Field performance of instrumentation for monitoring effects of timber harvesting on water quality
(University of Missouri--Columbia, 2006)
in the Missouri Ozarks. The concept of a threshold event is introduced and defined as the amount of precipitation necessary under a specific set of environmental conditions to create collectable flow in the ephemeral channels. Precipitation and antecedent soil...
Automating traffic studies at modern roundabouts: a feasibility study
(University of Missouri--Columbia, 2007)
The modern roundabout is growing in popularity as an alternative intersection design, however it presents engineers a new quandary. At a traditional intersection, traffic movements may more easily counted given vehicle ...
Immersive work zone inspection training using virtual reality
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The Work Zone Safety and Mobility Rule (23 CFR [section] 630 Subpart J) established requirements and offers guidance to state transportation agencies for addressing the traffic...
Automated conflation framework for integrating transportation big datasets
(University of Missouri--Columbia, 2019)
technique; most of the existing system demands some sort of human involvement for the analysis to achieve higher accuracy. Through this work, an effort has been made to establish a fully automated process to conflate the road segments of Missouri state from...
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) ...
Traffic impact assessment and mitigation strategies for disruptions
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] This dissertation research focuses on modeling traffic conditions affected by disruptive events such as work zones, incidents, and hurricanes. Using a combination of field data...
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 ...
Federated multimodal simulators in transportation
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] As transportation involves a multiplicity of modes, there is a need to explore multimodal simulators in transportation and the integration of multimodal simulators to enable...
Instrumentation and early performance of an innovative prestressed precast pavement system
(University of Missouri--Columbia, 2006)
will give designers a significant advantage in improving pavement performance, decreasing construction time, and mitigating user costs. A pilot project, funded by FHWA, was created for a 1,000 ft (305 m) stretch of pavement on I-57 in southern Missouri...
Development and implementation of an underwater system for interface wave measurements
(University of Missouri--Columbia, 2005)
Measuring shear wave velocity profiles has become integral to geotechnical site investigation both on land and offshore. Obtaining accurate near-surface profiles in soft marine sediments can be expensive and time consuming ...
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 operational flexibilities...
First-principle simulation of blast barrier effectiveness for the development of simplified design tools
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Blast barrier walls have been shown to reduce the blast load on structures in most scenarios. Analysis of existing data for blast barrier response reveals that a need exists...
Simulation and optimization of low impact development for mitigating combined sewer overflows associated with climate change
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Modeling rainfall runoff can help to understand what is happening throughout the system, how can control of water to prevent flood, and how much the quality of runoff can change...
Nonlinear finite element modeling and characterization of guyed towers under severe loading
(University of Missouri--Columbia, 2007)
Guyed towers have been widely employed in the telecommunication industry. This study thus intends to improve the understanding and analysis of guyed towers that undergoes not only large deformation, but also large strain. ...
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 ...
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 ...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to quantify water quality in upland...
Safety modeling for two certain urban intersection types, HSM calibration, and crash severity distribution
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] According to several years' official crash data, a significant proportion of crashes happened at roadway intersections in Missouri. Of those intersection crashes, a large number...
Model-based simulations of the piercing process in piezo-ICSI
