1. 1. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

   Författare :Lukas Jonasson; [2023]
   Nyckelord :Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

   Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER

3. 2. Agile robotic arm for vertical applications - Evaluation, design and development

   Master-uppsats, Lunds universitet/Maskinelement

   Författare :Rasmus Gren; [2023]
   Nyckelord :Robotic arm development; HKM; Kinematics; Product development; Technology and Engineering;

   Sammanfattning : Existing pick and place robots are either heavy or have a limited workspace for vertical operations. Since there is no robot today that are both light and have a good vertical workspace, this leads to a gap in the market. LÄS MER

4. 3. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

   Författare :Aayush Desai; [2023]
   Nyckelord :Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

   Sammanfattning : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. LÄS MER

5. 4. Development of an event generator for antihyperon-hyperon pair production in antiproton-proton collisions

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Vitor Jose Shen; [2022]
   Nyckelord :MC event generator; Antihyperon-hyperon pair; Antiproton-proton collisions; PANDA; ROOT; 4-vector kinematics; Angular distribution;

   Sammanfattning : The goal of this project was to develop a lightweight Monte-Carlo (MC) event generator for hyperon pair production in antiproton-proton collisions, and demonstrate it in one of the hyperon decay reaction channels, which is collisions of proton and antiproton to lambda hyperon and anti-lambda hyperon, and they decay to antiproton-positive pion pair, and proton-negative pion pair. The prototype of this external MC event generator we presented here is based on the software framework of ROOT. LÄS MER

7. 5. CP Violation Studies in Cascade Decay Sequence

   Kandidat-uppsats, Uppsala universitet/Kärnfysik

   Författare :Roman Sultanov; [2022]
   Nyckelord :CP violation; cascade; decay; asymmetry parameters; polarisation; uncertainty;

   Sammanfattning : This thesis studies CP violation in the decay of the Ξ− hyperon, also known as the cascade baryon, which decays in the sequence Ξ− → Λπ− → pπ−π−. A difference between the angular distribution of this decay sequence and the angular distribution of the charge conjugate decay sequence ͞Ξ+ →͞Λπ+ → ͞pπ+π+, after taking into account the inversion of the momenta due to the parity operation, is indicative of CP violation.
