations, but also to limit environmental effects such as the eutrophification of its neighboring watershed.

We recently started a collaboration with the Farm and the EKU Department of Agriculture, which are developing methods to sequester phosphorus and thus limit nutrient export to the adjacent Muddy Creek watershed. Our task is to quantify the amount of phosphorus …

Geosciences and Geological and Petroleum Engineering Faculty Research & Creative Works

To investigate the mechanisms for the initiation and early-stage evolution of the nonvolcanic southernmost segments of the East African Rift System (EARS), we installed and operated 35 broadband seismic stations across the Malawi and Luangwa rift zones over a 2 year period from mid-2012 to mid-2014. Stacking of over 1900 high-quality receiver functions provides the first regional-scale image of the 410 and 660 km seismic discontinuities bounding the mantle transition zone (MTZ) within the vicinity of the rift zones. When a 1-D standard Earth model is used for time-depth conversion, a normal MTZ thickness of 250 km is found beneath …


Creativity & Religion: A Self-Study Of Mormon Mindset In The Art Classroom, Shon Scot Feller Nov 2016

Creativity & Religion: A Self-Study Of Mormon Mindset In The Art Classroom, Shon Scot Feller

Theses and Dissertations

A high school art teacher investigates the relationship of his religious beliefs with his notions of what it means to be creative. This Mormon teacher examines his religious and experiential life through self-study, by drawing from autoethnographic and hermeneutic phenomenological strategies. He believes that everyone, including himself and his students, has a creative potential. He also analyzes how his Mormon religion affects his view of creativity and how creativity has affected his behavior as a Mormon. The conclusions he reaches uncover the need for balance between his creative self and his Mormon self and outlines several ways to merge these …

Traditional Vs. Blended: The Effect Of Instruction Methods On Sixth Grade Pre-Algebra Students’ Performance And Perceptions, Lynn Marie Spady Nov 2016

Traditional Vs. Blended: The Effect Of Instruction Methods On Sixth Grade Pre-Algebra Students’ Performance And Perceptions, Lynn Marie Spady

Student Work

This study examined sixth grade students’ math performance under two models of instruction: traditional and blended. Blended instruction requires face-to-face learning with an instructor, but allows students to do a portion of the work independently online. Traditional instruction takes place with an instructor present at all times. One area of interest in this study was the level of procedural knowledge acquired under the two different models of instruction. Results from three different assessments indicated no significant difference between the two groups of students. An additional area of interest was students’ preferences in teaching strategies in math and approaches to learning. …

Information Technology And Learning On-The-Job, James Bessen Nov 2016

Information Technology And Learning On-The-Job, James Bessen

Faculty Scholarship

Economists disagree how much technology raises demand for workers with pre-existing skills. But technology might affect wages another way: through skills learned on the job. Using instrumental variables on 9 panels of workers from 1989 to 2013, this paper estimates that workers who use information technology (IT) have wage growth that is about 2% greater than non-IT workers, all else equal, implying substantial learning. This effect persists over time, implying sustained productivity growth from IT. Also, it benefits workers both with and without college degrees. Because many more college-educated workers use IT, college wages grow faster, contributing to economic inequality.

Costs Of Doing Nothing: Economic Consequences Of Not Adapting To Sea Level Rise In The Hampton Roads Region, Greg Van Houtven, Brooks Depro, Daniel Lapidus, Justine Allpress, Benjamin Lord, Virginia Coastal Policy Center, William & Mary Law School Nov 2016

Costs Of Doing Nothing: Economic Consequences Of Not Adapting To Sea Level Rise In The Hampton Roads Region, Greg Van Houtven, Brooks Depro, Daniel Lapidus, Justine Allpress, Benjamin Lord, Virginia Coastal Policy Center, William & Mary Law School

Virginia Coastal Policy Center

October of 2016 brought Hurricane Matthew to coastal Virginia, providing once again an illustration of the vulnerability of the Hampton Roads region and economy to the threats and impacts of flooding and the role of sea level rise in those impacts. The hurricane prompted Virginia Governor Terry McAuliffe to state, “Climate change is real. Sea-level rise is happening. We’ve got to get into the game.” Indeed, sea level rise, combined with 14 to 17 inches of rain that fell in the region during the hurricane, damaged over 2,000 homes (many that were outside the flood zone and not covered by …


Unfolding Genus-2 Orthogonal Polyhedra With Linear Refinement, Mirela Damian, Erik Demaine, Robin Flatland, Joseph O'Rourke Nov 2016

Unfolding Genus-2 Orthogonal Polyhedra With Linear Refinement, Mirela Damian, Erik Demaine, Robin Flatland, Joseph O'Rourke

Mathematics Sciences: Faculty Publications

We show that every orthogonal polyhedron of genus g ≤ 2 can be unfolded without overlap while using only a linear number of orthogonal cuts (parallel to the polyhedron edges). This is the first result on unfolding general orthogonal polyhedra beyond genus- 0. Our unfolding algorithm relies on the existence of at most 2 special leaves in what we call the “unfolding tree” (which ties back to the genus), so unfolding polyhedra of genus 3 and beyond requires new techniques.

We consider the Erdős–Rényi random directed graph process, which is a stochastic process that starts with n vertices and no edges, and at each step adds one new directed edge chosen uniformly at random from the set of missing edges. Let (Formula presented.) be a graph with m edges obtained after m steps of this process. Each edge (Formula presented.) ((Formula presented.)) of (Formula presented.) independently chooses a color, taken uniformly at random from a given set of (Formula presented.) colors. We stop the process prematurely at time M when the following two events hold: (Formula presented.) has at most …

Ultra-Filtration Of Human Serum For Improved Quantitative Analysis Of Low Molecular Weight Biomarkers Using Atr-Ir Spectroscopy, Franck Bonnier, Helene Blasco, Clement Wasselet, Guillaume Brachet, Renaud Respaud, Luis Felipe Cs. Carvalho, Dominque Bertrand, Mathew J. Baker, Hugh Byrne, Igor Chourpa

Articles

Infrared spectroscopy is a reliable, rapid and cost effective characterisation technique, delivering a molecular finger print of the sample. It is expected that its sensitivity would enable detection of small chemical variations in biological samples associated with disease. ATR-IR is particularly suitable for liquid sample analysis and, although air drying is commonly performed before data collection, just a drop of human serum is enough for screening and early diagnosis. However, the dynamic range of constituent biochemical concentrations in the serum composition remains a limiting factor to the reliability of the technique. Using glucose as a model spike in human serum, …

Magnetization Reversal In Ferromagnetic Spirals Via Domain Wall Motion, Ryan D. Schumm, Andrew Kunz

Physics Faculty Research and Publications

Domain wall dynamics have been investigated in a variety of ferromagnetic nanostructures for potential applications in logic, sensing, and recording. We present a combination of analytic and simulated results describing the reliable field driven motion of a domain wall through the arms of a ferromagnetic spiral nanowire. The spiral geometry is capable of taking advantage of the benefits of both straight and circular wires. Measurements of the in-plane components of the spirals' magnetization can be used to determine the angular location of the domain wall, impacting the magnetoresistive applications dependent on the domain wall location. The spirals' magnetization components are …

Conformational States Of Cytochrome P450 Oxidoreductase Evaluated By Förster Resonance Energy Transfer Using Ultrafast Transient Absorption Spectroscopy, Elizaveta A. Kovrigina, Brian Pattengale, Chuanwu Xia, Azamat R. Galiakhmetov, Jier Huang, Jung Ja Kim, Evgenii L. Kovrigin

Chemistry Faculty Research and Publications

NADPH-cytochrome P450 oxidoreductase (CYPOR) was shown to undergo large conformational rearrangements in its functional cycle. Using a new Förster resonance energy transfer (FRET) approach based on femtosecond transient absorption spectroscopy (TA), we determined the donor–acceptor distance distribution in the reduced and oxidized states of CYPOR. The unmatched time resolution of TA allowed the quantitative assessment of the donor–acceptor FRET, indicating that CYPOR assumes a closed conformation in both reduced and oxidized states in the absence of the redox partner. The described ultrafast TA measurements of FRET with readily available red–infrared fluorescent labels open new opportunities for structural studies in chromophore-rich …


Smart Power Grid Synchronization With Fault Tolerant Nonlinear Estimation, Xin Wang, Edwin E. Yaz Nov 2016

Smart Power Grid Synchronization With Fault Tolerant Nonlinear Estimation, Xin Wang, Edwin E. Yaz

Electrical and Computer Engineering Faculty Research and Publications

Effective real-time state estimation is essential for smart grid synchronization, as electricity demand continues to grow, and renewable energy resources increase their penetration into the grid. In order to provide a more reliable state estimation technique to address the problem of bad data in the PMU-based power synchronization, this paper presents a novel nonlinear estimation framework to dynamically track frequency, voltage magnitudes and phase angles. Instead of directly analyzing in abc coordinate frame, symmetrical component transformation is employed to separate the positive, negative, and zero sequence networks. Then, Clarke's transformation is used to transform the sequence networks into the αβ …


The Mapmaker’S Dilemma In Evaluating High-End Inequality, Daniel Shaviro Nov 2016

The Mapmaker’S Dilemma In Evaluating High-End Inequality, Daniel Shaviro

University of Miami Law Review

The last thirty years have witnessed rising income and wealth concentration among the top 0.1% of the population, leading to intense political debate regarding how, if at all, policymakers should respond. Often, this debate emphasizes the tools of public economics, and in particular optimal income taxation. However, while these tools can help us in evaluating the issues raised by high-end inequality, their extreme reductionism—which, in other settings, often offers significant analytic payoffs—here proves to have serious drawbacks. This Article addresses what we do and don’t learn from the optimal income tax literature regarding high-end inequality, and what other inputs might …

We build on a recent photometric decomposition analysis of 7506 Galaxy and Mass Assembly (GAMA) survey galaxies to derive stellar mass function fits to individual spheroid and disc component populations down to a lower mass limit of log(M*/M⊙) = 8. We find that the spheroid/disc mass distributions for individual galaxy morphological types are well described by single Schechter function forms. We derive estimates of the total stellar mass densities in spheroids (ρspheroid = 1.24 ± 0.49 × 108 M⊙ Mpc −3h0.7) and discs (ρdisc = 1.20 ± 0.45 × 108 M⊙ Mpc −3h0.7), which translates to approximately 50 …

A Complex Systems Framework Approach Towards Multidisciplinary Tumor Boards, Rahul Salla, Robert Pahle, Ashish Amresh

Publications

Multidisciplinary tumor boards (MTBs) are universally recommended and have been used in treatment of late stage cancers. Tumor boards have the advantage of including all the stakeholders in the decision making process and improving quality of care, however several studies have pointed to their lack of efficiency and tend to be lackluster while not producing the desired benefits for the participants. In this paper we present the design of a web based immersive framework for collaborative decision making that has the potential to improve several inefficiencies in conducting tumor boards and improve overall clinical outcomes. We present the design of …

Climate, Soil And Land-Use Based Land Suitability Evaluation For Oil Palm Production In Ghana, Tiemen Rhebergen, Thomas Fairhurst, Shamie Zingore, Myles Fisher, Thomas Oberthür, Anthony Whitbread

All Peer-Reviewed Publications

In the past decade, oil palm (Elaeis guineensis Jacq.) has become the world's most important oil crop. The large demand for palm oil has resulted in a rapid expansion of oil palm cultivation across the globe. Because of the dwindling availability of land in Southeast Asia, most expansion of the industry is expected in Central and South America and sub-Saharan Africa, where land with suitable agro-ecological conditions is available. Using Ghana as a case study, a method for evaluating areas that are both suitable and available for oil palm production is presented. Our assessment used spatial data and GIS techniques, …


Multiplex Social Ecological Network Analysis Reveals How Social Changes Affect Community Robustness More Than Resource Depletion, Jacopo A. Baggio, Shauna B. Burnsilver, Alex Arenas, James S. Magdanz, Gary P. Kofinas, Manlio De Domenico Nov 2016

Multiplex Social Ecological Network Analysis Reveals How Social Changes Affect Community Robustness More Than Resource Depletion, Jacopo A. Baggio, Shauna B. Burnsilver, Alex Arenas, James S. Magdanz, Gary P. Kofinas, Manlio De Domenico

Environment and Society Faculty Publications

Network analysis provides a powerful tool to analyze complex influences of social and ecological structures on community and household dynamics. Most network studies of social–ecological systems use simple, undirected, unweighted networks. We analyze multiplex, directed, and weighted networks of subsistence food flows collected in three small indigenous communities in Arctic Alaska potentially facing substantial economic and ecological changes. Our analysis of plausible future scenarios suggests that changes to social relations and key households have greater effects on community robustness than changes to specific wild food resources.

The validity of statistical inference depends on proper randomization methods. However, even with proper randomization, we can have imbalanced with respect to important characteristics. In this paper, we introduce a method based on ranked auxiliary variables for treatment allocation in crossover designs using Latin squares models. We evaluate the improvement of the efficiency in treatment comparisons using the proposed method. Our simulation study reveals that our proposed method provides a more powerful test compared to simple randomization with the same sample size. The proposed method is illustrated by conducting an experiment to compare two different concentrations of titanium dioxide nanofiber …

Numerous investigations of the mature segments of the East African rift system (EARS) have significantly improved our understanding of the structure and processes associated with well-developed continental rifts. In contrast, knowledge of rifting processes at their early stage is still significantly limited. Here we present results from a teleseismic P-wave tomography investigation of the incipient Okavango rift zone (ORZ), which is located at the southwestern terminus of the EARS. P-wave relative travel-time residuals recorded by 17 recently deployed portable seismic stations were manually picked and inverted for three-dimensional upper-mantle and mantle transition-zone tomographic images beneath the ORZ and its adjacent …
