We propose a modification of the widely known Benjamin-Johnson-Hui (BJH) cellular automaton model for single-lane traffic simulation. In particular, our model includes a ‘slow-to-stop’ rule that exhibits more realistic microscopic driver behaviour than the BJH model. We present some statistics related to fuel economy and pollution generation and show that our model differs greatly in these meas...

Nitrogen adsorption experiments have been extensively applied to shale pore structure research and evaluation. The can be quantitatively characterized in accordance with the nitrogen adsorption–desorption isotherm using various calculation models, whereas results obtained different models more effectively indicate characteristics of remains unclear. Further, there has not any unified process op...

We combine high-resolution isotherms measurements and light scattering technics to study over a broad temperature range collective effects during the condensation and evaporation of helium from Vycor, a prototypic disordered porous material. For evaporation, our results provide the first direct evidence for a crossover from a percolation collective mechanism at low temperature to a local cavita...

Statistical geometry is employed for a quantitative description of deviations from regular octahedrality of water around monovalent ions and from regular tetrahedrality of solvent water around water molecules. For these deviations a new criterion is presented by taking into account octahedral and tetrahedral spatial symmetry groups. A geometrical definition of structure making and structure bre...
