FDTD modelling of electromagnetic transformation based devices
(2010)
During this PhD study, several finite-difference time-domain (FDTD) methods were
developed to numerically investigate coordinate transformation based metamaterial
devices. A novel radially-dependent dispersive FDTD ...
Topology and congestion invariant in global internet-scale networks
(2010)
Infrastructures like telecommunication systems, power transmission
grids and the Internet are complex networks that are vulnerable to
catastrophic failure. A common mechanism behind this kind of failure
is avalanche-like ...
Particle swarm optimization for routing and wavelength assignment in next generation WDM networks.
(2010)
All-optical Wave Division Multiplexed (WDM) networking is a promising technology for long-haul backbone and large metropolitan optical networks in order to meet the non-diminishing bandwidth demands of future applications ...
Packet level measurement over wireless access
(2011)
Performance Measurement of the IP packet networks mainly comprise of monitoring the network performance in terms of packet losses and delays. If used appropriately, these network parameters (i.e. delay, loss and bandwidth ...
Trajectory based video analysis in multi-camera setups
(2010)
This thesis presents an automated framework for activity analysis in multi-camera
setups. We start with the calibration of cameras particularly without overlapping
views. An algorithm is presented that exploits trajectory ...
Surveillance centric coding
(2011)
The research work presented in this thesis focuses on the development of techniques
specific to surveillance videos for efficient video compression with higher processing
speed. The Scalable Video Coding (SVC) techniques ...
A novel multimedia adaptation architecture and congestion control mechanism designed for real-time interactive applications
(2011)
The increasing use of interactive multimedia applications over the Internet has created a problem of congestion. This is because a majority of these applications do not respond to congestion indicators. This leads to ...
Towards automatic extraction of harmony information from music signals
(2010)
In this thesis we address the subject of automatic extraction of harmony
information from audio recordings. We focus on chord symbol recognition
and methods for evaluating algorithms designed to perform that task.
We ...
Automatic chord transcription from audio using computational models of musical context
(2010)
This thesis is concerned with the automatic transcription of chords from audio, with an emphasis
on modern popular music. Musical context such as the key and the structural segmentation aid
the interpretation of chords ...
Representation and recognition of human actions in video
(2011)
Automated human action recognition plays a critical role in the development of human-machine
communication, by aiming for a more natural interaction between artificial intelligence and the
human society. Recent developments ...
