This work is concerned with the simultaneous tracking and shape estimation of a mobile extended object based on noisy sensor measurements. Novel methods are developed for coping with the following two main challenges: i) The computational complexity due to the nonlinearity and high-dimensionality of the problem and ii) the lack of statistical knowledge about possible measurement sources on the extended object.

The complexity of technical systems increases, breakdowns occur quite often. The mission of organic computing is to tame these challenges by providing degrees of freedom for self-organised behaviour. To achieve these goals, new methods have to be developed. The proposed observer/controller architecture constitutes one way to achieve controlled self-organisation. To improve its design, multi-agent scenarios are investigated. Especially, learning using learning classifier systems is addressed.

Extended object tracking deals with estimating the shape and pose of an object based on noisy point measurements. This task is not straightforward, as we may be faced with scarce low-quality measurements, little a priori information, or we may be unable to observe the entire target. This work aims to address these challenges by incorporating ideas from active contours and exploiting information from negative measurements, which tell us where the target cannot be.

A physically-based dislocation theory of plasticity is derived within an extended continuum mechanical context. Thermodynamically consistent flow rules at the grain boundaries are derived. With an analytical solution of a three-phase periodic laminate, dislocation pile-up at grain boundaries and dislocation transmission through the grain boundaries are investigated. For the finite element implementations, numerically efficient approaches are introduced based on accumulated field variables.

This volume addresses the current debate on extended working life policy by considering the influence of gender and health on the experiences of older workers. Bringing together an international team of scholars, it tackles issues as gender, health status and job/ occupational characteristics that structure the capacity and outcomes associated with working longer. The volume starts with an overview of the empirical and policy literature; continues with a discussion of the relevant theoretical perspectives; includes a section on available data and indicators; followed by 25 very concise and unique country reports that highlight the main extended working life (EWL) research findings and policy trajectories at the national level. It identifies future directions for research and addresses issues associated with effective policy-making. This volume fills an important gap in the knowledge of the consequences of EWL and it will be an invaluable source for both researchers and policy makers. .

Recent years have seen a number of initiatives which seek to provide a range of community services on school sites, including adult education and other social and welfare services. These developments aim at co-ordinating more effectively services which are usually provided separately while optimizing the use of increasingly sophisticated and expensive educational buildings and equipment. However, providing integrated services "under one roof" poses a number of practical problems. What is the rationale for integrated service provision? What are the implications for the local authorities, planners and architects in charge of designing school sites that meet new requirements? This report presents the main lessons learned from a conference held in Stockholm, drawing on case studies from Finland, Italy, Japan, the Netherlands, Quebec, Sweden and the United Kingdom. The case studies provide a wealth of examples of solutions to the challenge of optimizing the use of existing schools by better integrating them into local communities and by promoting new synergies with other services.

Intended to introduce readers to the use of artificial neural networks in the study of music, this volume contains numerous case studies and research findings that address problems related to identifying scales, keys, classifying musical chords, and learning jazz chord progressions. A detailed analysis of networks is provided for each case study which together demonstrate that focusing on the internal structure of trained networks could yield important contributions to the field of music cognition.

Unmanned aerial vehicles (UAVs) are being increasingly used in different applications in both military and civilian domains. These applications include surveillance, reconnaissance, remote sensing, target acquisition, border patrol, infrastructure monitoring, aerial imaging, industrial inspection, and emergency medical aid. Vehicles that can be considered autonomous must be able to make decisions and react to events without direct intervention by humans. Although some UAVs are able to perform increasingly complex autonomous manoeuvres, most UAVs are not fully autonomous; instead, they are mostly operated remotely by humans. To make UAVs fully autonomous, many technological and algorithmic developments are still required. For instance, UAVs will need to improve their sensing of obstacles and subsequent avoidance. This becomes particularly important as autonomous UAVs start to operate in civilian airspaces that are occupied by other aircraft. The aim of this volume is to bring together the work of leading researchers and practitioners in the field of unmanned aerial vehicles with a common interest in their autonomy. The contributions that are part of this volume present key challenges associated with the autonomous control of unmanned aerial vehicles, and propose solution methodologies to address such challenges, analyse the proposed methodologies, and evaluate their performance.
