Learning-based Image Scale Estimation for Quantitative Visual Inspection of Civil Structures
(University of Waterloo, 2021-02-25)The number of assets of civil infrastructure (e.g., bridges or roads) have been increasing to meet the demands of growing populations around the world. However, they degrade over time due to environmental factors and must ... -
Leveraging Deep Learning and Advanced Statistical Methods for Investigating the Fate and Transport of Microplastics in a Waste Water Treatment Plant
(University of Waterloo, 2023-07-26)Microplastics (MPs), defined as plastic particulates smaller than 5mm, pose significant environmental concerns due to their widespread distribution, adverse ecological impacts, and potential human health implications. The ... -
Life cycle sustainability assessment of asset management plans for municipal wastewater systems
(University of Waterloo, 2019-01-24)Municipal governments have the responsibility to provide safe drinking water and handle polluted water to protect their citizen’s health and safety. Maintaining water infrastructure systems, including wastewater collection ... -
The Life-Cycle Assessment of a Single-Storey Retail Building in Canada
(University of Waterloo, 2010-08-26)In North America, the operation of buildings accounts for approximately one third of the total energy use and greenhouse gas emissions annually. Office buildings are responsible for roughly 35% of the total commercial/in ... -
Lightweight Cellular Concrete as Flexible Pavement Subbase Material: Field Performance and Sustainability Study
(University of Waterloo, 2022-12-01)Enhancing the long-term performance of road infrastructure is an important goal for engineers in Canada, especially with changing climatic conditions. This has brought about varying approaches in design and construction ... -
Lightweight Cellular Concrete: Applicability of Pavement Subbase Layer Materials
(University of Waterloo, 2021-12-06)Canada is the second-largest country in the world and has over 1.04 million km of roads. Residents and industries rely on the road network as it contributes significantly to quality of life. Pavement structures built over ... -
LOAD PREDICTION FOR A MOORED CONICAL DRILLSHIP IN LEVEL UNBROKEN ICE: A DISCRETE ELEMENT AND EXPERIMENTAL INVESTIGATION
(University of Waterloo, 2009-12-22)This thesis is composed of theoretical, experimental, and numerical studies. In Part I, it discusses fundamental challenges of the discrete element method, provides a set of algorithms for addressing them, and presents ... -
Local Calibration of AASHTOWare® Using Ontario Pavement Management System Data PMS2
(University of Waterloo, 2015-04-23)Well designed built and maintained pavements will sustain the safe and comfortable transportation of people and goods. Effective monitoring requires information about evolving pavement condition, including details about ... -
Long Term Two-Phase Flow Analysis of the Deep Low Permeability Rock at the Bruce DGR Site
(University of Waterloo, 2011-04-27)Abnormal pressures have been measured in the deep boreholes at the Bruce site, southern Ontario, where a deep geologic repository for low and intermediate level radioactive waste disposal has been proposed. The pressure ... -
Long-term behaviour of GFRP prestressed concrete beams
(University of Waterloo, 2015-11-12)During the last two decades, fibre-reinforced polymer (FRP) composites have emerged as prom-ising materials that can be used in lieu of steel for reinforcing concrete structures due to their corrosion-resistant properties, ... -
Machine-Learning Framework for Efficient Multi-Asset Rehabilitation Planning
(University of Waterloo, 2021-10-25)While smart cities are viewed as the way of the future, the infrastructure assets expected to support the different smart services are currently managed using frameworks that are outdated, subjective, and inefficient. Such ... -
