Acoustic Imaging of In-Duct Aeroengine Noise Sources Using Rotating Beamforming and Phased Arrays
(Ieee-inst Electrical Electronics Engineers Inc, 2017-09-01)
An in-duct rotating beamforming technique, using a wall-mounted array of microphones placed within a long duct, was developed for locating broadband noise sources from an aeroengine fan. The technique was experimentally ...
Generalized inverse beamforming with optimized regularization strategy
(Academic Press Ltd- Elsevier Science LtdLondonInglaterra, 2011)
Técnicas avanzadas para la detección de fuentes sonoras
(2013-11)
En la actualidad existen diferentes tipos de técnicas para cuantificar y detectar la posición de una fuente sonora. Las técnicas modernas más utilizadas son las imágenes acústicas, éstas se obtienen mediante el proceso de ...
Estudos da técnica de beamforming combinando arranjos de microfones e material poroso
(Universidade Federal de Santa MariaBrasilEngenharia de ProduçãoUFSMPrograma de Pós-Graduação em Engenharia de ProduçãoCentro de Tecnologia, 2017-08-11)
In order to solve the problems caused by noise, it is essential that an adequate evaluation of the
main sources of noise is carried out. This can be done using an acoustic imaging technique and
one of them is the ...
Robust Minimmun Variance Beamformer using Phase Aberration Correction Methods
(Pontificia Universidad Católica del Perú, 2017)
Secure Beamforming for MIMO Broadcasting With Wireless Information and Power Transfer
(Elsevier, 2015-05)
We consider the Allen–Cahn equation Δu + u(1 − u2) = 0 in R3. We construct
two classes of axially symmetric solutions u = u(|x
|, x3) such that the (multiple)
components of the zero set look for large |x
| like catenoids, ...
Using GPUs for beamforming acceleration on SAFT imaging
(2009-12-01)
SAFT techniques are based on the sequential activation, in emission and reception, of the array elements and the post-processing of all the received signals to compose the image. Thus, the image generation can be divided ...
