Neural network‐based offset‐free model predictive control for nonlinear systems
AIChE Journal, Volume 72, Issue 2, February 2026.Abstract This paper proposes an offset‐free model predictive control (MPC) framework for nonlinear systems modeled using neural network‐based nonlinear autoregressive models with exogenous inputs (NARX). To address plant‐model mismatch and ensure offset‐free tracking, the NARX model is augmented with an integrating disturbance model, resulting in an ...

Mathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1943-1956, February 2026.ABSTRACT The existence of one or two strictly positive solutions of Neumann boundary value problems is studied in this paper where the nonlinearities are L1$$ {L}^1 $$‐Carathéodory functions, so they are not necessarily continuous. Additional weaker and better conditions than those used in previous results are posted on the nonlinearities to obtain ...

A modified Hammerstein modeling by the differential evolution algorithm
Signal, Image and Video Processing, 2023 Abstract This paper focuses on the nonlinear system modeling based on using a modified Hammerstein system model. The proposed Hammerstein structure is composed of a bilinear neural network (BNN) and a recursive digital system in the cascaded form.

On the Wiener and Hammerstein Models for Power Amplifier Predistortion [PDF]
2005 Asia-Pacific Microwave Conference Proceedings, 2006 This paper presents a comparative study on the suitability of using Hammerstein or Wiener models to identify the power amplifier (PA) nonlinear behavior considering memory effects. This comparative takes into account the operational complexity regarding the identification process as well as their accuracy to follow the PA ...

Cognitive Science, Volume 50, Issue 2, February 2026.Abstract Mate value is theorized to be a key driver of romantic partner choice, yet the cognitive mechanism underlying romantic partner choice remains poorly understood. Here, we assess whether initial romantic partner choice can be predicted by a general‐purpose, computational cognitive model of value and choice.

Positive Fixed Points of Hammerstein Integral Operators with Degenerate Kernel
Учёные записки Казанского университета: Серия Физико-математические наукиPositive fixed points of the Hammerstein integral operators with a degenerate kernel in the space of continuous functions C [0, 1] were explored. The problem of determining the number of positive fixed points of the Hammerstein integral operator was ...

Asian Journal of Control, Volume 28, Issue 1, Page 34-45, January 2026.Abstract We study a nonlinear ψ−$$ \psi - $$ Hilfer fractional‐order delay integro‐differential equation ( ψ−$$ \psi - $$ Hilfer FrODIDE) that incorporates N−$$ N- $$ multiple variable time delays. Utilizing the ψ−$$ \psi - $$ Hilfer fractional derivative ( ψ−$$ \psi - $$ Hilfer‐FrD), we investigate the Ulam–Hyers––Rassias (U–H–R), semi‐Ulam–Hyers ...

Essential dietary fatty acids affect intraspecific competition in herbivorous zooplankton
Limnology and Oceanography, Volume 71, Issue 1, January 2026.Abstract The trophic transfer efficiency at the pelagic phytoplankton‐zooplankton interface is—among other factors—governed by the dietary availability of polyunsaturated fatty acids (PUFAs) to herbivorous zooplankton. As most zooplankton taxa cannot synthesize PUFAs de novo, the phytoplankton PUFA composition is crucial for the herbivores' fitness. As

Adaptive Multilevel Feature Fusion and Dynamic Model Updating for Robust Visual Object Tracking
Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.Object tracking remains a challenging task due to significant variations in the appearance of target objects caused by factors such as deformation, occlusion, and rapid movement. These variations often result in model drift and tracking failure, particularly in complex and dynamic environments.
