Chaos and Localisation
… of classical diffusion, known as dynamical localisation, and quantum resonances as a regime of enhanced transport for the delta-kicked rotor. The first part of the thesis provides new support for the quantitative analogy between energy transport in strongly driven highly excited atoms and …

Tumour Localisation in Histopathology Images
… important for understanding the distribution and localisation of biomarkers at the cellular level. However currently IHC analyses are predominantly performed manually, increasing workloads and introducing inter- and intra-observer variability. Automation shows great potential in clinical research …

Pedestrian localisation for indoor environments
… calculating a pedestrian’s relative movements, a localisation filter is developed that combines relative movement measurements with environmental constraints derived from a map of the environment. By enforcing constraints such as impassable walls and floors the filter is able to narrow down the …

Localisation under Large Appearance Change
Localisation is a foundational building block for more complex robot applications, and thus if low-cost localisation solutions can be found, the number of activities a robot can undertake will increase. However, appearance-based localisation systems in the past have required frequent traversals of …

Landmark localisation in 3D face data
Accurate landmark localisation is an essential precursor to many 3D face processing algorithms but, as yet, there is a lack of convincing solutions that work well over a wide range of head poses. In this thesis, an investigation to localise facial landmarks from 3D images is presented, without …

Smartphone-based robot control for localisation
… as input to trigger mobile robot movement for localisation purpose. The input sensor is designed to generate DTMF tone based on North Pole direction and force the robot to move only one direction referenced by North Pole. Several analyses have been done such as network provider analysis, robot …

Geometry model for marker-based localisation
… mobile robots since the early 2000s, and yet localisation in a dynamic environmentthat form the main building block of navigation, has no truly elegant solution.Solutions are many and their strategies and methods differ depending on theapplication. For the lack of a single accurate procedure, …

Probablistic approaches for intelligent AUV localisation
This thesis studies the problem of intelligent localisation for an autonomous underwater vehicle (AUV). After an introduction about robot localisation and specific issues in the underwater domain, the thesis will focus on passive techniques for AUV localisation, highlighting experimental results …

The localisation of Experimentally Evoked Dental Pain : an exploration of an intervention to improve the accuracy of localisation
<b>Background</b>: The accurate localisation of the symptomatic tooth with pulpal pain could be very difficult for the dental patient and a challenging situation for the dentists. Objectives: This study aimed to determine the localisation accuracy of induced dental pain under a highly controlled …

MOTION CONTROL AND LOCALISATION OF ROBOTIC FISH
Biological fishes are efficient swimmers, exhibiting many desirable features such as high power efficiency while minimal noise to the surroundings. Such characteristics are highly desirable in underwater robots and hence, learning from nature, robotic fishes have been invented. Prior to mimicking …

Multi-session Visual Simultaneous Localisation and Mapping
… map. This problem is referred to as Simultaneous Localisation and Mapping (or SLAM). Over the past 25 years considerable progress has been made on the SLAM problem with a large number of solutions being reported in the literature. Although the majority of earlier systems depended on active ranging …

Minimal Infrastructure Radio Frequency Home Localisation Systems
… and development of a home roomlevel localisation technique which can be readily deployed in a realistic home environment with minimal hardware requirements. A conveniently deployed Bluetooth ® localisation platform is designed and experimentally validated throughout the thesis. The …

Discontinuous modelling of strain localisation and failure
The computational simulation of failure in solids poses many challenges. A proper understanding of how structures respond under loading, both before and past the peak load, is important for safe and economical constructions. This requires numerical models for failure which are both faithful to the …

The subnuclear localisation of Notch responsive genes
Title: The subnuclear localisation of Notch responsive genes. Candidate Name: Matthew Jones Notch signalling is a highly conserved cell-cell communication pathway with critical roles in metazoan development and mutations in Notch pathway components are implicated in many types of cancer. Notch is …

Sonar beamforming based upon monaural localisation techniques
… reflector – the ear. A study of monaural localisation was therefore undertaken, with a view to the development of a novel beamforming system which uses only a single active element. Computer simulations have shown that the direction of a source can be determined by cross –correlating the …

Audio-based localisation for ubiquitous sensor networks
… machine listening history. An active audio self-localisation algorithm is described which is effective in distributed sensor networks even if only coarse temporal synchronisation can be established. Pseudo-noise 'chirps' are emitted and recorded at each of the nodes. Pair-wise distances are …

Improving Information Retrieval Bug Localisation Using Contextual Heuristics
… code prior to performing maintenance tasks. Bug localisation is a core program comprehension activity in software maintenance: given the observation of a bug, e.g. via a bug report, where is it located in the source code? Information retrieval (IR) approaches see the bug report as the query, and …

Localisation of Bose-Einstein condensates in optical lattices
The properties of Bose-Einstein condensates can be studied and controlled effectively when trapped in optical lattices formed by two counter-propagating laser beams. The dynamics of Bose-Einstein condensates in optical lattices are well-described by a continuous model using the Gross-Pitaevskii …

Intelligent energy efficient localisation in wireless sensor networks
A wireless sensor network comprises of tiny sensor nodes which communicate with each other through radio frequency communication links. In many applications of wireless sensor networks, the sensor nodes collect data or detect an event and report it to a central node for further processing. Location …
