The Digital City


Book Description

Shows how digital media connects people to their lived environments Every day, millions of people turn to small handheld screens to search for their destinations and to seek recommendations for places to visit. They may share texts or images of themselves and these places en route or after their journey is complete. We don’t consciously reflect on these activities and probably don’t associate these practices with constructing a sense of place. Critics have argued that digital media alienates users from space and place, but this book argues that the exact opposite is true: that we habitually use digital technologies to re-embed ourselves within urban environments. The Digital City advocates for the need to rethink our everyday interactions with digital infrastructures, navigation technologies, and social media as we move through the world. Drawing on five case studies from global and mid-sized cities to illustrate the concept of “re-placeing,” Germaine R. Halegoua shows how different populations employ urban broadband networks, social and locative media platforms, digital navigation, smart cities, and creative placemaking initiatives to turn urban spaces into places with deep meanings and emotional attachments. Through timely narratives of everyday urban life, Halegoua argues that people use digital media to create a unique sense of place within rapidly changing urban environments and that a sense of place is integral to understanding contemporary relationships with digital media.




Fundamentals of Optical Fiber Sensors


Book Description

This book describes the latest development in optical fiber devices, and their applications to sensor technology. Optical fiber sensors, an important application of the optical fiber, have experienced fast development, and attracted wide attentions in basic science as well as in practical applications. Sensing is often likened to human sense organs. Optical fiber can not only transport information acquired by sensors at high speed and large volume, but also can play the roles of sensing element itself. Compared with electric and other types of sensors, fiber sensor technology has unique merits. It has advantages over conventional bulky optic sensors, such as combination of sensing and signal transportation, smaller size, and possibility of building distributed systems. Fiber sensor technology has been used in various areas of industry, transportation, communication, security and defense, as well as daily life. Its importance has been growing with the advancement of the technology and the expansion of the scope of its application, a growth this book fully describes.







Optical Communication


Book Description

Optical communication is very much useful in telecommunication systems, data processing and networking. It consists of a transmitter that encodes a message into an optical signal, a channel that carries the signal to its desired destination, and a receiver that reproduces the message from the received optical signal. It presents up to date results on communication systems, along with the explanations of their relevance, from leading researchers in this field. The chapters cover general concepts of optical communication, components, systems, networks, signal processing and MIMO systems. In recent years, optical components and other enhanced signal processing functions are also considered in depth for optical communications systems. The researcher has also concentrated on optical devices, networking, signal processing, and MIMO systems and other enhanced functions for optical communication. This book is targeted at research, development and design engineers from the teams in manufacturing industry, academia and telecommunication industries.
