Book Description
This monograph describes the Reaction Wheel Pendulum, the newest inverted-pendulum-like device for control education and research. We discuss the history and background of the reaction wheel pendulum and other similar experimental devices. We develop mathematical models of the reaction wheel pendulum in depth, including linear and nonlinear models, and models of the sensors and actuators that are used for feedback control. We treat various aspects of the control problem, from linear control of themotor, to stabilization of the pendulum about an equilibrium configuration using linear control, to the nonlinear control problem of swingup control. We also discuss hybrid and switching control, which is useful for switching between the swingup and balance controllers. We also discuss important practical issues such as friction modeling and friction compensation, quantization of sensor signals, and saturation. This monograph can be used as a supplement for courses in feedback control at the undergraduate level, courses in mechatronics, or courses in linear and nonlinear state space control at the graduate level. It can also be used as a laboratory manual and as a reference for research in nonlinear control.

Book Description
Politics, manners, humor, sexuality, wealth, even our definitions of success are periodically renegotiated based on the new values society chooses to use as a lens to judge what is acceptable. Are these new values randomly chosen or is there a pattern? Pendulum chronicles the stuttering history of western society; that endless back-and-forth swing between one excess and another, always reminded of what we left behind. There is a pattern and it is 40 years: 2003 was a fulcrum year, as was 1963, its opposite. Pendulum explains where we have been as a society, how we got here, and where we are headed. If you would benefit from a peek into the future, you would do well to read this book.

Book Description
Three book editors, jaded by reading far too many crackpot manuscripts on the mystic and the occult, are inspired by an extraordinary conspiracy story told to them by a strange colonel to have some fun. They start feeding random bits of information into a powerful computer capable of inventing connections between the entries, thinking they are creating nothing more than an amusing game, but then their game starts to take over, the deaths start mounting, and they are forced into a frantic search for the truth

Book Description
You have one chance. Run. "ONE OF THE BEST THRILLERS OF THE YEAR" -- JAMES PATTERSON, bestselling author. Photojournalist John Wallace struggles to consciousness to find he has been bound and blindfolded by a masked man who is preparing to hang him in his own living room. Forced onto a chair with a noose around his neck, Wallace briefly reconsiders his mostly lonely life before the chair is kicked out beneath him and his world fades to black. Then he gets lucky and manages to escape his apartment, just ahead of his assailant. Bloody, barefoot, and with at least one broken rib, he has no choice but to run for his life. When his would-be killer strikes again, Wallace realizes he will have to figure out who is hunting him and stop him on his own. The pendulum of fate swung briefly in his favor, but it's only a matter of time before its momentum carries it to the other side . . .

Book Description
As new presidential administrations come into power, they each bring their own approach to foreign policy. No grand strategy, however, is going to be completely novel. New administrations never start with a blank slate, so it is always possible to see similarities between an administration and its predecessors. Conversely, since each administration faces novel problems and operates in a unique context, no foreign policy strategy is going to be an exact replica of its predecessors. In American Pendulum, Christopher Hemmer examines America's grand strategic choices between 1914 and 2014 using four recurring debates in American foreign policy as lenses. First, how should the United States balance the trade-offs between working alone versus working with other states and international organizations? Second, what is the proper place of American values in foreign policy? Third, where does the strategic perimeter of the United States lie? And fourth, is time on the side of the United States or of its enemies?Offering new readings of debates within the Wilson, Truman, Nixon, Bush, and Obama administrations, Hemmer asserts that heated debates, disagreements, and even confusions over U.S. grand strategy are not only normal but also beneficial. He challenges the claim that uncertainties or inconsistences about the nation's role in the world or approach to security issues betray strategic confusion or the absence of a grand strategy. American foreign policy, he states, is most in danger not when debates are at their most pointed but when the weight of opinion crushes dissent. As the United States looks ahead to an increasingly multipolar world with increasing complicated security issues, Hemmer concludes, developing an effective grand strategy requires ongoing contestation and compromises between competing visions and policies.
