1. 1. Estimating the relative phase-difference in EEG using the matched phase reassigned cross-spectrogram

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Maria Åkesson; [2021]
   Nyckelord :Mathematics and Statistics;

   Sammanfattning : In brain connectivity research the relative phase between two EEG oscillations is particularly relevant, as it could provide information about the conduction delay between two regions. However, due to EEG signals containing large amounts of noise and spurious connections, the relative phase is seldom estimated. LÄS MER

3. 2. Method for coupling modulatedscattered light from free flyinginsects to harmonics and theirrelative phases

   Master-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Matematisk statistik

   Författare :Martin Patricks; Ludvig Anderberg; [2020]
   Nyckelord :frequency estimation; phase estimation; matched phase reassignment; entomologic lidar; modulation spectroscopy; scattered light; Technology and Engineering;

   Sammanfattning : Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. LÄS MER

4. 3. Unbiased pitch detection and phase estimation in entomological lidar

   Master-uppsats, Lunds universitet/Matematisk statistik

   Författare :Johan Fogelmark; [2019]
   Nyckelord :Entomological lidar; wing beat frequency estimation; phas; Mathematics and Statistics;

   Sammanfattning : Good insect monitoring is important for both disease vector control and e?cient usage of pesticides in farming. Entomological lidar has been proven useful for detecting and monitoring insects. For every insect that transit the laser beam a backscatter signal containing species-specific information is obtained.
