Ablation of sources identified by dominant frequency (DF) or phase analyses in patients with atrial fibrillation (AF) is proposed as a therapy to terminate the arrhythmia. The aim of this study was to evaluate noninvasive identification of AF sources by solving the inverse problem. Realistic mathematical models of atria and torso anatomy with different DF patterns of AF were used. For these models...
A cross-adaptive mixing device has been developed for the purpose of optimizing the gain levels of a live audio mixture. The method aims to achieve optimal mixing levels by optimizing the ratios between the loudness of each individual input channel and the overall loudness contained in a stereo mix. In order to evaluate the amount of loudness of each channel in real-time, accumulative statistical...
This paper is focused on the analysis of a Kalman filter performance when introduced in the current control loop of a distributed generator connection inverter. The goal is to use this kind of filter to reduce the harmonic content of the currents injected by this equipment in their point of common coupling. The study has been performed by means of simulation, using Matlab-Simulink, and by implementing...
Interactive software demonstrations and computer-based exercises are often applied in signal processing education to examine concepts such as complex numbers, signal representation, sampling theory, and digital filter specification. While engineering software development environments such as National Instruments LabVIEW simplify the creation of such software, it's clear that some do a better job of...
