When a government official dies on the operating table, the president calls in the computer cops On Venus, a radical exile escapes from a maximum-security prison, pledging to return to Washington and assassinate the president. Transport between Earth and the solar colonies is tightly regulated, but the exile knows a shortcut: the top-secret transvection machine, an experimental device that could theoretically be used to teleport men from planet to planet. Vander Defoe, the tool’s creator, is busy securing it when he feels a pain in his stomach: His appendix is about to explode. Defoe dies in the operating room during routine computerized surgery, and the case falls in the lap of the Computer Investigation Bureau, which has jurisdiction over all computer-related crimes. As the team tries to determine who corrupted the system that killed Defoe, it finds that in this case, all roads lead to Venus. The Transvectioon Machine is the first book in the Carl Crader Mysteries, but you may enjoy reading the series in any order.

This book provides the mathematical fundamentals of linear algebra to practicers in computer vision, machine learning, robotics, applied mathematics, and electrical engineering. By only assuming a knowledge of calculus, the authors develop, in a rigorous yet down to earth manner, the mathematical theory behind concepts such as: vectors spaces, bases, linear maps, duality, Hermitian spaces, the spectral theorems, SVD, and the primary decomposition theorem. At all times, pertinent real-world applications are provided. This book includes the mathematical explanations for the tools used which we believe that is adequate for computer scientists, engineers and mathematicians who really want to do serious research and make significant contributions in their respective fields.

A dozen marvelous tales of deduction, featuring history’s most famous detective, by Mystery Writers of America Grand Master Edward D. Hoch. In a heavily mortgaged country house, an heiress’s sinister guardian attempts to trap her in a bedroom with a rare Indian swamp adder—a murder averted only by the timely intervention of Sherlock Holmes. Five months after the events of “The Adventure of the Speckled Band,” Holmes and Watson are called back to Stoke Moran by a frightened traveler who claims that the viper has gotten loose again. Holmes is unsure which poses a greater danger: the rumored snake, or the possibility that the nomad is telling lies. In these dozen tales, short story master Edward D. Hoch resurrects the most brilliant mind in the history of detective fiction. In the style of Sir Arthur Conan Doyle, Holmes tangles with circus tigers, Druidic curses, and a pair of Christmas killings. Here is the finest detective of the Victorian age—recreated by one of the greatest mystery writers of the twentieth century.
