Convergence of a spectral regularization of a time-reversed reaction-diffusion problem with high-order Sobolev-Gevrey smoothness
Vo Anh Khoa
The present paper analyzes a spectral regularization of a time-reversed reaction-diffusion problem with globally and locally Lipschitz nonlinearities. This type of inverse and ill-…
Convexification inversion method for nonlinear SAR imaging with experimentally collected data
M. V. Klibanov, V. A. Khoa, A. V. Smirnov +4
This paper is concerned with the study of a version of the globally convergent convexification method with direct application to synthetic aperture radar (SAR) imaging. Results of…
An inverse problem of a simultaneous reconstruction of the dielectric constant and conductivity from experimental backscattering data
Vo Anh Khoa, Grant W. Bidney, Michael V. Klibanov +4
This report extends our recent progress in tackling a challenging 3D inverse scattering problem governed by the Helmholtz equation. Our target application is to reconstruct dielect…
Convergence analysis of a variational quasi-reversibility approach for an inverse hyperbolic heat conduction problem
Vo Anh Khoa, Manh-Khang Dao
We study a time-reversed hyperbolic heat conduction problem based upon the Maxwell--Cattaneo model of non-Fourier heat law. This heat and mass diffusion problem is a hyperbolic typ…
Convexification for a 3D inverse scattering problem with the moving point source
Vo Anh Khoa, Michael Victor Klibanov, Loc Hoang Nguyen
For the first time, we develop in this paper the globally convergent convexification numerical method for a Coefficient Inverse Problem for the 3D Helmholtz equation for the case w…
Strong convergence of a linearization method for semi-linear elliptic equations with variable scaled production
Anh-Khoa Vo, Ekeoma Rowland Ijioma, Nhu-Ngoc Nguyen
This work is devoted to the development and analysis of a linearization algorithm for microscopic elliptic equations, with scaled degenerate production, posed in a perforated mediu…
An improved quasi-reversibility method for a terminal-boundary value multi-species model with white Gaussian noise
Nguyen Huy Tuan, Vo Anh Khoa, Phan Thi Khanh Van +1
Upon the recent development of the quasi-reversibility method for terminal value parabolic problems in \cite{Nguyen2019}, it is imperative to investigate the convergence analysis o…
Uniqueness result for an age-dependent reaction-diffusion problem
Vo Anh Khoa, Tran The Hung, Daniel Lesnic
This paper is concerned with an age-structured model in population dynamics. We investigate the uniqueness of solution for this type of nonlinear reaction-diffusion problem when th…
On a pore-scale stationary diffusion equation: scaling effects and correctors for the homogenization limit
Vo Anh Khoa, Thieu Thi Kim Thoa, Ekeoma Rowland Ijioma
In this paper, we consider a microscopic semilinear elliptic equation posed in periodically perforated domains and associated with the Fourier-type condition on internal micro-surf…
