Estimating Failure Probability with Neural Operator Hybrid Approach

Mathematics, 2023
Evaluating failure probability for complex engineering systems is a computationally intensive task. While the Monte Carlo method is easy to implement, it converges slowly and, hence, requires numerous repeated simulations of a complex system to generate ...

Ground-based radar data processing based on pseudo-polar coordinate system

The Journal of Engineering, 2019
Ground-based radar can make high-precision and real-time monitoring of micro changes in the observation area. It has been actually applied in various industries such as land, open-pit mines, water conservancy dams, and highway bridges.

Gravitational Energy Loss and Binary Pulsars in the Scalar Ether-Theory of Gravitation

, 2003
Motivation is given for trying a theory of gravity with a preferred reference frame (``ether'' for short). One such theory is summarized, that is a scalar bimetric theory. Dynamics is governed by an extension of Newton's second law.

Hard Polarized Photon Emission in Single Crystals by High Energy Electrons for Planar Crystal Orientations

, 1999
The radiation emission spectra of polarized photons emitted from charge particle in single crystal are obtained in semiclassical theory in Baer-Katkov-Strakhovenko approximation for planar crystal orientation.

The mathematics of adversarial attacks in AI – why deep learning is unstable despite the existence of stable neural networks

European Journal of Applied Mathematics
The unprecedented success of deep learning (DL) makes it unchallenged when it comes to classification problems. However, it is well established that the current DL methodology produces universally unstable neural networks (NNs).

An Inhomogeneous Transference Principle and Diophantine Approximation

, 2008
In a landmark paper, D.Y. Kleinbock and G.A. Margulis established the fundamental Baker-Sprindzuk conjecture on homogeneous Diophantine approximation on manifolds. Subsequently, there has been dramatic progress in this area of research.
