  1. 6. Grafisk och algebraisk representation : Gymnasieelevers förståelse av linjära funktioner

    Författare :Annika Pettersson; Igor Gachkov; Kerstin Pettersson; Lovisa Sumpter; Karlstads universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; mathematics education; linear function; graphic representation; scale; concept image; Matematik; Mathematics;

    Sammanfattning : This thesis concerns upper secondary students’ understanding of algebraic and graphic representation of linear functions. Components of the students’ concept images, so-called ‘concept elements’, were studied as a way to capture their understanding. LÄS MER

  3. 7. Titchmarsh-Weyl M-function asymptotics and some results in the inverse spectral theory for vector-valued Sturm-Liouville equations and a certain higher order ordinary differential equation

    Författare :Erik Andersson; Matematik (naturvetenskapliga fakulteten); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Functions; differential equations; Funktioner; differentialekvationer; Paley-Wiener.; The generalized Fourier transform; A certain higher order ordinary differential equation; Borg-Marchenko theorems; Vector-valued Sturm-Liouville equations; Inverse spectral theory; Titchmarsh-Weyl M-function asymptotics; Asymptotics of solutions; Spectral measure;

    Sammanfattning : This discourse is constituted by two separate reprots, where the first one offers an elementary deduction of the leading order term asymptotics for the Titchmarsh-Weyl M-function corresponding to a vector-valued Sturm-Liouville equation of the form -(PU')'+QU=zu, xin[0,b), with P^{-1},W,Q being hermitean with locally integrable entries; and under some additional conditions on P^{-1} and W. In the special case of P=W=I, we give some further asymptotic results for the same M-function. LÄS MER

  4. 8. Rate as the relation of changes in two quantities : A variation theory perspective of learning rate of change

    Författare :Per Håkansson; Robert Gunnarsson; Ulla Runesson Kempe; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; rate of change; slope; covariation; functions; mathematics teaching and learning; variation theory; learning study; förändringstakt; lutning; samvariation; funktioner; matematiklärande; variationsteori; learning study;

    Sammanfattning : This thesis comprises three original papers about learning rate of change in school mathematics. The overall aim of the thesis is to contribute with knowledge in this particular area of research. Within this aim, each of the original papers contribute with its own perspective. LÄS MER

  5. 9. Local Polynomial Regression with Application on Lidar Measurements

    Författare :Torgny Lindström; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik; differential equations; Funktioner; differentialekvationer; variance-function estimation.; spatial dependence; nonparametric; local polynomial regression; local bandwidth selection; lidar; heteroscedasticity; Bivariate estimation; differential absorption; Functions;

    Sammanfattning : This thesis deals with the problem of estimating a function or one of its derivatives from a set of measurements, mainly of a bivariate or spatial nature which is so common in environmental applications. In this work particular attention has been on the lidar (light detection and ranging) application which is a versatile technique for measurement of among other things atmospheric trace gases.

  7. 10. Paradoxer i välfärden : När anhöriga blir lösningen på demensomsorgens utmaningar

    Författare :Emme-Li Vingare; Ulla Melin Emilsson; Lottie Giertz; Marjaana Seppänen; Linnéuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; family caregivers; dementia care; welfare paradoxes; familisation; systems; functions; anhöriga; demensomsorg; välfärdsparadoxer; familisering; system; funktioner; Socialt arbete; Social Work;

    Sammanfattning : This thesis addresses dementia care in Sweden and the function family caregivers are given. The aim of the thesis is to analyse critically the system of municipal eldercare and the function of family caregivers in this system, and in various types of organisations. LÄS MER
