The paper describes research projects in Germany which develop and use multimedia applications. An overview is given about some of the major players’ (TUB, DeTeBerkom, DFN, FhG, GMD) programs (BERKOM, POLIKOM, RTBs) and applications (JVTOS, MMC, MMM, MMT, VoD).

Let φ (z) be a fixed analytic and univalent function of the form φ(z) = z + ∑∞ k=2 ckz k and Hφ (ck, δ) be the subclass consisting of analytic and univalent functions f of the form f(z) = z + ∑∞ k=2 akz k which satisfy the inequality ∑∞ k=2 ck |ak| ≤ δ. In this paper, we determine the sharp lower bounds for Re { Dpf(z) Dfn(z) } and Re { Dfn(z) Dpf(z) } , where fn(z) = z + ∑n k=2 akz k be the se...

This paper introduces a comprehensive C++ software package, HatchFrac, for stochastic modeling of fracture networks in two and three dimensions. The inverse cumulative distribution function (CDF) acceptance–rejection methods are applied to generate random variables from the distributions commonly used discrete network (DFN) modeling. multilayer perceptron (MLP) machine learning approach, combin...

Fluid flow in jointed rock mass with impermeable matrix is often controlled by joint properties, including aperture, orientation, spacing, persistence and etc. On the other hand, since the rock mass is made of heterogeneous and anisotropic natural materials, geometric properties of joints may have dispersed values. One of the most powerful methods for simulation of stochastic nature of geometri...

Abstract In several applications concerning underground flow simulations in fractured media, the rock matrix is modeled by means of Discrete Fracture Network (DFN) model. The fractures are typically described through stochastic parameters sampled from known distributions. this framework, it worth considering application suitable complexity reduction techniques, also view possible uncertainty qu...

This paper summarises two approaches, Dual Flow Nets (DFN) and Object Petri Nets (OPN), and offers a translation mechanism between them. While the DFN model tackles the separation of control and data flow computing aspects, the OPN model has a more generalised structure. The aim of this paper is to show how the modelling based on control/data-flow analysis can benefit from an object-based Petri...

Under the auspices of the DECOVALEX II international project, the coupled hydromechanical responses, in the fractured volcanic rocks at Sellafield site, to a pump test and shaft sinking were studied. The aim of this paper is to describe the methodology for analysing the hydromechanical responses of a long-term pump test in borehole RCF3 drilled on the centreline of one of the proposed shafts. T...

Subsurface applications including geothermal, geological carbon sequestration, oil and gas, etc., typically involve maximizing either the extraction of energy or the storage of fluids. Characterizing the subsurface is extremely complex due to heterogeneity and anisotropy. Due to this complexity, there are uncertainties in the subsurface parameters, which need to be estimated from multiple diver...

A discussão sobre políticas de acessibilidade envolve várias possibilidades investigação e análise, quanto à chegada da pessoa com Deficiência Física Neuromotora/Paralisia Cerebral (DFN/PC) no ensino superior. Nesse contexto, o estudo tem como objetivo analisar acesso a permanência estudantes DFN/PC nesse nível ensino. metodologia contemplou pesquisa bibliográfica, por meio interpretação pressu...

A new method for simulating solute transport and geochemical interactions within fractured rock is presented. This will be an important capability assessing the safety of radioactive waste disposal facilities that are located crystalline bedrock. Specifically, discrete fracture network (DFN) module ConnectFlow groundwater flow software has been updated to: (i) simulate advection diffusion more ...
