What can architects, landscape architects and urban designers do to make urban open spaces, streets and squares, more responsive, lively and safe? Urban Sustainability through Environmental Design answers this question by providing the analytical tools and practical methodologies that can be employed for sustainable solutions to the design and management of urban environments. The book calls into question the capability of 'quick-fix' development solutions to provide the establishment of fixed communities and suggests a more time-conscious and evolutionary approach. This is the first significant book to draw together a pan-European view on sustainable urban design with a specific focus on social sustainability. It presents an innovative approach that focuses on the tools of urban analysis rather than the interventions themselves. With its practical approach and wide-ranging discussion, this book will appeal to all those involved in producing communities and spaces for sustainable living, from students to academics through to decision makers and professional leaders.

A first attempt to develop a standardized agent communication language (ACL) resulted in KQML, probably the most widely used such language. However, a lot of technical work remains to be done. Even worse, so far, there seems to be little consensus on the basics of agent communication and there is no clear understanding of the semantics of individual speech acts or even of the basic concepts that should be used to define the semantics.This book documents two workshops on communication in MAS held in 1999, one on Specifying and Implementing Conversation Policies (SICP) and the other in Agent Communication Languages and presents the current state of the art of research in the field. A detailed introductory overview by the volume editors highlights a number of issues that play an important role in agent communication.

The use of diagrams in logic and geometry has encountered resistance in recent years. For a proof to be valid in geometry, it must not rely on the graphical properties of a diagram. In logic, the teaching of proofs depends on sentenial representations, ideas formed as natural language sentences such as "If A is true and B is true...." No serious formal proof system is based on diagrams.
This book explores the reasons why structured graphics have been largely ignored in contemporary formal theories of axiomatic systems. In particular, it elucidates the systematic forces in the intellectual history of mathematics which have driven the adoption of sentential representational styles over diagrammatic ones. In this book, the effects of historical forces on the evolution of diagrammatically-based systems of inference in logic and geometry are traced from antiquity to the early twentieth-century work of David Hilbert. From this exploration emerges an understanding that the present negative attitudes towards the use of diagrams in logic and geometry owe more to implicit appeals to their history and philosophical background than to any technical incompatibility with modern theories of logical systems.
