Investigation of the impact of impurities on the properties of nitride semiconductors grown by RPECVD
(2015-10-21)
Progress toward the improvement of optical emission from InGaN optical active region devices is made through a combination of the tailoring of p-type gallium nitride growth recipes and bandstructure calculations on a graded ...
Nutrients Recovery from Municipal Wastewater Effluent using Electrochemical and Freeze Concentration Approaches
(2016)
Municipal wastewater (MWW) is now being re-evaluated as a potential multi-resource for water,
energy and nutrients. Anaerobic membrane bioreactors (AnMBRs) are increasingly being investigated
as a cost-effective biological ...
Online loss minimization based direct torque and flux control of IPMSM drive
(2015-10-21)
With the advent of high energy rare earth magnetic material such as, third generation neodymium-iron-boron (NdFeB), permanent magnet synchronous motor (PMSM) is becoming more and more popular in high power industrial ...
Analysis of improvement for turn on/off performance of the MOSFET gate drive waveform
(2012-11-10)
This thesis shows that the gate waveform of a power MOSFET driven by a specialized driver chip used in industry is imperfect and induces increased power loss in the MOSFET and lowers overall efficiency. The accurate ...
Real-time implementation of some bilateral teleoperation schemes
(2012-11-10)
Today's technology has pushed back many boundaries that we thought were impossible. One of these technologies is bilateral teleoperation. Bilateral teleoperation allows an operator to control a robot, at a distance, over ...
Intelligent sliding mode control in flexible structures
(2012-11-10)
The first objective of this work is to develop an intelligent sliding mode controller for vibration control in flexible structures. The proposed control consists of two processes: system identification and sliding mode ...
Experimental Investigation and Modelling of Sand Jets Passing through an Immiscible Layer
(2016)
Sand jets passing through two immiscible liquids, water and oil have many applications in the field of civil and environmental engineering such as tailings transport, dredging and discharge of industrial and urban wastewater. ...
Piezoelectric Energy Harvesting with a Nonlinear Energy Sink
(2016)
Energy transfer from one system to another system, or vice versa, is happening constantly in many
processes with various forms. Vibration in machines or structures can be considered as a form of
energy transfer from a ...
Technical feasibility and economical viability of remote hybrid power systems in Northern Ontario
(2011)
As of 1996 there were 302 remote communities with a total population of 205,041 in
Canada. These communities are not connected to the Bulk Electric System (BES)
and as such are responsible for maintaining their own power ...
Nonlinear adaptive control for robust wide speed range operation of IPMSM drives
(2015)
Various applications, including robotics, spindle drives, machine tools, etc. rely on accurate, reliable controllers to deliver the required drive performance. With recent advances in magnetic materials and semiconductor ...
