  1. 6. Generating Perturbative Solutions for Slowly Rotating Perfect Fluids Using the Hartle Scheme

    University essay from Umeå universitet/Institutionen för fysik

    Author : Elin Johansson; [2023]
    Keywords : ;

    Abstract : In this thesis, we study slowly rotating relativistic stars by modeling them as perfect fluids. The Hartle formalism is used to perturb a spherically symmetric static solution into slow rotation and the corresponding field equations to second order are presented. READ MORE

  3. 7. Pulse Shape Analysis of Si Detector Signals from Fission Fragments using the LOHENGRIN Spectrometer

    University essay from Uppsala universitet/Tillämpad kärnfysik

    Author : Dimitrios Papaioannou; [2023]
    Keywords : plasma delay time; PDT; pulse shape analysis; waveform; LOHENGRIN; nuclear; fission;

    Abstract : Nuclear physics experiments typically involve the collection and analysis of detector signals produced by the interaction of subatomic particles with matter to deduce various quantities. When heavy ions are involved, Si Detector signals are distorted by the formation of a plasma-like cloud from the interaction between the heavy ions and the detector material. READ MORE

  4. 8. Mathematical modeling and analysis of hot carrier solar cells

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Benjamin van Dijk; [2023]
    Keywords : solar cell; nanowires; hot carrier; nanowire; analysis; mathematical model; trends; fermi function; reservoirs; Physics and Astronomy;

    Abstract : This thesis focuses on the analysis of a mathematical model of a nanowire based hot carrier solar cell. The relevance of the topic comes from the energy crisis society is facing today. Firstly, we discuss the basic principle of hot carrier solar cells and discuss several energy loss factors. READ MORE

  5. 9. Modelling of a Heat Conduction Calorimeter Used in Cement Plant Automation

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Hassan Alzeidi; [2022]
    Keywords : Technology and Engineering;

    Abstract : A model is used to describe a system physically or mathematically and to give information about changes in the system variables. Physical knowledge about the system and its quantities can be useful to build a physical model obeying the laws of nature. READ MORE

  6. 10. Aromatic Ring Flips and Local Volume Fluctuations in BPTI

    University essay from Lunds universitet/Biofysikalisk kemi

    Author : Simon Enbom; [2022]
    Keywords : Biophysical Chemistry; Molecular Dynamics; Protein Dynamics; Activation Volume; Aromatic Ring Flips; BPTI; Biology and Life Sciences; Chemistry; Technology and Engineering;

    Abstract : Aromatic ring flips are a classic example of a dynamic process in proteins. Discovered decades ago, methodological limitations hindered progress at the time. Ring flips have gained new interest and experimentalists can measure the flip rate and thermodynamic quantities associated with it. READ MORE
