A User-Friendly Wrapper for DSIDES (Decision Support in the Design of Engineering Systems)
(2023-11-15)When dealing with complex systems, we need to consider that these systems have behaviors that are hard to predict or control, and uncertainties are always present since computational models are abstracts of reality. It is ... -
Systems approach to the remote operation of a hydraulic fracturing missile
(2023-12-15)Hydraulic fracturing missiles are a critical piece of equipment in the hydraulic fracturing process. If there is a failure, people have to enter a high-risk area to shut off pressurized lines. Entering the high-pressure ... -
Water use conflicts in the Lower Pecos, Permian Basin: A spatio-temporal analysis of unconventional oil and gas development and agriculture under drought conditions
(2023-12-15)Unconventional oil and gas (UOG) production is increasing rapidly within the U.S., especially the practice of hydraulic fracturing (HF). HF requires large quantities of water, which raises concerns about water scarcity, ... -
Integrated Hydrologic Validation of Satellite Precipitation over the United States
(2023-12-15)Increasing precipitation extremes across the globe will naturally lead to not only increased flooding but an increase in the occurrences of flash floods, with assessment and prediction of these events becoming more critical ... -
Integrated protonic ceramic electrochemical cell for sustainable energy economy using water-energy nexus framework
(2023-12-15)Reliance on fossil fuels will continue for the next decades even though there are global pushes away from it to mitigate the overarching climate challenge, most especially by its highest consumers and availability. While ... -
Effects of Hydraulic Design and Retention Time on Removal of Constituents of Emerging Concern from Secondarily Treated Wastewater Effluent in Treatment Wetland Mesocosms
(2023-12-15)Treatment wetlands (TWs) are an ecologically engineered, natural infrastructure approach designed specifically for water quality improvement via natural biogeochemical, physiochemical, and microbiological processes. The ... -
Application of deep learning to optimize computer-aided-detection and diagnosis of medical images
(2023-12-15)The field of medical imaging informatics has experienced significant advancements with the integration of artificial intelligence (AI), especially in tasks like detecting abnormalities in retinal fundus images. This ... -
Optimization of red brick dust-based geopolymers for use in sustainable construction
(2023-12-15)With the rising carbon dioxide levels affecting climate change, sustainable and eco-friendly alternatives to ordinary portland cement (OPC) are being investigated. To reduce the overall environmental impact, industrial ... -
Enhancing Performance and Reducing Emissions in Natural Gas Aspirated Engines through Machine Learning Algorithm
(2023-12-15)In an era where the global energy landscape is increasingly defined by the dual imperatives of efficiency and sustainability, the natural gas sector stands at a crucial juncture. The engines powering this sector, especially ... -
Examining the Predictability of Tornadic and Nontornadic Non-Supercellular MCS Storms using GridRad-Severe Radar Data and Machine Learning Techniques
(2023-12-15)Many studies have aimed to identify novel storm characteristics that are indicative of current or future severe weather potential using a combination of ground-based radar observations and severe reports. However, this is ... -
Kidney OCT 3D images classification using machine learning
(2023-12-15)The goal of this research is to make a classification program for 3D images by using a CNN model. The images to classify are kidney images that have 3 different classes: Pelvis, Medulla and Cortex. To do so, a data ... -
Machine learning for classifying biological radar echoes with S-band polarimetric radar
(2023-12-15)The S-band WSR-88D weather radar is sensitive enough to observe biological scatterers like birds and insects. However, their non-spherical shapes and frequent collocation in the radar resolution volume create challenges ... -
Bridging Micro- and Macro- Evolution In Tropical Fishes
(2023-12-15)In marine environments, barriers to dispersal can be challenging to identify because they are often cryptic. Unlike terrestrial environments, where a mountain chain that is visible can physically separate two populations ... -
Object detection in dual-band infrared
(2023-12-15)Dual-Band Infrared (DBIR) offers the advantage of combining Mid-Wave Infrared (MWIR) and Long-Wave Infrared (LWIR) within a single field-of-view (FoV). This provides additional information for each spectral band. DBIR ... -
Feasibility of Blast Furnace Slag for Stabilizing Sulfate-Bearing Soil
(2023-12-15)Calcium-based stabilizers are frequently used by The Oklahoma Department of Transportation (ODOT) to enhance the strength and reduce the swelling potential of fine-grained soils. However, these stabilizers can lead to ... -
Study On The Use Of Facemask Fibers For Soil Reinforcement
(2023-12-15)This study investigated the potential application of facemask materials as a sustainable solution for soil reinforcement, with a focus on assessing the influence of facemask fiber attributes on the geotechnical properties ...
