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...

Discrete fracture network (DFN) is an effective means of describing the coupling heat flow in underground fractured rock mass. In this paper, improved DFN proposed by introducing correlation function trace length and aperture, which more consistent with real data. Next, based on model, influence roughness fluid transmission was evaluated, relationship between aperture joint coefficient (JRC) es...

Zusammenfassung Das DFN-Projekt QUASAR untersucht Quality-of-ServiceArchitekturen für das DFN G-WiN. In enger Kooperation mit anderen europäischen Forschungsnetzbetreibern wurde im Rahmen des IST Projektes SEQUIN hierzu ein Premium IP Dienst entwickelt, der im pan-europäischen Backbone GÉANT implementiert und in ersten Feldversuchen erprobt wurde. In diesem Beitrag werden die Grundzüge des Prem...

Zusammenfassung: Der Beitrag befasst sich mit einem möglichen Betriebsmodell für den Einsatz von VoIP im DFN-Umfeld. Im Rahmen eines Projekts der Partner T-Systems, Cisco, DFN-Verein und Universität Hannover/RRZN wird untersucht, wie ein von einem externen Dienstleister betriebener VoIP-Dienst – hier von TSystems angeboten und mit Komponenten von Cisco realisiert – umgesetzt werden kann. Neben ...

Anomaly traffic detecting using Netflow data is one of important problems in the field of network security. In this paper, we proposed an approach using MapReduce model, which was realized by means of the entropy observation and DFN (Distinct feature number) distribution deviations of traffic features under anomalies at small time scales. The MapReduce was used to deal with huge amounts of data...

We demonstrate the predictive power of a parametrised Doyle-Fuller-Newman (DFN) model commercial cylindrical (21700) lithium-ion cell with NCA/Gr-SiOx chemistry. Model parameters result from deconstruction fresh to determine/confirm chemistry and micro-structure, also electrochemical experiments half-cells built electrode samples. The simulations predict voltage profiles for (i) galvanostatic d...

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 ...

Embedded Systems are inherently heterogeneous. Thus, a model with a variety of perspectives for the representation of the embedded system functionality is of major interest in the design methodology. The underlying heterogeneity of an embedded system specification comes from (a) the existence of a mixed hardware/software structure for efficiently meeting the designer constraints and (b) the nee...

We present a topology-based method for mesh-partitioning in three-dimensional discrete fracture network (DFN) simulations that takes advantage of the intrinsic multi-level nature DFN. DFN models are used to simulate flow and transport through low-permeability fractured media subsurface by explicitly representing fractures as entities. The governing equations numerically integrated on computatio...
