Logic programming synthesis and transformation are methods are deriving logic programs from their specifications and, where necessary, producing alternative but equivalent forms of a given program. The techniques involved in synthesis and transformation are extremely important as they allow the systematic construction of correct and efficient programs and have the potential to enhance current methods of software production. Transformation strategies are also being widely used in the field of logic program development. LOPSTR 91 was the first workshop to deal exclusively with both logic program synthesis and transformation and, as such, filled an obvious gap in the existing range of logic programming workshops. In attempting to cover the subject as comprehensively as possible, the workshop brought together researchers with an interest in all aspects of logic (including Horn Clause and first order logic) and all approaches to program synthesis and transformation. "Logic Program Synthesis and Transformation" provides a complete record of the workshop, with all the papers re-produced either in full or as extended abstracts.They cover a wide range of aspects, both practical and theoretical, including the use of mode input-output in program transformation, program specification and synthesis in constructive formal systems and a case study in formal program development in modular Prolog. This volume provides a comprehensive overview of current research and will be invaluable to researchers and postgraduate students who wish to enhance their understanding of logic programming techniques.

Logic programme synthesis and transformation are topics of central importance to the software industry. The demand for software cannot be met by the current supply, in terms of volume, complexity or reliability. The most promising solution seems to be the increased automation of software production, as programmer productivity would improve, and correctness could be ensured by the application of mathematical methods. Because of their mathematical foundations, logic programmes lend themselves particularly well to machine-assisted development techniques, and therefore to automation. This volume contains the proceedings of the 2nd International Workshop on Logic Programme Synthesis and Transformation (LOPSTR '92), held at the University of Manchester, July 1992. The LOPSTR workshops are the only international meetings devoted to these two important areas. A variety of new techniques were described at the workshop, all of which promise to revolutionize the software industry once they become standard practice.These include techniques for the transformation of an inefficient programme into an equivalent, efficient one, and the synthesis of a programme from a formal specification of its required behaviour. Among the topics covered in this volume are: optimal transformation of logic programmes; logic programme synthesis via proof planning; deductive synthesis of programmes for query answering; efficient compilation of lazy narrowing into PROLOG; synthesis of narrowing programmes; Logimix - a self-applicable partial evaluator for PROLOG; proof nets; and automatic termination analysis.

This book presents a unique state-of-the-art survey on progress in the field of program development making use of computational logic. The motivating idea behind this approach is the belief that declarative paradigms such as logic programming are better suited to program development tasks than traditional non-declarative ones such as imperative paradigms. Closely related to the international workshop and symposium series "Logic Program Synthesis and Transformation", later renamed "Program Development in Computational Logic", this book presents 15 carefully selected and reviewed articles and surveys by leading researchers in the area. The contributions are grouped in sections on specification and synthesis, semantics, analysis, transformation and specialization, termination, and systems.

This volume contains papers presented at the 7th International Conference on Formal Engineering Methods (ICFEM 2005), 1-4 November 2005, Manchester, UK. Formal engineering methods are changing the way that systems are dev- oped. With language and tool support, these methods are being used for se- automatic code generation, and for the automatic abstraction and checking of implementations. In the future, they will be used at every stage of development: requirements,speci?cation,design,implementation,testing,anddocumentation. The aim of ICFEM 2005 was to bring together those interested in the - plication of formal engineering methods to computer systems. Researchers and practitioners, from industry, academia, and government, were encouraged to - tend, and to help advance the state of the art. The conference was supported by sponsorships from Microsoft Research, USA, the Software Engineers Association of Japan, the University of Man- ester, Manchester City Council, FormalMethods Europe (FME) and the British Computer Society FormalAspects ofComputing Specialist Group(BCS-FACS). We wish to thank these sponsors for their generosity. The ?nal programme consisted of 3 invited talks and 30 technical papers selected from a total of 74 submissions.The invited speakers were: Anthony Hall, independent consultant, UK; Egon B.. orger, University of Pisa, Italy; John Rushby, SRI, USA. Their talks were sponsored by BCS-FACS, Microsoft - search and FME respectively. We wish to thank the invited speakers for their inspiring talks.

This book constitutes the refereed proceedings of the First International Conference on Computational Logic, CL 2000, held in London, UK in July 2000. The 86 revised full papers presented together with five invited papers were carefully reviewed and selected from a total of 176 submissions. In accordance with the seven streams, the papers are organized in sections on program development, logic programming - theory and extensions, constraints, automated deduction - putting theory into practice, knowledge representation and nonmonotonic reasoning, database systems, and logic programming - implementations and applications.

This book constitutes the refereed proceedings of the Second European Conference on Service-Oriented and Cloud Computing, ESOCC 2013, held in Málaga, Spain, in September 2013. The 11 full papers presented together with 4 short papers were carefully reviewed and selected from 44 submissions. The volume also contains 3 papers from the industrial track. Service-oriented computing including Web services as its most important implementation platform has become the most important paradigm for distributed software development and application. The papers illustrate how cloud computing aims at enabling mobility as well as device, platform and/or service independence by offering centralized sharing of resources. It promotes interoperability, portability and security standards, and raises a completely new set of security issues.

The papers are organized in topical sections on cloud technology, service composition, software development and cloud technology, cloud computing, industry track.

The book provides a comprehensive coverage of the widely accepted desiderata of component-based software development, as well as the foundations that these desiderata necessitate. Its unique focus is on component models, the cornerstone of component-based software development. In addition, it presents and analyses existing approaches according to these desiderata.This compendium is an indispensable textbook for an advance undergraduate or postgraduate course unit. Researchers will also find this volume an essential reference material.
