An Array Recursive Least-Squares Algorithm With Generic Nonfading Regularization Matrix
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)
We present a novel array RLS algorithm with forgetting factor that circumvents the problem of fading regularization, inherent to the standard exponentially-weighted RLS, by allowing for time-varying regularization matrices ...
Sparse Array Design Using the Genetic Algorithm for Optimizing the Radiation Pattern of Linear Arrays
(2019-01-01)
The genetic algorithm was used to obtain sparse arrays with 8, 16, 32 and 64 transducers in a possible aperture size of 128 elements. The optimization was made by minimizing a fitness function that takes into account the ...
Técnicas para obtenção de arrays lineares esparsos usando algoritmo genético
(Universidade Estadual Paulista (Unesp), 2018-08-31)
O ultrassom pode ser utilizado para gerar imagens aplicadas aos ensaios não destrutivos (END) e diagnóstico médico, em que arrays são utilizados para obter imagens com melhor resolução lateral e contraste em relação a um ...
Optimization in ultrasonic imaging systems: Use of metaheuristics to design sparse arrays and a heuristic to create an acquisiton system
(Universidade Estadual Paulista (Unesp), 2022-09-02)
Ultrasonic images have an important contribution to medical diagnosis and nondestructive testing. One strategy to generate an image is to use an array, which is a transducer composed of a set of piezoelectric elements, ...

The effects of pinning on critical currents of superconducting films
(2013-06-01)
Using molecular dynamics simulations, we analyze the effects of artificial periodic arrays of pinning sites on the critical current of superconducting thin films as a function of vortex density. We analyze two types of ...
