Investigation Of Models To Predict The Remaining Useful Life Of Prestressed Concrete Cylinder Pipe, Ahmad Mahmoud Jibreen

Civil Engineering Dissertations - Archive

The water distribution system in the United States consists of 2.2 million miles of pipelines with water main breaks that the American Society of Civil Engineers (ASCE) 2021 Report Card estimated results in six billion gallons of drinking water lost daily. Detecting the state of pipeline deterioration should always be a top priority in the water pipeline industry This dissertation statistically evaluates data from more than 70,000 electromagnetic inspections that have been performed since the installation of these pipes in 1971. The scope of this dissertation is related to performance and degradation of prestressed concrete cylinder pipe (PCCP) which is …

Factors Affecting Health-Seeking Behaviour Among Men Who Have Sex With Men In Starehe Sub-County, Nairobi City County, Anthony Omariba

MSc in Advanced Practice Nursing

Men who have sex with other men (MSM) exist in Africa, as they do elsewhere. The continued proscription of MSM behavior leads to exclusion and discrimination. According to a global report, MSMs are responsible for most HIV transmission. MSMs in Kenya constantly fear being hurt because of their sexual orientation, and there is scant knowledge of their health-seeking behavior. There is a need to improve the health of this group to lower disease spread to achieve global HIV reduction. This study aims to explore MSM healthcare-seeking behavior, describe barriers to healthcare-seeking, and establish perceptions of the sexual risks associated with …

Ocean acidification (OA) has resulted in global-scale changes in ocean chemistry, which can disturb marine organisms and ecosystems. Despite its extensively populated coastline, many marine-dependent communities, and valuable economies, the Gulf of Mexico (GOM) remains a relatively understudied region with respect to acidification. In general, the warm waters of the GOM are better buffered from acidification compared to higher latitude seas, yet long-term acidification has been documented in several GOM regions. OA within the GOM is recognized as spatially variable, particularly within the coastal zone where numerous physical and biogeochemical processes contribute to carbonate chemistry dynamics. The historical progression of …

Simulation Of Low Energy Waves During Fair-Weather Summer Conditions In The Northern Gulf Of Mexico: Effect Of Whitecapping Dissipation And The Forcing Accuracy, Nazanin Chaichitehrani, Mohammad Nabi Allahdadi, Chunyan Li

Faculty Publications

Simulating WAves Nearshore (SWAN) on a structured grid over the Louisiana shelf in the northern Gulf of Mexico is used to evaluate the performance of three different classes of formulations for quantifying wind input and whitecapping dissipation. The formulations include Komen based on the mean spectral parameters, Westhuysen based on the saturation concept of the wave groups, and the most recent observation-based physics package ST6. The evaluation was implemented for two summer months (July and August 2015) to assess these formulations for a low wave energy period. The modeling area consists of the Louisiana inner shelf with the offshore open …

New Data On Court Curbing By State Legislatures, Meghan Leonard

Faculty Publications – Politics and Government

The examination of the interaction between the institutions in American state politics has long suffered from a dearth of data. This is the case despite the importance of understanding the separation of powers in the states and the specific effects on policy making and policy outcomes. In this article, I introduce a new, original dataset of court-curbing introductions by state legislators. The data include information on more than 1,200 state legislative bills that would restrict the power of the courts. In this article, I provide descriptive statistics for the data, employ the data to test hypotheses, and explain how this …

Constitutional Adjudication In The United States As A Means Of Advancing The Equal Stature Of Men And Women Under The Law, Ruth Bader Ginsburg

Hofstra Law Review

In this article, the author discusses dissenting opinion in which the Supreme Court held that, under the Constitution's equal protection principle, the Commonwealth of Virginia could not exclude from a public military college. It mentions commitment in the Declaration of Independence to equality and in the Declaration and Bill of Rights to individual liberty. It also mentions Civil War ended slavery, through the addition of the Equal Protection Clause to the Constitution.

An Ai-Based Framework For Studying Visual Diversity Of Urban Neighborhoods And Its Relationship With Socio-Demographic Variables, Md Amiruzzaman, Ye Zhao, Stefanie Amiruzzaman, Aryn C. Karpinski, Tsung Heng Wu

Computer Science Faculty Publications

This study presents a framework to study quantitatively geographical visual diversities of urban neighborhood from a large collection of street-view images using an Artificial Intelligence (AI)-based image segmentation technique. A variety of diversity indices are computed from the extracted visual semantics. They are utilized to discover the relationships between urban visual appearance and socio-demographic variables. This study also validates the reliability of the method with human evaluators. The methodology and results obtained from this study can potentially be used to study urban features, locate houses, establish services, and better operate municipalities.

Applied Studies Of Raptor Sensory Ecology Are Rare, Christopher J.W. Mcclure, Simon Potier, Jesse R. Barber

Biology Faculty Publications and Presentations

Light and noise often act as pollutants, but can also be used as tools for managing wildlife (e.g., sensory deterrents). Given that raptors are among the most threatened groups of birds, we expected there to be a moderate amount of applied research on their sensory ecology. We searched Web of Science and Google Scholar to quantify and classify the research that has been conducted on the applied sensory ecology of raptors. Of 32 studies assessing the effects of sensory pollution on raptors, we found that 10 studies examined effects of light pollution and 24 studies examined effects of noise pollution. …

Drone Imagery Protocols To Map Vegetation Are Transferable Between Dryland Sites Across An Elevational Gradient, Anna Roser, Josh Enterkine, Juan M. Requena-Mullor, Nancy F. Glenn, Alex R. Boehm, Marie-Anne De Graaff, Patrick E. Clark, Fred Pierson, T. Trevor Caughlin

Biology Faculty Publications and Presentations

The structure and composition of plant communities in drylands are highly variable across scales, from microsites to landscapes. Fine spatial resolution field surveys of dryland plants are essential to unravel the impact of climate change; however, traditional field data collection is challenging considering sampling efforts and costs. Unoccupied aerial systems (UAS) can alleviate this challenge by providing standardized measurements of plant community attributes with high resolution. However, given widespread heterogeneity in plant communities in drylands, and especially across environmental gradients, the transferability of UAS imagery protocols is unclear. Plant functional types (PFTs) are a classification scheme that aggregates the diversity …

Brain Waste Among Highly Skilled Immigrants In The United States, Kimberly Alva-Chavers Gardner

Master's Projects and Capstones

The issue of brain waste and underemployment among highly skilled immigrants is a key issue facing the United States today. This problem of equity has turned into an issue of economic stability in a country with a waning population whose workforce will soon depend on immigrant and international workers. Multiple agencies, including government programs and nonprofits, are attempting to address this issue from a language learning perspective. Using the theoretical framework of Cultural Capital and Community Cultural Wealth, this research project suggests that the key to reducing brain waste and underemployment among highly skilled immigrants is to take the focus …

Biomechanical And Sensory Feedback Regularize The Behavior Of Different Locomotor Central Pattern Generators, Kaiyu Deng, Hillel J. Chiel, Roger D. Quinn

Faculty Scholarship

This work presents an in-depth numerical investigation into a hypothesized two-layer central pattern generator (CPG) that controls mammalian walking and how different parameter choices might affect the stepping of a simulated neuromechanical model. Particular attention is paid to the functional role of features that have not received a great deal of attention in previous work: the weak cross-excitatory connectivity within the rhythm generator and the synapse strength between the two layers. Sensitivity evaluations of deafferented CPG models and the combined neuromechanical model are performed. Locomotion frequency is increased in two different ways for both models to investigate whether the model’s …
