Diamond has a unique combination of properties, such as the highest hardness and thermal conductivity among any known material, high electrical resistivity, a large optical band gap and a high transmission, good resistance to chemical erosion, low adhesion and friction, and extremely low thermal expansion coefficient. As such, diamond has been a desirable material in a wide range of applications in mechanical, chemical, optical, thermal and electrical engineering. In many of the cases, the surface of a diamond component or element must have a superior finish, often down to a surface roughness of nanometers. Nevertheless, due to its extreme hardness and chemical inertness, the polishing of diamond and its composites has been a sophisticated process. Polishing of Diamond Materials will provide a state-of-the-art analysis, both theoretically and experimentally, of the most commonly used polishing techniques for mono/poly-crystalline diamond and chemical vapour deposition (CVD) diamond films, including mechanical, chemo-mechanical, thermo-chemical, high energy beam, dynamic friction and other polishing techniques. The in-depth discussions will be on the polishing mechanisms, possible modelling, material removal rate and the quality control of these techniques. A comparison of their advantages and drawbacks will be carried out to provide the reader with a useful guideline for the selection and implementation of these polishing techniques. Polishing of Diamond Materials will be of interest to researchers and engineers in hard materials and precision manufacturing, industry diamond suppliers, diamond jewellery suppliers and postgraduate students in the area of precision manufacturing.

Failure of components or systems must be prevented by both designers and operators of systems, but knowledge of the underlying mechanisms is often lacking. Since the relation between the expected usage of a system and its failure behavior is unknown, unexpected failures often occur, with possibly serious financial and safety consequences. Principles of Loads and Failure Mechanisms. Applications in Maintenance, Reliability and Design provides a complete overview of all relevant failure mechanisms, ranging from mechanical failures like fatigue and creep to corrosion and electric failures. Both qualitative and quantitative descriptions of the mechanisms and their governing loads enable a solid assessment of a system's reliability in a given or assumed operational context. Moreover, a unique range of applications of this knowledge in the fields of maintenance, reliability and design are presented. The benefits of understanding the physics of failure are demonstrated for subjects like condition monitoring, predictive maintenance, prognostics and health management, failure analysis and reliability engineering. Finally, the role of these mechanisms in design processes and design for maintenance are illustrated.

Excerpt: ... APPENDIX (B). Abstract of Evidence and Reports made by a Select Com? mittee of the House of Commons, on Steam Engines and Furnaces. MICHAEL ANGELO TAYLOR, ESQ, In the Chair. Mr. Joseph Gregson, Surveyor, called in and examined. Was of opinion that the nuisance that arose from the smoke of steam engine furnaces might be attributed to two causes: one, the putting on the fire or furnace too much crude fuel at one time; the other, from the chimnies being commonly too low, in proportion to the fuel consumed.--Had seen this nuisance effectually removed; but it had generally been attended with an increased consumption of fuel: it was seldom adopted but where the parties had been or were under an indictment.--His own invention consisted in, causing all the smoke after it had arisen from the fire, to return into the heat of the fire before it entered into the flue or chimney, and so was consumed; 2dly, By putting on no more fuel at any one time than the smoke of which can be so consumed, and that without opening the furnace door for the purpose; 3dly, By supplying every fire with air, in order to counteract the effect of those winds that operate against the draft.--Had employed it in the fires and boilers of private houses, under steam engine boilers, and in wealding furnaces, where a number of bits and scraps of iron were packed together, and subjected to an intense heat 3 they were, in that state, then rolled or hammered into one compact body.--The result however in the latter case was, that although every thing acted according to the plans laid down, and the fire was regularly supplied with fuel, and the smoke completely destroyed, yet the heat necessary to weald those scraps of iron together could never be attained, and this was in consequence of the continued...

Every four years, Schaeffler provides an insight into its latest developments and technologies from the engine, transmission and chassis as well as hybridization and electric mobility sectors. In 2014 the Schaeffler Symposium with the motto "Solving the Powertrain Puzzle" took place from 3th to 4th of April in Baden-Baden. Mobility for tomorrow is the central theme of this proceeding. The authors are discussing the different requirements, which are placed on mobility in different regions of the world. In addition to the company's work in research and development, a comprehensive in-house mobility study also provides a reliable basis for the discussion. The authors are convinced that there will be a paradigm shift in the automotive industry. Issues such as increasing efficiency and advancing electrification of the powertrain, automatic and semi-automatic driving, as well as integration in information networks will define the automotive future. In addition, the variety of solutions available worldwide will become increasingly more complex and mobility patterns will also change rapidly. However, this does not mean that cars will drive virtually in the future. Powertrains based on internal combustion engines will still dominate for a very long time and demonstrate new strengths in combination with hybrid drives. Transmissions will also gain in importance as the link between the internal combustion engine and electric motor. The proceeding "Solving the Powertrain Puzzle" contains 34 technical papers from renowned experts and researchers in the field of automotive engineering.

Following distinguished service during the Napoleonic Wars, the Scottish naval officer and Arctic explorer Sir John Ross (1777 1856) embarked on an abortive expedition to discover the North-West Passage. The existence of the Croker mountains, which he claimed had blocked his path, was afterwards disputed and his reputation suffered. His 1819 account of that voyage has been reissued in the Cambridge Library Collection. Prior to setting out in a steam vessel on a second expedition, for which he would be knighted, Ross published the present work in 1828. Seeking to establish himself as an authority on steam power when the technology was still in its infancy, Ross explores the development of the steam engine, the commercial and military potential of steam navigation, and how this called for a radical change in naval tactics. Illustrated throughout, this is the work of a practical maritime mind, combining both historical and technical detail.
