Polynomial decay of the energy of solutions of coupled wave equations with locally boundary fractional dissipation

In this paper, we investigate a system of coupled wave equations featuring boundary fractional damping applied to a portion of the domain. We first establish the well-posedness of the system, proving the existence and uniqueness of solutions through semi-

Generalized Task‐Driven Design of Soft Robots via Reduced‐Order Finite Element Method‐Based Surrogate Modeling

Advanced Intelligent Systems, EarlyView.
A unified, reusable modeling pipeline enables task‐driven design of soft robots across actuator families and task scenarios. High‐fidelity simulations are compressed into compact pseudo‐rigid‐body joint surrogates, while a design‐conditioned meta‐model generates new surrogates from geometry parameters without rerunning finite element method.

Differentiability, analyticity and optimal rates of decay for damped wave equations

Electronic Journal of Differential Equations, 2012
We give necessary and sufficient conditions on the damping term of a wave equation for the corresponding semigroup to be analytic. We characterize damped operators for which the corresponding semigroup is analytic, differentiable, or exponentially ...

Rational approximation of discrete data with asymptomatic behaviour

This thesis is concerned with the least-squares approximation of discrete data that appear to exhibit asymptotic behaviour. In particular, we consider using rational functions as they are able to display a number of types of asymptotic behaviour.

Driver Behavior Modeling with Subjective Risk‐Driven Inverse Reinforcement Learning

Advanced Intelligent Systems, EarlyView.
A subjective risk‐driven inverse reinforcement learning framework is proposed to model driver decision‐making. It infers drivers' risk perception and risk tolerance from driving data. A learnable risk threshold is used to regulate decisions, enabling interpretable and human‐like driving behavior decisions.

Exponential decay and regularity for SG-elliptic operators with polynomial coefficients

, 2006
We study the exponential decay and the regularity for solutions of elliptic partial differential equations $Pu=f$, globally defined in $\R^n.$ In particular, we consider linear operators with polynomial coefficients which are SG-elliptic at infinity.

Polarization‐Dependent Calibration of Nitrogen‐Vacancy Axes for Precise Three‐Dimensional Magnetic Field Vector Determination

Advanced Physics Research, EarlyView.
Using polarization‐controllable pump light as the measurement basis, we break the polarization symmetry of NV center fluorescence and build the correlation between polarization direction and NV axis orientation, achieving high‐precision optical calibration of NV axes.
