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 10th in the Transactions on Aspect-Oriented Software Development series, contains revised, extended versions of the top five papers presented at AOSD 2012. The topics covered include debugging, analysis of software product lines, distributed software architectures, and empirical study of language support for software evolution.

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.

This collection of top-notch articles by well-known experts brings together, for the first time, key elements of this area that are fast becoming the focus of much current research and practice in computing. About half the articles deal with theoretical frameworks, models, and systems of notation; the rest comprise case studies by architects of prototype systems who 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. An introduction by Clemens Szyperski gives a snapshot of current research in the field.

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 Sudholt, 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.

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.
