Africa 2.0 provides an important history of how two technologies - mobile calling and internet - were made available to millions of sub-Saharan Africans, and the impact they have had on their lives. The book deals with the political challenges of liberalisation and privatisation that needed to be in place in order for these technologies to be built. It analyses how the mobile phone fundamentally changed communications in sub-Saharan Africa and the ways Africans have made these technologies part of their lives, opening up a very different future. The book offers a critical examination of the impact these technologies have had on development practices, and the key role development actors played in accelerating regulatory reform, fibre roll-out and mobile money. Southwood shows how corruption in the industry is a prism through which patronage relationships in government can be understood, and argues that the arrival of a start-up ecosystem in the region has the potential to change this. A vital overview of the changes of the last three decades, Africa 2.0 examines the transformative effects of mobile and internet technologies, and the very different future they have opened out for sub-Saharan Africa. -- .

This book shows designers how to ensure signal integrity and control noise in high-speed digital systems - particularly important in a Pentium-paced environment where functional logic design is no longer separable from electrical and mechanical design. Highlighting TTL, CMOS, and BiCMOS logic applications in a single source, Signal and Power Integrity in Digital Systems provides a practical solutions-oriented approach to a wide variety of relevant interconnection and timing issues. Special features include noise tolerant logic architectures; power distribution techniques that reduce noise; clock distribution techniques that ensure clock signal quality; signal interconnection techniques that reduce crosstalk, signal loading, and transmission-line effects; how to get optimum performance from high-speed memory devices; and system application tips for high-speed PALs, PLAs, FIFOs, and ASICs. Designers will also appreciate the practical engineering approximations provided for the calculation of design parameters along with illustrations and numerous tables usable for quick reference and comparison of characteristics. It's a book every digital designer should have - engineers involved in the design of computers, peripherals, signal processors, and control and communications equipment, as well as young engineers facing their first designs using high-speed logic devices.

A major challenge in grid computing remains the application software development for this new kind of infrastructure. Grid application programmers have to take into account several complicated aspects: distribution of data and computations, parallel computations on different sites and processors, heterogeneity of the involved computers, load balancing, etc. Grid programmers thus demand novel programming methodologies that abstract over such technical details while preserving the beneficial features of modern grid middleware. For this purpose, the authors introduce Higher-Order Components (HOCs). HOCs implement generic parallel/distributed processing patterns, together with the required middleware support, and they are offered to users via a high-level service interface. Users only have to provide the application-specific pieces of their programs as parameters, while low-level implementation details, such as the transfer of data across the grid, are handled by the HOCs. HOCs were developed within the CoreGRID European Network of Excellence and have become an optional extension of the popular Globus middleware. The book provides the reader with hands-on experience, describing a broad collection of example applications from various fields of science and engineering, including biology, physics, etc. The Java code for these examples is provided online, complementing the book. The expected application performance is studied and reported for extensive performance experiments on different testbeds, including grids with worldwide distribution. The book is targeted at graduate students, advanced professionals, and researchers in both academia and industry. Readers can raise their level of knowledge about methodologies for programming contemporary parallel and distributed systems, and, furthermore, they can gain practical experience in using distributed software. Practical examples show how the complementary online material can easily be adopted in various new projects.

The motivation for this book stems from an early exposure to the book Ap plied Mechanics by John Perry. Professor Perry strove to encourage his readers to understand the applications and use of mathematics in engineering with out insisting that they become immersed in pure mathematics. The following text uses this approach to the application of telecommunications switching. Readers wishing to study the derivation and proof of formulas will be able to do so using relevant references. The existence of low-cost programmable calculators frees practicing engineers from much laborious calculation, allowing more time for creative design and application of the art. The reader should not need to be able to derive formulas in order to apply them just as, to quote Professor Perry, "He should not have to be able to design a watch in order to tell time ... The material for this book has been drawn from my own experience in the field. Inevitably, however, I have used CCITT and Bell System publications for references and in some cases quotation, and I gratefully acknowledge permission for their use. I am also grateful to Stromberg Carlson Corporation for their earlier encour agement and support without which this book would not have been possible. Thanks are also due to Fred Hadfield for his advice and assistance in the preparation of the many figures and to my wife Ada for her support and patience as I pursued the demanding but interesting task of producing the text."

'Data acquisition' is concerned with taking one or more analogue signals and converting them to digital form with sufficient accu racy and speed to be ready for processing by a computer. The increasing use of computers makes this an expanding field, and it is important that the conversion process is done correctly because information lost at this stage can never be regained, no matter how good the computation. The old saying - garbage in, garbage out - is very relevant to data acquisition, and so every part of the book contains a discussion of errors: where do they come from, how large are they, and what can be done to reduce them? The book aims to treat the data acquisition process in depth with less detailed chapters on the fundamental principles of measure ment, sensors and signal conditioning. There is also a chapter on software packages, which are becoming increasingly popular. This is such a rapidly changing topic that any review of available pro grams is bound to be out of date before the book reaches the read ers. For this reason, I have described the data handling which is available in various types of program and left it to the reader to select from whatever is on the market at the time."

In his paper Theory of Communication [Gab46], D. Gabor proposed the use of a family of functions obtained from one Gaussian by time-and frequency shifts. Each of these is well concentrated in time and frequency; together they are meant to constitute a complete collection of building blocks into which more complicated time-depending functions can be decomposed. The application to communication proposed by Gabor was to send the coeffi cients of the decomposition into this family of a signal, rather than the signal itself. This remained a proposal-as far as I know there were no seri ous attempts to implement it for communication purposes in practice, and in fact, at the critical time-frequency density proposed originally, there is a mathematical obstruction; as was understood later, the family of shifted and modulated Gaussians spans the space of square integrable functions [BBGK71, Per71] (it even has one function to spare [BGZ75] . . . ) but it does not constitute what we now call a frame, leading to numerical insta bilities. The Balian-Low theorem (about which the reader can find more in some of the contributions in this book) and its extensions showed that a similar mishap occurs if the Gaussian is replaced by any other function that is "reasonably" smooth and localized. One is thus led naturally to considering a higher time-frequency density.

Lectori Salutem! This is another book - among the myriads - dealing with wireless communications. The reader might be aware: this topic is really among bestsellers in technology - bestsellers in technology itself and that in technical literature. Communications is one of the leading techniques in information society and mobile/wireless communications is one among the (maybe not more than two with optics the second) leading techniques in communications. Development of wireless communications was and is really spec- cular in the last decade of the 20th and first decade of the 21st century. Such topics as MIMO, wireless networking, security in the technological field, new business models in the service providing field, various applications in the users' side, to mention a few only, were undergoing an unprecedented evolution. So it is not surprising that the number of conferences and the number of books in this field grows and grows, in a nearly unbounded way.
