1. 16. N-body simulations of exoplanets and their moons

   Master-uppsats, Lunds universitet/Astrofysik; Lunds universitet/Fysiska institutionen

   Författare :Lydia Schollmeier; [2024]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The planet-planet interactions in a many-planet system cannot be analytically calculated. Instead, they have to be investigated by using an N-body simulation. I discuss three questions about the N-body interactions in planetary systems: The first two are on the system 55 Cnc, a system with five known planets around a K-type star. LÄS MER

3. 17. Indocyanine-green fluorescence imaging to detect anastomotic insufficiency after esophagectomy

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

   Författare :Love Kildetoft; [2024]
   Nyckelord :Fluorescence; Imaging; Indocyanine-green; ICG; Esophageal cancer; Physics; Photonics; Image Analysis; Blood Perfusion; Anastomotic leakage; Anastomotic insufficiency; Physics and Astronomy;

   Sammanfattning : This research project is concerned with the development of simulation models and image analysis algorithms, as well as instrumentation for characterizing anastomotic leakages after a patient has undergone surgery for esophageal cancer. Anastomotic leakage is a high-incidence complication after esophagectomy, a surgical procedure for esophageal cancer. LÄS MER

4. 18. Development of a guide system for free neutron oscillation searches at the European Spallation Source

   Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Lunds Tekniska Högskola; Lunds universitet/European Spallation Source ESS AB

   Författare :Linnéa Björk; [2023]
   Nyckelord :ESS; neutrons; dark matter; antimatter; neutron guides; Physics and Astronomy;

   Sammanfattning : In this project, a neutron delivery system for the study of free neutron oscillations at the HIBEAM beamline at the European Spallation Source (ESS) has been developed. The HIBEAM experiment is part of a two-stage program at ESS which will address open questions in physics; specifically the nature of dark matter and the observed asymmetry between matter and antimatter in the Universe.

5. 19. Exploring the Applications of Machine Learning in the Public Sector

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik - Genomgår omorganisation

   Författare :Adrian Hammarberg Dalmyr; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : Despite the many use cases for machine learning, it sees minimal usage in Sweden’s public sector today. It is important that the public sector in particular utilizes the most efficient tools available. LÄS MER

7. 20. Glauber Monte Carlo for proton-proton and virtual-photon-proton collisions

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

   Författare :Oscar Sepp; [2023]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : In high energy physics, we want to probe the inner structures and behaviours of the particles that are the building blocks of our universe. This is often done by colliding nuclei together. LÄS MER
