The overall objective of this thesis is to develop a package of high-resolution, non-invasive experimental and numerical approaches to observe in situ pore-scale geometry modification due to colloid deposition, and quantitatively predict its effects on the large-scale transport properties of the porous medium. High-energy synchrotron-based X-ray difference micro-tomography (XDMT) was...
An accurate knowledge of the engineering properties of rocks is crucial for a variety of geomechanical problems, ranging from wellbore stability to failure in rock slopes, underground excavations, and crustal faults. While strength and deformation properties are usually obtained from a limited number of in situ and/or laboratory tests, their...
The purpose of the dissertation is to develop a framework for equilibration of activity-trip chain demand in an integrated system of activity scheduling and travel choices within a dynamic network equilibrium framework. Activity-based modeling systems generate detailed activity chain schedules for individuals, which have to be assigned to transportation networks....
