In this paper, we design linear time algorithms to recognize and determine topological invariants such as genus and homology groups in 3D. These invariants can be used to identify...
Taxonomies for a set of features occur in many real-world domains. An example is provided by paleontology, where the task is to determine the age of a fossil site on the basis of t...
One form of group support system that has received much attention from cross-disciplinary research is electronic brainstorming (EBS). While it is generally held that group cohesiv...
Decision making, whether by an individual or a group, can be substantially enhanced by a "systems thinking" approach. Because groups are often challenged to justify thei...
A k-orbit map is a map with k flag-orbits under the action of its automorphism group. We give a basic theory of k-orbit maps and classify them up to k 4. “Hurwitz-like” upper...
