Compressive Sensing for Microwave and Millimeter-Wave Array Imaging
(Queen Mary University of London, 2018-01-08)
Compressive Sensing (CS) is a recently proposed signal processing technique that has
already found many applications in microwave and millimeter-wave imaging. CS theory
guarantees that sparse or compressible signals can ...
Investigating the design of Smart Objects in the domain of forgetfulness
(Queen Mary University of London, 2018-06-01)
When we forget things, we feel anxious which can impact our day negatively. Some
individuals believe they are forgetful, so emphatically, it disrupts their day. There has been
little discussion about perceived forgetfulness ...
Active and Reconfigurable Millimetre-Wave Antennas and Systems
(Queen Mary University of London, 2018-06-05)
The millimetre-wave (mm-wave) spectrum offers considerable advantages in terms of antenna form factor and spectrum availability. However, use of this region often requires reconfigurable antennas and systems. Initially, a ...
Presentation of Visual Artworks in Interactive Virtual Environments towards User Engagement
(Queen Mary University of London, 2018-05-24)
This thesis explores the role of interactivity in interfaces for visual artwork display, and the promotion of user engagement. In contrast to most previous work, which has been based on digitally recreating the physical ...
Human activity recognition using a wearable camera
(Queen Mary University of London, 2018-05-14)
Advances in wearable technologies are facilitating the understanding of human activities using
first-person vision (FPV) for a wide range of assistive applications. In this thesis, we propose
robust multiple motion ...
Intersubjectivity, Empathy and Nonverbal Interaction
(Queen Mary University of London, 2018-04-24)
Empathy is thought to involve cognitive processes that depend on the simulation of another's
experiences. Embodiment has a key role for empathy as vehicle for recreating the experience
of another. This thesis explores ...
Energy Efficient Channel Access Mechanism for IEEE 802.11ah based Networks
(Queen Mary University of London, 2018-01-03)
IEEE 802.11ah is designed to support battery powered devices that are required to serve
for several years in the Internet of Things networks. The Restricted Access Window
(RAW) has been introduced in IEEE 802.11ah to ...
Robust Subspace Estimation via Low-Rank and Sparse Decomposition and Applications in Computer Vision
(Queen Mary University of London, 2018-01-16)
Recent advances in robust subspace estimation have made dimensionality reduction and
noise and outlier suppression an area of interest for research, along with continuous
improvements in computer vision applications. Due ...
Design, Analysis, and Applications of Optically-Activated Antennas and Dielectric Lenses Using Photosensitive Semiconducting Materials
(Queen Mary University of London, 2018-06-05)
The primary objective of the research is to investigate photosensitive semiconducting materials, mainly organic, and utilise them in antenna front-end systems and dynamic lenses for sub-THz applications. Mechanisms such ...
A Terahertz Holography Imaging System for Concealed Weapon Detection Application
(Queen Mary University of London, 2018-01-08)
Many research groups have conducted the investigation into terahertz technology for various applications over the last decade. THz imaging for security screening has been one of the most important applications because of ...
