Discute o graffiti como patrimônio cultural e propõe que este possa ser preservado para as futuras gerações. Reconhece-se aspecto paradoxal obras do tipo inspiram em relação à proposta de sua institucionalização salvaguarda, posto princípio efeméride carrega si. Questiona-se: é caracterizado material ou imaterial? Como objetivo geral, propôs-se compreender conceitos caracterizem cultural, passí...

We present four empirical measures of the immediate usability of Graffiti, a character recognizer for pen-based computers. Since speed is fully controlled by the user, we measured the accuracy attainable after minimal exposure. The first measure, 79%, is the inherent accuracy, or the extent to which Graffiti strokes match letters in the Roman alphabet. The other three measures were obtained in ...

We study the well-known sociological phenomenon of gang aggregation and territory formation through an interacting agent system defined on a lattice. We introduce a two-gang Hamiltonian model where agents have red or blue affiliation but are otherwise indistinguishable. In this model, all interactions are indirect and occur only via graffiti markings, onsite as well as on nearest neighbor locat...

Since ancient times travellers and tourists were carving or writing their names and messages on historic landmarks. This behaviour has prevailed to this day as tourists try to leave their marks at places they visit. Such behaviour, today often seen as vandalism, is particularly problematic since the society tries to preserve historic landmarks while graffiti often leave indelible markings. One ...

My research involves finding bounds of graph theoretic invariants, in particular the independence number of a graph; constructing algorithms for calculating values of these invariants; investigating the structure of independent sets of vertices in graphs; and identifying and programming successful heuristics for automating conjecture-making. of these conjectures have involved the independence n...
