Finding Optimal Targets for Change Agents: A Computer Simulation of Innovation Diffusion

Maienhofer, Dirk; Finholt, Thomas A. - 2002

We introduce a diffusion of innovation model based on a network threshold approach. Realistic network and threshold data were gathered regarding the diffusion of new software tools within part of a large organization. Novel model features are a second threshold for innovation rejection and a...

Effects of discretization on viscosity in the necklace model

Mártin, D.A.; Aldao, C.M. - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 4, pp. 723-730

The consequences of discretization on the resulting viscosity for the necklace model are analyzed to find out the … perform a random walk are analyzed. Knowing of these influences on the viscosity, we finally address the effect of length … fluctuations. It is shown that fluctuations can have unexpected effects that lead to larger or smaller values of viscosity. The …

Excluded volume effect on entropy and clustering behaviors in supercooled liquids and glasses

Rah, Kyunil - In: Physica A: Statistical Mechanics and its Applications 389 (2010) 1, pp. 27-39

We study the significant entropy changes in supercooling and glass transition by developing a two (H and L) state cluster model, where the H-state represents the clusters with the coordination number z being larger than the reference size zR and the L-state those with zzR, respectively. We...
