  1. 11. Activity quantification of 177Lu using a 360◦ CZT gamma camera - comparison with a dual-head Anger camera

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Albin Lindvall; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and Aim: New SPECT cameras that use CZT detectors in a 360◦ configuration has recently been introduced. Together with Bayesian reconstruction methods employing Median Root Prior (MRP) and Relative Difference Prior (RDP), this constitutes an alternative to Anger-based SPECT for activity quantification.

    Sammanfattning : The EU has proposed an ambitious goal to achieve widespread E-mobility in both the electrical and commercial sectors. To accomplish this, a substantial number of DC fast-charging stations must be built. LÄS MER

  4. 13. A Contingency Framework for Assessing the Commercial Potential of Utility-scale Agrivoltaics

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik, konst och samhälle

    Författare :Filippa Larsson; [2023]
    Nyckelord :Agrivoltaic; Agriphotovoltaic; AV; AGV; Solar Photovoltaic; Solar PV; Commercialization; Commercial Potential; Utility-scale; Contingency Framework; Stakeholder s ; Renewable Energy; Renewables;

    Sammanfattning : Purpose - In the pursuit of renewable energy sources, solar photovoltaic (PV) is predicted to become the single biggest global source of energy by the year of 2027, part of a trilemma involving climate change, biodiversity and food security. Agrivoltaic (AV) systems, the co-location and potential symbiosis between agricultural activities and solar PV, has thereby arisen as a potential solution for dual land-use. LÄS MER

  5. 14. Design and Control of Bidirectional Converters for DC Microgrids

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

    Författare :Gustav Eckerbom; Villiam Petermann; [2023]
    Nyckelord :;

    Sammanfattning : This study aims to summarize the design of two common types of bidirectional DC-DC convertersfound in microgrids, as well as use two distinct control methods for each converter and validate theirperformance. Microgrids are decentralized, small-scale power systems that can operateindependently of the main power grid and are an important solution in order to integrate moreintermittent energy sources, such as solar and wind power, into the energy mix.

  7. 15. Study, Design and Optimization of Micro Coil for NMR Applications

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Yuxuan Lu; Xinhang Li; [2023]
    Nyckelord :NMR;

    Sammanfattning : Nuclear Magnetic Resonance (NMR) has emerged as a powerful tool for the iden-tification and quantification of substances. A critical component within the NMRapparatus is the radio frequency coil, which determines to some extent the sen-sitivity of the NMR device. LÄS MER
