Variational Wavelet Ensemble Empirical (VWEE) Denoising Method for Electromagnetic Ultrasonic Signal in High-Temperature Environment with Low-Voltage Excitation

open access: yesChinese Journal of Mechanical Engineering, 2022
Low excitation voltage for an electromagnetic acoustic transducer (EMAT) is necessary for the petrochemical equipment and facilities inspection, which work at high-temperatures, to avoid potential explosion.

Multilevel ensemble Kalman filtering for spatio-temporal processes

open access: yes, 2020
We design and analyse the performance of a multilevel ensemble Kalman filter method (MLEnKF) for filtering settings where the underlying state-space model is an infinite-dimensional spatio-temporal process.

Application of Ensemble Empirical Mode Decomposition based Support Vector Regression Model for Wind Power Prediction

open access: yesJurnal Teknik Industri, 2020
Improving accuracy of wind power prediction is important to maintain power system stability. However, wind power prediction is difficult due to randomness and high volatility characteristics.

A decomposition clustering ensemble learning approach for forecasting foreign exchange rates

open access: yesJournal of Management Science and Engineering, 2019
A decomposition clustering ensemble (DCE) learning approach is proposed for forecasting foreign exchange rates by integrating the variational mode decomposition (VMD), the self-organizing map (SOM) network, and the kernel extreme learning machine (KELM).

Using Empirical Mode Decomposition to Study Periodicity and Trends in Extreme Precipitation [PDF]

open access: yes, 2015
Classically, we look at annual maximum precipitation series from the perspective of extreme value statistics, which provides a useful statistical distribution, but does not allow much flexibility in the context of climate change.

Symplectic Model Reduction of Hamiltonian Systems [PDF]

open access: yes, 2015
In this paper, a symplectic model reduction technique, proper symplectic decomposition (PSD) with symplectic Galerkin projection, is proposed to save the computational cost for the simplification of large-scale Hamiltonian systems while preserving the ...

Quantification of Dynamic Properties of Pile Using Ensemble Empirical Mode Decomposition

open access: yesAdvances in Civil Engineering, 2018
This paper investigated dynamical interactions between pile and frozen ground by using the ensemble empirical mode decomposition (EEMD) method. Unlike the conventional empirical mode decomposition (EMD) method, EEMD is found to be able to separate the ...

Ensemble empirical mode decomposition for tree-ring climate reconstructions

open access: yesTheoretical and Applied Climatology, 2011
A novel data adaptive method named ensemble empirical mode decomposition (EEMD) was used to reconstruct past temperature and precipitation variability in two 2,328- and 1,837-year tree-ring chronologies from the Dulan region, northeastern Qinghai–Tibetan Plateau.

Data-Driven Forecasting of High-Dimensional Chaotic Systems with Long Short-Term Memory Networks

open access: yes, 2018
We introduce a data-driven forecasting method for high-dimensional chaotic systems using long short-term memory (LSTM) recurrent neural networks. The proposed LSTM neural networks perform inference of high-dimensional dynamical systems in their reduced ...
