Unsupervised-Learning Assisted Artificial Neural Network For Optimization, Varun Kote

Mechanical & Aerospace Engineering Theses & Dissertations

Innovations in computer technology made way for Computational Fluid Dynamics (CFD) into engineering, which supported the development of new designs by reducing the cost and time by lowering the dependency on experimentation. There is a further need to make the process of development more efficient. One such technology is Artificial Intelligence. In this thesis, we explore the application of Artificial Intelligence (AI) in CFD and how it can improve the process of development.

AI is used as a buzz word for the mechanism which can learn by itself and make the decision accordingly. Machine learning (ML) is a subset of …

Effects Of High-Carbohydrate Versus Mixed-Macronutrient Meals On Soccer Physiology And Performance, Jaison Lee Wynne

Human Movement Studies & Special Education Theses & Dissertations

The purpose of the study was to measure the effects of an acute pre-competition high-carbohydrate (HCHO) meal versus a mixed-macronutrient (MM) meal on physiology, perceptual responses, and performance in 15 division I female collegiate soccer players. Being there are conjectural advantages to pre-exercise meals higher in fiber, fat, and protein, this study was conducted to evaluate the physiological and perceptual effects of pre-competition MM meals. This study used a randomized, investigator-blinded, crossover design involving two dietary interventions – HCHO and MM meals – that were consumed four hours prior to two separate intra-squad soccer scrimmages. Assessments included running metrics via …

A Design Of Inductive Coupling Wireless Power Transfer System For Electric Vehicle Applications, Sarika Reddy Daida

Electrical & Computer Engineering Theses & Dissertations

This research focuses on the study of using an inductive-coupled Wireless Power Transfer (WPT) system for electric vehicle charging applications in Medium Voltage DC (MVDC) power networks. Implementing WPT in Electric Vehicles (EVs) can provide a convenient alternative charging option, versus static charging in a station that would take hours. Also, it can prevent the potential of electrocution hazards that might occur due to the usage of physical medium like wires in EV charging. Even though inductive coupling has been applied in some applications of WPT, it is still not efficient enough to transfer high power at the kilowatts level …

Examining Trait Mindfulness As A Moderator Of The Mediating Relationship Between Social Anxiety, Coping Motives, And Substance-Related Consequences, Cody A. Raeder

Psychology Theses & Dissertations

The present research examined the mediating relationship between social anxiety, drinking to cope with social anxiety, and alcohol-related consequences. Additionally, this study examined the mediating relationship between social anxiety, using cannabis to cope with social anxiety and cannabis-related consequences. Furthermore, this study examined whether or not trait mindfulness exhibited a moderating effect on both of these mediation relationships which have been previously observed in the literature. The study consisted of students recruited through the psychology research participant pool at a mid-sized southeastern university. Two data sets were created based on type of substance use (alcohol or cannabis). The majority of …

"...Make Them Disappear With A Piece Of Paper": Understanding The Lived Realities Of Federally Unrecognized Indigenous Women In The Southeast, Brian A. Pitman

Sociology & Criminal Justice Theses & Dissertations

Indigenous women experience some of the highest rates of violence and negative health outcomes of any racial/ethnic group yet are largely ignored in social science research. This dissertation explores the lived realities of Indigenous women who are members of federally unrecognized nations and how their tribal membership impacts their experiences with a variety of criminal justice and social issues. Unrecognized nations do not have access to potential benefits, opportunities, and legitimacy that comes with federal recognition thereby creating an additional intersection to consider for some Indigenous women. Essentially, federal recognition policies seek to place further constraints on Indigenous identity, while …

Modulation Of Biological Responses To 2 Ns Electrical Stimuli By Field Reversal, Esin B. Sözer, P. Thomas Vernier

Bioelectrics Publications

Nanosecond bipolar pulse cancellation, a recently discovered Phenomenon, is modulation of the effects of a unipolar electric pulse exposure by a second pulse of opposite polarity. This attenuation of biological response by reversal of the electric field direction has been reported with pulse durations from 60 ns to 900 ns for a wide range of endpoints, and it is not observed with conventional electroporation pulses of much longer duration (> 100 mu s) where pulses are additive regardless of polarity. The most plausible proposed mechanisms involve the field-driven migration of ions to and from the membrane interface (accelerated membrane discharge). …

Protocol Measuring Horizontal Gene Transfer From Algae To Non-Photosynthetic Organisms, James Weifu Lee

Chemistry & Biochemistry Faculty Publications

Horizontal gene transfer (HGT) is a natural process for an organism to transfer genetic material to another organism that is a completely different species, for example, from a blue-green alga to a non-photosynthetic bacterium. The phenomenon of HGT is not only of an interest to the science of molecular genetics and biology, but also to the biosafety issue of genetic engineering. The novel protocol reported here for the first time teaches how to measure HGT from a genetically engineered (GE) blue-green alga (gene donor) to wild-type E. coli (recipient). This novel protocol can be used to measure HGT frequency for …

Hacking The Extended Mind: The Security Implications Of The New Metaphysics, Robin L. Zebrowski

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Computer security expert Paul Syverson has argued that there is a computer security equivalent of gaslighting: where a clever adversary could convince some system that some component that is not really a part of the system is in fact a part of the system. If non-biological items from our environments (or even pieces of our environments themselves) can be part of our minds (the standard Extended Mind hypothesis, EM), they are therefore part of our selves, and therefore subject to Syverson’s worry about boundary in a way that has not been explored before. If some version of EM holds, then …

Big Data And The Reference Class Problem. What Can We Legitimately Infer About Individuals?, Catherine Greene

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Big data increasingly enables prediction of the behaviour and characteristics of individuals. This is ethically concerning on privacy grounds. However, this article discusses other reasons for concern. These predictions usually rely on generalisations about what certain sorts of people tend to do. Generalisations of this sort are often under scrutiny in legal cases, where, for example, lawyers argue that people with prior convictions are more likely to be guilty of the crime they are currently on trial for. This article applies criteria for distinguishing acceptable from unacceptable generalisations in legal cases to a number of big data examples. It argues …

What To Do When Privacy Is Gone, James Brusseau

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Today’s ethics of privacy is largely dedicated to defending personal information from big data technologies. This essay goes in the other direction. It considers the struggle to be lost, and explores two strategies for living after privacy is gone. First, total exposure embraces privacy’s decline, and then contributes to the process with transparency. All personal information is shared without reservation. The resulting ethics is explored through a big data version of Robert Nozick’s Experience Machine thought experiment. Second, transient existence responds to privacy’s loss by ceaselessly generating new personal identities, which translates into constantly producing temporarily unviolated private information. The …

Human Supremacy As Posthuman Risk, Daniel Estrada

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Human supremacy is the widely held view that human interests ought to be privileged over other interests as a matter of public policy. Posthumanism is an historical and cultural situation characterized by a critical reevaluation of anthropocentrist theory and practice. This paper draws on Rosi Braidotti’s critical posthumanism and the critique of ideal theory in Charles Mills and Serene Khader to address the use of human supremacist rhetoric in AI ethics and policy discussions, particularly in the work of Joanna Bryson. This analysis leads to identifying a set of risks posed by human supremacist policy in a posthuman context, specifically …

Difference Between Algorithmic Processing And The Process Of Lifeworld (Lebenswelt), Domenico Schneider

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

The following article compares the temporality of the life-world with the digital processing. The temporality of the life-world is determined to be stretched and spontaneous. The temporality of the digital is given by discrete step-by-step points of time. Most ethical issues can be traced back to a mismatch of these two ways of processing. This creates a foundation for the ethics of the digital processing. Methodologically, phenomenological considerations are merged with media-philosophical considerations in the article.

A Metacognitive Approach To Trust And A Case Study: Artificial Agency, Ioan Muntean

Computer Ethics - Philosophical Enquiry (CEPE) Proceedings

Trust is defined as a belief of a human H (`the trustor') about the ability of an agent A (the `trustee') to perform future action(s). We adopt here dispositionalism and internalism about trust: H trusts A iff A has some internal dispositions as competences. The dispositional competences of A are high-level metacognitive requirements, in the line of a naturalized virtue epistemology. (Sosa, Carter) We advance a Bayesian model of two (i) confidence in the decision and (ii) model uncertainty. To trust A, H demands A to be self-assertive about confidence and able to self-correct its own models. In the Bayesian …

Coupling Metaproteomics With Taxonomy To Determine Responses Of Bacterioplankton To Organic Perturbations In The Western Arctic Ocean, Molly P. Mikan

OES Theses and Dissertations

Understanding how the functionality of marine microbial communities change over time and space, and which taxonomic groups dominate distinct metabolic pathways, are essential to understanding the ecology of these microbiomes and the factors contributing to their regulation of elemental cycles in the oceans. The primary goal of this dissertation was to investigate the community metabolic and taxonomic responses and the degradation potential of two compositionally distinct marine microbiomes within the shallow shelf ecosystem of the Chukchi Sea after rapid fluctuations in algal organic matter availability. Novel bioinformatics tools were collaboratively developed and used together with community proteomics (metaproteomics) to characterize …

Microhabitat Comparison Of Percina Roanoka (Roanoke Darter) And Percina Nevisense (Chainback Darter) In The Roanoke River, Dakota R. Spruill, Steven L. Powers

Virginia Journal of Science

Snorkel observations of Percina roanoka and P. nevisense in the Roanoke River during summer months were followed by measuring current velocity, water depth, and substrate diameter at points of occupation. A total of 89 observations of P. roanoka and 81 observations of P. nevisense were compared using two-sample T-tests. Percina roanoka inhabited faster, shallower water than P. nevisense with the former found in a mean flow of 0.318 m/s and depth of 31.53 cm and the latter in a mean flow of 0.17 m/s and depth of 55.6 cm. Mean diameter of substrate at points of occupation did not …

Detecting Change: Observations Of Temperature And Precipitation Across Virginia’S Climate Divisions, Jeremy S. Hoffman, Michael J. Allen, Christopher F. Labosier

Virginia Journal of Science

Modern global climate change is primarily attributable to human activities and the release of greenhouse gases into the atmosphere. Climate change impacts span a range of sectors, including agriculture, forestry, public health, and water resource management. The Commonwealth of Virginia has already and will continue to deal with many of these impacts, yet lacks concentrated effort to detect, document, and adapt to local climate changes. This study documents observed changes in temperature and precipitation across Virginia’s six climate divisions. Mean seasonal anomalies of minimum temperature, maximum temperature, and precipitation from 1986 to 2016 are examined relative to a long-term 1895-2000 …

The Women Of Explosive Ordnance Disposal: Cyborg, Techno-Bodies, Situated Knowledge, And Vibrant Materiality In Military Cultures, April Michelle Cobos

English Theses & Dissertations

Women’s service in the U.S. Explosive Ordnance Disposal (EOD) community began in the 1970s amidst policy changes that opened more active duty roles to women while maintaining restrictions on their access to combat. However, in the past two decades, the changing contexts of war brought the EOD community, and subsequently, these women to the forefront of combat preceding the 2016 policy repeal, positioning these women at a poignant, kairotic moment in history. The exigency of such a project in the field of rhetoric applies to more broadly analyzing the disparities between policy discourse and the lived experiences of individuals who …

Off Axis Compressive Response Of Ice-Templated Ceramics, Rahul Kumar Jujjavarapu

Mechanical & Aerospace Engineering Theses & Dissertations

The off-axis compressive behavior of ice-templated ceramic was analyzed using experimental results and micro-mechanical model simulation. Ice-templated ceramics is a versatile processing technique used to manufacture anisotropic ceramic foam by exploiting the anisotropic growth characteristics and lamellar morphology. The ice-templating process results in processing-structure-property relationships determined by the microstructure. The processed alumina samples which were later manufactured by water jet machine from the freeze casting were tested under quasi-static off-axis loading conditions and were used to determine the mechanical properties of the material. Digital image correlation (DIC) was used to measure the strain response of ice-templated ceramic under off-axis loading. …

Design And Manufacture Of An Inertial Cascade Impactor For Industrial Hygiene Purposes, Hector Joel Gortaire

Mechanical & Aerospace Engineering Theses & Dissertations

Inertial cascade impactors are devices commonly used for industrial hygiene and pharmaceutical studies. Their main purpose is to separate particulate matter suspended in aerosols according to their sizes, which can vary from over 10 µm to 0.5 µm. Their versatility and ease of operation make them suitable for on-site sampling; however, designing them requires a careful consideration of the different geometric parameters that characterize them.

In this thesis, a 5-stage inertial cascade impactor was designed, modelled, constructed, and tested. The main design parameter was the volumetric flow rate, 40 l/min, which was provided by a vacuum pump. By continuous iterations, …

The Impact Of Anterior Cruciate Ligament Reconstructive Surgery On Neuromotor Function, Cortney Noel Armitano

Rehabilitation Sciences Theses & Dissertations

The purpose of this dissertation was to examine the systemic neuromechanical implications in individuals who have had an ACL reconstruction (ACLR) compared to healthy controls. The specific aims addressed were to: 1) examine differences in inter-limb coordination during walking at different speeds, 2) examine differences in trunk, neck and head acceleration during gait, and 3) investigate whether the reaction time responses assessed during stepping are negatively affected by ACLR.

The findings of study 1 revealed that maximal coordination stability was achieved when walking at the person’s preferred gait speed. However, individuals with a previous ACLR exhibited reduced coordination stability between …
