A null controllability problem with a finite number of constraints on the normal derivative for the semilinear heat equation

Electronic Journal of Qualitative Theory of Differential Equations, 2012
We consider the semilinear heat equation in a bounded domain of $\mathbb{R}^m$. We prove the null controllability of the system with a finite number of constraints on the normal derivative, when the control acts on a bounded subset of the domain.

H2 model order reduction of bilinear systems via linear matrix inequality approach

IET Control Theory & Applications, 2023
This paper proposes an H2‐optimal model order reduction (MOR) method for bilinear systems based on the linear matrix inequality (LMI) approach. In this method, to reduce the computational complexity, at first, a reduced middle‐order approximation of the ...

Li-Ion Battery Anode State of Charge Estimation and Degradation Monitoring Using Battery Casing via Unknown Input Observer

Energies, 2022
The anode state of charge (SOC) and degradation information pertaining to lithium-ion batteries (LIBs) is crucial for understanding battery degradation over time. This information about each cell in a battery pack can help prolong the battery pack’s life

Observational-interventional Bell inequalities

Physical Review A
Generalizations of Bell's theorem, particularly within quantum networks, are now being analyzed through the causal inference lens. However, the exploration of interventions, a central concept in causality theory, remains significantly unexplored.

A note on the necessity of filtering mechanism for polynomial observability of time-discrete wave equation

Karpatsʹkì Matematičnì Publìkacìï, 2017
The problem of uniform polynomial observability was recently analyzed. It is shown that, when the continuous model is uniformly polynomially observable, it is sufficient to filter initial data to derive uniform polynomial observability inequalities for ...

Efficient Polarization‐Entangled Photon‐Pair Generation by a Fiber‐In‐Line van der Waals Material

Advanced Science, EarlyView.
Telecom‐wavelength polarization‐entangled photon pairs are generated in a van der Waals‐material‐integrated all‐fiber device via spontaneous parametric down‐conversion. The demonstrated fiberized quantum light source bridges emerging 2D nonlinear materials and practical quantum photonic systems, opening new opportunities for scalable fiber‐based ...

Observability inequality for the spatial discretization of weakly coupled 2d-wave equations

Demonstratio Mathematica
This study addresses the problem of indirect boundary observability for a spatial semi-discretization of weakly coupled two-dimensional wave equations. The discretization is performed using a finite difference method on a uniform mesh. More specifically,

Why Didn't I Get a Payout? Understanding Farmer Choices, Index Insurance, and Basis Risk

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Index insurance, while heralded as a potential solution to alleviate poverty and food insecurity among agricultural households, has its own set of challenges, notably basis risk. Basis risk is the discrepancy between the insurance payout and losses incurred, posing a significant deterrent to the adoption of index insurance.

Observability Estimate for the Fractional Order Parabolic Equations on Measurable Sets

Abstract and Applied Analysis, 2014
We establish an observability estimate for the fractional order parabolic equations evolved in a bounded domain Ω of ℝn. The observation region is F×ω, where ω and F are measurable subsets of Ω and (0,T), respectively, with positive measure.
