“…ALDEBARAN, together with companion tools of CADP, has been used in numerous case studies 4 by scientists of many universities worldwide. Among the case studies involving equivalence checking, one can mention, in chronological order: a car overtaking protocol [142], dynamically changing communication structures [166], an ATM switch [157], a plain ordinary telephone service (starting from an existing specification [144]), a framework for groupware development [272], a trusted third-party protocol between video-on-demand service providers and customers [299] [183], a railway signalling system [164], a bounded retransmission protocol [323] [324] (starting from an existing specification [203]), the TCP Internet transport protocol [379], feature interactions in telephony systems [277], several variants of distributed leader election algorithms for unidirectional ring networks [181], a bus arbiter of a multiprocessor architecture [86], the link layer protocol of the IEEE-1394 serial bus [381], a departure clearance protocol for air traffic [121], testing of a distributed leader election algorithm [397] [396], a flow-control protocol for a high-speed network [222], patterns for software architecture styles [216], an invoicing system [380] [382], a protocol for road traffic control [424] [423], asynchronous circuits [431] [432] [433], a reliable data-transfer service [312], an abstraction-display-controller model for user interfaces [321], a distributed cluster file system [358] [359], an ISO high-speed transport protocol [25], highly reliable and reusable CORBA applications [279], a leader election protocol for home audio/video networks [367], synchronous hardware [215] [214] [213], a protocol for deploying intelligent telecommunication services [14]…”

Equivalence checking is a formal verification approach that consists in proving that two programs or models are related modulo some equivalence relation, or that one is included in the other modulo some preorder relation. In the case of concurrent systems, which are often represented using labelled transition systems, the relations used for equivalence checking are bisimulations and their simulation preorders. In the case of probabilistic or stochastic systems, which are usually represented using Markov chains, the relations used for equivalence checking are lumpability, probabilistic and stochastic equivalences, and their associated preorders. The present article provides a synthetic overview of 40 years of research in the design of algorithms and software tools for equivalence checking.

“…At first sight, these two approaches may look simpler and more elegant than the one of Graf & Steffen, because they do not require a semi-composition operator, but they are actually inferior (although they were published later than [36]), for at least three reasons: 46 Internal actions are usually noted τ in most process calculi. 47 This state is called cut state in [81].…”

Concurrent systems are intrinsically complex and their verification is hampered by the well-known "state-space explosion" issue. Compositional verification is a powerful approach, based on the divide-and-conquer paradigm, to address this issue. Despite impressive results, this approach is not used widely enough in practice, probably because it exists under multiple variants that make knowledge of the field hard to attain. In this article, we highlight the seminal results of Graf & Steffen and propose a survey of compositional verification techniques that exploit (or not) these results.

“…Some frameworks have been proposed to support the development of groupware (COSQUER et al, 2000;GREENBERG, 1991b;KERBRAT;ATALLAH, 1995;SAGE, 2001;SCHOEBERLEIN;. These frameworks focus on system architecture aspects to design groupware.…”

During the last decades, the research field of Computer-Supported Collaborative Work has made impressive progress in proposing theories, techniques, and tools to support collaborative work in different settings. Nevertheless, despite the advances in the field and its branches, individuals with impairments still face inclusion challenges when performing computer-supported collaborative activities. In order to take part in such type of activities, individuals are expected to have skills and knowledge that may be affected by impairments. In the beginning of this PhD research, we studied means to include an individual with blindness in diagram-based activities conducted as part of software engineering lectures taught by the thesis author. As part of that, we noticed that researchers and practitioners generally did not follow any collaboration-oriented method to address accessibility issues when designing or redesigning collaboration supportive systems, also known as groupware. In this context, we decided to focus our attention on this gap. As a result, we developed Collab4All, a method to support the identification of potential challenges as well as alternative solutions that may arise when designing or redesigning accessible and inclusive groupware. As a proof of concept, we applied Collab4All to the aforementioned scenario of including individuals with blindness in diagram-related learning activities. Based on our findings, we documented some suggestions to researchers and developers working in this application scenario. The present document contains detailed information about this research process. We consider that the method proposed in this thesis, its application results and the groupware we developed, named Model2gether, are relevant contributions to the field of computer-supported collaborative work involving people with impairments.
