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) ...
Nitrification enhancement in lagoons using fixed film media
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Lagoons, commonly used in municipal wastewater treatment, are limited in their ability to treat wastewater due to limitations in the process and ...
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 ...
Blast resistant design for roof systems
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The design of structures to resist explosive loads has become more of a concern to the engineering community. This research focuses on the design ...
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 ...
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 ...
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 ...
Use of fluorescence excitation emission matrix spectroscopy for water and wastewater characterization
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Excitation Emission Matrix Spectroscopy (EEMS) has the potential to be used for the real time monitoring of environmental effects on water and ...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
Occurrence and modeling of THMS and HAA formation in drinking water
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Trihalomethanes (THMs) and haloacetic acids (HAAs) are two of the largest classes of disinfection by-products (DBPs) during chlorination in drinking ...
Safety evaluation of large truck-passenger vehicle interactions and synthesis of safety corridors
(University of Missouri--Columbia, 2007)
Insights into the nature of large truck-passenger car interactions and the understanding of safety corridors can lead to improvements in the safety and efficiency of freeway operations. One main contribution of this thesis ...
Sensor characterization for long-term remote monitoring of bridge piers
(University of Missouri--Columbia, 2007)
Structural instability of bridge piers resulting from scour or other natural hazards can lead to bridge collapse. A monitoring system that analyzes bridge pier behavior could prevent this type of failure by detecting ...
Characterization of disinfection by-product precursors from Missouri streams
(University of Missouri--Columbia, 2007)
The NOM contained in drinking water sources reacts with Cl2 to generate THMs and HAAs. THMs and HAAs are regulated by EPA because they pose a health hazard. The nature of the DBP precursors is complex and not well understood. ...
Development and evaluation of innovative iron-containing porous carbon adsorbents for arsenic removal
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Arsenic is of serious concern because of its marked negative impacts to human health. Of the various sources of arsenic in the environment, drinking ...
