  1. 1. Mathematical Modeling and Simulation of Cryogenic Liquid Hydrogen Storage

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Gusten Zandler Andersson; [2023]
    Keywords : Modeling; Simulation; Liquid Hydrogen; Storage tank; Modelica; Chemical engineering; Technology and Engineering;

    Abstract : Liquid hydrogen is an attractive alternative to fossil fuels in the aviation industry, but storing it both before and during flights introduces many challenges pertaining to the cryogenic liquid conditions required. Having reliable models to predict the dynamical behavior inside the storage tank is therefore of great interest. READ MORE

  3. 2. Strain/Stress profile investigation of crystals mounted in an optical instrument via FEM simulation

    University essay from Lunds universitet/Industriell Produktion

    Author : Matheus Amarante Machado; [2023]
    Keywords : Modeling; Abaqus; Y2SiO5; Finite Element Modeling; Strain; Stress; Yttrium Orthosilicate.; Technology and Engineering;

    Abstract : Abstract This work is one of a series of related papers that were made in Lund University. They were done to analyze in a multi scalar way the Yttrium Orthosilicate crystals (YSO), analyzing the variation of material properties stemmed from the mounting, composition and other parameters in the optical properties of Yttrium Orthosilicate crystals.

  4. 3. Design and Fabrication of a Kinetic Inductance Parameric Amplifier for multi-mode entanglement studies

    University essay from KTH/Tillämpad fysik

    Author : Sara Persia; [2022]
    Keywords : Parametric amplifier; kinetic inductance; superconducting NbTiN nanowires; Parametrisk förstärkare; kinetisk induktans; supraledanden NbTiN- nanotrådar;

    Abstract : Parametric amplifiers are essential for analyzing and measuring the weak signals generated byquantum circuits at cryogenic temperatures. This project aims to realize a low noise travelingwave parametric amplifier (TWPA) by exploiting the nonlinear current dependence of thekinetic inductance of superconducting NbTiN nanowires.

  5. 4. Temperature Dependent Electrical Characterisation of Vertical InAs-InGaAs Nanowire MOSFETs

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Sofie Johannesson; Sebastian Skog; [2022]
    Keywords : Vertical InGaAs Nanowire MOSFET Temperature Dependence Noise; Technology and Engineering;

    Abstract : This thesis presents the temperature dependence of InGaAs Nanowire (NW) metal-oxide-semiconductor field-effect transistors (MOSFETs) grown at two different temperatures. The two different growths represent one sample having nanowires which have a mixed crystal structure (showing stacking faults) and one sample with nanowires of pure crystal structure (without stacking faults).

  6. 5. Numerical modelling of cold helium safety discharges from the cryogenic distribution line

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Jonathan Persson; [2020]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source, ESS, is a project currently with 17 Partner Countries, and with Sweden and Denmark as host nations. The ESS main facility is being constructed in Lund, to ultimately become the world’s most powerful neutron source, providing around 30 times brighter neutron beams than any earlier facility. READ MORE
