We present a new model of hypertext that represents both the relationships that tie individual pieces of information together into the hypertext (i.e., the adjacencies) and also the browsing semantics to be associated...

Two complementary methods are proposed for characterizing the spatial structure of digitized technical documents and labelling various logical components without using optical character recognition. The top-down metho...

An active data model is one that not only stores data, but also acts upon changes to the data in ways that reflect application domain semantics. This paper introduces an active object-oriented model based on increment...

UNIX Emacs is well-known and widely used as a text editor that has been extended in a remarkable number of directions, not always wisely. Because it is programmable in a powerful yet simple programming language, Emacs...

To achieve the maximum performance from bitmap displays, the screen must be used not just as an output device, but as a data structure that may cache computed images. In an interactive text or picture editor, that may...

Our society is depending more and more on the reliability of embedded (real-time) computer systems even in every-day life. Considering the complexity of the real world, this might become a severe threat. Real-time programming is a discipline important not only in process control and data acquisition systems, but also in fields like communication, office automation, interactive databases, interactivegraphics and operating systems development. General concepts of concurrent programming and constructs for process-synchronization are discussed in detail. Tasking and synchronization concepts, methods of process communication, interrupt- and timeout handling in systems based on semaphores, signals, conditional critical regions or on real-time languages like Concurrent PASCAL, MODULA, CHILL and ADA are explained and compared with each other and with respect to their potential to quality and safety.

interactivegraphics displays can provide the operator with powerful tools to view a batch process. An inherent property of the batch process is that 'normal' is always changing. This offers a considerable challenge to the display designer to display abnormal by exception. Several new techniques are presented that take advantage of powerful display building tools.
