Resistance of two-dimensional soap froth
Cheung, K.M.; Tam, W.Y.; Szeto, K.Y. - In: Physica A: Statistical Mechanics and its Applications 281 (2000) 1, pp. 413-419
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...

Survivors in the two-dimensional Potts model: zero-temperature dynamics for Q = ∞
Hennecke, Michael - In: Physica A: Statistical Mechanics and its Applications 246 (1997) 3, pp. 519-528
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)...

Survivors in the two-dimensional Potts model: zero-temperature dynamics for finite Q
Hennecke, Michael - In: Physica A: Statistical Mechanics and its Applications 252 (1998) 1, pp. 173-177
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,...

Scaling the Costs of 404 Testing to Fit the Needs of Small Public Companies
Hallarin, Daniel - 2008
In July of 2002, the Sarbanes-Oxley Act was passed by Congress, including section 404 which requires the auditors to test and opine on the company's internal controls. Since that time there has been much debate about whether the intended benefits of increased investor confidence and financial...
