  1. 1. Abstract interpretations and abstract machines : contributions to a methodology for the implementation of logic programs

    Author : Ulf Nilsson; Jan Maluszynski; Samya Debray; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Computer science; Datavetenskap;

    Abstract : Because of the conceptual gap between high-level logic programming languages and existing hardware, the problem of compilation is hard. This thesis addresses two ways of narrowing this gap – program analysis through abstract interpretation and the introduction of intermediate languages and abstract machines. READ MORE

  2. 2. Geometric Models of Similarity

    Author : Mikael Johannesson; Kognitionsvetenskap; []
    Keywords : HUMANIORA; HUMANITIES; symmetry; similarity; separable dimensions; prominence; multidimensional scaling; Minkowski metric; machine learning; integral dimensions; familiarity; geometric models; distance metric; asymmetry; conceptual spaces; Computer science; numerical analysis; systems; control; Datalogi; numerisk analys; system; kontroll; Geometry; algebraic topology; Geometri; algebraisk topologi;

    Abstract : This dissertation examines and discusses some phenomena related to the geometric representation of similarity. It takes its inspiration from the existing body of empirical research within the fields of perceptual and cognitive psychology, but also connects to certain areas of machine learning. READ MORE

  3. 3. Models in chemistry education : A study of teaching and learning acids and bases in Swedish upper secondary schools

    Author : Michal Drechsler; Jan van Driel; Helge Strömdahl; Ingo Eilks; Karlstads universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Chemistry Education; Chemistry; Kemi; Chemistry; Kemi;

    Abstract : This thesis reports an investigation of how acid-base models are taught and understood in Swedish upper secondary school. The definition of the concepts of acids and bases has evolved from a phenomenological level to an abstract (particle) level. Several models of acids and bases are introduced in Swedish secondary school. READ MORE

    Abstract : This thesis consists of five essays exploring the validity of some extensively used financial models with a focus on the Swedish equity and derivative markets. The essays are of both an empirical and a theoretical nature. READ MORE

  5. 5. Multiparton Interaction Models and Parton Shower Studies

    Author : Richard Corke; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Multiparton Interactions; Parton Showers; Phenomenological Models; QCD Phenomenology;

    Abstract : This thesis involves phenomenological models for describing high energy particle collisions. One class of these models, multiparton interactions (MPI), deals with the fact that when colliding two hadrons, it is possible for more than one pair of their constituents to interact. READ MORE
