This collection of articles by well-known experts was originally published in 2000 and is intended for researchers in computer science, practitioners of formal methods, and computer programmers working in safety-critical applications or in the technology of component-based systems. The work brings together several elements of this area that were fast becoming the focus of much research and practice in computing. The introduction by Clemens Szyperski gives a snapshot of research in the field. About half the articles deal with theoretical frameworks, models, and systems of notation; the rest of the book concentrates on case studies by researchers who have built prototype systems and present findings on architectures verification. The emphasis is on advances in the technological infrastructure of component-based systems; how to design and specify reusable components; and how to reason about, verify, and validate systems from components. Thus the book shows how theory might move into practice.

The LNCS Transactions on Modularity and Composition are devoted to all aspects of software modularity and composition methods, tools, and techniques, covering requirement analysis, design, implementation, maintenance, and evolution. The focus of the journal also includes modelling techniques, new paradigms and languages, development tools, measurement, novel verification and testing approaches, theoretical foundations, and understanding interactions between modularity and composition.This, the first issue of the Transactions on Modularity and Composition, consists of two sections. The first one, guest edited by Patrick Eugster, Mario Südholt, and Lukasz Ziarek, is entitled “Aspects, Events, and Modularity” and includes papers focusing on context-oriented software development, specifications for even-based systems, and development of modular software. The second section, guest edited by Gary T. Leavens, contains journal versions of selected papers from Modularity 2015, which was held in March 2015, in Fort Collins, Colorado, USA. Topics covered by the papers in this section include software unbundling, layer activation in context-oriented programming, modular reasoning in event-based languages, and dynamic dispatch for method contracts using abstract predicates.The paper 'Dynamic Dispatch for Method Contracts Through Abstract Predicates' is published open access under a CC BY 4.0 license at link.springer.com.

Veri?ed Software: Theories, Tools and Experiments, VSTTE 2010, was held in Edinburgh, Scotland during August 16-19, 2010. This conference is part of the Veri?ed Software Initiative (VSI), which is a 15-year international project that focuses on the scienti?c and technical challenges of producing veri?ed software. Previous VSTTE conferences were held in Zurich, Switzerland (in 2005) and Toronto, Canada (in 2008). The goal of VSTTE 2010 was to advance the state of the art in the science andtechnologyofsoftwareveri?cationthroughtheinteractionoftheorydevel- ment,toolevolution,andexperimentalvalidation.Theacceptedpapersrepresent work on veri?cation techniques, speci?cation languages, formal calculi, veri?- tion tools, solutions to challenge problems, software design methods, reusable components, re?nement methodologies, and requirements modeling. Several of the accepted papers also presented case studies, either in response to published challenge problems or problems of practical interest. Many of the papers were also concerned with concurrent programs.

This system aided the Program Committee in avoiding con?icts of interest during the reviewing and discussion process. There was electronic discussion among the Program Committee m- bersaboutthemeritsofeachsubmission,moderatedbytheProgramCommittee Co-chairs. This year the conference received 32 submissions, of which 11 were accepted, for an acceptance rate of about 34%. Seven of the accepted papers were - authored by members of the Program Committee. We were pleased to have invited talks by Tom Ball, Gerwin Klein, and Matthew Parkinson.The authorsof these invitedtalks also graciouslyconsented to the publication of accompanying invited papers in this volume.

The LNCS journal Transactions on Aspect-Oriented Software Development is devoted to all facets of aspect-oriented software development (AOSD) techniques in the context of all phases of the software life cycle, from requirements and design to implementation, maintenance and evolution. The focus of the journal is on approaches for systematic identification, modularization, representation and composition of crosscutting concerns, i.e., the aspects and evaluation of such approaches and their impact on improving quality attributes of software systems.This volume, the 9th in the Transactions on Aspect-Oriented Software Development series, contains three regular submissions and two special sections, each consisting of two papers. The papers focus on the following topics: modularization, pointcut language, dynamic adaptation, event-based programming, aspect-aware design, system software, object composition and templates.
