Improving Predictive Models for Road Safety Screening: Cost-Benefit Data Analytics and Deep Generative Models
(University of Waterloo, 2023-04-17)The process of identifying the sites (e.g., road segments, intersections) within a road network that are most in need of detailed safety audits and interventions with the most potential for improvement is known as road ... -
Improving the Fiscal Transparency and Sustainability of Public-Sector Transportation Infrastructure
(University of Waterloo, 2017-08-25)Public-sector infrastructure funding is a complex and often unclear process. Cities operate most efficiently if there is an adequately-funded transportation network with which residents and visitors can easily travel from ... -
Improving the Understanding of Factors Influencing Cryptosporidium Removals Reported for Granular Media Filtration
(University of Waterloo, 2016-01-13)Cryptosporidium is an important waterborne protozoan pathogen which has been implicated in several large gastrointestinal disease outbreaks attributable to inadequate treatment of drinking water. Unfortunately, Cryptosporidium ... -
In-situ chemical oxidation of chlorendic acid by persulfate: Elucidation of the roles of adsorption and oxidation on chlorendic acid removal
(Elsevier, 2019-10-15)The oxidation of chlorendic acid (CA), a polychlorinated recalcitrant contaminant, by heat-, mineral-, and base-activated persulfate was investigated. In pH 3–12 homogeneous (i.e., solid-free) solutions, CA was oxidized ... -
Incorporating Pavement Sustainability into Municiple Best Practices
(University of Waterloo, 2012-09-04)Maintaining a functioning road network is a challenge in today’s society due to the financial restrictions faced by all levels of government. A means of determining how to efficiently spend their limited funding must be ... -
Incorporating Environmental Sustainability into Pavement Design and Management
(University of Waterloo, 2022-01-12)Increasing interest in pavement sustainability has led to the development of sustainability assessment tools and a plethora of potential indicators. Well-designed indicators are capable of quantitatively tracking and ... -
Incorporating GHG Mitigation into Ontario Highway Pavement Engineering Practices
(University of Waterloo, 2019-08-23)Greenhouse Gas (GHG) emissions are main concern for many national and international agencies. Increased human activities and growth in all sectors are affecting our society in a positive way but also putting our future ... -
Industry Foundation Processes (IFP): Theoretical and Practical Foundations for the Construction Industry
(University of Waterloo, 2017-01-12)Industry foundation processes are formulated to improve capital project process conformance and interoperability. These processes are used to implement key elements of practices. Several research studies confirm that the ... -
Inertial, Transient, and Turbulent Flow through Deformable and Propagating Fractures: Theory and Computational Engineering
(University of Waterloo, 2023-07-20)Fluid flow in deformable fractures is important to many natural and industrial geological engineering applications including contaminant transport, geothermal energy, and hydraulic stimulation. Large-scale simulations of ... -
Inferring 3D Cellular Forces from Confocal Image Stacks
(University of Waterloo, 2015-06-15)If we are to understand why cells move in contexts such as early embryo development, wound healing, cancer metastasis and construction of engineered organs, and if we are to learn how to better influence their associated ... -
Influence of Construction Details on the Vibration Performance of Cold-Formed Steel Floor Systems
(University of Waterloo, 2008-05-23)Vibrations associated with lightweight floor systems, as a serviceability criterion, are not well addressed in current residential construction practice. Cold-formed steel floor systems are usually lighter and have less ... -
The Influence of Jointed Fabric and Stress Ratio on Deformation and Fluid Flow
(University of Waterloo, 2017-01-24)There are remarkable volumes of hydrocarbon resources in low-permeability naturally fractured rock masses (NFRs) characterized by naturally occurring discontinuities. Natural fractures are one of the most important factors ... -
Influence of Soil Parameters on Local Pier Scour Depth
(University of Waterloo, 2021-12-15)Bridge scour is a phenomenon where erosion of the sediment bed surrounding bridge foundation occurs due to fluid forces arising from currents, waves, and turbulence. Scour around foundation components such as piers, piles ... -
Informing the practice of ground heat exchanger design through numerical simulations
(University of Waterloo, 2013-02-22)Closed-loop ground source heat pumps (GSHPs) are used to transfer thermal energy between the subsurface and conditioned spaces for heating and cooling applications. A basic GSHP is composed of a ground heat exchanger (GHX), ... -
Infrastructure Asset Management Readiness Assessment of Ontario Municipal Water Utilities
(University of Waterloo, 2020-02-26)The safety and quality of services provided by municipal water utilities depend on sound water and wastewater infrastructure. Nevertheless, according to the 2016 Canadian Infrastructure Report Card, about 12% of this ... -
Initial Biodegradation Potential of Microcystin-LR by Biofilters Experiencing Sudden Cyanobacterial Blooms in Drinking Water Treatment
(University of Waterloo, 2018-09-20)Cyanobacterial blooms have become a major cause of drinking water problems because certain metabolites from cyanobacteria are toxic to human health. Microcystin-LR (MC-LR) is one of the most commonly detected cyanotoxins. ... -
