Power and Progress: Our Thousand-Year Struggle Over Technology and Prosperity
by Simon Johnson Daron AcemogluThe bestselling co-author of Why Nations Fail and the bestselling co-author of 13 Bankers deliver a bold reinterpretation of economics and history that will fundamentally change how you see the world A thousand years of history and contemporary evidence make one thing clear: progress depends on the choices we make about technology. New ways of organizing production and communication can either serve the narrow interests of an elite or become the foundation for widespread prosperity. The wealth generated by technological improvements in agriculture during the European Middle Ages was captured by the nobility and used to build grand cathedrals, while peasants remained on the edge of starvation. The first hundred years of industrialization in England delivered stagnant incomes for working people. And throughout the world today, digital technologies and artificial intelligence undermine jobs and democracy through excessive automation, massive data collection, and intrusive surveillance. It doesn&’t have to be this way. Power and Progress demonstrates the path of technology was once—and may again—be brought under control. Cutting-edge technological advances can become empowering and democratizing tools, but not if all major decisions remain in the hands of a few hubristic tech leaders. With their bold reinterpretation of economics and history, Daron Acemoglu and Simon Johnson fundamentally change how we see the world, providing the vision needed to redirect innovation so it again benefits most people.
Power and the Vote
by Brian MinHow do developing states decide who gets access to public goods like electricity, water, and education? Power and the Vote breaks new ground by showing that the provision of seemingly universal public goods is intricately shaped by electoral priorities. In doing so, this book introduces new methods using high-resolution satellite imagery to study the distribution of electricity across and within the developing world. Combining cross-national evidence with detailed sub-national analysis and village-level data from India, Power and the Vote affirms the power of electoral incentives in shaping the distribution of public goods and challenges the view that democracy is a luxury of the rich with little relevance to the world's poor.
Power-Aware Testing and Test Strategies for Low Power Devices
by Xiaoqing Wen Nicola Nicolici Patrick GirardManaging the power consumption of circuits and systems is now considered one of the most important challenges for the semiconductor industry. Elaborate power management strategies, such as dynamic voltage scaling, clock gating or power gating techniques, are used today to control the power dissipation during functional operation. The usage of these strategies has various implications on manufacturing test, and power-aware test is therefore increasingly becoming a major consideration during design-for-test and test preparation for low power devices. This book explores existing solutions for power-aware test and design-for-test of conventional circuits and systems, and surveys test strategies and EDA solutions for testing low power devices.
Power-Based Study of Boundary Layer Ingestion for Aircraft Application (SpringerBriefs in Applied Sciences and Technology)
by Peijian LvThis book presents research on Boundary Layer Ingestion (BLI). BLI is an aircraft-engine integration technique that aims at integrating the aircraft and the propulsion system such that the overall aircraft fuel consumption can be reduced. In this research, theoretical analysis suggests that the minimization of total power consumption should be used as a design criterion for aircraft utilizing BLI rather than focusing on the minimization of drag. Numerical simulations are performed, and the simulation results are processed using the PBM to support the theoretical analysis. Furthermore, an experimental study is carried out with a focus on the power conversion processes involved for a propulsor operating in the wake. Stereoscopic PIV is employed in order to visualize the flow and understand the physics. The so-called Power-based Method is used to quantify the power conversion mechanisms. The results prove that the dominant mechanism responsible for the efficiency enhancement is due to the utilization of body wake energy by the wake ingesting propeller. In short, the importance of wake energy flow rate in understanding the BLI phenomenon is highlighted. This book will be useful for researchers in the field of aircraft propulsion, aircraft aerodynamics, and airframe propulsion integration.
Power Button: A History of Pleasure, Panic, and the Politics of Pushing
by Rachel PlotnickPush a button and turn on the television; tap a button and get a ride; click a button and “like” something. The touch of a finger can set an appliance, a car, or a system in motion, even if the user doesn't understand the underlying mechanisms or algorithms. How did buttons become so ubiquitous? Why do people love them, loathe them, and fear them? In Power Button, Rachel Plotnick traces the origins of today's push-button society by examining how buttons have been made, distributed, used, rejected, and refashioned throughout history. Focusing on the period between 1880 and 1925, when “technologies of the hand” proliferated (including typewriters, telegraphs, and fingerprinting), Plotnick describes the ways that button pushing became a means for digital command, which promised effortless, discreet, and fool-proof control. Emphasizing the doubly digital nature of button pushing—as an act of the finger and a binary activity (on/off, up/down)—Plotnick suggests that the tenets of precomputational digital command anticipate contemporary ideas of computer users. Plotnick discusses the uses of early push buttons to call servants, and the growing tensions between those who work with their hands and those who command with their fingers; automation as “automagic,” enabling command at a distance; instant gratification, and the victory of light over darkness; and early twentieth-century imaginings of a future push-button culture. Push buttons, Plotnick tells us, have demonstrated remarkable staying power, despite efforts to cast button pushers as lazy, privileged, and even dangerous.
