Modeling, analysis, and comparative study of several seismic passive protective systems for structures
This thesis is concerned with passive control systems for seismic protection of building structures, with special emphasis on elastomeric bearings, viscous dampers and tuned mass dampers. Both mathematical modeling and ...
Integration of a surcharged pipe model and an overland flow model for flood prediction in a highly urbanized area
Two models were incorporated to evaluate the hydrologic and hydraulic behavior of the Harris Gully watershed in Houston, Texas. A HEC-1 model was created and calibrated to three historical storms for average errors of 6% ...
Developing an introductory civil engineering course
A new course designed to introduce freshmen to civil engineering and to give non-engineers a taste of engineering was developed and taught. The course is divided into four sections (demand, design, construction, and effects) ...
Evaluation of fuel ethanol releases in a pilot-scale aquifer tank: Source dynamics, NAPL migration and microbial community response
Ethanol is playing a key role in current discussions on energy, agriculture, taxes and the environment. This work addresses the potential environmental impacts and behavior of subsurface fuel-ethanol releases. A continuous-flow ...
Dynamic response of hazardous liquid-waste storage tanks used in nuclear facilities
This dissertation presents a comprehensive study of the dynamic response of storage tanks containing high-level radioactive wastes in nuclear facilities. Of the many issues that are peculiar to these systems, four important ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Soil-structure interaction effects of simple structures supported on rectangular foundations
This thesis deals with the effects of soil-structure interaction, both kinematic and inertial, on the responses of seismically excited rectangular foundations and simple structures supported on such foundations. The ground ...
Settling characteristics of fractal aggregates
The settling velocity of aggregates found in engineered water and wastewater treatment facilities are usually assumed to follow Stokes' law. These particles, however, are typically porous and may be fractal in nature. As ...
Bacteria and fullerene: The microbial response to fullerene water suspensions
The current nanotechnology boom necessitates timely research into the health and environmental impacts of nanomaterials to enhance their eco-responsible manufacture, use, and disposal. Using the water-insoluble C60 as a ...
