Validation Methodologies for Construction Engineering and Management Research
(University of Waterloo, 2013-07-19)Validation of results is an important phase in the organization of a researcher’s work. Libraries and the internet offer a number of sources for guidance with respect to conducting validation in a variety of fields. However, ... -
Vapour Diffusion Control in Framed Wall Systems Insulated with Spray Polyurethane Foam
(University of Waterloo, 2009-04-30)The Intergovernmental Panel on Climate Change (IPCC) estimates that buildings account for 40% of the global energy use. The IPCC believes substantial improvements to building efficiency can be implemented easily by improving ... -
Vibration characterisation of aluminium pedestrian bridges
(University of Waterloo, 2014-08-29)Despite several full-scale applications in Canada, the vibrational characteristics and performance of aluminium pedestrian bridges have not been studied comprehensively in the literature. There is a large degree of variability ... -
Vibration Serviceability and Dynamic Modeling of Cold-Formed Steel Floor Systems
(University of Waterloo, 2008-09-10)The use of cold-formed steel as a framework for floor systems in multi-story buildings and single occupancy residences is becoming an increasingly popular alternative to traditional materials and techniques. Builders and ... -
Vibration Serviceability of Cold-Formed Steel Floor Systems
(University of Waterloo, 2017-01-18)Excessive vibration in response to human activities has been a significant problem associated with lightweight steel floor systems, especially cold-formed steel (CFS) floors. Methods for accurately predicting these vibrations ... -
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 ... -
Volume Changes during Fracture Injection of Biosolids
(University of Waterloo, 2007-05-22)The term biosolids refers to the nutrient-rich organic materials resulting from the treatment of domestic sewage at a wastewater treatment facility. It is a widely acceptable term for sewage sludge that has been treated ... -
Vulnerability measures for flood and drought and the application in hydrometric network design
(University of Waterloo, 2014-07-02)Climatic variability and change can have profound impacts on human societies and wildlife habitats. Extreme events and natural hazards such as floods, droughts, and windstorms, can lead to loss of lives, economic damages, ... -
Water Main Life Cycle Analysis Framework for the Economic Evaluation of OM&R (Operation, Maintenance and Renovation) Strategies.
(University of Waterloo, 2018-12-21)Municipal water systems deliver potable water to residents, businesses, and industries. The potable water infrastructure was mostly laid in 1880-1970`s in North America. Being a buried asset i.e. an out of sight network, ... -
A Web-based Transit Technology Selection Model
(University of Waterloo, 2013-04-22)There are many cities in North America planning to upgrade or implement public transportation infrastructure with the goals of increasing transit ridership and promoting transit-oriented development. The most commonly ... -
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 ... -
Wildfire Impacts on Water Quality and Treatability
(University of Waterloo, 2018-08-31)Forests are critical source areas for downstream drinking water supplies in many parts of the world. However, large-scale landscape disturbance by insect infestation and wildfire—exacerbated by warming climate—can have a ... -
Winter Road Surface Condition Estimation and Forecasting
(University of Waterloo, 2013-06-13)This thesis research has attempted to address two challenging problems in winter road maintenance, namely road surface condition (RSC) estimation and forecasting. For RSC estimation, the goal of the research was to develop ... -
Work Zone Safety Assessment and Throughput Analysis for High Volume Highways Using Random Parameter Models
(University of Waterloo, 2019-12-12)Highways and freeways could be considered the most important transportation infrastructure in North America; these vital routes are necessary for the efficient haulage of huge amounts of goods and services. Several factors ...
