Numerical simulations of microscopic transport processes in porous electrodes lithium-ion batteries demonstrate the presence spatially localized fluctuations physical quantities on microstructure scale. They can influence macroscopic battery characteristics (for example, degradation rates). These cannot be captured a straightforward manner by widely used electrode theory Doyle, Fuller, and Newm...

A numerical characterization of a fractured rock mass and its mechanical behavior using discontinuum approach was carried out utilizing lattice-spring-based synthetic (LS-SRM) models. First, LS-SRM models on laboratory scale were created to reproduce standard tests Triassic sandstone samples from quarry in Germany. Subsequently, the intact properties upscaled an element volume representative fo...

We consider flows in fractured media, described by Discrete Fracture Network (DFN) models. We perform an Uncertainty Quantification analysis, assuming the fractures’ transmissivity coefficients to be random variables. Two probability distributions (log-uniform and log-normal) are used within different laws that express the coefficients in terms of a family of independent stochastic variables; t...

The equivalent pipe network (EPN) model is an effective way to fluid flow in large-scale fractured rock masses with a complex fracture due its straightforwardness and computational efficiency. This study presents the EPN for characterizing through three-dimensional networks using Monte-Carlo method. extracted from original discrete (DFN) used simulate processes. validity of proposed modeling ap...

A honeynet is a special prepared network which is not used in normal business. It is a kind of playground to watch and learn the tactics of crackers. The only purpose of a honeynet is to be probed, attacked or compromised. During the operation other systems may not be harmed by an attack originated within the honeynet. In this paper the design, realization and operation of a honeynet built with...
