In this paper, a state observer is proposed for the reconstruction of the concentration profiles in a simulated moving bed. The approach is based on a simple Luenberger-like correction term. Validating simulations are proposed to assess the efficiency of the proposed profile reconstruction and its robustness against uncertainties on modelling parameters. Comparisons are also done with open-loop...

the long-term efficacy of written grammar feedback (wgf) has escaped rigorous empirical investigation, partly due to its strong intuitive appeal. the few studies that have investigated the long-term effect of grammar correction have failed to find any positive long-term effects for wgf (truscott, 2007). nevertheless, a number of recent studies have reported a positive effect for wgf. the presen...

The Gauss self-linking integral of an unframed knot is not a knot invariant, but it can be turned into an isotopy invariant by adding a correction term which requires adding extra structure to the knot. We collect the different definitions/theorems/proofs concerning this correction term, most of which are well-known (at least as folklore) and put everything together in an accessible format. We ...

The origin of the spurious interface velocity in finite difference lattice Boltzmann models for liquid vapor systems is related to the first order upwind scheme used to compute the space derivatives in the evolution equations. A correction force term is introduced to eliminate the spurious velocity. The correction term helps to recover sharp interfaces and sets the phase diagram close to the on...

2014 New perimeter polynomials (in dimensions d = 2 to 4) are analysed for directed site percolation. A study of these data shows that i) above pc the average perimeter-to-sizeratio varies as 03B1 = (1 2014 p)/p + Bs-1/d; ii) At pc its leading correction term estimates supports the prediction (from scaling) of an exponent equal to 1/0394 2014 1 (with 0394 the gap exponent for directed percolati...

A simple phase error correction technique used for field map estimation with a generally available dual-echo gradient-echo (GRE) sequence is presented. Magnetic field inhomogeneity maps estimated using two separate GRE volume acquisitions at different echo times are prone to dynamic motion errors between acquisitions. By using the dual-echo sequence, the data are collected during two back-to-ba...

We study the gauge coupling unification with extra dimensions. We take into account corrections due to the higher dimensional operators. We show the prediction of α3(MZ) is sensitive to such corrections, even if c < Φ > /M = O(0.01). We also discuss the b − τ Yukawa unification. Partially supported by the Academy of Finland (no. 44129). Recently, theories with large extra dimensions have been s...

We calculate perturbatively the normalized spatial skewness, S3, and full three-point correlation function (3PCF), ζ , induced by gravitational instability of Gaussian primordial fluctuations for a biased tracer-mass distribution in flat and open cold-dark-matter (CDM) models. We take into account the explicit dependence on cosmological parameters, the shape and evolution of the CDM power spect...

Large O(m −2 c) nonperturbative correction to the inclusive rate of the decay B → X s γ. Abstract It is shown that the inclusive rate of the rare weak radiative decays B → X s γ contains a nonperturbative correction, whose 'short distance' scale is set by m −1 c rather than by m −1 b. This correction is expressed through the chromomagnetic interaction of the b quark inside the B meson and the r...
