1. 1. Childhood family structure in 16 European countries

   Master-uppsats, Stockholms universitet/Sociologiska institutionen

   Författare :Andreas Gustafsson; [2024]
   Nyckelord :child outcomes; Europe; comparative; divorce; stepfamily; sequence analysis;

   Sammanfattning : At the end of the 20th century we saw great changes in family dynamics with rates ofseparation and re-partnerning increasing across Europe. Previous research has primarilyfocused on adults but less is known about how these family demographic changes haveaffected children's family structure. LÄS MER

3. 2. Riparian plant biodiversity and community composition of ditches and straightened streams : identifying key environmental drivers in a boreal forest setting

   Master-uppsats, SLU/Dept. of Forest Ecology and Management

   Författare :Rasmus Staaf; [2024]
   Nyckelord :artificial waterways; riparian zone; novel ecosystems; ; forestry; ditch network maintenance; species richness; hill-diversity; drainage ditches; coarse woody debris; ditch cleaning; ecology;

   Sammanfattning : Modified ecosystems are typically seen as degraded and having no ecological value. In many cases, the modification of the ecosystem was done more than 100 years ago and may have had time to recover and become a refugia for species that were once more common in the landscape.

4. 3. Dynamic minimum flows in the bypass reach of Juktån : A post-implementation evaluation of the effects on riparian vegetation

   Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

   Författare :Walter Gezelius Gezelius; [2024]
   Nyckelord :Restoration; Environmental flows; riparian vegetation;

   Sammanfattning : The purpose of the paper was to evaluate the effects of the restoration efforts in Juktån on the plant species richness and composition, vegetation zonation and soil composition. The restoration involved implementation of a dynamic flow, in addition to hydro-geomorphological alterations. LÄS MER

5. 4. Variational AutoEncoders and Differential Privacy : balancing data synthesis and privacy constraints

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

   Författare :Baptiste Bremond; [2024]
   Nyckelord :TVAE; Differential privacy; Tabular data; Synthetic data; DP-SGD; TVAE; differentiell integritet; tabelldata; syntetiska data; DP-SGD;

   Sammanfattning : This thesis investigates the effectiveness of Tabular Variational Auto Encoders (TVAEs) in generating high-quality synthetic tabular data and assesses their compliance with differential privacy principles. The study shows that while TVAEs are better than VAEs at generating synthetic data that faithfully reproduces the distribution of real data as measured by the Synthetic Data Vault (SDV) metrics, the latter does not guarantee that the synthetic data is up to the task in practical industrial applications.

7. 5. Deep reinforcement learning for automated building climate control

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Erik Snällfot; Martin Hörnberg; [2024]
   Nyckelord :Machine Learning; Reinforcement Learning; Deep Learning; Deep Reinforcement Learning; Building Control; Control System;

   Sammanfattning : The building sector is the single largest contributor to greenhouse gas emissions, making it a natural focal point for reducing energy consumption. More efficient use of energy is also becoming increasingly important for property managers as global energy prices are skyrocketing. LÄS MER
