Optical monitoring in southern blazars. Analysis of variability and spectral colour behaviours
L. Zibecchi, I. Andruchow, E. Ej. Marchesini +2
We present the results of the optical monitoring of 18 southern blazars in the V and R Johnson-Cousins bands. Our main objective is to study the variations in the optical flux and…
D-shaped body wake control through flexible filaments
J. C. Muñoz-Hervás, B. Semin, M. Lorite-Díez +4
In this study, we investigate the flow around a canonical blunt body, specifically a D-shaped body of width , in a closed water channel. Our goal is to explore near-wake flow mo…
Classification of Adventitious Sounds Combining Cochleogram and Vision Transformers
Loredana Daria Mang, Francisco David Gonzalez Martinez, Damian Martinez Munoz +2
Early identification of respiratory irregularities is critical for improving lung health and reducing global mortality rates. The analysis of respiratory sounds plays a significant…
An ambient denoising method based on multi-channel non-negative matrix factorization for wheezing detection
Antonio J. Muñoz-Montoro, Pablo Revuelta-Sanz, Damian Martínez-Muñoz +2
In this paper, a parallel computing method is proposed to perform the background denoising and wheezing detection from a multi-channel recording captured during the auscultation pr…
Unsupervised detection and classification of heartbeats using the dissimilarity matrix in PCG signals
J. Torre-Cruz, D. Martinez-Munoz, N. Ruiz-Reyes +3
The proposed system consists of a two-stage cascade. The first stage performs a rough heartbeat detection while the second stage refines the previous one, improving the temporal lo…
An incremental algorithm based on multichannel non-negative matrix partial co-factorization for ambient denoising in auscultation
Juan De La Torre Cruz, Francisco Jesus Canadas Quesada, Damian Martinez-Munoz +3
The aim of this study is to implement a method to remove ambient noise in biomedical sounds captured in auscultation. We propose an incremental approach based on multichannel non-n…
