Social conflict analysis on a mining project using shannon entropy
(Institute of Electrical and Electronics Engineers Inc., 2017-08)
Social conflicts in the world have increased, due to the fact that the natural resources is being over exploited. In this work, we conducted a social conflict analysis using the entropy-weight method, which is based on ...
Structural, electronic, and magnetic entropy contributions of the orbital order-disorder transition in LaMnO(3)
(TAYLOR & FRANCIS LTD, 2011)
Measurements of X-ray diffraction, electrical resistivity, and magnetization are reported across the Jahn-Teller phase transition in LaMnO(3). Using a thermodynamic equation, we obtained the pressure derivative of the ...

(Universidade Federal de São CarlosUFSCarPrograma de Mestrado Nacional Profissional em Ensino de Física - PROFIS-SoCâmpus São Carlos, 2016-08-01)
This dissertation is intended to be used by high school teachers and contains
a set of concepts that leads to the understanding of entropy and its applications in the
classroom. It begins with the definition of thermodynamics, ...
Application of permutation entropy and permutation min-entropy in multiple emotional states analysis of RRI time series
(Molecular Diversity Preservation International, 2018-02)
This study?s aim was to apply permutation entropy (PE) and permutation min-entropy (PME) over an RR interval time series to quantify the changes in cardiac activity among multiple emotional states. Electrocardiogram (ECG) ...
Relative entropy and holography
(Springer, 2013-08-12)
Relative entropy between two states in the same Hilbert space is a fundamental statistical measure of the distance between these states. Relative entropy is always positive and increasing with the system size. Interestingly, ...
Meditation Increases the Entropy of Brain Oscillatory Activity
(Pergamon-Elsevier Science Ltd, 2020-04-01)
We address the hypothesis that the entropy of neural dynamics indexes the intensity and quality of conscious content. Previous work established that serotonergic psychedelics can have a dysregulating effect on brain activity, ...
Multi-lag analysis of symbolic entropies on EEG recordings for distress recognition
(Frontiers Media S.A., 2019-05)
Distress is a critical problem in developed societies given its long-term negative effects on physical and mental health. The interest in studying this emotion has notably increased during last years, being electroencephalography ...
Meditation increases the entropy of brain oscillatory activity
(Elsevier, 2020)
Abstract: We address the hypothesis that the entropy of neural dynamics indexes the intensity and quality of
conscious content. Previous work established that serotonergic psychedelics can have a dysregulating effect
on ...
