Quantifying Ceramic Proppant Transport In Complex Fracture Networks, Vivekvardhan Reddy Kesireddy

Masters Theses

"Water fracs have become an essential part of unconventional reservoirs to create deeper fracture networks. Proppant transport in water fracs is challenging in terms of fluids ability to carry the proppant deeper into these fracture networks. This experimental study investigates the impact of the flow rates, fracture widths and complexity controlling the ability of proppant to flow into complex fracture networks. This research attempts to nullify the knowledge gap in understanding width heterogeneity in primary and secondary fractures. This study speaks for settling pattern and proppant transport through a slot flow model with a unique approach to understand stage wise …

Overview Of Co₂ Leakage Problems And Sealants For Co₂ Leakage Remediation, Shudai Peng

Masters Theses

"Excessive Carbon Dioxide (CO₂) emission has become a serious issue and caused lots of environmental problems. Carbon Capture and Storage (CCS) program has been developed to reduce the CO₂ content in the atmosphere. CO₂ storage has been targeted mainly on depleted oil or gas reservoirs and deep saline aquifers. However, leakage could occur through wellbores, cap rocks, formation faults, and fractures during and after CO₂ injection. To minimize the risk, different types of sealants have been investigated to prevent CO₂ leaks. The aim of this thesis is to provide a comprehensive review of the materials which could be used as …

Development And Implementation Of Star Tracker Based Attitude Determination, Casey Grant Smith

Masters Theses

"As interest in nanosatellites grows within the university community, the demand for inexpensive, space-grade hardware grows as well. Star trackers can be a luxury item for some spacecraft and therefore are often not considered due to their cost. Ideally, a star tracker could be built using inexpensive parts so long as the software is available. Unlike many other attitude determination instruments, star trackers are renowned for their high accuracy, yielding accurate and precise attitude estimates. However, development of this software can be overwhelming for the university settling, especially when multiple missions are on hand. If these instruments were readily available …

Multiple Security Domain Nondeducibility Air Traffic Surveillance Systems, Anusha Thudimilla

Masters Theses

"Traditional security models partition the security universe into two distinct and completely separate worlds: high and low level. However, this partition is absolute and complete. The partition of security domains into high and low is too simplistic for more complex cyber-physical systems (CPS). Absolute divisions are conceptually clean, but they do not reflect the real world. Security partitions often overlap, frequently provide for the high level to have complete access to the low level, and are more complex than an impervious wall. The traditional models that handle situations where the security domains are complex or the threat space is ill …

Characterizing Groundwater Flow At Fort Leonard Wood Using Universal Cokriging With Trend Removal, Rachel Mae Uetrecht

Masters Theses

"Groundwater elevation interpolation is necessary for the prediction of groundwater flow direction and contaminant transport. Kriging is a geostatistical tool commonly used to interpolate groundwater elevation. Kriging requires a relatively large number of monitoring wells at the site of interest. The variogram model is a crucial element to the kriging equations. The variogram modelling process is an iterative procedure that is often very time consuming. This study presents a literature based approach that provides a point of departure for the variogram modelling process as well as other kriging parameters. A literature database is developed in order to provide insight and …

Evaluation Of Preformed Particle Gel As A Diverting Agent For Acidizing, Bo Wei

Masters Theses

"Preformed particle gels (PPGs) have been developed and successfully used to improve conformance in heterogeneous reservoirs. However, no research has been reported to show their potential diverting applications in acidizing because of their unknown performance in this process. This work targets on evaluating the potential of PPGs to be used as diverting agents and factors influencing the diverting performance.

The swelling properties of three types of PPGs (PPG #1, #2, and #3) were first studied in brine and acid, including the swelling kinetics and equilibrium, PPG strength, and deswelling performance. Effects of different brine concentration, acid concentration, and temperature were …

Sparse Emission Source Microscopy For Rapid Emission Source Imaging, Ling Zhang

Masters Theses

"In Paper I, Sparse Emission Source Microscopy (ESM) methodology will be introduced and discussed for the localization of major EMI radiation sources in complex and large systems. Traditional ESM method takes abundant and uniformly-distributed scanning points on the scanning plane using a robotic system, which can provide high-quality source images but consumes too much time. This section presents a sparse and nonuniform sampling technique for ESM, which is more time-efficient in identifying major radiation sources, even though the image quality is sacrificed. The feasibility of sparse sampling is mathematically proved, and it is shown that increasing number of points increases …

Lexicography In-Your-Face: The Active Semantics Of Pastaza Quichua Ideophones, Janis B. Nuckolls, Tod D. Swanson, Diana Shelton, Alexander Rice, Sarah Hatton

Faculty Publications

English:

We argue that a multimodal approach to defining a depictive class of words called ‘ideophones’ by linguists is essential for grasping their meanings. Our argument for this approach is based on the formal properties of Pastaza Quichua ideophones, which set them apart from the non-ideophonic lexicon, and on the cultural assumptions brought by speakers to their use. We analyze deficiencies in past attempts to define this language’s ideophones, which have used only audio data. We offer, instead, an audiovisual corpus which we call an ‘antidictionary’, because it defines words not with other words, but with clips featuring actual contexts …

Agent-Based Modelling Of The Relationships Among Kinship, Residence, And Exchange, James R. Allison

Faculty Publications

In the North American Southwest, archaeological research has documented ceramic exchange networks in which spatially proximate households in consumer communities have greatly varying amounts of imported pottery. This paper uses agent-based modelling to gain insight into the processes responsible for these distributions. The agent-based model used here tracks kinship ties among agents representing individuals who give birth, marry, co-reside with spouses, and exchange things in a virtual landscape filled with small settlements of up to a few hundred individuals. Exchange of goods in the model flows through the kinship networks. The results suggest that the differential distribution of goods among …

Sourcing Basalt From The Santiago Quarry In Chihuahua, Mexico Using Xrf, Michael T. Searcy, Todd Pitezel, Eric Christiansen

Faculty Publications

During survey in 2013, we identified the only known vesicular basalt quarry in the Casas Grandes region in northwestern Chihuahua, Mexico. Using XRF, we analyzed basalt from the Santiago Quarry and compared the results to the chemical characterization of formal tools (mostly mano and metate fragments) recovered at the site of Paquimé in order to determine if this quarry was one of the sources exploited by prehistoric stoneworkers during the Medio period (AD 1200–1450).

The Latter-Day Saint Reimaging Of “The Breath Of Life” (Genesis 2:7), Dana M. Pike

Faculty Publications

The creation and flood accounts in Genesis in the Hebrew Bible (the Christian Old Testament) contain variations on a phrase commonly translated “the breath of life.” This phrase additionally occurs in some uniquely Latter-day Saint materials relating to creation. After overviewing and analyzing this phrase and its meaning in the Bible, this paper then examines the occurrences of the phrase “the breath of life” in important early Latter-day Saint texts.1 The purpose of this study is to illustrate and explain how and why many Latter-day Saints have come to often employ the phrase “the breath of life,” transforming its traditional …

Birthright Citizenship Under Attack: How Dominican Nationality Laws May Be The Future Of U.S. Exclusion, Ediberto Roman, Ernesto Sagas

American University Law Review

Attacks on birthright citizenship periodically emerge in the United States, particularly during presidential election cycles. Indeed, blaming immigrants for the country's woes is a common strategy for conservative politicians, and the campaign leading up to the 2016 presidential election was not an exception. Several of the Republican presidential candidates raised the issue, with President Donald Trump making it the hallmark of his immigration reform platform. Trump promised that, if elected, his administration would "end birthright citizenship."

In the Dominican Republic, ending birthright citizenship and curbing immigration are now enshrined into law, resulting from a significant constitutional redefinition of Dominican citizenship …

Controlled Manipulation Of Floating Objects On Deformed Fluid Interfaces And Conditions For Stable Equilibria, Jose M. Carballo, Qi Ni, Jose Vasquez, Nathan B. Crane

Faculty Publications

At the millimeter scale, interactions between floating and semi-immersed objects are significant. The local curvature of the interface is modified by the weight/buoyancy forces of floating objects, and by the surface properties of semi-immersed objects. The curvature changes generate attractive (or repulsive) interactions between floating parts, and semi-immersed objects. This work demonstrates how electrowetting can manipulate these interactions in order to position, align, assemble and transport parts attached to the fluid interface. This demonstrates one way in which fluid interfaces can provide an alternative to standard pick and place technology for part positioning/assembly. Typically, the part/rod forces are purely attractive …

Investigating Composite Action At Ultimate For Commercial Sandwich Panel Composite Connectors, Salam Al-Rubaye, Taylor J. Sorensen, Marc Maguire

Faculty Publications

To achieve full or partial-composite action in prestressed concrete sandwich panel walls, the engineer must obtain a percent composite action from a connector manufacturer, making some engineers uncomfortable. Engineers are dependent upon the recommendations given by the connector manufacturers to establish their designs. This project tested six full-scale sandwich panel walls to evaluate the percent composite action of various connectors and compare the results to those provided by the composite connector manufacturers. This study concluded that the reported degrees of composite action from each manufacturer are considered conservative in all instances for the connectors tested in this paper. Additionally, the …

Developing A General Methodology For Evaluating Composite Action In Insulated Wall Panels, Taylor Sorensen

Faculty Publications

Precast concrete sandwich wall panels (PCSWPs) have been in use for over 60 years. They provide a very efficient building envelope for many buildings. Characteristic PCSWPs comprise an outer and inner layer (or wythe) of concrete separated by an insulating material. To use all of the material as efficiently as possible, the layers are attached by connectors which penetrate through the insulating layer and are embedded in either concrete wythe. These connectors make it possible for both layers of the wall to work together when resisting loads. The connectors are made out of plastic, or FRP, to prevent heat transfer …

Risk Factors Associated With Poor Health Outcomes For Children Under The Age Of 5 With Moderate Acute Malnutrition In Rural Fagita Lekoma District, Awi Zone, Amhara, Ethiopia, 2016, W/Amilak Adamu, Dube Jara, Mulunesh Alemayehu, Sahai Burrowes

Background: Left untreated, moderate acute malnutrition (MAM) in children can lead to severe acute malnutrition, stunting, developmental delays, and death. Despite recent progress the prevalence of malnutrition remains high throughout Ethiopia. The ability to make accurate prognoses and develop effective treatment strategies for children with MAM is currently limited and, as result, a significant proportion of children with MAM fail to recover even with treatment. We seek to address this limitation by assessing the risk factors for poor outcomes among children under the age of 5 with MAM in a rural area of Ethiopia’s Amhara Region. This region is …

On a public, coeducational research university located in the Pacific Northwest, a concurrent triangulated mixed method research design was implemented to investigate cultural factors with preferred learning and teaching styles of Chinese international students along with what corroborative descriptions these students provide as effective learning experiences in American college classrooms.

The study brought attention to Chinese international students’ differing cultural values from the previous literature understanding, it supported previous …

Evaluating The Attitudes Of Preservice Teachers Toward Multicultural Competence, Angela D. Marshall

Theses and Dissertations

Changes in the ethnicity of the student population across the nation necessitated a change in teacher education curricula. This explanatory, sequential, mixed-method study examined how a group of preservice teachers viewed the importance of multicultural competence before and after student teaching. Specifically, an evaluation of preservice teachers’ attitudes about their own multicultural preparedness was made prior to and after being given full responsibility for an ethnically diverse classroom.

The study employed quantitative and qualitative measures to assess preservice teachers’ levels of multicultural competence as well as their awareness of self-perceptions of multicultural competence that contribute to attitudes toward teaching an …

Effects Of A Peer-Tutoring System Utilizing Students With Emotional Behavioral Disorders As Tutors And Students With Intellectual Disabilities As Tutees, Vicki Koslin Howell

Theses and Dissertations

High school students with intellectual disabilities often find appropriate ways and times to socialize with their peers. In self-contained settings, students are often limited to interacting with only those within the classroom. In addition, students with emotional behavioral disorders often have deficits in social domains and in self-esteem. Improving socializations of students with disabilities has always been a concern of both parents and teachers. Peer-mediated learning has been a proven effective way to instruct students with disabilities. Placing a student with an emotional behavioral disorder in the position of a peer tutor allows them to feel more secure in their …

Course Quality And Hosting Platforms: Implications For Massively Open Online Course (Mooc) Design And Delivery, Rita Diane Schmallegger

Theses and Dissertations

Massive open online courses (MOOCs) began as an experiment in connectivist learning in 2008 (Downes, 2012). While the number of MOOCs offered has risen, as has the number of universities offering MOOCs (Brown, Costello, Donkon, & Giolla-Mhichill, 2015), perceptions of the quality of MOOCs have been mixed (Bali, 2014; Peterson, 2014). From a perspective of Merrill’s first principles of instruction (2013), this qualitative study examined MOOC delivery platforms to determine what learning platforms and what specific characteristics may best promote and sustain MOOC quality. MOOCs selected for this study include those offered in English, open to anyone with Internet access, …
