Vibration suppression of straight and curved beams traversed by moving loads
(2011-09-01)
Vibration suppression of beams traversed by moving loads, using optimal Tuned-Mass-Damper (TMD) systems, is investigated. This study is performed on two different geometrical shapes of the beam, namely, uniform homogenous ...
Modeling of voltage source converter based HVDC transmission system in EMTP-RV
(2010-08-01)
Voltage Source Converter (VSC) applications include but are not limited to HVDC, Flexible AC Transmission System (FACTS) devices such as STATCOM, SSSC, UPFC and Wind generators and active filters. The VSC based HVDC system ...
Energy-efficient relay cooperation for lifetime maximization
(2011-08-01)
We study energy-efficient power allocation among relays for lifetime maximization
in a dual-hop relay network operated by amplify-and-forward relays with battery
limitations. Power allocation algorithms are proposed for ...
Improved design of three-degree of freedom hip exoskeleton based on biomimetic parallel structure
(2011-07-01)
The external skeletons, Exoskeletons, are not a new research area in this highly
developed world. They are widely used in helping the wearer to enhance human strength,
endurance, and speed while walking with them. Most ...
Forensic analysis of unallocated space
(2011-06-01)
Computer forensics has become an important technology in providing evidence in investigations of computer misuse, attacks against computer systems and more traditional crimes like money laundering and fraud where digital ...
Interactive visualization of the collaborative research network
(2012-01-01)
Social networks have been evolving over the past few years, leading to a rapid increase in the number and complexity of relationships among their entities. In this research, we focus on a large scale dataset known as the ...
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 ...
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 ...
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; ...
