    The difficulties of writing large programs are discussed briefly, showing how they led to the concept of software engineering. The development of the Ada language is described. The principal concepts of software engineering, namely, information hiding, encapsulation, separation of concerns, abstraction, verification, and reusability, are defined, and their expression in Ada is shown.<> View full abstract»

    The development of a computer architecture that will provide the basis for integrated avionic systems is examined. This new architecture is intended to provide the backbone for avionics for aircraft being designed in the 1990s; the US Air Force program by which this architecture is being defined and specified is called Pave Pillar. The processor, operating system, software, and data buses are desc... View full abstract»

    The applications of digital data compression and the major components of compression systems are described. Data modeling is discussed, and the role of entropy and data statistics is examined. Gray-scale image modeling is used to illustrate some of these mechanisms. The coding mechanisms are examined, and prefix codes are explained. Arithmetic coding is considered.<> View full abstract»
