The main objective of this paper is to develop a model which combines in the same process image classification and restoration.
Image classification consists of assigning a label to each site of an ...
Improving the Convergence of SU(3) Baryon Chiral Perturbation Theory
Baryon chiral perturbation theory the chiral expansion momentum space physics
font style='font-size:12px;'>
2014/12/23
Baryon chiral perturbation theory as conventionally applied using dimensional regularization has a well-known problem with the convergence of the SU(3) chiral expansion. One can reformulate the theory...
Regularization of Diagrammatic Series with Zero Convergence Radius

2014/12/19
The divergence of perturbative expansions which occurs for the vast majority of macroscopic systems and follows from Dyson’s collapse argument prevents the direct use of Feynman’s diagrammatic techniq...

In this paper, several discrete schemes for Gaussian curvature are sur-
veyed. The convergence property of a modi痚d discrete scheme for the
Gaussian curvature is proved. Furthermore, a new discrete ...
Convergence of many-body wavefunction expansions using a plane wave basis: from the homogeneous electron gas to the solid state
Convergence many-body wavefunction expansions plane wave basis homogeneous electron gas solid state

2012/2/29
Using the finite simulation-cell homogeneous electron gas (HEG) as a model, we investigate the convergence of the correlation energy to the complete basis set (CBS) limit in methods utilising plane-wa...
Convergence of phase noise in DPSK transmission systems by novel phase noise averagers

2011/11/23
This investigation proposes a novel all-optical phase noise averager to reduce residual phase noise in the differential phase-shift keying (DPSK) transmission system with phase-preserving amplitude re...
Convergence of repeated QND measurements and the wave function collapse
QND measurement the wave function collapse Quantum Physics
font style='font-size:12px;'>
2011/7/26
Abstract: Motivated by recent experiments on quantum trapped fields, we give a rigorous proof that repeated indirect quantum non-demolition (QND) measurements converge to the collapse of the wave func...

Abstract: The objective of the article is to treat the Schrodinger equation in parallel with a standard treatment of the heat equation. In the mathematics literature, the heat equation initial value p...
Stochastic sigma-convergence and applications
Dynamical system homogenization supralgebras Stokes equations

2011/7/27
Abstract: Motivated by the fact that in nature almost all phenomena behave randomly in some scales and deterministically in some other scales, we build up a framework suitable to tackle both determini...
Convergence of a renormalization group approach to dimer-dimer scattering
Convergence of a renormalization group dimer-dimer scattering
font style='font-size:12px;'>
2011/1/10
We study the convergence of a functional renormalisation group technique by looking at the ratio between the fermion-fermion scattering length and the dimer-dimer scattering length for a system of non...
Quantum singular operator limits of thin Dirichlet tubes via $\Gamma$-convergence
Quantum singular operator limits thin Dirichlet tubes $\Gamma$-convergence
font style='font-size:12px;'>
2010/11/11
The $\Gamma$-convergence of lower bounded quadratic forms is used to study the singular operator limit of thin tubes (i.e., the vanishing of the cross section diameter) of the Laplace operator with Di...
Numerical Feynman integrals for density operator dynamics using more than one mesh: faster convergence and significant reduction of computational cost

2010/10/26
The Feynman integral is one of the most accurate methods for calculating density operator dy-
namics in open quantum systems. However, the number of time steps that can realistically be used is alway...
