  1. 1. Characterizing Bitcoin Use For Illicit Activities

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Hampus Rosenquist; [2023]
    Nyckelord :Bitcoin; illicit; characterization; bitcoin abuse; crypto; cryptocurrencies; cryptocurrency; Bitcoin; illegalt; illegal; olagligt; karaktärisering; bitcoinmissbruk; krypto; kryptovaluta; kryptovalutor;

    Sammanfattning : Bitcoin's decentralized nature enables reasonably anonymous exchange of money outside of the authorities' control. This has led to Bitcoin being popular for various illegal activities, including scams, ransomware attacks, money laundering, black markets, etc. LÄS MER

  3. 2. Validation of Simultaneous T1 and T2 Mapping Using Cardiac Magnetic Resonance Fingerprinting in Self-Constructed Phantoms : An Analysis of the Reproducibility and Accuracy

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Sasithon Meesan; [2023]
    Nyckelord :Cardiac Magnetic Resonance Fingerprinting cMRF ; Cardiac Magnetic Resonance Imaging CMR ; Simultaneous T1 and T2 Mapping; Validation; Accuracy; Reproducibility; Cardiac Magnetic Resonance Fingerprinting cMRF ; Kardiovaskulär Magnetresonans CMR ; Simultant T1 och T2 Parametrisk-Karaktärisering; Validering; Noggrannhet; Reproducerbarhet;

    Sammanfattning : Quantitative cardiac magnetic resonance imaging (CMR) has gained traction within both the clinical and research field due to high prevalence of cardiovascular diseases. Cardiac magnetic resonance fingerprinting (cMRF) is a novel approach introduced to address the limitation associated with evaluation of multiparametric quantitative CMR. LÄS MER

  4. 3. The cosmological polytope of the complete bipartite graph K_{2,n}

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Erik Landin; [2023]
    Nyckelord :Polytopes; Cosmological polytopes; Gröbner bases; Graphs; Polytop; Kosmologiska polytop; Gröbner baser; Grafer;

    Sammanfattning : A cosmological polytope of an undirected connected graph is a lattice polytope which when the graph is interpreted as a feynman diagram can be used to calculate the contribution of that feynman diagram to the wavefunction of some cosmological models. This contribution can be calculated using the canonical form of the cosmological polytope, which can be computed by taking the sum of the canonical forms of the facets of a subdivision of the cosmological polytope.

  5. 4. En studie om lakvattenhantering vid Gräfsåsensavfallsanläggning : En studie i syfte att föreslå lämpliga system avreningstekniker

    Kandidat-uppsats, Mittuniversitetet/Institutionen för naturvetenskap, design och hållbar utveckling (2023-)

    Författare :Pontus Karlström; [2023]
    Nyckelord :Leachate water; Landfill; Treatment tehnology; BREF characterization; Lakvatten; reningstekniker; deponier; BREF karaktärisering;

    Sammanfattning : För att främja en hållbar utveckling har FN satt upp 17 vägledande globala miljömål som nationell lagstiftning bör utformas efter, vilket Sverige har gjort. För att se till att miljölagstiftningen följs av verksamheter utövas tillsyn mot vissa typer av verksamheter, bland annat deponier. LÄS MER

  7. 5. A Petrographic and Paragenetic Characterization of the Ertelien Ni-Cu Deposit (Norway)

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper
