This book is about nonlinear observability. It provides a modern theory of observability based on a new paradigm borrowed from theoretical physics and the mathematical foundation of that paradigm. In the case of observability, this framework takes into account the group of invariance that is inherent to the concept of observability, allowing the reader to reach an intuitive derivation of significant results in the literature of control theory. The book provides a complete theory of observability and, consequently, the analytical solution of some open problems in control theory. Notably, it presents the first general analytic solution of the nonlinear unknown input observability (nonlinear UIO), a very complex open problem studied in the 1960s. Based on this solution, the book provides examples with important applications for neuroscience, including a deep study of the integration of multiple sensory cues from the visual and vestibular systems for self-motion perception. Observability: A New Theory Based on the Group of Invariance is the only book focused solely on observability. It provides readers with many applications, mostly in robotics and autonomous navigation, as well as complex examples in the framework of vision-aided inertial navigation for aerial vehicles. For these applications, it also includes all the derivations needed to separate the observable part of the system from the unobservable, an analysis with practical importance for obtaining the basic equations for implementing any estimation scheme or for achieving a closed-form solution to the problem. This book is intended for researchers in robotics and automation, both in academia and in industry. Researchers in other engineering disciplines, such as information theory and mechanics, will also find the book useful.

This book constitutes the thoroughly refereed post-proceedings of the 2004 International Workshop on Intuitive Human Interfaces for Organizing and Accessing Intellectual Assets, held in Dagstuhl Castle, Germany in March 2004. The 17 revised full papers presented together with an introductory overview have gone through two rounds of reviewing and revision. The papers are organized in topical sections on man-machine interface for intuitive knowledge access, intelligent pad and meme media, visualization and design of information access spaces, and semantics and narrative organization and access of knowledge.

Tony Buck Nowlan, the inventor of the highly-secret time-machine called the ChronoSpace, is back on a new journey filled with danger, mystery, and unexpected twists. Returning from his honeymoon, Tony discovers a shocking secret about his personal history, but investigating it means breaking a promise to his wife Erin: not to travel back in time before the birth of their first-born. However, curiosity gets the better of him and he travels back to minutes after his own birth, only to be thrown further into time by his malfunctioning ChronoSpace. As he jumps through time, he witnesses some of the most devastating disasters in human history and crosses paths with other time-travellers, some of whom become allies in his quest to return home, while others have sinister plots in mind. Tony must navigate the dangers of the past and present, all while learning the true meaning of trust, loyalty, and sacrifice. Get ready for a pulse-pounding journey that will keep you on the edge of your seat. Will Tony make it back to his own time, or will he be trapped in the past forever?

Earth’s past and future are altered by twenty-fourth-century time travelers in this “significant work of science fiction” from the author of Arkwright (Rocky Mountain News). Chrononaut Franc Lu has come a long, long way—from the twenty-fourth century, in fact—to be in New Jersey on the evening of May 6, 1937. Traveling four hundred years into the past, he and his partner have been sent by the Chronospace Research Centre to observe the infamous explosion of the zeppelin Hindenburg. But when the German airship touches down safely on the airfield in Lakehurst, Lu realizes that something has gone terribly wrong—or rather, horribly right. His presence at the landing has set in motion an alternate historical timeline, and now everything will be different, though not necessarily in a good way. The consequences of Lu’s mistake could prove catastrophic for every living soul on Earth, now and forever, unless the past and the future are somehow repaired—and that is a burden destined to fall on the shoulders of visionary NASA scientist and wannabe science fiction author Dr. David Zachary Murphy. An expansion of his Hugo Award–winning novella “ ‘. . . Where Angels Fear to Tread,’ ” Allen Steele’s Time Loves a Hero is at once thrilling, surprising, startling, and thoughtful—a mind-blowing masterwork of speculative fiction that radically reimagines time travel, alien contact, alternate history, and a host of other well-worn science fiction tropes.

Under the banner of family values, a war of more than words is being waged. At stake is the control of contemporary national culture-and the consciousness of succeeding generations. Michael J. Shapiro enters the fray with this galvanizing book, which exposes the assumptions, misconceptions, and historical inaccuracies that mark the neoconservative campaign to redeem an imagined past and colonize the present and future with a moral and political commitment to the "traditional family." Challenging the neoconservative assumption of a natural relation between a historically constant, traditional family structure and civic life, Shapiro shows how the situation of the family in relation to public life has emerged differently in different historical periods. For Moral Ambiguity juxtaposes moralizing versus historically sensitive, critical treatments of familial and public attachments, revealing how "the family"-as represented in historical and contemporary fiction, cinema, television, and other genres and media-emerges as a contingent cultural and historical structure. Shapiro treats the ways in which family space, however changeable, serves as a critical locus of "enunciation"-as a space from which diverse family personae challenge the relationships and historical narratives that support dominant structures of power and authority and offer ways to renegotiate the problem of "the political." By extending recognition to less heeded voices and genres of expression, he seeks to frame the political within a democratic ethos. Ultimately, the book compels us to understand "the political" as the continuous negotiation of different modes of civic presence.

Gold Digger Black and White #32 OCT 1996 Time Warp: Part 1 of 8 A mysterious super-intelligent canine from the future has a grand design for mankind -- one that will eventually spawn the invisible Universal Empire ruled by ultra-genius dogs! His mission: go back into mankind's history to plant the seeds of his future -- to "correct" human history. But first he must get rid of anyone who can interfere with his plans. His first targets: Mita Celande, time-traveling teacher of Quagmire High School, and Brianna Diggers. Can he trick them into going back in time to erase each other's pasts?

This Here Now explains how traditional Japanese buildings respond to distinctive materials, objects and moments, and argues that the built acknowledgment of such events can help to affirm the individuality of our own being. The book also shows how buildings can help us to overcome our separateness by enabling us to share the normally subjective experiences of this, here and now.

When Claire Hilyer receives a mysterious letter and package from her best friend Tony, she thinks it an unexpected romantic gesture. Then she learns Tony sent it over twenty-five years ago, before his birth. Intrigued, Claire visits Tony's house. She arrives in time to see him fighting a stranger, and a moment later, they vanish before her eyes into the past. Tony's package is a cry for help from 2017 to Claire. He must learn to survive without money, family or friends in an era before his birth. Meanwhile, a deadly enemy craves Tony's invention - a time travelling device - for his own deadly purposes and stalks him from the past and the future. Can Claire save Tony and bring him home before time runs out?
