  1. 1. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

    University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Author : Eduardo Garcia Cañas; [2022]
    Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

    Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

  3. 2. Evaluation of margins and plan robustness for proton therapy of unilateral tonsil cancer.

    University essay from Umeå universitet/Institutionen för fysik; Umeå universitet/Institutionen för strålningsvetenskaper

    Author : Josefine Grefve; [2021]
    Keywords : ;

    Abstract : During proton therapy both target volumes and healthy tissue, including organs at risk (OARs), receives radiation dose. Thus, radiotherapy is a trade-off between good target coverage and OAR sparing. For protons, most of the dose is deposited right before it is stopped, a phenomenon termed the Bragg peak. READ MORE

  4. 3. An Analysis of Markov Regime-Switching Models for Weather Derivative Pricing

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Fredrik Gerdin Börjesson; [2021]
    Keywords : Weather derivatives; temperature modeling; Markov switching models; Lévy processes; expectation-maximization algorithm; generalized hyperbolic distributions; Monte Carlo simulation;

    Abstract : The valuation of weather derivatives is greatly dependent on accurate modeling and forecasting of the underlying temperature indices. The complexity and uncertainty in such modeling has led to several temperature processes being developed for the Monte Carlo simulation of daily average temperatures. READ MORE

  5. 4. Design and Simulation of Terahertz Antenna for Spintronic Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : Nils Eivarsson; Malin Bohman; Emil Grosfilley; Axel Lundberg; [2020]
    Keywords : spintronics; terahertz; THz; antenna; simulation; COMSOL multiphysics;

    Abstract : Spintronics is a spin-electronic field where the electron spinangular momentum, in conjunction with charge, is used to read andwrite information in magnetic sensors and logic circuits, e.g. hard disk drive (HDD), magnetic random access memory (MRAM) and broadband TeraHertz (THz) emitters.

  6. 5. Flexural strength of zirconia after grinding, using diamond burrs, silicon carbide burr and water-cooling

    University essay from Malmö universitet/Odontologiska fakulteten (OD)

    Author : Markus Rosensvärd; David Danneker; [2019]
    Keywords : Zirconia; ytzp; grinding; zirconium; aging; Strength;

    Abstract : SyfteSyftet med föreliggande studie är att undersöka om slipning av zirkonia med silikatkarbid, diamant, vattenkylning, höghastighetsturbin och låghastighetshandstycke påverkar böjhållfastheten hos zirkonia.Material och metodFemtio provkroppar av yttriumoxidstabiliserad tetragonal zirkonia framställdes med CAD/CAM.
