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 ...
Polysulfone ultrafiltration membranes impregnated with silver nanoparticles show improved biofouling resistance and virus removal
Biofouling and virus penetration are two significant obstacles in water treatment membrane filtration. Biofouling reduces membrane permeability, increases energy costs, and decreases the lifetime of membranes. In order to ...
A mechanistic study on the coupled organic and colloidal fouling of nanofiltration membranes
The more wide-spread use of nanofiltration membranes in industrial applications is dependent upon understanding the fouling behavior of representative feed solutions, such as complex suspensions with both organic and ...
Response and first-passage statistics of nonlinear structural models under evolutionary stochastic loads
In the first half of the thesis, a novel approach is developed for determining the response of a lightly damped nonlinear single-degree of freedom system to a random excitation with an evolutionary broad-band power spectrum. ...
Efficient seismic fragility assessment of highway bridges on liquefiable soils
The increasing failure potential of U.S. highway bridges from aging and susceptibility to damage in extreme events, such as earthquakes, necessitates the development of efficient assessment tools to help infrastructure ...
Virus inactivation by silver doped titanium dioxide nanoparticles for drinking water treatment
UV disinfection of drinking water is becoming more common as water utilities attempt to control the formation of disinfection byproducts. While most organisms are readily inactivated by UV, certain viruses require a large ...
