One of the most challenging issues for the intelligent decision systems is to effectively manage the large-scale complex distributed environments such as computational clouds, grids, ad hoc and P2P networks, under the different types of users, their relations, and real-world uncertainties. In this context the IT resources and services usually belong to different owners (institutions, enterprises, or individuals) and are managed by different administrators. These administrators conform to different sets of rules and configuration directives, and can impose different usage policies on the system users. Additionally, uncertainties are presented in various types of information that are incomplete, imprecise, fragmentary or overloading, which hinders the full and precise determination of the evaluation criteria, their subsequent and selection, the assignment scores, and eventually the final integrated decision result.

This book presents new ideas, analysis, implementations and evaluation of the next generation intelligent techniques for solving complex decision problems in large-scale distributed systems. In 15 chapters several important formulations of the decision problems in heterogeneous environments are identified and a review of the recent approaches, from game theoretical models and computational intelligent techniques, such as genetic, memetic and evolutionary algorithms, to intelligent multi-agent systems and networking are presented. We believe that this volume will serve as a reference for the students, researchers and industry practitioners working in or are interested in joining interdisciplinary works in the areas of intelligent decision systems using emergent distributed computing paradigms. It will also allow newcomers to grasp key concerns and potential solutions on the selected topics."

What is exactly "Safety"? A safety system should be defined as a system that will not endanger human life or the environment. A safety-critical system requires utmost care in their specification and design in order to avoid possible errors in their implementation that should result in unexpected system's behavior during his operating "life." An inappropriate method could lead to loss of life, and will almost certainly result in financial penalties in the long run, whether because of loss of business or because the imposition of fines. Risks of this kind are usually managed with the methods and tools of the "safety engineering." A life-critical system is designed to 9 lose less than one life per billion (10 ). Nowadays, computers are used at least an order of magnitude more in safety-critical applications compared to two decades ago. Increasingly electronic devices are being used in applications where their correct operation is vital to ensure the safety of the human life and the environment. These application ranging from the anti-lock braking systems (ABS) in automobiles, to the fly-by-wire aircrafts, to biomedical supports to the human care. Therefore, it is vital that electronic designers be aware of the safety implications of the systems they develop. State of the art electronic systems are increasingly adopting progr- mable devices for electronic applications on earthling system. In particular, the Field Programmable Gate Array (FPGA) devices are becoming very interesting due to their characteristics in terms of performance, dimensions and cost.

DAPSY (Austrian-Hungarian Workshop on Distributed and Parallel Systems) is an international conference series with biannual events dedicated to all aspects of distributed and parallel computing. DAPSY started under a different name in 1992 (Sopron, Hungary) as regional meeting of Austrian and Hungarian researchers focusing on transputer-related parallel computing; a hot research topic of that time. A second workshop followed in 1994 (Budapest, Hungary). As transputers became history, the scope of the workshop widened to include parallel and distributed systems in general and the 1st DAPSYS in 1996 (Miskolc, Hungary) reflected the results of these changes.

Distributed and Parallel Systems: Cluster and Grid Computing is an edited volume based on DAPSYS, 2004, the 5th Austrian-Hungarian Workshop on Distributed and Parallel Systems. The workshop was held in conjunction with EuroPVM/MPI-2004, Budapest, Hungary September 19-22, 2004.

Military and intelligence leaders agree that the next major war is not likely to be fought on the battleground but in cyber space. Richard Stiennon argues the era of cyber warfare has already begun. Recent cyber attacks on United States government departments and the Pentagon corroborate this claim. China has compromised email servers at the German Chancellery, Whitehall, and the Pentagon. In August 2008, Russia launched a cyber attack against Georgia that was commensurate with their invasion of South Ossetia. This was the first time that modern cyber attacks were used in conjunction with a physical attack. Every day, thousands of attempts are made to hack into America's critical infrastructure. These attacks, if successful, could have devastating consequences. In Surviving Cyberwar, Stiennon introduces cyberwar, outlines an effective defense against cyber threats, and explains how to prepare for future attacks. The book: *begins with Shawn Carpenter and his discovery that China had hacked into his work place, Sandia Labs; *follows the rise of cyber espionage on the part of the Chinese People's Liberation Army (PLA) as increasingly sophisticated and overt attacks are carried out against government and military networks around the world; *moves from cyber espionage to cyberwar itself, revealing the rise of distributed denial of service (DDoS) as a means of attacking servers, websites, and countries; *provides a historical perspective on technology and warfare is provided, drawing on lessons learned from Sun Tsu to Lawrence of Arabia to Winston Churchill; and *finishes by considering how major democracies are preparing for cyberwar and predicts ways that a new era of cyber conflict is going to impact the Internet, privacy, and the way the world works. This text is a stimulating and informative look at one of the gravest threats to Homeland Security today, offering new insights to technologists on the front lines, helping policy makers understand the challenges they face, and providing guidance for every organization to help reduce exposure to cyber threats. It is essential reading for anyone concerned with the current geopolitical state of affairs.

In our modern information societies, we not only use and welcome computers; we are highly dependent upon them. There is a downside of this kind of progress, however. Computers are not 100% reliable. They are insecure. They are vulnerable to attackers. They can either be attacked directly, to disrupt their services, or they can be abused in clever ways to do the bidding of an attacker as a dysfunctional user. Decision-makers and experts alike always struggle with the amount of interdisciplinary knowledge needed to understand the nuts and bolts of modern information societies and their relation to security, the implications of technological or political progress or the lack thereof. This holds in particular for new challenges to come. These are harder to understand and to categorize; their development is difficult to predict. To mitigate this problem and to enable more foresight, The Secure Information Society provides an interdisciplinary spotlight onto some new and unfolding aspects of the uneasy relationship between information technology and information society, to aid the dialogue not only in its current and ongoing struggle, but to anticipate the future in time and prepare perspectives for the challenges ahead.

Networks have become nearly ubiquitous and increasingly complex, and their support of modern enterprise environments has become fundamental. Accordingly, robust network management techniques are essential to ensure optimal performance of these networks. This monograph treats the application of numerous graph-theoretic algorithms to a comprehensive analysis of dynamic enterprise networks. Network dynamics analysis yields valuable information about network performance, efficiency, fault prediction, cost optimization, indicators and warnings. Based on many years of applied research of generic network dynamics, this work covers a number of elegant applications (including many new and experimental results) of traditional graph theory algorithms and techniques to computationally tractable network dynamics analysis to motivate network analysts, practitioners and researchers alike. The material is also suitable for graduate courses addressing state-of-the-art applications of graph theory in analysis of dynamic communication networks, dynamic databasing, and knowledge management.

The purpose of this volume is to shape conceptual tools to understand the impact of new information and communication technologies (ICTs) on the organization of universities. Traditional research-based universities, the most typical representatives of the higher education system, find themselves challenged by the speed and the wide range of technical innovations, but also by a vast array of implicit assumptions and explicit promises associated with the distribution of digital media.

The author observes that as universities increasingly use digital media (computers and the Internet) to accomplish their tasks, a transformation takes place in an "evolutionary" rather than in a revolutionary way.Using the University of Klagenfurt as an in-depth case study, he explores such dynamic issues as how digital media affect the practice of research, the preservation and dissemination of knowledge (for example, through publishing and archiving), and delivery of education at universities.More broadly, he considers issues of organizational culture and design, administration, and leadership as universities integrate digital technologies into all aspects of their operations."

In the last few years, a stimulating idea is fast emergingin the wireless scenario: the pervasive presence around us of a variety of "things" or "objects," such as RFID, sensors, actuators, mobile phones, which, through unique addressing schemes, are able to interact with each other and cooperate with their neighboring "smart" c- ponents to reach common goals. This novel paradigm, named "The Internet of Things" (IoT) continues on the path set by the concept of smart environments and paves the way to the depl- ment of numerous applications with a signi cant impact on many elds of future every-day life. In this context, logistics, Intelligent Transportation Systems (ITS), business/process management, assisted living, and e-health are only a few examples of possible application elds in which this novel paradigm will play a leading role in the next future. Actually, manychallengingissues still needto be addressedand both technolo- calandsocialnodesuntiedbeforethe IoTideabeingwidelyaccepted.Centralissues are making a full interoperabilityof such devices possible, enablingtheir adaptation and autonomousbehavior, as well as guaranteeingtrust, privacy, and security. Also, the IoT idea poses several new problemsconcerningthe networkingaspects. In fact, the "things" composing the IoT will be characterized by low resources in terms of both computation and energy capacity. Accordingly, the proposed solutions need to payspecial attentionto resourceef ciencybesides the obviousscalability problems. The papers included in this volume present a picture of the current state of the art on the above issues; more speci cally, concepts and ideas are discussed on n- working, middleware, security and privacy, RFID and sensor networks, as well as electromagnetic aspects.
