Overturning cars, flying missiles, and airplanes speeding across the screen – on modern computers, 3D objects can be calculated in a flash. However, many surfaces still look unnatural. Whether it is skin, stone or wax – on the computer screen, all materials look alike, as if the objects had all been cut out of the same kind of opaque material. This is about to change: TU Wien (Vienna), the Uni...

A mathematical algorithm jointly developed by EURAC and the University of Bolzano (unibz) now permits exceptionally rapid recognition of regular DNA sequences. The previous time of 20 days is reduced to just 5 hours under the new method. Its efficiency and methodological rigour has now led to the algorithm's incorporation in the world's most widely-used DNA-analysis software. This momentous scient...

If A is a decider (e.g, DFA)  or generator (e.g., CFG) then L(A) is the language  that it decides or generates. The following are well known: L(DFA) = L(NDFA) ⊂ L(DPDA) ⊂ L(PDA) ⊂ L(CSL). We are concerned with the  size of these devices. For a DFA and NDFA the size is the number of states, for a DPDA, PDA the size is the sum of the stack alphabet and the number of states, and...
