Near Sets in Set Pattern Classification
(2015-02-06)
This research is focused on the extraction of visual set patterns in digital images, using relational properties like nearness and similarity measures, as well as descriptive properties such as texture, colour and image ...
Vibrational Energy Harvesting with Piezoelectric Cantilevers
(2014-09-02)
Due to decreasing power requirements for wireless networks and other microwatt devices, energy harvesting from ambient vibrations has become a realized power source. Piezoelectric cantilevers are a viable option as the ...
Energy-efficient strategies with base station power management for green wireless networks
(IEEE PublishingCambridge University Press, 2013-08)
In this thesis, our objective is to improve the energy efficiency and load balance for wireless networks. We first study the relationships between the base station (BS) on/off operation and traffic distribution. A cooperative ...
Implementation of an IEC 61850 Sampled Values Based Line Protection IED with a New Transients-Based Hybrid Protection Algorithm
(2016)
Over the course of the last decade, IEC 61850 has become the leading standard for electrical substation automation the world over. This thesis presents the work done towards implementing an IEC 61850 sampled values based ...
Dielectrophoresis study of electroporation effects on dielectric properties of biological cells
(American Institute of Physics, 2016-01)
Electroporation affects the dielectric properties of cells. Dielectric measurement techniques can provide a label-free and non-invasive modality to study this phenomenon. In this thesis we introduce a dielectrophoresis ...
A computationally intelligent approach to the detection of wormhole attacks in wireless sensor networks
(World Comp,14th International Conference on Wireless Networks, 2015World Comp,15th International Conference on Wireless Networks, 2016World Comp, International Conference on Security and Management, 2016, 2015-07-29)
This thesis proposes an innovative wormhole detection scheme to detect wormhole attacks using computational intelligence and an artificial neural network (ANN). The aim of the proposed research is to develop a detection ...
Adaptive Phase Locked Loops for VSC connected to weak ac systems
(2015-04-13)
The performance of the High voltage dc systems is dependent on the stiffness of the ac bus, it is connected to. With the traditional synchronous reference frame-phase locked loops (SRF-PLL), voltage source converters (VSC) ...
Electrode-based wireless passive pH sensors with applications to bioprocess and food spoilage monitoring
(IEEEIEEEIEEEElsevierElsevier, 2011-11)
This thesis purposes and develops inductively coupled LC (inductive-capacitive) pH sensors based on pH-sensitive electrode pair. The LC resonator circuit is based on a varactor and measures the low frequency potential ...
Directive microstrip disc radiators based on TM1m modes
(IEEE TAP, 2016)
Fundamental TM11 mode of circular microstrip antennas has a limitation of low broadside gain. This thesis explores and investigates the possibility of designing high gain circular microstrip antennas by using higher zeros ...
Radar cross section data inversion for snow-covered sea ice remote sensing
(2015)
This thesis reports on my Ph.D. research in the area of microwave remote sensing of the Arctic. The main objective of this research is to reconstruct the dielectric profile of the snow-covered sea ice, and indirectly ...
