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

    Författare :HongShuo Yi; Duosi Dai; [2023]
    Nyckelord :LoRa; Indoor IoT Internet of Things ; Signal strength; Round-trip time RTT ; Goodput; LoRaWAN device classes; AVR-RSS2; RIOT-OS; LoRa; Inomhus-IoT Internet of Things ; Signalstyrka; Rundresa-tid RTT ; Goodput; LoRaWAN klasser; AVR-RSS2; RIOT-OS;

    Sammanfattning : This thesis is dedicated to measuring the communication performance of LoRa technology in an indoor environment and providing insight into its potential application as an effective Internet of Things (IoT) communication solution in Low Power Wide Area Networks (LPWAN). Through careful experimentation and analysis, we assessed various transmission parameters such as spreading factor (SF), bandwidth (BW), Payload Length (PL), and LoRaWAN classes. LÄS MER

    Sammanfattning : Hydropower is an important part of renewable power production in Sweden. The voltage stability of the already existing hydropower needs to be improved. One way to do this is by improving the control system that damp terminal voltage oscillations. LÄS MER

  5. 4. Fotbollsspelarnas upplevelser av agenter efter agentlicensens avreglering

    Kandidat-uppsats, Malmö universitet/Institutionen Idrottsvetenskap (IDV)

    Författare :Adnan Huseincehajic; [2021]
    Nyckelord :deregulation of the agent license; trust; competence; professionalism; avreglering av agentlicensen; förtroende; kompetens; professionalitet;

    Sammanfattning : The purpose of this study has been to investigate how the deregulation of the agent license has affected football players' experiences of agents in general, the trust in agents and the experience of the agents' competence and professionalism. To gain an understanding of the football players' experiences, the Rational Choice theory was chosen, where the Principal Agent theory was used to explain the results of the study. LÄS MER

  7. 5. Excitation system – simulation, tuning and evaluation

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Philip von Heideken; [2021]
    Nyckelord :;

    Sammanfattning : Swedish Electrical and Power Control AB (Svea Power) offers excitation systems for electrical production plants. An excitation system controls the electrical performance of the generator’s three phase outputs and must meet requirements set out in the business agency “Svenska Kraftnäts (SvK:s) föreskrifter, SvKFS 2005:2”.
