Non-destructive evaluation of wood utility poles using computed axial tomography imaging
(University of Missouri--Columbia, 2006)
Of the more than 130 million wooden utility poles in service, there are approximately 2 million that are replaced annually. A quick, yet accurate non-destructive method of evaluation of the in-service poles could provide ...
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 ...
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 ...
Remote health monitoring for asset management
(University of Missouri--Columbia, 2009)
of bridge conditions by key managers and engineers. The developed technology has the potential to identify hazardous conditions at a bridge site, such that managers and owners can be notified automatically and appropriate actions can be undertaken...
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 ...
Condition assessment of carbon fiber composites using raman spectroscopy
(University of Missouri--Columbia, 2009)
The goal of this research is to examine the potential of Raman spectroscopy as a method of condition assessment for carbon fiber composite materials. Carbon fiber composites are used in high performance situations such as ...
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 ...
Volume change and swelling pressure of expansive clay in the crystalline swelling regime
(University of Missouri--Columbia, 2008)
for smectite for crystalline swelling. With better knowledge of how microstructural swelling translates to macroscopic behavior, the geotechnical engineering community and industry will be more equipped to approach and resolve the several problems involving...
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 ...
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 ...
Evaluation of the service performance of an innovative precast prestressed concrete pavement
(University of Missouri--Columbia, 2009)
Precast prestressed concrete pavement (PPCP) is the product of an optimization of conventional materials coupled with economical fabrication and transportation means to create a product that exceeds the performance and ...
Arsenic rejection by membrane processes : model development and application
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] This study investigated the rejection of arsenic by several nanofiltration and inorganic clay membranes. Laboratory-scale experiments were conducted ...
Sorption and leaching characteristics of heavy metals in artificial soil
(University of Missouri--Columbia, 2006)
strategy. Materials at the site include an organic-rich O-horizon (yard waste and biosolids) overlying a mineral-rich C-horizon (CKD and coal ash) to simulate a natural residual soil profile. A laboratory investigation of the general engineering, sorptive...
Data uncertainty in bridge management
(University of Missouri--Columbia, 2006)
The effectiveness of bridge management decisions is based on the quality of data, and the data collected has some amount of uncertainty, which may impact management decisions. This document describes a two-part procedure ...
Low strength wastewater treatment using emerging anaerobic treatment processes
(University of Missouri--Columbia, 2019)
complex organic matter to ensure a successful operation. To treat the sulfate-containing low-strength wastewater, we proposed a newly designed anaerobic microbial fuel cell (MFC) system that could be used to produce electricity and remove sulfate...
Evaluation of prestress losses in an innovative prestressed precast pavement system
(University of Missouri--Columbia, 2006)
To date no streamlined user efficient concrete roadway rehabilitation method is in practice in the United States. However, the use precast pavement is being evaluated and successful projects in Georgetown, Texas, El Monte, ...
Metallic nanotoxicity to bacteria and bacteriophages
(University of Missouri--Columbia, 2010)
The inhibitory effort of two commonly used nanoparticles, silver nanoparticles (Ag NPs) and zinc oxide nanoparticles (ZnO NPs), on the growth of bacteria (E. coli) and bacteriophage (MS2) were evaluated using a turbidimetric ...
Load transfer in reticulated and non-reticulated micropiles from large-scale tests
(University of Missouri--Columbia, 2007)
Using micropiles for slope stabilization is a proven technique but there are many uncertainties with how load is transferred from the soil to the structural elements. A large-scale model was constructed to test model slopes ...
