Data‐driven forecasting of ship motions in waves using machine learning and dynamic mode decomposition

International Journal of Adaptive Control and Signal Processing, EarlyView.
Summary Data‐driven forecasting of ship motions in waves is investigated through feedforward and recurrent neural networks as well as dynamic mode decomposition. The goal is to predict future ship motion variables based on past data collected on the field, using equation‐free approaches.

Infinitely many periodic solutions for some second-order differential systems with p(t)-Laplacian

Boundary Value Problems, 2011
In this article, we investigate the existence of infinitely many periodic solutions for some nonautonomous second-order differential systems with p(t)-Laplacian. Some multiplicity results are obtained using critical point theory.

A Q‐Learning Algorithm to Solve the Two‐Player Zero‐Sum Game Problem for Nonlinear Systems

International Journal of Adaptive Control and Signal Processing, Volume 39, Issue 3, Page 566-581, March 2025.
A Q‐learning algorithm to solve the two‐player zero‐sum game problem for nonlinear systems. ABSTRACT This paper deals with the two‐player zero‐sum game problem, which is a bounded L2$$ {L}_2 $$‐gain robust control problem. Finding an analytical solution to the complex Hamilton‐Jacobi‐Issacs (HJI) equation is a challenging task.

Towards a Morse theory on Banach spaces via ultrafunctions

Arab Journal of Mathematical Sciences, 2015
Morse Theory on Banach spaces would be a useful tool in nonlinear analysis but its development is hindered by many technical problems. In this paper we present an approach based on a new notion of generalized functions called “ultrafunctions” which ...

Optimized Cell‐Based Platform for Platelet‐Free Detection of Heparin‐Induced Thrombocytopenia Antibodies

Advanced Biology, EarlyView.
This study optimized a cell‐based ELISA for HIT antibody detection using PF4‐coated breast cancer cells (MDA‐MB‐231). Enhanced binding was observed at 50 mM NaCl and 4% paraformaldehyde fixation. Live MDA‐MB‐231 and HCT‐116 cells demontrated superior sensitivity and specificity, providing a promising platelet‐free alternative for clinical HIT diagnosis.

Supporting teacher dispositions towards translanguaging-for-learning in a Grade 9 mathematics classroom

Reading & Writing
Background: Our article argues that the role of translingual instruction in mathematics classrooms is under-recognised in South Africa, as policymakers, teacher educators, teachers, learners, and parents assume that mathematics is just about numbers and ...
