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 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 ...
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 ...
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 and implementation of a single phase modified Z-source inverter topology for photovoltaic/grid interconnected DC charging applications
(2018-03-01)
Solar energy has been the most popular sources of renewable energy for residential and
semi-commercial applications. Solar energy sources alone cannot be used to charge an
electric vehicle (EV). Solar/Grid interconnected ...
Design and development of a universal gripper mechanism and development of an omni-directional unmanned aerial vehicle for autonomous perching
(2020-04-01)
A novel omni-directional multi-rotor prototype with an attached gripper mechanism named the OmniRaptor is presented with the capability of landing on inclined members in a controlled, stable manner to perform construction ...
Analysis, development, and control of multi-degree-of-freedom passive haptic devices
(2020-08-01)
Stability and transparency are key design requirements in haptic devices. Replacing conventional electric motors with passive actuators such as brakes or dampers can improve both stability and transparency as passive ...
Investigation of three integrated energy systems with desalination, heat storage, thermochemical cycles and heat upgrade
(2020-09-01)
This thesis study proposes three different novel renewable energy-based multigeneration integrated systems with molten salt heat storage and desalination options where copper-chlorine (Cu-Cl) and magnesium-chlorine (Mg-Cl) ...
