A deep learning framework for damage assessment of composite sandwich structures
(Hindawi, 2021)
The vibrational behavior of composite structures has been demonstrated as a useful feature for identifying debonding damage. The precision of the damage localization can be greatly improved by the addition of more measuring ...
Interface localized modes and hybrid lattice solitons in waveguide arrays
(2007)
We discuss the formation of guided modes localized at the interface separating two different periodic photonic lattices. Employing the effective discrete model, we analyze linear and nonlinear interface modes and also ...
Estudo do modo coletivo massivo do líquido de Fermi ferromagnético
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2014-02-25)
The present dissertation is divided in 4 chapters. From chapter 1 to 2, we review some basic concepts of the normal Fermi liquid theory (a set of interacting fermions in correspondence with the Fermi gas) such as quasiparticles, ...
Configurable Software Performance Completions through Higher-Order Model Transformations
Chillies is a novel approach for variable model transformations closing the gap between abstract architecture models, used for performance prediction, and required low-level details. We enable variability of transformations ...
REVISITING TERRITORIAL GOVERNANCE: INSTITUTIONAL DEVICES, INTERMEDIATE NOTIONS AND REGULATORY LEVELS
(Univ Federal Fluminense, 2017-09-01)
The word governance is not new. It goes through different periods of history and takes specific meanings in certain times and countries. Currently, the concept of governance can be defined as institutional procedures of ...
Localized modes in linear and nonlinear octagonal-diamond lattices with two flat bands
(Amer Physical Soc, 2020)
We consider a two-dimensional octagonal-diamond network with a fine-tuned diagonal coupling inside the diamond-shaped unit cell. Its linear spectrum exhibits coexistence of two dispersive bands (DBs) and two flat bands ...
Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...

Ondas de spin em paredes de domínio unidimensionais em monocamadas magnéticas
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2012-08-16)
Recent investigations on ferromagnetic monolayers predict the existence of spinwave modes without gap in the spectrum, even in the presence of anisotropy. These excitations propagate within the domain walls that exist in ...
