As computer technology is used to control critical systems to an increasing degree, it is vital that the methods for developing and understanding these systems are substantially improved. The mathematical and scientific foundations currently used are extremely limited which means that their correctness and reliability cannot be ensured to an acceptable level. Systems engineering needs to become a fully fledged scientific discipline and formal methods, which are characterised by their firm mathematical foundations, are playing a vital role in achieving this transition. This volume is based on the proceedings of the Formal Methods Workshop (FM91), held in Drymen, Scotland, 24-27 September 1991. This was the second workshop sponsored by the Canadian and US governments to address the role of formal methods in the development of digital systems. Traditionally, formal methods have evolved in isolation from more conventional approaches, and one of the aims of this workshop was to emphasise the benefits of integrating the two areas. The workshop concentrated on the themes of quality assurance, design methods and mathematical modelling techniques. Particular emphasis was given to safety and security applications. Among the topics covered in this volume are: what is a formal method?; social research on formal methods; current quality assurance methods and formal methods; a pragmatic approach to validation; integrating methods in practice; composition of descriptions; and topics in large program formal development. Formal Methods in Systems Engineering provides an overview of many of the major approaches to formal methods and the benefits which can result from them. It is relevant to academic and industrial researchers, industrial practitioners and government workers with an interest in certification.

As a consequence of the wide distribution of software and software infrastructure, information security and safety depend on the quality and excellent understanding of its functioning. Only if this functionality is guaranteed as safe, customer and information are protected against adversarial attacks and malfunction. A vast proportion of information exchange is dominated by computer systems. Due to the fact that technical systems are more or less interfaced with software systems, most information exchange is closely related to software and computer systems. Information safety and security of software systems depend on the quality and excellent understanding of its functioning. The last few years have shown a renewed interest in formally specifying and verifying software and its role in engineering methods. Within the last decade, interactive program verifiers have been applied to control software and other critical applications. Software model checking has made strides into industrial applications and a number of research tools for bug detection have been built using automatic program-verification technology. Such solutions are high-level programming methods which provide strategies to ensure information security in complex software systems by automatically verified correctness. Based on the specific needs in applications of software technology, models and formal methods must serve the needs and the quality of advanced software engineering methods. This book provides an in-depth presentation of state-of-the-art topics on how to meet such challenges covering both theoretical foundations and industrial practice.

Software-intensive systems are today an integral part of many everyday products. Whilst they provide great benefits regarding ease of use and allow for new applications, they also impose enormous responsibilities. It is vital to ensure that such applicati

Smart grid is a new generation of power grids that is expected to enhance its reliability and reduce carbon footprint by integrating distributed resources. Microgrid technology allows the integration of renewable energies, which come in three modes: AC, DC, or hybrid. The increasing number of DC loads, the need to reduce power loss in converting DC power to AC, and the existence of DC storage units have favored the adoption of DC microgrids. The electrification of the transportation sector has further supported the adoption of DC microgrids. A DC microgrid system comprises renewable resources, DC storage elements, DC loads, and intelligent electrical devices. It has gained interest due to its efficiency, scalability, and cost-effectiveness. DC microgrids play a crucial role in powering diverse applications such as data centers, residential areas, base stations, and electric vehicle charging stations. This book covers the design, control, and management of DC microgrids in both islanded and grid-connected modes. It focuses on ICT infrastructure, security, sensors, embedded systems, machine learning algorithms, edge/fog computing, and the socio-economic impact.

This book covers various aspects of security, privacy and reliability in Internet of Things (IoT) and Cyber-Physical System design, analysis and testing. In particular, various established theories and practices both from academia and industry are presented and suitably organized targeting students, engineers and researchers. Fifteen leading academicians and practitioners wrote this book, pointing to the open problems and biggest challenges on which research in the near future will be focused.
