Coded aperture imaging application in one-sided imaging of visually obscured objects
(2011-05-17)
The physical properties of visible light and its interaction with matter create
obstructions the human eye cannot explore. High energy radiation has been
used as an alternative to visible light to penetrate these concealed ...
Performance trade-off analysis in bidirectional network beamforming.
(2011-10-01)
This research examines a two-way relay network consisting of two transceivers and
multiple parallel relays, which are equipped with single antennas and operate in a halfduplex
mode. In this system, the two transceivers ...
Characterization of natural fibre reinforced biodegradable composities
(2011-08-01)
Low cost, light weight, recyclability, and high specific strength of natural fibres make them a good replacement for synthetic fibre such as glass in fibre reinforced plastics (FRP). Green and ecofriendly source of these ...
Evaluating and improving collection tree protocol in mobile wireless sensor network
(2011-07-01)
There has been growing interest in the Mobile WSN applications where mobility is
the fundamental characteristic of the sensor nodes. Mobility poses many challenges
to the routing protocols used in such applications. In ...
Design and optimization of a three-fingered robot hand
(2011-04-01)
Humanoid robots have proven to be very useful and could revolutionize the way humans
live. Knowing human anatomy and behaviour helps improve a robotic mechanisms
ability to perform human tasks. The following thesis introduces ...
Transmutation rates in the annulus gas of pressure tube water reactors
(2011-07-01)
CANDU (CANada Deuterium Uranium) reactor utilizes Pressure Tube (PT) fuel channel design and heavy water as a coolant. Fuel channel annulus gas acts as an insulator to minimize heat losses from the coolant to the moderator. ...
Experimental investigation of an R134a based organic Rankine cycle
(2011-08-01)
This thesis research aims to develop an improved, efficient, low-capacity heat engine, running
on an Organic Rankine Cycle (ORC) to generate power. The ORC is driven by low or
moderate temperature heat sources, such as; ...
Data hiding and detection in Office Open XML (OOXML) documents
(2011-03-01)
With the rapid development and popularity of information technology, criminals and mischievous computer users are given avenues to commit crimes and malicious activities. One of the commonly used tactics, called steganography, ...
Effective design of multiplexing network for applications in communications satellites
(2011-07-01)
Microwave multiplexing networks are widely used in satellite communication systems. Their performances, such as the insertion loss and rejection between channels, are extremely critical. This research aims at effective ...
Experimental investigation of scroll based organic Rankine systems
(2011-04-01)
In this thesis, an experimental research is conducted on scroll-based Organic Rankine Cycle (ORC) focusing on the expansion process. An important feature of the ORC is the ability to utilize low or moderate temperature ...
