This paper outlines the requirements and components for a proposed Document Analysis System, which assists a user in encoding printed documents for computer processing. Several critical functions have been investigated and the technical approaches are discussed. The first is the segmentation and classijication of digitized printed documents into regions of text and images. A nonlinear, run-leng...

BASED on vast experience watching the fruit of my hard work fall apart time and again, I feel highly qualified to discuss the manner in which systems break. In particular, the goal of this paper is to define and analyze systems which exhibit brittle behavior. This behavior is characterized by a sudden and steep decline in performance as system state changes as shown by point D along curve Ph in...

This may be hyperbole, but it does emphasize an inherent truth: the complex interdependency of different parts of the system. That is, events in geographically distant parts of the system may interact strongly and in unexpected ways. Power system analysis is concerned with under...
