An important aspect of teaching a course in compiler writing is to illustrate the key theoretical concepts normally taught in such a course. A frequently used strategy for achieving this goal is to have a student design a simple programming language and implement a compiler for this language. Many texts in compiler writing do not,...

Programmable logic controllers (PLCs) continue to evolve as new technologies are added to their capabilities. The PLC started out as a replacement for hardwired relay control systems. Gradually, various math and logic manipulation functions were added. Today PLCs are the controller of choice for the vast majority of automated...

The journal Computing has established a series of supplement volumes the fourth of which appears this year. Its purpose is to provide a coherent presentation of a new topic in a single volume. The previous subjects were Computer Arithmetic 1977, Fundamentals of Numerical Computation 1980, and Parallel Processes and Related Automata...

The decade of the 80's saw the dramatic expansion of high performance computer graphics into domains previously able only to irt with the technology. Among the most dramatic has been the incorporation of real-time interactive manipulation and display for human gures. Though actively pur- sued by several research groups, the...

The roots of the project which culminates with the writing of this book can be traced to the work on logic synthesis started in 1979 at the IBM Watson Research Center and at University of California, Berkeley. During the preliminary phases of these projects, the impor tance of logic minimization for the synthesis of area and...

"The security of information systems has not improved at a rate consistent with the growth and sophistication of the attacks being made against them. To address this problem, we must improve the underlying strategies and techniques used to create our systems. Specifically, we must build security in from the start, rather than append...

The history of software development paradigms suggests that a new paradigm often has its genesis in programming languages and then moves up to design and analysis (e.g., structured programming preceded structured design and analysis, and objectoriented programming predated object-oriented design and modeling). This same pattern can...

In September 1994 the seventh International Conference on Intelligent Robots and Systems- IROS '94-- was held in Neubiberg, a suburb of Munich, Germany, on the premises of the German Armed Forces University Munich. Of the 300 papers presented during the conference I have selected 48 ones which, in my subjective opinion, are...
