Optimal mesh design for the finite element approximation of reaction-diffusion problems
(2002)
We consider the numerical approximation of singularly perturbed problems, and in particular reactiondiffusion problems, by the h version of the finite element method. We present guidelines on how to design non-uniform ...
Robust adaptive control for a class of MIMO nonlinear systems with guaranteed error bounds
(2003)
The design of stabilizing controllers for multiple-input-multiple-output (MIMO) nonlinear plants with unknown nonlinearities is a challenging problem. The high dimensionality coupled with the inability to identify the ...
Robust adaptive control for a class of mimo nonlinear systems
(2002)
The design of stabilizing controllers for nonlinear plants with unknown nonlinearities is a challenging problem. The inability to identify the nonlinearities on-line or off-line accurately motivates the design of stabilizing ...
The singular function boundary integral method for Laplacian problems with boundary singularities in two and three-dimensions
(2010)
We present a Singular Function Boundary Integral Method (SFBIM) for solving elliptic problems with a boundary singularity. In this method the solution is approximated by the leading terms of the asymptotic solution expansion, ...
A singular function boundary integral method for laplacian problems with boundary singularities
(2006)
A singular function boundary integral method for Laplacian problems with boundary singularities is analyzed. In this method, the solution is approximated by the truncated asymptotic expansion for the solution near the ...
Finite element computations for the Reissner-Mindlin plate model
(1998)
We consider the finite element (FE) approximation of the Reissner - Mindlin (RM) plate model, and indicate how to design meshes that yield accurate results when the p/hp version of the standard FE method is used. These ...
A p-version MITC finite element method for Reissner-Mindlin plates with curved boundaries
(2006)
We consider the approximation of Reissner-Mindlin plates with curved boundaries, using a p-version MITC finite element method. We describe in detail the formulation and implementation of the method, and emphasize the need ...
A numerical study on the finite element solution of singularly perturbed systems of reaction-diffusion problems
(2007)
We consider the approximation of singularly perturbed systems of reaction-diffusion problems, with the finite element method. The solution to such problems contains boundary layers which overlap and interact, and the ...
Complex-valued tapers
(2005)
The spectral estimation method based on the average of short, tapered periodograms is re-examined. The bias of such estimators is typically O(1/b2), where b is the length of the short blocks. Much of the current researeh ...
