Book Description
This book presents a three-dimensional model of the complete unicycle–unicyclist system. A unicycle with a unicyclist on it represents a very complex system. It combines Mechanics, Biomechanics and Control Theory into the system, and is impressive in both its simplicity and improbability. Even more amazing is the fact that most unicyclists don’t know that what they’re doing is, according to science, impossible – just like bumblebees theoretically shouldn’t be able to fly. This book is devoted to the problem of modeling and controlling a 3D dynamical system consisting of a single-wheeled vehicle, namely a unicycle and the cyclist (unicyclist) riding it. The equations of motion are derived with the aid of the rarely used Boltzmann–Hamel Equations in Matrix Form, which are based on quasi-velocities. The Matrix Form allows Hamel coefficients to be automatically generated, and eliminates all the difficulties associated with determining these quantities. The equations of motion are solved by means of Wolfram Mathematica. To more faithfully represent the unicyclist as part of the model, the model is extended according to the main principles of biomechanics. The impact of the pneumatic tire is investigated using the Pacejka Magic Formula model including experimental determination of the stiffness coefficient. The aim of control is to maintain the unicycle–unicyclist system in an unstable equilibrium around a given angular position. The control system, based on LQ Regulator, is applied in Wolfram Mathematica. Lastly, experimental validation, 3D motion capture using software OptiTrack – Motive:Body and high-speed cameras are employed to test the model’s legitimacy. The description of the unicycle–unicyclist system dynamical model, simulation results, and experimental validation are all presented in detail.

Book Description
The definitive history of America’s greatest incubator of innovation and the birthplace of some of the 20th century’s most influential technologies “Filled with colorful characters and inspiring lessons . . . The Idea Factory explores one of the most critical issues of our time: What causes innovation?” —Walter Isaacson, The New York Times Book Review “Compelling . . . Gertner's book offers fascinating evidence for those seeking to understand how a society should best invest its research resources.” —The Wall Street Journal From its beginnings in the 1920s until its demise in the 1980s, Bell Labs-officially, the research and development wing of AT&T-was the biggest, and arguably the best, laboratory for new ideas in the world. From the transistor to the laser, from digital communications to cellular telephony, it's hard to find an aspect of modern life that hasn't been touched by Bell Labs. In The Idea Factory, Jon Gertner traces the origins of some of the twentieth century's most important inventions and delivers a riveting and heretofore untold chapter of American history. At its heart this is a story about the life and work of a small group of brilliant and eccentric men-Mervin Kelly, Bill Shockley, Claude Shannon, John Pierce, and Bill Baker-who spent their careers at Bell Labs. Today, when the drive to invent has become a mantra, Bell Labs offers us a way to enrich our understanding of the challenges and solutions to technological innovation. Here, after all, was where the foundational ideas on the management of innovation were born.

A Newbery Honor Book * Booklist Editors’ Choice * BookPage Best Books * Chicago Public Library Best Fiction * Horn Book Fanfare * Kirkus Reviews Best Books * Publishers Weekly Best Books * Wall Street Journal Best of the Year * An ALA Notable Book A young outcast is swept up into a thrilling and perilous medieval treasure hunt in this award-winning literary page-turner by acclaimed bestselling author Catherine Gilbert Murdock. The Book of Boy was awarded a Newbery Honor. “A treat from start to finish.”—Wall Street Journal Boy has always been relegated to the outskirts of his small village. With a hump on his back, a mysterious past, and a tendency to talk to animals, he is often mocked by others in his town—until the arrival of a shadowy pilgrim named Secondus. Impressed with Boy’s climbing and jumping abilities, Secondus engages Boy as his servant, pulling him into an action-packed and suspenseful expedition across Europe to gather seven precious relics of Saint Peter. Boy quickly realizes this journey is not an innocent one. They are stealing the relics and accumulating dangerous enemies in the process. But Boy is determined to see this pilgrimage through until the end—for what if St. Peter has the power to make him the same as the other boys? This epic and engrossing quest story by Newbery Honor author Catherine Gilbert Murdock is for fans of Adam Gidwitz’s The Inquisitor’s Tale and Grace Lin’s Where the Mountain Meets the Moon, and for readers of all ages.

Book Description
This is the incredible 20 year saga of a globe-trotting adventure traveler who rode for his life. Jim Doilney was a PhD in economics and university professor when he kicked academia away and moved to a small mountain town in Utah. Within a few years he had a successful resort business and made a promise to himself to make time every year for long treks ...to places nobody goes, to meet people nobody knows. Traveling by foot or by bike, he crossed faraway deserts, climbed mountain peaks, hiked through tropical jungles and over glacier passes. His plan was no plan and he deliberately set out with minimal equipment and comforts, testing himself against deprivation and physical limits. He skied down active volcanos, waded through crocodile-infested rivers, dodged angry grizzlies and great white sharks, spending hours in a company of unique characters--- never-give-up hippies, burned-out surfers, laid-back expats, remote farmers, cocaine cowboys, backwater entrepreneurs, and a host of fellow travelers who shared the road. From the beaches of Mexico to the coasts of Australia, from frigid Patagonia to steamy Cuba, from magical New Zealand to Kathmandu, from Alaska to Scotland, from Cape Town to Spain, from Hawaii to the Himalayas, from the Panama Canal to the mountains of Spain, he hiked and biked---until tragedy struck. Facing a fatal diagnosis of prostate cancer, he weighed the only treatments offered---radical surgery, chemo or radiation, along with the brutal life-changing after-effects---and rejected them all. 'Butcher me, bake me or burn me, he called them, and vowed to find the alternate path. Twenty years later, he has lived to write this journal. Not just to relate his adventures, but to tell the thousands of aging men who every year face death from prostate cancer that there is another way. He is still trekking.

Book Description
Completely revised and updated, this best-selling introduction to programming in JavaScript focuses on writing real applications. JavaScript lies at the heart of almost every modern web application, from social apps like Twitter to browser-based game frameworks like Phaser and Babylon. Though simple for beginners to pick up and play with, JavaScript is a flexible, complex language that you can use to build full-scale applications. This much anticipated and thoroughly revised third edition of Eloquent JavaScript dives deep into the JavaScript language to show you how to write beautiful, effective code. It has been updated to reflect the current state of Java¬Script and web browsers and includes brand-new material on features like class notation, arrow functions, iterators, async functions, template strings, and block scope. A host of new exercises have also been added to test your skills and keep you on track. As with previous editions, Haverbeke continues to teach through extensive examples and immerses you in code from the start, while exercises and full-chapter projects give you hands-on experience with writing your own programs. You start by learning the basic structure of the JavaScript language as well as control structures, functions, and data structures to help you write basic programs. Then you'll learn about error handling and bug fixing, modularity, and asynchronous programming before moving on to web browsers and how JavaScript is used to program them. As you build projects such as an artificial life simulation, a simple programming language, and a paint program, you'll learn how to: - Understand the essential elements of programming, including syntax, control, and data - Organize and clarify your code with object-oriented and functional programming techniques - Script the browser and make basic web applications - Use the DOM effectively to interact with browsers - Harness Node.js to build servers and utilities Isn't it time you became fluent in the language of the Web? * All source code is available online in an inter¬active sandbox, where you can edit the code, run it, and see its output instantly.
