  1. 11. Automated Measurement of Relative HF Antenna Properties using WSPR

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

    Författare :Axel Blomqvist; [2023]
    Nyckelord :;

    Sammanfattning : The performance of antennas is an important factor in creating a well performing radio communication channel. Traditionally measuring High Frequency (HF) antennas is an expensive and complicated process. J. Zander[1] proposes an alternative method of evaluating antenna performances in the HF band. LÄS MER

  3. 12. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Karl Herlin; [2023]
    Nyckelord :quantum mechanics; quantum physics; philosophy of physics; interpretation of quantum mechanics; measurement problem; problem of preferred basis; problem of non-observability of interference; problem of definite outcomes; environment induced superselection rules; copenhagen interpretation; decoherence; irreducibility of classical concepts;

    Sammanfattning : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. LÄS MER

  4. 13. Spatial and Temporal Dynamics of  Carbon Sequestration in Stockholm  County's Green areas : A GIS-based Analysis

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

    Författare :Victoria Kareflod; [2023]
    Nyckelord :Carbon sequestration; carbon dynamics; decarbonization; scenario analysis; Corine land cover analysis; urban vegetation; carbon offset; Paris agreement; koldioxidlagring; koldynamik; dekarbonisering; scenarioanalys; marktäckesanalys; stadsvegetation; koldioxidkompensation; parisavtalet;

    Sammanfattning : The human influence of global climate is an issue currently assessed in various mitigation strategies. Stockholm County has committed to becoming carbon neutral by 2040 and negative by 2045 according to the Paris agreement. LÄS MER

  5. 14. On quantum systems and the measurement problem

    Master-uppsats, Stockholms universitet/Fysikum

    Författare :Nicolas Boulle; [2023]
    Nyckelord :Quantum physics; the measurement problem; quantum information; Hilbert spaces; physical systems; unitary; collapse; Euler angles parametrization; Copenhagen interpretation; many- world; measure;

    Sammanfattning : We focus on the Tensor Product Structure (TPS) of the Hilbert space and the fact that a choice in the TPS has an impact on the representation of the studied quantum system. We define the measurement problem in quantum mechanics and present some theories about quantum mechanics, each of them highlighting a different approach to quantum measurements. LÄS MER

  7. 15. Mäta HRR från Li-jonbatterier med hjälp av OCC (oxygen consumption calometry) och andra metoder

    Kandidat-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Olof Skyllberg; [2023]
    Nyckelord :Litium-jon batteri; Termisk rusning; Oxygen consumption calorimetry OCC ; Sensible enthalpy rise approach SERA ; effektutveckling. Lithium-ion batteries; Thermal runaway; Heat release rate.; Technology and Engineering;

    Sammanfattning : One of the most important parameters to measure in the fire discipline is the heat release rate (HRR). Therefore it is very important that these measurements are accurate and as correct as possible. The most common method for measuring heat release rate of fires is the OCC method (oxygen consumption calorimetry). LÄS MER
