  1. 6. 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

  3. 7. 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.

  4. 8. Anaysis of the Trend of Historical Temperature and Historic CO2 Levels Over the Past 800,000 Years by Short Time Cross Correlation Technique

    Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Författare :Tejashkumar Patel; [2021]
    Nyckelord :Short time crosscorrelation technique; CO2; temperature data;

    Sammanfattning : Carbon Dioxide concentration in Earth’s atmosphere is currently at 417 Parts permillion (ppm) and keep rising. Historic CO2 levels and historic temperature levels hasbeen cycling over the past 800,000 years. LÄS MER

  5. 9. 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

  7. 10. Interaction between cobalt nanoparticles and DPPC at pulmonary conditions

    Master-uppsats, KTH/Yt- och korrosionsvetenskap

    Författare :Paula Sommer; [2021]
    Nyckelord :metallic nanoparticles; lipids; lung surfactants; adsorption; pulmonary fluid; metalliska nanopartiklar; lipider; lungtensider; adsorption; syntetisk lungvätska;

    Sammanfattning : Nanomaterial produceras och används alltmer i tekniska lösningar för att förbättra t.ex. materialegenskaper. Eftersom ett materials egenskaper förändras när det är i nanoskala så påverkas även dess toxikologiska egenskaper. LÄS MER
