Book Synopsis Fusion of Defects by : Arthur Bartels
Download or read book Fusion of Defects written by Arthur Bartels and published by American Mathematical Soc.. This book was released on 2019-04-10 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conformal nets provide a mathematical model for conformal field theory. The authors define a notion of defect between conformal nets, formalizing the idea of an interaction between two conformal field theories. They introduce an operation of fusion of defects, and prove that the fusion of two defects is again a defect, provided the fusion occurs over a conformal net of finite index. There is a notion of sector (or bimodule) between two defects, and operations of horizontal and vertical fusion of such sectors. The authors' most difficult technical result is that the horizontal fusion of the vacuum sectors of two defects is isomorphic to the vacuum sector of the fused defect. Equipped with this isomorphism, they construct the basic interchange isomorphism between the horizontal fusion of two vertical fusions and the vertical fusion of two horizontal fusions of sectors.

Book Synopsis A Practical Guide to Welding Solutions by : Robert W. Messler, Jr.
Download or read book A Practical Guide to Welding Solutions written by Robert W. Messler, Jr. and published by John Wiley & Sons. This book was released on 2019-04-29 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: As critically important as welding is to a wide spectrum of manufacturing, construction, and repair, it is not without its problems. Those dependent on welding know only too well how easy it is to find information on the host of available processes and on the essential metallurgy that can enable success, but how frustratingly difficult it can be to find guidance on solving problems that sooner or later arise with welding, welds, or weldments. Here for the first time is the book those that practice and/or depend upon welding have needed and awaited. A Practical Guide to Welding Solutions addresses the numerous technical and material-specific issues that can interfere with success. Renowned industrial and academic welding expert and prolific author and speaker Robert W. Messler, Jr. guides readers to the solutions they seek with a well-organized search based on how a problem manifests itself (i.e., as distortion, defect, or appearance), where it appears (i.e., in the fusion zone heat-affected zone, or base metal), or it certain materials or situations.

Available in PDF, EPUB and Kindle. Book excerpt: This book addresses various aspects of ship construction, from ship types and construction materials, to welding technologies and accuracy control. The contents of the book are logically organized and divided into twenty-one chapters. The book covers structural arrangement with longitudinal and transverse framing systems based on the service load, and explains basic structural elements like hatch side girders, hatch end beams, stringers, etc. along with structural subassemblies like floors, bulkheads, inner bottom, decks and shells. It presents in detail double bottom construction, wing tanks & duct keels, fore & aft end structures, etc., together with necessary illustrations. The midship sections of various ship types are introduced, together with structural continuity and alignment in ship structures. With regard to construction materials, the book discusses steel, aluminum alloys and fiber reinforced composites. Various methods of steel material preparation are discussed, and plate cutting and forming of plates and sections are explained. The concept of line heating for plate bending is introduced.Welding power source characteristics, metal transfer mechanisms, welding parameters and their effects on the fusion zone, weld deposit, and weld bead profile are discussed in detail. Various fusion welding methods, MMAW, GMAW, SAW, Electroslag welding and Electrogas welding and single side welding are explained in detail. Friction stir welding as one of the key methods of solid state welding as applied to aluminum alloys is also addressed. The mechanisms of residual stress formation and distortion are explained in connection with stiffened panel fabrication, with an emphasis on weld induced buckling of thin panels. Further, the basic principles of distortion prevention, in-process distortion control and mitigation techniques like heat sinking, thermo-mechanical tensioning etc. are dealt with in detail. In its final section, the book describes in detail various types of weld defects that are likely to occur, together with their causes and remedial measures. The nondestructive testing methods that are most relevant to ship construction are explained. Lastly, a chapter on accuracy control based on statistical principles is included, addressing the need for a suitable mechanism to gauge the ranges of variations so that one can quantitatively target the end product accuracy.

The book then focuses on specific organs andreviews the cellular and molecular mechanisms affecting theirdevelopment and how disruption of these mechanisms by genetic orenvironmental factors may underlie certain birth defects. Thechapters are concise and provide up-to-date coverage of topics in aformat that is easily accessible and yet at the forefront ofresearch. Written primarily for paediatricians, obstetricians, clinicalgeneticists and allied workers, this book guides the reader throughthe contribution of modern molecular biology to our understandingof human development. Developmental and cellular biologists willlearn how errors in the cellular and genetic mechanism can lead toclassical disorders, diseases and syndromes.

Book Synopsis Charged Semiconductor Defects by : Edmund G. Seebauer
Download or read book Charged Semiconductor Defects written by Edmund G. Seebauer and published by Springer Science & Business Media. This book was released on 2008-11-14 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: Defects in semiconductors have been studied for many years, in many cases with a view toward controlling their behaviour through various forms of “defect engineering”. For example, in the bulk, charging significantly affects the total concentration of defects that are available to mediate phenomena such as solid-state diffusion. Surface defects play an important role in mediating surface mass transport during high temperature processing steps such as epitaxial film deposition, diffusional smoothing in reflow, and nanostructure formation in memory device fabrication. “Charged Defects in Semiconductors” details the current state of knowledge regarding the properties of the ionized defects that can affect the behaviour of advanced transistors, photo-active devices, catalysts, and sensors. Features: group IV, III-V, and oxide semiconductors; intrinsic and extrinsic defects; and, point defects, as well as defect pairs, complexes and clusters.
