  1. 1. Topics in Combinatorial Algebraic Geometry

    Författare :Anders Lundman; Sandra Di Rocco; Giorgio Ottaviani; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Sammanfattning : This thesis consists of six papers in algebraic geometry –all of which have close connections to combinatorics. In Paper A we consider complete smooth toric embeddings X ↪ P^N such that for a fixed positive integer k the t-th osculating space at every point has maximal dimension if and only if t ≤ k. LÄS MER

  3. 2. Statistical Segmentation and Registration of Medical Ultrasound Data

    Författare :Mattias Hansson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Registration; Segmentation; Feature descriptor; Statistical image and signal processing; Medical ultrasound; Variational methods; Mixture model; Bayesian; Markov Chain Monte Carlo; Similarity measur;

    Sammanfattning : The interpretation of ultrasonic imagery is typically not straightforward and of quite subjective nature and therefore strongly dependent on the expertise of its users. Thus the development of algorithms which aid in the interpretation of ultrasonic data is a highly relevant topic. LÄS MER

  4. 3. Undervisning om växande geometriska mönster : En variationsteoretisk studie om hur lärare behandlar ett matematiskt innehåll på mellanstadiet

    Författare :Klara Kerekes; Joakim Samuelsson; Angelika Kullberg; Marcus Samuelsson; Anna Wernberg; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Matematikundervisning; dimension av variation; algebra; mönster; växande geometriska mönster; möjligt lärande; variationsteori; Geometriundervisning; Mellanstadiet; Sverige;

    Sammanfattning : Syftet med studien är att analysera och beskriva hur lärare behandlar innehållet när de undervisar om växande geometriska mönster. Lärares handlingar och undervisning, där vissa aspekter av undervisningsinnehållet fokuseras och andra lämnas ofokuserade, ses som potential för förändringar i elevers erfarande av det undervisade innehållet.

  5. 4. 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

  7. 5. Satistical Modelling Of CO2 Exchange Between Land And Atmosphere : Using Stochastic Optimisation And Gaussian Markov Random Fields

    Författare :Unn Dahlén; Spatio-Temporal Stochastic Modelling Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Gaussiska Markovfält; Stokastisk optimering; CO2-flöden; Spatial statistik; Stochastic Optimisation; Gaussian Markov Random Fields; Atmospheric inverse modelling; Spatial statistics; Computational statistics;

    Sammanfattning : This thesis focuses on the development and application of efficient mathematicaltools for estimating and modelling the exchange of carbon dioxide (CO2) between the Earth and its atmosphere; here referred to as the global CO2 surface flux.There are two main approaches for estimating the CO2 flux: Processed based(bottom-up) modelling and atmospheric inversion (top-down) modelling.
