  1. 16. Secure and Privacy-Preserving Decentralized Wi-Fi Aware Service Discovery Architecture

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

    Författare :Jiahao Wang; [2022]
    Nyckelord :Wi-Fi Aware; Secure Service Discovery; Bloom Filter; TESLA; Client Puzzle; Wi-Fi Aware; Säker Serviceupptäckt; Bloom Filter; TESLA; Klient Pussel;

    Sammanfattning : In modern Mobile Ad hoc Networks (MANETs), service discovery is a major component for mobile devices to exchange data and find available services. However, service discovery architectures developed and adopted by the industry either are not appropriate for MANETs or cannot provide security and privacy protection to clients. LÄS MER

  2. 17. Negative CO2 Emissions from Chemical Looping Combustion: Gas Cleaning for CO2 Storage

    Master-uppsats, KTH/Kemiteknik

    Författare :Laura Raud Pettersson; [2022]
    Nyckelord :Chemical Looping Combustion; Flue Gas Treatment; Negative emissions; Biomass; CCS; Linde Hampson; Cryogenic Separation; Kemcyklisk Förbränning; Rökgasrening; Negativa Utsläpp; CCS; Biomassa; Linde Hampson; Kryogen Destillation;

    Sammanfattning : Kemcyklisk förbränning (CLC) involverar en icke komplex separation av den bildade koldioxiden (CO2) efter förbränningen eftersom syret (O2) överförs till bränslet via en syrebärare som cirkulerar mellan luft- och bränslereaktorn. Eftersom O2 separeras effektivt från kvävgasen (N2) i luftreaktorn, erhålls en produkt gas som till majoriteten består av CO2 och vatten (H2O). LÄS MER

  3. 18. Self-Supervised Transformer Networks for Error Classification of Tightening Traces

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

    Författare :Dennis Bogatov Wilkman; [2022]
    Nyckelord :Transformers; Self-supervised Learning; Multi-Label Error Classification; Tightening Traces; Transformatorer; Självövervakad Inlärning; Klassificering av fel med flera etiketter; Skärpnings spår;

    Sammanfattning : Transformers have shown remarkable results in the domains of Natural Language Processing and Computer Vision. This naturally raises the question whether the success could be replicated in other domains. LÄS MER

  4. 19. Continuous Parallel Approximate Frequent Elements Queries on Data Streams

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Victor Jarlow; [2021-10-06]
    Nyckelord :computer science; big data; Space-Saving; Misra-Gries summary; frequent items; frequent elements; concurrent programming; Delegation Sketch; domain splitting; Count-Min Sketch; Majority algorithm; pproximate frequent-elements algorithm; approximate top-k elements algorithm;

    Sammanfattning : The frequent elements problem involves processing a stream of elements and finding all elements that occur more than a given fraction of the time. A relaxed version of this problem is the -approximate elements problem which allows some false positives. LÄS MER

  5. 20. External Streaming State Abstractions and Benchmarking

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

    Författare :Sruthi Sree Kumar; [2021]
    Nyckelord :Apache Flink; Distributed Systems; NDB; FlinkNDB; State; State Backends; External State; Stream Processing Systems; Benchmarking; Caching; Apache Flink; Distributed Systems; NDB; FlinkNDB; State; State Backends; External State; Stream Processing Systems; Benchmarking; Caching;

    Sammanfattning : Distributed data stream processing is a popular research area and is one of the promising paradigms for faster and efficient data management. Application state is a first-class citizen in nearly every stream processing system. Nowadays, stream processing is, by definition, stateful. LÄS MER
