  1. 1. Topological Band Theory, An Overview

    University essay from Göteborgs universitet / Institutionen för fysik

    Author : Jens Roderus; [2021-06-14]
    Keywords : ;

    Abstract : Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explainedby standard quantum mechanics, but require also the framework of topology to be properly characterized.

  2. 2. Real-Time Plastic Deformation of Car Bodyworks

    University essay from Göteborgs universitet/Institutionen för data- och informationsteknik

    Author : Tom Ille; [2021-03-09]
    Keywords : computer graphics; plastic deformation; position based deformation;

    Abstract : Realism in video games is furthered each year. Particularly in racing and drivinggames, visual realism in the deformation of cars play a larger and larger role for theimmersion in a virtual world. With the improvements of modern hardware, a newphysically based simulation approach for the deformation of object has emerged. READ MORE

  3. 3. Microstructural evolution of ice under simple shear deformation

    University essay from Göteborgs universitet/Institutionen för geovetenskaper

    Author : Carina Liebl; [2021-01-11]
    Keywords : ;

    Abstract : To investigate microstructure in ice deformed under simple shear conditions experimentswere performed with artificial polycrystalline ice and natural ice samples form Vatnajökullglacier in Iceland. A new deformation apparatus was tested and results from deformationwere compared to literature to validate the method. READ MORE

  4. 4. Scenario Dose Calculation for Robust Optimization in Proton Therapy Treatment Planning

    University essay from Lunds universitet/Matematik LTH

    Author : Johan Sundström; [2021]
    Keywords : cancer; radiation therapy; proton therapy; treatment planning; robust optimization; dose calculation algorithms; scenarios; patient setup; range error; organ motion; pencil beam scanning; computational efficiency; range-corrected dose-mapping; Mathematics and Statistics;

    Abstract : Robust optimization plays a vital role in proton therapy treatment planning. A monoenergetic beam of protons has a finite range and delivers most of its dose at some specific depth in the patient. This allows the design of treatments that mainly damage the tumor and not any surrounding tissue. READ MORE

  5. 5. Numerical modelling of lime-cementcolumns in the passive zone of excavations in soft clays

    University essay from KTH/Jord- och bergmekanik

    Author : Anaëlle Gilot; [2021]
    Keywords : Deep mixing; lime-cement columns; excavations; clay; finite element method; advanced constitutive model; Mélange profond; colonnes de chaux-ciment; excavations; argile; méthode des éléments finis; modèle constitutif avancé; Jordförstärkning med kalk-cement pelare; utgrävningar; lera; finita elementmetoden; avancerad konstitutiv modell;

    Abstract : Excavations in soft clays come with a number of specific challenges. The use of lime-cement columns in the passive zone of such works represents a promising solution to some of these problems, such as basal heave stability or excessive deformations. READ MORE
