چکیده
Nitrogen Sorption, Mercury Porosimetry, and Nuclear Magnetic Resonance Cryoporometry are characterization techniques used to obtain qualitative quantitative information about the textural properties of porous materials. The physical phenomena exploited in each technique related mechanical thermodynamic equilibria conditioned by pore blocking. latter phenomenon becomes relevant highly disordered solids with a broad size distribution multilevel organization. listed above contain topological shape their characteristic curves. In this work, it is shown how network model can be characterized numerically using computationally efficient algorithms for technique. These combine equilibrium conditions invasion percolation considerations. Such simulation tools form basis more comprehensive treatment experimental curves

An Irregular Lattice Pore Network Model Construction Algorithm
Pore network modeling uses a network of pores connected by throats to model the void space of a porous medium and tries to predict its various characteristics during multiphase flow of various fluids. In most cases, a non-realistic regular lattice of pores is used to model the characteristics of a porous medium. Although some methodologies for extracting geologically realistic irregular net...
متن کاملFast digitizing techniques applied to scintillation detectors
A 200 MHz 12-bit fast transient recorder card has been used for the digitization of pulses from photomultipliers coupled to organic scintillation detectors. Two modes of operation have been developed at ENEA-Frascati: a) continuous acquisition up to a maximum duration of ∼ 1.3 s corresponding to the full on-board memory (256 MSamples) of the card: in this mode, all scintillation events are reco...
متن کاملNonlinear Optimal Control Techniques Applied to a Launch Vehicle Autopilot
This paper presents an application of the nonlinear optimal control techniques to the design of launch vehicle autopilots. The optimal control is given by the solution to the Hamilton-Jacobi-Bellman (HJB) equation, which in this case cannot be solved explicity. A method based upon Successive Galerkin Approximation (SGA), is used to obtain an approximate optimal solution. Simulation results invo...
متن کاملComputational optimization techniques applied to microgrids planning: a review
Microgrids are expected to become part of the next electric power system evolution, not only in rural and remote areas but also in urban communities. Since microgrids are expected to coexist with traditional power grids (such as district heating does with traditional heating systems), their planning process must be addressed to economic feasibility, as a long-term stability guarantee. Planning ...
متن کاملHarmonics Estimation in Power Systems using a Fast Hybrid Algorithm
In this paper a novel hybrid algorithm for harmonics estimation in power systems is proposed. The estimation of the harmonic components is a nonlinear problem due to the nonlinearity of phase of sinusoids in distorted waveforms. Most researchers implemented nonlinear methods to extract the harmonic parameters. However, nonlinear methods for amplitude estimation increase time of convergence. Hen...
