Desulfurization of Hot Coal Gas (Nato ASI Subseries G: #42)

by Aysel T. Atimtay Douglas P. Harrison

Economic and environmental requirements for advanced power generating systems demand the removal of corrosive and other sulfurous compounds from hot coal gas. After a brief account of the world energy resources and an overview of clean coal technologies, a review of regenerable metal oxide sorbents for cleaning the hot gas is provided. Zinc oxide, copper oxide, calcium oxide, manganese oxide based as well as supported and mixed metal oxide sorbents are treated. Performance analysis of these sorbents, effects of various parameters on the desulfurization efficiency, kinetics of sulfidation and regeneration reactions, sulfiding and regeneration mechanisms are discussed. Two chapters present recent results in the direct production of elemental sulfur from regeneration or SO2-rich gases.

The Destroyer USS Kidd (Anatomy of The Ship)

by Stefan Draminski

A brilliantly detailed visual representation of the only US World War II destroyer to have retained its original configuration.Superbly illustrated with artwork of the ship through its career, reconstructions of deck layouts, and 3D illustrations of every detail of the ship from its rigging to its boats to its anchors, this book reconstructs and dissects the Fletcher-class destroyer USS Kidd, the most original survivor of the US Navy's most famous class of World War II destroyers. Kidd fought throughout the Pacific War, in the Marshall Islands, Marianas, and Philippines campaigns. In early 1945, Kidd joined Task Force 58 for the invasion of Okinawa, and postwar served in the Korean War. Since 1982 USS Kidd has been a museum ship at Baton Rouge, Louisiana.Drawing on Stefan Draminski's new research and making the best use yet of his acclaimed 3D illustration techniques, this is the most comprehensive examination of USS Kidd ever published. It includes a complete set of detailed line drawings with fully descriptive keys and full-color 3D artwork, supported by technical details, photographs, and a concise history of the ship's construction and service.

Despeckling Methods for Medical Ultrasound Images

by Ju Zhang Yun Cheng

Based upon the research they have conducted over the past decade in the field of denoising processes for medical ultrasonic imaging, in this book, the authors systematically present despeckling methods for medical ultrasonic images. Firstly, the respective methods are reviewed and divided into five categories. Secondly, after introducing some basic mathematical tools such as wavelet and shearlet transforms, the authors highlight five recently developed despeckling methods for medical ultrasonic images. In turn, simulations and experiments for clinical ultrasonic images are presented for each method, and comparison studies with other well-known existing methods are conducted, showing the effectiveness and superiority of the new methods. Students and researchers in the field of signal and image processing, as well as medical professionals whose work involves ultrasonic diagnosis, will greatly benefit from this book. Familiarizing them with the state of the art in despeckling methods for medical ultrasonic images, it offers a useful reference guide for their study and research work.

Despeckle Filtering for Ultrasound Imaging and Video, Volume II: Selected Applications, Second Edition (Synthesis Lectures on Algorithms and Software in Engineering)

by Christos P. Loizou Constantinos S. Pattichis

In ultrasound imaging and video visual perception is hindered by speckle multiplicative noise that degrades the quality. Noise reduction is therefore essential for improving the visual observation quality or as a pre-processing step for further automated analysis, such as image/video segmentation, texture analysis and encoding in ultrasound imaging and video. The goal of the first book (book 1 of 2 books) was to introduce the problem of speckle in ultrasound image and video as well as the theoretical background, algorithmic steps, and the MatlabTM for the following group of despeckle filters: linear despeckle filtering, non-linear despeckle filtering, diffusion despeckle filtering, and wavelet despeckle filtering. The goal of this book (book 2 of 2 books) is to demonstrate the use of a comparative evaluation framework based on these despeckle filters (introduced on book 1) on cardiovascular ultrasound image and video processing and analysis. More specifically, the despeckle filtering evaluation framework is based on texture analysis, image quality evaluation metrics, and visual evaluation by experts. This framework is applied in cardiovascular ultrasound image/video processing on the tasks of segmentation and structural measurements, texture analysis for differentiating between two classes (i.e. normal vs disease) and for efficient encoding for mobile applications. It is shown that despeckle noise reduction improved segmentation and measurement (of tissue structure investigated), increased the texture feature distance between normal and abnormal tissue, improved image/video quality evaluation and perception and produced significantly lower bitrates in video encoding. Furthermore, in order to facilitate further applications we have developed in MATLABTM two different toolboxes that integrate image (IDF) and video (VDF) despeckle filtering, texture analysis, and image and video quality evaluation metrics. The code for these toolsets is open source and these are available to download complementary to the two monographs.

Despeckle Filtering for Ultrasound Imaging and Video, Volume I: Algorithms and Software, Second Edition (Synthesis Lectures on Algorithms and Software in Engineering)

by Christos P. Loizou Constantinos S. Pattichis

It is well known that speckle is a multiplicative noise that degrades image and video quality and the visual expert's evaluation in ultrasound imaging and video. This necessitates the need for robust despeckling image and video techniques for both routine clinical practice and tele-consultation. The goal for this book (book 1 of 2 books) is to introduce the problem of speckle occurring in ultrasound image and video as well as the theoretical background (equations), the algorithmic steps, and the MATLABTM code for the following group of despeckle filters: linear filtering, nonlinear filtering, anisotropic diffusion filtering, and wavelet filtering. This book proposes a comparative evaluation framework of these despeckle filters based on texture analysis, image quality evaluation metrics, and visual evaluation by medical experts. Despeckle noise reduction through the application of these filters will improve the visual observation quality or it may be used as a pre-processing step for further automated analysis, such as image and video segmentation, and texture characterization in ultrasound cardiovascular imaging, as well as in bandwidth reduction in ultrasound video transmission for telemedicine applications. The aforementioned topics will be covered in detail in the companion book to this one. Furthermore, in order to facilitate further applications we have developed in MATLABTM two different toolboxes that integrate image (IDF) and video (VDF) despeckle filtering, texture analysis, and image and video quality evaluation metrics. The code for these toolsets is open source and these are available to download complementary to the two books.

Despeckle Filtering Algorithms and Software for Ultrasound Imaging (Synthesis Lectures on Algorithms and Software in Engineering)

by Christos Loizou Constantinos Pattichis

It is well-known that speckle is a multiplicative noise that degrades image quality and the visual evaluation in ultrasound imaging. This necessitates the need for robust despeckling techniques for both routine clinical practice and teleconsultation. The goal for this book is to introduce the theoretical background (equations), the algorithmic steps, and the MATLAB™ code for the following group of despeckle filters: linear filtering, nonlinear filtering, anisotropic diffusion filtering and wavelet filtering. The book proposes a comparative evaluation framework of these despeckle filters based on texture analysis, image quality evaluation metrics, and visual evaluation by medical experts, in the assessment of cardiovascular ultrasound images recorded from the carotid artery. The results of our work presented in this book, suggest that the linear local statistics filter DsFlsmv, gave the best performance, followed by the nonlinear geometric filter DsFgf4d, and the linear homogeneous mask area filter DsFlsminsc. These filters improved the class separation between the asymptomatic and the symptomatic classes (of ultrasound images recorded from the carotid artery for the assessment of stroke) based on the statistics of the extracted texture features, gave only a marginal improvement in the classification success rate, and improved the visual assessment carried out by two medical experts. A despeckle filtering analysis and evaluation framework is proposed for selecting the most appropriate filter or filters for the images under investigation. These filters can be further developed and evaluated at a larger scale and in clinical practice in the automated image and video segmentation, texture analysis, and classification not only for medical ultrasound but for other modalities as well, such as synthetic aperture radar (SAR) images.

Desorption Induced by Electronic Transitions DIET V: Proceedings of the Fifth International Workshop, Taos, NM, USA, April 1–4, 1992 (Springer Series in Surface Sciences #31)

by Alan R. Burns Ellen B. Stechel Dwight R. Jennison

This volume in the Springer Series on Surface Sciences presents a recent account of advances in the ever-broadening field of electron-and photon-stimulated sur­ face processes. As in previous volumes, these advances are presented as the proceedings of the International Workshop on Desorption Induced by Electronic Transitions; the fifth workshop (DIET V) was held in Taos, New Mexico, April 1-4, 1992. It will be abundantly clear to the reader that "DIET" is not restricted to desorption, but has for several years included photochemistry, non-thermal surface modification, exciton self-trapping, and many other phenomena that are induced by electron or photon bombardment. However, most stimulated surface processes do share a common physics: initial electronic excitation, localization of the excitation, and conversion of electronic energy into nuclear kinetic energy. It is the rich variation of this theme which makes the field so interesting and fruitful. We have divided the book into eleven parts in order to emphasize the wide range of materials that are examined and to highlight recent experimental and theoretical advances. Naturally, there is considerable overlap between sections, and many papers would be appropriate in more than one part. Part I focuses on perhaps the most active area in the field today: electron attachment. Here the detection and characterization of negative ions formed by attachment of elec­ trons supplied externally from the vacuum are discussed. In addition, the first observations of negative ions formed by substrate photoelectrons are presented.

Desorption Induced by Electronic Transitions DIET II: Proceedings of the Second International Workshop, Schloß Elmau, Bavaria, October 15–17, 1984 (Springer Series in Surface Sciences #4)

by Wilhelm Brenig Dietrich Menzel

The second workshop on Desorption Induced by Electronic Transitions (DIET II) took place October 15-17, 1984, in SchloB Elmau, Bavaria. DIET II, fol­ lowing the great success of DIET I (edited by N. H. Tolk, M. M. Traum, J. C. Tully, T. E. Madey and published in Springer Ser. Chem. Phys. , Vol. 24), again brought together over 60 workers in this exciting field. The "hard co­ re of experts" was essentially the same as in DIET I but the general overlap of participants between the two meetings was small. While DIET I had the function of an exposition of the status of the field DIET II focussed more on new developments. The main emphasis was again on the microscopic under­ standing of DIET but a number of side aspects and the application of DIET ideas to other fields such as sputtering, laser-induced desorption, fractu­ re, erosion, etc. were considered, too. New mechanisms and new refined expe­ rimental techniques were proposed and discussed at the meeting critically but with great enthusiasm. In addition to the talks, there was a continuous poster exhibition which also stimulated extended and excited discussions. This book is a collection of papers summarizing the talks and posters presented at the meeting.

Desorption Induced by Electronic Transitions DIET I: Proceedings of the First International Workshop, Williamsburg, Virginia, USA, May 12–14, 1982 (Springer Series in Chemical Physics #24)

by N. H. Tolk M. M. Traum J. C. Tully T. E. Madey

The Workshop on Desorption Induced by Electronic Transitions (DIET) took place May 12-14, 1982, in Williamsburg, Virginia. The meeting brought together, for the first time, most of the leading workers in the fields of electron and photon stimulated desorption from surfaces, as well as many workers in related fields, including sputtering, gas-phase photodissociation and solid-state theory. The emphasis of the workshop was on the microscopic mechanism of stimu­ lated desorption. Many possible mechanisms have been proposed, and a few new ones emerged at the meeting. Though no consensus was reached, many views were espoused and criticized, frequently with considerable enthusiasm. The result was an appraisal of our current understanding of DIET, and a focus on the experimental and theoretical efforts most likely to lead to new insights. This volume is an attempt to record the information exchanged in this very successful workshop and, perhaps, convey some of the excitement of the field of DIET. The book is a collection of papers written by participants in the DIET workshop, including in addition a contribution from Dietrich Menzel, who was unable to attend. Thus, this book represents a complete statement of the state of the art of experimental and theoretical studies of DIET and related phenomena. More importantly, it addresses the interesting unsolved problems, and suggests strategies for unraveling them. We acknowledge the assistance given by the other members of the organizing committee, A. E. de Vries, R. Gomer, M. L. Knotek, D. Menzel and D. P.

Designs for Science Literacy

by American Association for the Advancement of Science

The call for science curriculum reform has been made over and over again for much of the twentieth century. Arguments have been made that the content of the curriculum is not appropriate for meeting the individual and social needs of people living in the modern world; that the curriculum has become overstuffed with topics and does not serve students especially well; and above all, that the curriculum does not generate the student learning it is expected to produce. The latest volume in a continuing series of publications from the AAAS designed to reform science education, Designs for Science Literacy presupposes that curriculum reform must be considerably more extensive and fundamental than the tinkering with individual courses and subjects that has been going on for decades. Designs deals with the critical issues involved in assembling sound instructional materials into a new, coherent K-12 whole. The book pays special attention to the need to link science-oriented studies to the arts and humanities, and also proposes how to align the curriculum with an established set of learning goals while preserving the American tradition of local responsibility for the curriculum itself. If fundamental curriculum reform is ever to occur, a new process for creating alternatives will have to be developed. Designs for Science Literacy provides the groundwork for such a process.

Designing with the Wind: Climate-Derived Architecture (Digital Innovations in Architecture, Engineering and Construction)

by Lenka Kabošová Dušan Katunský Stanislav Kmeť

This book explores wind-adaptive architectural design blending the parametric design with digital simulations and suggests a novel approach for specific, even extreme conditions, as the first step in creating architecture that can act in response to the nature around. The chapters propose an urban and architectural design that emerges from the specific wind microclimate of the design site and responds to the changes in the ambient wind conditions. The book looks closely at A) the interdisciplinary wind-driven design method for architects, engineers, and urbanists employing open-source software for CFD analysis and B) the tensegrity-membrane adaptive building façades. The main questions the authors try to answer are: How does the wind-driven methodology enhance the wind comfort around buildings? How can it contribute to the reduction of wind surface loads acting on buildings?

Designing with Structural Ceramics

by R. W. Davidge M. H. Van De Voorde

The last 30 years have seen a steady development in the range of ceramic materials with potential for high temperature engineering applications: in the 60s, self-bonded silicon carbide and reaction-bonded silicon nitride; in the 70s, improved aluminas, sintered silicon carbide and silicon nitrides (including sialons); in the 80s, various toughened Zr0 materials, ceramic matrix composites reinforced with silicon 2 carbide continuous fibres or whiskers. Design methodologies were evolved in the 70s, incorporating the principles of fracture mechanics and the statistical variation and time dependence of strength. These have been used successfully to predict the engineering behaviour of ceramics in the lower range of temperature. In spite of the above, and the underlying thermodynamic arguments for operations at higher temperatures, there has been a disappointing uptake of these materials in industry for high temperature usc. Most of the successful applications are for low to moderate temperatures such as seals and bearings, and metal cutting and shaping. The reasons have been very well documented and include: • Poor predictability and reliability at high temperature. • High costs relative to competing materials. • Variable reproducibility of manufacturing processes. • Lack of sufficiently sensitive non-destructive techniques. With this as background, a Europhysics Industrial Workshop sponsored by the European Physical Society (EPS) was organised by the Netherlands Energy Research Foundation (ECN) and the Institute for Advanced Materials of the Joint Research Centre (JRC) of the EC, at Petten, North Holland, in April 1990 to consider the status of thermomechanical applications of engineering ceramics.
