This book brings together concepts and approaches from the fields of photogrammetry and computer vision. In particular, it examines techniques relating to quantitative image analysis, such as orientation, camera modelling, system calibration, self-calibration and error handling. The chapters have been contributed by experts in the relevant fields, and there are examples from automated inspection systems and other real-world cases. The book provides study material for students, researchers, developers and practitioners.

Space is devoid of the stuff humans need to live: air, gravity, hot showers, fresh veg, privacy, beer. How much can a person give up? What happens when you can't walk for a year? Is sex any fun in zero gravity? As Mary Roach discovers, it's possible to explore space without ever leaving Earth. From the space shuttle training toilet to a 17,000-mile-per-hour crash test of NASA's space capsule, she takes us on a surreally entertaining trip into the science of living in space.

"Introduction to Computational Science" was developed over a period of two years at the University of Utah Department of Computer Science in conjunction with the U.S. Department of Energy-funded Undergraduate Computation in Engineering Science (UCES) program. Each chapter begins by introducing a problem and then guiding the student through its solution. The computational techniques needed to solve the problem are developed as necassary, making the motivation for learning the computing alwasy apparent. Each chapter will introduce a single problem that will be used to motivate a single computing concept. The notes currently consist of 15 chapters. The first seven chapters deal with Maple and the last eight with C. The textbook will contain 20 to 30 chapters covering a similar mix of concepts at a finer level of detail.

(by) Sylvia Engdahl

A young woman is sent into danger on a planet poised on the brink of nuclear war, forbidden to interfere with its people's natural course of evolution or to reveal her alien origin. Her fellow-agent is not properly trained to work in the field and his compassion may lead him to intervene, thereby unintentionally bringing about the very disaster that he is trying desperately to prevent. She faces an agonizing choice: side with a renegade agent, ot stop him at any cost. Although this novel has the same heroine as *Enchantress from the Stars* it is not a sequel but a completely independent story not intended for readers below high school age. The 2003 edition contains significant updating and should be read in preference to earlier editions.
