1. 1. The Role of Uni- and Multivariate Bias Adjustment Methods for Future Hydrological Projections and Subsequent Decision-Making

   Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

   Författare :Anna Merle Liebenehm-Axmann; [2024]
   Nyckelord :Bias adjustment methods; future hydrological climate projections; statistical analysis; future streamflow analysis; biasjusteringsmetoder; framtida hydrologiska projektioner; statistisk analys; framtida vattenförings analys;

   Sammanfattning : Climate models are essential for generating future climate projections. However, due to simplifications, the models can produce systematic differences between output and reality, which is referred to as model bias. Bias adjustment methods aim to reduce this error, which is important for making future projections more reliable. LÄS MER

   Sammanfattning : Electronic voting systems have the potential to offer a cost effective, secure and transparent way of communicating with the citizens, increasing trust and participation. However creating a secure open source electronic voting system providing confidentiality and transparency with sufficient performance has long been a challenge. LÄS MER

4. 3. Generation and detection of entangled single-photon pairs

   Kandidat-uppsats, Uppsala universitet/FREIA

   Författare :Gabriella Tesfamichael Habtezion; [2024]
   Nyckelord :;

   Sammanfattning : Quantum information technology is an emerging field with important applications such as quantum cryptography and teleportation, quantum imaging and lithography. These applications make use of single photons and pairs of entangled photons. In this work, we experimentally generate and attempt to detect the entangled photons. LÄS MER

5. 4. Detecting Lithium Brine in Afghanistan Using Spaceborne Hyperspectral Data

   Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

   Sammanfattning : The purpose of this thesis is to utilize hyperspectral remote sensing technology for the identification and evaluation of lithium mineral deposits in Afghanistan. Afghanistan boasts unique geological formations with substantial potential for lithium resources beneath its land crust. LÄS MER

7. 5. Methodology for Stored Heat “Heat In Place” (HIP) assessment of geothermal aquifers – Exemplified by a study of the Arnager Greensand in SW Scania

   Master-uppsats, Lunds universitet/Geologiska institutionen

   Författare :Oskar Sundberg; [2023]
   Nyckelord :geothermal energy; geothermal resource assessment; geothermal potential; volume method; volumetric method; recovery factor; direct use; direct heat; Mesozoic aquifers; Earth and Environmental Sciences;

   Sammanfattning : In the sedimentary bedrock of southwest Scania, located in the southernmost part of Sweden, there are several low-enthalpy Mesozoic sandstone aquifers situated at different depths. These aquifers collectively hold the potential for direct-heat geothermal utilization. LÄS MER
