Development of a Framework to Evaluate Asphalt Binder and Plant Produced Asphalt Mixes for Acceptance in Canada
(University of Waterloo, 2022-05-05)Asphalt binder, sometimes referred to as asphalt cement binder, or asphalt cement, is the binder that holds the aggregates together in asphalt mixes for asphalt concrete pavements. In Canada, asphalt binder properties are ... -
Novel SMA Dowel Connections for Seismically Resilient Timber Buildings
(University of Waterloo, 2022-05-03)The trend towards sustainable construction practices has led to a growing demand for mid- to high-rise mass timber structures and a growing interest in their behaviour during earthquakes. Due to the brittle nature of wood, ... -
A Risk-Based Decision Support Framework for Railway-Highway Grade Crossing Closures
(University of Waterloo, 2022-05-03)Reducing the risk of collisions between trains and vehicles at railway-highway grade crossings is a high priority safety strategy set by many governments and railway authorities. To achieve this goal, one of the main ... -
Fatigue Design and Behaviour of Carburized Steel
(University of Waterloo, 2022-05-02)Steel is an essential component used in infrastructure, automobiles, machines and many other areas due to its low cost and high tensile strength. Carburization is a heat treatment process commonly used to harden and ... -
Effect of Post-Rolling Surface Condition on the Corrosion Performance of UNS 32205 Stainless Steel Rebar
(University of Waterloo, 2022-04-29)During the winter season, ice accumulation on roads and sidewalks is a major problem and poses a hazard to road users. The most common method of addressing this issue is by applying de-icing salts or spraying a brine ... -
Unsupervised Methods for Condition-Based Maintenance in Non-Stationary Operating Conditions
(University of Waterloo, 2022-04-28)Maintenance and operation of modern dynamic engineering systems requires the use of robust maintenance strategies that are reliable under uncertainty. One such strategy is condition-based maintenance (CBM), in which ... -
Integration of 3D Feedback Control Systems for Fabrication of Engineered Assemblies for Industrial Construction Projects
(University of Waterloo, 2022-04-26)A framework and methods are presented in this thesis to support integration of 3D feedback control systems to improve dimensional conformance during fabrication of engineered assemblies such as process piping, structural ... -
Analysis of Passive Magnetic Inspection Signals Using the Haar Wavelet and Asymmetric Gaussian Chirplet Model (AGCM)
(University of Waterloo, 2022-04-07)Nowadays, Non-Destructive Testing (NDT) techniques are an essential foundation of infrastructure retrofit and rehabilitation plans, mainly due to the huge amount of construction, as well as the high cost of demolition and ... -
Confirming the need for virus disinfection in municipal subsurface drinking water supplies
(Elsevier, 2019-06)Enteric viruses pose the greatest acute human health risks associated with subsurface drinking water supplies, yet quantitative risk assessment tools have rarely been used to develop health-based targets for virus treatment ... -
Recognizing Structural Nonidentifiability: When Experiments Do Not Provide Information About Important Parameters and Misleading Models Can Still Have Great Fit
(Wiley, 2020-02)In the quest to model various phenomena, the foundational importance of parameter identifiability to sound statistical modeling may be less well appreciated than goodness of fit. Identifiability concerns the quality of ... -
Early Flame Detection System Using Real-Time Machine-Vision and Image Analysis
(University of Waterloo, 2022-02-04)From 2010 to 2019, 110,811 fires with losses have been reported to the Office of Fire Marshall and Emergency Management in Ontario. In The USA, the local fire departments responded to 1,338,500 fires in 2020. These fires ... -
The pie sharing problem: Unbiased sampling of N+1 summative weights
(Elsevier, 2022-02)A simple algorithm is provided for randomly sampling a set of N+1 weights such that their sum is constrained to be equal to one, analogous to randomly subdividing a pie into N+1 slices where the probability distribution ... -
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 ... -
