Machine Learning-Enabled Regional Multi-Hazards Risk Assessment Considering Social Vulnerability, Tianjie Zhang, Donglei Wang, Yang Lu

Civil Engineering Faculty Publications and Presentations

The regional multi-hazards risk assessment poses difficulties due to data access challenges, and the potential interactions between multi-hazards and social vulnerability. For better natural hazards risk perception and preparedness, it is important to study the nature-hazards risk distribution in different areas, specifically a major priority in the areas of high hazards level and social vulnerability. We propose a multi-hazards risk assessment method which considers social vulnerability into the analyzing and utilize machine learning-enabled models to solve this issue. The proposed methodology integrates three aspects as follows: (1) characterization and mapping of multi-hazards (Flooding, Wildfires, and Seismic) using five machine learning …

Interaction Of Natural Convection And Real Gas Radiation Over A Vertical Flat Plate, Nathan Hale

Theses and Dissertations

This study explores natural convection heat transfer and fluid flow from a vertical plate in a radiating gas accounting for real gas spectral behavior. Finite volume techniques are used to solve the coupled nonlinear partial differential equations for mass, momentum, and energy conservation, while radiation transfer is modeled using the Discrete Ordinates finite volume finite angle method. Real gas spectral behavior is accounted for using the Rank Correlated Spectral Line Weighted-sum-of-gray-gases method. It is found that gas temperature and velocity are higher in the boundary layer, thickening the thermal and hydrodynamic boundary layers compared to the limiting case of pure …

Modeling Of Heat And Mass Transfer In Flat Heat Pipes, Salar Saadatian

LSU Doctoral Dissertations

Phase-change phenomenon is ubiquitous in nature and widely utilized in thermal management of computer chips. Flat heat pipes have been extensively used in thermal management of microelectronic devices. However, existing research mainly concentrates on developing numerical models and lacks a systematic analytical approach to elucidate the working mechanism of flat heat pipes. We consider a horizontal flat heat pipe with an idealized porous wick. The pores in the wick are straight circular capillaries running along and across the wick and are filled with a liquid. The rest of the pipe is filled with its vapor. The mass evaporative rate at …

Cross-Environment Collective Cell Invasion After Mechanical And Hypoxic Priming, Jose Alejandro Almeida

McKelvey School of Engineering Graduate Student Theses & Dissertations

In breast cancer, tumor cells collectively move through microenvironments of varying stiffness and fiber structures. Around primary breast tumors, there are gradients of matrix stiffness that mammary epithelial cells (MECs) must navigate for tumor invasion. In addition, the collagen density of the breast tissue becomes more crosslinked and fibrous. Previous studies of breast tumor invasion capture the effect of either soft or stiff environments, not how cells coming from stiff environments behave in softer 3D collagen matrices. Across stiff and soft regions, we have previously shown a mechanical memory-dependent collective migration of epithelial cells on 2D surfaces. In this work, …

The Influence Of Facades On Outdoor Comfort And Behavior In Urban Spaces, Mingliang Li

Graduate School of Architecture & Urban Design Theses & Dissertations

Global warming and rapid urbanization have intensified the urban heat island (UHI) effect, and its effect on human comfort in urban spaces has attracted widespread attention. The UHI effect increases the risk of heat-related mortality and building energy consumption and reduces outdoor human thermal comfort. A comfortable outdoor space supports sustainable urbanism by making the outdoor environment more comfortable and usable, thereby helping reduce the time spent indoors and the energy consumption of buildings.

There are thermal, visual, and acoustic features that influence outdoor comfort in terms of human physical, psychological, and social behaviors. Building façades, a common component of …

A Novel Approach To Detect Modified Cytosines In A Nanopore Sequencer, Benjamin Davidorf

McKelvey School of Engineering Graduate Student Theses & Dissertations

Epigenetic changes, such as DNA methylation, have been seen in various types of cancers, diseases, and neurological disorders. A common form of methylation occurs when a methyl group is added to the C-5 position of a cytosine, which is called 5-methyl-cyosine (5- mC). Hydroxymethylated is a type of methylation where 5mC is oxidized to 5-hydroxy-methyl- cytosine (5hmC), which has been linked to normal brain development. Current methods to sequence DNA methylation patterns (5-mC and 5-hmC) at a genome-wide level have several limitations, so there remains a need for a method to efficiently map DNA methylation. The state- of-the-art method for …

A Review Of Recent Gene Expression-Based And Dna Methylation-Based Mathematical Cell Type Deconvolution Methods, Chenxiao Tian

Arts & Sciences Graduate Student Theses and Dissertations

In recent years, many cell type deconvolution methods based on DNA methylation data and gene expression data have been developed. Both of these two methods have its special advantages and disadvantages, e.g., DNA methylation-based methods’ data source is usually more stable than gene expression and DNA methylation is easier to measure in FFPE tissues or formalin-fixed paraffin-embedded, while some gene-expression data like scRNA-seq data usually has high cost and complexity. On the other hand, gene expression-based deconvolution methods currently have many more available methods than DNA methylation-based deconvolution methods, which leads to DNA methylation-based methods in many cases can learn …

Pyruvate Anaplerosis Is A Targetable Vulnerability In Persistent Leukaemic Stem Cells, Kevin M Rattigan, Zuzana Brabcova, Daniele Sarnello, Martha M Zarou, Kiron Roy, Ryan Kwan, Lucie De Beauchamp, Amy Dawson, Angela Ianniciello, Ahmed Khalaf, Eric R Kalkman, Mary T Scott, Karen Dunn, David Sumpton, Alison M Michie, Mhairi Copland, Saverio Tardito, Eyal Gottlieb, G Vignir Helgason

Faculty, Staff and Student Publications

Deregulated oxidative metabolism is a hallmark of leukaemia. While tyrosine kinase inhibitors (TKIs) such as imatinib have increased survival of chronic myeloid leukaemia (CML) patients, they fail to eradicate disease-initiating leukemic stem cells (LSCs). Whether TKI-treated CML LSCs remain metabolically deregulated is unknown. Using clinically and physiologically relevant assays, we generate multi-omics datasets that offer unique insight into metabolic adaptation and nutrient fate in patient-derived CML LSCs. We demonstrate that LSCs have increased pyruvate anaplerosis, mediated by increased mitochondrial pyruvate carrier 1/2 (MPC1/2) levels and pyruvate carboxylase (PC) activity, in comparison to normal counterparts. While imatinib reverses BCR::ABL1-mediated LSC metabolic …

A random forest algorithm was used as the supervised Machine Learning (ML) classifier for training and binary classification using acceleration, acoustics, temperature, and spindle speed during the orthogonal tube turning process as input features. The ML classifier was used to predict the condition of the tool after the cutting process, which was determined in a binary class form indicating if the cutting tool was available or failed. After the training process, the Shapley criterion was used to explain the predictions …

A Hybrid Many-Objective Optimization Algorithm For Job Scheduling In Cloud Computing Based On Merge-And-Split Theory, Mustafa Ibrahim Khaleel, Mejdl Safran, Sultan Alfarhood, Michelle Zhu

School of Computing Faculty Scholarship and Creative Works

Scheduling jobs within a cloud environment is a critical area of research that necessitates meticulous analysis. It entails the challenge of optimally assigning jobs to various cloud servers, each with different capabilities, and is classified as a non-deterministic polynomial (NP) problem. Many conventional methods have been suggested to tackle this difficulty, but they often struggle to find nearly perfect solutions within a reasonable timeframe. As a result, researchers have turned to evolutionary algorithms to tackle this problem. However, relying on a single metaheuristic approach can be problematic as it may become trapped in local optima, resulting in slow convergence. Therefore, …

Effects Of Annual Weather Variation On Peak Herbaceous Yield Date In Sagebrush Steppe, Jonathan Bates, Dustin Johnson, Kirk W. Davies, Tony Svejcar, Stuart Hardegree

Western North American Naturalist

Interannual climate variability impacts forage yield in semiarid rangelands, but it also affects the timing of peak yields. Knowledge of peak standing crop or yield dates would be useful when planning fieldwork for various research or management activities and for developing more accurate models linking herbage production to climatic variables. In this study, herbaceous yield was measured every 2 weeks (April–August) over an 8-year period in a Wyoming big sagebrush (Artemisia tridentata ssp. wyomingensis) community in southeastern Oregon. Date of peak yield (Julian day) was calculated for morphological groups (tall perennial bunchgrasses, perennial forbs, annual forbs), Sandberg bluegrass …

“Connecting Better And Wider”: A Constructivist Grounded Theory And Situational Analysis Exploration Of Community Resilience In The Anthropocene Among The Transition Network, Deanne M. Boisvert, Caroline Suransky

The Qualitative Report

For decades qualitative researchers have used grounded theory methodologies in their investigations. Although the grounded theory literature is extensive, less well documented are qualitative studies which incorporate complementary grounded theory approaches into their designs; or studies that validate the use of grounded theory strategies for applied research projects. This paper seeks to add to both margins of the grounded theory literature. First, it provides a detailed methodological account of how constructivist grounded theory and grounded theory situational analysis were used in a Ph.D. study exploring how ecologically concerned networks understand community resilience and respond to current and anticipated challenges of …

Mitigation Of Ground Control Issues Using Artificial Intelligence Techniques, Temitope Adebanjo

Engineering

Ground hazards are a major safety concern in underground mines, causing deaths, injuries, and lost work time to miners. Although ground hazards such as roof fall accidents have steadily and significantly declined over the last decade, the safety hazards associated with ground hazards still account for a significant portion of the total number of accidents in the underground mining industry. One of the main reasons behind ground hazards in underground mines is abrupt changes in geological conditions that may decrease the competence of the rocks surrounding an excavation, resulting in ground failure. The changes in geological can be detected in …

Improving The Efficiency Of A Flooded-Bed Dust Scrubber Using A Modified Demister, Darshil Asawa

Engineering

Dust generation is a significant issue in the U.S. mining industry, particularly the underground coal mining industry. It causes health and safety issues for the miners working underground. Prolonged exposure to high concentrations of respirable dust (dust of aerodynamic diameter < 10 μm) causes various diseases, including pneumoconiosis, also known as Black Lung, and silicosis. These diseases lead to an airflow blockage in the lungs, causing lung failure or death. Several techniques have been used to capture respirable dust particles, and a flooded-bed scrubber integrated into a continuous miner is one of them. This research focuses on increasing the efficiency of a flooded-bed scrubber by modifying the geometry of one of its components, known as a demister. A demister consists of a series of sinusoidal plates that separate water droplets from air and contribute to the capture efficiency and pressure drop across the scrubber. The geometry of the demister was modified by adding aerodynamic devices, called Vortex Generators (VG), on its plates. Several computational fluid dynamics (CFD) models of a modified demister were created, and CFD simulations were performed. An analysis of results indicated an improved water droplet capture efficiency for the modified demister. The study also discovered a potential to reduce the size of the demister which will reduce the pressure drop and eventually the energy consumption of the scrubber.

Geophysical Investigation Of Permafrost Conditions In A Thermokarst-Prone Area In Fairbanks, Alaska, Abdallah Basiru

Engineering

Permafrost degradation is a significant environmental concern for cold regions, posing risks to communities and infrastructure. The warming of near-surface permafrost leads to diverse topographic variations in the Arctic and sub-Arctic communities. The varying rates of thawing permafrost, influenced by ground ice content, give rise to geologic hazards like thermokarst, which causes ground subsidence. This gradual or sudden subsidence endangers existing infrastructure and economic activities in cold regions. A subsurface 2D Electrical Resistivity Tomography survey was conducted in the West Ridge area of the University of Alaska Fairbanks upper campus to advance our understanding of frozen ground conditions. The objective …

Development Of Sulfidogenic Bioremediation Technology For The Treatment Of Acid Mine Drainage In Alaska, Qifan Yang

Engineering

When it comes to the treatment of acid mine drainage (AMD), sulfate-reducing bioreactors are more sustainable and inexpensive compared to traditional alkaline treatment methods. As a passive system, sulfate-reducing bioreactors require not only less energy, but also less labor for operation. Sulfate reducing microbial community present in the bioreactor utilizes ����42− as electron acceptor and supplemented organic matter, such as glycerol, as terminal electron donor, and generates alkalinity and sulfides. This process not only neutralizes the acidity, but also removes soluble sulfate. The sulfides can further react with dissolved metal ions in the wastewater and produce precipitates. In this research, …

High Voltage Power Supply For A Small Plasma Spectrometer, Quetzal Luebke-Laroque

Engineering

This thesis describes the design, manufacturing, and testing of a high voltage power supply for an electron spectrometer to be used on a small spacecraft. The challenge was reducing complexity, size, and power consumption enough to be useful for a CubeSat or a sounding rocket sub-payload. The power supply has two purposes: i) it produces DC at roughly 2000 V for a microchannel plate detector and ii) it produces exponential voltage sweeps from about +4000 V to below 5 V for an electrostatic analyzer. This power supply uses solid state relays for a charge pump and for producing voltage sweeps …

A Framework For Creating Virtual Reality Models For More Effective Coastal Flood Risk Communication, Tina Korani, Alexandrea Martinez

CSU Journal of Sustainability and Climate Change

Coastal cities are exposed to increasing risks of flooding from sea-level rise. Climate change is expected to double the frequency of coastal flooding within the next decade, and some areas could experience floods of a magnitude 100 times higher than currently (Vitousek et al., 2017). People living in at-risk areas often ignore the impact of climate change on flood intensity and frequency. Immersive visual storytelling techniques proved promising and powerful tools to engage with and raise awareness of flood hazards. Here, we are introducing a framework to use Virtual Reality (VR) to reach better people living in coastal cities and …
