  • This thesis addresses two neural network based control systems. The first is a neural network based predictive controller. System identification and controller design are discussed. The second is a direct neural network controller. Parameter choice and training methods are discussed. Both controllers are tested on two different plants. Problems regarding implementations are discussed. First the neural network based predictive controller is introduced as an extension to the generalised predictive controller (GPC) to allow control of non-linear plant.

  • The current control problems present natural trend of increasing its complexity due to performance criteria that is becoming more sophisticated. The necessity of practicers and engineers in dealing with complex dynamic systems has motivated the design of controllers, whose structures are based on multiobjective constraints, knowledge from expert, uncertainties, nonlinearities, parameters that vary with time, time delay conditions, multivariable systems, and others.

  • This work is intended to survey the basic theory that underlies the multitude of parameter-rich models that dominate the hydrological literature today. It is concerned with the application of the equation of continuity (which is the fundamental theorem of hydrology) in its complete form combined with a simplified representation of the principle of conservation of momentum. Since the equation of continuity can be expressed in linear form by a suitable choice of state variables and is also parameterfree, it can be readily formulated at all scales of interest.

  • The goal of the first edition of this textbook was to present a comprehensive engineering basis for photovoltaic (PV) system design, so the engineer would understand the what, the why and the how associated with electrical, mechanical, economic and aesthetic aspects of PV system design. The first edition was intended to educate the engineer in the design of PV systems so that when engineering judgment was needed, the engineer would be able to make intelligent decisions based upon a clear understanding of the parameters involved.

  • Different PHI functions give rise to specific policy challenges. Primary PHI markets often create access-related challenges, especially for high-risk and vulnerable groups, where they represent the sole form of cover for some population groups.15 Where public and private delivery systems are linked to different funding sources, as in systems with duplicate private health insurance, differences in access to care, choice levels and utilisation patterns occur between individuals with and without private insurance.

  • Sympathetic nerve stimulation induces vasoconstriction and consequent decreases nasal airway resistance. Parasympathetic nerve stimulation on the other hand, promotes secretion from nasal airway glands and nasal congestion. The nasal mucosa also contains nerves of the non-adrenergic, non-cholinergic (NANC)- system. Neuropeptides from the latter nerves (substance P, neurokinin A and K, and calcitonin gene-related peptide) are suspected to play a role in vasodilatation, mucus secretion, plasma extravasation, neurogenic inflammation, and mast cell nerve interactions.

  • In recent years the marine transportation system has come under increasing attention. Among the concerns are its safety and efficiency, prevention of and response to ship-caused pollution, and the use of vessels for inimical purposes, ranging from simple lawbreaking (such as smuggling) to serving as a vehicle or target for terrorist acts. Over the past two decades, automatic identification systems (AIS) have been developed in response to these concerns, and much work has been done to define AIS technical and communication requirements.

  • State-of-the-art Machine Translation (MT) systems are still far from being perfect. An alternative is the so-called Interactive Machine Translation (IMT) framework, where the knowledge of a human translator is combined with the MT system. We present a statistical IMT system able to learn from user feedback by means of the application of online learning techniques. These techniques allow the MT system to update the parameters of the underlying models in real time.

  • Statistical language modeling (SLM) has been used in many different domains for decades and has also been applied to information retrieval (IR) recently. Documents retrieved using this approach are ranked according their probability of generating the given query. In this paper, we present a novel approach that employs the generalized Expectation Maximization (EM) algorithm to improve language models by representing their parameters as observation probabilities of Hidden Markov Models (HMM).

  • Current turn-taking approaches for spoken dialogue systems rely on the speaker releasing the turn before the other can take it. This reliance results in restricted interactions that can lead to inefficient dialogues. In this paper we present a model we refer to as Importance-Driven Turn-Bidding that treats turn-taking as a negotiative process. Each conversant bids for the turn based on the importance of the intended utterance, and Reinforcement Learning is used to indirectly learn this parameter. ...
