Development of precast, prestressed concrete pavement technology
(2013-12)
Precast prestressed concrete pavement (PPCP) can provide many advantages over other pavement alternatives whether asphalt or concrete. The possible advantages are thinner pavement, faster construction, increased durability, ...
Characterization of pollutant emissions and fuel use for CNG transit buses
(2015-05)
Transit agencies have historically relied on diesel buses to move their passengers; however, many agencies have adopted alternative fuels such as compressed natural gas (CNG). New knowledge is needed to accurately assess ...
Practical Numerical Analysis of a Three-Dimensional Trench Slurry Wall During Construction Using FLAC^3D
(2019-05-01)
A soil-bentonite cutoff wall is constructed by excavating a trench with a backfill mix of soil, bentonite, and water. The trench will be a vertical barrier to support the ground movement during construction and permanent ...

Scope and Method of Study:
Effects of Bacterial Roles on the Formation of Disinfection By-Products Under Metal Induction and Biofilm Response to Antibiotics
(2019-05-01)
This dissertation had studied the differences between chemical and biological reaction of DBP production and provide a mechanistic understanding for the sources of precursors under which DBP formation varies. This study ...
Study examining MDC units couple treating carbohydrate base stream waste and artificial seawater
(2014-05)
Investing the biomass energy production in microbial desalination cells (MDCs) to drive another process like desalination has gained a great attention these days pushing researchers to try to unveil the limiting factors ...
Strategies for compliance with stage 2 Disinfectants and Disinfection Byproducts Rule for surface water treatment facilities in northeastern Oklahoma
(2012-07)
Scope and Method of Study: The Environmental Protection Agency (EPA) recently created new regulations that better protect human health but that also make achieving compliance more difficult for existing water treatment ...
Direct observations on microstructure evolution of cement systems at early ages
(2017-05)
There is limited understanding of the mechanisms or direct measurements of cement paste hydration, as the main component that determines mechanical, durability, and rheology properties of concrete. This dissertation uses ...
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 ...
Aggregate proportioning for slip formed pavements and flowable concrete
(2015-07)
This is an investigation into developing a relationship between aggregate proportioning and the workability of concrete for slip formed pavements and flowable concrete applications. Workability tests were developed for ...
