(University of Waterloo, 2019-05-21)It has been predicted that approximately 65% of the developing world and 85% of the developed world will be living in cities by 2050. Toronto, the largest city in Canada and the fourth largest in North America, is expected ... -
Usage of Interface Management System in Adaptive Reuse of Buildings
(MDPI, 2019-05)Adaptive reuse of buildings is considered a superior alternative for new construction in terms of sustainability and a disruptive practice in the current capital project delivery model for the renewal of today’s built ... -
The Use of Coagulation as a Pre-treatment to Ultra-filtration Membranes
(University of Waterloo, 2007-09-17)ABSTRACT With an increasing population density throughout the world and the current drive to provide fresh water to as many people as possible, innovative methods of providing safe drinking water are in very high demand. ... -
The Use of Risk Analysis Techniques to Determine the Probability of Producing Non-Compliant Drinking Water: Focusing on Dual Media Rapid Gravity Filtration
(University of Waterloo, 2006)The main goal of a drinking water treatment plant is to provide safe drinking water for its consumers. Historically, this was accomplished through monitoring the influent and effluent water quality to ensure that the ... -
Using AASHTOWare Pavement ME Design Tools to Evaluate Flood Impact on Concrete Pavement Performance
(University of Waterloo, 2019-08-21)The resilience of concrete pavement to flood impact has remained positive based on previous experimental investigations and overtime recommended as a pre-flood adaptation strategy in countries such as Australia and the ... -
Using Finite Element Modeling to Gain Insights into the Mechanics of Wound Healing in Drosophila
(University of Waterloo, 2013-01-25)Although it is not difficult to observe the healing of induced wounds in animal embryos, mapping the forces that drive lesion closure has proved challenging. Laser microsurgery, Atomic Force Microscopy (AFM) and other ... -
Using Machine Learning to Understand the Hydrologic Impacts of Permafrost Thaw-Driven Land Cover Change
(University of Waterloo, 2023-04-25)Discontinuous permafrost regions are experiencing a change in land cover distribution as a result of permafrost thaw. In wetlands interspersed with discontinuous permafrost, climate change is particularly problematic because ... -
Using Microsimulation to Estimate the Impact of Transportation Improvements and Operational Policy Changes on Travel Time Reliability
(University of Waterloo, 2017-01-16)Traditionally, traffic engineers have designed roadway networks and operational strategies to manage congestion and minimize delays during the peak demand period for some “average” or “typical” day. However, increasingly, ... -
Using Road Weather Information Systems (RWIS) to optimize the Scheduling of Load Restrictions on Northern Ontario's Low-Volume Highways
(University of Waterloo, 2007-09-18)Covering the Northern part of the Province, Ontario’s low-volume roads provide a link from remote resource areas to markets. Thus, preserving this transportation asset from the two main sources of pavement deterioration, ... -
Using Transit AVL/APC System Data to Monitor and Improve Schedule Adherence
(University of Waterloo, 2010-04-29)The implementation of automatic transit data collection via Automatic Vehicle Location (AVL) and Automatic Passenger Counting (APC) systems provides an opportunity to create large, detailed datasets of transit operations. ... -
The Utility of Using Multiple Conceptual Models for the Design of Groundwater Remediation Systems
(University of Waterloo, 2014-04-30)The design of pump and treat systems for groundwater remediation is often aided by numerical groundwater modelling. Model predictions are uncertain, with this uncertainty resulting from unknown parameter values, model ... -
Utilizing the Canadian Long-Term Pavement Performance (C-LTPP) Database for Asphalt Dynamic Modulus Prediction
(University of Waterloo, 2013-04-05)In 2007, the Mechanistic-Empirical Pavement Design Guide (MEPDG) was successfully approved as the new American Association of State Highway and Transportation Officials (AASHTO) pavement design standard (Von Quintus et ... -
Validation Methodologies for Construction Engineering and Management Research
(University of Waterloo, 2013-07-19)Validation of results is an important phase in the organization of a researcher’s work. Libraries and the internet offer a number of sources for guidance with respect to conducting validation in a variety of fields. However, ... -
Valuation of in-situ Building Materials for Resource Recovery
(University of Waterloo, 2024-02-08)The construction industry is among the largest contributors to global raw material consumption and is responsible for 40% of annual greenhouse gas emissions. Recovery of building materials at the end of a building's life, ... -
Vapour Diffusion Control in Framed Wall Systems Insulated with Spray Polyurethane Foam
