  1. 1. Shape depiction using Local Light Alignment : Evaluating the shape enhancement capabilities of the Local Light Alignment technique at multiple scales

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

    Author : Edvard Ahlsén; [2023]
    Keywords : Shape depiction; Non-photorealistic rendering; Shading; Multiple scales; Formskildring; ickerealistisk rendering; skuggning; skalrymdsmetoder;

    Abstract : Local Light Alignment is a new shading based technique in the field of shape depiction, a field which concerns itself with techniques to represent and enhance the three-dimensional (3D) shape of objects in two-dimensional (2D) visual media. The main idea of Local Light Alignment is to locally adjust the incoming direction of light to create contrast in a way that enhances the perception of shape and surface detail. READ MORE

  3. 2. The Influence of Roughness on Electrical Properties of Single Rock Fractures

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yu Hou; [2023]
    Keywords : Single fracture; Roughness; Current; Electrical properties; Relative standard deviation; Numerical simulations; Enkelfraktur; Grovhet; Ström; Elektriska egenskaper; Relativ standardavvikelse; Numeriska simuleringar;

    Abstract : To investigate the relationship between the structural characteristics of rough single fracturesand the electrical properties of the rock. In this study, a series of physical models of roughand smooth single fractures were established using the finite element method and Ohm's lawto test the electrical conductivity. READ MORE

  4. 3. Quantum Transport in Topological Insulator Nanowires

    University essay from KTH/Fysik

    Author : Sergi Pradas Rodriguez; [2023]
    Keywords : quantum transport; topological insulators; nanowires; numerical analysis; Kwant; etc.; kvanttransport; topologiska isolatorer; nanotrådar; numerisk analys; Kvant; etc.;

    Abstract : Three-dimensional topological insulators are materials that have a bulk band gap like a traditional insulator, but which hold topologically protected conducting surface states. In this thesis we present a numerical analysis of the surface states of topological insulator nanowires in the tight-binding approximation. READ MORE

  5. 4. Simulations of the Tenuous Upper Atmospheres of Exoplanets

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Lucian Spitzner; [2023]
    Keywords : astronomy; astrophyics; exoplanets; transmission spectroscopy; magnetic fields; atmospheres; ions; Physics and Astronomy;

    Abstract : Over the last decade, the interest in research on extraterrestrial planets has expanded dramatically. With the number of confirmed exoplanets having increased tenfold over the last ten years, we now know that many different types of exoplanets exist. READ MORE

  6. 5. Energy Performance Simulations of a Scania Truck Cabin

    University essay from Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Author : Leo Verde; Niklas Axenholm Strömberg; [2020]
    Keywords : GT-SUITE; Scania; Truck; Energy; Simulation;

    Abstract : The vast majority of trucks in the European Union are reliant on fossil fuels as their primary mode of propulsion. In efforts to decarbonise the truck transport sector manufacturers are developing electrified trucks. READ MORE
