The collection of papers published in this book was initially presented at the Workshop on Software Factories and Ada, held on Capri, May 26-30, 1986. The subject of the book is software development environments. Software development is treated from three viewpoints: methodologies, language issues and mechanisms. Of particular interest are the discussions of automation of the development process and the formalization of software development specifications. Several new methodologies are described, many of which are available on the commercial market. New is in particular the formalization of the design and development process. Interesting ideas are presented on planning the design process and on supporting project management by formal tools. The reader will find a variety of interesting methodologies and mechanisms that are operational. The book is suitable for readers interested in knowing in which direction programming environment research is moving.

(a) Design and construction. (1) Each facility or part of a facility constructed by, on behalf of, or for the use of a public entity shall be designed and constructed in such manner that the facility or part of the facility is readily accessible to and usable by individuals with disabilities, if the construction was commenced after January 26, 1992. (2) Exception for structural impracticability. (i) Full compliance with the requirements of this section is not required where a public entity can demonstrate that it is structurally impracticable to meet the requirements. Full compliance will be considered structurally impracticable only in those rare circumstances when the unique characteristics of terrain prevent the incorporation of accessibility features. (ii) If full compliance with this section would be structurally impracticable, compliance with this section is required to the extent that it is not structurally impracticable. In that case, any portion of the facility that can be made accessible shall be made accessible to the extent that it is not structurally impracticable. (iii) If providing accessibility in conformance with this section to individuals with certain disabilities (e.g., those who use wheelchairs) would be structurally impracticable, accessibility shall nonetheless be ensured to persons with other types of disabilities, (e.g., those who use crutches or who have sight, hearing, or mental impairments) in accordance with this section.

This book presents the rationale behind the design and development of the programming language Ada. The materials incorporating corrections to its original printing by the Ada Joint Program Office (AJPO), will be essential reading for all those currently using the language as well as those considering its adoption.

The arrival and popularity of multi-core processors has sparked a renewed interest in the development of parallel programs. Similarly, the availability of low-cost microprocessors and sensors has generated a great interest in embedded real-time programs. This book provides students and programmers whose backgrounds are in traditional sequential programming with the opportunity to expand their capabilities into parallel, embedded, real-time and distributed computing. It also addresses the theoretical foundation of real-time scheduling analysis, focusing on theory that is useful for actual applications. Written by award-winning educators at a level suitable for undergraduates and beginning graduate students, this book is the first truly entry-level textbook in the subject. Complete examples allow readers to understand the context in which a new concept is used, and enable them to build and run the examples, make changes, and observe the results.

Ada 95 is the first fully object-oriented programming language to be internationally standardized. John Barnes was a key member of the language's design team, and this is a new edition of his definitive text and reference for the Ada 95 language.

This book contains the proceedings of the 1989 Ada-Europe conference. These meetings constitute the most significant events in this field within Europe, and attract delegates from around the world. The theme of this year's conference is design methods; this is of major importance since both Ada compilers and the applications built with Ada are huge. Papers in this volume, which have all been carefully refereed, study the design methods within Ada, and how they may need to be augmented with additional methods and tools where necessary. They make informed and essential reading for all involved in the use of Ada in industry and research.
