Unraveling the relationship between trip chaining and mode choice using Structural Equation Models
DownloadSpring 2010
Trip chaining and mode choice are two important travel behavior decisions in activity-based travel demand modeling system. The hierarchy of these two decisions influences model’s predictive capability and policy sensitivity. This thesis is aimed at investigating the hierarchical relationship...

Unsaturated soil property functions are necessary for numerical modeling of geotechnical engineering problems including transient seepage or contaminant transport involving unsaturated soils such as tailings or mine wastes. The accuracy of the input of material properties significantly influences...

Unsteady characteristics of three-dimensional turbulent flow with separation in an asymmetric diffuser
DownloadFall 2017
A great number of studies have been undertaken to understand separated turbulent boundary layers (TBLs) due to its importance in the performance, design and control of many engineering systems (Hal 2000). Flow separation has a complicated three-dimensional nature in many flow configurations...
