  1. 11. Mathematical modeling and analysis of hot carrier solar cells

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

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

    Sammanfattning : 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. LÄS MER

  3. 12. Modelling of a Heat Conduction Calorimeter Used in Cement Plant Automation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Hassan Alzeidi; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : 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. LÄS MER

  4. 13. Aromatic Ring Flips and Local Volume Fluctuations in BPTI

    Master-uppsats, Lunds universitet/Biofysikalisk kemi

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

    Sammanfattning : 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. LÄS MER

  5. 14. Examining the Post-purchase Behaviour of Second-hand Clothing : Extending Expectation Confirmation Theory

    Master-uppsats, Karlstads universitet/Handelshögskolan (from 2013)

    Författare :Frida Hjerpe; [2022]
    Nyckelord :Collaborative fashion consumption; post-purchase behaviour; expectation confirmation theory; Swedish consumers;

    Sammanfattning : Amongst production industries, the fashion industry is one of those with the most negative impact on the environment. Globalization has driven consumption of contemporary fashion products, such as clothes, to the highest quantities ever recorded in history. LÄS MER

  7. 15. EVALUATING CHALLENGES, BENEFITS, AND DEPENDABILITY OF VIRTUAL AND PHYSICAL TESTING OF EMBEDDED SYSTEMS SOFTWARE

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Wahaab Alhasan; [2022]
    Nyckelord :;

    Sammanfattning : Software testing is a widely used quality assurance activity and often starts from the early development stages. However, starting early in the development process raises difficulties and challenges practitioners must deal with; most typically, hardware is not available in the required quantities, and there is the risk of damaging the hardware while testing.
