Automating Water Capital Activities Using Naïve Bayes Classifier with Supervised Learning Algorithm
(University of Waterloo, 2021-08-09)Municipal governments have the responsibility to provide safe drinking water to residents. Maintaining water infrastructure systems to keep a certain level of service is a vital service. It is possible by assessing all ... -
Bayesian Inference of Stochastic Degradation Models: A Likelihood-Free Approach
(University of Waterloo, 2021-09-03)The structural integrity and system performance of large engineering systems are adversely affected by various forms of degradation mechanisms. Modeling of such mechanisms is accomplished by collecting degradation data ... -
Bayesian Nonparametric Dirichlet Process Mixture Modeling in Transportation Safety Studies
(University of Waterloo, 2017-08-08)In transportation safety studies, it is often necessary to account for unobserved heterogeneity and multimodality in data. The commonly used standard generalized linear models (e.g., Poisson-gamma models) do not fully ... -
Bedload sediment transport regimes of urban gravel-bed rivers under different management scenarios
(University of Waterloo, 2019-12-09)Watershed urbanization profoundly alters the hydrologic characteristics of urban rivers compared to their rural counterparts. This change in hydrologic conditions in combination with alterations to the sediment supply ... -
Behaviour of Post-Tensioned Slab Bridges with FRP Reinforcement under Monotonic and Fatigue Loading
(University of Waterloo, 2013-07-02)The introduction of fibre-reinforced polymers (FRPs) to the field of civil engineering has led to numerous research efforts focusing on a wide range of applications where properties such as high strength, light weight or ... -
Behaviour of Shear-Critical Reinforced Concrete Beams Strengthened with Fiber Reinforced Cementitious Mortar
(University of Waterloo, 2016-08-31)Extensive research has been conducted on strengthening of shear-critical reinforced concrete (RC) beams, particularly using fiber reinforced polymer (FRP) strengthening systems. This previous research has helped to better ... -
Best Productivity Practices Implementation Index (BPPII) for Infrastructure Projects
(University of Waterloo, 2013-08-22)According to the Nobel Prize winner Paul Krugman, “productivity isn’t everything, but in the long-run it is almost everything”. It is unfortunate that the productivity in the construction industry has lagged behind the ... -
BIM-Based Decision Support for Evaluation of Architectural Submittals during Construction
(University of Waterloo, 2014-07-15)Submittal review is a formal process that takes place after construction has begun. All materials, equipment, and processes submitted by a contractor are evaluated for compliance with specifications before they can be ... -
Biofiltration in Drinking Water Treatment: Reduction of Membrane Fouling and Biodegradation of Organic Trace Contaminants
(University of Waterloo, 2010-02-17)The goal of drinking water treatment is to produce and deliver safe water to the consumers. To achieve these objectives water treatment plants are designed based on the concept of the multibarrier approach which combines ... -
Biogeochemistry Across Spatiotemporal Scales: The Role of Reactive Interfaces in Modulating Landscape Scale Contaminant Fluxes
(University of Waterloo, 2022-09-09)The intensification of agricultural and urban activities has been accompanied by increased fluxes of nutrients to inland and coastal waters, leading to concerns of eutrophication and drinking water contamination. Certain ... -
Biologically Active Filtration Media Properties: Practical and Mechanistic Implications
(University of Waterloo, 2017-01-16)Biologically active filtration [BAF] can be used to concurrently remove particles and natural organic matter during drinking water treatment. The selection of a given media type for use in BAF can impact filter performance, ... -
Bond and Flexural Behaviour of Self Consolidating Concrete Beams Reinforced and Prestressed with FRP Bars
(University of Waterloo, 2013-04-29)Self consolidating concrete (SCC) is widely used in the construction industry. SCC is a high performance concrete with high workability and consistency allowing it to flow under its own weight without vibration and making ... -
Bond Behaviour of Beams Reinforced with Near Surface Mounted Carbon Fibre Reinforced Polymer Rods under Fatigue Loading
(University of Waterloo, 2011-04-19)Over the past decade, extensive research has been conducted on the strengthening of reinforced concrete (RC) structures using externally bonded fibre reinforced polymer (FRP). More recently, near-surface mounted (NSM) FRP ... -
Bond Behaviour of Concrete Beams with Glass Fibre Reinforced Polymer Bars Under Fatigue Loading

Bond Behaviour of Corroded and CFRP Repaired RC Beams Subjected to Monotonic and Repeated Loading
(University of Waterloo, 2012-09-27)All reinforced concrete (RC) design theories are based on the assumption that concrete exhibits a perfect bond with the steel reinforcement. The bond between steel and concrete is essential to the transfer of the load ... -
Bond of Corroded Reinforcement in Partial Depth Repairs in Reinforced Concrete Elements
(University of Waterloo, 2017-08-29)The bond in a reinforcement concrete (RC) structure is represented by the force transfer between the reinforcing bar and the surrounding concrete. All the RC structures are designed to have a perfect bond between the ... -
