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...

Design, Simulation and Evaluation of Effective Industrial Information Systems: Case of Machine Condition Monitoring and Maintenance Management Information Systems
DownloadFall 2013
Industrial information systems can improve the management of industrial operations by providing relevant and timely information on the status of physical assets via condition and process monitoring systems, and by enabling the effective use of data by systems and processes that restore proper...

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 2013
The increasing level of system complexity in the current competitive market implies that efficient asset management is of paramount importance, particularly for systems with costly downtime and failure. Timely detection of faults and failures through an efficient reliability and health management...

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...

Most current models for the deposition of aerosol particles in the human lung are based on a Lagrangian reference frame, which is ill-suited for modeling transient eects. Deposition models based on an Eulerian reference frame are much better at capturing instantaneous time-dependent eects, though...
