David A. Conner,

Tenho o prazer, como Editor da IEEE Transactions on Education, de dar as boasvindas a IEEE-RITA ao portofolio de edições da IEEE Education Society. Nos dois últimos anos, a IEEE Education Society tem vindo a reflectir como poderá dar benefícios adicionais aos seus membros através das suas publicações. Além de IEEE Transactions on Education (periódico do IEEE sobre investigação em educação), The...

Alternative representations of boundary integral operators corresponding to elliptic boundary value problems are developed as a starting point for numerical approximations as, e.g., Galerkin boundary elements including numerical quadrature and panel-clustering. These representations have the advantage that the integrands of the integral operators have a reduced singular behaviour allowing to ch...

We present a new discretization method for homogeneous convectiondiffusion-reaction boundary value problems in 3D that is a non-standard finite element method with PDE-harmonic shape functions on polyhedral elements. The element stiffness matrices are constructed by means of local boundary element techniques. Our method, which we refer to as a BEM-based FEM, can therefore be considered a local ...

Classical integral operators usually display invariance with respect to orthogonal transformations. If the domain of an operator equation is symmetric with respect to some orthogonal transformations, then appropriate discretiza-tions of the operator equation lead to system matrices which are equivariant with respect to a group of permutations. This property can be exploited to design eecient me...

We analyze adaptive mesh-refining algorithms in the frame of boundary element methods (BEM) and the coupling of finite elements and boundary elements (FEM-BEM). Adaptivity is driven by the two-level error estimator proposed by Ernst P. Stephan, Norbert Heuer, and coworkers in the frame of BEM and FEM-BEM or by the residual error estimator introduced by Birgit Faermann for BEM for weakly-singula...
