In Situ Groundwater Remediation using Enricher Reactor-Permeable Reactive Biobarrier
(North Dakota State University, 2012)
Permeable reactive biobarrier (PRBB) is a flow-through zone where microorganisms degrade contaminants in groundwater. Discontinuous presence of contaminants in groundwater causes performance loss of a PRBB in removing the ...
An Integrated System for Road Condition and Weigh-in-Motion Measurements using In-Pavement Strain Sensors
(North Dakota State University, 2016)
The United States has the world’s largest road network with over 4.1 million miles of roads supporting more than 260 million of registered automobiles including around 11 million of heavy trucks. Such a large road network ...
Corrosion Risk Assessment System For Coated Pipeline System
(North Dakota State University, 2018)
Steel is widely used as building material for large-scale structures, such as oil and gas pipelines, due to its high strength-to-weight ratio. However, corrosion attack has been long recognized as one of the major reasons ...
An Anisotropic Damage Mechanics Model for Concrete with Applications for Fatigue Loading and Freeze-Thaw Effects
(North Dakota State University, 2013)
It is well known that the formation and propagation of microcracks within concrete is anisotropic in nature, and has a degrading effect on its mechanical performance. In this thesis an anisotropic damage mechanics model ...
Energy-Saving Non-Metallic Connectors for Precast Sandwich Wall Systems in Cold Regions
(North Dakota State University, 2014)
Conserving energy in large structural buildings has become very important in today's economy. A number of buildings today are constructed with sandwich wall panels. Steel connections are most commonly used in these panels. ...
In-Pavement Fiber Bragg Grating Sensors for Weight-In-Motion Measurements
(North Dakota State University, 2016)
Estimation a traffic over the design period is one of the critical factors in pavement design. Weight-in-motion (WIM) sensors have become popular for weight measurements. A three-dimension glass fiber-reinforced polymer ...
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, ...
High-Throughput Methods for Characterizing the Mechanical Properties of Coatings
(North Dakota State University, 2012)
The characterization of mechanical properties in a combinatorial and high-throughput workflow has been a bottleneck that reduced the speed of the materials development process. High-throughput characterization of the ...
Silicon-Based Hybrid Organic-Inorganic Polymers and Coatings
(North Dakota State University, 2012)
Interest in producing hybrid organic-inorganic (HOI) materials has increased rapidly due to the unique combination of properties from the organic and inorganic components. The goal of the research described is to develop ...
Multiscale Modeling of Electromagnetic Radiation Transport
(North Dakota State University, 2013)
The transport of electromagnetic radiation is a critical factor in determining many of the advanced features of novel materials, composites, and coatings systems. The radiation interaction with a material's surface, as ...
