Leonardo DaVinci was revered for his technical ingenuity and love of engineering. During his lifetime, he managed to produce some 13,000 pages of diagrams, drawings, and notes which combined art and science. He devised many contraptions and engineering wonders ahead of his time, and many which could not be built with the materials and science of the day, including hydraulic pumps, crank mechanisms, and even a steam cannon.

Autodesk today announced that it has reached a key milestone in its integration of recently acquired Algor software with the release of the Autodesk Algor Simulation 2010 products. A key component of the Autodesk solution for Digital Prototyping, Autodesk Algor Simulation software provides a broad range of mechanical simulation tools to help designers and engineers make critical decisions earlier in the design process.

Description : The roots of micro/nanotribology can be found deep in conventional concepts of tribology. The recognition in the last century of elasto-hydrodynamic lubrication EHL as the principal mode of fluid-film lubrication in many machine components enabled reliable design procedures to be developed for both highly stressed and low elastic modulus machine elements. Towards the end of the last century submicron film thicknesses were recognized in many EHL applications. It is now being asked how EHL concepts can contribute to understanding the behavior of even thinner lubricating films. The answer is to be found in the subject widely known as micro/nanotribology. As early as 1929 Tomlinson considered the origin of friction and the mechanism of energy dissipation in terms of an independent oscillator model. This import ant approach provided the foundation for many present studies of atomic scale friction. The rapid development of micro/nanotribology in recent decades is certainly a significant and fascinating aspect of modern tribology. New scientific instruments, impressive modeling, and computer simulations have contributed to the current fascination with nanotechnology. A remarkable indication of these developments is evident in the boom of publications. Nevertheless, the knowledge and understanding of micro/nanotribology remains incomplete, although several books related to the subject have now been published. The interdisciplinary nature of tribology persists in studies of microscopic scale tribology. Individual investigators contribute to specific aspects of the field as they help to develop a general picture of the new field of micro/nanotribology, thus adding additional bricks to the house of truth. The present book is written by authors whose backgrounds are mainly in mechan ical engineering. They present individual contributions to the development of microscopic tribology, with significant effort being made to form a bridge between fundamental studies and applications.

Engineering and physics students quickly learn that solving problems depends as much on problem-solving skills as it does on subject-based knowledge. Students with such skills not only perform better on homework and tests but learn the subject matter more effectively.

Calculus II is a prerequisite for many popular college majors, including pre-med, engineering, and physics. Calculus II For Dummies offers expert instruction, advice, and tips to help second semester calculus students get a handle on the subject and ace their exams. It covers intermediate calculus topics in plain English, featuring in-depth coverage of integration, including substitution, integration techniques and when to use them, approximate integration, and improper integrals. This hands-on guide also covers sequences and series, with introductions to multivariable calculus, differential equations, and numerical analysis. Best of all, it includes practical exercises designed to simplify and enhance understanding of this complex subject.

"This book is fast becoming the standard text in its field", wrote a reviewer in the Journal of Canadian Petroleum Technology soon after the first appearance of Dake's book. This prediction quickly came true: it has become the standard text and has been reprinted many times. The author's aim - to provide students and teachers with a coherent account of the basic physics of reservoir engineering - has been most successfully achieved. No prior knowledge of reservoir engineering is necessary. The material is dealt with in a concise, unified and applied manner, and only the simplest and most straightforward mathematical techniques are used. This low-priced paperback edition will continue to be an invaluable teaching aid for years to come.
