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 ... -
The discovery of the expansion of the universe

Lemaître, and Edwin Hubble all contributed to the discovery of the expansion of the universe. If only two persons are ... -
Disentangling stochastic signals superposed with periodic oscillations
(Physics Letters A;Volume 384, Issue 15, 29 May 2020, 126307, Journal article; Peer reviewed, 2020-02-05)We introduce a procedure for separating periodic oscillations superposed on a stochastic signal. The procedure combines empirical mode decomposition (EMD) of a signal with tools of data analysis based on stochastic ... -
Distance Estimation Methods for Smartphone-Based Navigation Support Systems
(Lecture Notes in Networks and Systems;295, Conference object, 2021-08-03)Distance estimation is a key element of a navigation system. Various methods and instruments are used in distance estimation procedures. The methods and instruments used usually depend on the contexts of the application ... -
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
(Pattern Analysis and Applications;Published online 12 October 2019, Journal article; Peer reviewed, 2019-09-10)This paper proposes a novel classifier based on the theory of Learning Automata (LA), reckoned to as PolyLA. The essence of our scheme is to search for a separator in the feature space by imposing an LA-based random walk ... -
Distributed learning automata-based scheme for classification using novel pursuit scheme
(Applied intelligenc;volume 50, issue 7, Peer reviewed; Journal article, 2020-03-02)Learning Automata (LA) is a popular decision making mechanism to “determine the optimal action out of a set of allowable actions” (Agache and Oommen, IEEE Trans Syst Man Cybern-Part B Cybern 2002(6): 738–749, 2002). The ... -
DivergentNets: Medical Image Segmentation by Network Ensemble
(CEUR Workshop Proceedings;Vol-2886 - Proceedings of the 3rd International Workshop and Challenge on Computer Vision in Endoscopy (EndoCV 2021), Conference object, 2021)Detection of colon polyps has become a trending topic in the intersecting fields of machine learning and gastrointestinal endoscopy. The focus has mainly been on per-frame classification. More recently, polyp segmentation ... -
Do Code Smells Impact the Effort of Different Maintenance Programming Activities?
(Chapter; Peer reviewed; Chapter, 2016)Empirical studies have shown so far that code smells have relatively low impact over maintenance effort at file level. We surmise that previous studies have found low effects of code smells because the effort considered ... -
Do Norwegian academics who publish more earn higher salaries?
(Scientometrics;Volume 115, Issue 1, Journal article; Peer reviewed, 2018-01-21)Based on a sense of justice one may expect that productive academics with high publication outputs earn higher salaries than less productive academics. However, there is little evidence to support or reject such a belief. ... -
