This item is printed on demand - it takes 3-4 days longer - Neuware -The monograph is devoted to a systematic study of means of Hilbert space operators by a unified method based on the theory of double integral transformations and Peller's characterization of Schur multipliers. General properties on means of operators such as comparison results, norm estimates and convergence criteria are established. Aftersome general theory, special investigations are focused on three one-parameter families of A-L-G (arithmetic-logarithmic-geometric) interpolation means, Heinz-type means and binomial means. In particular, norm continuity in the parameter is examined for such means. Some necessary technical resultsare collected as appendices. 164 pp. Englisch.

D. thesis, Rudiger Wapler analyses the causes of the persistently high unemployment rates especially in continental Europe. Particular emphasis is placed on imperfect labour and product markets on the one hand, and on the numerous links between unemployment, innovations and growth on the other. Hence, Rudiger Wapler provides an important contribution towards a better understanding of both the development of labour markets as well as the dynamics of growth. To aid readers with only little prior knowledge of labour markets, the book presents the most common theories of unemployment: (1) trade-union models in which union bargaining power leads to wages above their market-clearing level, (2) efficiency-wage models in which employers voluntarily pay higher wages in order to motivate or discipline their workers or to reduce the job turnover rate, as well as (3) matching models in which unemployment is caused by the continuous turnover of jobs and workers. In addition, emphasis is placed on the fact that labour needs to be treated as heterogeneous, a fact often neg lected in the literature. Subsequently, these labour-market foundations are integrated with modern theories of innovations and growth, making the ap proach much more relevant and plausible. Without doubt, the generalisations of the models performed by Rudiger Wapler show that there are limits to such formal analysis. Due to the increasing number of interdependencies, it is doubtful whether even more complex models provide additional (usable) insights. 240 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -The increasing complexity of manufacturing systems as well as the overall demands for flexible and fault-tolerant control of production processes stimulates (among many others) two key emerging technologies that are already making an important breakthrough in the field of intelligent manufacturing, control, and diagnostics. These two paradigms are: - the holonic approach based on the event-driven control strategy, usually aimed at modular control systems that are directly physically linked with the manufacturing hardware equipment, and - the multi-agent approach developed in the area of distributed information processing. The research communities working in both these fields are approaching the problem of intelligent manufacturing from different viewpoints and, until recently, to a certain extent, in an independent way. We can however observe quite a clear convergence of these fields in the last few years: the communities have started to cooperate, joining efforts to solve the painful problems involved in achieving effective industrial practice. We can see convergence in the terminology, standards and methods being applied. 340 pp. Englisch.

They learn, predict, remember and adapt, protecting us from the maelstrom of pathogens that infect us daily. Computer Science frequently takes inspiration from the seemingly endless capabilities of natural systems. It should therefore be no s- prise that, like the eld of Arti cial Neural Networks inspired from brains, we now have a vigorous eld of research known as Arti cial Immune Systems (AIS), inspired by our own immune systems. Although still relatively new, the previous 10 years has seen the paradigm of AIS rapidly establish itself as an important biological metaphor. Researchers all over the world fruitfully exploit 'immunological ideas' in many di erent ways to provide mechanisms for tackling a wide variety of applications. In this volume we present the proceedings of ICARIS 2003, the 2nd Int- national Conference on Arti cial Immune Systems. This was the second int- national conference entirely dedicated to the eld, and followed the extremely successful rst conference held in Canterbury, UK in 2002. The number and - versityofpapersinthisyear'sconferenceisatributetotheever-growingnumber ofresearchersinthearea,andrepresentativeofthesolidfoundationofworkthat now exists in this area. The range of topics considered is wide. For example, at one end of the spectrum we see a selection of papers providing a necessary t- oretical grounding for the eld. At the other end, we have an exciting range of applications to real-world problems, covering, for example, job-shop scheduling and fault detection in refrigeration systems. 316 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -This volume contains the proceedings of the 14th International Conference on ConcurrencyTheory(CONCUR2003)heldinMarseille,France,September3 5, 2003. The conference was hosted by the Universit edeProvenceandtheLa- ratoire d Informatique Fondamentale de Marseille (LIF). The purpose of the CONCUR conferences is to bring together researchers, developers, and students in order to advance the theory of concurrency, and promote its applications. Interest in this topic is continuously growing, as a consequence of the importance and ubiquity of concurrent systems and their applications, and of the scienti c relevance of their fundations. The scope of the conference covers all areas of semantics, logics, and veri cation techniques for concurrent systems. Topics include concurrency-related aspects of: models of computation and semantic domains, process algebras, Petri nets, event struc- res, real-time systems, hybrid systems, decidability, model-checking, veri cation and re nement techniques, term and graph rewriting, distributed programming, logic constraint programming, object-oriented programming, types systems and algorithms, case studies, and tools and environments for programming and - ri cation. Of the 107 papers submitted this year, 29 were accepted for presentation. Four invited talks were given at the conference: on Distributed Monitoring of Concurrent and Asynchronous Systems by Albert Beneveniste, on Quantitative Veri cation via the MU-Calculus by Luca De Alfaro, on Input-Output Au- mata: Basic, Timed, Hybrid, Probabilistic, Dynamic, . . by Nancy Lynch, and on Composition of Cryptographic Protocols in a Probabilistic Polynomial-Time Process Calculus by Andre Scedrov. 544 pp. Englisch.

Over the past few years, agent technologyhas emerged as a powerful force in computing. Agent technology may well form the foundation for the next gen- ation of computing systems. New and innovative agent concepts and techniques may bring further developments to this exploding area of research. Such work is often strongly inspired by theoretical or empirical studies of human behavior, social intelligence, psychology, arts, biology, computer science and philosophy. Thisworkshopaimedatbringingtogether,inaninterdisciplinaryeve nt,or- inal thinkers, practitioners and academics with an interest in radical (very - novative) concepts for agent-based systems. The workshop provided a forum to present the latest research ndings in many aspects of agent technology. The - ganizers welcomed participation by those working in agent architectures, agent communities, agent communications, agent modeling, agent applications and other agent-related areas. We were particularly seeking papers on novel and - novative ideas, pushing the envelope of current agent technology. Contributions without a prototype or working system, i.e., purely conceptual contributions, were welcomed, and 'out-of-the-box' thinkers were especially encouraged to participate. The workshop was structured so as to allow the participants adequate time for discussion and interaction, to exchange ideas and re ect on the motivations, scienti c grounds and practical consequences of the concepts presented. 492 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Nowadays, societies crucially depend on high-quality software for a large part of their functionalities and activities. Therefore, software professionals, researchers, managers, and practitioners alikehave to competently decide what software technologies and products to choose for which purpose.For various reasons, systematic empirical studies employing strictly scientific methods are hardly practiced in software engineering. Thus there is an unquestioned need for developing improved and better-qualified empirical methods, for their application in practice and for dissemination of the results.This book describes different kinds of empirical studies and methods for performing such studies, e.g., for planning, performing, analyzing, and reporting such studies. Actual studies are presented in detail in various chapters dealing with inspections, testing, object-oriented techniques, and component-based software engineering. 292 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Thisvolumecontainsaselectionofpapersfromthe4thInternationalConference on the Practice and Theory of Automated Timetabling (PATAT 2002) held in Gent, August 21-23, 2002. Since the rst conference in Edinburgh in 1995, the range of timetabling applications at the conferences has become broader and more diverse. In the s- ected papers volume from the 1995 conference, there were just two contributions (out of 22) which did not speci cally address school and university timetabling. In the selected papers volume from the 1997 conference in Toronto, the number of papers which tackled non-educational problems increased. Two of the papers addressed more than one timetabling application. In both of these papers, educational applications were considered in addition to other applications. A further three papers were concerned with non-educational applications. The conference steering and programme committees have worked hard to attract a wide range of timetabling applications. In the conference held in Konstanz in 2000, the diversi cation of timetabling problems increased signi cantly. Of the 21 selected papers in the postconference volume, just 13 were speci cally concerned with educational timetabling. In the previous volumes, the papers had been sectioned according to solution technique. In the Konstanz volume the papers were classi ed according to application domains. One section of the volume was entitled 'Employee Timetabling,' while sports timetabling, air eet scheduling, and general software architectures for timetabling were also represented. In the present volume, more than one-third of the 21 papers discuss problems in application areas other than academic and educational ones. Sports timetabling and hospital timetabling are particularly well represented. 380 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -These are the proceedings of the 7th International Workshop on Cooperative Information Agents (CIA 2003), held at the Sonera Conference Center in H- sinki, Finland, August 27-29, 2003. It was co-located with the 4th Agentcities Information Days. One key challenge of developing advanced agent-based information systems is to balance the autonomy of networked data and knowledge sources with the pot- tial payo of leveraging them by the appropriate use of intelligent information agents on the Internet. An information agent is a computational software entity thathasaccesstooneormultiple,heterogeneous,anddistributeddataandinf- mation sources; proactively searches for and maintains relevant information on behalfofitshumanusersorotheragents,preferablyjust-in-time. Inotherwords, it is managing and overcoming the di culties associated with information ov- load in the open and exponentially growing Internet and Web. Depending on the application and tasks at hand information agents may collaborate in open, n- worked data and information environments to provide added value to a variety of applications in di erent domains. Thus, research and development of inf- mation agents is inherently interdisciplinary: It requires expertise in information retrieval, arti cial intelligence, database systems, human-computer interaction, and Internet and Web technology.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is concerned with the rich and fruitful interplay between the fields of computational logic and machine learning. The intended audience is senior undergraduates, graduate students, and researchers in either of those fields. For those in computational logic, no previous knowledge of machine learning is assumed, and for those in machine learning no previous knowledge of computational logic is assumed.The logic used throughout the book is a higher-order one, since higher-order functions can have other functions as arguments and this capability can be exploited to provide abstractions for knowledge representation, methods for constructing predicates, and a foundation for logic-based computation.The book should be of interest to researchers in machine learning, especially those who study learning methods for structured data. Throughout, great emphasis is placed on learning comprehensible theories. The book serves as an introduction for computational logicians to machine learning, a particularly interesting and important application area of logic, and also provides a foundation for functional logic programming languages. 272 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -Human performance in visual perception by far exceeds the performance of contemporary computer vision systems. While humans are able to perceive their environment almost instantly and reliably under a wide range of conditions, computer vision systems work well only under controlled conditions in limited domains.This booksets out to reproduce the robustness and speed of human perception by proposing a hierarchical neural network architecture for iterative image interpretation. The proposed architecture can be trained using unsupervised and supervised learning techniques. Applications of the proposed architecture are illustrated using small networks. Furthermore, several larger networks were trained to perform various nontrivial computer vision tasks. 240 pp. Englisch.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For quite some time, in systems and software design, security only came as a second thought or even as a nice-to-have add-on. However, since the breakthrough of the Internet as a virtual backbone for electronic commerce and similar applications, security is now recognized as a fundamental requirement. This book presents a systematic security improvement approach based on the pattern paradigm. The author first clarifies the key concepts of security patterns, defines their semantics and syntax, demonstrates how they can be used, and then compares his model with other security approaches. Based on the author's model and best practice in security patterns, security novices are now in a position to understand how security experts solve problems and can basically act like them by using the patterns available as building blocks for their designs. 224 pp. Englisch.

Buch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The simulation of technological and environmental flows is very important for many industrial developments. A major challenge related to their modeling is to involve the characteristic turbulence that appears in most of these flows. The traditional way to tackle this question is to use deterministic equations where the effects of turbulence are directly parametrized, i. e. , assumed as functions of the variables considered. However, this approach often becomes problematic, in particular if reacting flows have to be simulated. In many cases, it turns out that appropriate approximations for the closure of deterministic equations are simply unavailable. The alternative to the traditional way of modeling turbulence is to construct stochastic models which explain the random nature of turbulence. The application of such models is very attractive: one can overcome the closure problems that are inherent to deterministic methods on the basis of relatively simple and physically consistent models. Thus, from a general point of view, the use of stochastic methods for turbulence simulations seems to be the optimal way to solve most of the problems related to industrial flow simulations. However, it turns out that this is not as simple as it looks at first glance. The first question concerns the numerical solution of stochastic equations for flows of environmental and technological interest. To calculate industrial flows, 3 one often has to consider a number of grid cells that is of the order of 100 . 240 pp. Englisch.
