  2. 16. Mathematics teachers' conceptions about equations

    Author : Iiris Attorps; Högskolan i Gävle; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; algebra; conception; equation; learning; mathematics teacher; Subject didactics; Ämnesdidaktik; MATHEMATICS; MATEMATIK;

    Abstract : The aim of this study is to describe and to clarify the mathematics teachers’ subject matter and pedagogical content conceptions about equations. As the basis of these conceptions, the teachers’ experiences of the concept learning of equations from their own school time are described. READ MORE

  6. 19. Neutron Multiplicity Counting with the Analysis of Continuous Detector Signals

    Author : Lajos Nagy; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Kolmogorov equation; fissile material assay; nuclear safeguards; fission chamber; neutron multiplicity counting; master equation;

    Abstract : Neutron multiplicity counting is a non-destructive assay method for determining the mass of fissile materials (primarily plutonium) using the measured values of the singles, doubles and triples detection rates. Traditionally, the detection rates are obtained from the counting statistics of neutron detectors. READ MORE

  7. 20. Finite element procedures for virtual tribology

    Author : Bertil Nilsson; Göteborgs universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Tribology; Reynolds equation; Stokes equation; cavitation; FEM; adaptivity; variational inequality; penalty formulation; error estima- tion; residual; duality.;

    Abstract : The main purpose of this thesis is to use modern goal-oriented adap- tive finite element techniques in order to improve the numerical simulation of tribology. Two novel adaptive finite element methods for the Reynolds thin film model, and Stokes model including cavitation are presented and their different strategies are compared. READ MORE
