The Palm theory and the Loynes theory of stationary systems are the two pillars of the modern approach to queuing. This book, presenting the mathematical foundations of the theory of stationary queuing systems, contains a thorough treatment of both of these. This approach helps to clarify the picture, in that it separates the task of obtaining the key system formulas from that of proving convergence to a stationary state and computing its law. The theory is constantly illustrated by classical results and models: Pollaczek-Khintchin and Tacacs formulas, Jackson and Gordon-Newell networks, multiserver queues, blocking queues, loss systems etc., but it also contains recent and significant examples, where the tools developed turn out to be indispensable. Several other mathematical tools which are useful within this approach are also presented, such as the martingale calculus for point processes, or stochastic ordering for stationary recurrences. This thoroughly revised second edition contains substantial additions - in particular, exercises and their solutions - rendering this now classic reference suitable for use as a textbook.

Affirmative legislative action in many countries now requires that public spaces and services be made accessible to disabled people. Although this is often interpreted as access for people with mobility impairments, such legislation also covers those who are hearing or vision impaired. In these cases, it is often the provision of advanced technological devices and aids which enables people with sensory impairments to enjoy the theatre, cinema or a public meeting to the full. Assistive Technology for the Hearin-impaired, Deaf and Deafblind shows the student of rehabilitation technology how this growing technical provision can be used to support those with varying reductions in auditory ability and the deafblind in modern society. Features: instruction in the physiology of the ear together with methods of measurement of hearing levels and loss; the principles of electrical engineering used in assistive technology for the hearing impaired; description and demonstration of electrical engineering used in hearing aids and other communications enhancement technologies; explanation of many devices designed for every-day living in terms of generic electrical engineering; sections of practical projects and investigations which will give the reader ideas for student work and for self teaching. The contributors are internationally recognised experts from the fields of audiology, electrical engineering, signal processing, telephony and assistive technology. Their combined expertise makes Assistive Technology for the Hearing-impaired, Deaf and Deafblind an excellent text for advanced students in assistive and rehabilitation technology and to professional engineers and medics working in assistive technology who wish to maintain an up-to-date knowledge of current engineering advances.

A collection of lectures on a variety of modern subjects in wave scattering, including fundamental issues in mesoscopic physics and radiative transfer, recent hot topics such as random lasers, liquid crystals, lefthanded materials and time-reversal, as well as modern applications in imaging and communication. There is a strong emphasis on the interdisciplinary aspects of wave propagation, including light and microwaves, acoustic and elastic waves, propagating in a variety of "complex" materials (liquid crystals, media with gain, natural media, magneto-optical media, photonic and phononic materials, etc.). It addresses many different items in contemporary research: mesoscopic fluctuations, localization, radiative transfer, symmetry aspects, and time-reversal. It also discusses new (potential) applications in telecommunication, soft matter and imaging.
