  1. 1. Social Policy from Above? : Europeanisation of Swedish Social Policy 1990-2019

    Master-uppsats, Stockholms universitet/Sociologiska institutionen

    Författare :Jakob Strigén; [2023]
    Nyckelord :Social policy change; social policy; Europeanisation; welfare state; unemployment policy; family policy; process tracing;

    Sammanfattning : At the same time as the European Union’s (EU) influence has grown, path-breaking changes in Sweden’s social policy characteristics have appeared. Previous research gives contradictory evidence on whether and how these developments relate, and it remains unknown to what extent the EU contributed to the changes observed in Sweden. LÄS MER

  3. 2. 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

  4. 3. Ray Tracing Algorithm for Dielectric Domes

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

    Författare :Maria Pubill; [2023]
    Nyckelord :Array antenna; dielectric dome; Ray-Tracing; reflection; absorption losses; matching layers; Arrayantenn; dielektrisk kupol; strålföljning; reflektion; absorptionsförluster; anpassningsskikt;

    Sammanfattning : Almost hemispherical scanning capabilities are required for modern wireless communication systems to produce broad coverage without performance degradation. Phased array antennas are commonly used as a fully-electronic beam-steering solution for its rapidity in beam switching. LÄS MER

  5. 4. Multifinality in Ontological Security Theory : A Methodological Framework

    Master-uppsats, Uppsala universitet/Statsvetenskapliga institutionen

    Författare :Frida Lampinen; [2023]
    Nyckelord :Ontological security; OST; Multifinality; China;

    Sammanfattning : This thesis problematizes the incomplete understanding of multifinality in ontological security theory. The literature suggests two different interpretations of OST, but the relationship between these has so far received insufficient attention. LÄS MER

  7. 5. Design of a Dielectric Radome using a Ray-Tracing Model for Satellite Communications

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

    Författare :Flores Espinosa Núria; [2023]
    Nyckelord :Dielectric radome; Ray tracing; Array antenna; Lens antenna; Satellite communications; Radom dielèctric; Traçat de Rajos; Arranjament d’antenes; Antena de lent; Comunicacions per satèl·lit; Dielektrisk radome; Strålspårning; Gruppantenn; Linsantenn; Satellitkommunikation;

    Sammanfattning : In recent years, there has been a huge increase in the use of satellite communications. This has led to a need for more capacity, which can be solved by moving towards higher frequency bands in search of higher bandwidths. LÄS MER
