Kurtosis in Large-Scale Structure as a Constraint on Non-Gaussian Initial Conditions [PDF]
, 1995 We calculate the kurtosis of a large-scale density field which has undergone weakly non-linear gravitational evolution from arbitrary non-Gaussian initial conditions.

Novel spectral kurtosis technology for adaptive vibration condition monitoring of multi-stage gearboxes [PDF]
, 2016 In this paper, the novel wavelet spectral kurtosis (WSK) technique is applied for the early diagnosis of gear tooth faults. Two variants of the wavelet spectral kurtosis technique, called variable resolution WSK and constant resolution WSK, are ...

Feature Map Activation Analysis for Object Key-Point Detection
IEEE Access, 2023 Determining object location information in an image can enable more accurate CNN classification. Several extended CNN models have been developed to include both object location and classification into a unified model, at a cost of increasing compute ...

A computer program for grain-size data [PDF]
, 1965 The computer program presented here seeks to improve estimation of statistical parameters for grain-size data by use of interpolated values. Interpolation is made by fitting a series of overlapping parabolas to the data, and follows the method of Snyder

Mastering the Body and Tail Shape of a Distribution
Mathematics, 2021 The normal distribution and its perturbation have left an immense mark on the statistical literature. Several generalized forms exist to model different skewness, kurtosis, and body shapes.

A Hybrid EMD-Kurtosis Method for Estimating Fetal Heart Rate from Continuous Doppler Signals
Frontiers in Physiology, 2017 Monitoring of fetal heart rate (FHR) is an important measure of fetal wellbeing during the months of pregnancy. Previous works on estimating FHR variability from Doppler ultrasound (DUS) signal mainly through autocorrelation analysis showed low accuracy ...
