Nonnormality in the seismic response of primary-secondary systems
Response nonnormality is investigated for a yielding primary structure and a linear secondary system (P-S) subjected to a normally distributed ground acceleration. The nonlinearity considered is bilinear hysteretic (BLH) ...
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 ...
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 ...
Dynamic response of force-excited systems
The elastic and inelastic responses of the force-excited single-degree-of-freedom (SDOF) systems are investigated from the gross characteristics of forcing functions such as the frequency content, the integrals and the ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Iterative determination of spar lines static equilibrium and improved dynamic modeling by fractional derivatives
Polyester mooring systems are used as permanent systems of floating production systems and offshore structures. Compared to other mooring systems, polyester has a highly non linear behavior, thus complicating the overall ...
Kinetics of core material dissolution in the presence of inhibitors for application in geologic carbon sequestration
With increased attention on rising carbon dioxide levels, carbon capture and sequestration (CCS) has become a commonly proposed solution. CCS has been studied for several decades, but is being researched more and more ...
