Teaching Robots Social Autonomy From In Situ Human Supervision, Emmanuel Senft
Teaching Robots Social Autonomy From In Situ Human Supervision, Emmanuel Senft
School of Engineering, Computing and Mathematics Theses
Traditionally the behaviour of social robots has been programmed. However, increasingly there has been a focus on letting robots learn their behaviour to some extent from example or through trial and error. This on the one hand excludes the need for programming, but also allows the robot to adapt to circumstances not foreseen at the time of programming. One such occasion is when the user wants to tailor or fully specify the robot’s behaviour. The engineer often has limited knowledge of what the user wants or what the deployment circumstances specifically require. Instead, the user does know what is expected …
Ergodicity Of The Llr Method For The Density Of States, Guido Cossu, Biagio Lucini, Roberto Pellegrini, Antonio Rago
Ergodicity Of The Llr Method For The Density Of States, Guido Cossu, Biagio Lucini, Roberto Pellegrini, Antonio Rago
School of Engineering, Computing and Mathematics
The LLR method is a novel algorithm that enables us to evaluate the density of states in lattice gauge theory. We present our study of the ergodicity properties of the LLR algorithm for the model of Yang Mills SU(3). We show that the use of the replica exchange method alleviates significantly the topological freeze-out that severely affects other algorithms.

Tsunami Generation By Combined Fault Rupture And Landsliding, Del Postigo Prieto N Perez, A Raby, Sj Boulton, C Whittaker
School of Engineering, Computing and Mathematics
Tsunami generation and propagation mechanisms should be clearly understood in order to inform predictive models and improve coastal community preparedness. Experimental results, supported by mathematical models, could potentially provide valuable input data for standard predictive models of tsunami generation and propagation. A unique set-up has been developed to reproduce a dual-source tsunami generation mechanism. The test-rig replicates a two-dimensional underwater fault rupture followed by a submarine landslide. The set-up was placed in a 20m flume of the COAST laboratory at Plymouth University. The aim of the experiments is to provide quality data for developing a parametrization of the initial conditions …

The autonomous landing of an unmanned aerial vehicle (UAV) is still an open problem. Previous work focused on the use of hand-crafted geometric features and sensor-data fusion for identifying a fiducial marker and guide the UAV toward it. In this article we propose a method based on deep reinforcement learning that only requires low-resolution images coming from a down looking camera in order to drive the vehicle. The proposed approach is based on a hierarchy of Deep Q-Networks (DQNs) that are used as high-end control policy for the navigation in different phases. We implemented various technical solutions, such as the …

Bayesian Hierarchical Models For Linear Networks, Zainab A A Al-Kaabawi
School of Engineering, Computing and Mathematics Theses
A motorway network is handled as a linear network. The purpose of this study is to highlight dangerous motorways via estimating the intensity of accidents and study its pattern across the UK motorway network. Two mechanisms have been adopted to achieve this aim. The first, the motorway-specific intensity is estimated by modelling the point pattern of the accident data using a homogeneous Poisson process. The homogeneous Poisson process is used to model all intensities but heterogeneity across motorways is incorporated using two-level hierarchical models. The data structure is multilevel since each motorway consists of junctions that are joined by grouped …

Action Learning Experiments Using Spiking Neural Networks And Humanoid Robots, Ricardo De Azambuja
School of Engineering, Computing and Mathematics Theses
The way our brain works is still an open question, but one thing seems to be clear: biological neural systems are computationally powerful, robust and noisy. Natural nervous system are able to control limbs in different scenarios with high precision. As neural networks in living beings communicate through spikes, modern neuromorphic systems try to mimic them by using spike-based neuron models. This thesis is focused on the advancement of neurorobotics or brain inspired robotic arm controllers based on artificial neural network architectures. The architecture chosen to implement those controllers was the spike neuron version of Reservoir Computing framework, called Liquid …

The use of plastics has spanned across almost all aspects of day to day life. Although their uses are invaluable, they contribute to the generation of a lot of waste products that end up in the environment and end up polluting natural habitats such as forests and the ocean. By treating low-density polyethylene (LDPE) samples with non-thermal plasma in ambient air and with an addition of ≈4% CO2, the biodegradation of the samples can be increased due to an increase in oxidative species causing better cell adhesion and acceptance on the polymer sample surface. It was, however, found that the …
