Performance tests on asphalt mixtures at multiple temperatures and development of pavement temperature maps
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Thermal cracking and rutting are deteriorations that significantly affect asphalt pavements in the United States (US). Thermal cracking is a prevalent problem...
Blast resistant forced entrty [sic] steel stud wall design
(University of Missouri--Columbia, 2005)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the threat of terrorist attacks, a series of tests has been conducted, on different forced entry wall configurations, to determine the static resistant function...
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 ...
Analytical study of the spectral-analysis-of-surface-waves method at complex geotechnical sites
(University of Missouri--Columbia, 2006)
The Spectral-Analysis-of-Surface-Waves (SASW) method is an accepted means of measuring shear wave velocity (VS). In some settings, SASW measurements have produced results that were inconsistent with results from other ...
Long-term sensing system for bridge piers
(University of Missouri--Columbia, 2009)
Structural instability of bridge piers resulting from scour or other natural hazards can lead to bridge collapse. As a result, a method of monitoring bridge piers is needed to evaluate long-term changes in structural ...
Axial load transfer in large scale physical model drilled shaft foundations
(University of Missouri--Columbia, 2019)
Drilled shaft foundations are a widely implemented type of deep foundation used to support heavy loads from superstructures such as buildings and bridges. Uncertainties exist in the axial load transfer behavior of drilled ...
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...
Process engineering to produce defined hierarchical structures of diatoms for wastewater polishing and micropollutant removal
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Diatoms are unicellular algae, which are among the most common types of phytoplankton. They are widespread in fresh water, oceans and soils with different sizes and morphologies...
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 ...
Modeling pedestrian crash severity in St. Louis using random forests and mixed logit techniques
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] The pedestrian-vehicle crashes in the City of St. Louis is a major concern due to the high magnitude of injuries and fatalities compared to Missouri's statewide...
Kinetics, mass transfer, and mass re-equilibrium for arsenate adsorption on iron oxide-based carbons
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Removal of arsenic (As) from drinking water sources is much needed worldwide, and small water treatment systems, such as point-of-use (POU) treatment, could be an effective...
Approaches for comparing the structural characteristics of different representations of transportation systems
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Collection and monitoring of locational information has considerably increased over the last decade as the value of location-based data has been realized by planning...
Environmental effects on subsurface defect detection in concrete without solar load
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the application of infrared (IR) thermography for the detection of subsurface damage in concrete. The deterioration of concrete as a result of corrosion...
Investigation of smart work zone technologies using mixed simulator and field studies
(University of Missouri--Columbia, 2020)
are drivers behave more uniformly after being educated about the meaning of signage displayed on the back of truck, and performance measured with signage would be more preferable than those without signage. Applications of statistics are extension of studies...
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. ...
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 ...
Exploring the impact of peracetic acid on bacterial regrowth and plasmid release and developing a novel whole-cell biosensor to monitor the expression of quorum sensing genes
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Peracetic acid (PAA or CH3COOOH) is a promising alternative to chlorine-based disinfectants for water and wastewater treatment due to its strong antimicrobial properties and low...
Tensile strength, shear strength, and effective stress for unsaturated sand
