Accurate classification of images is essential for the analysis of mammograms in computer aided diagnosis of breast cancer. We propose a new approach to classify mammogram images based on fractal features. Given a mammogram image, we first eliminate all the artifacts and extract the salient features such as Fractal Dimension (FD) and Fractal Signature (FS). These features provide good descripti...

One of the major challenges involved in digital preservation is to understand what the problem of preserving digital objects is in all of its diverse, idiosyncratic instantiations, rather than to look for uniform, technically feasible, economically sustainable, and standard-compliant solutions. We argue that by using a situated, descriptive approach to the investigation of actual environments w...

This paper illustrates an algorithm for finding a readonly memory (ROM) specification, optimal in the sense that it results in a minimum ROM bit dimension, starting with an instruction set description which employs acyclic directed graphs. The algorithm selects (by a tabular technique) a descriptive graph subset, shown to be sufficient; then it performs a heuristically guided search among possi...
