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,...

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...

The scaling of performance measures yields a consistent or dimensionless … alternative methods for scaling and amalgamation. Also, recognizing that project outcomes are not always known with certainty, the …

In this paper we investigate scaling properties of risky asset returns and make a strong case (1) against the need for …-range dependent. These scaling properties are well known, although commonly ignored for modeling convenience. However, much more can … be inferred from the scaling properties of the returns. It turns out that the empirical scaling functions are initially …
