Characterization of Particulate Matter Morphology and Volatility for Two Direct-Injection Engines
DownloadFall 2015
Particulate matter emitted from two direct injection engines has been characterized by morphology, volatility, mass-mobility exponent, effective density, and size distribution using tandem measurements from a centrifugal particle mass analyzer (CPMA) and differential mobility analyzers (DMA). The...

Development and Applications of an Emissions Micro-Simulation Tool for Transportation Infrastructure Design
DownloadFall 2014
Transportation emissions constitute a significant portion of overall emissions inventories, and contribute to air quality health concerns. Reductions in transportation emissions can be achieved through efficient design of infrastructure, effective policy and regulation, and informed planning...

Development of Empirical Models to Predict Deposition of Aerosols in the Extrathoracic Airways of Children
DownloadSpring 2012
The experimental studies described in this thesis were performed with the goal of measuring deposition of aerosols, inhaled either nasally or orally, in the extrathoracic airways of children in different age groups. We pursued in vitro methods and characterized the deposition of aerosols in the...

Fall 2021
With continued growth in global carbon emissions, much of the developed world is curtailing its dependence on fossil fuels. Broad decarbonization will not come from a single source, but rather a combination of policy, technology, and innovation. Wind power has seen significant development in...

Spring 2014
The main goal of this research was to investigate the application of the ISO 14001 standard in Canadian organizations. Seventeen research questions were defined and addressed using a survey of 32 organizations registered to the standard. Descriptive, explorative factor, reliability and cluster...

Improving Measurements of the Mixing State and Mass Concentration of Particulate Emissions from Aircraft Engines
DownloadSpring 2016
This research is focused towards improving techniques used to measure particulate emissions from aircraft engines, on two fronts: first, to characterize and quantify the mixing state of particulate emissions; and second, to calibrate black carbon mass instruments with a traceable mass...

Spring 2018
The centrifugal particle mass analyzer (CPMA)-electrometer system has been proposed as an alternative method of calibration for devices that measure black carbon. This system is proposed to replace the current calibration standard of NIOSH 5040. The repeatability and intermediate precision of the...

Study of Enhanced Deposition due to Magnetic Field Alignment of Ellipsoid Particles Using Direct Numerical Simulations
DownloadFall 2012
A recent in vitro study demonstrated a non invasive method to enhance local deposition in a small airway by controlling the angular position of magnetic high aspect ratio particles. This technique could mitigate the challenge of providing sufficient therapeutic effects when using aerosolized...

Techno-economic feasibility of hybrid energy systems for small-scale space heating applications in Canada
DownloadSpring 2021
Given the large energy consumption for space heating demands in Canada, renewable energy heating systems are becoming increasingly more popular and more important for small scale applications. However, these face tough challenges for applicability in cold climate regions due to various physical...
