Microtopography-Dominated Discontinuous Overland Flow Modeling and Hydrologic Connectivity Analysis
(North Dakota State University, 2014)Surface microtopography affects a series of complex and dynamic hydrologic and environmental processes that are associated with both surface and subsurface systems, such as overland flow generation, infiltration, soil ... -
Modeling of Dynamic Hydrologic Connectivity: How Do Depressions Affect the Modeling of Hydrologic Processes?
(North Dakota State University, 2018)Traditional delineation and modeling methods do not consider the spatial arrangement and dynamic threshold control of surface depressions. Instead, full structural hydrologic connectivity, uniform well-connected drainage ... -
Multiscale Modeling of Conjugated Polymers Towards Predicting Their Multifunctional Behaviors
(North Dakota State University, 2022)Easy processability, tunable mechanical and optoelectronic properties, and the endless possibilities of molecular modifications enable conjugated polymers (CPs) to be used in a wide range of lightweight, low-cost, and ... -
Neural Networks and Sensitivity Analysis for Detection and Interpretation of Structural Damage
(North Dakota State University, 2021)Computer vision (CV)-based approaches have gained a lot of attention in recent years for objective identification of damages both at structural and material scales. In this dissertation, the metallurgical phases and the ... -
A New Macro-Scale Hydrologic Processes Simulator for Depression-Dominated Cold Climate Regions
(North Dakota State University, 2019)The primary objectives of this dissertation research are to (1) improve the understanding of macro-scale hydrologic processes in cold climate regions, (2) improve macro-scale representation and modeling of depression-dominated ... -
Optimizing Selection and Implementation Protocols of Lean Construction Tools and Techniques for Rapid Initial Successes
(North Dakota State University, 2021)Lean construction (LC) has been considered as one of the most promising project management philosophies to overcome low productivity and excessive waste issues impacting the construction industry. Despite strong philosophies ... -
Parametric Cost Estimating and Risk Analysis of Transportation Tunneling Projects
(North Dakota State University, 2016)Due to the increased scrutiny of construction costs for infrastructure projects by the public and legislators, it is becoming increasing important for project developers to prepare accurate conceptual cost estimates for ... -
Post-Fire Damage and Corrosion in Structural Steels: Characterization and Prevention
(North Dakota State University, 2021)Steel structures frequently experience extreme service conditions such as fire accidents, corrosion, etc., resulting in significant deterioration, reduced service life, and increased maintenance cost. Almost 0.5 million ... -
Safety Effectiveness and Safety-Based Volume Warrants of Right-Turn Lanes at Unsignalized Intersections and Driveways on Two-Lane Roadways
(North Dakota State University, 2012)Disagreements regarding to what degree right-turn lanes improve or worsen the safety of intersections and driveways provided the motivation and the need for this study. The objectives of this study were to: a) carry out ... -
Spatial Scale Dependence of Drought Characteristics and Impact of Drought on Agriculture and Groundwater
(North Dakota State University, 2016)Drought is a water related natural hazard. It is difficult to characterize drought because of its diffused nature and spatiotemporal variability. However, understanding the variability of drought characteristics such as ... -
A Stochastic Bayesian Update and Logistic Growth Mapping of Travel-Time Flow Relationship
(North Dakota State University, 2017)The travel-time flow relationship is not always increasing in nature, it is very difficult to predict precisely. Traditional method fails to replicate this unique conditions. Until millennium, although various researchers ... -
Systemic Analyses and Indicators for Assessing Risks to Drinking Water Resources from Hydraulic Fracturing Chemicals
(North Dakota State University, 2021)Hydraulic fracturing (HF) is a disruptive technology that has unlocked a vast amount of hydrocarbon resources, but presents risks to drinking water resources. Applying systemic risk assessment approaches to environmental ... -
Traffic Monitoring System Using In-Pavement Fiber Bragg Grating Sensors
(North Dakota State University, 2019)Recently, adding more lanes becomes less and less feasible, which is no longer an applicable solution for the traffic congestion problem due to the increment of vehicles. Using the existing infrastructure more efficiently ... -
Weak Organic Acid Modified Granular Activated Carbon and Ceria Nanomaterial Embedded Graphene Oxide for Drinking Water Fluoride Removal
(North Dakota State University, 2021)Excess fluoride (F−) in drinking water leads to detrimental health effects including dental and skeletal fluorosis. More than 260 million people worldwide are affected by excess fluoride (>1.5 mg/L) in their drinking water. ...
