Book Description
Search Theory is one of the original disciplines within the field of Operations Research. It deals with the problem faced by a Searcher who wishes to minimize the time required to find a hidden object, or “target. ” The Searcher chooses a path in the “search space” and finds the target when he is sufficiently close to it. Traditionally, the target is assumed to have no motives of its own regarding when it is found; it is simply stationary and hidden according to a known distribution (e. g. , oil), or its motion is determined stochastically by known rules (e. g. , a fox in a forest). The problems dealt with in this book assume, on the contrary, that the “target” is an independent player of equal status to the Searcher, who cares about when he is found. We consider two possible motives of the target, and divide the book accordingly. Book I considers the zero-sum game that results when the target (here called the Hider) does not want to be found. Such problems have been called Search Games (with the “ze- sum” qualifier understood). Book II considers the opposite motive of the target, namely, that he wants to be found. In this case the Searcher and the Hider can be thought of as a team of agents (simply called Player I and Player II) with identical aims, and the coordination problem they jointly face is called the Rendezvous Search Problem.

Book Description
A daring and intimate new book by the poet and memoirist Nick Flynn, "a champion of contemporary American poetry" (Newpages) . . . the take from his bank jobs, all of it will come to me, if I can just get him to draw me a map, if I can find the tree, if I can find the shovel. And the house, the mansion he grew up in, soon a lawyer will pass a key across a walnut desk, but even this lawyer will not be able to tell me where this mansion is. —from "Kafka" In My Feelings, Nick Flynn makes no claims on anyone else's. These poems inhabit a continually shifting sense of selfhood, in the attempt to contain quicksilver realms of emotional energy—from grief and panic to gratitude and understanding.

'Where the twins had been a body lay in long, soft robes, and by its head a discarded lute. The head was split into halves from the apex of the skull to the nose'. Is this macabre scene only theatre, or a sign of ill omen? In the conclusion of the 'First Born of Egypt' saga, the fate of Conyngham, Marius Stern and other characters is decided.

Book Description
How is a subway map different from other maps? What makes a knot knotted? What makes the Möbius strip one-sided? These are questions of topology, the mathematical study of properties preserved by twisting or stretching objects. In the 20th century topology became as broad and fundamental as algebra and geometry, with important implications for science, especially physics. In this Very Short Introduction Richard Earl gives a sense of the more visual elements of topology (looking at surfaces) as well as covering the formal definition of continuity. Considering some of the eye-opening examples that led mathematicians to recognize a need for studying topology, he pays homage to the historical people, problems, and surprises that have propelled the growth of this field. ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area. These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

Book Description
Nick Mount is one of the world's leading glass artists. In his sixtieth year he was honoured with a major exhibition in Pittsburgh, Pennsylvania, as well as the Object Living Treasure Award. This book, written in the style of an extraordinary yarn, is not so much about Nick Mount's achievements as a glass artist as it is about the elements that have shaped his career and continue to inform his work. His philosophy, work ethic and environment, peers and family have all been factors in his work and success. Together they form the fabric of his work. Nick Mount has received numerous awards, including the Bavarian State Prize in Germany, an Australia Council Fellowship, and the Arts SA Triennial Project Grant. He acknowledges the honour of being able to work with his hands, and has enormous gratitude for a lifetime of assistance from Dr and Mrs G.J. Mount, Pauline, Hugo, Peta and Pip. Nick Mount The Fabric of Work is richly illustrated with photographs of Nick's pieces, including many made recently. These vibrant works range from the extraordinary flamboyant scent bottles to more recent wood and glass fruit pieces that reflect a lush quietude.

Book Description
Hideaway Self Storage, located just off Brisbane's M1, is in decline. But manager Ken Guy and his assistant Bruce carry on with their daily rituals even as the facility falls apart around them. Lately, however, certain tenants have been disappearing off the face of the earth, leaving behind units full of valuable items. Ken has no idea where these rent defaulters have gone but he thinks he might be able to turn their abandoned 'things' into a nice little earner that could help save his business. But the disappearances are accompanied by strange occurrences such as Bruce's inexplicable late-night excursions, Ken's intensifying aversion to fluorescent lights, and Ken's girlfriend's intensifying aversion to Ken. While further along the motorway, construction of a rival facility - Pharoah's Tomb Self Storage, part of a nationwide franchise - hints at a mysterious past and a precarious future. A surprisingly funny study of physical and mental deterioration, David Cohen's second novel is never quite what it seems. Sharply attuned to the absurdities of contemporary urban life, it is that rare literary beast, a comic drama that is at once intelligent and suspenseful, humorous and deep.
