  1. 1. Methods for quantitative analysis of myocardial perfusion SPECT : validated with magnetic resonance imaging, phantom studies and expert readers

    Författare :Helen Fransson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Segmentation; Quantification; Spline; Image registration; Cardiac image analysis; Myocardial perfusion SPECT;

    Sammanfattning : In this thesis, methods for automated analysis of myocardial perfusion single photon emission computer tomography (myocardial perfusion SPECT, MPS) images have been successfully developed and evaluated. MPS images show the perfusion of the myocardium and are used for diagnosing patients with suspected ischemic heart disease. LÄS MER

  4. 3. Early Elementary School Interventions in Reading and Mathematics

    Författare :Hanna Lindström-Sandahl; Henrik Danielsson; Stefan Samuelsson; Åsa Elwér; Joakim Samuelsson; Karin Landerl; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intervention; Special education; Instruction; Reading; Mathematics; Randomized controlled study; Follow-up; Elementary school; Intervention; Specialpedagogik; Undervisning; Läsning; Matematik; Randomiserad kontrollerad studie; Uppföljning; Grundskola;

    Sammanfattning : Supplemental special education support in reading and mathematics is essential for some children who struggle to learn basic reading or mathematics skills in their first years of schooling. Previous research shows that supplemental phonics and early numeracy and arithmetic instruction help students at risk for reading or mathematics difficulties. LÄS MER

  5. 4. Lärande i matematik : Om resonemang och matematikuppgifters egenskaper

    Författare :Yvonne Liljekvist; Héctor Perez Prieto; Johan Lithner; Per Nilsson; Karlstads universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; imitative and creative reasoning; educational design research; Imitativa och kreativa resonemang; designforskning; Pedagogiskt arbete; Educational Work;

    Sammanfattning : Since mathematical tasks are central to the teaching of mathematics, it is crucial to extend our knowledge of the characteristic features of tasks that are conducive to student development of problem-solving and reasoning abilities as well as conceptual understanding. The aim of the dissertation is to investigate how different types of mathematical tasks affect student learning and choice of learning strategies.

  7. 5. Numerical algorithms for high dimensional integration with application to machine learning and molecular dynamics

    Författare :Aku Kammonen; Anders Szepessy; Markos Katsoulakis; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Numerical Analysis; Numerisk analys;

    Sammanfattning : This thesis contains results on high dimensional integration with two papers, paper I and paper II, presenting applications in machine learning and two papers, paper III and paper IV, presenting applications to molecular dynamics.In paper I we present algorithms based on a Metropolis test for training shallow neural networks with trigonometric activation functions.
