Currently, there are basically two approaches to classification, one based on structural and one on positional changes occurring within the joint. Despite the increase in knowledge of pathologic changes occurring within the temporomandibular joint (TMJ), the disc still seems to be a central issue in nomenclature and classifications of TMJ disorders. Basic pathologies of the TMJ involve inflamma...

Buckling of cylindrical sandwich shells subject to axial compression is addressed for shells having foamed metal cores. Optimal face sheet thickness, core thickness and core density are obtained which minimize the weight of a geometrically perfect shell with a speci®ed load carrying capacity. Constraints imposed by wrinkling and yielding of the face sheets and yielding of the core are all consi...

The taxonomy (basic structural characteristics and relationships) of the simple graphs of small order is of fundamental importance in graph theory. This joint work with Peter Adams (Univ. Queensland, Australia) and James MacDougall (Univ. Newcastle, Australia) reports on the taxonomy of the 12,005,168 simple graphs of order 10. Topics discussed include their degree sequences, particularly multi...
