Analysis of discrete least squares on multivariate polynomial spaces with evaluations at low-discrepancy point sets

Fabio Nobile, Giovanni Migliorati

We analyze the stability and accuracy of discrete least squares on multivariate polynomial spaces to approximate a given function depending on a multivariate random variable uniformly distributed on a hypercube. The polynomial approximation is calculated s ...

Analytical Form of Shepp-Logan Phantom for Parallel MRI

Michaël Unser, Dimitri Nestor Alice Van De Ville, Matthieu Guerquin-Kern

We present an analytical form of ground-truth k-space data for the 2-D Shepp-Logan brain phantom in the presence of multiple and non-homogeneous receiving coils. The analytical form allows us to conduct realistic simulations and validations of reconstructi ...

Improved Modeling of Three-Phase Transformer Analysis Based on Magnetic Equivalent Circuit Diagrams And Taking Into Account Nonlinear B-H Curve

Jean-Jacques Simond, Basile Kawkabani

The present paper deals with a new approach for the study of the steady-state and transient behaviour of phase transformers. This approach based on magnetic equivalent circuit diagrams, takes into account the nonlinear B-H curves as well as zero-sequence f ...
