Self-organized criticality in MHD driven plasma edge turbulence
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
We analyze long-range time correlations and self-similar characteristics of the electrostatic turbulence at the plasma edge and scrape-off layer in the Tokamak Chauffage Alfven Bresillien (TCABR), with low and high ...
An efficient MHD equilibrium solver for control oriented transport models
(Elsevier Science SA, 2020-03)
In tokamak plasmas, the current density profile is a strong determiner of both MHD stability and confinement. The design of active control techniques for this profile relies on control oriented transport models that capture ...
Study of the fractality of magnetized plasma using an MHD shell model driven by solar wind data
(American Institute of Physics Inc., 2018)
An MHD shell model is used to describe the dissipative events that take place in magnetized plasmas. We analyze the activity of the time series of the magnetic energy dissipation rate obtained in the MHD shell model, which ...
Physical activity and energy expenditure in haemodialysis patients: an international survey
(Oxford Univ Press, 2012-06-01)
Background. the assessment of physical activity and energy expenditure is relevant to the care of maintenance haemodialysis (MHD) patients. in the current study, we aimed to evaluate measurements of physical activity and ...
TURBULENCE AND THE FORMATION OF FILAMENTS, LOOPS, AND SHOCK FRONTS IN NGC 1275
(IOP PUBLISHING LTD, 2010)
NGC 1275, the central galaxy in the Perseus cluster, is the host of gigantic hot bipolar bubbles inflated by active galactic nucleus (AGN) jets observed in the radio as Perseus A. It presents a spectacular H alpha-emitting ...
Steady-state magnetohydrodynamic flow around an unmagnetized conducting sphere
(IOP Publishing, 2014-07)
The non-collisional interaction between conducting obstacles and magnetized plasma winds can be found in different scenarios, from the interaction occurring between regions inside galaxy clusters to the inter- action between ...
A data-driven, two-temperature solar model with Alfven waves
(IOP Publishing, 2010-12-10)
We have developed a new three-dimensional magnetohydrodynamic (MHD) solar wind model coupled to the Space Weather Modeling Framework (SWMF), that solves for the different electron and proton temperatures. The collisions ...
Descifrando el clima espacial: ciclos solares y ondas magnéticas de Rossby
(Revista Uniciencia, Universidad Nacional, 2019-07)
El objetivo de esta investigación es explorar si existe una relación entre las ondas magnéticas de Rossby rápidas o lentas y ciertas observaciones de la actividad solar de largo y muy largo plazo (meses, años, décadas…). ...
Metodologia para simulações de arcos elétricos aplicada ao estudo de energia incidente em sistemas elétricos de potência
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2022-01-27)
Electric arcs are phenomena that occur when the ionization of the air is sufficient
to allow the flow of electric current, which can occur due to the separation of energized
contacts, such as during the opening of switching ...
Two step mechanism for Moreton wave excitations in a blast-wave scenario: The 2006 December 06 case study
(Wiley Blackwell Publishing, Inc, 2015-10)
We examine the capability of a blast-wave scenario - associated with a coronal flare or to the expansion of CME flanks - to reproduce a chromospheric Moreton phenomenon. We also simulate the Moreton event of 2006 December ...
