The widespread use of embedded controllers in dependability-relevant products requires a radical increase both in the productivity and in the quality of the overall design process, thus necessitating the automation and the integration of the functional and diagnostics design processes. Recently, the most e ective system design methodology is hardware-software codesign, supporting a uni ed model...

§0. Introduction This paper deals with the dynamics of polynomial diffeomorphisms f : C → C. To exclude trivial cases we make the standing assumption that the dynamical degree d = d(f) is greater than one (see Section 1 for a definition). It is often quite useful in dynamics to focus attention on invariant objects. A natural invariant set to consider is K = Kf , the set of points with bounded o...

In this study, a discrete fracture network model (DFN) and groundwater flow simulation were applied to fractured aquifer of an open-pit mine. Conditional the systems was developed quantify evaluate uncertainty geological structures predict possible hydrogeological risks associated with these uncertainties. The method used based on statistical characterization spatial distribution scenarios leng...

[1] While permeability scaling of fractured media has been so far studied independently at the fractureand networkscales, we propose a numerical analysis of the combined effect of fracture-scale heterogeneities and the network-scale topology. The analysis is based on 2 10 discrete fracture network (DFNs) simulations performed with highly robust numerical methods. Fracture local apertures are di...

Nowadays, numerical modelings play a key role in analyzing hydraulic problems in fractured rock media. The discrete fracture network model is one of the most used numerical models to simulate the geometrical structure of a rock-mass. In such media, discontinuities are considered as discrete paths for fluid flow through the rock-mass while its matrix is assumed impermeable. There are two main pa...

A modelling study is performed to assess the evolution of acid mine drainage (AMD) in fractured subsurface environments using two simulation methods: the equivalent porous medium (EPM) and the discrete-fracture network (DFN) approach. The 2D simulations are conducted using the numerical flow and reactive transport model POLYMIN (Molson et al. 2005) based on a mixed silicate-carbonate host rock ...

This paper reviews the heat transfer model for geothermal reservoirs, fracture network in and numerical of hydraulic fracturing. The first section models, which contain single-porosity model, dual-porosity multi-porosity model; meanwhile mathematical equations porosity are summarized. Then, this introduces reservoirs method computational transfer. In second section, on basis conventional theory...
