A self-parametrizing partition model approach to tomographic inverse problems [PDF]

open access: yesInverse Problems, 2009
Summary: Partition modelling is a statistical method for nonlinear regression and classification, and is particularly suited to dealing with spatially variable parameters. Previous applications include disease mapping in medical statistics. Here we extend this method to the seismic tomography problem.

On the parametrization of optical particle counter response including instrument-induced broadening of size spectra and a self-consistent evaluation of calibration measurements [PDF]

open access: yesAtmospheric Measurement Techniques, 2017
Optical particle counters (OPCs) are common tools for the in situ measurement of aerosol particle number size distributions. As the actual quantity measured by OPCs is the intensity of light scattered by individual particles, it is necessary to ...

Neighborhood Search Considering Continuous Space Search

open access: yesTrends in Computational and Applied Mathematics, 2002
The objective of this work is to present and discuss a dynamical optimization procedure based on the algorithm of self-consistent parametric inference, where the movement of one feasible solution to another is implemented in continuous mode. The approach

Quantum Correlations in the Minimal Scenario [PDF]

open access: yesQuantum, 2023
In the minimal scenario of quantum correlations, two parties can choose from two observables with two possible outcomes each. Probabilities are specified by four marginals and four correlations. The resulting four-dimensional convex body of correlations,

Computation of the matched envelope of the Danilov distribution

open access: yesPhysical Review Accelerators and Beams, 2021
For the purposes of this paper, we define self-consistent beams as those which give rise to linear internal electric fields and maintain this property under any linear transport.

Density Functional Treatment of Photoionization of Sodium Clusters: Effects of Cluster Size and Exchange–Correlation Framework

open access: yesAtoms, 2023
The ground state and photoionization properties of Nax (x = 20, 40, and 92) clusters are investigated using a method based on density functional theory (DFT) in a spherical jellium frame.
