  1. 1. Online Sample Selection for Resource Constrained Networked Systems

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

    Författare :Philip Sjösvärd; Samuel Miksits; [2022]
    Nyckelord :Online learning; Sample Selection; Real-time Learning; Random Forest; Reservoir Sampling; Relevance and Redundancy; Binned Distribution; Autoregressive Model; Change Detection; Model Re-computation;

    Sammanfattning : As more devices with different service requirements become connected to networked systems, such as Internet of Things (IoT) devices, maintaining quality of service becomes increasingly difficult. Large data sets can be obtained ahead of time in networks to train prediction models offline, however, resulting in high computational costs. LÄS MER

  3. 2. Online Learning with Sample Selection

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

    Författare :Cong Gao; [2021]
    Nyckelord :data-driven engineering; online learning; sample selection; model recomputation; datadriven teknik; online-lärande; dataurval; omberäkning av modeller;

    Sammanfattning : In data-driven network and systems engineering, we often train models offline using measurement data collected from networks. Offline learning achieves good results but has drawbacks. For example, model training incurs a high computational cost and the training process takes a long time. LÄS MER

  4. 3. Development of an underwaterruler using an AUV-deployedbeacon and Matched filter CFARdetector

    Master-uppsats, KTH/Marina system

    Författare :Yaolin Ge; [2020]
    Nyckelord :;

    Sammanfattning : Our ocean covers more than 70% of our planet’s surface. It is a huge reservoir continuously supplying us with enormousvaluable resources. The autonomous aquaculture, deep sea mining, subsea oil / gas exploitation and marine biology etc.,are the increasingly important driving forces for the development of underwater robotics. LÄS MER

  5. 4. Estimating greenhouse gas emission via degassing and modeling temperature profiles in tropical reservoirs.

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

    Författare :Johan Wilson; [2020]
    Nyckelord :Metan; Vaxthusgaser; Vattenkraft; Klimat;

    Sammanfattning : The aim of this project was to quantify the greenhouse gas (GHG) emissions from the degassing process ofhydroelectrical reservoirs in tropical regions.Reservoirs represent 25 % of the total area of man-made freshwater systems and are a source of GHG emissions tothe atmosphere.

  7. 5. Frilevande larver av Strongylus vulgaris : en experimentell studie

    Uppsats för yrkesexamina på avancerad nivå, SLU/Dept. of Biomedical Sciences and Veterinary Public Health

    Författare :Julia Ling; [2020]
    Nyckelord :häst; bete; blodmask; strongylus vulgaris;

    Sammanfattning : Den stora blodmasken, Strongylus vulgaris, drabbar hästar på betet. Parasiten har en fekal-oral livscykel som tar ca sex månader att fullborda. Infekterade individer sprider ägg från S. vulgaris via träcken, varpå äggen kläcks och larver utvecklas i träckhögen på betet. LÄS MER
