Pattern recognition based microsimulation calibration and innovative traffic representations
(University of Missouri--Columbia, 2008)
Even though calibration techniques for traffic simulation abound, this dissertation presents the first mathematical formalization using representations and invariants. The calibration is defined succinctly over three levels ...
Point target interferometry as applied to the characterization of localized deformation features
(University of Missouri--Columbia, 2008)
Monitoring of ground deformation is a critical component of geotechnical engineering practice. This study investigated the application of synthetic aperture radar interferometry (InSAR), using point target analysis (IPTA) ...
Knowledge discovery and data mining from freeway section traffic data
(University of Missouri--Columbia, 2008)
Archived traffic-generated data (traffic flow, accident, work-zone, and weather data) from PR-18 in San Juan was examined by means of association mining and the KDD process. A total of six studies were developed and studied ...
Development of a large-scale traffic simulation model for hurricane evacuation : a case study of Virginia's Hampton Roads region
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Hurricanes are one of the most catastrophic events resulting in severe consequences including loss of life and property damage. Emergency management ...
Study of surface wave methods for deep shear wave velocity profiling applied in the upper Mississippi embayment
(University of Missouri--Columbia, 2008)
Surface wave methods have become an important tool for non-intrusively and inexpensively determining shear wave velocity (V [subscript-s]) profiles for many geotechnical earthquake engineering applications. The primary ...
Numerical analysis of pile group within moving soils
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] A coupled soil-pile interaction analysis method for pile groups within moving soil is proposed and implemented in a new computer program MU-PILE-GROUP. ...
Development of shear wave velocity profiles in the deep sediments of the Mississippi Embayment using surface wave and spectral ratio methods
(University of Missouri--Columbia, 2008)
The deep soils of the Mississippi Embayment in the central United States will have a significant influence on earthquake ground motions generated by the New Madrid Seismic Zone. The seismic properties of these soils, which ...
Comparative study of type 2 median crossovers and median u-turns
(University of Missouri--Columbia, 2008)
Many states use rural expressway median crossovers which provide for separation between the two opposing traffic lanes to manage the direct left turn movements between the expressways and cross roads. As the volume increases ...
Methodology for quantifying wetland landscape parameters for highway right of way decisions utilizing GIS
(University of Missouri--Columbia, 2008)
Wetlands are a type of habitat which forms an interface between aquatic and terrestrial ecosystems. A growing problem in the state of Missouri and around the nation is the loss of the natural wetlands due to the expansion ...
Replication of freeway work zone capacity values in a microscopic simulation model
(University of Missouri--Columbia, 2008)
Evaluating the traffic impacts of work zones is vital for any transportation agency for planning and scheduling work activity. Traffic impacts can be accurately estimated using microscopic simulation models due to their ...
Laboratory load tests of side shear for axially loaded piles
(University of Missouri--Columbia, 2008)
Results from the laboratory testing program suggest that HPX-piles have approximately 10 percent greater side shear capacity than conventional HP-piles, on average. Unit side shear and the side shear parameter [beta] for ...
Decision support for slope construction and repair activities: an asset management building block
(University of Missouri--Columbia, 2008)
The objective of this research was to develop a support system to facilitate appropriate decision making for construction, maintenance, and repair of earth slopes along transportation rights of way. The system was to be ...
Model-based simulations of the piercing process in piezo-ICSI
(University of Missouri--Columbia, 2008)
To develop a piezo intracytoplasmic sperm injection (piezo-ICSI) procedure without using mercury, the real physics behind the zona piercing must be understood. An effort has been made to formulate a three-dimensional model ...
Volume change and swelling pressure of expansive clay in the crystalline swelling regime
(University of Missouri--Columbia, 2008)
A significant amount of research has been carried out to characterize expansive clay behavior from either microstructural or macrostructural perspectives; however, there exists a current gap in our knowledge about the basic ...
