Grid Computing

www.ebooks.com/cj.asp?IID=1633320&cjsku=1633320...
Designed for senior undergraduate and first-year graduate students, Grid Computing : Techniques and Applications shows professors how to teach this subject in a practical way. Extensively classroom-tested, it covers job submission and scheduling, Grid security, Grid computing services and software tools, graphical user interfaces, workflow editors, and Grid-enabling applications. The book begins with an introduction that discusses the use of a Grid computing Web-based portal. It then examines the underlying action of job submission using a command-line interface and the use of a job scheduler. After describing both general Internet security techniques and specific security mechanisms developed for Grid computing, the author focuses on Web services technologies and how they are adopted for Grid computing. He also discusses the advantages of using a graphical user interface over a command-line interface and presents a graphical workflow editor that enables users to compose sequences of computational tasks visually using a simple drag-and-drop interface. The final chapter explains how to deploy applications on a Grid. The Grid computing platform offers much more than simply running an application at a remote site. It also enables multiple, geographically distributed computers to collectively obtain increased speed and fault tolerance. Illustrating this kind of resource discovery, this practical text encompasses the varied and interconnected aspects of Grid computing, including how to design a system infrastructure and Grid portal. Supplemental Web Resources The author's Web site offers various instructional resources, including slides and links to software for programming assignments. Many of these assignments do not require access to a Grid platform. Instead, the author provides step-by-step instructions for installing open-source software to deploy and test Web and Grid services, a Grid computing workflow editor to design and test workflows, and a Grid computing portal to deploy portlets.

Granular Computing

www.ebooks.com/cj.asp?IID=1255706&cjsku=1255706...
This book is about Granular Computing (GC) - an emerging conceptual and of information processing. As the name suggests, GC concerns computing paradigm processing of complex information entities - information granules. In essence, information granules arise in the process of abstraction of data and derivation of knowledge from information. Information granules are everywhere. We commonly use granules of time (seconds, months, years). We granulate images; millions of pixels manipulated individually by computers appear to us as granules representing physical objects. In natural language, we operate on the basis of word-granules that become crucial entities used to realize interaction and communication between humans. Intuitively, we sense that information granules are at the heart of all our perceptual activities. In the past, several formal frameworks and tools, geared for processing specific information granules, have been proposed. Interval analysis, rough sets, fuzzy sets have all played important role in knowledge representation and processing. Subsequently, information granulation and information granules arose in numerous application domains. Well-known ideas of rule-based systems dwell inherently on information granules. Qualitative modeling, being one of the leading threads of AI, operates on a level of information granules. Multi-tier architectures and hierarchical systems (such as those encountered in control engineering), planning and scheduling systems all exploit information granularity. We also utilize information granules when it comes to functionality granulation, reusability of information and efficient ways of developing underlying information infrastructures.

Business Computing

www.ebooks.com/cj.asp?IID=1256906&cjsku=1256906...
Betriebswirtschaftliche Probleme knnen oft nur mit Hilfe geeigneter Softwareprodukte gelst werden. Das vorliegende Buch fhrt den Leser umfassend in das Gebiet des Business Computing ein. Nach einer grundlegenden Darstellung der Funktionsweise von Computer und Betriebssystem werden u.a. die generischen Aspekte der Standardsoftware behandelt. Der Leser wird weitgehend unabhngig von proprietrer Software mit der Anwendung von Textverarbeitung (einschlielich einfacher Internetapplikationen), Tabellenkalkulation und Datenbank-Management-Systemen vertraut gemacht. Die notwendigen mathematischen Grundlagen und Programmierprinzipien werden knapp erlutert. Hinweise zur Erarbeitung von Prsentationen runden die Darstellung ab. Der Leser lernt, nicht nur unterschiedlichste betriebswirtschaftliche Probleme mit Hilfe von Standardsoftware zu lsen, sondern auch neue Softwareprodukte zu analysieren und die geeigneten fr sich auszuwhlen.

Trusted Computing

www.ebooks.com/cj.asp?IID=750728&cjsku=750728...
Trusted Computing markiert einen grundstzlichen Wandel der IT-Sicherheitsarchitekturen. Erstmals werden die Potenziale von sicherer integrierten Hard- und Software verfgbar. Seit 1999 sind die wesentlichen Konzepte, Standards, Baugruppen und Softwaremodule entwickelt und zur Anwendungsreife gebracht worden. Das Buch fasst die vorliegenden Grundlagen zusammen. Es behandelt erstmals wichtige Anwendungsszenarien mit signifikantem Sicherheitsgewinn fr IT-Systembetreiber und -anwender. Besonders bercksichtigt wird dabei Open Source Software als Beitrag zur Vertrauenswrdigkeit der Lsungen. Es wird gezeigt, dass Trusted Computing die traditionellen chipkartenbasierten Konzepte der IT-Sicherheit wirkungsvoll ergnzt und dass Datenschutz und andere rechtliche Vorgaben erfllt werden.

Ubiquitous Computing

www.ebooks.com/cj.asp?IID=750925&cjsku=750925...
Ubiquitous Computing has been the subject of discussion in various research areas for some time now. Over the past several years RFID and Near Field Communication (NFC) technologies have become the driving force behind the vision of Ubiquitous Computing. In particular, NFC could become a real Ubiquitous Computing technology in consumer hands if it succeeds in capturing distribution channels, for example due to integration into the mobile devices market. Even if that will be the case in the future, application developers and entrepreneurs interested in using RFID or NFC technologies will be faced with the challenges of negotiating the process of moving early prototypes into a final product. In particular, given the physical nature of the technology, it is imperative that the user be involved in the very early stages of development in order to bring successful, consumer-accepted applications to market. In 2009, NFC technology still finds itself in the starting blocksaccordingly, these research results come at the right time. Previous approaches to the challenge of developing NFC applications have neither applied research methods specific to Ubiquitous Computing, nor have they integrated the appropriate design guidelines. Florian Resatsch's work focuses specifically on these issues and makes use of a unified developmental and evaluation process model. The work draws on knowledge from a range of disciplines and combines these into a process for developing and evaluating Ubiquitous Computing applications using Near Field Communication (NFC) as an enabling technology.

Computing Networks

www.ebooks.com/cj.asp?IID=1124665&cjsku=1124665...
“Computing Networks” explores the core of the new distributed computing infrastructures we are using today:  the networking systems of clusters, grids and clouds. It helps network designers and distributed-application developers and users to better understand the technologies, specificities, constraints and benefits of these different infrastructures’ communication systems. Cloud Computing will give the possibility for millions of users to process data anytime, anywhere, while being eco-friendly. In order to deliver this emerging traffic in a timely, cost-efficient, energy-efficient, and reliable manner over long-distance networks, several issues such as quality of service, security, metrology, network-resource scheduling and virtualization are being investigated since 15 years. “Computing Networks” explores the core of clusters, grids and clouds networks, giving designers, application developers and users the keys to better construct and use these powerful infrastructures.
