  1. 1. Radio Environment Compensation in a Narrowband IoT Positioning System : Using Radio Signal Metrics Between Stationary Devices

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

    Författare :Elin Berglund; [2023]
    Nyckelord :Positioning; IoT; machine learning; range estimation; Positionering; IoT; maskininlärning; avståndsuppskattning;

    Sammanfattning : The Internet of Things (IoT) has emerged as a powerful tool for meeting our need to collect information about and interact with our environments. One important aspect of this technology is positioning which imposes requirements on both the energy consumption and the arrangement of the systems. LÄS MER

  3. 2. Cross coupling in a two-axis control system for stabilized platforms

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

    Författare :Bill Lavebratt; [2022]
    Nyckelord :MIMO; Modeling; Two-axis gimbal system; Decoupler; Inner loop disturbance compensation; Control theory.;

    Sammanfattning : Inertial stabilized platforms consisting of a two-axis gimbal assembly are often modelled as two independent SISO systems, describing the dynamics of the elevation axis and the azimuth axis respectively. In reality the state of the elevation channel and the state of the azimuth channel affect each other. LÄS MER

  4. 3. Voltage Stability and Reactive Power - Introduction of Intermittent Renewable Energy Sources in a Power System

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

    Författare :Erik Hagström; Tobias Jansson; [2022]
    Nyckelord :Voltage Stability; Reactive Power; Renewable Energy; Wind Power; Power Flow Analysis; MATPOWER;

    Sammanfattning : The electricity demand increases rapidly, and in order to mitigate climate change the power production needs to be renewable and free from green house gas emissions. When solar and wind power are introduced in the system, voltage instability might become a problem. LÄS MER

  5. 4. Power Electronic Enhanced Distribution Transformer : Seamless Voltage Regulation with Extended Functionalities

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

    Författare :Nils Johansson; [2022]
    Nyckelord :Hybrid distribution transformer; Power converters; Voltage control; Hybrid power system; Reactive power; Hybrid distrubitionstransformator; Effektomvandlare; Spänningskontroll; Hybrida elnät; Reaktiv effekt;

    Sammanfattning : On-load tap changers and static synchronous compensators (STATCOM) are the main components for voltage regulation and power quality optimization in the power system. STATCOMs are used in both industrial applications and utility to stabilize the grid and reduce downtime. LÄS MER

  7. 5. Påverkan av hemolys vid analys av neuronspecifikt enolas på Cobas

    Kandidat-uppsats, Malmö universitet/Fakulteten för hälsa och samhälle (HS)

    Författare :Marcella Sarras; [2021]
    Nyckelord :Cobas; hemolysis; hemolysis index; neuron-specific enolase; NSE; Cobas; hemolys; hemolysindex; neuronspecifikt enolas; NSE;

    Sammanfattning : Neuronspecifikt enolas (NSE) är en viktig biomarkör för att diagnostisera t.ex. neuroendokrina tumörer, särskilt småcellig lungcancer (SCLC) och neuroblastom. NSE används även som en del i utredning av hjärnskada vid hjärtstopp. LÄS MER
