Non-autonomous approximations governed by the fractional powers of damped wave operators
Electronic Journal of Differential Equations, 2019 In this article we study non-autonomous approximations governed by the fractional powers of damped wave operators of order $\alpha \in (0,1)$ subject to Dirichlet boundary conditions in an $n$-dimensional bounded domain with smooth boundary.

Rate of Convergence in Bootstrap Approximations
The Annals of Probability, 1988 X\({}_ 1,X_ 2,..\). are iid random variables with zero mean and variance 1. Let C denote the collection \((X_ 1,...,X_ n)\), and let \((X_ 1^*,...,X_ n^*)\) be a collection drawn at random from C, by sampling with replacement. Define \[ \bar X=n^{- 1}\sum^{n}_{j=1}X_ j,\quad \bar X^*=n^{- 1}\sum^{n}_{j=1}X_ j^*,\quad {\hat \sigma}^ 2=n^{- 1}\sum^{n}_{j=

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 ...

International Journal of Adaptive Control and Signal Processing, EarlyView.This work introduces an adaptive human pilot model that captures pilot time‐delay effects in adaptive control systems. The model enables the prediction of pilot–controller interactions, facilitating safer integration and improved design of adaptive controllers for piloted applications.

High order approximation theory for Banach space valued functions
Journal of Numerical Analysis and Approximation Theory, 2017 Here we study quantitatively the high degree of approximation of sequences of linear operators acting on Banach space valued di§erentiable functions to the unit operator. These operators are bounded by real positive linear companion operators.

Advanced Engineering Materials, EarlyView.This study investigates laser shock peening for enhancing fatigue performance of riveted aerospace aluminum joints. A comparative approach with cold expansion combines fatigue testing and synchrotron X‐ray methods. Integrating mechanical testing with residual stress and strain characterization provides insights into how different treatments affect the ...
