Channel estimation in a two-way relay network
(2011-08-01)
In wireless communications, channel estimation is necessary for coherent symbol detection.
This thesis considers a network which consists of two transceivers communicating
with the help of a relay applying the amplify-and-forward ...
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 ...
Novel opposition-based sampling methods for efficiently solving challenging optimization problems
(2011-04-01)
In solving noise-free and noisy optimization problems, candidate initialization and sampling
play a key role, but are not deeply investigated. It is of interest to know if the entire
search space has the same quality for ...
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 ...
Haptic teleoperation of mobile manipulator systems using virtual fixtures.
(2011-11-01)
In order to make the task of controlling Mobile-Manipulator Systems (MMS) simpler, a
novel command strategy that uses a single joystick is presented to replace the existing
paradigm of using multiple joysticks. To improve ...
Energy ans exergy analysis of biomass co-firing in pulverized coal power generation
(2011-04-01)
Biomass co-firing with coal exhibits great potential for large scale utilization of biomass
energy in the near future. In the present work, energy and exergy analyses are carried out
for a co-firing based power generation ...
CBPsp: complex business processes for stream processing
(2011-04-01)
This thesis presents the framework of a complex business process driven event
stream processing system to produce meaningful output with direct implications to the
business objectives of an organization. This framework is ...
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 ...
