Data fusion of satellite imagery for generation of daily cloud free images at high resolution level
Natalya Ivanchuk, Peter Kogut, Petro Martyniuk
In this paper we discuss a new variational approach to the Date Fusion problem of multi-spectral satellite images from Sentinel-2 and MODIS that have been captured at different res…
On Boundary Exact Controllability of One-Dimensional Wave Equations with Weak and Strong Interior Degeneration
Peter I. Kogut, Olha P. Kupenko, Günter Leugering
In this paper we study exact boundary controllability for a linear wave equation with strong and weak interior degeneration of the coefficient in the principle part of the elliptic…
Optime L2-Control Problem In Coefficients For A Linea Elliptic Equation. II. Approximation Of Solutions And Optimality Conditions
Thierry Horsin, Peter Kogut, Olivier Wilk
In this paper we study we study a Dirichlet optimal control prob- lem associated with a linear elliptic equation the coefficients of which we take as controls in the class of integ…
Weak Optimal Controls in Coefficients for Linear Elliptic Problems
Giuseppe Buttazzo, Peter I. Kogut
In this paper we study an optimal control problem associated to a linear degenerate elliptic equation with mixed boundary conditions. The equations of this type can exhibit the Lav…
