Implementation of real-time digital filter for the R wave detection
TecnoLógicas, 2015 Quantification of the instantaneous heart rate is based on the detection of the R wave of the electrocardiographic signal. This process requires the implementation of strategies for real-time filtering for the time of occurrence of each R wave.

A review of numerical asymptotic averaging for weakly nonlinear hyperbolic waves
Mathematical Modelling and Analysis, 2004 We present an overview of averaging method for solving weakly nonlinear hyperbolic systems. An asymptotic solution is constructed, which is uniformly valid in the “large” domain of variables t + |x| ∼ O(ϵ –1).

Eigenstate Thermalization and Disorder Averaging in Gravity. [PDF]
Physical Review Letters, 2020 Naively, resolving the black hole information paradox requires microscopic details about quantum gravity. Recent work suggests that, instead, a unitary Page curve can be recovered by adding disorder-averaged replica instantons to the path integral ...

Healthcare Technology Letters, 2019 This work investigates the application of zero-frequency resonator (ZFR) for detecting systolic peaks of photoplethysmogram (PPG) signals. Based on the authors’ studies, they propose an automated noise-robust method, which consists of the central ...

Royal Society Open Science, 2022 Dyslexic individuals have been reported to have reduced global motion sensitivity, which could be attributed to various causes including atypical magnocellular or dorsal stream function, impaired spatial integration, increased internal noise and/or ...

Average correlations vs. correlated averages [PDF]
Bulletin of the Psychonomic Society, 1983 When repeated-measures data are collected with small or even moderate sample sizes, correlation matrices show considerable variability. If one’s primary interest is in the correlations, some means of smoothing the coefficients may be desirable. Two methods of smoothing Pearson rs were investigated in the present study.

Word-embedding Based Text Vectorization Using Clustering
Моделирование и анализ информационных систем, 2021 It is known that in the tasks of natural language processing, the representation of texts by vectors of fixed length using word-embedding models makes sense in cases where the vectorized texts are short.The longer the texts being compared, the worse the ...

Annalen der Physik, 2015 We investigate in detail a recently introduced “coherent averaging scheme” in terms of its usefulness for achieving Heisenberg limited sensitivity in the measurement of different parameters. In the scheme, N quantum probes in a product state interact with a quantum bus.

A complete data processing workflow for CryoET and subtomogram averaging [PDF]
Nature Methods, 2019 Electron cryotomography is currently the only method capable of visualizing cells in three dimensions at nanometer resolutions. While modern instruments produce massive amounts of tomography data containing extremely rich structural information, data ...

Secondary Frequency and Voltage Control of Islanded Microgrids via Distributed Averaging [PDF]
IEEE transactions on industrial electronics (1982. Print), 2015 In this paper, we present new distributed controllers for secondary frequency and voltage control in islanded microgrids. Inspired by techniques from cooperative control, the proposed controllers use localized information and nearest-neighbor ...
