A Universal PINNs Method for Solving Partial Differential Equations with a Point Source
International Joint Conference on Artificial Intelligence, 2022 In recent years, deep learning technology has been used to solve partial differential equations (PDEs), among which the physics-informed neural networks (PINNs)method emerges to be a promising method for solving both forward and inverse PDE problems ...

Improved On-Orbit MTF Measurement Method Based on Point Source Arrays
Remote Sensing, 2023 The modulation transfer function (MTF) is a key characteristic used to assess the performance of optical remote sensing satellite sensors. MTF detection can directly measure a sensor’s two-dimensional (2D) point spread function (PSF); therefore, it has ...

Advance detection technology of three-point source DC method based on COMSOL
Meikuang Anquan, 2023 When the traditional single point power supply electrode DC advance detection technology is used to detect the long-distance anomaly, the signal gradually weakens and the accuracy greatly decreases with the increase of detection distance.

Proximal methods for point source localisation
Journal of Nonsmooth Analysis and Optimization, 2023 Point source localisation is generally modelled as a Lasso-type problem on measures. However, optimisation methods in non-Hilbert spaces, such as the space of Radon measures, are much less developed than in Hilbert spaces. Most numerical algorithms for point source localisation are based on the Frank-Wolfe conditional gradient method, for which ad hoc ...
