Semantisch-räumliche Strukturierung von Wissen - neue Qualitäten der kooperativen Wissenskonstruktion durch SVG
Aufgrund der hohen Dynamik kooperativer computergestützter Lernprozesse sollte eine Lernumgebung nicht nur Möglichkeiten zur Kommunikation, Koordination und Kooperation bereitstellen, sondern es ebenfalls gestatten, die gemeinsam erzeugten Wissensbereiche aufzubewahren. Der vorliegende Beitrag zeigt auf, wie mittels der SVG-Technologie die Persistenz einer kooperativ erzeugten Lernumgebung erzi...
متن کاملconstruction of vector fields with positive lyapunov exponents
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
15 صفحه اولDistinguished positive regular representations
Let $G$ be a tamely ramified reductive $p$-adic group. We study distinction of a class of irreducible admissible representations of $G$ by the group of fixed points $H$ of an involution of $G$. The representations correspond to $G$-conjugacy classes of pairs $(T,phi)$, where $T$ is a tamely ramified maximal torus of $G$ and $phi$ is a quasicharacter of $T$ whose restriction t...

متن کاملFrequency of false positive responses in patients with multiple positive reactions in patch test
Background and aim: Contact dermatitis is an inflammatory skin response due to contact with environmental materials manifested as acute or chronic eczema. Patch test is the standard test to recognize responsible allergen. The objective of this study was to evaluate the frequency of false positive patch test responses in patients with Exited Skin Syndrome (ESS).Materials...
