• Une photo de famille aussi douce qu'impitoyable.
    Sur la terrasse, la table est dressée. Le repas est prêt. Esther attend ses enfants pour le déjeuner. Depuis quelques années, ça n'arrive plus jamais. Vanessa, la petite dernière, est toujours en vadrouille. Bruno et Alexandre refusent de se parler. Carole, l'aînée, préfère se tenir à distance. Et Reza, leur père, reste indifférent. Mais l'heure tourne et rien ne se passe comme prévu ; certains sont en retard, d'autres ne viendront pas. Les malentendus, les anciennes querelles et les blessures toujours vives se ravivent avec fracas. Les jours heureux aussi, comme autant de petits noeuds qu'Esther tente, une dernière fois, de resserrer autour de sa famille.

  • Partant d'un constat sur le comportement des musiciens congolais depuis quelques années, l'auteur se demande si la musique congolaise peut contribuer à l'éducation, mieux à l'éducation à la citoyenneté. C'est ainsi qu'il fait l'historique de la musique congolaise, de la traditionnelle à la moderne, tout en établissant des convergences et divergences entre la musique chrétienne et la musique profane. Il trouve que la musique a une noble mission bafouée ou banalisée par les musiciens congolais. Ainsi a-t-il initié une éthique du musicien.

  • Décrire nos maux nous révèle et nos mots ne décrivent pas seulement une souffrance, ils témoignent aussi de notre culture, de notre identité profonde. Médecin, fin connaisseur des langues et cultures de l'est de l'Europe et du Proche-Orient, l'auteur exerce dans l'un desquartiers où la population est la plus diversifiée de la capitale. Il est témoin privilégié des origines et du langage de ces malades venus d'ailleurs. La rencontre avec un autre médecin, spécialiste des aspects économiques et socioculturels de la santé, est à l'origine de cette réflexion.

  • The animal world is full of mysteries. Why do dogs slurp from their drinking bowls while cats lap up water with a delicate flick of the tongue? How does a tiny turtle hatchling from Florida circle the entire northern Atlantic before returning to the very beach where it hatched? And how can a Komodo dragon kill a water buffalo with a bite only as strong as a domestic cat's? These puzzles ? and many more besides ? are all explained by physics. From heat and light to electricity and magnetism, Furry Logic unveils the ways that more than 30 animals exploit physics to eat, drink, mate and dodge death in their daily battle for survival. Along the way, science journalists Matin Durrani and Liz Kalaugher introduce the great physicists whose discoveries helped us understand the animal world, as well as the animal experts of today who are scouring the planet to find and study the animals that seem to push the laws of physics to the limit. Presenting mind-bending physics principles in a simple and engaging way, Furry Logic will appeal both to animal lovers and to those curious to see how physics crops up in the natural world. It's more of a 'howdunit' than a whodunit, though you're unlikely to guess some of the answers.

  • This book is written as a very concise introduction for students taking a first course in communication systems. It provides the reader with fundamentals of digital communication systems and disseminates the essentials needed for the understanding of wire and wireless communication systems for Electrical Engineers. It covers important topics right from the beginning of the subject which communication engineers must understand. Example problems in each chapter will help them in understanding the materials well. The study of data networking will include multiple access, reliable packet transmission, routing and protocols of the internet. The concepts taught in class will be discussed in the context of aerospace communication systems: aircraft communications, satellite communications. The book includes example problems in each chapter to help the reader in understanding the materials well.

  • This book presents cutting-edge research contributions that address various aspects of network design, optimization, implementation, and application of cognitive radio technologies. It demonstrates how to make better utilization of the available spectrum, cognitive radios and spectrum access to achieve effective spectrum sharing between licensed and unlicensed users. The book provides academics and researchers essential information on current developments and future trends in cognitive radios for possible integration with the upcoming 5G networks. In addition, it includes a brief introduction to cognitive radio networks for newcomers to the field.

  • This book introduces the reader to the MIMO-OFDM system, in Rayleigh frequency selective-channels. Orthogonal frequency division multiplexing (OFDM) has been adopted in the wireless local-area network standards IEEE 802.11a due to its high spectral efficiency and ability to deal with frequency selective fading. The combination of OFDM with spectral efficient multiple antenna techniques makes the OFDM a good candidate to overcome the frequency selective problems.

  • This book gathers state-of-the-art research contributions written by academics and researchers, which address emerging trends in system design and implementation for the Internet of Things (IoT), and discuss how to promote IoT technologies and applications.

    The book is chiefly intended for researchers and academics who want to get caught up with the latest trends in enabling technologies for IoT and related applications and services. However, it also includes chapters on the fundamentals of IoT, offering essential orientation for general readers.
