Séparation adaptative de sources dans l'espace signal
Nous explorons la possibilité de coupler un algorithme adaptatif de séparation de sources avec un algorithme adaptatif de projection de projection sur l'espace signal afin de tirer parti d'un nombre de capteurs supérieur au nombre de sources.

Stable signal recovery in compressed sensing with a structured matrix perturbation [PDF]
The sparse signal recovery in the standard compressed sensing (CS) problem requires that the sensing matrix be known a priori. Such an ideal assumption may not be met in practical applications where various errors and fluctuations exist in the sensing ...

Le lissage H∞ : une alternative au filtrage de Kalman pour le rehaussement du signal de parole ?
- La mise en oeuvre d'un filtre de Kalman repose sur des hypothèses fortes sur le processus générateur et le bruit d'observation du système. En effet, ils doivent être tous les deux blancs et gaussiens et leurs variances connues a priori.

ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Algorithme génétique pour le rehaussement d'un signal de parole voisé fondé sur un modèle sinusoïdal
Parallèlement aux approches par atténuation spectrale à court terme, de nombreuses méthodes paramétriques ont été mises en oeuvre pour rehausser le signal de parole, capté par un unique microphone.

Modelling and studying the effect of graph errors in graph signal processing
Publisher Copyright: © 2021The first step for any graph signal processing (GSP) procedure is to learn the graph signal representation, i.e., to capture the dependence structure of the data into an adjacency matrix.

ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
