A systematic analysis for the quantitative comparison of phase retrieval methods based on alternating projections
(Elsevier, 2018-07)
We present a numerical and experimental scheme for the systematic analysis and comparison of phase retrieval techniques based on alternating projection numerical methods. This comparison allows us to evaluate the most ...
Three-state model with competing antiferromagnetic and pairing interactions
(American Physical Society, 2019-04-24)
Motivated by the rich phase diagram of the high-temperature superconductors, we introduce a pseudospin model with three state variables which can be interpreted as two states (spin ±1/2) particles and holes. The Hamiltonian ...
Open Transistors Fault-Tolerant Schemes of three-Phase Dual Active Bridge DC-DC Converters
(Institute of Electrical and Electronics Engineers, 2021-03)
This work proposes fault-tolerant schemes for open-transistor faults applied to three-phase dual active bridge converters (TPDABC), using different transformers: star-star, delta-delta, and delta-star. The proposal consists ...
Numerical Simulation of Conduction-Advection Problems with Phase Change
(Planta Piloto de Ingeniería Química, 2001-12)
This paper introduces a finite element temperature-based model to represent conduction-advection dominated heat transfer when the material is undergoing phase-change. A fixed domain method is applied, so that the energy ...
A new condition to identify isotropic dielectric-magnetic materials displaying negative phase velocity
(John Wiley & Sons Inc, 2004-12)
A new condition for characterizing isotropic materials with negative phase velocity was derived. The equivalence between this condition and its predecessors was also studied. A linear isotropic dielectric-magnetic medium ...
