Scientists also predict that if nothing is done to curb the effects of climate change, in Europe the death toll due to weather disasters could rise 50-fold by the end of the 21st century, with extreme heat alone causing more than 150,000 deaths a year, as the report on global warming of 1.5°C warns that China, Russia and Canada’s current climate policies would steer the world above a catastrophic 5°C of warming by the end of 2100. As such, the book highlights how the wellbeing of different populations is threatened by extreme events now and in the foreseeable future.
Extremely Hardcore: Inside Elon Musk's Twitter
by Zoë Schiffer"Zoë Schiffer has written the definitive book on perhaps the weirdest business story of our time. A fast-paced and riveting account of a hilarious and tragic mess."— Matt Levine, Bloomberg Opinion &“Money Stuff&” columnist&“the bird is freed&”- Elon Musk (@elonmusk) October 27, 2022When Elon Musk took over Twitter, commentators were rooting for the visionary behind Tesla and SpaceX to succeed. Here was a tough leader who could grab back power from Twitter&’s entitled workforce, motivate them to get &“extremely hardcore,&” and supercharge Twitter&’s profit and potential. And it was all out of the goodness of his own heart, rooted in his fervent belief in the necessity of making Twitter friendlier to free speech. "I didn&’t do it to make more money,&” Musk said. &“I did it to try and help humanity, whom I love.&” Once Musk charged into the Twitter headquarters, the command-and-control playbook Musk honed at Tesla and SpaceX went off the rails immediately. Distilling hundreds of hours of interviews with more than sixty employees, thousands of pages of internal documents, Slack messages, presentations, as well as court filings and congressional testimony, Extremely Hardcore is the true story of how Musk reshaped the world&’s online public square into his own personal megaphone. You&’ll hear from employees who witnessed the destruction of their workplace in real-time, seeing years of progress to fight disinformation and hate speech wiped out within a matter of months. There&’s the machine-learning savant who went all-in on Twitter 2.0 before getting betrayed by his new CEO, the father whose need for healthcare swept him into Musk&’s inner circle, the trust and safety expert who became the subject of a harassment campaign his former boss incited, and the many other employees who tried to save the company from their new boss&’s worst instincts. This is the story of Twitter, but it&’s also a chronicle of the post-pandemic labor movement, a war between executives and a workforce newly awakened to their rights and needs. Riveting, character-driven, and filled with jaw-dropping revelations, Extremely Hardcore is the definitive, fly-on-the-wall story of how Elon Musk lit $44 billion on fire and burned down Twitter. It&’s the next best thing to being there, and you won&’t have to sleep in the Twitter office to get the scoop.
Extremely Loud: Sound as a Weapon
by Juliette Volcler&“Everything you ever suspected or feared about music as a weapon, sound as torture . . . Disturbingly illuminating in the possible ramifications&” (Kirkus Reviews). In this troubling and wide-ranging account, acclaimed journalist Juliette Volcler looks at the long history of efforts by military and police forces to deploy sound against enemies, criminals, and law-abiding citizens. During the 2004 battle over the Iraqi city of Fallujah, US Marines bolted large speakers to the roofs of their Humvees, blasting AC/DC, Eminem, and Metallica songs through the city&’s narrow streets as part of a targeted psychological operation against militants that has now become standard practice in American military operations in Afghanistan. In the historic center of Brussels, nausea-inducing sound waves are unleashed to prevent teenagers from lingering after hours. High-decibel, &“nonlethal&” sonic weapons have become the tools of choice for crowd control at major political demonstrations from Gaza to Wall Street and as a form of torture at Guantanamo and elsewhere. In an insidious merger of music, technology, and political repression, loud sound has emerged in the last decade as an unlikely mechanism for intimidating individuals as well as controlling large groups. &“Thorough and well researched,&” Extremely Loud documents and interrogates this little-known modern phenomenon, exposing it as a sinister threat to the peace and quiet that societies have traditionally craved (Publishers Weekly). &“Extremely Loud makes you shiver, or cover your ears, at the technological buildup now at the service of the most sophisticated forms of repression.&” —Libération
Extremely Online: The Untold Story of Fame, Influence, and Power on the Internet
by Taylor LorenzNATIONAL BESTSELLER Acclaimed Washington Post reporter Taylor Lorenz presents a groundbreaking social history of the internet, revealing how online influence and the creators who amass it have reshaped our world, online and off—&“terrific,&” as the New York Times calls it, &“Lorenz…is a knowledgeable, opinionated guide to the ways internet fame has become fame, full stop.&”For over a decade, Taylor Lorenz has been the authority on internet culture, documenting its far-reaching effects on all corners of our lives. Her reporting is serious yet entertaining and illuminates deep truths about ourselves and the lives we create online. In her debut book, Extremely Online, she reveals how online influence came to upend the world, demolishing traditional barriers and creating whole new sectors of the economy. Lorenz shows this phenomenon to be one of the most disruptive changes in modern capitalism. By tracing how the internet has changed what we want and how we go about getting it, Lorenz unearths how social platforms&’ power users radically altered our expectations of content, connection, purchasing, and power. In this &“deeply reported, behind-the-scenes chronicle of how everyday people built careers and empires from their sheer talent and algorithmic luck&” (Sarah Frier, author of No Filter), Lorenz documents how moms who started blogging were among the first to monetize their personal brands online, how bored teens who began posting selfie videos reinvented fame as we know it, and how young creators on TikTok are leveraging opportunities to opt out of the traditional career pipeline. It&’s the real social history of the internet. Emerging seemingly out of nowhere, these shifts in how we use the internet seem easy to dismiss as fads. However, these social and economic transformations have resulted in a digital dynamic so unappreciated and insurgent that it ultimately created new approaches to work, entertainment, fame, and ambition in the 21st century. &“Extremely Online aims to tell a sociological story, not a psychological one, and in its breadth it demonstrates a new cultural logic emerging out of 21st-century media chaos&” (The New York Times). Lorenz reveals the inside, untold story of what we have done to the internet, and what it has done to us.

Extremum-Seeking Control and Applications
by Chunlei Zhang Raúl OrdóñezExtremum-seeking control tracks a varying maximum or minimum in a performance function such as output or cost. It attempts to determine the optimal performance of a control system as it operates, thereby reducing downtime and the need for system analysis. Extremum-seeking Control and Applications is divided into two parts. In the first, the authors review existing analog-optimization-based extremum-seeking control including gradient-, perturbation- and sliding-mode-based control designs. They then propose a novel numerical-optimization-based extremum-seeking control based on optimization algorithms and state regulation. This control design is developed for simple linear time-invariant systems and then extended for a class of feedback linearizable nonlinear systems. The two main optimization algorithms - line search and trust region methods - are analyzed for robustness. Finite-time and asymptotic state regulators are put forward for linear and nonlinear systems respectively. Further design flexibility is achieved using the robustness results of the optimization algorithms and the asymptotic state regulator by which existing nonlinear adaptive control techniques can be introduced for robust design. The approach used is easier to implement and tends to be more robust than those that use perturbation-based extremum-seeking control. The second part of the book deals with a variety of applications of extremum-seeking control: a comparative study of extremum-seeking control schemes in antilock braking system design; source seeking, formation control, collision and obstacle avoidance for groups of autonomous agents; mobile radar networks; and impedance matching. MATLAB®/Simulink® code which can be downloaded from www.springer.com/ISBN helps readers to reproduce the results presented in the text and gives them a head start for implementing the algorithms in their own applications. Extremum-seeking Control and Applications will interest academics and graduate students working in control, and industrial practitioners from a variety of backgrounds: systems, automotive, aerospace, communications, semiconductor and chemical engineering.
