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, ... -
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-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) ... -
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 ... -
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 ... -
Advancements in bender-element testing - frequency effects
(University of Waterloo, 2019-09-24)Modern building and bridge codes require seismic design of foundations and structures; for which, the evaluation of the soil’s response to dynamic loads is an important requirement in seismic design. The dynamic soil ... -
Advances in Hydraulic Fracture Simulation - Dynamic and Quasi-static Analysis
(University of Waterloo, 2019-03-05)Hydraulic fracturing (HF) is an effective technique for permeability enhancement of conventional and unconventional reservoirs. HF is performed by injecting a fluid (usually water-based), sand, and chemicals into a formation ... -
Advancing Microbial Risk Assessments of Subsurface Water Sources
(University of Waterloo, 2020-07-14)Source water microbial quality evaluations are essential for the selection, design, and management of drinking water supplies. As biological sciences and technology continue to advance, how these assessments are performed ... -
Algorithms for Geometric Optimization and Enrichment in Industrialized Building Construction
