New book released in 2009. Almost all computer systems in general, and embedded systems in particular, are eventdriven, which means that they continuously wait for the occurrence of some external or internal event such as a time tick, an arrival of a data packet, a button press, or a mouse click. After recognizing the event, such systems react by performing the appropriate computation that may include manipulating the hardware or generating “soft” events that trigger other internal software components. (That’s why event-driven systems are alternatively called reactive systems.) Once the event handling is complete, the software goes back to waiting for the next event.

搜索了一下发现没有第二版的。This book is primarily concerned with the provision of good flying and handling qualities in conventional piloted aircraft, although the material is equally applicable to the uninhabited air vehicle (UAV). Consequently it is also very much concerned with the stability, control and dynamic characteristics which are fundamental to the determination of those qualities. Since flying and handling qualities are of critical importance to safety and to the piloting task it is essential that their origins are properly understood. Here then, the intention is to set out the basic principles of the subject at an introductory level and to illustrate the application of those principles by means of worked examples.

Data modeling and database design have undergone significant evolution in recent years. Today, the relational data model and the relational database system dominate business applications. The relational model has allowed the database designer to focus on the logical and physical characteristics of a database separately. In this book, we concentrate on techniques for database design with a very strong bias for relational database systems, using the ER (entity relationship) approach for conceptual modeling (solely a logical implementation).
