Modeled And Observed Dynamical Characteristics Of Convective Mass Transport, Mariusz Starzec

Theses and Dissertations

Convection can rapidly and efficiently transport polluted boundary layer air to the upper troposphere and lower stratosphere, thereby influencing the chemical composition and distribution of greenhouse gases in the atmosphere. Whether mass detrains into the upper troposphere or lower stratosphere has differing impacts on the radiative budget and hence, on climate. Currently, there have been only a few observing platforms capable of studying convective mass transport, which have significant limitations and are frequently restricted to field campaigns resulting in a small number of case studies. Outside of these case studies, little is known about the actual heights that convection detrains …

Digital Rock Analysis On Berea Sandstone And An Eor Study On Middle Bakken, Barco N. Yolo

Theses and Dissertations

Oil production from tight formations such as the Bakken Formation has experienced a boom in the last decade with recent breakthroughs in horizontal drilling and hydraulic fracturing. However, despite the technological progress, the oil recovery is still less than 10 percent, leaving a considerable amount of potentially recoverable oil. While miscible flooding is well understood in the conventional reservoir, it is not fully explored in unconventional reservoirs. Therefore, it is essential to evaluate different enhanced oil recovery techniques potential in tight shale plays.

In this thesis, the research studies CO2 and ethane interactions with oil at reservoir conditions through laboratory …

Pricing Of Games As A Service: An Analytical Model For Interactive Digital Services With Hedonic Properties, Tayfun Keskin

Information Systems Faculty Publications

This study explores optimal pricing strategies in games and other interactive digital goods under incomplete information, when bundling is an option. Drawing from research on the pricing of information goods, we propose a pattern of optimal pricing strategies in which hedonic characteristics affect the utility of interactive digital goods and services. This is a new approach to games, to treat them as a service to determine pricing strategies. Findings reveal that there is an optimal pricing solution for firms in the gaming industry. This finding holds both in bundling and non-bundling cases. Utilizing analytical modeling methodology, we propose pricing-inspired business …

Intensity Inhomogeneity Correction Of Sd-Oct Data Using Macular Flatspace, Andrew Lang, Aaron Carass, Bruno M. Jedynak, Sharon D. Solomon, Peter A. Calabresi, Jerry L. Prince

Mathematics and Statistics Faculty Publications and Presentations

Images of the retina acquired using optical coherence tomography (OCT) often suffer from intensity inhomogeneity problems that degrade both the quality of the images and the performance of automated algorithms utilized to measure structural changes. This intensity variation has many causes, including off-axis acquisition, signal attenuation, multi-frame averaging, and vignetting, making it difficult to correct the data in a fundamental way. This paper presents a method for inhomogeneity correction by acting to reduce the variability of intensities within each layer. In particular, the N3 algorithm, which is popular in neuroimage analysis, is adapted to work for OCT data. N3 works …

On The Girth And Diameter Of Generalized Johnson Graphs, Louis Anthony Agong, Carmen Amarra, John Caughman, Ari J. Herman, Taiyo S. Terada

Mathematics and Statistics Faculty Publications and Presentations

Let v > k > i be non-negative integers. The generalized Johnson graph, J(v,k,i), is the graph whose vertices are the k-subsets of a v-set, where vertices A and B are adjacent whenever |A∩B|= i. In this article, we derive general formulas for the girth and diameter of J(v,k,i). Additionally, we provide a formula for the distance between any two vertices A and B in terms of the cardinality of their intersection.

Bootcmatch: A Software Package For Bootstrap Amg Based On Graphweighted Matching, Pasqua D'Ambra, Salvatore Filipone, Panayot S. Vassilevski

The adaptive AMG presented is meant to handle general symmetric and positive definite (SPD) sparse linear systems, without assuming any a priori information of the problem and its origin; the …

Clustering And Multifacility Location With Constraints Via Distance Function Penalty Methods And Dc Programming, Mau Nam Nguyen, Thai An Nguyen, Sam Reynolds, Tuyen Tran

Mathematics and Statistics Faculty Publications and Presentations

This paper is a continuation of our effort in using mathematical optimization involving DC programming in clustering and multifacility location. We study a penalty method based on distance functions and apply it particularly to a number of problems in clustering and multifacility location in which the centers to be found must lie in some given set constraints. We also provide different numerical examples to test our method.

Rick, Morty, And Absurdism: The Millennial Allure Of Dark Humor, Kim Koltun

The Forum: Journal of History

The purpose of this paper is to investigate the millennial generation’s appeal to dark and absurdist forms of humor, using the show Rick and Morty as a primary example. I first establish my definition of Absurdism—based on Nagel and Camus—and how Rick and Morty qualifies as an Absurdist work. I then go on to outline the popularity of the show among millennial audiences and explore its allure. There are three important sociological contexts to this explanation: the contrast between upbringing and reality, expedited modernity, and rapidly changing information structures. These set the stage for a distinctive style of humor that …

Assessment Of Spatiotemporal Fusion Algorithms For Planet And Worldview Images, Chiman Kwan, Xiaolin Zhu, Feng Gao, Bryan Chou, Daniel Perez, Jinag Li, Yuzhong Shen, Krzysztof Koperski, Giovanni Marchisio

Electrical & Computer Engineering Faculty Publications

Although Worldview-2 (WV) images (non-pansharpened) have 2-m resolution, the re-visit times for the same areas may be seven days or more. In contrast, Planet images are collected using small satellites that can cover the whole Earth almost daily. However, the resolution of Planet images is 3.125 m. It would be ideal to fuse these two satellites images to generate high spatial resolution (2 m) and high temporal resolution (1 or 2 days) images for applications such as damage assessment, border monitoring, etc. that require quick decisions. In this paper, we evaluate three approaches to fusing Worldview (WV) and Planet images. …

Core And Uncore Joint Frequency Scaling Strategy, Vaibhav Sundriyal, Masha Sosonkina, Bryce Westheimer, Mark Gordon

Electrical & Computer Engineering Faculty Publications

Energy-proportional computing is one of the foremost constraints in the design of next generation exascale systems. These systems must have a very high FLOP-per-watt ratio to be sustainable, which requires tremendous improvements in power efficiency for modern computing systems. This paper focuses on the processor—as still the biggest contributor to the power usage—by considering both its core and uncore power subsystems. The uncore describes those processor functions that are not handled by the core, such as L3 cache and on-chip interconnect, and contributes significantly to the total system power. The uncore frequency scaling (UFS) capability has been available to the …

Square-Root Consider Filters With Hyperbolic Householder Reflections, James S. Mccabe, Kyle J. De Mars

Mechanical and Aerospace Engineering Faculty Research & Creative Works

Maintaining positive definiteness of a filter's error covariance estimate is of paramount importance to any stable and reliable estimation scheme. Two widely used methods for protecting a filter from loss of positive-definiteness are that of consider filtering and square-root filtering. Despite their widespread use in estimation applications, a filtering methodology that combines the two techniques has yet to be presented in a unified, streamlined architecture. This paper develops a new approach to square-root filtering using hyperbolic Householder reflections. A specialization of the method is considered to permit computationally efficient applications, and a numerical example pertaining to a ballistic reentry is …

A mixture of [Emim][EtSO4]-HAN is a potential propellant suitable in a multi-mode chemical-electric microtube-electrospray micro propulsion system. This paper reports experimental mass spectrum results for this liquid when electro sprayed in a 50 μm capillary emitter. Mass spectra from 0-600 amu were obtained over a variety of angles and flow rates from 2 pL/sec to 3 nL/sec in both cation and anion extraction mode. Effects of flow rate and angular orientation on the spectra agree well with literature. Results show at least three of the four monomer species are emitted, along with numerous other species, some of which have been …

The Library In The Mountains And The Writing On The Wall : Fragmented Memories And Cultural Amnesia In Ursula K. Le Guin, Erin Michelle Roll

Theses, Dissertations and Culminating Projects

Memory, especially its loss, plays a prominent role in the work of Ursula K. Le Guin (b. 1929). The Telling (2000) and Voices (2006), two of Le Guin’s most recent works, go into great detail on what happens when a memory is lost or destroyed, usually under duress. The former, the last book in Le Guin’s Hainish cycle, deals with a goal to preserve books and learning from a regime that has made it a misguided goal to eradicate all elements of past culture in an effort to modernize the country. In the latter, part of Le Guin’s Annals of …

This qualitative research study explored speech-language pathologists’ (SLP) perceptions regarding their potential to influence patient adherence to dysphagia recommendations. Five SLPs holding the CCC-SLP were interviewed in an open-ended format, and the transcriptions of the interviews were the data for this study. The SLP interviews provided a glimpse into SLP interpretations of patients’ fears, concerns, and comprehension of their dysphagia and the recommendations they were given. The themes identified within the data were SLP education for patient and family, respect for patient decisions, SLP understanding of barriers to patient adherence to dysphagia recommendations, family buy-in and practical support, perpetuation of …

Energy-Rich Mesopelagic Fishes Revealed As A Critical Prey Resource For A Deep-Diving Predator Using Quantitative Fatty Acid Signature Analysis, Chandra Goetsch, Melinda G. Conners, Suzanne M. Budge, Yoko Mitani, William A. Walker, Jeffrey F. Bromaghin, Samantha E. Simmons, Colleen Reichmuth, Daniel P. Costa

Biological Sciences Faculty Publications

Understanding the diet of deep-diving predators can provide essential insight to the trophic structure of the mesopelagic ecosystem. Comprehensive population-level diet estimates are exceptionally difficult to obtain for elusive marine predators due to the logistical challenges involved in observing their feeding behavior and collecting samples for traditional stomach content or fecal analyses. We used quantitative fatty acid signature analysis (QFASA) to estimate the diet composition of a wide-ranging mesopelagic predator, the northern elephant seal (Mirounga angustirostris), across five years. To implement QFASA, we first compiled a library of prey fatty acid (FA) profiles from the mesopelagic eastern North Pacific. Given …

Recognizing Addictive Disorders Through Transdiagnostic Assessment, Meagan M. Carr

Master's Theses and Doctoral Dissertations

Some evidence suggests high rates of comorbidity between substance and other related addictive disorders. However, few self-report instruments adopt a transdiagnostic approach, which would be best positioned to answer questions about comorbidity as well as other related phenomenon, such as discontinuation of one type of behavior and initiation of another. The current work aimed to develop a measure that screened for seven types of potentially addictive behavior: alcohol use, drug use, tobacco use, gambling, binge eating, hypersexual behavior, and excessive video game playing. Data were collected at three time-points to develop a large pool of possible items, establish the initial …

Bilateral Deficit: A Comparison Between Upper-Body And Lower-Body Maximal Strength, James Lee Ramsey

Master's Theses and Doctoral Dissertations

Purpose: The study’s primary purpose was to determine if maximal unilateral strength is greater than maximal bilateral strength for the leg press and vertical dumbbell press exercises. The secondary purpose was to determine if blood glucose levels differ between the unilateral and bilateral conditions for the leg press exercise. Methods: Thirty college-aged volunteers reported on two separate occasions, 72 hours apart, for maximal strength testing. Blood glucose was obtained before and after strength testing for the leg press exercise. A paired samples t-test was conducted to determine significance (p < .05). Results: Participants were significantly stronger for the bilateral leg press; however, no significant differences were observed for the vertical dumbbell press exercise. No significant differences were observed in plasma blood glucose for the leg press exercise. Conclusion: Participants did not display a bilateral lateral deficit, which may have been a result of their resistance training prior to the study.

Students' Understanding About Clinical Research And Their Willingness To Participate In Clinical Trials, Shashikiran Pathakamudi

Master's Theses and Doctoral Dissertations

Adolescents and young adults remain underrepresented in clinical trials. Knowledge and perceptions related to clinical research usually determine willingness to participate. During the spring of 2016, an in-class paper survey was conducted to determine whether providing a brief introduction to clinical research would affect the willingness of undergraduate students from the College of Arts and Sciences and the College of Technology at Eastern Michigan University to participate in clinical trials. Some participants received information on clinical research through a short paragraph, and some received no new information, which differentiated the “active” group from the “placebo” group. Overall, both groups provided …

Mechanically Driven Pendula For Instructional Laboratories, R. M. Pacheco

Master's Theses and Doctoral Dissertations

I present a new, low-cost approach to observing driven resonance with simple and physical pendula. I mount a pendulum on a dynamics cart that is made to oscillate along a horizontal line by a stepper motor and micro-controller. The pendulum pivot therefore has a position that varies sinusoidally with time with a constant, adjustable frequency. I designed and constructed the experiment to be easily implemented into any physics lab. I tested the apparatus and observed driven resonance for both types of pendula. All of the measured resonant frequencies I determined using the apparatus had percent uncertainties under 4% and all …

An Approximation To A Bayesian Detection Statistic For Continuous Gravitational Waves., John J. Bero Iv

Theses

This work concerns Bayesian detection statistics in targeted searches for continuous gravitational waves (GWs). The parameter space for continuous GWs can be divided into 2 groups: amplitude parameters which control the signal strength and phase-evolution parameters which determine its time evolution. A common issue in these searches is dealing with these amplitude parameters which do not affect the phase evolution of the system. The F-statistic maximizes the likelihood function of the data analytically over these parameters, while the B-statistic marginalizes over them. The B-statistic, while potentially more powerful and capable of incorporating astrophysical priors, is not used because of the …
