  1. 1. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    University essay from Uppsala universitet/Mikrosystemteknik

    Author : Vilma Hurtigh Grabe; [2023]
    Keywords : bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Abstract : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. READ MORE

  3. 2. Micro-architectured materials for thermal management : Porous graphite/graphene boiling enhancement structures

    University essay from Uppsala universitet/Tillämpad mekanik

    Author : Melody Ghaderidosst; [2022]
    Keywords : Microarchitecture; TPMS; Gyroid; thermo-mechanical; computational homogenization; graphite; graphene;

    Abstract : The convergence of the digital and physical world encourages advances in high-speed telecommunication and fifth generation technology. Two-phase heat transfer systems are common engineering solutions. However, due to the large frequency spectra in 5G, the systematic heat generation increases requiring more efficient thermal management. READ MORE

  4. 3. Live 3D imaging quantum LiDAR

    University essay from KTH/Tillämpad fysik

    Author : Theodor Staffas; [2021]
    Keywords : lidar; otdr; snspd; lidar; otdr; snspd;

    Abstract : In this thesis, I demonstrate a single­photon Light Detection And Ranging, (LiDAR)system operating at 1550 nm capable of reconstructing 3D environments live withmm resolution at a rate of 400 points per second using eye­safe laser pulses. Thesystem was built using off­-the-­shelf optical components and analysis was performedusing open-­source software. READ MORE

    Abstract : I dag sätts flera åtgärder in för att bromsa klimatförändringarna, både inom Sverige och på internationell nivå. ‘Forum för energieffektivt byggande’, FEBY, är en organisation som arbetar med att driva utvecklingen av lågenergibyggnader framåt. READ MORE

  6. 5. Develop Optimization Model for Spheroidal Graphite Iron

    University essay from

    Author : Rehman Babar; [2020]
    Keywords : ;

    Abstract : The main motivation behind this study is to develop a methodology to generate surrogate model coefficients for parametrized Spheroidal Graphite Iron (SGI) for thermal expansion and Young’s modulus response. To accomplish this objective, a 3D model was created by Abaqus, and Python was used for developing the script. READ MORE
