Model predictive control of wheeled mobile robots
(2010-12-01)
The control of nonholonomic wheeled mobile robots (WMRs) has gained a lot of attention
in the field of robotics over the past few decades as WMRs provide an increased range of
motion resulting in a larger workspace. This ...
Motion planning for multi-link robots with artificial potential fields and modified simulated annealing
(2010-12-01)
In this thesis we present a hybrid control methodology using Artificial Potential Fields (APF) integrated with a modified Simulated Annealing (SA) optimization algorithm for motion planning of a multi-link robots team. The ...
Optimal power minimization in two-way relay network with imperfect channel state information
(2010-08-01)
We study a two-way amplify and forward relay network with two transceivers which
communicate through a network of nr relays while there is no direct link between the two
transceivers. Each relay is equipped with a single ...
Well-to-wheel greenhouse gas emissions and energy use analysis of hypothetical fleet of electrified vehicles in Canada and the U.S.
(2010-12-01)
The shift to strong hybrid and electrified vehicle architectures engenders controversy and brings about many unanswered questions. It is unclear whether developed markets will have the infrastructure in place to support ...
Risk-informed maintenance for non-coherent systems
(2010-12-01)
Probabilistic Safety Assessment (PSA) is a systematic and comprehensive methodology to evaluate risks associated with a complex engineered technological entity. The information provided by PSA has been increasingly implemented ...
A Hybrid LCC-VSC HVDC Transmission System Supplying a Passive Load
(2010-12-01)
High Voltage Direct Current (HVDC) transmission systems continue to be an excellent
asset in modern power systems, mainly for their ability to overcome the problems of AC
transmission, such as the interconnection of ...
The effect of high dose rate on tissue equivalent proportional counter measurements in mixed neutron-gamma fields
(2010-04-01)
Tissue equivalent proportional counters (TEPCs) are commonly used for radiation monitoring in areas where a mixture of neutron and photon radiations may be present, such as those commonly encountered in nuclear power plants. ...
Development and optimization of new generation start-up instrumentation systems (SUI) for domestic CANDU reactors
(2010-12-01)
Due to the age and operating experience of Bruce Power units, equipment ageing and obsolescence has become one of the main challenges that need to be resolved for all systems, structures and components in order to ensure ...
A generic methodology for the three dimensional display of radiation fields
(2010-04-01)
The radiation field visualization options available for engineers, scientists and health physicists have traditionally been based in the 2d realm, with techniques such as the generation of isodose curves. From the perspective ...
Thermodynamic performance assessment of three biomass-based hydrogen production systems
(2010-04-01)
Hydrogen is likely to be an important energy carrier in the future. It can be produced by the steam reforming of natural gas, coal gasification and water electrolysis among other processes. However current processes are ...
