For graphs G and H the Ramsey number r(G, W) is defined to be the least number p such that every 2-coloring (say green and red) of the edges of the complete graph KP contains either a subgraph G with all its edges green, or a subgraph M with all its edges red. The diagonal Ramsey numbers r(G, G) = r(G) for G = K,, are of particular interest. The values r(&) = 6, and r(&) = 18 are well known, bu...

Evolution von XML-Schemata auf konzeptioneller Ebene - Übersicht: Der CodeX-Ansatz zur Lösung des Gültigkeitsproblems

If new requirements arise models have to be adapted to them. Additionally, the instances based on these models have to be adapted as well otherwise they might not be valid anymore. The same applies to the XML schema as a model and widely accepted description for XML documents. One solution for solving the occurring validity problem is the here described XML schema evolution. On the basis of a c...

The first medical visitors were usually naval surgeons or served on board whaling ships. The major influx of doctors occurred at the behest of the New Zealand Company between 1840 and 1848, although Christian mis...
