Communication networks and computer systems research is entering a new phase in which many of the established models and techniques of the last twenty years are being challenged. The research community is continuing to free itself from past intellectual constraints so that it may fully exploit the convergence of computing and communications. Evaluating the performance of emerging communications and computer systems constitutes a huge challenge. Thus, current research provides a set of heterogeneous tools and techniques embracing the uncertainties of time and space varying environments when the requests for diverse services are made in real time, and with very different quality of service expectations.These novel techniques will lead to fast and economic service deployment and effective dynamic resource management, and hence to new business strategies and infrastructures that will facilitate the emergence of future services and applications.This volume contains contributions and presentations made by leading international researchers at a workshop which was held in April 2004 to honour Professor Erol Gelenbe on the occasion of his inaugural lecture as the Dennis Gabor Chair at Imperial College London.
From buying and selling PC hardware to product development and selling services, "Start Your Own Computer Business: The Unembellished Guide" offers a realistic picture of making it on your own. Bestselling author, Morris Rosenthal, has 15 years of experience in the computer business, building and repairing thousands of PCs and helping hundreds of customers. The book mixes practical advice and cautions with real-world anecdotes of successes and failures. Dollars and cents play a prominent role in the book, as Rosenthal stresses that the real challenge of succeeding in the computer business is the business part of the equation. Managing employees, inventory and scarce financial resources are covered, along with how to remain sane and when to quit. The book is illustrated with a series of original cartoons on the computer business subject.
E-based systems are ubiquitous in the modern world with applications spanning e-commerce, WLANs, health care and government organisations. The secure transfer of information has therefore become a critical area of research, development, and investment. This book presents the fundamental concepts and tools of e-based security and its range of applications. The core areas of e-based security - authentication of users; system integrity; confidentiality of communication; availability of business service; and non-repudiation of transactions - are covered in detail. Throughout the book the major trends, challenges and applications of e-security are presented, with emphasis on public key infrastructure (PKI) systems, biometric-based security systems, trust management systems, and the e-service paradigm. Intrusion detection technologies, virtual private networks (VPNs), malware, and risk management are also discussed. Technically oriented with many practical examples, this book is suitable for practitioners in network security, as well as graduate students and researchers in telecommunications and computer science.
Are you a Business Analyst who struggles to explain what it is that you do? Or do you work with BAs and not quite get why they're there? This book offers a simple explanation of this hugely valuable role, why it is that they're so critical to successful business change and why all types of organisations should be benefiting from the unique skillset of a BA.
Cooperative Computer-Aided Authoring and Learning: A Systems Approach describes in detail a practical system for computer assisted authoring and learning. Drawing from the experiences gained during the Nestor project, jointly run between the Universities of Karlsruhe, Kaiserslautern and Freiburg and the Digital Equipment Corp. Center for Research and Advanced Development, the book presents a concrete example of new concepts in the domain of computer-aided authoring and learning.
