We study finitely generated groups whose word problems are accepted by counter automata. We show that a group has word problem accepted by a blind n-counter automaton in the sense of Greibach if and only if it is virtually free abelian of rank n; this result, which answers a question of Gilman, is in a very precise sense an abelian analogue of the Muller-Schupp theorem. More generally, if G is ...

The notion of assumption plays an important role in the literature on critical thinking. However, the critical imperative of revealing one’s assumptions forces one either to follow some predefined scheme in which they are defined—in which case it restricts thinking and runs counter to the critical ideal—or to recognise that one cannot know those assumptions— in which case it is impossible. In t...

Anionic reactive dyes used to dye nylon suffer from failures due to the poor efficiency caused by low degree of exhaustion and fixation. From the previous work , the dyeing efficiency of Procion Rubine XL on modified nylon was particularly week and hence offers the widest scope for an in depth investigation in to variables that effect the dyeing process. The variables dyeing studies for this pr...

Dye-sensitized solar cells present promising low-cost alternatives to the conventional Silicon (Si)-based solar cells. The counter electrode  generally consists of Pt deposited onto FTO plate. Since Pt is rare and expensive metal, nanostructured carbonaceous materials have been widely investigated as a promising alternative to replace it. Carbon nanotubes  have shown significant properties such...
