Mixing material modes

open access: yesSPIE Proceedings, 2012
We present a novel setup in which real objects made of different materials can be mixed optically. For the materials we chose mutually very different materials, which we assume to represent canonical modes. The appearance of 3D objects consisting of any material can be described as linear superposition of 3D objects of different canonical materials, as

Simulating microstructure evolution during passive mixing [PDF]

open access: yes, 2011
The prediction of microstructure evolution during passive mixing is of major interest in order to qualify and quantify mixing devices as well as to predict the final morphology of the resulting blend.

Empirical Mode Decomposition Aided by Adaptive Low Pass Filtering [PDF]

open access: yes, 2012
Empirical Mode Decomposition (EMD) is an adaptive signal analysis technique which derives its basis functions from the signal itself. EMD is realized through successive iterations of a sifting process requiring local mean computation.

EMD Mode Mixing Separation of Signals with Close Spectral Proximity in Smart Grids [PDF]

open access: yes, 2018
The Empirical Mode Decomposition (EMD) is a signal analysis method that separates multi-component signals into single oscillatory modes called intrinsic mode functions (IMFs).

EEMD Independent Extraction for Mixing Features of Rotating Machinery Reconstructed in Phase Space

open access: yesSensors, 2015
Empirical Mode Decomposition (EMD), due to its adaptive decomposition property for the non-linear and non-stationary signals, has been widely used in vibration analyses for rotating machinery.

Global and Koopman modes analysis of sound generation in mixing layers [PDF]

open access: yes, 2013
It is now well established that linear and nonlinear instability waves play a significant role in the noise generation process for a wide variety of shear flows such as jets or mixing layers.

Estimation of Heart Rate and Respiratory Rate from PPG Signal Using Complementary Ensemble Empirical Mode Decomposition with both Independent Component Analysis and Non-Negative Matrix Factorization

open access: yesSensors, 2020
This paper proposes a framework combining the complementary ensemble empirical mode decomposition with both the independent component analysis and the non-negative matrix factorization for estimating both the heart rate and the respiratory rate from the ...
