	Bayesian Gaussian Process models for multi-sensor time-series prediction
	We propose a powerful prediction algorithm built upon Gaussian processes (GPs). They are particularly useful for their flexibility, facilitating accurate prediction even in the absence of strong physical models. GPs further allow us to work within a completely Bayesian framework. As such, we show how the hyperparameters of our system can be marginalised by use of Bayesian Monte Carlo, a principled method of approximate integration. We employ the error bars of the GP's prediction as a means to select only the most informative observations to store. This allows us to introduce an iterative formulation of the GP to give a dynamic, on-line algorithm. We also show how our error bars can be used to perform active data selection, allowing the GP to select where and when it should next take a measurement. We demonstrate how our methods can be applied to multi-sensor prediction problems where data may be missing, delayed and/or correlated. In particular, we present a real network of weather sensors as a testbed for our algorithm.

	Numerical methods for finding periodic solutions of dynamical systems
	Recurrences have been central to the study of dynamical systems ever since the inception of the subject. Periodic solutions make the notion of recurrences exact. The Lorenz attractor is the best known example of a strange attractor and we will describe a method to find periodic solutions that lie on it. Additionally, we will consider a turbulent channel flow and describe the computation of time periodic solutions using nearly $300,000$ degrees of freedom to represent the velocity field.
