Activity understanding and unusual event detection in surveillance videos
(2010)
Computer scientists have made ceaseless efforts to replicate cognitive video understanding abilities
of human brains onto autonomous vision systems. As video surveillance cameras become
ubiquitous, there is a surge in ...
Collaborating through sounds: audio-only interaction with diagrams
(2010)
The widening spectrum of interaction contexts and users’ needs continues to expose the limitations
of the Graphical User Interface. But despite the benefits of sound in everyday activities and
considerable progress in ...
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 ...
Automating quantitative information flow
(2011)
Unprecedented quantities of personal and business data are collected, stored,
shared, and processed by countless institutions all over the world. Prominent
examples include sharing personal data on social networking ...
Simple low cost causal discovery using mutual information and domain knowledge
(2011)
This thesis examines causal discovery within datasets, in particular observational datasets where
normal experimental manipulation is not possible. A number of machine learning techniques
are examined in relation to ...
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 ...
Discourses of desire: the normative in online sex talk
(2011)
This thesis, grounded in feminist sociology and queer theory, examines sex, sexuality, and desire in naturally occurring synchronous conversations within a non-sexually themed online community. Although the community is ...
An intelligent radio access network selection and optimisation system in heterogeneous communication environments
(2010)
The overlapping of the different wireless network technologies creates heterogeneous communication environments. Future mobile communication system considers the technological and operational services of heterogeneous ...
Strategies for image visualisation and browsing
(2010)
The exploration of large information spaces has remained a challenging task even
though the proliferation of database management systems and the state-of-the art
retrieval algorithms is becoming pervasive. Signi cant ...
Biologically inspired, self organizing communication networks.
(2011)
The problem of energy-efficient, reliable, accurate and self-organized target tracking in
Wireless Sensor Networks (WSNs) is considered for sensor nodes with limited physical
resources and abrupt manoeuvring mobile ...
