Modeling of Effect of Plastic Deformation on Barkhausen Noise and Magnetoacoustic Emission in Iron With 2% Silicon
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2008)
Before one models the effect of plastic deformation on magnetoacoustic emission (MAE), one must first treat non-180 degrees domain wall motion. In this paper, we take the Alessandro-Beatrice-Bertotti-Montorsi (ABBM) model ...
Lack of magnetoacoustic emission in iron with 6.5% silicon
(ELSEVIER SCIENCE BV, 2008)
The phenomenon of magnetoacoustic emission (MAE) has been ascribed usually to one of two origins: either (1) motion of non-180 degrees domain walls or (2) creation or annihilation of domains. In this paper, we present ...
Impact of plastic deformation on magnetoacoustic properties of Fe-2%Si alloy
(ELSEVIER SCI LTD, 2009)
The paper presents the results of a complementary study including magnetic hysteresis loops B(H), magnetic Barkhausen noise (MBN) and magnetoacoustic emission (MAE) signals measurements for plastically deformed Fe-2%Si ...
Estudio numérico y observacional de la dinámica del plasma en la propagación de ondas en manchas solares y en la deflexión de eyecciones coronales de masa
(2019-03)
En esta tesis se estudiaron fundamentalmente dos procesos, la propagación de perturbaciones periódicas en una región activa asociada a una mancha solar y las deflexiones de eyecciones coronales de masa. Se presenta la ...
On the generation of subphotospheric acoustic sources
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - AstronomíaObservatorio Astronómico NacionalFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2021)
This work explored the possibility of the generation of seismic signals on the Sun from a confinement of energy located in the solar interior. This idea was developed through two sections. In the first section, corresponding ...
