Feature investigation using micro computed tomography within materials
(2018-05)
This work uses micro computed tomography, as a direct non-destructive tool, to investigate the internal 3D microstructure of different materials at multiple length scales to provide insights that are of interest to the ...
Evaluation of emissions reduction strategies for heavy duty diesel construction equipment
(2018-07)
Heavy-duty diesel (HDD) construction equipment expends a considerable amount of fuels and correspondingly emits a substantial amount of pollutants to the air. This dissertation assesses potential impacts of diesel exhaust ...
Evaluation of pavement skid resistance using computational intelligence
(2018-08)
Pavement micro-texture is affected by the aggregate characteristics contained within the surface. It is long desired to develop friction prediction models using pavement surface and aggregate textural properties. However, ...
Visualization and intelligent solutions for big pavement data
(2018-07)
Pavement visualization and crack detection are two important components supporting modern pavement condition survey. In this dissertation, two major goals are accomplished based on implementable algorithms. 1) The long-distance ...
Investigating resistivity testing as a method for quality control of concrete mixtures
(2018-05)
Concrete is a composite material. It is a mixture of cement, sand, rocks and water. It is the second largest consumable product in the world. Unfortunately, many of the concrete structures before completing the designed ...
