Development and analysis of a high temperature electrolyser for the Cu-Cl cycle for hydrogen production
(2017-01-01)
A number of thermochemical cycles have been investigated to produce hydrogen from water. However, most of these cycles operate at over 800°C. The relatively lower temperature (550°C) requirement and use of inexpensive ...
Flow-sound interaction mechanism of a single finned cylinder in cross-flow
(2017-04-01)
The flow-sound interaction mechanism of a single finned cylinder in cross-flow is experimentally investigated and compared to that resulting from an equivalent bare cylinder. The flow field changes that result from the ...
Sparse signal representation based algorithms with application to ultrasonic array imaging
(2016-06-01)
We address one- and two-layer ultrasonic array imaging. We use an array of transducers to inspect the internal structure of a given specimen. In the case of one-layer imaging we also address the problem of mode conversion. ...
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 ...
Investigation of new phase change material based thermal management systems for Li-ion batteries
(2017-01-01)
In this thesis, a battery pack consisting of three A123 20Ah cells connected in series is tested with various cooling methods at different discharge rates. Four different coolant inlet temperatures are selected for the ...
Conceptual development and analysis of sustainable powering options for hybrid vehicles
(2018-02-01)
Hydrogen and ammonia are the carbon-free fuels that have the potential to replace the fossil fuels in the near future. In addition, they can also act as energy carriers and storage media for many applications; particularly ...
Access control obligation specification and enforcement using behavior pattern language
(2018-01-01)
Increasing the use of Internet-based devices offers novel opportunities for users
to access and share resources anywhere and anytime so that such a collaborative
environment complicates the design of an accountable ...
Development and investigation of integrated solar systems for hydrogen and methanol production
(2018-04-01)
Implications of climate change, in particular the negative effects of greenhouse gas (GHG) emissions resulting from fossil fuel combustion, as well as the finite nature of fossil fuels necessitate the implementation of ...
Automated wavelet-based fault detection and diagnosis for smart distribution systems and microgrids
(2017-08-01)
The legacy electric power system is defined as a one-way power flow from a centralized
power generation plant to customers (consumers). In the smart distribution systems, the customers
are allowed to produce electricity ...
Wireless transmission with energy harvesting and storage
(2017-01-01)
In this dissertation, online power control strategies are proposed for wireless communication
systems equipped with energy harvesting devices and finite-capacity batteries. The
methods are proposed for the unbounded ...
