Choice Outstanding Academic Title, 2009. Hundreds of programming languages are in use today--scripting languages for Internet commerce, user interface programming tools, spreadsheet macros, page format specification languages, and many others. Designing a programming language is a metaprogramming activity that bears certain similarities to programming in a regular language, with clarity and simplicity even more important than in ordinary programming. This comprehensive text uses a simple and concise framework to teach key ideas in programming language design and implementation. The book's unique approach is based on a family of syntactically simple pedagogical languages that allow students to explore programming language concepts systematically. It takes as its premise and starting point the idea that when language behaviors become incredibly complex, the description of the behaviors must be incredibly simple. The book presents a set of tools (a mathematical metalanguage, abstract syntax, operational and denotational semantics) and uses it to explore a comprehensive set of programming language design dimensions, including dynamic semantics (naming, state, control, data), static semantics (types, type reconstruction, polymporphism, effects), and pragmatics (compilation, garbage collection). The many examples and exercises offer students opportunities to apply the foundational ideas explained in the text. Specialized topics and code that implements many of the algorithms and compilation methods in the book can be found on the book's Web site, along with such additional material as a section on concurrency and proofs of the theorems in the text. The book is suitable as a text for an introductory graduate or advanced undergraduate programming languages course; it can also serve as a reference for researchers and practitioners.
Through this book's unique model comparison approach, students and researchers are introduced to a set of fundamental principles for analyzing data. After seeing how these principles can be applied in simple designs, students are shown how these same principles also apply in more complicated designs.
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

A short book in the series "Web Security Topics", by the well-known authors Nigel and Jenny Chapman. Written for Web developers who act as part-time sysadmins, this handy guide deals with a crucial aspect of Web security - securing the system on which your Web applications are hosted. It provides a clear, easy-to-understand introduction to securing a Web server host running a Unix-like operating system such as Ubuntu Server. The book offers a commonsense, practical approach to everyday security for busy developers who have to take responsibility for setting up and securing Web servers for small businesses and non-profit organizations which do not have critical security requirements. Based on first-hand practical experience combined with extensive computing knowledge, this book explains the important principles and processes which every developer administering a server host needs to understand. Full of down-to-earth advice, it describes how to avoid the main pitfalls and security risks when administering a server host - and explains why each step must be taken. Topics covered include the available methods for remotely administering a server and transferring files to it, systems of permissions based on user accounts, how to restrict users and processes to minimize security risks, how to prevent unwanted connections by eliminating inessential servers and setting up a firewall, and how to recover from break-ins to the server if the worst should happen. Clear key points provide useful summaries at the end of each section, and a valuable 14-page glossary of technical terms is included. FREE PDF OFFER: a mail-in form at the back of the book enables every purchaser to claim a free PDF copy from the publisher. This guide is not intended for developers administering Windows-based servers.
Considerably expanded and updated, the second edition of this bestselling reference and textbook is updated with current wireless systems with sections on 4G and the technologies behind 5G cellular communications. This book includes 10 real world case studies of leading edge designs, taking readers through the design process and the many pragmatic designs that must be made during the process. It includes extensive end-of-chapter exercises ranging from less challenging testing to involved, open-ended design exercises.
