The frame set of a function g ∈ L 2 (R) is the subset of all parameters (a, b) ∈ R 2+ for which the time-frequency shifts of g along aZ × bZ form a Gabor frame for L 2 (R). In
this paper, we investigate the frame set of a class of compactly supporte [...]

The observer construction has a main importance in the control theory and its applications for the systems of infinite dimension. Even if
the system’ state has an infinite dimension, its estimation is given using
some physical measures of finite di [...]

In this work we develop an a posteriori error analysis of a non-
conforming mixed finite element method for the coupling of fluid
flow with a porous medium . The approach utilizes the same non-
conforming Crouzeix-Rav.iart element discretization o [...]

In this paper, we develop an a posteriori error analysis for the stationary Stokes-Darcy coupled problem approximated by
conforming the finite element method on isotropic meshes in R d , d ∈ f2, 3g. The approach utilizes a new robust stabilized full [...]

In this paper we develop a new a posteriori error analysis for the Monge-Ampère
equation approximated by conforming finite element method on isotropic meshes in R 2 . The
approach utilizes a slight variant of the mixed discretization proposed by Gé [...]

We analyze a strongly coupled mixed formulation of the problem defining the inter-
action between a free fluid and poroelastic structure. The free fluid is governed by
the Stokes equations, while the flow in the poroelastic medium is modeled using [...]

This paper presents an a posteriori error analysis for a coupled continuum pipe-
flow/Darcy model in Karst aquifers. We consider a unified anisotropic finite element
discretization (i.e. elements with very large aspect ratio). Our analysis covers t [...]

We consider in this paper, a new a posteriori residual type error estimators for
the Stokes-Darcy coupled problem analyzed in [1] on isotropic meshes. Our
analysis covers two-and three-dimensional domains, conforming discretizations
as well as dif [...]

This study deals with an optimal control problem subject to a stochas-
tic elliptic equation with Dirichlet boundary condition and in which the
state process is regular on a stochastic Hilbert space. We prove the ex-
istence and uniqueness of the [...]

This paper provides a method for an optimal and equitable schedule of public load shedding
on any time interval and any number of sectors. By combining dynamic programming and knapsack
techniques, the method gives a schedule that iterates over part [...]
