Assessing Wrf Precipitation Forecasts Of Atmospheric Rivers In Northern California Using 4d-Var Data Assmiliation Of Cosmic-2 Gps Radio Occultation Profiles, Paul R. Zechiel

Master's Theses

Atmospheric Rivers (ARs) can provide much needed water to drought-ridden locations, however, can also lead to potential devastating flooding events. Thus, AR forecasts must be improved to keep the public safe. This case study used the Weather Research and Forecasting (WRF) model to compare the impact of including COSMIC-2 GPS Radio Occultation (RO) measurements using 4D-VAR data assimilation techniques. Each WRF simulation analyzed the vertical motion, pressure, mixing ratios with respect to ice, rain, and vapor, and precipitation fields. To provide observational precipitation data for model comparison, the Integrated Multisatellite Retrievals for Global Precipitation Measurement (IMERG) satellite and the Santa …

Development And Characterization Of An Underwater Acoustics Laboratory Via In Situ Impedance Boundary Measurements, Cameron Taylor Vongsawad

Theses and Dissertations

Modeling underwater acoustic propagation comes with a variety of challenges due to the need for proper characterization of the environmental conditions. These conditions include ever changing and complex water properties as well as boundary conditions. The BYU underwater acoustics open-air tank test-bed and measurement chain were developed to study underwater acoustic propagation within a controlled environment. It was also developed to provide ways to test and validate ocean models without the high cost associated with obtaining open ocean measurements. However, tank measurements require additional characterization of boundary conditions associated with the walls of the tank which would not be present …

Rad Managers: Strategic Coaching For Managers And Leaders, Audrey Mika Kinase Kolb

Industrial-Organizational Psychology Dissertations

Objective: Managerial coaching is a nascent area of research; as such there are few models supported by independent inquiry endorsing their effectiveness in impacting employee outcomes. The purpose of the current investigation was to present a concise, practical model of managerial coaching (RAD: relationships, accountability, development) that can be used for teaching and evaluating coaching behaviors. The model was hypothesized to predict ratings of coaching effectiveness (CE), perceptions of supervisor support (PSS), occupational self-efficacy (OSE), and work engagement (WE). Further, each factor of the model was tested in a series of secondary hypotheses to determine which factors were …

International Law Studies

In this article the revolution in fiber optic submarine cable communications is placed in context with the world’s growing dependence upon critical submarine cable infrastructure. Emphasis is placed on the development of international law designed to protect submarine cables and in particular those articles in the United Nations Law of the Sea Convention that foster and safeguard the freedom to lay and repair submarine cables. Special focus is applied to the status of international submarine telecommunication cables in cases of intentional actions that damage or destroy them and the State practice and customary international law that generally classifies submarine cables …

Finding Neverland? Artificial Intelligence And The Jurisprudence Of Legal Certainty, Omar Zaky

Theses and Dissertations

The development of artificial intelligence (AI) models that are capable of predicting the decisions of prominent courts – most notably the European Court of Human Rights and United States Supreme Court – provides us with an opportunity to revisit important jurisprudential debates regarding the quest for legal certainty. Through providing clear distinctions within formalistic jurisprudence, and its, subsequent, realist critique; this thesis seeks to analyze legal decision-making and its relationship with artificial intelligence. I argue that, AI’s deterministic nature and its support for the law being an “entirely self-contained process” does lend some credence to certain jurisprudential arguments. However, this …

Acute Pediatric Chagas Disease In Antioquia, Colombia: A Geographic Location Of Suspected Oral Transmission, Lídia Gual-Gonzalez, Catalina Aango-Ferreira, Laura Camila Lopera-Restrepo, Omar Cantillo-Barraza, Daniela Velásquez Marín, Natalia Restrepo Bustamante, Omar Triana-Chavez, Melissa Nolan Ph.D., Mph

Faculty Publications

Chagas disease, Trypanosoma cruzi infection, is an insidious cause of heart failure in Latin America. Early diagnosis and treatment are critical to prevent irreversible myocardial damage that progressively accumulates over decades. Several structural barriers account for the less than 1% of cases in Colombia being treated, including poor physician knowledge, especially considering that some regions are considered non-endemic. The two cases reported here represent an emerging epidemiologic scenario associated with pediatric Chagas disease. Both cases are suspected oral transmitted parasitic infection in a geographic region of Colombia (Andean region of Antioquia) where no previous oral transmission of Chagas disease had …

We conducted a one-way MANCOVA on Year 3 data, with gambling industry tenure as the covariate, and a …

Bayesian, Frequentist, And Information Geometry Approaches To Parametric Uncertainty Quantification Of Classical Empirical Interatomic Potentials, Yonatan Kurniawan

Theses and Dissertations

Uncertainty quantification (UQ) is an increasingly important part of materials modeling. In this paper, we consider the problem of quantifying parametric uncertainty in classical empirical interatomic potentials (IPs). Previous work based on local sensitivity analysis using the Fisher Information has shown that IPs are sloppy, i.e., are insensitive to coordinated changes of many parameter combinations. We confirm these results and further explore the non-local statistics in the context of sloppy model analysis using both Bayesian (MCMC) and Frequentist (profile likelihood) methods. We interface these tools with the Knowledgebase of Interatomic Models (OpenKIM) and study three models based on the Lennard-Jones, …

To Lift Or Not To Lift: An Institutional Ethnography Of Patient Handling Practices, Hans-Peter De Ruiter

Dissertations

The handling (lifting, mobilizing, moving etc) of patients is an integral part of the carework in health-care institutions. For obvious reasons, this puts healthcare providers at risk for musculoskeletal injuries (MSIs); furthermore the risk of such injuries has been considered an inherent risk of care work. In the last decade a concerted effort has been made to decrease (with the goal of eliminating) caregiver injuries by implementing safe patient handling programs (SPHP). These programs are presented as evidence-based algorithms that require the use of mechanical lifting devices. Institutions implement SPHPs as policies and procedural guidelines to which caregivers must conform. …

Recurrent Stroke Prediction Using Machine Learning Algorithms With Clinical Public Datasets: An Empirical Performance Evaluation, Fadratul Hafinaz Hassan, Mohd Adib Omar

Baghdad Science Journal

Recurrent strokes can be devastating, often resulting in severe disability or death. However, nearly 90% of the causes of recurrent stroke are modifiable, which means recurrent strokes can be averted by controlling risk factors, which are mainly behavioral and metabolic in nature. Thus, it shows that from the previous works that recurrent stroke prediction model could help in minimizing the possibility of getting recurrent stroke. Previous works have shown promising results in predicting first-time stroke cases with machine learning approaches. However, there are limited works on recurrent stroke prediction using machine learning methods. Hence, this work is proposed to perform …

Secret Sharing And Its Variants, Matroids,Combinatorics., Shion Samadder Chaudhury Dr.

Doctoral Theses

The main focus of this thesis is secret sharing. Secret Sharing is a very basic and fundamental cryptographic primitive. It is a method to share a secret by a dealer among different parties in such a way that only certain predetermined subsets of parties can together reconstruct the secret while some of the remaining subsets of parties can have no information about the secret. Secret sharing was introduced independently by Shamir [139] and Blakely [20]. What they introduced is called a threshold secret sharing scheme. In such a secret sharing scheme the subsets of parties that can reconstruct a secret …

On The Synthesis Of Optimal Control Laws, Meir Pachter, Isaac E. Weintraub

Faculty Publications

In this paper we advocate for Isaacs' method for the solution of differential games to be applied to the solution of optimal control problems. To make the argument, the vehicle employed is Pontryagin's canonical optimal control example, which entails a double integrator plant. However, rather than controlling the state to the origin, we correctly require the end state to reach a terminal set that contains the origin in its interior. Indeed, in practice, it is required to control to a prescribed tolerance rather than reach a desired end state; achieving tight tolerances is expensive, and from a theoretical point of …

A Variable Unit Hydrograph Incorporating Nonlinearity In Rainfall-Runoff Response Due To Antecedent Watershed Conditions, Aashis Sapkota

Electronic Theses and Dissertations Archive

Runoff generation in a watershed is a highly complex process whose estimation is vital in performing engineering tasks such as flooding risk assessments and design of hydraulic structures. Because natural rainfall-runoff processes are complex and inherently nonlinear, they are difficult to quantify or parametrize. In engineering hydrology, this issue has been mostly circumvented by using highly simplified, lumped approaches. Typically, losses are abstracted from a total precipitation hyetograph (representing either an actual or a design storm, depending on the application) to obtain the effective rainfall component, that is understood to result in the corresponding flood event. Then, this effective precipitation …

ABSTRACT

Libraries use orientation as one of the marketing tools to introduce their clientele and potential patrons to the services and resources at their disposal. However, the means to measure the impact of the orientation programme is not clear as students still find it difficult to use the library effectively; based on this, the study investigated the effectiveness of present-day library orientation methods and their impact on students of the Law Faculty of KNUST library usage. Using a quantitative case study design, the study involved a randomly selected sample of 200 undergraduates out of a population of 721 students from …

Association Between Meal Dietary Inflammatory Potential And Postprandial Sleepiness, Samantha Beth Kalb

Master's Theses

The amount and composition of food that is consumed are known to contribute toinflammation and may affect how we feel in the following hours. The aim of this research was to determine if the inflammatory potential of a single meal is associated with level of postprandial sleepiness. Participants (n = 70) recorded intake of one of their meals, then reported their degree of postprandial sleepiness (Stanford Sleepiness Scale), average activity level, average hours of nightly sleep, and daytime sleepiness (Epworth Sleepiness Scale). The Dietary Inflammatory Index (DII) of the meal was estimated by adjusting DII parameters by 26%, reflecting the …

Computational Analysis Of Changing Wavelength On Bottom Rib And Side Rib Wavy Microchannel Heat Sinks, Ty C. Kieger

Master's Theses

As the power capacity of microelectronics continues to increase while their volume and size decrease, many different on-chip methods including microchannel heat sinks (MCHS) are being explored to cool down the temperature of these electronics. Wavy MCHS have been proven to yield better heat transfer performance compared to straight MCHS, while only producing a slightly larger pressure drop. This study investigates the heat transfer performance of MCHS following a vertical wavy design and a horizontal wavy design that have the same cross-sectional area. The simulations show that vortices are produced along the channel in the peaks and troughs of the …

Examining The Effects Of Power Posing On Stress Reactivity And Performance, Mitzi D. Ochoa

Master's Theses

Power posing is a concept that has garnered widespread attention due to claims thatan expansive powerful posture can improve self-perceptions of power, trigger changes in hormone levels, and improve behavioral outcomes including enhanced performance in social evaluative situations. Recently, these claims have been challenged by studies that failed to replicate the power boosting effects of expansive poses. This study aimed to address inconsistencies in the power posing literature and replicate original findings while controlling for potential effects of experimenter bias and touch. It was predicted that a high-power pose would reduce cortisol, increase perceptions of power, and improve performance. To …

Two-Level Data Augmentation With Transfer Learning For Classification Of Medical Images With Limited Data, Nihil Pudota

Master's Theses

Machine learning used in the medical industry can potentially detect cancer in humancells at an early stage. However, training the machine learning models, especially deep learning models require thousands to millions of samples in order to reach an acceptable accuracy level. It is well-know that obtaining medical data is tedious hence in most cases, medical datasets have limited number of data samples. One solution for this problem is utilizing transfer learning such as pretrained networks on another dataset. Another solution is to increase the number of training data points with data augmentation. Common data augmentation methods for images include not …

Faster Depth Estimation For Situational Awareness On Urban Streets, Sanjana Srinivas

Master's Theses

Depth estimation algorithms are useful components of computer vision systems toassess video streams on urban streets. They can provide important information about the street space and improve situational awareness for humans. Deep learning algorithms for depth estimation are slow in providing on-time street evaluation for the users. To provide situational awareness to humans, the inference time needs to be small, so that results are fresh and meaningful. This paper explores approaches like switching to efficient convolutional neural network, quantization and pruning to improve inference time with a little compromise on the performance. We explore the impact of each of these …

Library Philosophy and Practice (e-journal)

Librarian behavior has brought a positive change in the students' lives. Librarian love encourages the students' stay in the public libraries of high schools. A decade ago, the world paid a high price for corporal punishment; in turn, the students faced a high level of stress and anxiety. However, UNESCO has launched a slogan, 'No punishment but love' all over the world. Therefore, this study measures the impact of librarian love on students' personality development, e.g., discipline, emotional behavior, and perceived respect. Additionally, this study sees whether the high school librarians perceive a positive impact on their discipline, emotional behavior, …

Characterization And Interpretation Of Feldspathic Chromite Assemblages (Fcas) In Four Ordinary Chondrites: An Electron Backscatter Diffraction (Ebsd) Study, Kimberly Louisa Maccini

Dissertations and Theses

Feldspathic Chromite Assemblages (FCAs) are chemically distinctive assemblages rich in Na, Al, and Cr that are found in a variety of chondrites. They consist of concentrations of chromite associated mainly with feldspathic material, either feldspar or the glassy material known as maskelynite. Professor Alan Rubin (2003) has proposed that some FCAs formed by shock melting, but the origin of different types of feldspathic chromite assemblages are unclear and have not been studied with more modern techniques such as Electron Backscatter Electron Diffraction (EBSD).

Here EBSD was used to study FCAs in four metamorphosed ordinary chondrites of different shock stages, including …
