1. 16. Effektivisering av klimatberäkningar för ombyggnadsprojekt : För projekt under 50 MSEK hos Akademiska hus

   Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Byggteknik och byggd miljö

   Författare :Elsa Rudqvist; Ominder Bhogal; [2023]
   Nyckelord :effektivisering; schablonvärden; klimatberäkning; koldioxidekvivalenter; livscykelanalys; ombyggnadsprojekt.;

   Sammanfattning : The construction industry is currently responsible for a large amount of greenhouse gas emissions that contribute to the enhanced greenhouse effect. In hopes of facilizing a sustainable development, a new law came in force 2022 requiring climate declarations for new construction projects. LÄS MER

3. 17. Finding ways to develop a sustainable bioeconomy: The case of industrial cassava in Colombia : Environmental impact and food security insights from a combined life cycle assessment and interview study

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Isabel Nilsson Alarcón; [2023]
   Nyckelord :industrial cassava; food security; land use; climate change; biodiversity loss; sustainable bioeconomy; Life Cycle Assessment LCA ; Colombia; industriell kassava; tryggad livsmedelsförsörjning; markanvändning; klimatförändring; minskad biodiversitet; hållbar bioekonomi; livscykelanalys LCA ; Colombia;

   Sammanfattning : Cassava has been identified as a potential key crop for a sustainable bioeconomy in Colombia.However, the bioeconomy is not inherently sustainable, and neither is producing cassava,which makes research on it crucial. Increasing biomass circularity could be key for increasingthe cassava industry’s sustainability performance. LÄS MER

4. 18. Lifecycle Assessment of a Lithium-ion Battery Storage System for Frequency Regulation in a Real-World Application

   Magister-uppsats,

   Författare :Samuel Sulemanu; [2023]
   Nyckelord :Frequency Containment Reserve - Disturbance FCR-D ; Frequency Regulation; Life Cycle Assessment LCA ; Lithium-ion Battery; Simapro; Renewable Energy; Solar PV; Wind; Energy; Climate Change;

   Sammanfattning : Integrating more renewable energy sources into the grid has caused increased instability due to the intermittency of renewable energy sources. Hence, the need for grid balancing strategies such as frequency regulation has intensified. LÄS MER

5. 19. Life cycle assessment on sodium-ion cells for energy storage systems : A cradle-to-gate study including 16 environmental perspectives, focusing on climate change impact

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Rebecca Nibelius; [2023]
   Nyckelord :Sodium-ion batteries; Life cycle assessment; Cradle-to-gate; Natriumbatterier; Livscykelanalys; Vagga-till-port;

   Sammanfattning : Because of the changing energy supply landscape, with the transition towards renewable energy, an emerging demand for energy storage systems (ESS) is expected in the near future. Battery energy storage is promising to contribute to mitigate the greenhouse gas emissions, but face issues considering resource use (IEA, 2023; IRENA, 2022). LÄS MER

7. 20. Human Rights Violations and Machine Learning - Cluster Analysis of Countries using the CIRIGHTS Dataset

   Magister-uppsats, Lunds universitet/Statistiska institutionen; Lunds universitet/Nationalekonomiska institutionen

   Författare :Emilie Ståhle; Emilie Haubrich; [2023]
   Nyckelord :Human Rights Violation; Clustering; K-Means; Latent Class Analysis; Transition Matrix; Business and Economics;

   Sammanfattning : This master's thesis explores the use of unsupervised machine learning techniques to cluster countries based on their degree of human rights violations. Accordingly, the study evaluates the performance of two clustering methods, K-Means clustering and Latent Class Analysis (LCA), using two cluster validation metrics (Silhouette Coefficient and Dunn Index), as well as an Accuracy measure using the Human Rights index.
