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 ...
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 ...
Design, analysis and optimization of novel photo electrochemical hydrogen production systems
(2013-04-01)
Hydrogen is a green-energy carrier with a high heat of combustion. If obtained from renewable sources, it could be the ultimate and environmentally benign solution for the future energy requirements. This thesis presents ...
Design, analysis and experimental investigation of Cu-Cl based integrated systems
(2013-01-01)
Burning fossil fuels for power generation results in emissions of greenhouse gases such as carbon dioxide (CO2) and air pollutants such as nitrogen oxides (NOx) and sulfur oxides (SOx), which are harmful to living creatures ...
Investigation of energy storage options for sustainable energy systems.
(2013-08-01)
Determination of the possible energy storage options for a specific source of
energy requires a thorough analysis from the points of energy, exergy, and
exergoeconomics. The main objective of this thesis is to investigate ...
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 ...
Assessing district energy systems performance integrated with multiple thermal energy storages.
(2013-08-01)
The goal of this study is to examine various energy resources in district energy (DE) systems and then DE system performance development by means of multiple thermal energy storages (TES) application. This study sheds light ...
Thermal sustainability of low-temperature geothermal energy systems: System interactions and environmental impacts.
(2013-10-01)
In storing heat during summer for use in winter, the ground provides a better source/sink
of heat than the outside air in regards to heat pump efficiency, being cooler than the outside air in the summer and warmer in the ...
