Development and applications of novel nanostructured materials in water treatment : adsorption, filtration, and reaction
(University of Missouri--Columbia, 2021)
solutions. Adsorption on hematite and IOGO(25 %) at 25 [degrees]C, pH 7, and 1 mM NaNO3 showed 76 % of As(V) removal within the first 5 minutes and 95 % at 40 minutes. As(V) adsorption efficiency increased with increase GO loading; while, this efficiency...
Influence of ground tire rubber on stone mastic asphalt mixtures and preliminary sustainability studies on rubber-modified asphalt pavements
(University of Missouri--Columbia, 2021)
to assess GTR as viable means modification suitable for SMA pavements, with respect to the extreme climatic conditions of Missouri. To achieve this, two GTR-modified SMA mixes with 10 percent modification were compared against an unmodified SMA mix. A suite...
Developing a modern recycled mix design and automatic pavement monitoring system
(University of Missouri--Columbia, 2021)
, and Convolution Neural Network (CNN) was used to train the Hamburg wheel track model on 10,000 data points. A database containing a comprehensive collection of Hamburg and DC(T) tests results were used to develop the machine learning-based prediction models...
Experimental investigation of the Horizontal-to-Vertical Spectral Ratio (HVSR) method for estimating depth of bedrock in Central Missouri
(University of Missouri--Columbia, 2022)
reliable relationship of depth to bedrock could be developed for the University of Missouri (MU) campus using the HVSR method alone without shear wave velocity measurements. In total, 65 HVSR measurements were performed around the MU campus over...
Modeling transportation impacts of natural disasters
(University of Missouri--Columbia, 2021)
. The study found that several factors contribute to evacuees choosing a freeway over other routes. In the descending order of importance (i.e., marginal effects), these factors are willing to use the official recommended route, living in a single-family...
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 ...
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 ...
Evaluation of use of dry-process rubber modification in asphalt mixtures
(University of Missouri--Columbia, 2020)
This study explores four different facets of using dry-process rubber modification in asphalt mixtures. The first investigation was motivated by the need to understand the cracking mechanism prevalent in the dry-process ...
New methods for interpret the ultimate axial load capacity of driven square concrete piles
(University of Missouri--Columbia, 2020)
Piles are usually designed using analytical methods, empirical models, or dynamic formulas. Because of the uncertainties involved in the analysis and design of pile foundations, it has become customary, and in many cases ...
Detection and quantification of delamination in concrete via time-lapse thermography with machine learning
(University of Missouri--Columbia, 2021)
This study developed a framework to automatically extract sub-surface defects from time-lapse thermography (TLT) images of reinforced concrete bridge components. Traditional approaches for processing TLT data typically ...
A GIS protocol for enhancing the selection of agricultural runoff sampling locations and predicting the locations of potential pollutant transport in the upland environment
(University of Missouri--Columbia, 2022)
in Mendeley Data (doi: 10.17632/wdjzftxyfd.1)....
