Surface Diagnostics In Tribology: Fundamental Principles And Applications
This book provides final year undergraduate students, graduate students, research scientists and engineers with an up-to-date overview of the power of using surface analytical techniques for probing complex solid surfaces and lubricants as well as for understanding their interactions in tribological systems. The first three introductory chapters illustrate the need for surface analysis in tribology and the essentials of the analytical techniques. Following these, eight chapters on applications give insight into the contribution of the major analytical techniques to tribology. These chapters are divided into three groups. The first group deals with the applications of surface analytical techniques to the study of the adhesion, friction, deformation, wear, structure and chemistry of solid surfaces at the atomic scale or in well-defined conditions. The second group focuses mainly on solid lubricants and tribological surface modifications. Lastly, the third group covers liquid lubricants in molecularly thin-film lubrication and in boundary lubrication and their interactions with surfaces.
Advances in Microwave and Radio Frequency Processing
Prometheus brought fire to mankind Arthur R. von Hippel “Dielectrics and Waves”, 1954 Our contribution? There are only few areas of research and development of a comparable scientific and technological extension as microwave and high frequency processing. “Pr- essing” means not only application of radiation of 300 MHz to 300 GHz f- quency to synthesis, heating or ionisation of matter but also generation, transm- sion and detection of microwave and radio frequency radiation. Microwave and high frequency sources positioned in the orbit are the foun- tion of modern satellite telecommunication systems, gyrotron tubes being pr- ently developed in different countries all over the world wil...
Cosmic Rays at Earth
In 1912 Victor Franz Hess made the revolutionary discovery that ionizing radiation is incident upon the Earth from outer space. He showed with ground-based and balloon-borne detectors that the intensity of the radiation did not change significantly between day and night. Consequently, the sun could not be regarded as the sources of this radiation and the question of its origin remained unanswered. Today, almost one hundred years later the question of the origin of the cosmic radiation still remains a mystery.Hess' discovery has given an enormous impetus to large areas of science, in particular to physics, and has played a major role in the formation of our current understanding of universal ...
Studies on Eumalacostraca: a homage to Masatsune Takeda
This volume honours an outstanding Japanese carcinologist, Masatsune Takeda (National Museum of Nature and Science, Tokyo, Japan), on the occasion of his 70th birthday. Since 1967, Takeda-sensei (“sensei” is an honourific term for teacher or senior scientist in Japan) has devoted his life to studying the taxonomy of Brachyura and has published 323 papers over a long and illustrious career, and in the process, described 231 new taxa. In this volume, a total of 24 papers have been put together by 40 of his friends and colleagues to honour him. These papers cover a wide diversity of topics on the taxonomy, larval biology, palaeontology and ecology of Brachyura, Caridea, Stenopodidea, Astacidea, Axiidea, Anomura, Amphipoda, Isopoda and Mysida, all groups that Takeda-sensei loved.
Lubrication at the Frontier: The Role of the Interface and Surface Layers in the Thin Film and Boundary Regime
The 25th Leeds-Lyon Symposium on Tribology was held at the Institut des Sciences Appliquées de Lyon, from 8-11th September, 1998. Its central theme was, "Lubrication at the frontier: the role of the interface and surface layers in the thin film and boundary regime". This topic was chosen because it represents an important evolution of the research field.The Symposium opened with a keynote address entitled "Role of surface-anchored polymer chains in polymer friction" which described the processes taking place at the interface between "solid" and "liquid". The keynote address was followed by two invited lectures. Firstly, "Fuel efficient engine oils, additive interactions, boundary friction and wear" presented the industrial point of view on lubricant formulation and engine testing and its evolution. The second lecture was entitled "For establishment of a new EHL theory" and stressed the need to extend the current EHL theory.Beginning in 1974, The Leeds-Lyon Symposia have now covered a wide range of topics. The essential aim each year is to select a topic of current interest to tribologists and to contribute to further the advance of knowledge in selected fields.
Mathematical Modelling for Next-Generation Cryptography
This book presents the mathematical background underlying security modeling in the context of next-generation cryptography. By introducing new mathematical results in order to strengthen information security, while simultaneously presenting fresh insights and developing the respective areas of mathematics, it is the first-ever book to focus on areas that have not yet been fully exploited for cryptographic applications such as representation theory and mathematical physics, among others. Recent advances in cryptanalysis, brought about in particular by quantum computation and physical attacks on cryptographic devices, such as side-channel analysis or power analysis, have revealed the growing s...
Surface & Coatings Technology
Surface & Coatings Technology, Volume 61 presents the proceeding of the 20th International Conference on Metallurgical Coatings and Thin Films, held in San Diego, California, on April 19–23, 1993. This book discusses a variety of topics related to surface and coatings technology, including coatings for use at high temperature, hard coatings, and vapor deposition technology. Organized into 141 chapters, this compilation of papers begins with an overview of the coating requirements for long-life bucket protection, how each of these coating systems has performed, and the advantages and disadvantages of each. This text then discusses the gradient-free transition step achieved in the element analysis of the depth profiles. Other chapters consider the metastable yttrium oxide films that are synthesized using reactive sputter deposition. This book discusses as well the use of appropriate copper-based alloy coatings on structural components. The final chapter deals with the particle mechanical and thermal behavior in the process of high velocity oxy-fuel spraying. This book is a valuable resource for chemical engineers and metallurgists.

Boundary Element Methods
Significant developments in the boundary element method during the last two decades have made it a powerful alternative to the domain-type numerical methods of solution such as the finite element method. The advances made in the BEM are more or less due to the innovation of efficient computational techniques by introducing boundary elements for discretization of the boundary integral equations resulting from the so-called direct formulation. BEM has therefore become an efficient tool for optimal design and other inverse problems. These proceedings include discussion of the applications of BEM in mechanical engineering and the principles that have developed to make it an increasingly useful method of problem solving.
