Robust Reinforcement Learning Control Framework for a Quadrotor Unmanned Aerial Vehicle Using Critic Neural Network

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Quadrotor unmanned aerial vehicle control is critical to maintain flight safety and efficiency, especially when facing external disturbances and model uncertainties. This article presents a robust reinforcement learning control scheme to deal with these challenges.

Exact solution of the relationship between the eigenvalue discreteness and the behavior of eigenstates in Su–Schrieffer–Heeger lattices

New Journal of Physics
The interplay between eigenvalue discreteness and eigenstate localization is a fundamental characteristic of one-dimensional Su–Schrieffer–Heeger (SSH) lattices.

A novel iterative method to approximate structured singular values

, 2016
A novel method for approximating structured singular values (also known as mu-values) is proposed and investigated. These quantities constitute an important tool in the stability analysis of uncertain linear control systems as well as in structured ...

Perturbed fractional eigenvalue problems

Discrete & Continuous Dynamical Systems - A, 2017
Let \begin{document} $Ω\subset\mathbb{R}^N$ \end{document} ( \begin{document} $N≥2$ \end{document} ) be a bounded domain with Lipschitz boundary. For each \begin{document} $p∈(1,∞)$ \end{document} and \begin{document} $s∈ (0,1)$ \end{document} we denote by \begin{document} $(-Δ_p)^s$ \end{document} the fractional \begin{document ...

Integration of Cholesterol Oxidase‐Based Biosensors on a Smart Contact Lens for Wireless Cholesterol Monitoring from Tears

Advanced Intelligent Systems, EarlyView.
The combination of a parity‐time symmetry wireless technology with a cholesterol sensor integrated into a smart contact lens enables high‐sensitivity cholesterol sensing at low concentration. Cholesterol plays a critical role in physiological functions, but elevated levels increase the risk of cardiovascular disease.

Analysis of plant metabolomics data using identification‐free approaches

Applications in Plant Sciences, EarlyView.
Abstract Plant metabolomes are structurally diverse. One of the most popular techniques for sampling this diversity is liquid chromatography–mass spectrometry (LC‐MS), which typically detects thousands of peaks from single organ extracts, many representing true metabolites.

Application for a Novel Perturbation Expansion Method

Journal of Algorithms & Computational Technology, 2009
We formulate a coupled vibration problem between a structure and an acoustic field by FEM (finite element methods). The problem leads to a nonstandard eigenvalue problem.

Perturbation method for non-square Hamiltonians and its application to polynomial oscillators

, 2005
A remarkable extension of Rayleigh-Schroedinger perturbation method is found. Its (N+q) x (N+1) - dimensional Hamiltonians (as emerging, e.g., during quasi-exact constructions of bound states) are non-square matrices at q > 1.
