1. Decay Chains of Fast Alpha Emitters in the Actinide Region
Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : With the advent of increasingly advanced spectroscopic instruments after the turn of the century, it has become accessible to unravel the structure of instantly ‘vanishing’ nuclei, with lifetimes as short as 1 μs, and responsible for pile-up events in analog electronics. Experimental data has been recorded by the Nuclear Structure Group at Lund University for 48Ca/50Ti + nat. LÄS MER
2. Probability Based Path Planning of Unmanned Ground Vehicles for Autonomous Surveillance : Through World Decomposition and Modelling of Target Distribution
Master-uppsats, Linköpings universitet/ReglerteknikSammanfattning : The interest in autonomous surveillance has increased due to advances in autonomous systems and sensor theory. This thesis is a preliminary study of the cooperation between UGVs and stationary sensors when monitoring a dedicated area. The primary focus is the path planning of a UGV for different initial intrusion alarms. Cell decomposition, i. LÄS MER
3. Hydrodynamic Modelling of Spread of Perfluoroalkyl Octanoic Sulphonate and Perfluoroalkyl Hexanoic Sulphonate in Lake Ekoln
Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapsläraSammanfattning : Per and polyfluoroalkyl substances (PFAS) are found ubiquitously in the environment across the globe.These substances have high persistence due to the strong carbon and fluorine bond. In the aquaticenvironment, due to high persistence, these substances don’t decay easily and are detected on the surfaceas well as in groundwater sources. LÄS MER
4. Assessment of the Capability for Vetoing Beta-Decay Events in the Lundium Decay Station
Kandidat-uppsats, Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : Alpha decay spectroscopy using the latest and most sensitive detector setup as well as fast sampling read-out electronics has become very important for discovery and analysis of short-lived nuclei created in collision experiments in the laboratory. The Nuclear Structure Group in Lund is currently developing the Lundium Decay Station for use in comprehensive nuclear spectroscopy of decays for rare isotopes, particularly in the heavy & superheavy region.

5. CP Violation in Σ0 decay
Master-uppsats, Uppsala universitet/KärnfysikSammanfattning : The non-trivial structure of the QCD vacuum gives rise to a P and CP violating term in the QCD Lagrangian. The fact that we do not see an observable CP violation in the strong interaction despite this CP violating theta term is called the Strong CP Problem. LÄS MER
