  1. 1. Jämförelse av OPS, MQTT och DDS med avseende på fördröjningstid och throughput

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Kasper Nilsson; Alicia Bergman; [2023]
    Nyckelord :publish-subscribe; communication protocol; latency; throughput; publish-subscribe; kommunikationsprotokoll; fördröjningstid; throughput;

    Sammanfattning : In this study a comparison of the publish-subscribe communication protocols OPS, MQTT and DDS were conducted. The implementation used for DDS was fastDDS and the client library Paho Eclipse MQTT C++ was used for MQTT with the broker implementation Eclipse Mosquitto. LÄS MER

  3. 2. Towards Water Resource Recovery Facilities : Environmentally Extended Techno-Economic Assessment of Emerging Sewage Sludge Management Technologies in Sweden

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

    Författare :Harry Tibbetts; [2023]
    Nyckelord :Circular Economy; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrothermal Carbonisation; Cirkulär ekonomi; Waste Valorisation; Systems Analysis; LCA; MFA; EFA; TEA; Hydrotermal Carbonization;

    Sammanfattning : Municipal sewage sludge (MSS) management varies widely between countries and legislative regimes. Within the European directive for sewage treatment France applies over half of MSS to arable land, while The Netherlands has banned the practice (Kelessidis et al, 2012). LÄS MER

  4. 3. Automatic Management of Related Data Distribution Service Topics

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Gabriel Kazai; [2022]
    Nyckelord :;

    Sammanfattning : A distributed system is a system that utilizes a network to communicate while usually being broken down into multiple software programs. Said programs generally have separate tasks, and a paradigm used in the manner above is publish-subscribe. LÄS MER

  5. 4. Improvement of the Rucio implementation for the LDCS platform and search for dark data

    Kandidat-uppsats, Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Författare :Piotr Yartsev; [2022]
    Nyckelord :Dark matter; rucio; digital infrastructure; Root; LDMX; LDCS; dark data; Python; CERN; particle physics; big data; Geant4; Light Dark Matter eXperiment; Lightweight Distributed Computing System; data storage; Physics and Astronomy;

    Sammanfattning : In this work we aim to implement a software package to detect and categorize dark data, data not accessible or not known by the user, generated in the simulations of the Light Dark Matter eXperiment (LDMX). This will involve studying current existing solutions for such problems, attempting to implement them for the Lightweight Distributed Computing System (LDCS), and developing our own Dark Data Search (DDS) toolkit to perform the detection and categorization of the dark data.

  7. 5. Integrating Data Distribution Service – DDS – in an existing software architecture : exploring the effects of performance in scaling

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska högskolan

    Författare :Andreas Larsson; [2020]
    Nyckelord :;

    Sammanfattning : Data Distribution Service (DDS) is a flexible, decentralized, peer-to-peer communication middle-ware. This thesis presents a performance analysis of using DDS in the Toyota Smartness platform that is used inside Toyota’s Autonomous Guided Vehicles (AGVs). LÄS MER
