  1. 11. Viscoelasticity of transparent wood-polymer biocomposites : Measuring the time-dependence of a delignified birch and poly(methyl methacrylate) composite’s mechanical properties, using digital image correlation

    Kandidat-uppsats, KTH/Materialvetenskap

    Författare :Marine Jeanne Debouvry; [2023]
    Nyckelord :;

    Sammanfattning : The viscoelastic behavior of a delignified birch and poly(methyl methacrylate) (PMMA) composite was investigated, in an effort to learn more about the mechanical properties of transparent wood-polymer biocomposites. Tensile creep tests with constant load were performed for native wood, non-delignified, and delignified wood-polymer composites. LÄS MER

  3. 12. Determination of Proton Beam Waist Positions Using Beam Position Monitors

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

    Författare :Gustav Gird Fahlström; [2022]
    Nyckelord :ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

    Sammanfattning : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

  4. 13. Analys av finita element program

    Kandidat-uppsats, KTH/Byggteknik och design

    Författare :Alexis Fredy Ramos Salazar; Samuel Pena Hernandez; [2022]
    Nyckelord :FEM; SOFiSTiK; Brigade standard; Comparative studie; Slab frame bridge.; FEM; SOFiSTiK; Brigade standard; Komparativ studie; Plattrambro.;

    Sammanfattning : FEM program, program som använder finita element metoden, har en långhistoria av användning inom ingenjörsyrken. I modern tid har FEM programblivit en nödvändighet för beräkningar inte bara i byggbranchen, men ocksåinom andra ingenjörsverksamheter där stora mängder beräkningar krävs. LÄS MER

  5. 14. Wide-Angle Radome Design for Low-Cost Additive Manufacturing

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Martin Fajerberg; Mattias Nylander; [2022]
    Nyckelord :Radar; Radome; A-Sandwich; B-Sandwich; Multilayer; Polarization; Angle of Incidence; Finite Element Method; Differential Evolution Optimization; Transmission Line Theory; Honeycomb; Additive Manufacturing; Electromagnetic Theory; Technology and Engineering;

    Sammanfattning : The radome, a portmanteau of the words radar and dome, is a protective dielectric cover to protect a radar from its surrounding environment. The surrounding environment can be rain, wind, sand, dust and whatever else that might harm the radar. LÄS MER

  7. 15. The evidence base of elevated vacuum and pin-lock suspension system in transtibial prosthetic users: A literature review with a systematic approach

    Kandidat-uppsats, Jönköping University/HHJ. Ortopedteknisk plattform

    Författare :Louise Dömstedt; Malin Stafås; [2022]
    Nyckelord :transtibial prosthetics; transtibial suspension method; elevated vacuum; active vacuum; pin-lock;

    Sammanfattning : Aim: This review aims to describe the existing evidence base for using elevated vacuum suspension and pin-lock suspension systems in regards to fluctuations of limb volume, balance, effect on gait (spatial and temporal, kinematic, and kinetic data), and in-socket movement (pistoning and transverse forces). Background: There is a growing population with a TT amputation thus there is an increased demand for TT prosthetic solutions. LÄS MER
