Two-scale homogenization of a stationary mean-field game
, 2019 In this paper, we characterize the asymptotic behavior of a first-order stationary mean-field game (MFG) with a logarithm coupling, a quadratic Hamiltonian, and a periodically oscillating potential.

Oscillation and Asymptotic Behavior of Second Order Difference Equations
Journal of Mathematical Analysis and Applications, 1993 For certain difference equations of the form \(\Delta(c_ n\Delta y_ n)+p_ ny^ k_{n+1}=0\) \((n\geq 0\), \(k\) a quotient of odd positive integers) conditions are obtained which are equivalent to the fact that all solutions are oscillatory. Moreover, certain conditions are derived under which all nonoscillatory solutions of the difference equation ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Current Tracking Adaptive Control of Brushless DC Motors
International Journal of Adaptive Control and Signal Processing, EarlyView.In this paper, the current tracking for Brushless Direct Current motors is approached considering uncertainty in the parameters of the motor's model. An adaptive control scheme to compensate electrical parameters uncertainty is proposed without requiring any knowledge of the mechanical parameters.

Perturbations of time optimal control problems for a class of abstract parabolic systems [PDF]
, 2015 In this work we study the asymptotic behavior of the solutions of a class of abstract parabolic time optimal control problems when the generators converge, in an appropriate sense, to a given strictly negative operator.

Advanced Functional Materials, EarlyView.This review explores functional and responsive materials for triboelectric nanogenerators (TENGs) in sustainable smart agriculture. It examines how particulate contamination and dirt affect charge transfer and efficiency. Environmental challenges and strategies to enhance durability and responsiveness are outlined, including active functional layers ...

Asymptotic behavior and oscillation of functional differential equations
Journal of Mathematical Analysis and Applications, 2006 The author is concerned with the comparison of the solutions of the linear autonomuous functional differential equation \[ x'(t)= Lx_t\tag{*} \] and the perturbed equation \[ x'(t)= Lx_t+ f(t, x_t),\text{ where }f: [\sigma_0,\infty)\times \mathbb{C}\to \mathbb{C}^n\tag{**} \] is a continuous function and \(x_t\) is defined by \(x_t(s)= x(t+ s)\) for \(-
