  1. 1. Molecular Insights into the Interactions of Monovalent Cations with Highly charged Fatty Acid Monolayers

    Master-uppsats, KTH/Kemi

    Författare :Ran Carlhamn Rasmussen; [2023]
    Nyckelord :VSFS; Langmuir monolayer; ion specific effects; modified Poisson Boltzmann; carboxylic acid; VSFS; Langmuir monolager; jonspecifika effekter; modifierad Poisson Boltzmann; karboxylsyra;

    Sammanfattning : Vibrational sum frequency spectroscopy har använts för att studera interaktionerna mellan monovalenta joner och laddade fettsyramonolager. Subfasen bestod av utvalda alkalihydroxidsaltlösningar med pH12, med huvudfokus på cesiumjonen. LÄS MER

  3. 2. Evaluating Thread network performance, locating and strengthening weak radio links

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Sammanfattning : One important aspect of stage performance for non-classical singers is stage monitoring. Amplified instruments along with drums often compete in frequency and sound level which affects the audibility on stage, both in detail and as a whole. LÄS MER

  7. 5. Estimation of respiratory frequency from Heart Rate Variability

    Master-uppsats, Lunds universitet/Matematisk statistik

    Författare :Daniel Ågärd; [2023]
    Nyckelord :time-frequency analysis; multitaper spectrogram; Optimization; signal processing; heart rate variability; Mathematics and Statistics;

    Sammanfattning : In this master's thesis the ability to estimate the respiratory frequency from heart rate variability measurement is analyzed. The goal was to implement a solution that is easily transferable to real time. LÄS MER
