  1. 1. Consensus Algorithms in Blockchain : A survey to create decision trees for blockchain applications

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

    Författare :Xinlin Zhu; [2023]
    Nyckelord :Blockchain; Cryptocurrency; Consensus Algorithms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree; Blockchain; Kryptovaluta; Consensus Algoritms; Proof of Work; Proof of Stake; Hybrid Consensus; Decision Tree;

    Sammanfattning : Blockchain is a decentralized database that is distributed among a computer network. To enable a smooth decision making process without any authority, different blockchain applications use their own consensus algorithms. The problem is that for a new blockchain application, there is limited aid in deciding which algorithm it should implement. LÄS MER

  3. 2. Prediktion av hjärtsjukdom

    Kandidat-uppsats, Uppsala universitet/Informationssystem

    Författare :Stefan Sandberg; Max Hård af Segerstad; [2023]
    Nyckelord :;

    Sammanfattning : Hjärt- och kärlsjukdomar är den vanligaste enskilda dödsorsaken i både Sverige och världen i stort, och utgör ungefär en tredjedel av alla dödsfall. Maskininlärning används som medel för riskbedömning av sjukdomar inom sjukvården och visar på stor potential, men ingen konsensus har hittills nåtts kring vilken klassificeringsalgoritm som når högst träffsäkerhet vid klassificering av hjärt- och kärlsjukdomar.

  4. 3. Privacy-Preserving Alternating Direction Method of Multipliers

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

    Författare :Ivar Källström; Lukas Gamard; [2023]
    Nyckelord :;

    Sammanfattning : As machine learning models affect our lives more strongly every day, developingmethods to train these models becomes paramount. In our paper, we focus on the problem ofminimizing a sum of functions, which lies at the heart of most - if not all - of these trainingmethods. LÄS MER

  5. 4. Consensus Algorithm with Input Constraints and Collision Avoidance for Swarming Sunshade Satellites near the L1 point

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Felicia Törning; [2022]
    Nyckelord :Consensus algorithm; Formation control; Multi agent system; Solar sailing; Space based geoengineering; Konsensusalgoritm; Formationskontroll; multiagent system; solsegel;

    Sammanfattning : Swarm Control Theory studies how multi-agent systems interact to solve tasks cooperatively. In this thesis it was studied how graph theory and the Dynamic Average Consensus Algorithm can be used to control swarming sunshade satellites near L1 for global temperature control, and if it would be suitable for the purpose.

  7. 5. Comparison between consensus algorithms in an IIoT network : Analysis of Proof of Work, Proof of Stake and Proof of Authentication

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Baran Polat; Ilyas Göcmenoglu; [2022]
    Nyckelord :Proof of work; Proof of stake; IIoT; Proof of authentication; Blockchain; CloudRail; electricity consumption; time effectiveness; security; Proof of work; Proof of stake; IIoT; Proof of authentication; Blockkedja; CloudRail; elkonsumtion; tidseffektivitet; säkerhet;

    Sammanfattning : The Industrial Internet of Things (IIoT) is growing day by day and is implemented in many industries. The centralized architecture of an IIoT system is composed of several devices that communicate with a special device only via one link, in an instance where this one link is attacked, major problems could occur for the whole system.
