While some automatic navigation systems can use external measurements to determine their position (as the driver of a car uses road signs, or more recent automated systems use satellite data), others (such as those used in submarines) cannot. They must rely instead on internal measurements of the acceleration to determine their speed and position. Such inertial guidance systems have been in use since Word War II, and modern navigation would be impossible without them. This book describes the inertial technology used for guidance, control, and navigation, discussing in detail the principles, operation, and design of sensors, gyroscopes, and accelerometers, as well as the advantages and disadvantages of particular systems. An engineer with long practical experience in the field, the author elucidates the most recent developments in inertial guidance. Among these are fiber-optic gyroscopes, solid-state accelerometers, and the Global Positioning System. The book should be of interest to researchers and practicing engineers involved in systems engineering, aeronautics, space research, and navigation on land and on sea. This second edition has been brought up to date throughout, and includes new material on micromachined gyroscopes.

Radicals in Their Own Time explores the lives of five Americans, with lifetimes spanning four hundred years, who agitated for greater freedom in America. Every generation has them: individuals who speak truth to power and crave freedom from arbitrary authority. This book makes two important observations in discussing Roger Williams, Thomas Paine, Elizabeth Cady Stanton, W. E. B. Du Bois and Vine Deloria, Jr. First, each believed that government must broadly tolerate individual autonomy. Second, each argued that religious orthodoxy has been a major source of society's ills - and all endured serious negative repercussions for doing so. The book challenges Christian orthodoxy and argues that part of what makes these five figures compelling is their willingness to pay the price for their convictions - much to the lasting benefit of liberty and equal justice in America.

'Lawrence's poems are skilfully made artefacts and intensely experiential...[His] characteristic attraction to intensity pays off in a newly austere lyricism.' ("The Age", Melbourne). Anthony Lawrence is one of Australia's most highly-regarded poets and winner of two of the country's most prestigious poetry prizes. He characteristically sets his poems within powerful landscapes and seascapes. There is a dramatic confrontation in them, between the elemental forces of nature, and those within the consciousness of his characters. His focus is on relationships, the rhythms of work, and the presence of danger in these primal settings. In an interview, Lawrence says of his work: "I'd like to think that [...] my poems achieve this tricky balance: landscape veined with humanity, flora, fauna, what's imagined and what's experienced [...] I write about nature to define my life." "Strategies for Confronting Fear", a selection from his seven most recent poetry collections plus a substantial body of new work, is Lawrence's first volume of poetry to be published in the UK. 'Lawrence has crept up on the audience for Australian poetry. He is now one of the most assured and challenging of our poets. This volume ["The Sleep of a Learning Man"] is a testament to craft skills at the service of a relentless self-questioning.' ("Australian Book Review").

When Tomorrow Comes, the second work in a series on survival in the urban ghetto,introduces naive teenager, Douglas, forced to adjust to his ever-changing environment. The mean streets are hostile and Douglas must make choices. "When Tomorrow Comes" describes how only spiritual values and family commitment save Douglas from the onslaught of hostile urban challenges.

The elders met in their great hall to determine the order of the upcoming battle with the Sev Tribe. Hava Scmitt knew it would be difficult to engage in battle at this time. How could he fight against the city of Lodi? The place of his birth. Against his old friend Seva Timsh. If ever a final battle was to be fought, it was never in the mind of Seva Timsh to invade Gor. No, if the Havs wanted a battle, they would have to come to him. For both tribes, it would be a fight for their survival, and their way of life.
