  1. 1. The Pseudo-Unitary Group U(p,q) in Quantum Magnonics

    L3-uppsats, Uppsala universitet/Materialteori

    Författare :Maximilian Meyer-Mölleringhof; [2024]
    Nyckelord :quantum magnonics; materials theory; pseudo-unitary; quantum mechanics; magnons; antiferromagnets;

    Sammanfattning : The study of magnons is an essential part of combining quantum information science and spintronics, allowing for the investigation of quantum properties such as entanglement in solid-state devices. Magnons are commonly described using the theory of T. Holstein and H. LÄS MER

  3. 2. Resurseffektiv bevattning i ett föränderligt klimat

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Salman Rahman; [2024]
    Nyckelord :Irrigation; agriculture; Gotland; Storsudret; IoT based irrigation; automated irrigation; mobile solarpanels; solar irrigation; water saving; yield increase; Bevattning; jordbruk; Gotland; Storsudret; IoT baserad bevattning; automatiserad bevattning; mobila solceller; bevattning med solenergi; vattenanvändning; skördmängd;

    Sammanfattning : Södra Gotland (Storsudret) är ett av de mest utsatta områdena i Sverige när det kommer till torka under somrarna. Trots stora mängder nederbörd har jordbrukare problem med bevattning då öns geologi påverkar lagringen av vatten i form av grundvatten negativt. LÄS MER

  4. 3. Battery profit optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Ebba Helfer; [2023]
    Nyckelord :Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Sammanfattning : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. LÄS MER

  5. 4. Control of carbon dioxide capture from biomass CHP plants : Designing a suitable control system to realize the flexible operation of the CO2 capture system

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Tanmmay Rout; [2023]
    Nyckelord :Carbon capture; biomass fired combined heat and power plant; MEA based chemical absorption; flue gas; dynamic operation; PI controllers;

    Sammanfattning : This degree project studies the integration of carbon capture system into biomass fired combined heat and power (bio-CHP) plants. The key disturbances from bio-CHP plants include flue gas flow rate, carbon dioxide (CO2) concentration and available heat for the reboiler because the use of versatile biomass and the dynamic operation of CHP plants results in large fluctuations in the properties of flue gas and the heat input for CO2 capture.

  7. 5. Ray-Tracing Modeling of Grating Lobe Level Reduction by Using a Dielectric Dome Antenna

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

    Författare :Lukas Jonasson; [2023]
    Nyckelord :Array antenna; Dielectric dome; Ray-Tracing; Grating lobe; Particle Swarm optimization; Gruppantenn; Dielektrisk kupol; Strålspårning; Gallerlob; Particle Swarm optimering;

    Sammanfattning : With the newly deployed fifth-generation telecommunications system and upcoming sixth-generation, high-gain antennas with hemispherical scanning capabilities are of high interest. Phased array antennas allow for fast scanning capabilities with electronic beam-steering. LÄS MER
