Digital media are revolutionising design, both as a tool in design practice and as a way of thinking about design products, processes and systems.
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

This practical guide explains the use of randomization tests and provides example designs and macros for implementation in IBM SPSS and Excel. It reviews the theory and practice of single-case and small-n designs so readers can draw valid causal inferences from small-scale clinical studies. The macros and example data are provided on the book's website so that users can run analyses of the text data as well as data from their own studies.
The new edition features:
The book opens with an overview of single case and small n designs -- why they are needed and how they differ from descriptive case studies. Chapter 2 focuses on the basic concepts of randoization tests. Next how to choose and implement a randomization design is reviewed including material on how to perform the randomizations, how to select the number of observations, and how to record the data. Chapter 5 focuses on how to analyze the data including how to use the macros and understand the results. Chapter 6 shows how randomization tests fit into the body of statistical inference. Chapter 7 discusses size and power. The book concludes with a demonstration of how to edit or modify the macros or use parts of them to write your own.
Ideal as a text for courses on single-case, small n design, and/or randomization tests taught at the graduate level in psychology (especially clinical, counseling, educational, and school), education, human development, nursing, and other social and health sciences, this inexpensive book also serves as a supplement in statistics or research methods courses. Practitioners and researchers with an applied clinical focus also appreciate this book's accessible approach. An introduction to basic statistics, SPSS, and Excel is assumed.
The author, Mr. Curtis, in this volume, has undertaken the task of rescuing Mr. Webster's name from the obloquy which for a quarter of a century has been heaped upon it for his alleged desertion of the antislavery cause in 1850. The charge made against him was that, in the support of the "compromise measures" of that year, he sacrificed the interests of liberty, and did so with a base and selfish motive-that of securing the presidency for himself by the aid of Southern votes. The accusation, therefore, divides itself into two parts, and as to the latter half of it Mr. Curtis has comparatively easy work. He shows that there is not a particle of evidence of its truth, except the well-known desire of Mr. Webster for the presidency; but if such evidence as this is to be admitted in the case of public men, then all active support by them of measures about which there is a difference of opinion on the eve of important elections, they being candidates, must be considered evidence of interested motives. In the case of a man of such eminence as Mr. Webster it is at least fair to assume-in the absence of positive evidence to the contrary- that his view of public questions is dictated by a desire for the general good rather than the petty pursuit of personal ends. Mistaken as his ideas on the subject of the extension of slavery may have been, we have little doubt that they were honest ideas. Indeed, they were the views generally taken by the profession of which he was at the time the most distinguished leader; and it would not be difficult, had we space at our command, to justify from a professional point of view the bias of mind which led almost all the eminent lawyers of that time to distrust the Antislavery party; to regard it, equally with that of States rights, as a party of disunion, and to hope-even against hope-that some modus vivendi might be found for the Union on terms of toleration for slavery. They saw clearly that the alternative was a bloody war, and possibly a perpetual dissolution of the political bond which was the foundation of the prosperity of the country. They may certainly be excused for not having seen that the war, with all its risks, was inevitable.
