On the ill-posed problem for the Poisson equation
Қарағанды университетінің хабаршысы. Математика сериясы, 2018 A boundary value problem in a two - dimensional rectangular region for the Poisson equation is studied in the paper. The original ill - posed boundary value problem is transformed to the optimal control problem.

On rules for stopping the conjugate gradient type methods in ill‐posed problems
Mathematical Modelling and Analysis, 2007 We consider stopping rules in conjugate gradient type iteration methods for solving linear ill‐posed problems with noisy data. The noise level may be known exactly or approximately or be unknown. We propose several new stopping rules, mostly for the case

Redefining the Health Risk of Battery Materials Through a Biologically Transformed Metal Mixture
Advanced Science, EarlyView.Inhaled NCM particles undergo lysosomal degradation, releasing complex ion mixtures that induce systemic impact. The impact is determined by a critical balance between antagonistic Ni‐Co interactions and synergistic Mn effects. To capture these complexities in risk assessment, we develop an IAI model, ensuring a more accurate quantitative risk ...

Conformal Reconfigurable Intelligent Surfaces: A Cylindrical Geometry Perspective
Advanced Electronic Materials, EarlyView.Cylindrical reconfigurable intelligent surfaces are explored for low‐complexity beam steering using one‐bit meta‐atoms. A multi‐level modeling approach, including optimization‐based synthesis, demonstrates that even minimal hardware can support directive scattering.

DETERMINATION OF SELECTED PARAMETERS IN A 1D OPEN CHANNEL FLOW MODEL
TASK Quarterly, 2007 Determination of the model’s parameters is an important stage of mathematical models’ application. In the case of a free-surface 1D unsteady flow model defined by the de Saint-Venant equations, one of the groups of parameters to be estimated is the set ...
