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.
During the past three decades since the publication of the last volume on the magnetic susceptibilities of co-ordination and organometallic transition metal compounds thousands of new paramagnetic compounds of striking diversity and novelty have appeared. The present volume on the magnetic properties of paramagnetic compounds covers 1663 references published between 1985 and 1991. After an introduction into the theoretical aspects of the paramagnetic susceptibility, the data tables are providing experimental values for susceptibility, effective paramagnetic moment, and paramagnetic Curie constant. Where available the tempereature dependence of the magnetic susceptibility is given in figures. The compounds are listed under their central metal ion (transition metal, lanthanide or actinide) of definite, or mixed, oxidation state. The substances include simple compounds, co-ordination compounds (N-ligands, O-ligands, S-ligands, etc.), organometallic compounds, homo- and hetero-multimetallic derivatives, clusters, polymers. Finally, data for organic radicals are given.
The book offers a comprehensive report on the design and optimization of a thermochemical heat storage system for use in buildings. It combines theoretical and experimental work, with a special emphasis on model-based methods. It describes the numerical modeling of the heat exchanger, which allows recovery of about two thirds of the waste heat from both solar and thermal energy. The book also provides readers with a snapshot of current research on thermochemical storage systems, and an in-depth review of the most important concepts and methods in thermal management modeling. It represents a valuable resource for students, engineers and researchers interested in thermal energy storage processes, as well as for those dealing with modeling and 3D simulations in the field of energy and process engineering.
