  1. 1. Svenska gymnasieelevers svårigheter med bevis i geometri : En empirisk undersökning med van Hieles teori som ramverk

    Uppsats för yrkesexamina på avancerad nivå, Linköpings universitet/Analys och didaktik; Linköpings universitet/Tekniska fakulteten

    Författare :Donna Mach; Nils Strandler; [2023]
    Nyckelord :Geometri; bevisföring; bevis; van Hiele; svårigheter;

    Sammanfattning : Detta arbete undersöker svenska gymnasieelevers bevisföringsförmåga inom geometri med van Hieles modifierade modell som ramverk. Studien bygger på vårt tidigare examensarbete Elevers svårigheter med bevisföring inom geometri (Strandler & Mach, 2022), där internationella studier kring området sammanfattades. LÄS MER

  3. 2. Space-Division-Multiplexing Platform for a Delayed-Choice Experiment

    Master-uppsats, Linköpings universitet/Informationskodning

    Författare :Hilma Karlsson; [2023]
    Nyckelord :Wheeler s delayed choice; wave-particle delayed choice; Sagnac interferometer; Mach-Zehnder interferometer; complementarity relation; spatial modes; space-division-multiplexing; LP-modes; few-mode fibers; quantum communication; quantum optics;

    Sammanfattning : This master’s thesis explores a space-division-multiplexing (SDM) platform fora delayed-choice experiment. SDM is a multiplexing technique for optical datatransmission that employs spatial modes in a multi- or few-mode fiber to increasethe transmission capacity. The spatial modes can thus be used as separate channels. LÄS MER

  4. 3. Machine Learning for State Estimation in Fighter Aircraft

    Master-uppsats, KTH/Optimeringslära och systemteori

    Författare :Axel Boivie; [2023]
    Nyckelord :State estimation; machine learning; fighter aircraft; neural networks; long short- term memory; LSTM; sensor fusion; air data system; ADS.; Tillståndsestimering; maskininlärning; stridsflygplan; neurala nätverk; sensorfusion; luftdatasystem.;

    Sammanfattning : This thesis presents an estimator to assist or replace a fighter aircraft’s air datasystem (ADS). The estimator is based on machine learning and LSTM neuralnetworks and uses the statistical correlation between states to estimate the angleof attack, angle of sideslip and Mach number using only the internal sensorsof the aircraft.

  5. 4. Characterizing the performance of a Real-Timesystem with task execution times

    Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Achilleas Karassavas; Sebastian Sjöberg; Andreas Grönlund; [2023]
    Nyckelord :;

    Sammanfattning : The purpose of this project work was to assist Hitachi Energy by analyzingdata logs from their MACH control system. The system itself operates athigh speeds, resulting in a huge amount of data each second. By writingtwo scripts in Python, statistical analysis was applied to the data followedby comparisons across multiple data logs. LÄS MER

  7. 5. Identifying Fundamental Characteristics of Shock Nonstationarity using MMS Measurements : Identifying and Distinguishing Non-stationary Behaviour Through the Magnetic Field Gradient in Quasi-perpendicular Shocks

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Hannah Wik; [2023]
    Nyckelord :Space; Space Plasma Physics; Collisionless Shocks; MMS; Non-stationarity; Shock Reformation; Rippling; Bow Shock; Solar Wind; Rymd; Rymdfysik; Kollisionsfria chocker; MMS; Icke-stationär; Reformation; Bogchock; Solvind;

    Sammanfattning : Collisionless shocks are widespread phenomena in the universe, and understanding the mechanisms behind their energy dissipation, with a rare number of collisions between particles, remains a significant unresolved question. The Earth’s bow shock provides an excellent opportunity to study this phenomena in situ. LÄS MER
