By Maarten Marx (auth.), Luke Ong (eds.)

This e-book constitutes the refereed lawsuits of the nineteenth overseas Workshop on computing device technological know-how common sense, CSL 2005, held because the 14th Annual convention of the EACSL in Oxford, united kingdom in August 2005.

The 33 revised complete papers awarded including four invited contributions have been rigorously reviewed and chosen from 108 papers submitted. All present facets of good judgment in desktop technological know-how are addressed starting from mathematical good judgment and logical foundations to methodological concerns and purposes of logics in a number of computing contexts. the quantity is equipped in topical sections on semantics and logics, sort conception and lambda calculus, linear good judgment and ludics, constraints, finite types, decidability and complexity, verification and version checking, confident reasoning and computational arithmetic, and implicit computational complexity and rewriting.

Periodic Tales: A Cultural History of the Elements, from Arsenic to Zinc

just like the alphabet, the calendar, or the zodiac, the periodic desk of the chemical parts has an enduring position in our mind's eye. yet other than the handful of universal ones (iron, carbon, copper, gold), the weather themselves stay wrapped in secret. we don't be aware of what such a lot of them seem like, how they exist in nature, how they received their names, or of what use they're to us. Unlocking their impressive secrets and techniques and colourful pasts, Periodic stories is a passionate trip via mines and artists’ studios, to factories and cathedrals, into the woods and to the ocean to find the real tales of those interesting yet mysterious development blocks of the universe.

The Lady Anatomist: The Life and Work of Anna Morandi Manzolini

Anna Morandi Manzolini (1714-74), a lady artist and scientist, surmounted meager origins and constrained formal schooling to turn into the most acclaimed anatomical sculptors of the Enlightenment. the woman Anatomist tells the tale of her arresting existence and occasions, in gentle of the intertwined histories of technological know-how, gender, and artwork that complex her upward thrust to status within the eighteenth century.

We prove a strong normalization theorem for abstract term rewriting systems based on domain-theoretic models.

We discuss connections to work on type systems for memory-management, specifically alias types [18] and regions [17], [19], where the use of location and region variables leads to forms of polymorphism. For alias types, this polymorphism appears to be multiplicative. The work reported herein was carried out under the project ‘Bunched ML’, funded by the United Kingdom EPSRC. We acknowledge help and suggestions given by our collaborators, Josh Berdine and Peter O’Hearn of Queen Mary University London.

Prove that all constants are total. Note that the proof-theoretic strength necessary to prove termination for a particular rewrite system goes entirely into the proof of totality. Therefore one can say that our method reduces termination proofs to (technically much simpler) totality proofs. g. in [6, 16, 18]. In addition, the method not only simplifies existing proofs, but also leads to new results, such as the strong normalization proof for open recursion presented here. Since our normalization results for higher-order rewrite systems depend on a given proof of strong normalization for the underlying typed λ-calculus our method does not compete with generic approaches to strong normalization for type theories [19, 20].
