Influence depth of highway subgrade under heavy vehicle loads based on a theoretical model

Frontiers in Built Environment
A three-dimensional dynamic model of vehicle-road-unsaturated subgrade coupling is established. The semi-analytical and numerical solutions of three-dimensional dynamic response of highway subgrade under vehicle load are presented for the first time ...

Voronoi Cell Patterns: theoretical model and applications

, 2011
We use a simple fragmentation model to describe the statistical behavior of the Voronoi cell patterns generated by a set of points in 1D and in 2D. In particular, we are interested in the distribution of sizes of these Voronoi cells.

Theoretical Model for the Semimetal Yb_4As_3

, 1995
We present a model which can explain semiquantitatively a number of the unusual properties of \mbox{Yb$_4$As$_3$}. The structural phase transition at $T_{\text{c}}\simeq300\,\mbox{K}$ is described by a band Jahn-Teller effect of correlated electrons and ...
