Taschenbuch. Zustand: Neu. Neuware - A decade ago, the corporate world viewed grid computing as a curiosity. Today, it views it as an opportunity--a chance to reduce costs, improve performance, fund new projects, and take advantage of under-utilized capacity. The engineering behind this transformation has been amply documented. Until now, however, little has been written to prepare managers, executives, and other decision-makers to implement grid computing in a sensible and effective way.Grid Computing: The Savvy Manager's Guide examines the technology from a rigorous business perspective, equipping you with the practical knowledge you need to assess your options and determine what grid computing approach is right for your enterprise. This book is heavy on real-world experience, distilling from a rich assortment of case studies the best practices currently at work in a variety of industries. Always attentive to grid computing's many competitive advantages, it is also realistic about the challenges of selling the idea to staff and making it a part of your company's culture. Sketches the history of grid computing, showing how it made the leap from academia to business. Examines the criteria you'll need to meet to make your network 'grid-enabled.' Explains how a grid-based solution can be made to meet key organizational requirements, including security, scheduling, data storage, and fault-tolerance. Surveys the approaches currently available and helps you choose the one that will best meet your needs, both now and in the future. Focuses heavily on the competitive advantages you can reap from grid computing, and provides advice on convincing your organization to adopt grid computing and making a successful transition.

Taschenbuch. Zustand: Neu. Neuware - Current Sources and Voltage References provides fixed, well-regulated levels of current or voltage within a circuit. These are two of the most important 'building blocks ' of analog circuits, and are typically used in creating most analog IC designs. Part 1 shows the reader how current sources are created, how they can be optimized, and how they can be utilized by the OEM circuit designer. The book serves as a 'must-have reference for the successful development of precision circuit applications. It shows practical examples using either BJTs, FETs, precision op amps, or even matched CMOS arrays being used to create highly accurate current source designs, ranging from nanoAmps to Amps. In each chapter the most important characteristics of the particular semiconductor type being studied are carefully reviewed. This not only serves as a helpful refresher for experienced engineers, but also as a good foundation for all EE student coursework, and includes device models and relevant equations.Part 2 focuses on semiconductor voltage references, from their design to their various practical enhancements. It ranges from the simple Zener diode to today's most advanced topologies, including Analog Devices' XFET® and Intersil's FGA(TM) (invented while this book was being written). Over 300 applications and circuit diagrams are shown throughout this easy-to-read, practical reference book.
