Signal Source Localization with Long-Term Observations in Distributed Angle-Only Sensors
Sensors, 2022 Angle-only sensors cannot provide range information of targets and in order to determine accurate position of a signal source, one can connect distributed passive sensors with communication links and implement a fusion algorithm to estimate target ...

Application of moving kriging interpolation based on the meshless local Petrov-Galerkin (MK-MLPG) method for the two-dimensional time-dependent Schrodinger equation [PDF]
Journal of Mahani Mathematical Research, 2018 In this article, an efficient numerical technique for solving the two-dimensional time-dependent Schrodinger equation is presented. At first, we employ the meshlesslocal Petrov-Galerkin (MLPG) method based on a local weak formulation to ...

A Parameter-Free Linear Sampling Method
IEEE Access, 2019 An inverse electromagnetic scattering problem is to determine the support of a scatterer from the scattered field or its far-field pattern. Characterized by ill-posedness and nonlinearity, the solution to this problem has difficulty in numerical ...

Application of Moving Kriging Shape Functions on Plate Problems
NUST Journal of Engineering Sciences, 2008 The Moving Kriging (MK) interpolation was recently proposed as a superior substitution of the Moving Least Square (MLS) approximation in the construction of shape functions for the Element-Free Galerkin Method (EFGM).

Adaptive Filtering for Full-Duplex UWA Systems With Time-Varying Self-Interference Channel
IEEE Access, 2020 To enable full-duplex (FD) in underwater acoustic (UWA) systems, a high level of self-interference cancellation (SIC) is required. This can be achieved by using a combination of SIC methods, including digital SIC.
