Saving internal program data for further use is one of the most useful ideas in programming. Developing general features to provide such data saving/restoring is a very active research area. There are two application areas for such features we believe to b ...
The original TCV control system was designed in the late 1980s to be inherently network based in that all control operations were performed from X-windows terminals and the control computers were networked. Using VMS-VAX technology, the acquisition system ...
This document describes an implementation of recoverable objects that can be accessed concurrently. After a brief description of the possible uses of recoverable objects and after reviewing some of the new features of Ada 95 used in the implementation, the ...
The purpose of the paper is to present our approach for specifying system behavior. Our approach is based on operation schemas and a system interface protocol (SIP). Operation schemas describe the functionality of system operations by pre- and post-conditi ...
One of the fundamental differences between a centralized system and a distributed one is the notion of partial failures. The ability to efficiently and accurately detect failures is a key element underlying reliable distributed computing. In current distri ...
Dynamic power management (DPM) is a design methodology for dynamically reconfiguring systems to provide the requested services and performance levels with a minimum number of active components or a minimum load on such components. DPM encompasses a set of ...

There is a wide consensus that an object explicitly embodies an abstraction, but the exact meaning of this statement is not necessarily well understood. This paper argues that the abstraction embodied by an object (or a component) implementation is nothing ...
The article presents the concepts and the tools involved in the interactive design of artistic screens. The screen elements are derived from a small set of analytical contours provided by the screen designer. We present the requirements that these contours ...
We present GJ, a design that extends the Java programming language with generic types and methods. These are both explained and implemented by translation into the unextended language. The translation closely mimics the way generics are emulated by program ...
We have designed a series of computer sessions build around ImageJ (a public-domain software for image analysis), as a practical complement to a two-semester course in image processing. The students are challenged with simple practical imaging problems as ...
