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 ...
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 ...
Cooperative relay beamforming design for multi-cluster relay interference networks
(2016-08-01)
In this work, we consider a multi-cluster amplified-and-forward (AF) relay interference
network and design relay beam matrix for each cluster to maximize the minimum
signal-to-interference-and-noise ratio (SINR) at ...
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 ...
Design optimization of active trailer differential braking systems for car-trailer combinations
(2016-01-01)
The thesis studies active trailer differential braking (ATDB) systems to improve the lateral stability of car-trailer (CT) combinations. CT combinations exhibit unique unstable motion modes, including jack-knifing, trailer ...
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 ...
Enhancing geothermal heat pump systems with parametric performance analyses
(2010-04-01)
Parametric performance analyses and comparison of a basic geothermal heat pump, a heat pump cycle with motor cooling/refrigerant preheating, and a heat pump cycle utilizing an economizer with respect to first law is conducted ...
