Available in PDF, EPUB and Kindle. Book excerpt: The content of this book is the result of the work and the experiences of an interdisciplinary and strictly European group of researchers who have attempted to give birth to a new fibre communication network concept by exploiting the potential benefits of optical coherent transmission. The run towards this ambitious goal started in 1985 on the basis of the ESPRIT program incentives by an "ad hoc" consortium of industrial partners and research institutions. The first three years were dedicated to a feasibility study carried out by a reduced number of "pioneers". In 1989 the team was extended to eleven partners. There was already clear evidence of the increasing interest in Europe in exploring the actual limits of optical fibre coherent systems; the project had innovative and very advanced features that were gradually refined by incorporating the latest technological developments to which it has directly contributed. The main objective of the project targeted the development of the necessary building blocks to show experimentally the performance and the flexibility built into the proposed concept of multi-channel ultra-wideband network. The system concept developed within this project associates optical frequency division multiplexing with a suitable network architecture and management techniques to allow very high flexibility and efficiency in handling simultaneous transmission over the network (on each optical frequency) of multiple virtual channels each operating with a wide range of information rates ranging from a fraction of a Mb/s up to a maximum value in excess of 160 Mb/s.

Download or read book Fundamentals of Bidirectional Transmission over a Single Optical Fibre written by M.O. van Deventer and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bidirectional transmission over optical fibre networks may yield a large cost reduction because of the reduction of the network infrastructure by a factor two and the potential cost reduction by an integrated transceiver design. It may also provide a cost-effective way to upgrade distribution networks by adding bidirectional channels. This book is the first to provide a comprehensive overview of bidirectional transmission in optical networks. It handles physical aspects: the behaviour of the fibre itself in bidirectional transmission transmission aspects: the behaviour and design of bidirectional systems and network aspects: the influence of bidirectional transmission on network design. £/LIST£ Practical guidelines are also given for bidirectional system design. Audience:This book is aimed at designers, builders and operators of optical networks, e.g. the manufacturers of optical transmission systems, public-network operators, developers of local-area networks, cable-television operators, etcetera. The intended level of readership is graduate level in physics or electrical engineering.

Download or read book Coherent Optical Communications and Photonic Switching written by Giancarlo Prati and published by Elsevier Publishing Company. This book was released on 1990 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Photonic switching is a term used to describe existing and new photonic devices in conjunction with existing and new electronic devices to realise new or improved switching and networking capabilities. It includes simple mechanically activated optical switches used for network protection switching and network reconfiguration, where an entire optical signal is redirected as a unit. It includes the use of optical interconnections within equipment to facilitate internal high speed and high density interconnects. It includes the use of tunable transmitters and receivers at the core of a high speed packet or circuit switch, with large quantities of electronics providing supporting interface and control functions. In principle it also includes the concept of an all-optical switch whose architecture and component technologies have yet to be invented. In recent years materials and device scientists have been coming together more and more with systems architects to uncover the real opportunity areas for coherent communications and photonic switching.

Download or read book Human Comfort and Security of Information Systems written by Kadamula Varghese and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Commission of the European Union, through its Fourth Framework R&D programme is committed to the development of the Information Society. There is no doubt that there will be many radical changes in all aspects of society caused by the far-reaching impact of continuing advances in information and communi cation technologies. Many of these changes cannot be predicted, but that uncer tainty must not stop us from moving forward. The challenge is to ensure that these technologies are put to use in the most beneficial manner, taking fully into account the rich cultural and linguistic backgrounds within the peoples of Europe. We have a duty to ensure that the ultimate end-users of the technology are involved in the development and application of that technology to help shape its use. Without this active involvement, designers will not understand the individual and organisational requirements of the users, and the users will not understand the impact and applicability of the new technology. Failure on either account will lead to a sense of resentment on the part of the users and a lost opportunity to improve the quality of human life. The work, sponsored by the Human Comfort & Security sub-domain of the ESPRIT programme, has a central part to play in the creation of the Information Society, lying as it does at the interface between the technology and the user.

This book was released on 2013-11-11 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: "User is king" is not a new concept, but it is certainly one that has gathered considerable momentum in the recent years. The driving force are the increasing and relentless pace of competition and the consequent attempts by many companies to keep and improve their marketshare. Since the beginning of ESPRIT Programme in 1984, the Human Computer Interface has been the subject of attention, in terms of technology development and utilisation of those technologies in various applications in the fields of Information Processing Systems, Computer Integrated Manufacturing, and Office and Business Systems. This topic area had been addressed in a number of different perspectives: user modelling, task analysis, cognitive aspects of interaction and assimilation of information, natural language speech and graphics, processing of multisensor information and its presentation, and a wide range of applications in which these technologies are used. In addition to the previous ESPRIT programmes, the specific programme for Information Technology of the European Framework Programme for 1994-1999 has recognised the ever increasing importance of "ease of use" in computer applications. The work programme on Human Comfort and Security is an attempt to address these issues. Its primary objectives are the exploitation of existing knowledge and expertise in usability engineering by integrating methods and tools into coherent toolsets, the generation of improved human computer interface components, demonstrating their application in practice, and widely disseminating the results and promoting the take-up of these technologies.

This book was released on 2012-12-06 with total page 736 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this volume we present the full proceedings of a NATO Advanced Study Institute (ASI) on the theme of the challenge of advanced computing technology to system design methods. This is in fact the second ASI organised by myself and my colleagues in the field of systems reliability; the first was about Electronic Systems Effectiveness and Life Cycle Costing, and the proceed ings were published by the same publisher in 1983, as "Series F (Computer and System Sciences, No. 3)". The first part of the present proceedings concentrates on the development of low-fault and fault-tolerant software. In organising this session I was greatly helped by Mr. John Musa and Professor V. R. Basili. The latter and Or. R. W. Selby open our text with their interesting approach to the problem of data collection and of observation sampling for statistical analysis of software development, software testing strategies and error analysis. The problem of clean room software development is also considered. Next Professor B. Randell discusses recursively structured fault-tolerant distributed computer systems, and bases his approach on a UNIX system example. His aim is to establish that a distributed system should be functionally equivalent to an individual computing system. Or. L. F. Pau considers knowledge engineering techniques applied to fault detection, test generation and maintenance of software. This is illustrated by a variety of examples, such as electronic failure detection, control system testing, analysis of intermittent failures, false alarm reduction and others. Following this Mr. M.
