7. Zusammenfassung. Anliegen der Arbeit ist es, Volumen- und Oberflachenkomplexe zu vergleichen. Hierzu werden Befunde uber die Schwingungsspektren (uberwiegend IR-, aber auch Ramanspektren) sowie der Elektronenabsorptionsspektren zur Diskussion hera

The fuzzy symmetry concept developed by us for planar forms (using a Fourier analysis of the form's contour function R ( ϕ ), [1]) is applied to ensembles of points. We calculate misfit values Δ (inversely proportional to the degree of symmetry) fo

Fresh-water plants generate extraordinarily high electric potential differences at the plasma membrane. For a deeper understanding of the underlying transport processes a mathematical model of the electrogenic plasmalemma ion transport was developed

The geometric structure of isodiastemic manifolds (i.e., manifolds on which the equilaterality of polygons is preserved) within a form space Fα spanned by N − 2 consecutive vertex angles αi (internal coordinates) of plane N-gons, is reported for

Form variations are described in an appropriately constructed form space F (typically an R n ), where every point of F represents a different form. Regarding the symmetries of the forms, F can be divided into disjunct isosymmetric manifolds, i.e., po

A second approach to the evaluation of membership functions for a fuzzy form symmetry concept (Kohler, 1991) is described. Fuzzification of the symmetry requirements (only approximate identity or even complete non-identity instead of identity origina
