  1. 21. Magnetic field of the magnetic chemically peculiar star V1148 Ori

    Kandidat-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Kristoffer Pettersson; [2023]
    Nyckelord :chemically peculiar star; magnetic fields; deconvolution; zeeman effect; polarization;

    Sammanfattning : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. LÄS MER

  3. 22. Spinor-Helicity Formalism and ScatteringAmplitudes in Various Dimensions

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Chen Huang; [2023]
    Nyckelord :;

    Sammanfattning : In recent decades, spinor-helicity formalism has gained popularity as a useful tool for studyingscattering amplitudes in four dimensions. This formalism has been extended to higher dimensions,but there is still much work to be done around its application. LÄS MER

  4. 23. Improving network performance with a polarization-aware routing approach

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

    Författare :Jingyi Pan; [2023]
    Nyckelord :Traffic engineering; Hash function; Multipath routing; Trafikteknik; Hash-funktion; Flervägsdirigering;

    Sammanfattning : Traffic polarization in networks refers to the phenomenon where traffic tends to concentrate along specific routes or edges when doing multipath routing, leading to imbalanced flow patterns. This spatial distribution of traffic can result in congested and overburdened links, while other routes remain underutilized. LÄS MER

  5. 24. Designing Diverse Features to Reduce the Filter Bubble Effect on Social Media

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

    Författare :Ramya Kandula; [2023]
    Nyckelord :Filter bubbles; recommender systems; diversity; social media; filter bubblor; rekommenderande system; mångfald; sociala medier;

    Sammanfattning : The filter bubble effect has been an active area of research that has been explored in various contexts within social media. Research on recommender system designs within filter bubbles has received a lot of attention, mainly due to its impact on the phenomena. LÄS MER

  7. 25. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Andreas Johansson; Luke Müller; [2023]
    Nyckelord :DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Sammanfattning : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. LÄS MER
