A comprehensive approach to the air vehicle design process using the principles of systems engineering
Due to the high cost and the risks associated with development, complex aircraft systems have become a prime candidate for the adoption of systems engineering methodologies. This book presents the entire process of aircraft design based on a systems engineering approach from conceptual design phase, through to preliminary design phase and to detail design phase.
Presenting in one volume the methodologies behind aircraft design, this book covers the components and the issues affected by design procedures. The basic topics that are essential to the process, such as aerodynamics, flight stability and control,Â aero-structure, and aircraft performance are reviewed in various chapters where required.Â Based on these fundamentals and design requirements, the author explains the design process in a holistic manner to emphasise the integration of the individual components into the overall design. Throughout the book the various design options are considered and weighed against each other, to give readers a practical understanding of the process overall.Â
Readers with knowledge of the fundamental concepts of aerodynamics, propulsion, aero-structure, and flight dynamics will find this book ideal to progress towards the next stage in their understanding of the topic. Furthermore, the broad variety of design techniques covered ensures that readers have the freedom and flexibility to satisfy the design requirements when approaching real-world projects.
?Â Â Â Â Â Â Â Â Â Provides full coverage of the design aspects of an air vehicle including: aeronautical concepts, design techniques and design flowcharts
?Â Â Â Â Â Â Â Â Features end of chapter problems to reinforce the learning process as well as fully solved design examples at component level
?Â Â Â Â Â Â Â Â Â Includes fundamental explanations for aeronautical engineering students and practicing engineers
?Â Â Â Â Â Â Â Â Â Features a solutions manual to sample questions on the book?s companion website

With the proliferation of VHDL, the reference material also grew in the same order. Today there is good amount of scholarly literature including many books describing various aspects of VHDL. However, an in-depth review of these books reveals a different story. Many of them have emerged simply as an improved version of the manual. While some of them deal with the system design issues, they lack appropriate exemplifying to illustrate the concepts. Others give large number of examples, but lack the VLSI system design issues. In nutshell, the fact which gone unnoticed by most of the books, is the growth of the VLSI is not merely due to the language itself, but more due to the development of large number of third party tools useful from the FPGA or semicustom ASIC realization point of view. In the proposed book, the authors have synergized the VHDL programming with appropriate EDA tools so as to present a full proof system design to the readers. In this book along with the VHDL coding issues, the simulation and synthesis with the various tool sets enables the potential reader to visualize the final design. The VHDL design codes have been synthesized using different third party tools such as Xilinx Web pack Ver.11, Modelsim PE, Leonrado Spectrum and Synplify Pro. Mixed flow illustrated by using the above mentioned tools presents an insight to optimize the design with reference to the spatial, temporal and power metrics.
Surrogate models expedite the search for promising designs by standing in for expensive design evaluations or simulations. They provide a global model of some metric of a design (such as weight, aerodynamic drag, cost, etc.), which can then be optimized efficiently. <p> <p> <i>Engineering Design via Surrogate Modelling</i> is a self-contained guide to surrogate models and their use in engineering design. The fundamentals of building, selecting, validating, searching and refining a surrogate are presented in a manner accessible to novices in the field. Figures are used liberally to explain the key concepts and clearly show the differences between the various techniques, as well as to emphasize the intuitive nature of the conceptual and mathematical reasoning behind them. <p> More advanced and recent concepts are each presented in stand-alone chapters, allowing the reader to concentrate on material pertinent to their current design problem, and concepts are clearly demonstrated using simple design problems. This collection of advanced concepts (visualization, constraint handling, coping with noisy data, gradient-enhanced modelling, multi-fidelity analysis and multiple objectives) represents an invaluable reference manual for engineers and researchers active in the area. <p> <p> <i>Engineering Design via Surrogate Modelling</i> is complemented by a suite of Matlab codes, allowing the reader to apply all the techniques presented to their own design problems. By applying statistical modelling to engineering design, this book bridges the wide gap between the engineering and statistics communities. It will appeal to postgraduates and researchers across the academic engineering design community as well as practising design engineers. <p> <ul> <li>Provides an inclusive and practical guide to using surrogates in engineering design. <li>Presents the fundamentals of building, selecting, validating, searching and refining a surrogate model. <li>Guides the reader through the practical implementation of a surrogate-based design process using a set of case studies from real engineering design challenges. </ul> <p> <b>Accompanied by a companion website featuring Matlab software at</b> <b><u><a href="http://www.wiley.com/go/forrester">http://www.wiley.com/go/forrester</a></u></b>

At seven levels, from Starter to Advanced, this impressive selection of carefully graded readers offers exciting reading for every student's ability. Dan Combes is a former MI6 agent living peacefully in France. After being attacked by a former colleague, he realises his relationship with the British Secret Service has not yet finished. He believes the attack is linked to his roles in Berlin and Central America. But that was years ago so why do they want him dead now? Dan returns to England and confronts his difficult past - a web of lies and deceit that he knows must end. Paperback-only version. Also available with Audio CDs including complete text recordings from the book.
The book covers topics such as cell timing and power modeling; interconnect modeling and analysis, delay calculation, crosstalk, noise and the chip timing verification using static timing analysis. For each of these topics, the book provides a theoretical background as well as detailed examples to elaborate the concepts.
The static timing analysis topics covered start from verification of simple blocks useful for a beginner to this field. The topics then extend to complex nanometer designs with in-depth treatment of concepts such as modeling of on-chip variation, clock gating, half-cycle paths, as well as timing of source-synchronous interfaces such as DDR. The impact of crosstalk on timing and noise is covered as is the usage of hierarchical design methodology.
This book addresses CMOS logic gates, cell library, timing arcs, waveform slew, cell capacitance, timing modeling, interconnect parasitics and coupling, pre- and post-layout interconnect modeling, delay calculation, specification of timing constraints for analysis of internal paths as well as IO interfaces. Advanced modeling and analysis concepts such as controlled current source timing and noise models for nanometer technologies, power modeling including active and leakage power, crosstalk timing and crosstalk glitch calculation, verification of half-cycle and multi-cycle paths, false paths, synchronous interfaces are also covered.
