1. Parameter Update Schemes for Hidden Markov Models applied to Financial Returns
University essay from Lunds universitet/Matematisk statistikAbstract : This thesis was dedicated to investigating the use of different parameter update schemes for Hidden Markov models with time-varying parameters, with an emphasis on developing alternatives to the quasi-Newton step. The focus was on applications to financial returns, using data from the S\&P-500 and the Nikkei index, and for comparison, a trial using synthetic data was also performed. READ MORE

2. Nuclear Structure near the Proton Drip-line: A Search for Excited States in 62Ge
University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionenAbstract : An experiment to study mirror symmetry in the mass A = 60 region was performed at the Argonne National Laboratory (ANL) in 2020. The fusion-evaporation reaction 40Ca + 24Mg → 64Ge* at a beam energy of 106 MeV was used to populate excited states in 62Ge. READ MORE

3. Critical Perspectives on Investor-State Dispute Settlement in the EU after Case C-284/16 - Achmea : Did We Throw Out the Baby with the Bathwater?
University essay from Uppsala universitet/Juridiska institutionenAbstract : The EU is the world’s leading host and source of foreign investment. In the light of the current situation with respect to intra-EU investor-state arbitration, it is, however, questionable whether the EU will be able to retain that position. READ MORE

4. Importance of fish community structure, nutrients and browning for shallow lake ecosystem dynamics : A modelling perspective
University essay from Uppsala universitet/Institutionen för biologisk grundutbildningAbstract : In a changing climate, it is increasingly important to be able to model environmental effects on food webs, and to do that, one must have appropriate dynamic models. I present a shallow lake ecosystem model where producers, grazers, carnivores, piscivores, and detritivores are coupled through resource (light, nutrients and detritus) fluxes between the benthic and pelagic habitats and through carnivore life history events (ontogenetic habitat and diet shifts).

5. Studies of Molecular Carbon Cluster Dianions in DESIREE
University essay fromAbstract : Since the surprising first detection of small carbon cluster dianions by Compton et al 1990, several studies have been made investigating their structure, fragmentation pathways and stability. As other carbon anions have been found in space, it is likely that these dianions exists as well and their ability to react with other molecules is therefore of interest. READ MORE
