Eddy Currents and Corner Singularities [PDF]

IEEE Transactions on Magnetics, 2012
Eddy current problems are addressed in this paper, in a bidimensional setting where the conducting medium is non-magnetic and has a corner singularity. For any fixed skin depth we show that the flux density is bounded near the corner, unlike the perfect conducting case.

Eddy impacts on the Florida Current [PDF]

Geophysical Research Letters, 2013
The Gulf Stream in the Atlantic carries warm water northwards and forms both the return closure of the subtropical gyre as well as the upper limb of the meridional overturning circulation. Recent time series recorded east of the Bahamas at 26°N indicate that from May 2009 to April 2011, in contrast with past observations, the northward flowing Antilles

Damage detection of cracks in carbon fibre reinforced composites by pulsed eddy-current testing

MATEC Web of Conferences, 2018
Non-destructive evaluation techniques that are based on electromagnetic methods are commonly used for inspection of metallic and carbon fibre reinforced plastics parts. Some of these inspection methods are based on eddycurrents which are generated by the

Methodology for Eddy Current Losses Calculation in Linear Variable Differential Transformers (LVDTs)

Sensors, 2023
Linear variable differential transformer (LVDT) is a commonly used linear displacement sensor because of its good measurement characteristics. When using laminated ferromagnetic cores in LVDTs, it is very important to take eddy currents into the account ...

Numerical Homogenization for the Calculation of Eddy Current Losses in a Laminated Open Core

IEEE Access
Eddy currents are decoupled into narrow eddy currents, induced by the magnetic flux tangential to the laminations, and planar eddy currents, induced by the magnetic flux perpendicular to the laminations.

ENSO Modulates Mean Currents and Mesoscale Eddies in the Caribbean Sea

Geophysical Research Letters, 2023
Although El Niño‐Southern Oscillation (ENSO) and its global impacts through teleconnection have been known for decades, if and how the mean currents and mesoscale eddies in the Caribbean Sea are linked to ENSO remains an open question. Here, by analyzing

Differential expression of cancer‐related genes supports prediction of poor response to first‐line treatments in T‐ALL pediatric patients with high minimal residual disease

Molecular Oncology, EarlyView.
In the present work, we have identified a transcriptional signature based on the differential expression of six genes (BCL2&MAST4, HSH2D&LAT2, METRN&PITPNM2) that would facilitate the early detection of T‐cell acute lymphoblastic leukemia (T‐ALL) patients prone to a poor treatment response and could be implemented at diagnosis, along with other risk ...
