The book provides a pedagogical approach that emphasizes the physical processes of active materials and the design and control of engineering systems. It will also be a reference text for practicing engineers who might understand the basic principles of active materials but have an interest in learning more about specific applications. The text includes a number of worked examples, design problems, and homework problems (with a solutions manual) that will be useful for both instructors and practicing engineers.

One of the fundamental requirements for the success of a robot task is the capability to handle interaction between manipulator and environment. The quantity that describes the state of interaction more effectively is the contact force at the manipulator's end effector. High values of contact force are generally undesirable since they may stress both the manipulator and the manipulated object; hence the need to seek for effective force control strategies. The book provides a theoretical and experimental treatment of robot interaction control. In the framework of model-based operational space control, stiffness control and impedance control are presented as the basic strategies for indirect force control; a key feature is the coverage of six-degree-of-freedom interaction tasks and manipulator kinematic redundancy. Then, direct force control strategies are presented which are obtained from motion control schemes suitably modified by the closure of an outer force regulation feedback loop. Finally, advanced force and position control strategies are presented which include passivity-based, adaptive and output feedback control schemes. Remarkably, all control schemes are experimentally tested on a setup consisting of a seven-joint industrial robot with open control architecture and force/torque sensor. The topic of robot force control is not treated in depth in robotics textbooks, in spite of its crucial importance for practical manipulation tasks. In the few books addressing this topic, the material is often limited to single-degree-of-freedom tasks. On the other hand, several results are available in the robotics literature but no dedicated monograph exists. The book is thus aimed at filling this gap by providing a theoretical and experimental treatment of robot force control.

Environmental and social performance measurement and reporting by business has become a high-profile issue during the 1990s. It is increasingly being requested by stakeholders and required by governments. Companies too are finding that they need better environmental and social performance data for effective internal management. And there are a growing number of standardisation initiatives – such as the ISO 14031 guidelines on environmental performance evaluation or the CERES Global Reporting Initiative (GRI) template for sustainability reporting – that are aimed at making it easier for more companies to take action, and for stakeholders to compare their progress.Sustainable Measures collects together most of the key work and individuals concerned with the topic from around the world. Contributions include: environmental and social reporting by John Elkington and colleagues at SustainAbility; the GRI discussion draft; Roger Adams and Martin Houldin on the FEE study of environmental reporting; Janet Ranganathan of the World Resources Institute on sustainability measures; and Martin Bennett and Peter James on ISO 14031 and the future of environmental performance evaluation. There are also chapters examining current practice in Austria, Denmark, India, Indonesia, Japan, the Netherlands and South Africa, developments in electronic reporting, as well as case studies of Baxter, Kunert, Niagara Mohawk, Unox, The Body Shop and the UK water industry, and an analysis of leading social reports.The book is essential reading for all academics, campaigners, policy-makers and practitioners with an interest in issues such as:The standardization and comparability of environmental and social performance measuresMeasuring and reporting on sustainable businessEco-points and other means of evaluating product impactsThe implementation of measurement and reportingBest practice in corporate environmental and social reportingNew means of communicating environmental dataEnvironmental performance evaluation in developing countries
