Product Description

Ada is the only ISO-standard, object-oriented, concurrent, real-time programming language. It is intended for use in large, long-lived applications where reliability and efficiency are essential, particularly real-time and embedded systems. In this book, Alan Burns and Andy Wellings give a thorough, self-contained account of how the Ada tasking model can be used to construct a wide range of concurrent and real-time systems. This is the only book that focuses on an in-depth discussion of the Ada tasking model. Following on from the authors' earlier title Concurrency in Ada, this book brings the discussion up to date to include the new Ada 2005 language and the recent advances in real-time programming techniques. It will be of value to software professionals and advanced students of programming alike: indeed every Ada programmer will find it essential reading and a primary reference work that will sit alongside the language reference manual.

Concurrent and Real-Time Programming in Ada Review

Fully harnessing multi-core processors requires concurrent programming, yet most mainstream languages have little support or do so with poor portability. Well-written concurrent Ada programs can be extremely portable and support multi-core and multiple processors automatically. This book explores, in-depth, the concurrent programming ("tasking") part of the Ada language. The authors then show how the concurrent programming facilities of Ada are augmented by the language to support real-time programming. These standard real-time facilities are state-of-the-art, extending, for example, beyond the POSIX real-time facilities in their expressive power.

The book first establishes the necessary foundation for understanding concurrent programming by explaining the possible problems (e.g., deadlocks and race conditions) and highlighting some of the mechanisms traditionally used in concurrent programming, such as semaphores and message-passing.

The tasking part of Ada is then covered in full detail, necessarily including interactions with some other parts of the language, such as exceptions, but also including interactions with the Ada object-oriented language facilities. The implementations of a number of reusable concurrency abstractions serve to illustrate the use of the tasking features.

The authors next lay another foundation, this time for scheduling in real-time systems, and show how Ada directly supports the common approaches. Both fixed-priority and dynamic-priority dispatching are supported by Ada and these are covered in detail. Ada 2005 also defines a number of time-related abstractions, such as a monotonic clock and timing events, and these are also covered completely. As in the concurrent programming part of the book, a number of reusable abstractions are implemented; in this section they illustrate the real-time language facilities. A discussion of the popular Ravenscar Profile, adopted by some other languages, is included.

No language is perfect and Ada is no exception. The tasking part of Ada 83 was particularly controversial in the domain of real-time systems. Ada 95 addressed many of these issues and added some new ones. Ada 2005 does the same. These issues are not ignored in the book.

I own 46 books on Ada (not counting older editions of some of them), gathered over 27 years of applying the language. Some are excellent and some not, but this one is highly prized. I highly recommend it to professionals and students alike.

Customer survey studies deals with customers, consumers and user satisfaction from a product or service. In practice, many of the customer surveys conducted by business and industry are analyzed in a very simple way, without using models or statistical methods. Typical reports include descriptive statistics and basic graphical displays. As demonstrated in this book, integrating such basic analysis with more advanced tools, provides insights on non-obvious patterns and important relationships between the survey variables. This knowledge can significantly affect the conclusions derived from a survey.

Key features:

• Provides an integrated, case-studies based approach to analysing customer survey data.

• Presents a general introduction to customer surveys, within an organization ��s business cycle.
• Contains classical techniques with modern and non standard tools.
• Focuses on probabilistic techniques from the area of statistics/data analysis and covers all major recent developments.
• Accompanied by a supporting website containing datasets and R scripts.

Customer survey specialists, quality managers and market researchers will benefit from this book as well as specialists in marketing, data mining and business intelligence fields.

Modern Analysis of Customer Surveys: with Applications using R (Statistics in Practice) Review

I would be surprised if the book found an audience among practitioners. To me, it looks like a collection of academic papers, which, when they apply the various (mostly quite established) statistical methods to a standard benchmark dataset - typically, referring to R packages and other statistical software products that can be used for the task - do not seem to yield much novel insight about the data, leaving one with the question "So what did we gain by using these techniques?" I would put "Modern analysis of customer surveys" in the category of books whose primary beneficiaries are their authors.

Product Description

This book presents fundmentals of orbit determination--from weighted least squares approaches (Gauss) to today's high-speed computer algorithms that provide accuracy within a few centimeters. Numerous examples and problems are provided to enhance readers' understanding of the material.

Statistical Orbit Determination Review

I am a graduate student who has been trying to learn the fundamentals of Kalman filtering and estimation, and I never truly understood it until reading this book. I had previously been reading more mathematical based texts on the subject, but this book applies it to a real problem that in its simplest case can be easily visualized. I recommend this book for anyone looking for a concrete example of Kalman filtering and estimation.
The author spends a chapter discussing orbital mechanics, however, if you don't know anything about satellite orbits, there is enough information on the web (especially Wikipedia) to help you understand the variables and visualize the problem.

Valve and Transistor Audio Amplifiers Review

Very clearly written survey of the art of audio amplifier design over the last 50 years. Covers early tube amps, including classic McIntosh, Quad, Williamson, Ultralinear examples as well as OTL designs. Superb review of evolution of transistor amps from early efforts evolved from tube designs, 60s quasi-complementary designs, 70s differential amps with full complementary output, 80s MOSFET applications. Many examples dissected, and plenty of theory but not a cookbook for making amps. Does overlap some of his earlier books, so if you have them you may not find a lot of new content. Overall, best current survey on this topic around, clearly written by an expert, a pleasure to read cover to cover if you are fascinated by audio amplifier design.
