The book covers a wide range of topics related to system development, verification, and testing in software and hardware engineering. It discusses a system development process using Event-B and the Rodin platform, addressing challenges in software certification and the integration of formal methods with system management. Key topics include the formal engineering of access control policies, a verification framework for agent knowledge, and the transition from model-based design to formal verification of adaptive embedded systems. The text also explores machine-assisted proof support, tools for verifying component integration in composite timed systems, and approaches for integrating specification-based review with testing to detect program errors. Additionally, it examines methods for reducing test sequence lengths, model checking with SAT-based characterization, and automating refinement checking in probabilistic system design. Practical applications of model checking, including analysis of bootloaders, are also highlighted. In hardware, the book presents denotational semantics for hardware compilation, automatic generation of verified concurrent hardware, and modeling of clock synchronization using hybrid automata. Finally, it addresses concurrency through symbolic execution in process algebra and formalization of virtual processors in thread algebra. An erratum is included regarding software certification challenges.

Focusing on the practical aspects of animal cell culture, this book serves as a comprehensive guide for establishing and maintaining cell cultures in both laboratory and large-scale settings. It highlights the significance of this technique in biochemical and physiological studies, as well as its commercial applications in the pharmaceutical industry. With minimal prerequisites, it is accessible for undergraduates, graduates, and seasoned researchers looking to deepen their understanding of this essential laboratory skill.

The discovery of a cult horror movie from the 1970s leads Ben and his girlfriend, Lena, into a nightmarish experience as they find themselves ensnared in its unsettling universe. Joined by fellow victims Frank and Katherine, the group seeks a way to escape the film's sinister grip. Together, they embark on a quest for exorcism, blending elements of horror and camaraderie as they confront the chilling realities of the movie's influence on their lives.

A wide-ranging collection of essays by leading British, American and German scholars, covering German literature, culture and politics from the Middle Ages to the present day. Based mainly on original research, the individual contributions reveal the rich complexity and vitality of contemporary German studies.

This book constitutes the refereed proceedings of the 17th International Symposium on Formal Methods, FM 2011, held in Limerick, Ireland, in June 2011. The 29 revised full papers presented together with 3 invited talks were carefully reviewed and selected from numerous submissions. The papers are organized in topical sections on cyber-physical systems, runtime analysis, case studies/tools, experience, program compilation and transformation, security, progress algebra, education, concurrency, dynamic structures, and model checking.

The increasing complexity of modern software systems complicates the assurance of their dependability. Factors such as intricate operating environments, stringent dependability requirements, and complex infrastructures present significant engineering challenges in system design. Mastering this complexity necessitates design techniques that promote clear thinking alongside rigorous validation and verification, which can be achieved through formal design methods. Additionally, architectures must be resilient to faults and unpredictable environmental changes, necessitating fault-tolerant design techniques. This book addresses critical issues in developing fault-tolerant systems, including verification and refinement, integrated development approaches, formal foundations for error detection and recovery, and patterns for rigorous fault tolerance development. It also covers fault-tolerant software architectures, tools for supporting dependable system design, and integrated platforms for developing such systems. The editors participated in the EU (FP-6) project RODIN, which united researchers from the fault tolerance and formal methods communities. In 2007, RODIN organized the MeMoT workshop alongside the Integrated Formal Methods 2007 Conference at Oxford University, fostering collaboration and innovation in this vital area of research.

Many software systems have reached a level of complication, mainly because of their size, heterogeneity and distribution, which results in faults appearing that cannot be traced back easily to the code. Some of these „faults“ could also be unexpected program behavior that appears as a result of interactions between different parts of the program; this is commonly known as complexity. New methods, approaches, tools and techniques are needed to cope with the increasing complexity in software systems; amongst them, fault-tolerance techniques and formal methods, supported by the corresponding tools, are promising solutions. This book brings together papers focusing on the application of rigorous design techniques to the development of fault-tolerant, software-based systems. This volume is an outcome of the REFT 2005 Workshop on Rigorous Engineering of Fault-Tolerant Systems held in conjunction with the Formal Methods 2005 conference at Newcastle upon Tyne, UK, in July 2005. The authors of the best workshop papers were asked to enhance and expand their work and a number of well-established researchers working in the area contributed invited chapters. From the 19 refereed and revised papers presented, 12 are versions reworked from the workshop; 9 of them are totally new. The book is rounded off by two provocatively different position on the role of programming languages.

The third international conference on Integrated Formal Methods took place in Turku, Finland, from May 15–17, 2002, organized by Abo Akademi University and the Turku Centre for Computer Science. Building on previous themes, IFM 2002 aimed to further explore the integration of formal methods and notations, particularly focusing on the relationship between formal methods and graphical notations like the Unified Modeling Language (UML). This conference reflected a growing trend within the Formal Methods and Software Engineering research communities, highlighting the advancements made over the past three decades. Researchers have developed various formalisms that address specific aspects of behavior or analysis, including sequential and concurrent program structures, data and information structures, temporal reasoning, deductive proof, and model checking. A significant effort is now directed toward integrating these methods to leverage their advantages and meet industrial demands. Additionally, the increasing use of graphical notations in software engineering underscores the need for formal underpinnings and analysis capabilities that formal methods provide. This integration is essential for ensuring that formal methods can effectively scale to meet the needs of the industry.

This book is a comprehensive study of the narrative fiction of Heinrich Böll (1917–1985). Böll's first published stories date from 1947, and his was one of the first original voices to emerge from the physical and moral devastation left by the collapse of Hitler's Germany. Twenty-five years later he was awarded the Nobel Prize for Literature, and at his death in 1985 he was the best-known and most controversial writer of his generation. Attacked and admired in equal measure, he was widely acknowledged as the uncomfortable and uncompromising 'conscience of the nation'. This new study assesses Böll's creative achievement in the context of the society which helped to shape it, referring frequently to his essays, speeches and interviews where these throw light on his moral, aesthetic and political preoccupations. The analysis reveals the work of a conservative moralist and constantly embattled intellectual, who developed into a writer of European stature.
