Controlled study of ground-based interferometric radar for rockfall hazard monitoring
(University of Missouri--Columbia, 2015)
The ability to detect small and localized movements of geotechnical facilities is important monitoring and early-warning hazard detection. Current deformation monitoring technology is limited in its ability to both scan ...
Change in sludge settling and filtration properties and membrane fouling trends in MBR activated sludge systems operated at different solids and hydraulic retention times
(University of Missouri--Columbia, 2014)
Membrane bioreactor (MBR) activated sludge process is increasingly used in wastewater treatment due to its excellence in solid-liquid separation and superior effluent quality, smaller bioreactor volume and foot print. ...
Development of a portable total-stress measurement instrument
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This research explores the application of ultrasonic stress measurement (USM) technologies to assess stress levels in gusset plates with the development ...
Recent efforts on model-based simulation of engineering problems : multiphysics and multiphase interactions
(University of Missouri--Columbia, 2016)
Simulation-Based Engineering Science (SBES) is playing a more important role in gaining new knowledge and providing guidance for engineering activities, in particular, in the fields in which time scale and/or spatial scale ...
Molecularly imprinting polymer sensor for the detection of testosterone and endocrine disrupting chemicals in environmental and biomedical applications
(University of Missouri--Columbia, 2021)
Molecular imprinting is one of the promising techniques that have been used recently to detect trace contaminants in aqueous solution. This technique is based on the fact that the target compound is present during the ...
Improved design of highway bridge fingerplate expansion devices
(University of Missouri--Columbia, 2021)
Fingerplate expansion joints are used in highway bridges to account for large movements and rotations of two bridge deck slabs. These joints experience may premature failure that affects the structural integrity of the ...
Enhancing the mechanica and durability properties of cement mortars by using alumina nanocoating on carbon nanofibers
(University of Missouri--Columbia, 2021)
This thesis presents a comparative study on using nanocomposite of aluminum oxide (Al2O3) nanocoating on carbon nanofibers (CNFs) and bare CNFs for enhancing the cement mortars mechanical properties, durability under ...
Effect on water absorpion and outdoor weathering on emerging polymer interlayers
(University of Missouri--Columbia, 2021)
Laminated glass windows are becoming increasingly popular in the structures industry. Because of this, new polymer interlayer materials are being developed to better serve the purposes of building design, rather than ...
Multi-objective network optimization: models, methods, and applications
(University of Missouri--Columbia, 2021)
There can be an array of planning objectives to consider when identifying alternatives for using, modifying, or restoring natural or built environments. In this respect, multi-objective network optimization models can ...
Influence of ground tire rubber on stone mastic asphalt mixtures and preliminary sustainability studies on rubber-modified asphalt pavements
(University of Missouri--Columbia, 2021)
Over the last few decades, the use of Stone Mastic Asphalt (SMA) has been adopted by several states in the U.S. as a specialty mix for high-traffic volume purposes. Extensive research on these mixes has revealed its unique ...
Foundation design: presumptive vs. measured strength of the burlington limestone
(University of Missouri--Columbia, 2021)
Much of the main campus of the University of Missouri-Columbia is underlain by Burlington limestone. When new structures are built on campus, often the foundations of the structure must be set into bedrock, as it provides ...
Experimental evaluation of laminated glass interlayer polymers at various strain rates and temperatures
(University of Missouri--Columbia, 2020)
The use of blast-resistant glazing, such as laminated glass in buildings can greatly reduce, if not eliminate, the hazard of flying glass shards. In a failure event, fractured glass shards adhere to the polymer interlayer, ...
An evaluation of waste plastic in asphalt pavement towards a circular economy
(University of Missouri--Columbia, 2020)
Incorporating waste plastic into asphalt pavement is an evolving recycling strategy based on a circular economy approach. Dow has cooperated with MU to use optimal recycle plastic to target better pavement performance with ...
Development and applications of novel nanostructured materials in water treatment : adsorption, filtration, and reaction
(University of Missouri--Columbia, 2021)
Nanomaterial-based adsorbents and photocatalysts have gained increasing attention in the applications of water and wastewaters treatment due to their attractive properties and strong adsorption capabilities for a wide range ...
Time-dependent response of reinforced concrete elements near collapse
(University of Missouri--Columbia, 2021)
Reinforced Concrete (RC) structures may experience collapse under high levels of sustained gravity load. High levels of load are possibly due to errors in design and construction, material degradation, and abnormal loading. ...
Reliability-based analysis of settlements of shallow foundations on cohesionless soils
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI-COLUMBIA AT REQUEST OF AUTHOR.] Although settlements of foundations on cohesionless soils usually are small, it is important to be able to predict them because the primary ...
