1. Temporal Localization of Representations in Recurrent Neural Networks
Master-uppsats, Högskolan Dalarna/Institutionen för information och teknikSammanfattning : Recurrent Neural Networks (RNNs) are pivotal in deep learning for time series prediction, but they suffer from 'exploding values' and 'gradient decay,' particularly when learning temporally distant interactions. Long Short-Term Memory (LSTM) and Gated Recurrent Units (GRU) have addressed these issues to an extent, but the precise mitigating mechanisms remain unclear. LÄS MER
2. An alternative explanation for scale-free speed correlations in starling flocks: coarse-graining in time
Master-uppsats, Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)Sammanfattning : In a celebrated series of experimental observations, starling flocks have been shown to be characterized by scale-free, long-ranged spatial correlations in their velocity fluctuations. While this is expected for velocity orientation correlations on the basis of simple symmetry-breaking arguments, the same scaling-free behaviour for speed (i.e. LÄS MER
3. Factors Influencing Farmers’ Readiness for Climate Change Adaptation: Southwest Washington, USA & Skåne, Sweden
Master-uppsats, Lunds universitet/Avdelningen för Riskhantering och SamhällssäkerhetSammanfattning : Climate change impacts global agricultural systems through changes in average temperature, precipitation quantity and timing, and extreme weather events. Climate change adaptation (CCA) for agricultural systems will be based on changes to farms’ day-to-day operations and long-range planning, governmental policies and regulations, and broad changes in supply chains.

4. Investigating RT using two-particle angular correlations in proton-proton collisions
Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionenSammanfattning : The observable, RT , is investigated using two-dimensional (∆η, ∆φ) angular correlations, where ∆η and ∆φ are the differences in pseudorapidity and azimuthal angle respectively, between the trigger and associated tracks. The analysed data consists of reconstructed tracks, from proton-proton collisions at collision energy ps = 13 TeV, taken from the ALICE detector at the LHC. LÄS MER
5. Method development for the analysis of PFAS and neutral precursors in active and passive air samplers
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : Poly- and perfluoroalkyl substances (PFAS) are a chemical class of global concern because of their persistence, toxicity and widespread presence in the environment. This work aimed to develop a robust and reliable method to analyse perfluorohexane sulfonic acid (PFHxS), perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS), as well as the neutral volatile PFOS precursors, namely perfluorooctane sulfonamides and perfluorooctane sulfonamidoethanols (FOSAs/FOSEs).
