Explores the increasingly intimate relationship between China and wireless technology, taking the wave as a central concept In the twenty-first century city, wireless waves constitute an imperceptible, immersive, all-encompassing environment. Nowhere is this more so than in China, where a hyperdense network of mobile media has restructured daily life. Anna Greenspan re-imagines the relationship between China and wirelessness by synthesizing contemporary media theory with modern Chinese thought. It focuses specifically on the work of three critical figures: Tan Sitong 譚嗣同 (1865-1898), Xiong Shili 熊十力 (1885-1968) and Mou Zongsan 牟宗三 (1909-1995). Anna Greenspan is Assistant Professor of Global Contemporary Media at NYU Shanghai.

Dieses Lehrbuch ist eine einführende Darstellung der Übertragung digitaler Signale über gestörte Kanäle. Schwerpunkt ist die physikalisch-anschauliche und zugleich mathematisch-fundierte Erklärung der Übertragung im Basisband. Dazu werden notwendige Grundlagen der Signal- und Systemtheorie rekapituliert und funktionale Abhängigkeiten bei der Basisbandübertragung herausgearbeitet, um ein Verständnis der grundlegenden Probleme bei der Nachrichtenübertragung zu ermöglichen. Als wichtiger Übertragungskanal wird das Kupferkabel betrachtet und seine übertragungstechnischen Eigenschaften werden mit klassischen elektrotechnischen und systemtheoretischen Methoden beschrieben. Die zuvor beschriebenen Basisbandverfahren werden zur Übertragung über den linear verzerrenden Kanal eines Kupferkabels angewendet und Möglichkeiten der Filterung und Entzerrung erläutert. Dem einführenden Charakter des Lehrbuches entsprechend werden jeweils ausführliche Herleitungen angegeben sowie numerische Beispiele und eine Vielzahl von Abbildungen verwendet.

Die Ursprünge von IoT gehen von Kevin Ashton zurück bis zu den RFID-Sensoren in den 70er Jahren. Industrie 4.0 basiert ebenfalls auf den Ideen von IoT mit dem wesentlichen Punkt der globalen Internetkommunikation: Wer IoT sagt, meint Industrie 4.0 und umgekehrt. IoT ist von Industrie 4.0 nicht mehr zu trennen. Die Geschichte und die Zusammenhänge von IoT und Industrie 4.0 werden auf anschauliche Weise anhand von Beispielen erklärt, angefangen vom Ethernet TCP/IP, über die generelle Automatisierungsstrategie bis hin zu den grundlegenden vertikalen und horizontalen Kommunikationsprotokollen, bei denen heute OPC UA und Cloud Computing eine tragende Rolle zukommt.Den kostenlosen Zugang zum Online-Kurs finden Sie direkt im Buch.

In modern data analysis, massive measurements from a network require novel signal processing techniques, which are expected to be adapted to the network topology, have distributed implementation, and are flexible enough for various applications. Graph signal processing (GSP) theories and techniques are geared towards these goals. GSP has seen rapid developments in recent years. Since its introduction around ten years ago, we have seen numerous new ideas and practical applications related to the field. In this monograph, an overview of recent advances in generalizing GSP is presented, with a focus on the extension to high-dimensional spaces, models, and structures. Alongside new frameworks proposed to tackle such problems, many new mathematical tools are introduced. In the first part of the monograph, traditional GSP is reviewed, challenges that it faces are highlighted, and efforts in overcoming such challenges are motivated. These efforts then become the theme for the rest of the publication. Included are the generalization of GSP to high dimensional vertex signal spaces, the theory of random shift operators and the wide-sense stationary (WSS) statistical signal models, and the treatment of high dimensionality in graph structures and generalized graph-like structures. The monograph concludes with an outline of possible future directions.
