The probability distribution of isomeric conformations in poly(dimethylsi1oxane) has been investigated both by conformational energy considerations and by molecular dynamics simulations. A comparatively smooth distribution of isomeric states is obtained from both approaches. The molecular dynamics trajectory of a simulated dimethylsiloxane oligomer of eight units is used as a reliable and reali...

Abstract The description of gel swelling by Flory and Rehner using the original Flory–Huggins interaction parameter for polymer–solvent cannot be applied to most smart microgels. Here, we compare descriptions curves such microgels series expansions $$\chi$$ ? with results Hill-like equation . We study N -isop...

A new two-parameter lifetime distribution is proposed and numerically studied. The model has a flflexible failure rate shapes such as “monotonically increasing” , decreasing” “bathtub” “constant” “upside down” “J-shape” . Various of its statistical properties are derived. numerical analysis skewness kurtosis presented. Many bivariate multivariate extensions also presented via Farlie Gumbel Morg...

We investigate chaotic, memory, and cooling rate effects in the three-dimensional Edwards-Anderson model by doing thermoremanent ~TRM! and ac susceptibility numerical experiments and making a detailed comparison with laboratory experiments on spin glasses. In contrast to the experiments, the Edwards-Anderson model does not show any trace of reinitialization processes in temperature change exper...

Anderson localization of classical waves in random arrays of dielectric cylinders is numerically investigated as a function of the distribution of their diameters. We show that using polydispersed resonant scatterers increases the localization length, while using identical resonant scatterers fosters Anderson localization. We discuss this collective process and link it to the effect of proximit...
