Design optimization of aerodynamic drag at the rear of generic passenger cars using nurbs representation
(2013-05-01)
The rear geometry of a passenger car has the most significant influence on its aerodynamic characteristics. This thesis studied aerodynamic shape optimization of the rear geometry of passenger cars. The Non-uniform rational ...
Parallel design optimization of multi-trailer articulated heavy vehicles with active safety systems
(2013-04-01)
Multi-trailer articulated heavy vehicles (MTAHVs) exhibit unstable motion modes
at high speeds, including jack-knifing, trailer swing, and roll-over. These unstable
motion modes may lead to fatal accidents. On the other ...
Sum-rate maximization for active channels
(2013-04-01)
In conventional wireless channel models, there is no control on the gains of different
subchannels. In such channels, the transmitted signal undergoes attenuation and
phase shift and is subject to multi-path propagation ...
Development of an actuation system for a specialized fixture: providing two degrees of freedom for single point incremental forming
(2013-02-01)
In this thesis, an actuation system is developed for a Two-Axis Gyroscopic (TAG) adapter.
This adapter is a fixture with two auxiliary axes which is used for the Single Point
Incremental Forming (SPIF) technique to enhance ...
Simulation-based fault propagation analysis of process industry using process variable interaction analysis
(2013-01-01)
There are increasing safety concerns in chemical and petrochemical process industry. The huge explosion of Nowruz oil Field platform that happened in Persian gulf-IRAN at 1983, along with other disastrous events have ...
Experimental modelling of surface roughness and dynamic friction coefficient of diamond like carbon coated shafts
(2013-12-01)
Companies that coat their products with DLC often have strict surface roughness and friction coefficient goals. This research investigates the surface roughness and friction coefficient properties of uncoated and DLC coated ...
Investigation of energy storage options for thermal management in hybrid electric vehicles
(2013-01-01)
Electric and hybrid electric vehicles could have a significant role in the sustainable transportation. Higher power density lead to extra heat generation and thermal runaway in the Li-ion cells. Therefore, a successful ...
Modeling, analysis and optimization of integrated energy systems for multigeneration purposes
(2013-08-01)
Energy use is directly linked to well-being and prosperity across the world. Meeting the growing demand for energy in a safe and environmentally responsible manner is an important challenge. There are around seven billion ...
Intelligent fault diagnosis of gearboxes and its applications on wind turbines
(2013-02-01)
The development of condition monitoring and fault diagnosis systems for wind turbines has received considerable attention in recent years. With wind playing an increasing part in Canada’s electricity demand from renewable ...
Model based simulation of broaching operation: cutting mechanics, surface integrity, and process optimization
(2013-04-01)
Machining operations are widely used to produce parts with different shapes
and complicated profiles. As a machining operation, broaching is commonly used
for the machining of a broad range of complex internal and external ...
