(University of Waterloo, 2008-08-11)There is shift in the Architectural / Engineering / Construction and Facility Management (AEC&FM) industry toward performance-driven projects. Assuring good performance requires efficient and reliable performance control ... -
Automatic feature selection and weighting for the formation of homogeneous groups for regional IDF estimation
(Elsevier, 2019-08)The intensity-duration frequency (IDF) curve has been used as an effective tool to quantify the risk associated with the impact of extreme rainfall on civil infrastructure. However, recent changes in the rainfall climatology ... -
An Automatic Image Recognition System for Winter Road Condition Monitoring
(University of Waterloo, 2011-02-22)Municipalities and contractors in Canada and other parts of the world rely on road surface condition information during and after a snow storm to optimize maintenance operations and planning. With an ever increasing ... -
Automatic Transit Schedule Updating Using AVL/APC System
(University of Waterloo, 2018-09-11)Observing and fixing transit vehicle’s schedule adherence problems have always been one of the main priorities of a transit agency, and different approaches have been developed over time to help reflect transit vehicle’s ... -
Automatically Assessing the Need for Traffic Signal Retiming Using Connected Vehicle Data
(University of Waterloo, 2023-11-27)Traffic signal controllers are a critical element in managing urban traffic systems effectively. The emergence of Automated Traffic Signal Performance Measures (ATSPM), aided by recent technological advancements, allows ... -
Automating and Optimizing a Transportation Mode Classification Model for use on Smartphone Data
(University of Waterloo, 2015-04-01)As transportation engineering and planning evolve from “data poor” to “data rich” practices, methods to automate the collection and translation of data to information become increasingly important. Advances in wireless ... -
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 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
