Nonlinear dynamics of railway wheelsets incorporating randomness
(2007)The thesis is to investigate the dynamic behavior of a single-axle railway wheelset and identify its chaotic behavior by means of time history, phase portrait, Lyapunov exponents, information dimension, bifurcation diagram ... -
Development and implementation of various speed controllers for wide speed range operation of IPMSM drive / by Md Muminul Islam Chy.
(2007)Despite many advantageous features of interior permanent magnet synchronous motor (IPMSM), the precise speed control of an IPMSM drive becomes a complex issue due to nonlinear coupling among its winding currents and the ... -
Recent Chinese immigrants' perceptions of English language and culture learning in Canada

Investigation of the Au-induced morphology of 3.8 and 12.3 degree silicon surfaces / by Wei Wu.
(2007)We have used a combination of scanning tunneling microscopy (STM) and low energy electron diffraction to investigate the Au-induced morphology of vicinal Si samples miscut from (111) by 3.8°, and 12.3° toward [112]. The ... -
Self-tuned neuro-fuzzy controller based induction motor drive / by Zhi Rui Huang.
(2007)Among various ac motors, induction motor (IM) occupies almost 90% of the industrial drives due to its simple, robust construction and generally satisfactory efficiency as compared to dc motor. However, the control of IM ... -
Predictive value of visual attention mechanisms for driving ability / by Marie J. Parkkari.
(2007)The increasing population of older adults and their greater risk of involvement in collisions has prompted research into various aspects of driving behaviour. Tests of visual attention have shown promise for predicting ... -
Chinese students' later-year experiences in Canadian universities / by Shimei Zang.

Stand structure differences resulting from post-harvest silviculture in boreal mixedwoods
(2007)Under the Ontario Forest Accord, several parcels of land have recently been designated as protected areas reducing the area available for forest management. As a result, forestry companies will likely have to intensify ... -
Non-collocated control of vibration of a three-DOF structure using the electromagnetic vibration absorber
(2007)Vibration control is very important in many areas including machine operation and daily life. Semi-active vibration control integrates a tuning control scheme with a tunable vibration absorber for suppression of vibration ... -
Transport of Escherichia coli through soil / by Bruce Rosa.
(2007)Sorption is an important process in the retention of pathogens by clay barriers. Batch sorption experiments were conducted to investigate the sorption of nonpathogenic 'E. coli' to illite, kaolinite, and montmorillonite ... -
On-line estimation of first order plus dead time process parameters based on under or over-parameterized models
(2007)Simple on-line process identification methods that can be used in tuning PID controllers or any other controllers have been studied in this work. The underlying continuous-time first order plus dead time FOPDT process model ... -
