Methods in Modelling of Composite Materials with Microstructure
(University of Waterloo, 2022-08-12)Composite material properties are dependent on their microstructure. To adequately model these materials, a revised formulation of elasticity that accounts for microstructural effects must be considered. Size dependent ... -
Micro- and Nanoplastics Removal through Drinking Water Treatment Processes: Insights from Published Investigations and Development of a Possible Regulatory Approach
(University of Waterloo, 2023-08-02)Micro- and nanoplastics (MNPs) have emerged as significant environmental pollutants with potential implications for human health. The presence of MNPs in freshwater bodies, such as lakes, rivers, and sometimes groundwater, ... -
Microcystin and Microcystis Destruction by Ozone in Drinking Water Treatment: Constraints and Effects
(University of Waterloo, 2016-07-14)Appropriate and effective drinking water treatment is critical to the protection of public health. Toxic cyanobacterial blooms are a globally increasing drinking water source quality-associated health risk as even very ... -
A Microeconomic Perspective to Infrastructure Renewal Decisions
(University of Waterloo, 2014-12-16)Under the prevailing financial constraints and rapid infrastructure deterioration, funding decisions for renewal (rehabilitation) projects have become large challenges for engineers and economists alike. However, existing ... -
Micromechanical Modelling of Polyethylene
(University of Waterloo, 2007-11-27)The increasing use of polyethylene in diverse applications motivates the need for understanding how its molecular properties relate to the overall behaviour of the material. Although microstructure and mechanical properties ... -
A Micromechanical Study of Undrained Granular Media Using Fluid-coupled Discrete Numerical Simulations
(University of Waterloo, 2018-12-06)Engineering behavior of saturated granular materials under rapid loading as during earthquakes is reasonably well explored empirically. Presently, theoretical models developed within concepts of classical soil mechanics ... -
Microscopic Overtaking Model to Simulate Two-lane Highway Traffic Operation and Safety Performance
(University of Waterloo, 2013-11-14)Rural two-lane highways make up a large portion of road networks around the world. The special geometric and traffic attributes of these highways pose special challenges to safety and traffic operation. In recent years, ... -
Mitigation of Climate Change Impacts on Runway Friction Kuujjuaq Airport
(University of Waterloo, 2014-04-17)In response to global climate change, Transport Canada has initiated a Climate Change Adaptation Study in order to provide an opportunity to improve knowledge of the impacts of climate change on transportation infrastructure ... -
A Model for Automated Construction Materials Tracking
(University of Waterloo, 2009-01-16)Materials management is a critical factor in construction project performance, particularly in the industrial sector. Research has shown that construction materials and installed equipment may constitute more than 50% of ... -
A Model for Implementing an Automated Change Management Process for Construction Mega-projects
(University of Waterloo, 2014-11-21)This thesis develops a model for implementing and continuously improving the automated change management process for construction megaprojects. Changes are inevitable in megaprojects. Their negative impact along with the ... -
Modeling Nutrient Legacies and Time Lags in Agricultural Landscapes: A Midwestern Case Study
(University of Waterloo, 2019-05-21)Land-use change and agricultural intensification have increased food production but at the cost of polluting surface and groundwater. Best management practices implemented to improve water quality have met with limited ... -
Modeling Safety Performance at Grade Crossing using Microscopic Simulation
(University of Waterloo, 2010-09-27)The analysis of grade crossing safety has long focused on vehicle-train crashes using statistical models based on crash data. The potential crashes generated by vehicle-vehicle rear-end conflicts have often been ignored. ... -
Modeling the Impact of Automated Materials Locating and Tracking Technology on the Construction Supply Network
(University of Waterloo, 2009-08-24)Ineffective materials and equipment management continues to be a leading cause of poor performance on construction projects today. Many of the problems arise as a result of the inability to convey information pertaining ... -
Modeling the Modal Shift towards a More Sustainable Transport by Stated Preference in Riyadh, Saudi Arabia
(MDPI, 2021-01-01)The need to gain a comprehensive understanding of road travelers’ choice of mode and their perceptions of using sustainable urban mobility modes have evolved to shape the form of future transport planning and policymaking. ... -
Modeling the Transportation of Select Trace Organic Contaminants from Source to Ecosystem in the Grand River
(University of Waterloo, 2021-06-02)Trace organic contaminants (TOrC) have been observed in waters downstream of wastewater treatment plants (WWTP) in the Grand River in southern Ontario, Canada. These contaminants have been correlated with adverse impacts ... -
