  1. 1. Group work and physics : characteristics, learning possibilities and patterns of interaction

    Author : Maria Berge; Umeå universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; group work; engineering education; higher education; physics education; science education; multi-theoretic perspective; phenomenography; variation theory; positioning theory; conversation analysis;

    Abstract : This thesis explores group work in physics at university level. The guiding researchinterest is what happens in the students’ interactions during such (instructional)activities, focusing both on the physics content and group dynamics. READ MORE

  2. 2. Geometry and Critical Configurations of Multiple Views

    Author : Fredrik Kahl; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; algebra; algebraic geometry; field theory; Number Theory; Matematik; Mathematics; reconstruction; image sequence; absolute conic; critical motions; critical surfaces; perspective projection; affine geometry; Euclidean geometry; multiple view geometry; projective geometry; group theory; Talteori; fältteori; algebraisk geometri; gruppteori; Mathematical logic; set theory; combinatories; Matematisk logik; mängdlära; kombinatorik;

    Abstract : This thesis is concerned with one of the core problems in computer vision, namely to reconstruct a real world scene from several images of it. The interplay between the geometry of the scene, the cameras and the images is analyzed. READ MORE

  3. 3. Algorithmic Methods in Combinatorial Algebra

    Author : Anna Torstensson; Algebra; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; algebraic geometry; field theory; Number Theory; maximal symmetry group; resultant; SAGBI basis; Orthogonal decomposition; algebra; group theory; Talteori; fältteori; algebraisk geometri; gruppteori;

    Abstract : This thesis consists of a collection of articles all using and/or developing algorithmic methods for the investigation of different algebraic structures. Part A concerns orthogonal decompositions of simple Lie algebras. The main result of this part is that the symplectic Lie algebra C3 has no orthogonal decomposition of so called monomial type.

  4. 4. Restaurant meal experiences from customers' perspectives : a grounded theory approach

    Author : Kai Victor Hansen; Inga-Britt Gustafsson; Øystein Jensen; Tommy Andersson; Örebro universitet; []
    Keywords : Customers; meal; grounded theory; à la Carte restaurants; meal experience categories; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Culinary Arts and Meal Science; Måltidskunskap; Måltidskunskap; Culinary Arts and Meal Science;

    Abstract : The purpose of this doctoral dissertation has been to increase the knowledge of customers’ view on relation to commercial restaurant meals and thereby to increase the knowledge within the restaurant industry about customers’ perspectives about meals. The dissertation is based on four studies of customers’ meal experiences in á la Carte restaurants in Norway. READ MORE

  5. 5. Quasi-Lie Algebras and Quasi-Deformations. Algebraic Structures Associated with Twisted Derivations

    Author : Daniel Larsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Talteori; fältteori; algebraisk geometri; algebra; gruppteori; Lie Algebras; Quasi-Deformations; Number Theory; field theory; algebraic geometry; group theory; Quasi-Lie Algebras;

    Abstract : This thesis introduces a new deformation scheme for Lie algebras, which we refer to as ?quasi-deformations? to clearly distinguish it from the classical Grothendieck-Schlessinger and Gers-tenhaber deformation schemes. The main difference is that quasi-deformations are not in gene-ral category-preserving, i.e. READ MORE
