Adaptive learning with artificial barriers yielding Nash equilibria in general games
(Peer reviewed; Journal article, 2003)Artificial barriers in Learning Automata (LA) is a powerful and yet under-explored concept although it was first pro- posed in the 1980s. Introducing artificial non-absorbing barriers makes the LA schemes resilient to ... -

Families of Artinian and one-dimensional algebras
(Journal of Algebra;311, Journal article; Peer reviewed, 2007)The purpose of this paper is to study families of Artinian or one dimensional quotients of a polynomial ring R with a special look to level algebras. Let GradAlg^H(R) be the scheme parametrizing graded quotients of R with ... -
Unobstructedness and dimension of families of codimension 3 ACM algebras
(Contemporary Mathematics;448, Journal article; Peer reviewed, 2007)The goal of this paper is to study irreducible families of codimension 3, Cohen-Macaulay quotients A of a polynomial ring R=k[x_0,x_1,...,x_n]; mainly, we study families of graded Cohen-Macaulay quotients A of codimension ... -
Unobstructedness and dimension of families of Gorenstein algebras
(Collectanea Mathematica; 58(2), Journal article; Peer reviewed, 2007)The goal of this paper is to develop tools to study maximal families of Gorenstein quotients A of a polynomial ring R. We prove a very general Theorem on deformations of the homogeneous coordinate ring of a scheme Proj A ... -
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 ... -
If I had a rich picture… : insights into the use of “soft” methodological tools to support the development of interprofessional education
(Journal of Interprofessional Care;22 (5), Journal article; Peer reviewed, 2008)This paper describes a methodological experiment that aimed to test a small number of tools borrowed from Soft Systems Methodology. Those tools were intended to support action research for a project in interprofessional ... -
Solution of the time-dependent Schrödinger equation using uniform complex scaling
(Journal article; Journal article; Peer reviewed, 2008)The formalism of complex rotation of the radial coordinate is studied in the context of time-dependent systems. The applicability of this method is discussed and illustrated with numerical examples involving atoms exposed ... -
The structure behind it all
(Journal article; Peer reviewed; Journal article, 2009)The talk discussed collisions where the structure of the systems involved plays a decisive role for the outcome of the event. For many types of charge changing processes the presence of resonant states can change the ... -
Ideals generated by submaximal minors
(Algebra & Number Theory;3 (4), Journal article; Peer reviewed, 2009)The goal of this paper is to study irreducible families W(b;a) of codimension 4, arithmetically Gorenstein schemes X of P^n defined by the submaximal minors of a t x t matrix A whose entries are homogeneous forms of degree ... -
Solution of the Dirac equation for hydrogenlike systems exposed to intense electromagnetic pulses
(Journal article; Peer reviewed, 2009)The time-dependent Dirac equation is solved numerically and compared to the corresponding prediction of the nonrelativistic Schrödinger equation for hydrogenlike systems exposed to intense laser pulses. It is found that ... -
Branded selves : how children in Norway relate to marketing on a social network site
(Journal of children and media;3 (3), Journal article; Peer reviewed, 2009-07-22)Theories of branding and self presentation inform an ethnographic study of how a group of classmates aged 11–12 construct identities by use of the brands and branded resources made available to them on the social network ... -
Online MCQ - formative or summative assessment? : experiences from a higher educational environment
(Chapter; Peer reviewed, 2010)Within the field of Higher Education there has been a growing interest in formative assessment. A range of online tools for multiple choice questions (MCQ) are often made available to academic staff, but the extent and ... -
Studies or Leisure? : a Cross-cultural Comparison of Taiwanese and Norwegian Engineering Students' Preferences for University Life
(International journal of engineering education;26 (1), Journal article; Peer reviewed, 2010)An insight into students' preferences and expectations of life at university is useful when trying to understand drop-out percentages and design study programs, especially in the global competition for students. This ... -
Visual Scoping of Private Information Displayed on Shared Tabletop Surfaces
(Chapter; Peer reviewed, 2010)Informations sharing in meetings or conference calls are often done by displaying the information on a shared display, e.g. a projected or shared display, or a shared surface as a table. The amount of information on the ... -
Prosjekt Ymer : grafikkprosessering på sky
(Norsk Informatikkonferanse;2010, Chapter; Peer reviewed, 2010)Skyteknologi er en teknologi som tilbyr et spekter av nye tjenester som er lite utprøvd på mange felt. Et av disse områdene er bruk av sky i forbindelse med grafikkprosessering. Vil det være mulig å få en renderfarm til ... -
