Physics-informed neural networks for rarefied-gas dynamics: Thermal creep flow in the Bhatnagar–Gross–Krook approximation

The Physics of Fluids, 2021
This work aims at accurately solve a thermal creep flow in a plane channel problem, as a class of rarefied-gas dynamics problems, using Physics-Informed Neural Networks (PINNs).

Approximation of p-bounded variation functions by generalized de la Vallée Poussin means of negative order

Publications de l'Institut Mathématique (Beograd)
The rate of convergence of negative order generalized de la Vallee Poussin means of the Fourier series of a 2?-periodic function of p-bounded variation, is estimated.

Stable Approximation Algorithms for Dominating Set and Independent Set

International Workshop and International Workshop on Approximation, Randomization, and Combinatorial Optimization. Algorithms and Techniques
We study the Dominating set problem and Independent Set Problem for dynamic graphs in the vertex-arrival model. We say that a dynamic algorithm for one of these problems is $k$-stable when it makes at most $k$ changes to its output independent set or ...

New linear approximation method applied to crude operations scheduling

Jornadas de Automática
Este artículo aborda la optimización de la programación de las operaciones de crudo en una refinería abastecida por barcos. Un reto clave en este proceso es la gestión del almacenamiento de crudos en tanques. Dado que la capacidad de almacenamiento es

Simultaneous Diophantine approximation with a divisibility condition

Journal de Théorie des Nombres de Bordeaux
In a previous paper, we studied certain sequences of simultaneous rational approximations in ${\bf R}^2$ which present some analogy with the continued fractions. We got results around the Littlewood conjecture by using such approximations.
