The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
(2002-12-01)
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...

The equatorial electrojet radar observations and modeling
(Cornell University, 2006-08)
This dissertation describes a theoretical, experimental, and modeling investigation of the equatorial electrojet. We review low latitude ionospheric current models, synthesizing developments from the early times until the ...
Influence of fixed electric charges on potential profile across the squid axon membrane
(ELSEVIER SCIENCE BV, 2008)
The potential profile for a model of squid axon membrane has been determined for two physiological states: resting and action states. The non-linear Poisson-Boltzmann equation has been solved by considering the volumetric ...
Analysis of the response of suspended colloidal soft particles to a constant electric field
(Elsevier, 2005-12)
A network model, originally designed for an electrokinetic study of soft particle suspensions, has been used for an in depth analysis of the physical behavior of these systems under the action of an externally applied DC ...
Transient electrical double layer dynamics in a quiescent fluid
(Institute of Electrical and Electronics Engineers, 2014-02)
From the moment a liquid is put in contact with a solid, physico-chemical reactions occur at their interface. These reactions have been modeled over the years by preferential adsorption or corrosion. Whatever the model, ...
Ionospheric and thermospheric variations associated with prompt penetration electric fields
(American Geophysical Union, 2012-08-10)
This paper presents a comprehensive modeling investigation of ionospheric and thermospheric variations during a prompt penetration electric field (PPEF) event that took place on 9 November 2004, using the Thermosphere‐Io ...
Low‐ and mid‐latitude ionospheric electric fields during the January 1984 GISMOS Campaign
(American Geophysical Union, 1990-03)
An alternative approach for estimating E region density profiles using radio occultation total electron content (ROTEC) measurements is presented. In this approach, the F region contribution to the measured ROTEC is removed ...
Transport control in fusion plasmas by changing electric and magnetic field spatial profiles
(ELSEVIER SCIENCE BV, 2009)
For magnetically confined plasmas in tokamaks, we have numerically investigated how Lagrangian chaos at the plasma edge affects the plasma confinement. Initially, we have considered the chaotic motion of particles in an ...
