Inverse problems for general second order hyperbolic equations with time-dependent coefficients [PDF]

, 2017
We study the inverse problems for the second order hyperbolic equations of general form with time-dependent coefficients assuming that the boundary data are given on a part of the boundary.

Stabilization of a nonlinear Euler-Bernoulli viscoelastic beam subjected to a neutral delay [PDF]

Theoretical and Applied Mechanics
An approach is implemented in this article to analyze the decay rate of nonlinear beams according to the Euler–Bernoulli equation in the context of rheological viscoelastic damping deformations taking into account the neutral type delay.

Controls on boundary layer ventilation: Boundary layer processes and large-scale dynamics [PDF]

, 2010
Midlatitude cyclones are important contributors to boundary layer ventilation. However, it is uncertain how efficient such systems are at transporting pollutants out of the boundary layer, and variations between cyclones are unexplained. In this study 15

Adaptive Backstepping Boundary Control for a Class of Modified Burgers’ Equation

Fractal and Fractional, 2023
Burgers’ equation is used to describe wave phenomena in hydrodynamics and acoustics. It was derived originally as a prototype to provide analytic insight into the nature of turbulence and its modeling, and has found applications in the study of shock ...

Quantum Control at the Boundary

, 2019
We present a scheme for controlling the state of a quantum system by modifying the boundary conditions. This constitutes an infinite-dimensional control problem.

Optimal Boundary Control of Non-Isothermal Viscous Fluid Flow

Fluids, 2019
We study an optimal control problem for the mathematical model that describes steady non-isothermal creeping flows of an incompressible fluid through a locally Lipschitz bounded domain.

Multidimensional Borg-Levinson Theorem [PDF]

, 2004
We consider the inverse problem of the reconstruction of a Schr\"odinger operator on a unknown Riemannian manifold or a domain of Euclidean space. The data used is a part of the boundary $\Gamma$ and the eigenvalues corresponding to a set of impedances ...
