Node.js ist eine auf JavaScript basierende serverseitige Programmierumgebung f�r die Applikationsentwicklung. Schwerpunkt sind meist Webapplikationen, allerdings ist Node keineswegs darauf begrenzt. Zusammen mit der Paketverwaltung Node Package Manager (npm) entstand eine leistungsf�hige Umgebung zur plattformunabh�ngigen Programmierung. Dieses Werk zeigt die Bausteine, die Sie ben�tigen, um eine Web-Applikation mit Node zu erstellen. Dazu geh�rt neben Node selbst das Middleware-Framework Express und die Vorlagensprache Pug (ehemals JADE). Dieses Werk geht auf Node in seiner elementarsten Form ein, zeigt die Programmierung einer einfachen Applikationsstruktur f�r eine Webanwendung und stellt die wichtigsten Node-Module vor, angelehnt an die offizielle Dokumentation. Im selben Stil wird Express und Pug gezeigt, damit der Leser einen schnellen �berblick �ber die Grundlagen und M�glichkeiten bekommt. Der Teil der Anwendung, der clientseitig erforderlich ist, findet dagegen keine Beachtung. In den gezeigten Beispielen wird nur HTML benutzt.Dieses Buch ist ein Sammelband, dessen Inhalt auch einzeln unter den Titeln "Einf�hrung in node.js", "express - Middleware f�r node.js" und "Pug - Die Template-Engine f�r node.js" erh�ltlich ist. Der hier vorliegende Sammelband wurde �berarbeitet und an aktuelle Versionen angepasst. Diese Ausgabe ist aktuell Ende 2016.

Schon die erste Auflage des englischen Lehrbuchs 'Fundamentals of Photonics' zeichnete sich durch seine ausgewogene Mischung von Theorie und Praxis aus, und deckte in detaillierter Darstellung die grundlegenden Theorien des Lichts ab. Es umfasste sowohl die Themen Strahlenoptik, Wellenoptik, elektromagnetische Optik, Photonenoptik, sowie die Wechselwirkung von Licht und Materie, als auch die Theorie der optischen Eigenschaften von Halbleitern. Die Photonik-Technologie hat eine rasante Entwicklung genommen seit der Publikation der ersten Ausgabe von 'Fundamentals of Photonics' vor 15 Jahren. Die nun vorliegende Zweite Auflage des Marksteins auf dem Gebiet der Photonik trägt mit zwei neuen und zusätzlichen Kapiteln den neuesten technologischen Fortschritten Rechnung: Photonische Kristalle sowie Ultrakurzpuls-Optik. Zudem wurden alle Kapitel gründlich überarbeitet und viele Abschnitte hinzugefügt, so z.B. über Laguerre-Gauss Strahlen, die Sellmeier-Gleichung, Photonenkristall-Wellenleiter, photonische Kristallfasern, Mikrosphären-Resonatoren, Optische Kohärenz Tomographie, Bahndrehimpuls des Photons, Bohrsche Theorie, Raman-Verstärker, rauscharme Avalanche-Photodioden, Abstimmkurven und Dispersions-Management.

Fibre-to-the-Home networks constitute a fundamental telecom segment with the required potential to match the huge capacity of transport networks with the new user communication demands. Huge investments in access network infrastructure are expected for the next decade, with many initiatives already launched around the globe recently, driven by the new broadband service demands and the necessity by operators to deploy a future-proof infrastructure in the field. Dense FTTH Passive Optical Networks (PONs) is a cost-efficient way to build fibre access, and international standards (G/E-PON) have been already launched, leading to new set of telecom products for mass deployment. However, these systems only make use of less than 1% of the optical bandwidth; thus, relevant research is taking place to maximize the capacity of these systems, with the latest opto-electronic technologies, demonstrating that the huge bandwidth available through the fibre access can be exploited in a cost-efficient and reliable manner. Next-Generation FTTH Passive Optical Networks gathers and analyzes the most relevant techniques developed recently on technologies for the next generation FTTH networks, trying to answer the question: what’s after G/E-PONs?

Spätestens mit der Novelle des Energiewirtschaftsgesetzes (EnWG) des Jahres 2011 wurde der schrittweise Austausch der bekannten analogen Messgeräte zur Erfassung des Verbrauchs von Strom, Gas, Wasser und Wärme durch elektronische Zähler, sogenannte Smart Meter, eingeleitet. Dieser als Rollout bezeichnete Austausch der Messinfrastruktur inklusive deren Einbindung in die Geschäftsprozesse von Versorgungsunternehmen wird in den kommenden Jahren eines der beherrschenden Aufgabenstellungen der deutschen Energiewirtschaft sein. Wie kann ein flächendeckender Rollout ablaufen? Welche Besonderheiten sind zu berücksichtigen und wo liegen die Risiken? Auf diese und weitere Fragestellungen geben Autoren aus Wissenschaft und Praxis in diesem Buch praxiserprobte Antworten. Eine wichtige Rolle spielen insbesondere Erkenntnisse aus realen Rollout-Piloten, die dem Leser als Hilfestellung und Anregung für eigene Vorhaben dienen können.

Everybody wants more from telecommunications. Service and equipment providers are queuing to meet these needs. This book is a result of ISSLS 91, a forum for reconciling supply and demand. The overall theme of the conference was Moving to the User , with sub-themes of Communication in Business, Secure and Dependable Services, Operations and Management, and Access Architectures and Technologies. ISSLS has for many years been dominated by the impact of network digitalization as it spreads into the local access network, particularly in the form of ISDN. The technology in this area has been maturing and the new challenge is to identify the ways digitalization can be exploited, both by the users for new applications, and by the network provider for making networks more manageable, resilient, flexible and cost-effective. Radio coupled with digital processing and control is now a major force, giving the opportunity for wireless operation on scales varying between the cordless telephone and the rapid provision of services in rural areas. For many purposes, the major challenge of radio lies in living with its limited bandwidth. This is not the case with optical fibres, where bandwidths generally exceed all needs, and the challenge lies in launching and receiving signals in a cost-effective way, and by sharing between multiple users. At ISSLS 88 proposals were made for passive optical networks (PONs). Since then much study has been put into these and other techniques and the progress and problems are reported in this book.
