  2. 1. Extensions and Applications of Affine Shape

    Author : Rikard Berthilsson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Systems engineering; Matematik; Mathematics; density of shape; maximum likelihood; matching constraint; surface; curve; handwriting; recognition; affine shape; reconstruction; computer technology; Data- och systemvetenskap;

    Abstract : A central problem in computer vision is to reconstruct the three-dimensional structure of a scene from a set of two-dimensional images. Traditionally this is done by extracting a set of characteristic points in the scene and to compute a reconstruction of these points. READ MORE

  6. 4. Soil formation and soil moisture dynamics in agriculture fields in the Mekong Delta, Vietnam conceptual and numerical models

    Author : Pham van Quang; Per-Erik Jansson; KTH; []
    Keywords : climate; CoupModel; pressure head; GLUE; soil water; characteristic curve; tensiometer;

    Abstract : Previous studies of agricultural conditions in the Mekong Delta (MD) have identified soil compaction as an obstacle to sustainable production. A conceptual model for soil formation was presented to demonstrate the link between soil hydrology and plant response. READ MORE

  7. 5. Constructive Newton–Puiseux Theorem, Sheaf Model of the Separable Closure and Dynamic Evaluation

    Author : Bassel Mannaa; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Newton–Puiseux; Algebraic curve; Sheaf model; Dynamic evaluation; Algebraic number; Grothendieck topos; Grothendieck topos;

    Abstract : Computing the Puiseux expansions of a plane algebraic curve defined by an affine equation over an algebraically closed field is a an important algorithm in algebraic geometry. This is the so-called Newton–Puiseux Theorem. The termination of this algorithm, however, is usually justified by non-constructive means. READ MORE
