In a recent paper, Martens et al. introduced a specification mechanism for XML tree languages, based on rules of the form r s, where r, s are regular expressions. Sets of such ru...
Abstract. Learnability is a vital property of formal grammars: representation classes should be defined in such a way that they are learnable. One way to build learnable represent...
Low-connectivity and full-coverage three dimensional Wireless Sensor Networks (WSNs) have many real-world applications. By low connectivity, we mean there are at least k disjoint ...

We consider a restricted variant of the hairpin completion called bounded hairpin completion. The hairpin completion is a formal operation inspired from biochemistry. Applied to a ...
