    An Introduction to System Modeling and Control
    A practical and straightforward exploration of the basic tools for the modeling, analysis, and design of control systemsIn An Introduction to System Modeling and Control, Dr. Chiasson delivers an accessible and intuitive guide to understanding modeling and control for students in electrical, mechanical, and aerospace/aeronautical engineering. The book begins with an introduction to the need for control by describing how an aircraft flies complete with figures illustrating roll, pitch, and yaw control using its ailerons, elevators, and rudder, respectively. The book moves on to rigid body dynamics about a single axis (gears, cart rolling down an incline) and then to modeling DC motors, DC tachometers, and optical encoders. Using the transfer function representation of these dynamic models, PID controllers are introduced as an effective way to track step inputs and reject constant disturbances.It is further shown how any transfer function model can be stabilized using output pole placement and on how two-degree of freedom controllers can be used to eliminate overshoot in step responses. Bode and Nyquist theory are then presented with an emphasis on how they give a quantitative insight into a control system's robustness and sensitivity. An Introduction to System Modeling and Control closes with chapters on modeling an inverted pendulum and a magnetic levitation system, trajectory tracking control using state feedback, and state estimation. In addition the book offers:* A complete set of MATLAB/SIMULINK files for examples and problems included in the book.* A set of lecture slides for each chapter.* A solutions manual with recommended problems to assign.* An analysis of the robustness and sensitivity of four different controller designs for an inverted pendulum (cart-pole).Perfect for electrical, mechanical, and aerospace/aeronautical engineering students, An Introduction to System Modeling and Control will also be an invaluable addition to the libraries of practicing engineers.

    Supertall: How the World's Tallest Buildings Are Reshaping Our Cities and Our Lives (eBook, ePUB)
    The global boom in skyscraperswhy it's happening now, how they're made, and what they do to cities and people. We are living in a new urban age, and its most tangible expression is the supertall: megastructures that are dramatically bigger, higher, and more ambitious than any in history. Cities around the world are racing to build the first mile-high building, stretching the limits of engineering and design as never before. In this fascinating work of urban history and design, TED resident Stefan Alhimself an experienced architectexplores the factors that have led to this worldwide boom. He reveals the marvelous and underappreciated feats of engineering that make today's supertalls a reality, from double-decker elevators that silently move up to 50 miles per hour to the sophisticated blend of polymers and steel fibers that enables concrete to withstand 8,000 tons of pressure per square meter. Taking readers behind the scenes of the building and design of remarkable megastructures, both from the past (the Empire State Building, St. Paul's Cathedral, the Eiffel Tower) and the present (Dubai's Burj Khalifa, London's Shard, Shanghai Tower), Al demonstrates the impact of these innovations. Yet while the supertall is undoubtedly a testament to great technological victories, it can come at an environmental and social cost. Focusing on four global citiesLondon, New York, Hong Kong, and SingaporeAl examines the risks of wealth inequality, carbon emissions, and contagion that stem from supertalls. And he uncovers the latest innovations in sustainable building, from skyscrapers made of wood to tree-covered buildings, that promise to yield a better urban future. Featuring more than thirty architectural drawings, Supertall is both a fascinating exploration of our greatest accomplishments and a powerful argument for a more equitable way forward.

    Bunch of Amateurs: A Search for the American Character , Hörbuch, Digital, ungekürzt, 634min
    What is it that drives the success of America and the identity of its people? Acclaimed writer and contributing editor to This America Life Jack Hitt thinks it’s because we’re all a bunch of amateurs.America’s self-invented tinkerers are back at it in their metaphorical garages - fiddling with everything from solar-powered cars to space elevators. In Bunch of Amateurs, Jack Hitt visits a number of different garages and has written a fascinating book that looks at America’s current batch of amateurs and their pursuits. From a tattooed young woman in the Bay Area trying to splice a fish’s glow-in-the-dark gene into common yogurt (all done in her kitchen using salad spinners) to a space fanatic on the brink of developing the next generation of telescopes from his mobile home, Hitt not only tells the stories of people in the grip of a passion but argues that America’s history is bound up in a cycle of amateur surges. Beginning with Ben Franklin’s kite and leading all the way to the current TV hit American Idol, Hitt argues that the nation’s love of self-invented obsessives has always driven the country to rediscover the true heart of the American dream. Amateur pursuits are typically lamented as a world that just passed until a Sergey Brin or Mark Zuckerberg steps out of his garage (or dorm room) with the rare but crucial success story. In Bunch of Amateurs, Hitt argues that America is now poised to pioneer at another frontier that will lead, one more time, to the newest version of the American dream. ungekürzt. Language: English.

    The Residence: Inside the Private World of the White House , Hörbuch, Digital, ungekürzt, 616min
    A remarkable history with elements of both In the President's Secret Service and The Butler, The Residence offers an intimate account of the service staff of the White House, from the Kennedys to the Obamas. America's first families are unknowable in many ways. No one has insight into their true character like the people who serve their meals and make their beds every day. Full of stories and details by turns dramatic, humorous, and heartwarming, The Residence reveals daily life in the White House as it is really lived through the voices of the maids, butlers, cooks, florists, doormen, engineers, and others who tend to the needs of the president and first family. These dedicated professionals maintain the six-floor mansion's 132 rooms, 35 bathrooms, 28 fireplaces, three elevators, and eight staircases and prepare everything from hors d'oeuvres for intimate gatherings to meals served at elaborate state dinners. Over the course of the day, they gather in the lower level's basement kitchen to share stories, trade secrets, forge lifelong friendships, and sometimes even fall in love. Combining incredible first-person anecdotes from extensive interviews with scores of White House staff members - many speaking for the first time - with archival research, Kate Andersen Brower tells their story. She reveals the intimacy between the first family and the people who serve them as well as tension that has shaken the staff over the decades. From the housekeeper and engineer who fell in love while serving President Reagan to Jackie Kennedy's private moment of grief with a beloved staffer after her husband's assassination to the tumultuous days surrounding President Nixon's resignation and President Clinton's impeachment battle, The Residence is full of surprising and moving details that illuminate day-to-day life at the White House. ungekürzt.

    Beyond: Our Future in Space , Hörbuch, Digital, ungekürzt, 555min
    Beyond dares to imagine a fantastic future for humans in space - and then reminds us that we're already there. Human exploration has been an unceasing engine of technological progress, from the first homo sapiens to leave our African cradle to a future in which mankind promises to settle another world. Beyond tells the epic story of humanity leaving home - and how humans will soon thrive in the vast universe beyond the Earth. A dazzling and propulsive voyage through space and time, Beyond reveals how centuries of space explorers - from the earliest stargazers to today's cutting-edge researchers - all draw inspiration from an innate human emotion: wanderlust. This urge to explore led us to multiply around the globe, and it can be traced in our DNA. Today, the urge to discover manifests itself in jaw-dropping ways: plans for space elevators poised to replace rockets at a fraction of the cost; experiments in suspending and reanimating life for ultra-long-distance travel; prototypes for solar sails that coast through space on the momentum of microwaves released from the Earth. With these ventures, private companies and entrepreneurs have the potential to outpace NASA as the leaders in a new space race. Combining expert knowledge of astronomy and avant-garde technology, Chris Impey guides us through the heady possibilities for the next century of exploration. In 20 years, a vibrant commercial space industry will be operating. In 30 years, there will be small but viable colonies on the Moon and Mars. In 50 years, mining technology will have advanced enough to harvest resources from asteroids. In a hundred years, a cohort of humans born off-Earth will come of age without ever visiting humanity's home planet. This is not the stuff of science fiction but rather the logical extension of already available technologies.

    Scatter, Adapt, and Remember: How Humans Will Survive a Mass Extinction , Hörbuch, Digital, ungekürzt, 619min
    In its 4.5 billion–year history, life on Earth has been almost erased at least half a dozen times: shattered by asteroid impacts, entombed in ice, smothered by methane, and torn apart by unfathomably powerful megavolcanoes. And we know that another global disaster is eventually headed our way. Can we survive it? How? As a species, Homo sapiens is at a crossroads. Study of our planet’s turbulent past suggests that we are overdue for a catastrophic disaster, whether caused by nature or by human interference. It’s a frightening prospect, as each of the Earth’s past major disasters–from meteor strikes to bombardment by cosmic radiation–resulted in a mass extinction, where more than 75 percent of the planet’s species died out. But in Scatter, Adapt, and Remember, Annalee Newitz, science journalist and editor of the science Web site io9.com explains that although global disaster is all but inevitable, our chances of long-term species survival are better than ever. Life on Earth has come close to annihilation–humans have, more than once, narrowly avoided extinction just during the last million years–but every single time a few creatures survived, evolving to adapt to the harshest of conditions. This brilliantly speculative work of popular science focuses on humanity’s long history of dodging the bullet, as well as on new threats that we may face in years to come. Most important, it explores how scientific breakthroughs today will help us avoid disasters tomorrow. From simulating tsunamis to studying central Turkey’s ancient underground cities; from cultivating cyanobacteria for “living cities” to designing space elevators to make space colonies cost-effective; from using math to stop pandemics to studying the remarkable survival strategies of gray whales, scientists and researchers the world over are discovering the keys to long-term resilience and learning how humans can choose life over death.

    Does the Noise in My Head Bother You?: A Rock 'n' Roll Memoir , Hörbuch, Digital, ungekürzt, 782min
    I've been mythicized, Mick-icized, eulogized and fooligized, I've been Cole-Portered and farmer's-daughtered, I've been Led Zepped and 12-stepped. I'm a rhyming fool and so cool that me, Fritz the Cat, and Mohair Sam are the baddest cats that am. I have so many outrageous stories, too many, and I'm gonna tell 'em all. All the unexpurgated, brain-jangling tales of debauchery, sex, drugs, transcendence, chemical dependence you will ever want to hear. The son of a classical pianist straight out of the Bronx of old Archie comics, Steven Tyler was born to be a rock star. Weaned on Cole Porter, Nat King Cole, Mick, and his beloved Janis Joplin, Tyler began tearing up the streets and the stage as a teenager before finally meeting his "mutant twin" and legendary partner, Joe Perry. In this addictively listenable memoir, told in the playful, poetic voice that is uniquely his own, Tyler unabashedly recounts the meteoric rise, fall, and rise of Aerosmith over the last three decades and riffs on the music that gives it all meaning. Tyler tells what it's like to be a living legend and the frontman of one of the world's most revered and infamous bands - the debauchery, the money, the notoriety, the fights, the motels and hotels, the elevators, limos, buses and jets, the rehab. He reveals the spiritual side that "gets lost behind the stereotype of the Sex Guy, the Drug Guy, the Demon of Screamin', the Terror of the Tropicana." And he talks about his epic romantic life and his relationship with his four children. As dazzling, bold, and out-on-the-edge as the man himself, Does the Noise in My Head Bother You? is an all-access backstage pass into this extraordinary showman's life. ungekürzt. Language: English.

    Commercial Real Estate Investing: The Ultimate Beginner's Guide to Learn How to Invest in Commercial Real Estate and Build Your Real Estate Empire , Hörbuch, Digital, ungekürzt, 55min
    Discover the ultimate beginner's guide to learn how to invest in commercial real estate and build your real estate empire. Then be able to achieve financial freedom and live the life of your dreams! Real estate has been in existence since people have decided that living in caves was no longer an option. However, most progress in real estate has probably happened in the last two centuries or so with the invention of the elevator. Elevators made it possible for real estate to include high-rise office buildings, multiple-floor residential apartment houses, and shopping malls. Investing in commercial real estate is very different from dealing with residential properties. Oftentimes commercial real estate deals require very little or even no capital. While commercial estate can be very risky, it can also be very safe because of a number of things you can do with commercial buildings that you can't do with residential dwellings. We will discuss all these differences and strategies later on in this book. Most people think that investing in commercial real estate is very similar to dealing with residential properties with the only differences being that that the money amounts are larger and contracts are longer. The reality is completely different. There are a lot of distinctions between commercial and residential real estate when it comes to legal, practical and operational aspects. Investing in commercial real estate is a great way to build wealth. The reason why commercial estate is a great vehicle for generating wealth can be explained in one word. This word is leverage. Leverage when applied to commercial real estate means that your returns from your commercial real estate investments can be much bigger than the time and effort you put into this business. Commercial properties are usually much more valuable than residential real estate such as apartments, condos or houses. ungekürzt. Language: English. Narrator: Robert Barbere.
