This tutorial book presents an augmented selection of the material presented at the First Pernambuco Summer School on Software Engineering, PSSE 2004, held in Receife, Brazil in November/December 2004, jointly with the Brazilian Symposium on Formal Methods (SBMF 2004).

The 7 tutorial lectures presented are the thoroughly revised versions of the contributions from the invited lecturers. The revision was inspired by the synergy generated by the opportunity for the lecturers to present and discuss their work among themselves, and with the school's attendees. The courses cover a wide spectrum of topics in software engineering such as concurrency, probability, real time, model checking, and object orientation. Apart from languages and techniques, the courses also cover the semantic underpinnings of refinement, and industrial applications and refinement tools.

This volume contains papers presented at UTP 2019, the 7th International Symposium on Unifying Theories of Programming, held in Porto, Portugal, on the 8th of October 2019. This edition of the UTP symposium is in honor of Sir Tony Hoare, on the occasion of his 85th birthday. The papers contained in this volume were invited, and friendly refereed, original contributions sought from the UTP community. One of the papers is from the distinguished invited speaker Tony Hoare himself. Nine other additional papers compose this volume, covering several aspects of Unifying Theories of Programming.

This book constitutes the refereed proceedings of the 13th International Colloquium on Theoretical Aspects of Computing, ICTAC 2016, held in Taipei, Taiwan, in October 2016. The 23 revised full papers presented together with two short papers, two invited papers and one abstract of an invited paper were carefully reviewed and selected from 60 submissions. The papers are organized in topical sections on program verification; design, synthesis and testing; calculi; specifications; composition and transformation; automata; temporal logics; tool and short papers.
