  1. 1. Projective methods and longitudinal developmental research : considerations of data's nature and reliability

    Författare :Harald Janson; Bertil Mårdberg; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Longitudinal studies; projective methods; reliability; temporal stability; interrater agreement; epistemology; measurement; psykologi; Psychology;

    Sammanfattning : A projective method is viewed in the present work as a psychological test, by which is understood a standardized task that is set before a person, the solution of which is used for making inferences about psychological quantities. The present research was designed to shed light on several aspects of the usefulness of projective methods in longitudinal research, particularly with regard to reliability and to the distinction between measurement and theory-free empirical-comparison data.

  3. 2. Invariancy Methods for Points, Curves and Surfaces in Computational Vision

    Författare :Karl Åström; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; curved surface; space curve; planar curve; laser guided vehicles; AGV; autonomous guided vehicles; recognition; reconstruction; image sequence; multiple view geometry; affine; invariant; projective; Mathematics; Matematik;

    Sammanfattning : Many issues in computational vision can be understood from the interplay between camera geometry and the structure of images and objects. Typically, the image structure is available and the goal is to reconstruct object structure and camera geometry. This is often difficult due to the complex interdependence between these three entities. LÄS MER

  5. 4. Methods for vision-based robotic automation

    Författare :Fredrik Viksten; Linköpings universitet; []
    Nyckelord :VISATEC; robotic; camera; 2D technique; image sequences; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis presents work done within the EC-founded project VISATEC. Due to the different directions of the VISATEC project this thesis has a few different threads.A novel presentation scheme for medium level vision features applied to range sensor data and to image sequences.

  7. 5. Variational Methods for Moments of Solutions to Stochastic Differential Equations

    Författare :Kristin Kirchner; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Additive and multiplicative noise; Stochastic partial differential equation; Projective and injective tensor product space; Hilbert tensor product space; Space-time variational problem; Petrov-Galerkin discretization; Stochastic ordinary differential equation;

    Sammanfattning : Numerical methods for stochastic differential equations typically estimate moments of the solution from sampled paths. Instead, we pursue the approach proposed by A. Lang, S. Larsson, and Ch. LÄS MER
