This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.
Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

Characterization and Control of Cyclic Variability in a Gasoline/Natural Gas Dual-Injection Spark Ignition Engine
DownloadSpring 2016
Reducing the cyclic variability of a gasoline/natural gas dual injection spark ignition engine using minimum variance control is the subject of this thesis. Cylinder pressure is used to calculate four combustion metrics, the standard deviation of which is used as an indicator of cyclic...

Effects of Negative Valve Overlap on HCCI Combustion and its use in the Control of HCCI Combustion Timing
DownloadFall 2014
Homogeneous charge compression ignition (HCCI) combustion can produce higher efficiencies and lower emissions when compared to tradition spark or compression ignition engines. This study reports an experimental investigation into the effects of valve timings on HCCI combustion conditions. Using a...

Spring 2016
A dual-fuel system is used to control HCCI combustion timing and load in a CFR engine. The systems steady-state response to iso-octane and n-heptane injected energy is investigated then a dynamic ARMAX model is found using system identification. This model is used to design a norm-optimal...
