On the continuity of the magnetizing current density in 3-D magnetic field analysis with edge element [PDF]

open access: yes, 1995
The effects of the continuity of the magnetizing current density on the convergence of the incomplete Cholesky conjugate gradient method and the accuracy of the calculated flux densities are investigated by imposing different continuity conditions for ...

The design of a hybrid DC/DC converter for LED lighting system using a single switch

open access: yesEnergy Reports, 2023
A novel hybrid Luo-Cuk converter designed for LED lighting systems combines elements from both Luo and Cuk topologies. By integrating the input branch of both topologies, the converter, employing a single switch, can generate two distinct types of ...

Improved analytical model for predicting the magnetic field distribution in brushless permanent-magnet machines [PDF]

open access: yes, 2002
A general analytical technique predicts the magnetic field distribution in brushless permanent magnet machines equipped with surface-mounted magnets. It accounts for the effects of both the magnets and the stator windings.

Magnetic light [PDF]

open access: yesScientific Reports, 2012
Spherical silicon nanoparticles with sizes of a few hundreds of nanometers represent a unique optical system. According to theoretical predictions based on Mie theory they can exhibit strong magnetic resonances in the visible spectral range. The basic mechanism of excitation of such modes inside the nanoparticles is very similar to that of split-ring ...

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

Three-Phase Busbar Current Transducer [PDF]

open access: yes, 2019
A true three-phase 1000 A busbar current transducer is based on six micro-fluxgate sensors. Instead of using three independent single-phase current transducers, we use the full information from each sensor.
