This book constitutes the refereed proceedings of the 15th European Symposium on Programming, ESOP 2006, held in Vienna, Austria in March 2006 as part of ETAPS.

The 21 revised full papers presented together with 2 invited talks were carefully reviewed and selected from 87 submissions. The papers address fundamental issues in the specification, analysis, and implementation of programming languages and systems; they are organized in topical sections on types for implementations, proof and types, verification and reasoning, security and distribution, analysis and verification, and...

The bicycle ranks as one of the most enduring, most widely used vehicles in the world, with more than a billion produced during almost two hundred years of cycling history. This book offers an authoritative and comprehensive account of the bicycle's technical and historical evolution, from the earliest velocipedes (invented to fill the need for horseless transport during a shortage of oats) to modern racing bikes, mountain bikes, and recumbents. It traces the bicycle's development in terms of materials, ergonomics, and vehicle physics, as carried out by inventors, entrepreneurs, and...

This book uses a functional programming language (F#) as a metalanguage to present all concepts and examples, and thus has an operational flavour, enabling practical experiments and exercises. It includes basic concepts such as abstract syntax, interpretation, stack machines, compilation, type checking, garbage collection, and real machine code. Also included are more advanced topics on polymorphic types, type inference using unification, co- and contravariant types, continuations, and backwards code generation with on-the-fly peephole optimization.
