Sector operator inequalities involving positive linear maps
Journal of Inequalities and ApplicationsIn this note, we prove the pth power ( p ≥ 2 $p\geq 2$ ) of two new sector operator inequalities for positive linear maps which are due to Bedrani et al. (Positivity 25:1601-1629, 2021) and Nasiri (Filomat 38:3429-3438, 2024), respectively.

Analytic Normalized Solutions of 2D Fractional Saint-Venant Equations of a Complex Variable
Journal of Function Spaces, 2021 Saint-Venant equations describe the flow below a pressure surface in a fluid. We aim to generalize this class of equations using fractional calculus of a complex variable.

Lyapunov-type Inequalities for Partial Differential Equations [PDF]
, 2013 In this work we present a Lyapunov inequality for linear and quasilinear elliptic differential operators in $N-$dimensional domains $\Omega$. We also consider singular and degenerate elliptic problems with $A_p$ coefficients involving the $p-$Laplace ...

The Furuta Inequality and an Operator Equation for Linear Operators
Publications of the Research Institute for Mathematical Sciences, 1999 We show that a special form of the Futura inequality is equivalent to an operator equation H^{\frac{p-2rn}{2(n+1)}} T (H^{\frac{p+2r}{n_+1}} T)^n H^{\frac{p-2_rn}{2(n+1)}} = K^p .

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.

Numerical sensitivity of Linear Matrix Inequalities for shorter sampling periods [PDF]
, 2012 The numerical sensitivity of Linear Matrix Inequalities (LMIs) arising in the H∞ norm computation in discrete time is analyzed. Rapid sampling scenarios are examined comparing both shift and delta operator formulations of the equations.

A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...
