The resistance of two-dimensional soap froth cellular network has been measured experimentally. The resistance increases nonlinearly after a transient period. An iterative map using the substitution of simple resistor network has been used to describe the experimental observation. Calculation is...

The dynamics of the fraction of never flipped spins F(t) and the average domain area A(t) of the two-dimensional, infinite-Q Potts model are investigated by zero-temperature Monte Carlo simulations. It is shown that the exponents α of algebraic growth of A(t) and Θ of algebraic decay of F(t)...

The Q-dependence of the dynamics of the fraction of never flipped spins F(t) and the average domain area A(t) of the triangular Q-state Potts model are investigated by zero-temperature Monte Carlo simulations. Extending a recent study [Hennecke, Physica A 246 (1997) 519] for Q=∞ to finite Q,...

Academic Entrepreneurship in the last three decades has risen to greater heights. There are various reasons too. Indian's education sector has been undergoing sea changes in these decades. Every state has been opening up and there has been a plethora of institutions established. In the process,...
