Smoothing Before Estimating Uncertainty, Scaling, and Intermittency: Application to Short Heart Rate Signals
Three aspects of time series are uncertainty (dispersion at a given time scale), scaling (time-scale dependence), and intermittency (inclination to change dynamics). Simple measures of dispersion are the mean absolute deviation and the standard deviation; scaling exponents describe how dispersions change with the time scale. Intermittency has been defined as a difference between two scaling exp...
متن کاملNeuro-Fuzzy Modelling of Heart Rate Signals and Application to Diagnostics
Heart rate variability (HRV) is examined by methods combining neural networks and fuzzy logic. Multiple features are extracted from examples of heart rate data from normal adult subjects, subjects recently suffering from a heart attack, subjects with a history of ischaemic heart disease undergoing a coronary investigation, and subjects in atrial fibrillation. Special attention is given to the a...
متن کاملn-Order and maximum fuzzy similarity entropy for discrimination of signals of different complexity: Application to fetal heart rate signals
This paper presents two new concepts for discrimination of signals of different complexity. The first focused initially on solving the problem of setting entropy descriptors by varying the pattern size instead of the tolerance. This led to the search for the optimal pattern size that maximized the similarity entropy. The second paradigm was based on the n-order similarity entropy that encompass...
متن کاملconstruction and validation of translation metacognitive strategy questionnaire and its application to translation quality
like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
Scaling laws and intermittency in phase turbulence
2014 We investigate numerically the statistical properties of the Kuramoto-SivashinskyTsuzuki model [1-3], which describes the phase fluctuations of extended systems near the transition to turbulence. This model has some similarities with hydrodynamic turbulence [4]. The time fluctuations exhibit an unexpected scaling corresponding to anomalous diffusion of the phase. Other results also point t...
