The book constitutes the refereed proceedings of the 12th International Conference on Software Composition, SC 2013, held in Budapest, Hungary, in June 2013, co-located with the STAF 2013 Federated Conferences. The 9 revised full papers were carefully reviewed and selected from 21 submissions for inclusion in the book. The papers reflect all current research in software composition, including but not limited to component-based software engineering; composition and adaption techniques; composition algebras, calculi, and type systems; feature-oriented software development; verification, validation, and testing; dynamic composition and reconfiguration.

This book constitutes the thoroughly refereed post-proceedings of the 5th International Workshop on Software Composition, SC 2006, a satellite event of the European Joint Conferences on Theory and Practice of Software, ETAPS 2006. The book presents 21 revised full papers reflecting current research in software composition to foster development of composition models and techniques by using aspect-oriented programming, specification of component contracts and protocols, and methods of correct components composition.

This book constitutes the refereed proceedings of the 15th International Conference on Software Architecture, ECSA 2021, held in Sweden, in September 2021. Due to the COVID-19 pandemic, the conference was held virtually. For the Research Track, 11 full papers, presented together with 5 short papers, were carefully reviewed and selected from 58 submissions. The papers are organized in topical sections as follows: architectures for reconfigurable and self-adaptive systems; machine learning for software architecture; architectural knowledge, decisions, and rationale; architecting for quality attributes; architecture-centric source code analysis; and experiences and learnings from industrial case studies.
