Video Imaging Methodology for Estimation of Pile Capacity
(University of Waterloo, 2018-05-17)Piles have been used for generations in areas with weak soil conditions to reinforce existing ground or to support bridges and structures. As the piling industry increased over these years it was necessary to develop ... -
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 ... -
Comprehensive CP Optimization for Dynamic Scheduling in Construction
(University of Waterloo, 2018-05-11)Delays and cost overruns are common facts in construction projects due to its increasing complexity, the day-to-day dynamic changes, the stricter execution constraints, and the general lack of efficient scheduling tools ... -
Investigation of Visualization Needs for Vertical Repetitive Projects
(University of Waterloo, 2018-04-27)Repetitive construction projects, particularly high-rise buildings, are complex projects that suffer from cost overruns and delays. For these projects, efficient repetitive scheduling becomes necessary. Repetitive scheduling, ... -
Wildfire and Forest Harvesting Effects on Natural Organic Matter: Implications to Drinking Water Treatability
(University of Waterloo, 2018-04-19)Forested catchments are critical for water supply globally and provide ~60% of the water supplies for the world’s 100 largest cities and 2/3 of all water supplies, including drinking water for ~180 million people in the ... -
Numerical Analysis of Debonding Mechanisms of Externally Bonded FRP Reinforcement in RC Beams
(University of Waterloo, 2018-04-16)There is an urgent need to develop economic and efficient methods to repair and strengthen existing reinforced concrete structures. This demand is motivated by several factors including the aging of concrete structures, ... -
A novel selective disassembly sequence planning method for adaptive reuse of buildings
(Elsevier, 2018-05-10)Adaptive reuse of buildings can be an attractive alternative to new construction in terms of sustainability and a circular economy. Achieving net benefits with adaptive reuse partly relies on efficiently planning building ... -
Quantifying the Impact of Transit Rider Perception and Satisfaction on User Cost: An Experiential Sampling Approach Using Smartphones
(University of Waterloo, 2018-03-15)The aim of travel demand modelling is to accurately estimate trips in future time periods by understanding current travel behaviours. Accurate generalized cost modelling for determining transit mode share has proven elusive. ... -
Advanced Traffic Signal Control Using Bluetooth Detectors
(University of Waterloo, 2018-03-14)Traditionally signal timing plans are developed for expected traffic demands at an intersection. This approach generally offers the best operation for typical conditions. However, when variation in the traffic demand occurs, ... -
Novelty Detection in Airport Baggage Conveyor Gear-Motors Using Synchro-Squeezing Transform and Self-Organizing Maps
(Prognostic and Health Management Society, 2013)A powerful continuous wavelet transform based signal processing tool named Synchro-squeezing transform (SST) has recently emerged in the context of non-stationary signal processing. Founded upon the premise of time-frequency ... -
Gearbox Fault Detection using Synchro-squeezing Transform
(Elsevier, 2016)This paper presents a novel fault-detection method for gearbox vibration signatures using synchro-squeezing transform (SST). Premised upon the concept of time-frequency (TF) reassignment, SST provides a sharp representation ... -
DEMAND MODEL FOR CRUDE OIL RAIL AND PIPELINE SHIPMENTS IN CANADA
(University of Waterloo, 2018-01-24)Global energy demand is expected to increase significantly over the next 10-20 years, and in the absence of an increase in pipeline capacity, Canadian crude oil shipments are likely to be diverted to rail. The current rail ... -
Fatigue Behaviour of Aluminum Friction Stir Welds Under Highway Bridge Conditions
(University of Waterloo, 2018-01-22)Friction stir welding (FSW) is a solid state joining process performed by rotating a cylindrical tool with a short protrusion between the two metal pieces to be joined. The combination of frictional and deformation heating ... -
Evaluating Unbonded Concrete Overlay for Usage on Ontario Residential Streets
(University of Waterloo, 2018-01-22)Composite pavements have become increasingly common in North America, these pavements usually result from the rehabilitation of Portland cement concrete (PCC) pavements. When a PCC pavement reaches close to the end of its ... -
Compressed Air Energy Storage in Salt Caverns: Geomechanical Design Workflow, CAES Siting Study from a Geomechanics Perspective, and Deep Brine Disposal
(University of Waterloo, 2018-01-22)As agreed in the Paris Agreement, Canada is committed to combat climate change through reducing greenhouse gas (GHG) emissions and keeping the temperature rise well below 2° C above pre-industrial levels. One of the ways ... -
The Static and Fatigue Behaviour of Through-Bolt Shear Connectors in Steel-Precast Composite Bridge Girders
(University of Waterloo, 2018-01-22)Increasing demand for the rapid and economically efficient construction of bridges has encouraged engineers to employ the use of accelerated bridge construction through modular assembly. The replacement of vehicular bridges ... -
Nitrogen Dynamics in a Harvested Rocky Mountain Catchment
(University of Waterloo, 2018-01-19)While the impacts of forest harvesting on nitrogen (N) are largely well documented, changes to watershed N following harvesting are difficult to characterize within steep, mountainous terrain creating uncertainty for ... -
Testing of Innovative Pipe Renewal Liners for Renovation of Potable Water Distribution Pipelines
(University of Waterloo, 2017-12-19)Trenchless renovation has been in operation since the 1970’s in North America and the United Kingdom. However, it has not been widely accepted due to cost effectiveness concerns. Many Canadian cities are faced with the ... -
Application of Crowdsourced Travel Data in Identifying Potential Opportunities for Transportation Demand Management
(University of Waterloo, 2017-12-19)Traffic congestion is a major concern that many urban regions contend with. Since the 1970s, transport practitioners have sought out different ways to alleviate the negative impacts of congestion. The concept of Transportation ... -
Investigation of the Impact of Mixing Intensity on Dissolved Oxygen Half Velocity Constants in a Sidestream Deammonification Environment
(University of Waterloo, 2017-12-18)The liquid waste (centrate) from the dewatering stage in the solids treatment stream (sidestream) of a wastewater treatment plant is typically rich in ammonium. If this centrate is recycled to the wastewater treatment ...
