Cured-in-Place Pipe Pressure Liner Experimental Study
(University of Waterloo, 2023-04-06)Long-term mechanical properties are critical parameters for the design and performance of thermoset Cured-in-Place Pipe (CIPP) gravity and pressure liners. These liners have been used extensively across North America; ... -
Data Fusion for Materials Location Estimation in Construction
(University of Waterloo, 2010-04-29)Effective automated tracking and locating of the thousands of materials on construction sites improves material distribution and project performance and thus has a significant positive impact on construction productivity. ... -
Decentralized Ambient System Identification of Structures
(University of Waterloo, 2013-05-22)Many of the existing ambient modal identification methods based on vibration data process information centrally to calculate the modal properties. Such methods demand relatively large memory and processing capabilities to ... -
Decision Support System for Value-Based Evaluation and Conditional Approval of Construction Submittals
(University of Waterloo, 2010-07-15)To ensure compliance with specifications during construction, a formal review process, called the submittals process is typically implemented, whereby the contractor is required to submit proposals for materials, equipment, ... -
Deep Reinforcement Learning Models for Real-Time Traffic Signal Optimization with Big Traffic Data
(University of Waterloo, 2021-05-19)One of the most significant changes that the globe has faced in recent years is the changes brought about by the COVID19 pandemic. While this research was started before the pandemic began, the pandemic has exposed the ... -
Delay and Queue Length Estimation at Signalized Intersections Using Archived Automatic Vehicle Location and Passenger Count Data from Transit Vehicles
(University of Waterloo, 2015-05-19)Signalized intersections are typically the capacity bottlenecks within urban road networks. The performance of signalized intersections is typically quantified on the basis of average vehicle delay and maximum queue lengths. ... -
Deployable Vibration Control Systems for Lightweight Structures
