Understanding how gears are formed and how they interact or ‘mesh’ with each other is essential when designing equipment that uses gears or gear trains. The way in which gear teeth are formed and how they mesh is determined by their geometry and kinematics, which is the topic of this book.
Gears and Gear Drives provides the reader with comprehensive coverage of gears and gear drives. Spur, helical, bevel, worm and planetary gears are all covered, with consideration given to their classification, geometry, kinematics, accuracy control, load capacity and manufacturing. Cylindrical gear geometry is the basis for dealing with any gear drives, so this is covered in detail.

The new edition of this book greatly updates and expands the previous edition. It boasts new chapters on the divided wall column and carbon dioxide capture from stack gas, revises the design and control of distillation systems, and explains the use of dynamic simulation to study safety issues in the event of operating failures. Using Aspen Plus to develop rigorous simulations of single distillation columns and sequences of columns, the book considers the economics of capital investment and energy costs to create an optimal system for separation methods in the chemical and petroleum industries.
There are a large number of books available on fuel cells; however, the majority are on specific types of fuel cells such as solid oxide fuel cells, proton exchange membrane fuel cells, or on specific technical aspects of fuel cells, e.g., the system or stack engineering. Thus, there is a need for a book focused on materials requirements in fuel cells. Key Materials in High-Temperature Fuel Cells is a concise source of the most important and key materials and catalysts in high-temperature fuel cells with emphasis on the most important solid oxide fuel cells. A related book will cover key materials in low-temperature fuel cells. The two books form part of the ?Materials for Sustainable Energy & Development? series.Key Materials in High-Temperature Fuel Cells brings together world leaders and experts in this field and provides a lucid description of the materials assessment of fuel cell technologies. With an emphasis on the technical development and applications of key materials in high-temperature fuel cells, this text covers fundamental principles, advancement, challenges, and important current research themes. Topics covered include: advanced anodes for hydrogen and hydrocarbon fuels; oxide ion conducting materials for electrolytes; metallic interconnect materials of solid oxide fuel cells; materials and design for micro-SOFCs; advanced cathodes of solid oxide fuel cells; materials and processing for metal-supported solid oxide fuel cells; degradation and poisoning issues of electrode materials of solid oxide fuel cells, status and challenges in molten carbonate fuel cells; and key materials in direct carbon and phosphoric acid fuel cellsThis book is an essential reference source for researchers, engineers and technicians in academia, research institutes and industry working in the fields of fuel cells, energy materials, electrochemistry and materials science and engineering.
As it was shown in the design set up, the design project contains some parts of typical plant unit operations that could be designed by the given data's. In this paper the design analysis begins from the distillation column, by collecting data's such as the vapor liquid equilibrium of the mixture and the physical properties of the mixture from chemical engineering handbooks [Perry].The McCabe Thiele method is used to determine the number of theoretical stages by plotting the operating and stripping line .The column diameter, perforations and tray spacing also designed.
Next, the heat exchanger design was done (U-tube) for heating purpose. By using a steam as a heating media and the type of material of construction, tube side and shell side pressure drops, generally thermal and mechanical designs is done. Similar procedure was followed for heat exchanger two (condenser).
Prior extrusion books are based on barrel rotation physics-this is the first book that focuses on the actual physics of the process-screw rotation physics. In the first nine chapters, theories and math models are developed. Then, these models are used to solve actual commercial problems in the remainder of the book. Realistic case studies are presented that are unique in that they describe the problem as viewed by a typical plant engineer and provide the actual dimensions of the screws. Overall, there is not a book on the market with this level of detail and disclosure. The new knowledge in this book will be highly useful for production engineers, technical service engineers working with customers, consultants specializing in troubleshooting and process design, and process researchers and designers that are responsible for processes that running at maximum rates and maximum profitability.Contents:oIntroduction & TroubleshootingoPolymer MaterialsoIntroduction to Polymer Rheology for ExtrusionoResin Physical Properties Related to ProcessingoSolids ConveyingoThe Melting ProcessoFluid Flow in Metering ChannelsoMixing Processes for Single-Screw Extruders oScaling of Single-Screw Extrusion ProcessesoIntroduction to Troubleshooting the Extrusion ProcessoContaminations in the Finished ProductoFlow Surging oRate-Limited Extrusion Processes oBarrier and High-Performance ScrewsoMelt-Fed Extruders
Originally published in 1968, Harry Van Trees’s Detection, Estimation, and Modulation Theory, Part I is one of the great time-tested classics in the field of signal processing. Highly readable and practically organized, it is as imperative today for professionals, researchers, and students in optimum signal processing as it was over thirty years ago. The second edition is a thorough revision and expansion almost doubling the size of the first edition and accounting for the new developments thus making it again the most comprehensive and up-to-date treatment of the subject.
With a wide range of applications such as radar, sonar, communications, seismology, biomedical engineering, and radar astronomy, among others, the important field of detection and estimation has rarely been given such expert treatment as it is here. Each chapter includes section summaries, realistic examples, and a large number of challenging problems that provide excellent study material. This volume which is Part I of a set of four volumes is the most important and widely used textbook and professional reference in the field.
Focusing on imaging aspects of bistatic Synthetic Aperture Radar (SAR) signal processing, this book covers resolution analysis, echo generation methods, imaging algorithms, imaging parameter estimation, and motion compensation methods. The book is ideal for researchers and engineers in SAR signal and data processing, as well as those working in bistatic and multistatic radar imaging, and in the radar sciences. Graduate students with a background in radar who are interested in bistatic and multistatic radar will find this book a helpful reference.
Processors and users of plastics often need to determine the chemical nature of a plastics specimen. This highly practical and useful manual, now in a fifth revised and supplemented edition, will enable you to determine the class of plastic of a particular specimen. No extensive knowledge of chemistry is required and yet it is more complex than a simple tabular compilation. This manual is a handy and highly effective tool for many practical situations. An additional supplement is a chapter that shows strategies for identifying historical plastic objects; this is of particular interest for assemblers and collectors, and conservators.Prof. Dr. Dietrich Braun was the director of the plastics institute (Deutschen Kunststoff-Instituts (DKI)) in Darmstadt until 2000. He is also the author of many reference books and textbooks. For years, Dr. Braun has chaired workshops in plastics technology for business people as well as for first-time users, which is the basis for this book.
A timely publication providing coverage of radio resource management, mobility management and standardization in heterogeneous cellular networks
The topic of heterogeneous cellular networks has gained momentum in industry and the research community, attracting the attention of standardization bodies such as 3GPP LTE and IEEE 802.16j, whose objectives are looking into increasing the capacity and coverage of the cellular networks.
