POROVISCOELASTICITY AND ANALYTICAL SOLUTIONS OF SELECTED PROBLEMS IN ENGINEERING
(2011)
This study provides newly-derived analytical poroviscoelastic solutions for a number of practical and important engineering problems with various levels of material anisotropy: laboratory and field testing of cylinders ...
CHARACTERIZATION OF CEMENTITIOUSLY STABILIZED SUBGRADES FOR MECHANISTIC-EMPIRICAL PAVEMENT DESIGN
(2010)
Pavements are vulnerable to subgrade layer performance because it acts as a foundation. Due to significant increase in truck traffic, pavement engineers are challenged to build more strong and long-lasting pavements. To ...
Plant uptake, time trends, and natural attenuation of selected metals in an abandoned mining district
(2011)
Soils, vegetation, and water in the abandoned Tri-State mining district are contaminated by lead, zinc, and other metals. To investigate trends in lead and zinc concentrations in the environment for past periods when little ...
EXPERIMENTAL ANALYSIS FOR STEEL CONGESTION RELIEF IN CONCRETE STRUCTURES UNDER MONOTONIC AND SEISMIC LOADS
(2011)
Since the beginning of this PhD research, the author has endeavored to determine how to resolve the issues involving steel congestion in reinforced concrete (RC) structures. Three potential solutions to this problem were ...
DIMENSIONAL STABILITY OF CONCRETE SLABS ON GRADE
(2011)
Drying shrinkage is one of the major causes of cracking in concrete slabs on grade. The moisture difference between the top and bottom surface of the slabs causes a dimensional or "shrinkage" gradient to develop through ...
Laboratory and Field Assessment of Chemically-Stabilized Subgrade Moduli under Compressive and Flexural Loading
(2016-12-07)
The design and quality of the chemically-stabilized subgrade (CSS) layer have a vital role in the overall performance of the asphalt pavement. Uniform compaction of the CSS layer to the desired level can assure the amenability ...
Modeling Rates and Energetics of Anaerobic Hydrocarbon Biodegradation
(2012)
Hydrocarbons are ubiquitous in the environment, originating from both natural and refined sources and are an important class of compounds because of their role in the world's energy requirements, their toxicity, and their ...
AN INVESTIGATION OF SUSTAINABLE FLUORIDE WATER TREATMENT TECHNOLOGIES WITH A FOCUS ON ETHIOPIA
(2014)
Human consumption of unsafe drinking water from an unimproved source is a global issue affecting approximately 748 million people worldwide. While this number has been decreasing in recent years, an additional 1.2 billion ...
A SUGGESTED DESIGN APPROACH FOR BUILT-UP COLD-FORMED COLUMNS BASED ON RESEARCH USING NONLINEAR FINITE ELEMENT METHOD
(2011)
A deficiency of the 2007 AISI specification, Sections C4 and D1.2 for built-up, coldformed
Advances using the ADCIRC hydrodynamic model: Parameter estimation and aspects of coupled hydrologic-hydrodynamic flood inundation modeling
(2011)
The ADCIRC hydrodynamic model has been used extensively for coastal modeling applications over the last twenty years. Within the last decade, modeling of hurricane storm surge has become one of its principal applications. ...
