  1. 1. Wavelength-dependent limb darkeningin the analysis oftransit spectroscopy of exoplanets

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Alberto García Ribas; [2023]
    Keywords : ;

    Abstract : Limb darkening, an optical effect characteristic of stars, where the limb (edge) seemsto be darker than the centre of the stellar body; plays an important role in our under-standing of exoplanetary transits, as it is fundamental for developing light curve modelsthat can help to undercover extrasolar companions. To recover atmospheric featuresfrom exoplanets, a principal component analysis method is typically used. READ MORE

  3. 2. Solar Photovoltaic Fire Risks : FE-analysis of fire exposed solar photovoltaic systems and comparison of current legislation and recommendations from different countries

    University essay from Luleå tekniska universitet/Byggkonstruktion och brand

    Author : Elin Bergroth; Greta Torstensson; [2023]
    Keywords : Solar Photovoltaic; National Guidelines; Fire Department; FE-analysis; TASEF; Solceller; Nationella Riktlinjer; Räddningstjänst; FE-analys; TASEF;

    Abstract : The global use of energy increases every day and to meet the growing demand, energy sources are constantly being developed to become more efficient and reliable. During the last decade, the global solar photovoltaics (PV) capacity has increased every year and in 2017, solar PV was the global leading power source of renewable energy. READ MORE

  4. 3. Estimating stellar limb darkening using exoplanet transits

    University essay from Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

    Author : Sora Ishida; [2023]
    Keywords : Limb-darkening; CHEOPS; Transit; Exoplanet; PYCHEOPS; Physics and Astronomy;

    Abstract : The brightness of the stars is not uniform over the surface as it varies depending on the wavelength and the atmosphere that the light propagates. Limb darkening is an optical effect caused by a decrease in brightness of the star towards the edge. READ MORE

  5. 4. Determining caffeine and 3-caffeoylquinic acid content in artisanal processed specialty coffee varieties with different roasting grades, origins, and brewing methods

    University essay from Linnéuniversitetet/Institutionen för kemi och biomedicin (KOB)

    Author : Oliver Mihajlovic; [2023]
    Keywords : kaffeanalys; koffein; klorogensyra; HPLC; analytisk kemi;

    Abstract : Coffee is one of the most consumed beverages in the world, with about 10 million tons of coffee consumed in 2021. There are a lot of steps between the coffee tree and served beverage, as there are several processing methods each contributing to differences in fragrance, aroma, and acidity. READ MORE

  6. 5. Saturated planar laser-induced fluorescence using sinusoidal intensity modulation

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Author : Klara Lozani Gerdhem; [2023]
    Keywords : fluorescence; fluorophore; LIF; PLIF; saturated LIF; saturated PLIF; structured light; Physics and Astronomy;

    Abstract : Saturated laser-induced fluorescence (saturated LIF) has been the topic of some research, however mainly regarding laser diagnostic methods conducted on flames. A few papers have discussed saturated LIF with the purpose of producing saturation curves of different fluorescent elements. READ MORE
