The IJCAR conference series is aimed at unifying the di?erent research principles within automated reasoning. IJCAR 2008 was the fusion of several major international events: -CADE: The International Conference on Automated Deduction -FroCoS: The Symposium on Frontiers of Combining Systems -FTP: The Workshop on First-Order Theorem Proving - TABLEAUX: The Conference on Analytic Tableaux and Related Methods Previous versions of IJCAR were held in Seattle (USA) in 2006, Cork (Ireland) in 2004, and Siena (Italy) in 2001. These proceedings comprise 4 contributions by invited speakers, 26 research papers, and 13 system descriptions. The volume also includes a short overview of the CASC-J4 competition for automated theorem proving systems that was conductedduringIJCAR2008.TheinvitedspeakerswereHubertComon-Lundh, NachumDershowitz, AartiGupta, andCarstenLutz.Theirtalkscoveredabroad spectrum of automated reasoning themes, viz., veri?cation of security protocols, prooftheoreticalframeworksfor ?rst-orderlogic, automateddecisionprocedures and software veri?cation, and description logics. The contributed papers were selected from 80 research paper submissions and 17 system description submissions. Each submission was reviewed by at least three reviewers, and decisions were reached after two weeks of discussion through an electronic Program Committee meeting. The submissions, reviews, and discussion were coordinated using the EasyChair conference management system. The accepted papers spanned a wide spectrum of researchin automated reasoning, including saturation, equationalreasoninganduni?cation, automa- based methods, description logics and related logics, sati?ability modulo theory, decidable logics, reasoning about programs, and higher-order l

This book constitutes the refereed proceedings of the 4th International Conference on Frontiers of Combining Systems, FroCoS 2002, held in Santa Margherita Ligure, Italy, in April 2002.The 14 revised full papers presented together with 3 invited papers were carefully reviewed and selected from 35 submissions. Among the topics covered are combination of logics, combination of constraint solving techniques, combination of decision procedures, combination problems in verification, modular problems of theorem proving, and the integration of decision procedures and other solving processes into constraint programming and deduction systems.

This book is an experiment on constructing a text starting — exclusively and strictly — from the materials of an architectural project. As in an archive, it contains all the documents produced by the design team, which become the only sources of a text that allows the reader to generalise the project’s contents and reflect on its process. An extensive masterplan is transforming the abandoned industrial area of Shougang, on the outskirts of Beijing, into one of the venues for the 2022 Winter Olympics Games. Within this process, the China Room, as a research centre of the Politecnico di Torino dedicated to urbanisation and architecture in China, was involved by Tsinghua University in the transformation of the former oxygen factory into a visitor centre, working on industrial memory as a lever for a renovation of the existing aimed at the overall sustainability of the masterplan. The book overviews and analyses the most important steps that transformed initial design intentions into a defined proposal, passing through different solutions, changes, debates, and negotiations among the different stakeholders called into action along the whole process. Telling the story of this architectural project means thinking about the ways of designing across different contexts in the global market. More particularly, the story is about the skills and experiences that Academia puts in place by addressing real transformation projects through research, with respect to professional practice modalities. In addition, the book is intended to make design practicing transparent to the reader, capable to move around the genesis of the project following the many trajectories occurred along the whole process, similarly to an open archive: retrospectively the final image of the building will incorporate architectural elements brought by socio-technical decisions, enlarging the spectrum of design agency from single authorship to a larger collective of involved stakeholders. Among the project documents, a recurring drawing guided the project exchange between the Politecnico and Tsinghua teams during the two years of joint design work. The cross-section of the factory was the point of comparison about the relationship with the structural skeleton of the original factory and the vertical organisation of the project: from the public playground on the ground floor to the intensive exploitation of the intermediate levels, to the roof that seeks new relationships with the competition area and the natural landscape.
