Acceptance Criteria for Ultrasonic Impact Treatment of Highway Steel Bridges
(University of Waterloo, 2012-08-30)The need for rehabilitation of bridges has become a critical challenge due to aging and an increase in traffic loads. Many of these bridges are exceeding their design fatigue life. Since many of these bridges are structurally ... -
Acoustic Monitoring for Leaks in Water Distribution Networks
(University of Waterloo, 2020-04-21)Water distribution networks (WDNs) are complex systems that are subjected to stresses due to a number of hydraulic and environmental loads. Small leaks can run continuously for extended periods, sometimes indefinitely, ... -
Acquiring Multimodal Disaggregate Travel Behavior Data Using Smart Phones
(University of Waterloo, 2013-01-25)Despite the significant advances that have been made in traffic sensor technologies, there are only a few systems that provide measurements at the trip level and fewer yet that can do so for all travel modes. On the other ... -
Active Acoustics for Monitoring Unreported Leaks in Water Distribution Networks
(University of Waterloo, 2021-09-08)Water distribution networks (WDNs) are critical infrastructure elements conveying water through thousands of kilometers of pipes. Pipes - one of the most critical elements in such systems - are subjected to various structural ... -
Activity Analysis for Continuous Productivity Improvement in Construction
(University of Waterloo, 2010-08-30)In the construction industry, onsite labour is one of the most variable and costly factors which affect project profits. Due to the variable nature of construction labour and its correlation with profits, construction ... -
Activity-Based Data Fusion for the Automated Progress Tracking of Construction Projects
(University of Waterloo, 2012-03-09)In recent years, many researchers have investigated automated progress tracking for construction projects. These efforts range from 2D photo-feature extraction to 3D laser scanners and radio frequency identification (RFID) ... -
Adaptable Three Dimensional System for Building Inspection Management
(University of Waterloo, 2012-08-30)Sustaining the safety and operability of civil infrastructure assets, including buildings, is a complex undertaking that requires a perpetual cycle involving inspection, and further decisions for renewal fund allocation. ... -
The Adaption of a Rapid Screening Test to Rank the Corrosion Behaviour of Stainless Steel Reinforcing Bars in Concrete
(University of Waterloo, 2018-08-21)The costs associated with aging reinforced concrete infrastructure in Ontario continue to rise as highway infrastructure, such as bridges, continuously deteriorate. The use of de-icing salts on these bridges in the winter ... -
Adaptive Traffic Signal Optimization Using Bluetooth Data
(University of Waterloo, 2017-10-23)Traffic congestion continues to increase in urban centers causing significant economic, environmental, and social impacts. However, as urban areas become more densely developed, opportunities to build more roadways decline ... -
Addressing the Uncertainty Due to Random Measurement Errors in Quantitative Analysis of Microorganism and Discrete Particle Enumeration Data
(University of Waterloo, 2010-10-08)Parameters associated with the detection and quantification of microorganisms (or discrete particles) in water such as the analytical recovery of an enumeration method, the concentration of the microorganisms or particles ... -
Addressing Uncertainty in Health Impacts of Air Pollution under Climate Change Mitigation
(University of Waterloo, 2022-01-18)Simulations to evaluate climate policy take a lot of time, but little evidence exists to say how long is enough, especially for policy impacts related to air pollution. Air pollution and climate change are the two leading ... -
An Advanced Construction Supply Nexus Model
(University of Waterloo, 2013-04-22)The complex and challenging process of construction supply chain management can involve tens of thousands of engineered components, systems, and subsystems, all of which must be designed in a multi-party and collaborative ... -
Advanced Traffic Signal Control Using Bluetooth Detectors
(University of Waterloo, 2018-03-14)Traditionally signal timing plans are developed for expected traffic demands at an intersection. This approach generally offers the best operation for typical conditions. However, when variation in the traffic demand occurs, ... -
