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 ...
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, ...
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 ...
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 ...
