New Techniques for Learning Parameters in Bayesian Networks.
(Queen Mary University of London, 2015-08)
One of the hardest challenges in building a realistic Bayesian network (BN) model is
to construct the node probability tables (NPTs). Even with a fixed predefined model
structure and very large amounts of relevant data, ...
Recognition of Sound Sources and Acoustic Events in Music and Environmental Audio
(Queen Mary University of London, 2014)
Hearing, together with other senses, enables us to perceive the surrounding world through sensory
data we constantly receive. The information carried in this data allow us to classify the
environment and the objects in ...
Energy-Efficient Location Determination for Human Mobility Analysis and Monitoring Using Smart Mobile Devices
(Queen Mary University of London, 2014)
Embedded smartphone sensors such as GPS and Wi-Fi have the ability to capture location information. These sensors are increasingly being used for location determination to enable Location based services (LBS) such as maps ...
The Effect of Audio Cues and Sound Source Stimuli on Looming Perception.
(Queen Mary University of London, 2015-01)
Objects that move in depth (looming) are ubiquitous in the real and virtual worlds. How
humans interact and respond to these approaching objects may affect their continued
survival in both the real and virtual words, and ...
Sparse Representations & Compressed Sensing with application to the problem of Direction-of-Arrival estimation.
(Queen Mary University of London, 2013-06)
The significance of sparse representations has been highlighted in numerous signal processing
applications ranging from denoising to source separation and the emerging field
of compressed sensing has provided new theoretical ...
Wearable RF sensors for non-invasive detection of blood-glucose levels
(Queen Mary University of London, 2013-09)
Radio frequency (RF) techniques have the potential to provide blood glucose
readings through sensing the glucose dependent change in dielectric properties of
the biological tissue. Such technique can enable much desired ...
Planning Simulation Run Length in Packet Queues in Communications Networks
(Queen Mary University of London, 2013-05)
Simulation is a technique of growing importance and is becoming an indispensable
tool applied in various academic industries, including packet networks.
Simulation provides an alternative research approach to implementing ...
Semantic Audio Analysis Utilities and Applications.
(Queen Mary University of London, 2012-04)
Extraction, representation, organisation and application of metadata about audio recordings
are in the concern of semantic audio analysis. Our broad interpretation, aligned with recent
developments in the field, includes ...
Research and design of non-Foster active metamaterials
(2013-07)
During this PhD study, metamaterials incorporating active devices such as varactors and
non-Foster circuits, were researched and designed. Starting from the research on tuneable
metamaterials, an electronically controlled ...
Session Types, Concurrent Separation Logic & Algebra
(Queen Mary University of London, 2013-03)
This dissertion explores the relation between two formalisms and one algebraic framework
for concurrency. Session Types and Concurrent Separation Logic are formalisms that support
independent reasoning about concurrent ...
