Lazy functional languages have non-strict semantics and are purely declarative, i.e. they support the notion of referential transparency and are devoid of side effects. Traditional debugging techniques are, however, n...

The safety of software is becoming increasingly important as computers pervade control systems on which human life depends. Whilst hardware has become significantly more reliable over the years, the same cannot be said of software. This has become more complex and methods to ensure its correctness have been slow in development. One approach is to mathematically verify software in such systems. This paper investigates the industrial use of these techniques, their advantages and disadvantages, and the introduction of standards and their recommendations concerning formal methods in this area. The cost of safety is also considered.
This paper considers a range of theoretical approaches to the understanding of organisations and the implications these views have for the design of computer supported cooperative work systems. Organisations have ofte...

An efficient backward execution algorithm in the AND/OR Process Model for parallel evaluation of logic programs is proposed. The efficiency of the algorithm is achieved by means of information acquired during execution of clauses. The algorithm is considered to be efficient in the sense that it issues fewer number of cancel messages and avoids unnecessary resetting operations. Furthermore, it performs independent redoing and resetting more concurrently than other related works.
A semantic file system is an information storage system that provides flexible associative access to the system's contents by automatically extracting attributes from files with file type specific transducers. Ass...
