Cross-entropy optimizer: a new tool to study precession in astrophysical jets
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Evidence of jet precession in many galactic and extragalactic sources has been reported in the literature. Much of this evidence is based on studies of the kinematics of the jet knots, which depends on the correct ...
MODELING VERY LONG BASELINE INTERFEROMETRIC IMAGES WITH THE CROSS-ENTROPY GLOBAL OPTIMIZATION TECHNIQUE
(IOP PUBLISHING LTD, 2011)
We present a new technique for obtaining model fittings to very long baseline interferometric images of astrophysical jets. The method minimizes a performance function proportional to the sum of the squared difference ...
The Cross-Entropy Method and its Application to Minimize the Ripple of the Magnetic levitating Forces of a Maglev System
(Japan Society Applied Electromagnetics & Mechanics, 2009-01-01)
The Cross-Entropy (CE) method is developed and applied to minimize the ripple of the magnetic levitating forces of a maglev system with promising results.
Multidimensional and fuzzy sample entropy (SampEnMF) for quantifying H&E histological images of colorectal cancer
(2018-12-01)
In this study, we propose to use a method based on the combination of sample entropy with multiscale and multidimensional approaches, along with a fuzzy function. The model was applied to quantify and classify H&E histological ...
Computational analysis of third-grade liquid flow with cross diffusion effects: application to entropy modeling
(Corporación Universidad de la Costa, 2021)
ALICCE: Atomic Lines Calibration using the Cross-Entropy algorithm
(Oxford University PressOxford, 2014)
Atomic line opacities play a crucial role in stellar astrophysics. They strongly modify the
radiative transfer in stars, therefore, impacting their physical structure. Ultimately, most of our
knowledge of stellar population ...
Transition to Adulthood in Spain: a Temporal and Territorial Comparison Using Entropy Analysis

Análise da fadiga muscular por meio de sinais eletromiográficos utilizando medidas de informação
(Universidade Tecnológica Federal do ParanáCornelio ProcopioBrasilPrograma de Pós-Graduação em Engenharia ElétricaUTFPR, 2017-12-07)
The analysis of human movement and muscular fatigue is widely studied through the electromyo- graphy signal. For this work, we used electromyography signals that were assigned to the study and that came from a non-invasive ...
Acoustic investigation of speech pathologies based on the discriminative paraconsistent machine (DPM)
(2020-01-01)
Background: Voice disorders are related to both modest and severe health problems, including discomfort, pain, difficulty speaking, dysphagia and also cancer. Widely adopted worldwide, the combined invasive and subjective ...
