We studied existing systems, first in a general context, by making the distinction between physical and logical structure recognition systems. Then, we focused on methods specific for complex layout documents and on methods having a learning aptitude. Since there do not seem to exist learning systems which are able to recognise...

During senescence, chlorophyll of higher plants is degraded into linear tetrapyrrolic catabolites. Their in vitro oxidation with chromic acid furnishes the constituting pyrrolic moieties as maleimides fragments. The substitution patterns of the isolated maleimides are related to the catabolites structures. All maleimides bear the characteristic methyl group of the former chlorophyll as well as a...

Ad hoc wireless multi-hop networks (AHWMNs) are communication networks that consist entirely of wireless nodes, placed together in an ad hoc manner, i.e. with minimal prior planning. All nodes have routing capabilities, and forward data packets for other nodes in multi-hop fashion. Nodes can enter or leave the network at any time, and may be mobile, so that the network topology continuously...
