Apple isn’t just a brand; it’s the world’s most valuable company and creator of the 21st century’s defining product. The iPhone has revolutionized the way we live, work and connect. But Apple is now a victim of its own success, caught in the middle of a new Cold War between two superpowers.

On the brink of bankruptcy in 1996, Apple shifted its operations offshore. By 2003 it was lured to China by the promise of affordable, ubiquitous labour. As the iPod and iPhone transformed Apple’s fortunes, their sophisticated production played a seminal role in financing, training, supervising, and supplying Chinese manufacturers – skills Beijing is now weaponizing against the West.

Investigative journalist Patrick McGee draws on 200 interviews with former Apple executives and engineers to reveal how Cupertino’s choice to anchor its supply chain in China has increasingly made it vulnerable to the regime’s whims. Both an insider’s historical account and a cautionary tale, Apple in China is the first history of Apple to go beyond the biographies of its top executives and set the iPhone’s global domination within an increasingly fraught geopolitical context.

Resource allocation in wireless networks is traditionally approached either through information theory or communications networks. To break down the barriers between these distinct approaches, this book (whose preparation is carried out under the auspices of the EC Network of Excellence in Wireless Communications NEWCOM++) bridges the physical and network layers by providing cross-layer resource allocation techniques, models and methodologies.
Cross-Layer Resource Allocation's unique approach allows optimisation of network resources and will enable engineers to improve signal quality, enhance network and spectrum utilization, increase throughput, and solve the problem of shadowing. Topics covered include different views of spectral efficiency, the role of spatial diversity, of delay in resource allocation, and possible extensions to OFDMA systems.
This will be an ideal reference on cross-layer resource allocation between the PHY and MAC layers for R&D and network design engineers and researchers in universities dealing with sensor networks and cognitive systems.

When choosing the technology options to develop a wireless sensor network (WSN), it is vital that their performance levels can be assessed for the type of application intended. This book describes the different technology options - MAC protocols, routing protocols, localisation and data fusion techniques - and provides the means to numerically measure their performance, whether by simulation, mathematical models or experimental test beds. Case studies, based on the authors' direct experience of implementing wireless sensor networks, describe the design methodology and the type of measurements used, together with samples of the performance measurements attained.
The book will enable you to answer vital questions such as:
* How long will my network remain alive given the amount of sensing required of it?
* For how long should I set the sleeping state of my motes?
* How many sensors should I distribute to meet the expected requirements of the application?
* What type of throughput should I expect as a function of the number of nodes deployed and the radio interface chosen (whether it be Bluetooth or Zigbee)?
* How is the Packet Error Rate of my Zigbee motes affected by the selection of adjacent frequency sub bands in the ISM 2.4GHz band?
* How is the localisation precision dependant on the number of nodes deployed in a corridor?
Communications and signal processing engineers, researchers and graduate students working in wireless sensor networks will find this book an invaluable practical guide to this important technology.

Signal Processing for Active Control sets out the signal processing and automatic control techniques that are used in the analysis and implementation of active systems for the control of sound and vibration. After reviewing the performance limitations introduced by physical aspects of active control, Stephen Elliott presents the calculation of the optimal performance and the implementation of adaptive real time controllers for a wide variety of active control systems.
Active sound and vibration control are technologically important problems with many applications. 'Active control' means controlling disturbance by superimposing a second disturbance on the original source of disturbance. Put simply, initial noise + other specially-generated noise or vibration = silence or controlled noise].
This book presents a unified approach to techniques that are used in the analysis and implementation of different control systems. It includes practical examples at the end of each chapter to illustrate the use of various approaches.
This book is intended for researchers, engineers, and students in the field of acoustics, active control, signal processing, and electrical engineering.

The hidden costs of artificial intelligence—from natural resources and labor to privacy, equality, and freedom.

What happens when artificial intelligence saturates political life and depletes the planet? How is AI shaping our understanding of ourselves and our societies? Drawing on more than a decade of research, award‑winning scholar Kate Crawford reveals how AI is a technology of extraction: from the minerals drawn from the earth to the labor pulled from low-wage information workers to the data taken from every action and expression.

Crawford reveals how this planetary network is fueling a shift toward undemocratic governance and increased inequity. Rather than taking a narrow focus on code and algorithms, Crawford offers us a material and political perspective on what it takes to make AI and how it centralizes power. This is an urgent account of what is at stake as technology companies use artificial intelligence to reshape the world.
