Análise experimental do ensaio veicular de imunidade a campos eletromagnéticos radiados em câmara semi-anecóica de pequeno porte
(Universidade Federal de Minas GeraisUFMG, 2007-10-26)
A few years ago, the self-driven vehicles were essentially provided withmechanical systems, used to perform many type of control functions.In the last decades, the development of the technology of the information,the ...
Gravitomagnetismo e o teste da sonda gravidade B
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em FísicaFísica da Matéria Condensada; Astrofísica e Cosmologia; Física da Ionosfera, 2011-07-01)
The so-called gravitomagnetic field arised as an old conjecture that currents of
matter (no charges) would produce gravitational effects similar to those produced by electric
currents in electromagnetism. Hans Thirring ...
Portadores quentes: modelo browniano
(Universidade Estadual Paulista (Unesp), 2011-02-17)
Neste trabalho estudamos o modelo do movimento Browniano de uma partícula carregada sob a ação de campos elétrico e magnético, externos e homogêneos, no formalismo de Langevin. Calculamos a energia cinética média através ...
Utilização de magnetorresistores no desenvolvimento de novas técnicas para aplicações em gastroenterologia
(Universidade Estadual Paulista (Unesp), 2009-10-16)
Biomagnetic techniques have been employed successfully to study gastrointestinal (GI) tract. They are enable to measure the magnetic field of magnetized markers, the markers and tracers responses to applied magnetic field ...
Propriedades magnéticas de BiMn2O5 e Fe3O2BO3
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2018-02-26)
In this work, an exploration of the synthesis and magnetoelectric properties of single-crystals of BiMn2O5 and a systematic study of the magnetic properties of Fe3O2BO3 are presented. Despite the unlike composition, both ...
Cientometria aplicada a materiais para armazenamento de hidrogênio
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2014-09-18)
Fossil Fuels have been used for more than a century as energy sources and vectors. Albeit their high energy densities and easy transport and containment, their availability is limited and they are notorious local pollution ...
Dipolaritons in quantum dots
(2015-11-16)
Abstract. Dipolaritons are quasiparticles that arise in coupled quantum wells embedded in a microcavity, they are a superposition of a photon, a direct exciton and an indirect exciton. An interesting feature of dipolaritons ...
