Computer Applications in Engineering Education, Volume 34, Issue 5, September 2026.ABSTRACT Digital twins serve as virtual replicas of physical systems. They can be used as a tool for engineering education by revealing the underlying principles behind unit operations. The project aimed to integrate digital twins into university engineering lab courses, complementing traditional methods by bridging the gap between experimentation and ...

An exciting Approach to Theoretical Spectroscopy
Advanced Science, Volume 13, Issue 47, 24 August 2026.ABSTRACT Theoretical spectroscopy, and more generally, electronic‐structure theory, are powerful concepts for describing the complex many‐body interactions in materials. They cover methods from ground‐state properties to lattice excitations and light‐matter interaction, including time‐resolved variants.

Detecting When One Probe Vector is Enough for Preconditioned Log‐Determinant Approximation
Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.ABSTRACT We present randomized algorithms for estimating the log‐determinant of regularized symmetric positive semi‐definite matrices. The algorithms access the matrix only through matrix vector products, and are based on the introduction of a preconditioner and stochastic trace estimator.

Comparison of Doubling the Size of Image Algorithms
Моделирование и анализ информационных систем, 2016 In this paper the comparative analysis for quality of some interpolation non-adaptive methods of doubling the image size is carried out. We used the value of a mean square error for estimation accuracy (quality) approximation.

The Use of Restarted Krylov Methods for Large Sparse Least Squares Problems
Numerical Linear Algebra with Applications, Volume 33, Issue 4, August 2026.ABSTRACT The use of restarted Krylov methods for solving large sparse linear least squares problems suffers from certain inherited difficulties. One of them arises in ill‐conditioned problems, when part of the residual vector is spanned by singular vectors that correspond to small singular values.
