This volume contains the papers presented. at the Third IFIP International Working Conference on Dependable Computing for Critical Applications, sponsored by IFIP Working Group 10.4 and held in Mondello (Sicily), Italy on September 14-16, 1992. System developers increasingly apply computers where they can affect the safety and security of people and equipment. The Third IFIP International Working Conference on Dependable Computing for Critical Applications, like its predecessors, addressed various aspects of computer system dependability, a broad term defined as the degree of trust that may justifiably be placed in a system's reliability, availability, safety, security, and performance. Because the scope of the conference was so broad, we hope the presentations and discussions will contribute to the integration of these concepts so that future computer-based systems will indeed be more dependable. The Program Committee selected 18 papers for presentation from a total of 7 4 submissions at a May meeting in Newcastle upon Tyne, UK. The resulting program represented a broad spectrum of interests, with papers from universities, corporations, and government agencies in eight countries. Much diligent work by the Program Committee and the quality of reviews from more than a hundred external referees from around the world, for which we are most grateful, significantly eased the production of this technical program.

According to the three covered conferences KDIR 2010, KEOD 2010, and KMIS 2010, the papers are organized in topical sections on knowledge discovery and information retrieval, knowledge engineering and ontology development, and on knowledge management and information sharing.

At the beginning of the 1990s research started in how to combine soft comput ing with reconfigurable hardware in a quite unique way. One of the methods that was developed has been called evolvable hardware. Thanks to evolution ary algorithms researchers have started to evolve electronic circuits routinely. A number of interesting circuits - with features unreachable by means of con ventional techniques - have been developed. Evolvable hardware is quite pop ular right now; more than fifty research groups are spread out over the world. Evolvable hardware has become a part of the curriculum at some universi ties. Evolvable hardware is being commercialized and there are specialized conferences devoted to evolvable hardware. On the other hand, surprisingly, we can feel the lack of a theoretical background and consistent design methodology in the area. Furthermore, it is quite difficult to implement really innovative and practically successful evolvable systems using contemporary digital reconfigurable technology."

Real-time computing systems are vital to a wide range of applications. For example, they are used in the control of nuclear reactors and automated manufacturing facilities, in controlling and tracking air traffic, and in communication systems. In recent years, real-time systems have also grown larger and become more critical. For instance, advanced aircraft such as the space shuttle must depend heavily on computer sys tems Carlow 84]. The centralized control of manufacturing facilities and assembly plants operated by robots are other examples at the heart of which lie embedded real-time systems. Military defense systems deployed in the air, on the ocean surface, land and underwater, have also been increasingly relying upon real-time systems for monitoring and operational safety purposes, and for retaliatory and containment measures. In telecommunications and in multi-media applications, real time characteristics are essential to maintain the integrity of transmitted data, audio and video signals. Many of these systems control, monitor or perform critical operations, and must respond quickly to emergency events in a wide range of embedded applications. They are therefore required to process tasks with stringent timing requirements and must perform these tasks in a way that these timing requirements are guaranteed to be met. Real-time scheduling al gorithms attempt to ensure that system timing behavior meets its specifications, but typically assume that tasks do not share logical or physical resources. Since resource-sharing cannot be eliminated, synchronization primitives must be used to ensure that resource consis tency constraints are not violated."

Research into grid computing has been driven by the need to solve large-scale, increasingly complex problems for scientific applications. Yet the applications of grid computing for business and casual users did not begin to emerge until the development of the concept of cloud computing, fueled by advances in virtualization techniques, coupled with the increased availability of ever-greater Internet bandwidth. The appeal of this new paradigm is mainly based on its simplicity, and the affordable price for seamless access to both computational and storage resources. This timely text/reference introduces the fundamental principles and techniques underlying grids, clouds and virtualization technologies, as well as reviewing the latest research and expected future developments in the field. Readers are guided through the key topics by internationally recognized experts, enabling them to develop their understanding of an area likely to play an ever more significant role in coming years. Topics and features: presents contributions from an international selection of experts in the field; provides a thorough introduction and overview of existing technologies in grids, clouds and virtualization, including a brief history of the field; examines the basic requirements for performance isolation of virtual machines on multi-core servers, analyzing a selection of system virtualization technologies; examines both business and scientific applications of grids and clouds, including their use in the life sciences and for high-performance computing; explores cloud building technologies, architectures for enhancing grid infrastructures with cloud computing, and cloud performance; discusses energy aware grids and clouds, workflows on grids and clouds, and cloud and grid programming models. This useful text will enable interested readers to familiarize themselves with the key topics of grids, clouds and virtualization, and to contribute to new advances in the field. Researchers, undergraduate and graduate students, system designers and programmers, and IT policy makers will all benefit from the material covered.

The process of designing large real-time embedded signal processing systems is plagued by a lack of coherent specification and design methodology. A canonical waterfall design process is commonly used to specify, design, and implement these systems with commercial-off-the-shelf (COTS) multiprocessing (MP) hardware and software. Powerful frameworks exist for each individual phase of this canonical design process, but no single methodology exists which enables these frameworks to work together coherently, i.e., allowing the output of a framework used in one phase to be consumed by a different framework used in the next phase. This lack of coherence usually leads to design errors that are not caught until well in to the implementation phase. Since the cost of redesign increases as the design moves through these three stages, redesign is the most expensive if not performed until the implementation phase, thus making the current incoherent methodology costly.Specification and Design Methodology for Real-Time Embedded Systems shows how designs targeting COTS MP technologies can be improved by providing a coherent coupling between these frameworks, a quality known as model continuity. This book presents a new specification and design methodology (SDM) which accomplishes the requirements specification, design exploration, and implementation of COTS MP-based signal processing systems by using powerful commercial frameworks that are intelligently integrated into a single domain-specific SDM. From the foreword: This book is remarkably practical. It provides an excellent snapshot of the state-of-the-art and gives the reader a good understanding of both the fundamental challenges of specification and design as well as a unified and quantified ability to assess a given methodology.

Real-time systems are defined as those for which correctness depends not only on the logical properties of the produced results, but also on the temporal properties of these results. In a database, real-time means that in addition to typical logical consistency constraints, such as a constraint on a data item's value, there are constraints on when transactions execute and on the `freshness' of the data transactions access. The challenges and tradeoffs faced by the designers of real-time database systems are quite different from those faced by the designers of general-purpose database systems. To achieve the fundamental requirements of timeliness and predictability, not only do conventional methods for scheduling and transaction management have to be redesigned, but also new concepts that have not been considered in conventional database systems or in real-time systems need to be added. Real-Time Database and Information Systems: Research Advances is devoted to new techniques for scheduling of transactions, concurrency management, transaction logging, database languages, and new distributed database architectures. Real-Time Database and Information Systems: Research Advances is primarily intended for practicing engineers and researchers working in the growing area of real-time database and information retrieval systems. For practitioners, the book will provide a much needed bridge for technology transfer and continued education. For researchers, the book will provide a comprehensive reference for well-established results. The book can also be used in a senior or graduate level course on real-time systems, real-time database systems, and database systems, or closely related courses.

Vorwort In der Natur entwickelten sich die Echtzeitsysteme seit einigen 100 Mil- Honen Jahren. Tierische Nervensysteme haben zur Aufgabe, auf die Nachrichten aus der Umwelt die Steuerungsbefehle an die aktiven Or- gane zu geben. Dabei spielen zum Beispiel bedingte Reflexe eine wichtige Rolle. Vielleicht kann man die Entstehung des Menschen etwa zu der Zeit ansetzen, als sein sich allmahlich entwickelndes Gehirn Gedanken entwickelte, deren Bedeutung in vorausplanender Weise iiber die gerade vorliegende Situation hinausging. Das fiihrte schliesslich unter anderem zum heutigen Wissenschaftler, der seine Theorien und Systeme aufgrund langwieriger Uberlegungen aufbaut. Die Entwicklung der Computer ging im wesentlichen den umgekehrten Weg. Zunachst diente sie nur der Durchfiihrung "starrer" Programme, wie z.B. das erste programmgesteuerte Rechengerat Z3, das der Unterzeichner im Jahre 1941 vorfiihren konnte. Es folgte unter an- derem ein Spezialgerat zur Fliigelvermessung, das man als den ersten Prozessrechner bezeichnen kann. Es wurden etwa vierzig als Analog- Digital-Wandler arbeitende Messuhren yom Rechnerautomaten abgele- sen und im Rahmen eines Programms als Variable verarbeitet. Abel' auch das erfolgte noch in starrer Reihenfolge. Die echte Prozesssteuerung - heute auch Echtzeitsysteme genannt - erfordert aber ein Reagieren auf bestandig wechselnde Situationen.

Despite the growing interest in Real-Time Database Systems, there is no single book that acts as a reference to academics, professionals, and practitioners who wish to understand the issues involved in the design and development of RTDBS. Real-Time Database Systems: Issues and Applications fulfills this need. This book presents the spectrum of issues that may arise in various real-time database applications, the available solutions and technologies that may be used to address these issues, and the open problems that need to be tackled in the future. With rapid advances in this area, several concepts have been proposed without a widely accepted consensus on their definitions and implications. To address this need, the first chapter is an introduction to the key RTDBS concepts and definitions, which is followed by a survey of the state of the art in RTDBS research and practice. The remainder of the book consists of four sections: models and paradigms, applications and benchmarks, scheduling and concurrency control, and experimental systems. The chapters in each section are contributed by experts in the respective areas. Real-Time Database Systems: Issues and Applications is primarily intended for practicing engineers and researchers working in the growing area of real-time database systems. For practitioners, the book will provide a much needed bridge for technology transfer and continued education. For researchers, this book will provide a comprehensive reference for well-established results. This book can also be used in a senior or graduate level course on real-time systems, real-time database systems, and database systems or closely related courses.

This book is a compilation of research accomplishments in the fields of modeling, simulation, and their applications, as presented at AsiaSim 2011 (Asia Simulation Conference 2011). The conference, held in Seoul, Korea, November 16-18, was organized by ASIASIM (Federation of Asian Simulation Societies), KSS (Korea Society for Simulation), CASS (Chinese Association for System Simulation), and JSST (Japan Society for Simulation Technology). AsiaSim 2011 provided a forum for scientists, academicians, and professionals from the Asia-Pacific region and other parts of the world to share their latest exciting research findings in modeling and simulation methodologies, techniques, and their tools and applications in military, communication network, industry, and general engineering problems.

Formal Techniques in Real-Time and Fault-Tolerant Systems focuses on the state of the art in formal specification, development and verification of fault-tolerant computing systems. The term `fault-tolerance' refers to a system having properties which enable it to deliver its specified function despite (certain) faults of its subsystem. Fault-tolerance is achieved by adding extra hardware and/or software which corrects the effects of faults. In this sense, a system can be called fault-tolerant if it can be proved that the resulting (extended) system under some model of reliability meets the reliability requirements. The main theme of Formal Techniques in Real-Time and Fault-Tolerant Systems can be formulated as follows: how do the specification, development and verification of conventional and fault-tolerant systems differ? How do the notations, methodology and tools used in design and development of fault-tolerant and conventional systems differ? Formal Techniques in Real-Time and Fault-Tolerant Systems is divided into two parts. The chapters in Part One set the stage for what follows by defining the basic notions and practices of the field of design and specification of fault-tolerant systems. The chapters in Part Two represent the `how-to' section, containing examples of the use of formal methods in specification and development of fault-tolerant systems. The book serves as an excellent reference for researchers in both academia and industry, and may be used as a text for advanced courses on the subject.

With the rapid growth of networking and high-computing power, the demand for large-scale and complex software systems has increased dramatically. Many of the software systems support or supplant human control of safety-critical systems such as flight control systems, space shuttle control systems, aircraft avionics control systems, robotics, patient monitoring systems, nuclear power plant control systems, and so on. Failure of safety-critical systems could result in great disasters and loss of human life. Therefore, software used for safety critical systems should preserve high assurance properties. In order to comply with high assurance properties, a safety-critical system often shares resources between multiple concurrently active computing agents and must meet rigid real-time constraints. However, concurrency and timing constraints make the development of a safety-critical system much more error prone and arduous. The correctness of software systems nowadays depends mainly on the work of testing and debugging. Testing and debugging involve the process of de tecting, locating, analyzing, isolating, and correcting suspected faults using the runtime information of a system. However, testing and debugging are not sufficient to prove the correctness of a safety-critical system. In contrast, static analysis is supported by formalisms to specify the system precisely. Formal verification methods are then applied to prove the logical correctness of the system with respect to the specification. Formal verifica tion gives us greater confidence that safety-critical systems meet the desired assurance properties in order to avoid disastrous consequences.

Sir Isaac Newton's philosophi Naturalis Principia Mathematica'(the Principia) contains a prose-style mixture of geometric and limit reasoning that has often been viewed as logically vague. In A Combination of Geometry Theorem Proving and Nonstandard Analysis, Jacques Fleuriot presents a formalization of Lemmas and Propositions from the Principia using a combination of methods from geometry and nonstandard analysis. The mechanization of the procedures, which respects much of Newton's original reasoning, is developed within the theorem prover Isabelle. The application of this framework to the mechanization of elementary real analysis using nonstandard techniques is also discussed.

The International Workshop on "The Internet Challenge: Technology and Applications" is the fifth in a successful series of workshops that were established by Shanghai Jiao Tong University and Technische Universitat Berlin. The goal of those workshops is to bring together researchers from both universities in order to exchange research results achieved in common projects of the two partner universities or to present interesting new work that might lead to new cooperation. The series of workshops started in 1990 with the "International Workshop on Artificial Intelligence" and was continued with the "International Workshop on Advanced Software Technology" in 1994. Both workshops have been hosted by Shanghai Jiao Tong University. In 1998 the third workshop took place in Berlin. This "International Workshop on Communication Based Systems" was essentially based on results from the Graduiertenkolleg on Communication Based systems that was funded by the German Research Society (DFG) from 1991 to 2000. The fourth "International Workshop on Robotics and its Applications" was held in Shanghai in 2000 supported by VDIIVDE-GMA and GI.

This volume contains a selection of papers that focus on the state-of the-art in formal specification and verification of real-time computing systems. Preliminary versions of these papers were presented at a workshop on the foundations of real-time computing sponsored by the Office of Naval Research in October, 1990 in Washington, D. C. A companion volume by the title Foundations of Real-Time Computing: Scheduling and Resource Management complements this hook by addressing many of the recently devised techniques and approaches for scheduling tasks and managing resources in real-time systems. Together, these two texts provide a comprehensive snapshot of current insights into the process of designing and building real time computing systems on a scientific basis. The notion of real-time system has alternative interpretations, not all of which are intended usages in this collection of papers. Different communities of researchers variously use the term real-time to refer to either very fast computing, or immediate on-line data acquisition, or deadline-driven computing. This text is concerned with the formal specification and verification of computer software and systems whose correct performance is dependent on carefully orchestrated interactions with time, e. g., meeting deadlines and synchronizing with clocks. Such systems have been enabled for a rapidly increasing set of diverse end-uses by the unremitting advances in computing power per constant-dollar cost and per constant-unit-volume of space. End use applications of real-time computers span a spectrum that includes transportation systems, robotics and manufacturing, aerospace and defense, industrial process control, and telecommunications."
