  1. 1. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :David Ek; [2023-01-09]
    Nyckelord :;

    Sammanfattning : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. LÄS MER

  3. 2. Design and Implementation of a Rocket Launcher Hybrid Navigation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Omar Ugolini; [2023]
    Nyckelord :launch vehicle navigation; delayed Kalman filter; strapdown; navigering av bärraketer; fördröjt Kalman-filter; strapdown;

    Sammanfattning : Rocket Factory Augsburg (RFA) a German New Space Startup is developing a three-stage rocket launcher aiming at LEO/SSO orbits. A fundamental responsibility of the GNC team is the development of the rocket navigation algorithm to estimate the attitude, position, and velocity allowing the guidance and control loops to autonomously steer the rocket.

  4. 3. Robustness Against Non-Normality : Evaluating LDA and QDA in Simulated Settings Using Multivariate Non-Normal Distributions

    Kandidat-uppsats, Uppsala universitet/Statistiska institutionen

    Författare :Gånheim Viktor; Åslund Isak; [2023]
    Nyckelord :Classification; Linear Discriminant Analysis; Quadratic Discriminant Analysis; Normality Assumption;

    Sammanfattning : Evaluating classifiers in controlled settings is essential for empirical applications, as extensive knowledge on model-behaviour is needed for accurate predictions. This thesis investigates robustness against non-normality of two prominent classifiers, LDA and QDA. LÄS MER

  7. 5. The effect of age and different speech tasks on the Acoustic Voice Quality Index

    Magister-uppsats, Umeå universitet/Logopedi

    Författare :Rosanna Rehn; [2023]
    Nyckelord :AVQI; acoustic voice quality index - acoustic evaluation - overall voice quality - multiparametric voice assessment - sustained vowel - continuous speech;

    Sammanfattning : Background Previous research has emphasized the importance of objectivity in voice quality evaluation. Acoustic voice quality index (AVQI) is a multiparametric objective index, that quantifies overall voice quality. Over the past decade, international studies have demonstrated strong diagnostic accuracy and sensitivity of AVQI to voice disorders. LÄS MER
