For example, when given analogies to use in solving problems, people are typically fairly selective about choosing analogies that have genuine structural overlap with the target problem (Bassok & Holyoak, 1989; Holyoak & Koh, 1987; Novick & Holyoak, 1991; Novick & Tversky, 1987; Ross, 1987; Ross, Ryan,...

The Hellenistic and Alexandrian Influences on Johannes’ Kepler Work

We investigate the close relationships between the astronomical and scientific work of the famous great astronomer Johannes Kepler and the major scientific in general, and astronomical in particular, achievements that took place within the Hellenistic period and the Alexandrian epoch that followed immediately, that is from the Battle of Actium until the death of the scholar and polymath Hypatia...

JOHANNES KEPLER UNIVERSITY LINZ Institute of Computational Mathematics BEM-based Finite Element Tearing and Interconnecting Methods

We present efficient domain decomposition solvers for a class of non-standard finite element methods (FEM). These methods utilize PDE-harmonic trial functions in every element of a polyhedral mesh, and use boundary element techniques locally in order to assemble the finite element stiffness matrices. For these reasons, the terms BEMbased FEM or Trefftz-FEM are sometimes used in connection with ...
