Higher-spin states of the superstring in an electromagnetic background
(2021-12-01)
Constructing a consistent four-dimensional Lagrangian for charged massive higher-spin fields propagating in an electromagnetic background is an open problem. In 1989, Argyres and Nappi used bosonic open string field theory ...
Whole-Body SAR simulations on a prolate spheroid using different plane wave polarizations up to 100 GHz
(Instituto Tecnológico de Costa Rica, 2019)
Energy and momentum for the electromagnetic field described by three outstanding electrodynamics
(1997-09-01)
A prescription for computing the symmetric energy-momentum tensor from the field equations is presented. The method is then used to obtain the total energy and momentum for the electromagnetic field described by Maxwell ...
Effect of electromagnetic field on bone regeneration around dental implants after immediate placement in the dog mandible: a pilot study
(WILEY-BLACKWELLHOBOKEN, 2013-08-02)
Background: Accelerating bone healing around dental implants can reduce the long-term period between the insertion of implants and functional rehabilitation. Objective: This in vivo study evaluated the effect of a constant ...
Wavelet-galerkin method for computations of electromagnetic fields-computation of connection coefficients
(Institute of Electrical and Electronics Engineers (IEEE), 2000-12-01)
One of the key issues which makes the waveletGalerkin method unsuitable for solving general electromagnetic problems is a lack of exact representations of the connection coefficients. This paper presents the mathematical ...
Evaluation of pulsed electromagnetic field protocols in implant osseointegration: in vivo and in vitro study
(2021-05-01)
Objectives: The present study aims to evaluate two protocols of pulsed electromagnetic field (PEMF) on osseointegration and establish one that addresses ideal parameters for its use in dentistry, especially in the optimization ...
Using Equivalent Emission Sources to Evaluate the Coupling Between Components
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INCPISCATAWAY, 2012)
The electromagnetic interference between the electronic systems or their components influences the performance of the systems. For that reason, it is important to model these interferences in order to optimize the position ...
Projeto e teste de transformador monofásico toroidal
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de ElétricaEngenharia ElétricaUTFPR, 2021-04-19)
This final course work presents the design, implementation and testing of a single-phase toroidal transformer. First, a study was carried out on the concepts of electromagnetism that govern the working principle of ...
