  1. 1. Development of an absorption model for gas discharge lamp simulation

    Master-uppsats, Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Författare :Oscar Vigstrand; [2021]
    Nyckelord :Discharge lamp; Plasma; UV radiation;

    Sammanfattning : Ultraviolet (UV) light has been used for disinfection purposes for over 100 years. Irradiation by UV light is a method to disinfect surfaces in order to prevent microbiological growth. At Tetra Pak this is of great importance as they are manufacturer of filling machines. LÄS MER

  3. 2. Hyperfine structure measurements in scandium for IR spectroscopy

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Felix van Deelen; [2017]
    Nyckelord :Astrophysics; Atomic Data; Hyperfine Structure; Stellar Spectroscopy; Physics and Astronomy;

    Sammanfattning : Stellar abundances are important for understanding the chemical evolution of galaxies and provide us with constraints on stellar evolution and supernova nucleosynthesis. To determine stellar abundances accurately, atomic data is crucial. This data is incomplete for many elements, especially in the infrared region. LÄS MER

  4. 3. Lysande rör, rörligt ideal : belysningsbranschens introducerande av lysröret i Sverige

    Kandidat-uppsats, Institutionen för kultur, energi och miljö

    Författare :Jonas Eriksson; [2012]
    Nyckelord :Lysrör; lysämnesrör; belysning; belysningsarmatur; rationellt ljus; armatur; lampor; 1930-tal; 1940-tal; Ljuskultur; ERA; Siemens; Luma; Philips; Orrefors; NK; Böhlmarks; Malmö metallvarufabrik;

    Sammanfattning : During the 1930´s the hot potato for the Swedish lighting associations were how to create the most suitable light for every situation, either for industries, offices or homes. The light bulb were the most frequently used source of light but due to limitied luminous intensity, big halls sometimes required up to hundreds of light bulbs to produce the right amount of light.

  5. 4. Laboratory Spectroscopy of Neutral Scandium, Sc I, for Astrophysical Applications

    Master-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Författare :Asli Pehlivan; [2012]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Most of the things that we know about stars come from their spectrum. The properties of the atomic lines, e.g. energy levels, wavelengths, oscillator strengths, must be known to understand the observed spectrum and to perform quantitative analyses. LÄS MER

  7. 5. Research on the Best Market Applications for LightLab Energy-Saving Lamps

    Master-uppsats, Energisystem

    Författare :Raul Vilalta Cea; [2010]
    Nyckelord :Research; Market; Applications; LightLab; Lightlab; Energy; Saving; Lamps; Lamp; Lighting; Environment; Sweden; Light; Mercury; Free; Field; Emission; Cathodoluminescence; LightLab; katodluminiscens; fältemission; ljusteknologi; lampa;

    Sammanfattning : Nowadays, lighting represents 20% of the global electricity consumption. Light can be produced using different technologies but more than 100 years after its invention, the incandescent bulb is still the most sold and one of the more used light sources. LÄS MER
