Analysis and optimization of fuel cell based integrated powering systems for clean rail applications
(2019-08-01)
In this thesis, proposals of novel integrated fuel cell powering systems for cleaner railway applications are presented and analyzed thermodynamically. Both energy and exergy analyses are conducted on these systems for ...
Experimental investigation and analysis of a new light-based hydrogen production system
(2014-12-01)
Due to the world’s increasing population and the rising standard of living, global energy demand is expected to keep increasing. The limited nature of fossil fuels and their non-homogenous global distribution along with ...
Flow-sound interaction mechanism of a single spirally finned cylinder in cross-flow
(2017-01-01)
Over the years, some effort has been expended in the improvement of heat transfer performance in tubular heat exchangers. This can be achieved by adding different types of fins to the outer tube surface, effectively ...
Customized topology optimization for additive manufacturing
(2019-08-01)
One of the biggest limitations of additive manufacturing (AM) is the resulting production times. Due to the layer-based method of material deposition, the time to produce a single part is substantial compared to techniques ...
Design and development of hydrophobic and protective polymer-based spray coatings for treating glass surfaces in building and automotive applications
(2019-08-01)
Glass surfaces in buildings and vehicles are susceptible to two common problems: unrestricted energy transmittance of light-waves resulting in increased HVAC costs, and reduced visibility as a consequence of wetting during ...
Active transport and concentration of analytes in microfluidic paper based analytical devices using ion concentration polarization
(2019-04-01)
Microfluidic paper-based analytical devices (µPADs) have a high potential for miniaturizing complex testing functions, since they are inexpensive, disposable, and portable. Paper has the advantage over traditional fluid ...
Time-efficient offloading and execution of machine learning tasks between embedded systems and fog nodes
(2019-12-01)
As embedded systems become more prominent in society, it is important that the technologies that run on them must be used efficiently. One such technology is the Neural Network (NN). NN's, combined with the Internet of ...
Development and investigation of compressed air only and hybrid powering options
(2016-04-01)
Currently, significant resources are deployed to investigate electric and pneumatic vehicles in response to environmental, energy and consumer pressures. The goal of this thesis is to show conceptual development, analyze, ...
Development of FEA wide-base truck tire and soil interaction models
(2016-07-01)
Tires are considered one of the most important components of ground vehicles as they are the only link between the chassis and ground. They support the vehicle weight and cushion road surface irregularities to provide a ...
Fault tolerant control of active trailer steering systems for multi-trailer articulated heavy vehicles
(2017-07-01)
Faults in a controlled plant often deteriorate the system performance. In severe cases, faults pose a risk of component damage, plant shutdown or even personnel safety. Fault Tolerant Control (FTC) aims at preventing the ...
