the meshless local radial point interpolation (mlrpi) method is applied to examine the magnetohydrodynamic (mhd) ow of third grade uid in a porous medium. the uid saturates the porous space between the two boundaries. several limiting cases of fundamental ows can be obtained as the special cases of present analysis. the variations of pertinent parameters are addressed.

We consider the following question: given an (X, Y )-bigraph G and a set S ⊆ X, does G contain two disjoint matchings M1 and M2 such that M1 saturates X and M2 saturates S? When |S| ≥ |X| − 1, this question is solvable by finding an appropriate factor of the graph. In contrast, we show that when S is allowed to be an arbitrary subset of X, the problem is NP-hard.

The impact of synchronous inputs onto a simple neuron model with synapses showing shortterm plasticity is studied. The synaptic model includes depression, stochastic release and facilitation. The mean and second-order statistics of the current are computed. The combination of synchrony and STP produces a non-monotonic behavior of the current variance , while the mean saturates monotonically. Pr...

At present, the regeneration agent with mineral oil as main component is widely used. However, its strong volatility, nonrenewability, and other shortcomings restrict development of technology. In this study, waste vegetable was used to prepare regenerated aging asphalt. The change in microstructure asphalt explored content time. results showed that addition could effectively supplement content...

We incorporate CO2 dissolution due to convective mixing into a sharp-interface mathematical model for the post-injection migration of a plume of CO2 in a saline aquifer. The model captures CO2 migration due to groundwater flow and aquifer slope, as well as residual trapping and dissolution. We also account for the tongued shape of the plume at the end of the injection period. We solve the model...

Intense magnetic dipole scattering that has been observed recently in several transparent insulators arises nonlinearly and saturates as predicted by classical theory, but also varies with electronic structure of the medium. & 2009 Published by Elsevier B.V.
