Abstract: We introduce a procedure to obtain both the automatic positioning of an initial contour for edge extraction and a new approach to skeletonize the captured contour. We propose a parametric ...

Physics Education Research, Faculty of Physics, University of Göttingen, Göttingen, Germany (RQ1) What impact do drawing activities have on students' conceptual understanding and their accuracy of ...

In the context of Lebesgue integration, we derive the divergence theorem for unbounded vector fields that can have singularities at every point of a compact set whose Minkowski content of codimension ...

We propose a new numerical approach for two-dimensional Maxwell's equations that is based on the Hodge decomposition for divergence-free vector fields. In this approach an approximate solution for ...

In this work, the divergence and curl operators are obtained using the coordinate free non rigid basis formulation of differential geometry. Although the authors have attempted to keep the ...
