  1. 11. An approach of using Delaunay refinement to mesh continuous height fields

    University essay from KTH/Skolan för datavetenskap och kommunikation (CSC)

    Author : Noah Tell; Anton Thun; [2017]
    Keywords : Delaunay; height field; height map; chunks; procedural terrain generation; topological surface;

    Abstract : Delaunay refinement is a mesh triangulation method with the goal of generating well-shaped triangles to obtain a valid Delaunay triangulation. In this thesis, an approach of using this method for meshing continuous height field terrains is presented using Perlin noise as the height field. READ MORE

  3. 12. Case Studies on Fractal and Topological Analyses of Geographic Features Regarding Scale Issues

    University essay from Högskolan i Gävle/Samhällsbyggnad, GIS

    Author : Zheng Ren; [2017]
    Keywords : scale; fractal geometry; big data; topological analyses;

    Abstract : Scale is an essential notion in geography and geographic information science (GIScience). However, the complex concepts of scale and traditional Euclidean geometric thinking have created tremendous confusion and uncertainty. READ MORE

  4. 13. Localization Techniques, Yang-Mills Theory and Strings

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Linnea Svensk; [2016]
    Keywords : ;

    Abstract : Equivariant localization techniques exploit symmetries of systems, represented by group actions on manifolds, and use them to evaluate certain partition functions exactly. In this master thesis we begin with the study of localization in finite dimensions. READ MORE

  5. 14. Algorithmic Construction of Fundamental Polygons for Certain Fuchsian Groups

    University essay from Linköpings universitet/Matematik och tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : David Larsson; [2015]
    Keywords : Compact Riemann surfaces and uniformization; Fuchsian groups and automorphic functions; Hyperbolic geometry; Topological groups; Permutation groups; Computational methods; Covering spaces; branched coverings; Generators; relations; and presentations;

    Abstract : The work of mathematical giants, such as Lobachevsky, Gauss, Riemann, Klein and Poincaré, to name a few, lies at the foundation of the study of the highly structured Riemann surfaces, which allow definition of holomorphic maps, corresponding to analytic maps in the theory of complex analysis. A topological result of Poincaré states that every path-connected Riemann surface can be realised by a construction of identifying congruent points in the complex plane, the Riemann sphere or the hyperbolic plane; just three simply connected surfaces that cover the underlying Riemann surface.

  6. 15. Recognition of Surfaces Based on Haptic Information

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Tomohiro Nakano; [2015]
    Keywords : Technology and Engineering;

    Abstract : The main topic and focus in this thesis are surface recognition. In the sensing part, the surface information is collected as feature values. There are research approaches which focus on sensing surface tactile information by using sensors with robots. However, there are some disadvantages of using sensors. READ MORE
