On a correlation between the ionospheric electric field and the time derivative of the magnetic field
(Hindawi, 2012-02-20)
A correlation of the ionospheric electric field and the time derivative of the magnetic field was noticed over thirty years ago and has yet to be explained. Here we report on another set of examples during the superstorm ...
Obtaining accurate and calibrated coil models for transcranial magnetic stimulation using magnetic field measurements
(Springer Heidelberg, 2020-07)
Currently, simulations of the induced currents in the brain produced by transcranial magnetic stimulation (TMS) are used to elucidate the regions reached by stimuli. However, models commonly found in the literature are too ...
Using Proton Nuclear Magnetic Resonance (NMR) as a calibrating reference for magnetic field measurement instruments: Sensitive volume and magnetic field homogeneity
(Elsevier, 2020-02)
Nuclear magnetic resonance can be conveniently used to set up reference values of magnetic flux densities for the calibration of measurement instrumentation. Two measurement procedures are proposed based on the Fourier ...
Electric field and magnetometer observations of the equatorial electrojet: An IEEY program
(Instituto Geofísico del Perú, Radio Observatorio de Jicamarca, 1994)
As part of the IEEY program, a chain of magnetometers was deployed along the Peruvian sector crossing the equatorial electrojet. Simultaneous vertical drift measurements were made using Jicamarca's normal I.S. F-region ...
Damage assessment in a sandwich panel based on full-field vibration measurements
(Academic Press, 2018)
Different studies have demonstrated that vibration characteristics are sensitive to
debonding in composite structures. Nevertheless, one of the main restrictions of vibration
measurements is the number of degrees of ...
The IFUSP race-track microtron booster accelerator end magnets antisymmetric perturbations
(Gordon Breach Sci Publ Ltd, 1999-01-01)
We will present measurements and calculations related to the antisymmetric perturbations, and comparisons with the symmetric ones, of the IFUSP race-track microtron booster accelerator end magnets. These perturbations were ...

Poincaré recurrence theorem for non-smooth vector fields
(2017-04-01)
In this paper, some ergodic aspects of non-smooth vector fields are studied. More specifically, the concepts of recurrence and invariance of a measure by a flow are discussed, and two versions of the classical Poincaré ...
Comparison of electric fields measured at F-region heights with 150 km - irregularity drift measurements
(1995)
The potential to observe the E-W electric field in the equatorial ionosphere using the strong coherent echoes obtained by the Jicamarca radar from irregularities present at the Magnetic Equator, in the altitude range between ...
