Noise Cancellation with Static Mixtures of a Nonstationary Signal and Stationary Noise
EURASIP Journal on Advances in Signal Processing, 2003 We address the problem of cancelling a stationary noise component from its static mixtures with a nonstationary signal of interest. Two different approaches, both based on second-order statistics, are considered. The first is the blind source separation (

Mathematics, 2022 In this study, we look at the wavelet basis for the nonparametric estimation of density and regression functions for continuous functional stationary processes in Hilbert space. The mean integrated squared error for a small subset is established.

Prediction of fatal accidents in Indian factories based on ARIMA
Production Engineering Archives, 2018 The inherent benefits of an accident prevention program are generally known only after an accident has occurred. The purpose of implementation of the program is to minimize the number of accidents and cost of damages. Allocation of resources to implement

Wavelet Density and Regression Estimators for Functional Stationary and Ergodic Data: Discrete Time
Mathematics, 2022 The nonparametric estimation of density and regression function based on functional stationary processes using wavelet bases for Hilbert spaces of functions is investigated in this paper. The mean integrated square error over adapted decomposition spaces

Taking climate change into account: Non‐stationarity in climate drivers of ecological response
Journal of Ecology, 2020 Changes in the global climate system are creating increasingly non‐analogue climate conditions with expectations of non‐stationarity among climate drivers. Decoupling among climate drivers complicates the assessment of ecological response to the changing
