Iron Waste Based Point-of-Use Device to Treat Pesticides in Water
(North Dakota State University, 2019)
Organochlorine pesticide (OCP) contamination in groundwater is a problem worldwide, more severely in rural areas that normally cannot afford centralized water treatment systems. Iron nanoparticles have shown their ability ...
Carboxymethyl Cellulose Surface Treatment Method to Disperse Carbon Nanotubes in Smart Cementitious Materials
(North Dakota State University, 2019)
An innovative surface treatment method was proposed using carboxymethyl cellulose (CMC) to surface-treat carbon nanotubes (CNTs) for a consistent dispersion in cementitious materials to achieve high force detection ...
Exploring Chemically Treated Fiber Reinforced Pervious Concrete Through Image Based Micromechanical Modeling
(North Dakota State University, 2019)
Pervious concrete has been widely used in parking lots and airport fields. However, past experience has shown durability and strength of the pervious concrete remains a challenge for adopting them in wider applications, ...
Seismic Energy Dissipation, Self-Centering, and Settlement of Rocking Foundations: Analysis of Experimental Data with Comparisons to Numerical Modeling
(North Dakota State University, 2019)
The major objective of this study is to correlate the rocking foundation performance parameters with their capacity parameters and earthquake demand parameters using the results obtained from 142 centrifuge and shaking ...
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 ...
Drive-By Bridge Damage Identification Through Virtual Simulations
(North Dakota State University, 2019)
With massive infrastructures built in US, timely condition assessment of these infrastructures becomes critical to daily traffic and economics. Due to high cost, long time consumption of direct condition assessment methods, ...
Comparitive Analysis of Turbidity and Organics Removal in Biological Activated Carbon and Anthracite-Sand Filters in the Moorhead Water Treatment Plant
(North Dakota State University, 2019)
The source water for the Moorhead Water Treatment Plant (MWTP) exhibits high concentrations of total organic carbon (TOC) throughout the year and seasonal taste and odor (T&O) events. To prevent biological regrowth in the ...
ADYTrack: A Model for Structural Analysis of Railroad Trackbed Using Random Finite Element Method
(North Dakota State University, 2019)
Railroads are playing pivotal role to the economic growth of United States and trackbeds ensure their safe and smooth operations. However, reliable trackbed performance prediction has always been challenging due to many ...
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 ...
Pore Structure and Pore Solution in Alkali Activated Fly Ash Geopolymer Concrete and Its Effect on ASR of Aggregates with Wide Silicate Contents
(North Dakota State University, 2019)
Alkali silica reaction (ASR) is detrimental to concrete. It is a time-dependent phenomenon, which can lead to strength loss, cracking, volume expansion, and premature failure of concrete structures. In essence, it is a ...
