  1. 1. A cross-correlation analysis of a warm super-Neptune using transit spectroscopy

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Elias Önerud; [2023]
    Nyckelord :Cross-correlation; cross-correlation spectroscopy; cross-correlation analysis; super-Neptune; astronomy; astrophysics; WASP-107; WASP-107 b; CRIRES ; SysRem; exoplanet; transmission spectrum; transit;

    Sammanfattning : A study was made in order to deduce whether certain chemical species, namely water (H2O) and carbon monoxide (CO), are present in the atmosphere of the exoplanet WASP-107 b, which lies about 200 light-years away from Earth in the constellation Virgo. The project was carried out at Uppsala University at the Department of Physics and Astronomy. LÄS MER

  3. 2. Construction of a scanning confocal microscope for Quantum Dot mapping at telecom wavelength

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Alexandros Bampis; [2023]
    Nyckelord :Nanophotonics; Quantum Dot Positioning; Photoluminescence Mapping; Scanning Microscope; Nanofotonik; Positionering av kvantprickar; Fotoluminescenskartläggning; Skanningsmikroskop;

    Sammanfattning : Future commercial applications making use of non-classical light sources require bright quantum emitters. Such emitters can be achieved by embedding self-assembled, optically active semiconductor quantum dots (QDs) in centered photonic structures. LÄS MER

  4. 3. Speaker verification: Advantages and limitations of a biologically inspired feature extractor

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Maja Gajic; [2022]
    Nyckelord :Speaker verification; artificial neural network; ANN; feature extractor; Technology and Engineering;

    Sammanfattning : Speaker verification is the process of verifying the identity of a person based on voice. This process usually encompasses the following steps: The speech signal is mapped into features using a feature extractor, these features are then classified using a post processor. LÄS MER

  5. 4. Effects of water-vapor on the Ka/Q band Earth-space radio propagation channel

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Joar Marchner Brandt; [2021]
    Nyckelord :Attenuation Alphasat Water-vapor Oxygen Cloud ITU Budapest;

    Sammanfattning : A higher frequency radio channel both increase the possible data rate and de- crease the required antenna size to efficiently transmit data. Higher frequency also introduce larger weakness to signal loss due to atmospheric effects. Al- phasat satellite conduct experiments for future use of higher frequencies by the Aldo Paraboni Payload.

  7. 5. Building a Fluorescence Correlation Spectroscopy (FCS) instrument followed bytesting the boundaries of FRET-FCS

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Isabell Weinberg-Krakowski; Evelina Stenseth; [2021]
    Nyckelord :;

    Sammanfattning : Understanding biological systems oftentimes requires mapping the behaviors of biomolecules on small scales such as single proteins or nucleic acids. Fluorescence Correlation Spectroscopy (FCS) is a group of particularly noninvasive and sensitive fluorescence-­based techniques that can be used for this purpose. LÄS MER
