Complex-Valued Function Modeling of Bilateration and its Applications

IEEE Access, 2023
Bilateration is one of the localization methods that provides the location information of the target node using two anchors’ location information and two distances between the target node and each anchor.

Study of the Hypergeometric Equation via Data Driven Koopman-EDMD Theory

Axioms, 2023
We consider a data-driven method, which combines Koopman operator theory with Extended Dynamic Mode Decomposition. We apply this method to the hypergeometric equation which is the Fuchsian equation with three regular singular points.

First-order linear differential equations whose data are complex random variables: Probabilistic solution and stability analysis via densities

AIMS Mathematics, 2022
Random initial value problems to non-homogeneous first-order linear differential equations with complex coefficients are probabilistically solved by computing the first probability density of the solution.

Complex Correntropy with Variable Center: Definition, Properties, and Application to Adaptive Filtering

Entropy, 2020
The complex correntropy has been successfully applied to complex domain adaptive filtering, and the corresponding maximum complex correntropy criterion (MCCC) algorithm has been proved to be robust to non-Gaussian noises.

Ion-implantation-caused special damage profiles determined by spectroscopic ellipsometry in crystalline and in relaxed (annealed) amorphous silicon [PDF]

, 1993
We previously developed a fitting method of several parameters to evaluate ion-implantation-caused damage profiles from spectroscopic ellipsometry (SE) (M. Fried et al., J. Appl. Phys., 71 (1992) 2835).

Distributed dislocation-residual stress model of cold rolled strips based on the complex variable function method of plane elasticity

工程科学学报, 2016
In order to reveal the formation mechanism of the manifested waves of cold rolled strips,the distributed dislocation was calculated by using measured residual stress,and a distributed dislocation-residual stress model was proposed. The stress field of an
