A priori and a posteriori error analyses of an HDG method for the Brinkman problem
(Elsevier, 2018-01-15)
In this paper we introduce and analyze a hybridizable discontinuous Galerkin (HDG) method for the linear Brinkman model of porous media flow in two and three dimensions and with non-homogeneous Dirichlet boundary conditions. ...
MINRES for Second-Order PDEs with Singular Data
(2022)
Minimum residual methods such as the least-squares finite element method (FEM) or the discontinuous Petrov-Galerkin (DPG) method with optimal test functions usually exclude singular data, e.g., non-square-integrable loads. ...
On the convergence of successive Galerkin approximation for nonlinear output feedback H(infinity) control
(SPRINGER, 2010)
Although the formulation of the nonlinear theory of H(infinity) control has been well developed, solving the Hamilton-Jacobi-Isaacs equation remains a challenge and is the major bottleneck for practical application of the ...
An Efficient Galerkin BEM to Compute High Acoustic Eigenfrequencies
(ASME-AMER SOC MECHANICAL ENG, 2009)
An efficient numerical method, using integral equations, is developed to calculate precisely the acoustic eigenfrequencies and their associated eigenvectors, located in a given high frequency interval. It is currently known ...
An unfitted hybridizable discontinuous galerkin method in shape optimization.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Ingeniería Matemática., 2022)
Shape optimization seeks to optimize the shape of a region where certain partial differential
equation is posed such that a functional of its solution is minimized/maximized. In this thesis we
give an introduction to ...
Recent Advances in Least-Squares and Discontinuous Petrov-Galerkin Finite Element Methods
(De Gruyter, 2019)
© 2019 Walter de Gruyter GmbH, Berlin/Boston 2019.Least-squares (LS) and discontinuous Petrov-Galerkin (DPG) finite element methods are an emerging methodology in the computational partial differential equations with ...
Wavelet-galerkin method for computations of electromagnetic fields-computation of connection coefficients

Bending of stochastic Kirchhoff plates on Winkler foundations via the Galerkin method and the Askey-Wiener scheme
(ELSEVIER SCI LTD, 2010)
In this paper, the method of Galerkin and the Askey-Wiener scheme are used to obtain approximate solutions to the stochastic displacement response of Kirchhoff plates with uncertain parameters. Theoretical and numerical ...
