The classic minute-by-minute account of the sinking of the "Titanic," in a 50th anniversary edition with a new introduction by Nathaniel Philbrick
First published in 1955, "A Night to Remember" remains a completely riveting account of the "Titanic"'s fatal collision and the behavior of the passengers and crew, both noble and ignominious. Some sacrificed their lives, while others fought like animals for their own survival. Wives beseeched husbands to join them in lifeboats; gentlemen went taut-lipped to their deaths in full evening dress; and hundreds of steerage passengers, trapped below decks, sought help in vain.
Available for the first time in trade paperback and with a new introduction for the 50th anniversary edition by Nathaniel Phil-brick, author of "In the Heart of the Sea" and "Sea of Glory," Walter Lord's classic minute-by-minute re-creation is as vivid now as it was upon first publication fifty years ago. From the initial distress flares to the struggles of those left adrift for hours in freezing waters, this semicentennial edition brings that moonlit night in 1912 to life for a new generation of readers.

Localization for underwater robots remains a challenging issue. Typical sensors, such as Global Navigation Satellite System (GNSS) receivers, cannot be used under the surface and other inertial systems suffer from a strong integration drift. On top of that, the seabed is generally uniform and unstructured, making it difficult to apply Simultaneous Localization and Mapping (SLAM) methods to perform localization. Reliable Robot Localization presents an innovative new method which can be characterized as a raw-data SLAM approach. It differs from extant methods by considering time as a standard variable to be estimated, thus raising new opportunities for state estimation, so far underexploited. However, such temporal resolution is not straightforward and requires a set of theoretical tools in order to achieve the main purpose of localization. This book not only presents original contributions to the field of mobile robotics, it also offers new perspectives on constraint programming and set-membership approaches. It provides a reliable contractor programming framework in order to build solvers for dynamical systems. This set of tools is illustrated throughout this book with realistic robotic applications.

HYDRODYNAMIC PROPULSION AND ITS OPTIMIZATION ANALYTIC THEORY Hydrodynamic propulsion has been of major interest ever since craft took to the water. In the course of time, many attempts have been made to invent, develop, or to improve hydrodynamic propulsion devices. Remarkable achievements in this field were made essentially by experienced individuals, who were in need of reliable propulsion units such as paddle wheels, sculling devices, screw propellers, and of course, sails. The problem of minimizing the amount of input energy for a prescribed effective output was first investigated seriously at the beginning of this century. In 1919, BETZ presented a paper on air-screw propellers with minimum consumption of energy which could be applied to ship-screw propellers also. Next, attempts were made to optimize hydrodynamic propulsion units. Ensuing investigations concerned the optimization of the hydrodynamic system: ship-propeller. The first simple theory of ship propulsion which was presented considered more or less only thrust augmentation, wake processing and modification of propeller characteristics when operating behind the ships hull. This theory has been little improved meanwhile and is still useful, particularly with regard to practical ship design and for evaluating results of ship model tests. However, this theory is not adequate for optimization procedures necessary for high-technology propulsion, particularly for ship propellers utilizing propulsion improving devices such as tip end plates or tip fins at the propeller blades, spoilers in front of the propeller, asymmetrical stern etc.
