    Sammanfattning : Silicon Carbide, a wide band gap (WBG) semiconductor, has pushed electrical limits beyond Silicon (Si) when it comes to power electronics. It has offered the electrification of society showing promise for a greener future. LÄS MER

  3. 2. Evaluation of Geopositioning Using Frequency Responses From Radio Propagation Measurements

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

    Författare :Jessica Ye; Johan Lesko; [2023]
    Nyckelord :;

    Sammanfattning : Satellite reliant navigation systems may struggle in urban environments as tall buildings mayobstruct necessary direct lines of sight with satellites. There have been multiple studiesexamining how WIFI fingerprinting may be used for indoor positioning. LÄS MER

  4. 3. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

    Magister-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emil Adam Jonatan Östberg; [2023]
    Nyckelord :skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Sammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER

  5. 4. Dissemination of Geographic Location Data in Low Bandwidth Radio Networks

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Johan Olsson; [2023]
    Nyckelord :Ad hoc network; OLSR; MPR; GNE; SCB; SMF; Aquarius;

    Sammanfattning : On the battlefield, having accurate positions of allied troops is crucial for making effective decisions. However, obtaining this information can be challenging, particularly outside of one's own battalion network. LÄS MER

  7. 5. Towards a tunable, wide-band acoustic transducer operating in the quantum regime.

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Abel Hugot; [2022]
    Nyckelord :Hybrid quantum systems; Acoustics; Impedance matching; SQUIDs; Hybrida kvantsystem; Akustik; Impedansanpassning; SQUIDs.;

    Sammanfattning : In the past decade we have seen fast development of new quantum technologies that promise to revolutionise communications and computing. Many different routes are explored to physically implement such quantum technologies. Among others, we can mention superconducting circuits, spin-based devices and photonic devices. LÄS MER
