Abstract

In this work new methods and criteria for the analysis of Ultra Wideband (UWB) components and systems are introduced. This permit to have a deeper insight into the component characteristics like signal distortion, ringing and dispersion, introduced by the non-ideal behavior of the UWB components over the wide frequency band. The developed analyses are the basis for correction and optimization strategies for the features of the UWB components and systems, compensating for their non-idealities.

Abstract

"Thirty years after Chomsky and Herman elaborated the Propaganda Model this title aims to introduce a new generation of readers to it. It presents cutting-edge research demonstrating the model’s general validity as well as new attempts – in the light of digital media and 21st century politics – to critically update, expand, and refine it.
International researchers thus analyse the continuities and new developments in media
Environments throughout various regions of the world. Part I addresses the theoretical and methodological dimensions of the PM beginning with an interview with Edward Herman on the model itself. Part II reflects on propaganda as a concept and practice within new mediated digital communications systems and interfaces. Applications of the Propaganda Model are featured in Part III notably new forms of media and content not previously analysed within it: the entertainment industries through the analysis of television, professional sports, Hollywood movies and videogames using quantitative and qualitative research methods. The last section presents case studies of corporate media and reporting practices as reflections of elite power. An extensive re-visioning of the PM this book concludes by identifying the fundamental dimensions of the model, the key modifications and expansions that are suggested—such as the inclusion of new filters—whilst assessing the model’s overall value for conducting research in different geographical contexts and media systems and products."

Abstract

The roll-out of a high-performance DC electric vehicle supply equipment infrastructure is a key factor for the success of electric mobility. This work enhances existing control schemes for active rectifiers utilized in charging systems, resulting in minimized requirements for network connection. In addition, active power quality filtering is achieved. The proposed control concept is experimentally validated using a fast charger system.

Abstract

Remixers recombine copyright-protected audiovisual material and distribute it via hosting platforms. To what extent does copyright law allow remixing and what is the impact of platforms' policies and filtering mechanisms for user uploads? Henrike Maier employs a comparative legal approach and focuses on the role of creative users' fundamental rights to investigate these questions.

Abstract

This Special Issue contains a series of excellent research works on telecommunications and signal processing, selected from the 2018 41st International Conference on Telecommunications and Signal Processing (TSP) which was held on July 4–6, 2018, in Athens, Greece. The conference was organized in cooperation with the IEEE Region 8 (Europe, Middle East, and Africa), IEEE Greece Section, IEEE Czechoslovakia Section, and IEEE Czechoslovakia Section SP/CAS/COM Joint Chapter by seventeen universities from the Czech Republic, Hungary, Turkey, Taiwan, Japan, Slovak Republic, Spain, Bulgaria, France, Slovenia, Croatia, and Poland, for academics, researchers, and developers, and serves as a premier international forum for the annual exchange and promotion of the latest advances in telecommunication technology and signal processing. The aim of the conference is to bring together both novice and experienced scientists, developers, and specialists, to meet new colleagues, collect new ideas, and establish new cooperation between research groups from universities, research centers, and private sectors worldwide. This collection of 10 papers is highly recommended for researchers, and believed to be interesting, inspiring, and motivating for readers in their further research.

Abstract

The possibility of guiding light in air has fascinated optical scientists and engineers since the dawn of optical fiber technology. In the last few years, hollow core optical fibers have been attracting the attention of an expanding worldwide research community, furthering the design, fabrication and device implementation of specialty optical fibers. Hollow core optical fibers are entering almost any specific application field of optics from medicine to security; from telecommunication to industrial processing; from instrumentation to biology. In parallel to the increased number of applications, major advances are still being made on the optimization of hollow core fiber designs and on the study of its underlying guiding properties, as well as in the use of different materials and fabrication techniques, which, in turn, are providing even more ways of exploitation of this technology and new technical challenges. This Special Issue of Fibers rides the wave of this increasing interest in the field of hollow core optical fibers by providing an overview of the recent progress in this field as well as an updated and indicative sample of current research activities worldwide.

Abstract

This book presents a selection of papers representing current research on using field programmable gate arrays (FPGAs) for realising image processing algorithms. These papers are reprints of papers selected for a Special Issue of the Journal of Imaging on image processing using FPGAs. A diverse range of topics is covered, including parallel soft processors, memory management, image filters, segmentation, clustering, image analysis, and image compression. Applications include traffic sign recognition for autonomous driving, cell detection for histopathology, and video compression. Collectively, they represent the current state-of-the-art on image processing using FPGAs.
