Termodinâmica de um gelo de spin artificial regravável
(Universidade Federal de Minas GeraisUFMG, 2018-06-29)
Artificial spin ices (ASI) are geometrically frustrated, two-dimensional arrays of magnetic nanoislands, originally designed to mimic the behavior of pyrochlore spin ice materials. Different types of ASI have been developed ...
Sistema de sensoriamento eletromagnético utilizado para detecção da contaminação do óleo isolante do motor no método de elevação artificial do tipo bombeio centrífugo submerso
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia do PetróleoPesquisa e Desenvolvimento em Ciência e Engenharia de Petróleo, 2010-02-25)
In the artificial lift method by Electrical Submersible Pump (ESP), the energy is
transmitted for the well´s deep through a flat electric handle, where it is converted into
mechanical energy through an engine of sub-surface, ...
Size- And temperature-dependent magnetization of iron nanoclusters
(American Physical Society, 2020-11)
The magnetic behavior of bcc iron nanoclusters, with diameters between 2 and 8 nm, is investigated by means of spin dynamics simulations coupled to molecular dynamics, using a distance-dependent exchange interaction. ...
Artificial Pinning Center Studies in BI2212 Tapes and Bulks With Zirconium Oxide Inclusion
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2009)
Zirconium oxide inclusion in Bi2212 superconducting tapes and bulks was studied as possible artificial pinning centers (APC). In order to analyze the zirconium oxide APC addition in Bi2212 samples, magnetization measurements ...
Sistema estabilizador da adesão de um robô escalador com rodas magnéticas
(Universidade Tecnológica Federal do ParanáCuritibaPrograma de Pós-Graduação em Engenharia Elétrica e Informática Industrial, 2014-07-23)
This work consists in the design of an adhesion stabilization system of a climbing robot with magnetic wheels. The robot’s design comes from the need to automatize the inspection process of industrial storage tanks for ...
The violation of the Hund rule in semiconductor artificial atoms
(2004)
The unrestricted Pople–Nesbet approach for real atoms is adapted to quantum dots under applied magnetic field. Gaussian basis sets are used instead of the exact single-particle orbitals in the construction of the appropriated ...
Magnetotransport in a wide parabolic well superimposed with a superlattice
(AMER INST PHYSICS, 2011)
The electron properties of artificially disordered superlattices embedded in a wide AlGaAs parabolic well were investigated in a strong magnetic field. We demonstrated that in the extreme quantum limit the interlayer ...
Vortex pinning vs superconducting wire network: origin of periodic oscillations induced by applied magnetic fields in superconducting films with arrays of nanomagnets
(IOP Publishing, 2014-08)
Hybrid magnetic arrays embedded in superconducting films are ideal systems to study the competition between different physical (such as the coherence length) and structural length scales such as are available in artificially ...
Artificial Intelligence in Cardiac MRI: Is Clinical Adoption Forthcoming?
(FRONTIERS MEDIA SA, 2022)
Artificial intelligence (AI) refers to the area of knowledge that develops computerised models to perform tasks that typically require human intelligence. These algorithms are programmed to learn and identify patterns from ...
