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 Modeling of Pitting Corrosion in Steam Generators
(University of Waterloo, 2007-09-05)Steam generators in nuclear power plants experienced varying degrees of under-deposit pitting corrosion. A probabilistic model to accurately predict pitting corrosion is necessary for effective life-cycle management of ... -
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 PVC Encased Reinforced Concrete Walls under Eccentric Axial Loading
(University of Waterloo, 2014-01-23)Stay-in-place (SIP) formwork has been used as an alternative to the conventional formwork system. The systems are mainly assembled on site, hence simplifying the construction process and reducing the construction time as ... -
Behaviour of Shear Critical RC Beams with Corroded Longitudinal Steel Reinforcement
(University of Waterloo, 2010-09-29)This thesis discusses the results of an experimental program designed to investigate the effect of corrosion on the behaviour of shear critical reinforced concrete (RC) beams. The results of twenty RC beams (ten deep beams ... -
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 ... -
Behavioural Economics: Application to Quotidian Construction Decisions
(University of Waterloo, 2015-07-20)Working on a construction project requires making important decisions quickly and frequently. Most of these decisions are made under risk in that the outcomes are not known, but their probabilities and impacts can be ... -
A Bench-scale Evaluation of the Removal of Selected Pharmaceuticals and Personal Care Products by UV and UV/H₂O₂ in Drinking Water Treatment
(University of Waterloo, 2006-12-22)A bench-scale study of the degradation of four selected pharmaceuticals and personal care products (PPCPs) was carried out using UV and UV/H₂O₂ treatment employing low pressure (LP) and medium pressure (MP) lamps. The ... -
Benchmarking the Sustainability of Sludge Handling Systems in Small Wastewater Treatment Plants in Ontario
(University of Waterloo, 2018-08-20)This project quantitatively benchmarked all aspects of sludge handling in a cross-section of small wastewater treatment plants across Ontario. Using plant operational data and on-site measurements, a variety of sustainability ... -
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 ... -
Biofilm Dynamics in Drinking Water Biofiltration & Downstream Nanofiltration Biofouling
(University of Waterloo, 2018-05-17)Natural organic matter (NOM) is a concern in many surface waters and must be removed by water treatment processes for cost-effective production of safe and aesthetically pleasing drinking water. Biological filtration is ... -
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 ... -
Biofiltration-based “green technology” as a techno-ecological nature-based solution for drinking water treatment and climate change resilience
(University of Waterloo, 2022-06-02)While drinking water treatment process design is based on current and anticipated source water quality, changing climate makes it increasingly difficult to anticipate drinking water source quality and treatability. Although ... -
Biogeochemical Hotspots: Role of Small Water Bodies in Landscape Nutrient Processing
(University of Waterloo, 2017-05-09)Increased loading of nitrogen and phosphorus from agricultural and urban intensification has led to severe degradation of inland and coastal waters. Lakes, reservoirs, wetlands, and streams retain and transform these ... -
