        Africa 2.0

        Inside a continent’s communications revolution

        by Russell Southwood

        Africa wired up 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 liberalization and privatization that needed to be in place to get these technologies 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. It examines critically the technologies' impact on development practices and the key role development actors played in accelerating things like regulatory reform, fibre roll-out and mobile money. The book considers how corruption in the industry is a prism through which patronage relationships in Government can be understood. The arrival of a start-up ecosystem has the potential to break these relationships and offer a new wave of investment opportunities. The author seeks to go beyond the hype to make a provisional assessment of the kinds of changes that have happened over three decades. It examines how and why these technologies became transformative and seem to have opened out a very different future for Sub-Saharan Africa.

        Practical Guide for Electrical Connectors

        The reference book for device development and the use of electrical connectors

        by Herbert Endres

        This book is a reference work for equipment designers and the use of connectors therein. Every designer and consumer receives answers to questions about design, materials, physical basics, contact surfaces, shielding practices, housing and locking designs and applications. Special chapters highlight the most prominent disciplines for electrical connectors: power electronics on one extreme and high data rates on the other. Finally, various technologies in the production process of electronic assemblies and basic selection criteria for electrical connectors are examined. Even though the market is very large with more than 1000 connector manufacturers, the book gives the user assistance in finding the best connector for the application. From the content: What is a connector The connector components Different termination technologies Insulator materials The contact materials The contact point Various contact surfaces The contact resistance Shielding techniques The locking systems of the connectors Housing and mechanics Why are new connectors being developed? Connectors in power electronics Connector for high data rates Further processing of the connectors in the manufacturing process The connector selection Connector database access in the accompanying online service InfoClick

        Automation technology

        by Norbert Becker

        In this standard work, the automation technology is illustrated from a practical point of view with many examples and numerous pictures. Students of engineering sciences, as well as engineers and technicians in training and professional practice, are able to work independently on the state of the art. The additional or revised chapters on machine safety, safety in process engineering systems, explosion protection and configuration extend the book considerably. For almost every chapter there are comprehension questions and exercises, the solution of which is contained in the appendix. Programming exercises, which are provided free of charge online, make it possible to solve simple automation problems in a practical way. Content: introduction Measuring technology, setting technology controls automation components Practical control technology Examples of overriding requirements for automation components (safety in mechanical engineering and process engineering, explosion protection), Project planning (project implementation, R & I flow diagrams, equipment identification) Annex (ARW measures, adjustment rules, solutions)

        An Introduction to Techniques with SIP

        by Thomas Wübbe

        Since the switch-off of classic telephony technology in 2019, the Session Initiation Protocol (SIP) dominates providers' telephony solutions. This book gives an introduction to this technology. It shows principles as well as the common architecture of Voice over IP with SIP. In addition to differences and changes to the "old" telephone technology, step-by-step methods and requirements for Voice over IP are discussed.Many protocol examples show how SIP works. They help troubleshooting when something does not work. A special practical chapter shows how to do analyses via Wireshark and explains logging in detail. These topics are included: Fundamentals of packet switching and standardization, Internet Protocol (IP) VoIP principle, Architecture of SIP SIP signaling Session Description Protocol (SDP) VoIP and NAT Quality of Service (QoS) Introduction to packet analysis with Wireshark, and Practical exercises.

        Hyperspectral Remote Sensing and Spectral Signature Applications

        by S. Rajendran, S.Aravindran, T.Jeyavel Rajakumar, R. Sivakumar & K.R. Murali Mohan

        Hyperspectral imaging is an emerging modern technique in modern remote sensing that expands and removes capability of multispectral image analysis. It takes advantage of hundreds of continuous spectral channels to uncover materials that usually cannot be resolved by multispectral sensoThis book is a collection of research papers of Indian scientist working in the field of hyperspectral remote sensing and spectral signature applications. This has been organized in a way that all the s are logically connected and can be referred back and the forth one another for more details. The title of hyperspectral remote sensing and spectral signature applications is use to reflect its focus on spectral techniques, i.e. non-literal techniques that are especially designed and developed for hyperspectral imagery rather than multispectral imagery.

        Wired for Sound

        Engineering and Technologies in Sonic Cultures

        by Paul D. Greene

        Wired for Sound is the first anthology to address the role of sound engineering technologies in the shaping of contemporary global music. Wired sound is at the basis of digital audio editing, multi-track recording, and other studio practices that have powerfully impacted the world's music. Distinctions between musicians and engineers increasingly blur, making it possible for people around the globe to imagine new sounds and construct new musical aesthetics.;This collection of 11 essays employs primarily ethnographical, but also historical and psychological, approaches to examine a range of new, technology-intensive musics and musical practices such as: fusions of Indian film-song rhythms, heavy metal, and gamelan in Jakarta; urban Nepali pop which juxtaposes heavy metal, Tibetan Buddhist ritual chant, rap, and Himalayan folksongs; collaborations between Australian aboriginals and sound engineers; the production of "heaviness" in heavy metal music; and the production of the "Austin sound." This anthology is must reading for anyone interested in the global character of contemporary music technology.

        Not all testing is the same. What DIN VDE 0100-600 means for installers of electrical systems, DIN VDE 0105-100 is for operators. But even beyond that, comprehensive and broad knowledge is required for testing electrical systems.Volume 1 provides inspectors, experts, consultants, planners and operators with an overview of the planning principles for electrical systems and the requirements for test personnel. It also deals with the legal principles of the german Energy Industry Act (EnWG), Product Safety Act (ProdSG) and Occupational Health and Safety Act (ArbSchG).
