Book Description
Validation of Communications Systems with SDL provides a clear practical guide to validating, by simulation, a telecom system modelled in SDL. SDL, the Specification and Description Language standardised by the International Telecommunication Union (ITU-T), is used to specify and develop complex systems such as GSM, GPRS, UMTS, IEEE 802.11 or Hiperlan. Since the downturn in the telecom industry, validating a system before its implementation has become mandatory to reduce costs. This volume guides you step by step through the validation of a simplified protocol layer, from interactive simulation to proof of properties using reachability analysis combined with observers. Every step is explained, using the two main SDL tools commercially available: ObjectGeodeTM and Tau SDLTM Suite, both from Telelogic. Contents: Short tutorial on SDL Presentation of the protocol layer case study Interactive simulation, MSC generation Scripting, automatic non-regression Auto matic validation against MSC, HMSC, etc. Random simulation Exhaustive and bit-state simulation Errors detected and not detected by simulation Other simulator features This book offers you the opportunity to: Learn expert validation techniques and tips Master advanced simulation features of Telelogic ObjectGeodeTM and Tau SDL SuiteTM Practice 156 hands-on exercises with solutions. The SDL models and scripts used in the exercises can be downloaded from the Web.

Book Description
This volume contains the papers presented at the 12th SDL Forum, Grimstad, Norway. The SDL Forum was ?rst held in 1982, and then every two years from 1985. Initially the Forum was concerned only with the Speci?cation and Description Language that was ?rst standardized in the 1976 Orange Book of the Inter- tional Telecommunication Union (ITU). Since then, many developments took place and the language has undergone several changes. However, the main underlying paradigm has survived, and it is the reason for the success of the Speci?cation and Description Language in many projects. This paradigm is based on the following important principles of distributed - plications: Communication: large systems tend to be described using smaller parts that communicate with each other; State: the systems are described on the basis of an explicit notion of state; State change: the behavior of the system is described in terms of (local) changes of the state. The original language is not the only representative for this kind of paradigm, so the scope of the SDL Forum was extended quite soon after the ?rst few events to also include other ITU standardized languages of the same family, such as MSC, ASN.1 and TTCN. This led to the current scope of System Design Languages coveringallstagesofthedevelopmentprocessincludinginparticularSDL,MSC, UML, ASN.1, eODL, TTCN, and URN. The focus is clearly on the advantages to users, and how to get from these languages the same advantage given by the ITU Speci?cation and Description Language: code generation from high-level speci?cations.

Book Description
This book constitutes the refereed proceedings of the 11th International Conference on System Analysis and Modeling, SAM 2019, held in Munich, Germany, in September 2019. The 12 full papers and 2 work in progress papers presented together with one keynote talk were carefully reviewed and selected from 28 submissions. The papers discuss the most recent innovations, trends, and experiences in modeling and analysis of complex systems using ITU-T's Specification and Description Language (SDL-2010) and Message Sequence Chart (MSC) notations, as well as related system design languages — including UML, ASN.1, TTCN, SysML, and the User Requirements Notation (URN). SAM 2019’s theme was “Languages, Methods, and Tools for Industry 4.0.”

Book Description
Models and simulations are an important first step in developing computer applications to solve real-world problems. However, in order to be truly effective, computer programmers must use formal modeling languages to evaluate these simulations. Formal Languages for Computer Simulation: Transdisciplinary Models and Applications investigates a variety of programming languages used in validating and verifying models in order to assist in their eventual implementation. This book will explore different methods of evaluating and formalizing simulation models, enabling computer and industrial engineers, mathematicians, and students working with computer simulations to thoroughly understand the progression from simulation to product, improving the overall effectiveness of modeling systems.

Book Description
This book provides comprehensive coverage of the protocols of communication systems. The book is divided into four parts. Part I covers the basic concepts of system and protocol design and specification, overviews the models and languages for informal and formal specification of protocols, and describes the specification language SDL. In the second part, the basic notions and properties of communication protocols and protocol stacks are explained, including the treatment of the logical correctness and the performance of protocols. In the third part, many methods for message transfer, on which specific communication protocols are based, are explained and formally specified in the SDL language. The fourth part provides for short descriptions of some specific protocols, mainly used in IP networks, in order to acquaint a reader with the practical use of communication methods presented in the third part of the book. The book is relevant to researchers, academics, professionals and students in communications engineering. Provides comprehensive yet granular coverage of the protocols of communication systems Allows readers the ability to understand the formal specification of communication protocols Specifies communication methods and protocols in the specification language SDL, giving readers practical tools to venture on their own

Book Description
The focus of this book is original research regarding the implementation of problem-based learning and pedagogies of play as active approaches to foster self-directed learning. With the Fourth Industrial Revolution (4IR) in mind, educational institutions need to rethink teaching and learning for the future. As such, active engagement can be encouraged, as evident in this book, where problem-based learning drives learning through real-world problems, while pedagogy of play focuses on innovative environments where the action of play and learning are integrated with the aim of developing SDL. The following are addressed in the chapters: an overview of problem-based learning and pedagogy of play, metaliteracy, playful problem-based learning tasks, computational thinking in game-based tasks and geometry, solving puzzles, applying LEGO®, using drama as the pedagogy of play and implementing educational robotics. The empirical research findings disseminated in this book aim to inspire academics in the research focus area of self-directed learning with active learning approaches in the school and tertiary classroom that hold affordances to enhance 21st-century skills. Active learning is an umbrella term for pedagogies that mainstream student engagement, such as problem-based learning, cooperative learning, gamification, role-play and drama. This scholarly book highlights various engaging pedagogies.
