Digitalized story making in the classroom : a social semiotic perspective on gender, multimodality and learning
(Seminar.net : Media, technology and lifelong learning;3 (1), Academic article, 2007)The article takes the case of pupils in a fifth-year primary school class (10-11 years old) who use text and pictures in their creative writing on the classroom computers. The study confirms what the research ... -
The Dirac operator on compact quantum groups
(Journal für die reine und angewandte Mathematik;2010 (641), Journal article; Peer reviewed, 2010-01-20)For the q-deformation Gq, 0 < q < 1, of any simply connected simple compact Lie group G we construct an equivariant spectral triple which is an isospectral deformation of that defined by the Dirac operator D on G. Our ... -
Disaster Risk Reduction for All? Understanding Intersectionality in Disaster Situations
(IFIP Advances in Information and Communication Technology;Volume 622, Conference object, 2021-07-31)When designing digital services for citizens in a disaster situation, the diversity of its audience and their particular needs are not always sufficiently taken into account. Variables like digital equipment available, ... -
Discovering Fuzzy Association Rules from Patient's Daily Text Messages to Diagnose Melancholia
(Chapter; Peer reviewed, 2010)With the constant stress from work load and daily life people may show symptoms of melancholia. However, most people are reluctant to describe it or may not know that they already have it. In this paper a novel system ... -

Distinction between sequential and direct ionization in two-photon double ionization of helium
(Physical Review A. Atomic, Molecular, and Optical Physics;90, Journal article; Peer reviewed, 2014-11-10)This paper aims to shed some light on the role of the direct, or nonsequential, ionization channel in the regime in which the sequential channel is open in two-photon double ionization (TPDI) of helium. In this regime the ... -
Distributed Learning Automata-based S-learning scheme for classification
