(SciTePressPE, 2021)
"Human emotion recognition from visual expressions is an important research area in computer vision and machine learning owing to its significant scientific and commercial potential. Since visual expressions can be captured ...
Estudo das características modais de um modelo de aeronave em alumínio
(Universidade Estadual Paulista (Unesp), 2016-12-02)
A análise modal experimental é uma das técnicas mais importantes na caracterização dinâmica de estruturas. No setor aeroespacial a analise modal experimental é conhecida como Ground Vibration Test (GVT). Na Força Aérea ...
Alternative Phase-domain Model for Multi-conductor Transmission Lines Using Two Modal Transformation Matrices
(2016-02-07)
A new model for multi-conductor transmission lines is proposed based on an alternative modal decoupling technique. The line decoupling is accomplished using two modal transformation matrices: the real and constant Clarke's ...
Reliability of using stereo photogrammetry to estimate modal parameters
(2017-01-01)
Stereophotogrammetry is a three-dimensional full-field measurement technique that has gained more importance in the area of modal analysis in the past few years. In this technique, full-field data can be taken in a single ...
