Statistical and simulation methods for evaluating stationary and mobile work zone impacts
(University of Missouri--Columbia, 2018)
In 2014, nearly 10% of overall congestion on freeways was due to the presence of work zones (WZs), equivalent to 310 million gallons of fuel loss (FHWA, 2017a). In terms of safety, in the US, every 5.4 minutes, a WZ related ...
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 comparative numerical study on the failure evolution at different simulation scales
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] In computational mechanics, different numerical approaches and simulation scales may lead to different results. It is because each approach has its ...
Monitoring of an urban level spreader as part of the collaborative adaptive management process
(University of Missouri--Columbia, 2020)
Irregular flows, such as the high flows caused by stormwater runoff after a rain event are a major cause of stream impairment in urbanized watersheds. The Hinkson Creek CAM (Collaborative Adaptive Management) approach is ...
Simulator study of ridesharing pickup and dropoff area design and evaluation of benefits and applications of tethered surveillance drones (TSDS)
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Technology is reshaping transportation. An example is mobile apps that enable the growing ridesharing industry. When combined with another ...
Smartphone-based molecular sensing for advanced characterization of asphalt concrete materials
(University of Missouri--Columbia, 2018)
Pavement systems deteriorate with time due to the aging of materials, excessive use, overloading, climatic conditions, inadequate maintenance, and deficiencies in inspection methods. Proper evaluation of pavement conditions ...
GIS-based, python modeling of the spatial and temporal distribution of water on the landscape for wetlands decision making
(University of Missouri--Columbia, 2020)
Wetlands provide many benefits for humans and the natural environment, but land use changes have reduced their number and areal extent. Interest has grown in examining surface water distribution both spatially and temporally, ...
Estimating the rock mass modulus of Missouri shale using pressuremeter tests
(University of Missouri--Columbia, 2017)
Rock mass modulus can be a useful property in the design of foundations. Rock mass modulus is defined as the stress strain response of a rock mass in-situ. The stress strain response of the rock mass can be estimated by ...
Dynamic response of cold-formed steel roof trusses subject to blast load
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The popularity of cold-formed steel building components has seen rapid growth in recent years due to its low cost, high strength, and ability to ...
Ultrasonic measurement of stress in steel and concrete
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Advancements in ultrasonic technology may lead to the ability to directly determine stress (strain) in steel and concrete members through measurement ...
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 ...
Removal of hexavalent chromium and sulfamethazine by green zero valent iron nanoparticles (NZVI)
(University of Missouri--Columbia, 2019)
A green and low-cost method for nZVI fabrication was developed in this thesis using FeCl3 as the source of iron and yerba mate (Ilex paraguariensis) extract as the reductant. The extract showed an impressive high content ...
Axial load transfer in large scale physical model drilled shaft foundations
