  1. 1. AI Trained to Predict Thresholds of 2D Ellipse Percolation Systems

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Nirav Surajlal; [2021]
    Keywords : Low-dimensional Nanomaterials; Percolation Threshold; Machine Learning; Regression; Two-dimensional Heterogeneous Ellipse System; Lågdimensionella nanomaterial; Perkolering Tröskel; Maskininlärning; Regression; Tvådimensionellt Heterogent Ellipssystem;

    Abstract : Percolation theory is a relevant area of research in Nanotechnology because of its wide applications in nanoelectronics based on thin films of nanoparticles and composites, amongst others. In nanotechnology, systems are often explored through modelling and simulations. READ MORE

  3. 2. eulerr: Area-Proportional Euler Diagrams with Ellipses

    University essay from Lunds universitet/Statistiska institutionen

    Author : Johan Larsson; [2018]
    Keywords : Euler diagrams; Venn diagrams; ellipses; R; computer graphics; area-proportional; software; Mathematics and Statistics;

    Abstract : Euler diagrams are common and intuitive visualizations for data involving sets and relationships thereof. Compared to Venn diagrams, Euler diagrams do not require all set relationships to be present and may therefore be area-proportional also with subset or disjoint relationships in the input. READ MORE

  4. 3. The Förstner Interest Point Operator Subwindow Localization on SIFT Keypoints

    University essay from Umeå universitet/Institutionen för fysik

    Author : Viktor Jakobsson; [2015]
    Keywords : Photogrammetry; Subwindow; Localization; SIFT;

    Abstract : This thesis suggests a modification to the popular Scale Invariant Feature Transform (SIFT) algorithm (Lowe, 2004) often used in photogrammetry and computer vision to find features in images for measurement. The SIFT algorithm works by first detecting points in images at different scales and sizes. READ MORE

  5. 4. A Digital Elevation Model of the Lövåsen Esker

    University essay from Institutionen för teknik och byggd miljö

    Author : Hedda Bring; [2007]
    Keywords : surveying; DEM; elevation model; mätning; DEM; höjdmodell;

    Abstract : The threats imposed by the ongoing climate change become successively more clear. In the municipality of Sandviken the possible rise in water level in the lake Storsjön might cause major problems. READ MORE
