Taschenbuch. Condición: Neu. Neuware -As models and paradigms, patterns have been helping to orient architects since the Middle Ages. But patterns are also the basis of the history of ornament, an aesthetic phenomenon that links all times and cultures at a fundamental level. Ornament ¿ and hence pattern as well ¿ was abolished by the avant-garde in the first half of the twentieth century, but the notion of pattern has taken on new meaning and importance since the 1960s.Complexity research has ultimately shown that even highly complex, dynamic patterns may be based on simple behavioral rules, and that has allowed the notions of pattern and pattern formation to take on new meanings, that are also central for architecture.Today the use of generative computerized methods is opening up new ways of talking about an idea that is becoming increasingly abstract and dynamic. Pattern explores the question: what are the notions of pattern that must be discussed in the context of contemporary architecture Birkhäuser Verlag GmbH, Im Westfeld 8, 4055 Basel 108 pp. Englisch.

Buch. Condición: Neu. Neuware - It's been thirty-five years since people last trod the dusty plains of the Moon. Over the course of six landings from 1969 to 1972, twelve men explored, four-wheeled, dug and hiked across the lunar surface. Now, NASA has plans for a seventh landing on the Moon. This time, they want to stay. NASA's plans, dubbed the Constellation architecture, involve the largest launch vehicle ever built, new types of propulsion, and a six-person vehicle to ferry crews from Earth to the Moon. But NASA's plans go far beyond Luna. Eventually, the lessons learned on the Moon's outpost at Shackleton Crater will teach us how to live-permanently-on the most Earthlike world in our solar system, Mars. NASA will have company: plans for future lunar exploration are being drawn by Europe, Japan, China and India.While specific hardware and mission details will be in flux for some time, the overarching goals, strategies and inspiration for the seventh landing will not change. This book will choose a typical scenario for getting to the Moon that embraces the spirit of exploration embodied by NASA's Constellation architecture. Each chapter moves from a general description to the specific nuts-and-bolts of engineering and science. The Seventh Landing reveals the very latest strategies for how we'll get to the Moon, what we know today, what we want to find out, and what life will be like at the first true outposts on the Moon and Mars.

Taschenbuch. Condición: Neu. Neuware -Data management, knowledge discovery, and knowledge processing are core and hot topics in computer science. They are widely accepted as enabling technologies for modern enterprises, enhancing their performance and their decision making processes. Since the 1990s the Internet has been the outstanding driving force for application development in all domains. An increase in the demand for resource sharing (e. g. , computing resources, s- vices, metadata, data sources) across different sites connected through networks has led to an evolvement of data- and knowledge-management systems from centralized systems to decentralized systems enabling large-scale distributed applications prov- ing high scalability. Current decentralized systems still focus on data and knowledge as their main resource characterized by: heterogeneity of nodes, data, and knowledge autonomy of data and knowledge sources and services large-scale data volumes, high numbers of data sources, users, computing resources dynamicity of nodes These characteristics recognize: (i) limitations of methods and techniques developed for centralized systems (ii) requirements to extend or design new approaches and methods enhancing efficiency, dynamicity, and scalability (iii) development of large scale, experimental platforms and relevant benchmarks to evaluate and validate scaling Feasibility of these systems relies basically on P2P (peer-to-peer) techniques and agent systems supporting with scaling and decentralized control. Synergy between Grids, P2P systems and agent technologies is the key to data- and knowledge-centered systems in large-scale environments. 371 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -The vast majority of computers in use today are encapsulated within other systems. In contrast to general-purpose computers that run an endless selection of software, these embedded computers are often programmed for a very specific, low-level and often mundane purpose. Low-end microcontrollers, costing as little as one dollar, are often employed by engineers in designs that utilize only a small fraction of the processing capability of the device because it is either more cost-effective than selecting an application-specific part or because programmability offers custom functionality not otherwise available.Embedded Systems Interfacing for Engineers using the Freescale HCS08 Microcontroller is a two-part book intended to provide an introduction to hardware and software interfacing for engineers. Building from a comprehensive introduction of fundamental computing concepts, the book suitable for a first course in computer organization for electrical or computer engineering students with a minimal background in digital logic and programming. In addition, this book can be valuable as a reference for engineers new to the Freescale HCS08 family of microcontrollers. The HCS08 processor architecture used in the book is relatively simple to learn, powerful enough to apply towards a wide-range of interfacing tasks, and accommodates breadboard prototyping in a laboratory using freely available and low-cost tools.In Part II: Digital and Analog Hardware Interfacing, hardware and software interfacing concepts are introduced. The emphasis of this work is on good hardware and software engineering design principles. Device drivers are developed illustrating the use of general-purpose and special-purpose digital I/O interfaces, analog interfaces, serial interfaces and real-time I/O processing. The hardware side of each interface is described and electrical specifications and related issues are considered. The first part of the book provides the programming skills necessary to implement the software in this part.Table of Contents: Introduction to the MC9S08QG4/8 Hardware / Analog Input / Serial Communication / Real-Time I/O ProcessingSpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 140 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Jordan Canonical Form (JCF) is one of the most important, and useful, concepts in linear algebra. The JCF of a linear transformation, or of a matrix, encodes all of the structural information about that linear transformation, or matrix. This book is a careful development of JCF. After beginning with background material, we introduce Jordan Canonical Form and related notions: eigenvalues, (generalized) eigenvectors, and the characteristic and minimum polynomials. We decide the question of diagonalizability, and prove the Cayley-Hamilton theorem. Then we present a careful and complete proof of the fundamental theorem: Let V be a finite-dimensional vector space over the field of complex numbers C, and let T : V ¿ V be a linear transformation. Then T has a Jordan Canonical Form. This theorem has an equivalent statement in terms of matrices: Let A be a square matrix with complex entries. Then A is similar to a matrix J in Jordan Canonical Form, i.e., there is an invertible matrix P and a matrix J in Jordan Canonical Form with A = PJP-1. We further present an algorithm to find P and J, assuming that one can factor the characteristic polynomial of A. In developing this algorithm we introduce the eigenstructure picture (ESP) of a matrix, a pictorial representation that makes JCF clear. The ESP of A determines J, and a refinement, the labeled eigenstructure picture (¿ESP) of A, determines P as well. We illustrate this algorithm with copious examples, and provide numerous exercises for the reader.

Buch. Condición: Neu. Neuware - Wilfried Martens is one of the most distinguished politicians to come from Belgium in the last ffty years. In his long poli- cal career, he has always fought for the implementation of his goals with passion and deep conviction. What has to be mentioned frst in this context is his s- cessful advocacy of federalism in his home country, Belgium. Already in his time as chair of the CVP youth league from 1967 to 1972, groundbreaking manifestos on Belgium¿s federali- tion were written under his auspices. Later on, as President of the CVP, he succeeded in negotiating the Egmont Pact, whose essential elements form part of today¿s federal Belgian C- stitution. He served as Prime Minister for more than a decade, and in this role he convinced the regions and linguistic groups of his country, which were often at odds with each other, of the necessity for cooperation and solidarity.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 296 pp. Englisch.

Buch. Condición: Neu. Prusinkiewicz, Przemyslaw; Fowler, Deborah R. Ilustrador. Neuware -The pigment patterns on tropical shells are of great beauty and diversity. Their mixture of regularity and irregularity is fascinating. A particular pattern seems to follow particular rules but these rules allow variations. No two shells are identical. The motionless patterns appear to be static, and, indeed, they consist of calci ed material. However, as will be shown in this book, the underlying mechanism that generates this beauty is eminently dynamic. It has much in common with other dynamic systems that generate patterns, such as a wind-sand system that forms large dunes, or rain and erosion that form complex rami ed river systems. On other shells the underlying mechanism has much in common with waves such as those commonly observed in the spread of an epidemic. A mollusk can only enlarge its shell at the shell margin. In most cases, only at this margin are new elements of the pigmentation pattern added. Therefore, the shell pattern preserves the record of a process that took place over time in a narrow zone at the growing edge. A certain point on the shell represents a certain moment in its history. Like a time machine one can go into the past or the future just by turning the shell back and forth. Having this complete historical record opens the possibility of decoding the generic principles behind this beauty. 269 pp. Englisch.

Buch. Condición: Neu. Prusinkiewicz, Przemyslaw; Fowler, Deborah R. Ilustrador. Neuware -The patterns on the shells of tropical sea snails are not only compellingly beautiful but also tell a tale of biological development. The decorative patterns are records of their own genesis, which follows laws like those of dune formation or the spread of a flu epidemic. Hans Meinhardt has analyzed the dynamical processes that form these patterns and retraced them faithfully in computer simulations. His book is exciting not only for the astonishing scientific knowledge it reveals but also for its fascinating pictures.

Taschenbuch. Condición: Neu. Neuware -Engineers work in an increasingly complex entanglement of ideas, people, cultures, technology, systems and environments. Today, decisions made by engineers often have serious implications for not only their clients but for society as a whole and the natural world. Such decisions may potentially influence cultures, ways of living, as well as alter ecosystems which are in delicate balance. In order to make appropriate decisions and to co-create ideas and innovations within and among the complex networks of communities which currently exist and are shaped by our decisions, we need to regain our place as professionals, to realise the significance of our work and to take responsibility in a much deeper sense. Engineers must develop the 'ability to respond' to emerging needs of all people, across all cultures. To do this requires insights and knowledge which are at present largely within the domain of the social and political sciences but which need to be shared with our students in ways which are meaningful and relevant to engineering. This book attempts to do just that. In Part 1 Baillie introduces ideas associated with the ways in which engineers relate to the communities in which they work. Drawing on scholarship from science and technology studies, globalisation and development studies, as well as work in science communication and dialogue, this introductory text sets the scene for an engineering community which engages with the public. In Part 2 Catalano frames the thinking processes necessary to create ethical and just decisions in engineering, to understand the implications of our current decision making processes and think about ways in which we might adapt these to become more socially just in the future. In Part 3 Baillie and Catalano have provided case studies of everyday issues such as water, garbage and alarm clocks, to help us consider how we might see through the lenses of our new knowledge from Parts 1 and 2 and apply this to our every day existence as engineers.Table of Contents: Introduction / Engineering and Society / Engineering and the Public / Globalisation, Development, and TechnologySpringer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 116 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -GECON - Grid Economics and Business Models Cloud computing is seen by many people as the natural evolution of Grid computing concepts. Both, for instance, rely on the use of service-based approaches for pro- sioning compute and data resources. The importance of understanding business m- els and the economics of distributed computing systems and services has generally remained unchanged in the move to Cloud computing. This understanding is nec- sary in order to build sustainable e-infrastructure and businesses around this paradigm of sharing Cloud services. Currently, only a handful of companies have created s- cessful businesses around Cloud services. Among these, Amazon and Salesforce (with their offerings of Elastic Compute Cloud and force. com among other offerings) are the most prominent. Both companies understand how to charge for their services and how to enable commercial transactions on them. However, whether a wide-spread adoption of Cloud services will occur has to seen. One key enabler remains the ability to support suitable business models and charging schemes that appeal to users o- sourcing (part of) their internal business functions. The topics that have been addressed by the authors of accepted papers reflect the above-described situation and the need for a better understanding of Grid economics. The topics range from market mechanisms for trading computing resources, capacity planning, tools for modeling economic aspects of service-oriented systems, archit- tures for handling service level agreements, to models for economically efficient resource allocation.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 196 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Data warehousing and knowledge discovery are increasingly becoming mission-critical technologies for most organizations, both commercial and public, as it becomes incre- ingly important to derive important knowledge from both internal and external data sources. With the ever growing amount and complexity of the data and information available for decision making, the process of data integration, analysis, and knowledge discovery continues to meet new challenges, leading to a wealth of new and exciting research challenges within the area. Over the last decade, the International Conference on Data Warehousing and Knowledge Discovery (DaWaK) has established itself as one of the most important international scientific events within data warehousing and knowledge discovery. DaWaK brings together a wide range of researchers and practitioners working on these topics. The DaWaK conference series thus serves as a leading forum for discu- ing novel research results and experiences within data warehousing and knowledge th discovery. This year¿s conference, the 11 International Conference on Data Wa- housing and Knowledge Discovery (DaWaK 2009), continued the tradition by d- seminating and discussing innovative models, methods, algorithms, and solutions to the challenges faced by data warehousing and knowledge discovery technologies.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 496 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -Basic research discusses the implication of pancreatic stress protein in acute pancreatitis and pancreatic cancer and their possible role as therapeutic targets. Also, very original results show the unexpected role of lipids as mediators during acute pancreatitis. Gene screening strategies allow the detection of the genes responsbile for gemcitabine resistance of pancreatic cancer cells. They lead to the selection of several target genes, in order to suppress the resistance of cells to gemcitabine treatment. The mechanism by which tetrahydrocannabinol is anti-tumoral in pancreatic cancer cells is presented and the use of THC as a promising new therapeutic agent is discussed.Genetic data are shown concerning hundreds of families with hereditary chronic pancreatitis and their possible role in the pathogenesis of the disease. Another very original study addresses the prevention and treatment of pancreatic diseases with diat.In clinical research, convincing data about the use of endoscopic sphicterotomy in the management of acute bilary pancreatitis is presented, based on the experience of a Center highly specialized in pancreatic diseases.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 104 pp. Englisch.

Taschenbuch. Condición: Neu. Neuware -After the initial enthusiastic initiatives and investments and the eventual bubble, el- tronic commerce (EC) has changed and evolved into a well-established and founded reality both from a technological point of view and from a scientific one. Nevert- less, together with its evolution, new challenges and topics have emerged as well as new questions have been raised related to many aspects of EC. Keeping in mind the experience and the tradition of the past editions of EC-Web, we tried, for its 10th edition, to introduce some meaningful innovations about the structure and the sci- tific organization of the conference. Our main target was to highlight the autonomous role of the different (sometimes heterogeneous) aspects of EC, without missing their interdisciplinary scope. This required the conference to be organized into four ¿mi- conferences,' each for a relevant area of EC and equipped with a corresponding Area Chair. Both the submission and the review process took into account the organization into four tracks, namely: ¿Service-Oriented E-Commerce and Business Processes,¿ ¿Recommender Systems,¿ ¿E-Payment, Security and Trust¿ and ¿Electronic C- merce and Web 3. 0. ¿ Therefore, the focus of the conference was to cover aspects related to the theoretical foundation of EC, business processes as well as new - proaches exploiting recently emerged technologies and scenarios such as the Semantic Web, Web services, SOA architectures, mobile and ubiquitous computing, just to cite a few. 392 pp. Englisch.

Neuware -In todayís competitive and highly dynamic environment, analyzing data to understand how the business is performing, to predict outcomes and trends, and to improve the effectiveness of business processes underlying business operations has become cri- cal. The traditional approach to reporting is no longer adequate, users now demand easy-to-use intelligent platforms and applications capable of analyzing real-time bu- ness data to provide insight and actionable information at the right time. The end goal is to improve the enterprise performance by better and timelier decision making, - abled by the availability of up-to-date, high-quality information. As a response, the notion of 'real-time enterprise' has emerged and is beginning to be recognized in the industry. Gartner defines it as ¿using up-to-date information, getting rid of delays, and using speed for competitive advantage is what the real-time enterprise is all about. . . Indeed, the goal of the real-time enterprise is to act on events as they happen. ¿ Although there has been progress in this direction and many com- nies are introducing products toward making this vision a reality, there is still a long way to go. In particular, the whole lifecycle of business intelligence requires new techniques and methodologies capable of dealing with the new requirements imposed by the real-time enterprise.Springer Verlag GmbH, Tiergartenstr. 17, 69121 Heidelberg 136 pp. Englisch.
