18. Theorietag "Automaten und Formale Sprachen" : Wettenberg-Launsbach bei Gießen 30. September - 2. Oktober 2008
(2008)Der Theorietag ist die Jahrestagung der Fachgruppe Automaten und Formale Sprachen der Gesellschaft für Informatik. Er wird seit 1991 von Mitgliedern der Fachgruppe an wechselnden Orten in Deutschland und Österreich ... -
A first-order representation of stable models
(1998)Turi (1991) introduced the important notion of a constrained atom: an atom with associated equality and disequality constraints on its arguments. A set of constrained atoms is a constrained interpretation. We investigate ... -
A kinetic Fokker-Planck algorithm for simulating multiscale gas flows
(2022)Numerical, aerodynamic analysis of spacecraft requires the modeling of rarefied hypersonic flows. Such flow regimes are usually dominated by broad shock waves and strong expansion flows. In such areas of the flow the gas ... -
An ab initio approach to spin transport in magnetic tunnel junctions with disorder
(2015)In this work we investigate the spin(-dependent) transport in FeCo/MgO/FeCo magnetic tunnel junctions (MTJ) using advanced ab initio methods. Here, a special focus lies on the impact of the disordered alloy leads with ... -
Ab initio description of lattice dynamics in oxide semiconductors
(2017)As non-toxic and sustainable materials the system of binary oxide semiconductors Cu2O, Cu4O3, and CuO is in the focus of current research, e.g., for solar-cell applications. The objective of this work is to analyse the ... -
Ab initio Description of Materials Properties: An Application to Thermoelectric and Raman Scattering Phenomena
(2019)The need of efficient and sustainable alternatives to raw materials for technological applications has driven an intense research effort in the field of materials science. The scientific strategies aim to replace or ... -
Ab initio description of transport in nanostructures including electron-phonon coupling
(2018)The ongoing trends toward miniaturization and exploitation of non-classical degrees of freedom severely challenge the available methods for the theoretical description of electronic devices, because in realistic situations ... -
Der Abschattungseffekt im nuklearen Photoabsorptionsquerschnitt
(2000)In dieser Arbeit wurde der Abschattungseffekt in nuklearen Reaktionen hochenergetischer Teilchen diskutiert, wobei der Schwerpunkt auf die Erklärung desNiederenergie-Einsatzes der Abschattung in nuklearer Photoabsorption ... -
Abschlussbericht zum eingesetzten digitalen Kartenmaterial
(2015)Im Rahmen des Projekts GeoBib ist eine annotierte und georeferenzierte Online-Bibliographie der frühen deutsch- und polnischsprachigen Holocaust- und Lagerliteratur (1933-49) entstanden. Die frühen Texte, die die Verbrechen ... -
Advanced group III-nitride nanowire heterostructures - self-assembly and position-controlled growth
(2017)Group III-nitride nanowires and nanowire heterostructures were grown by plasma-assisted molecular beam epitaxy. Structural characterization was carried out by electron microscopy and X-Ray diffraction analysis; the optical ...
