  1. 1. Measuring the Pulse Duration and the Time-Dependent Polarisation State of Ultrashort Laser Pulses with the D-Scan Technique

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Atomfysik

    Författare :Daniel Díaz Rivas; [2022]
    Nyckelord :pulse characterisation; ultrashort; laser; femtosecond; dispersion scan; polarisation; wave plate; temporal reconstruction; electric field reconstruction; time-dependent polarisation; polarisation gate; Physics and Astronomy;

    Sammanfattning : Ultrashort laser pulses with time-dependent polarisation states have many applications, such as the generation of isolated attosecond pulses and the study of the optical chirality of molecules. In this project the polarisation gate, built from two quarter-wave plates of different orders, is thoroughly characterised in experiment and simulation. LÄS MER

  3. 2. Patient-Specific 3D Printed Guides for Corrective Osteotomies of Malunited Radius

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Carolin Skyborn; [2020]
    Nyckelord :Osteotomy; Radius malunion; 3D; 3D printing; Mathematics and Statistics;

    Sammanfattning : The purpose of this master thesis was to expand an existing medical modelling software, Segment 3DPrint, and develop a tool for surgical planning for corrective osteotomy of the forearm. Fractures of the forearm are very common and in some patients the fractured bone unites abnormally, causing a deformation. LÄS MER

  4. 3. The impact of metallic cranial implants on proton-beam radiotherapy treatment plans for near implant located tumours : A phantom study on the physical effects and agreement between simulated treatment plans and the resulting treatment for near implant located cranial tumours

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Adam Sjögren; [2018]
    Nyckelord :Proton-based Radiotherapy; Cranial implants; Titanium implants; Cancer treatment; metal streak artifacts.;

    Sammanfattning : Within the field of radiotherapy treatments of tumour diseases, the hunt for more accurate and effective treatment methods is a continuous process. For some years ion-beam based radiotherapy, especially the proton-beam based applications, has increased in popularity and availability. LÄS MER

  5. 4. Tidseffektivisering av Stora Ensos emballeringsprocess : Simulering av värmeledning och luftflödesberäkningar

    Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Författare :Isabelle Hultin; [2017]
    Nyckelord :packaging; paperboard; paperboard roll; simulation; time saving; time efficiency; emballage; emballering; kartong; kartongrulle; simulering; tidsbesparing; tidseffektivisering;

    Sammanfattning : Stora Enso Skoghalls Bruk är en av de största kartongtillverkarna på vår planet. Var sjätte kartongförpackning i världen som innehåller något flytande kommer från Skoghalls Bruk. Kartong har liten påverkan på miljön då huvudråvaran, trä, är en naturlig råvara. LÄS MER

  7. 5. Topology optimization process for new designs of reconstruction plates used for bridging large mandibular defects

    Master-uppsats, Linköpings universitet/Institutionen för medicinsk teknik

    Författare :Linn Lemón; [2016]
    Nyckelord :Topology optimization; Reconstruction plate; Mandibular defect; Clenching task; Design; SimLab; HyperMesh; OptiStruct;

    Sammanfattning : Loss of bone in the mandible as a result from for example resection of bone tumors or trauma, can in more complex cases be reconstructed using a reconstruction plate to provide stability between the remaining mandible stumps. Different studies on reconstruction plates present a fracture rate of 2.8-9.8 %. LÄS MER
