Contemporary distributed file systems are monolithic and only support single file abstractions. Nowadays, as Sai-Lai Lo explains, network storage devices have to accommodate new information media such as digital audio and video, with data radically different from the traditional text and binary code that contemporary file systems are optimized for. In this book, the author shows how, by combining new and traditional media, information can be recorded and presented in the most suitable way, and the value of a piece of information can be further enhanced by linking together related pieces. However, composite data and cross-reference between data items raise a number of system issues that have not been addressed properly before. Lo defines a new multiservice storage architecture that meets the needs of existing and emerging applications and can support multiple file abstractions. He also explores a number of related design issues. Researchers in the areas of distributed systems, network multimedia and network storage services will enjoy this book.
?Limited potential of financial, organizational, human and technology resources doesn't provide SMEs sufficient opportunities to access information and knowledge necessary in competition. Observing the methods and tools used by large companies, this book studies the conditions under which it would be possible to provide support to SMEs at a lower cost and with greater methodological and organizational backing. The author presents the proposed solution, Benchmarking Collaborative Network, which would provide SMEs access to information about their level of competitiveness, the key areas for the creation of competitive advantage and the activities required to achieve this advantage.
The potential use of hydrogen as a clean and renewable fuel resource has generated significant attention in recent years, especially given the rapidly increasing demand for energy sources and the dwindling availability of fossil fuels. Hydrogen is an ?ideal fuel? in several ways. Its only byproduct of consumption is water; it is the most abundant element in the universe; and it is available at low cost. Hydrogen generation is possible via a number of possible chemical processes, to separate the hydrogen from its bond with atoms such as carbon, nitrogen, and oxygen.
In this book, the authors provide the scientific foundations for established and innovative methods of hydrogen extraction; outline solutions for its storage; and illustrate its applications in the fields of petroleum, chemical, metallurgical, physics, and manufacturing.
