  1. 11. 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

  3. 12. The effect of furniture on room acoustic parameters and its dependence on the sound absorbing properties of the ceiling

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk akustik; Lunds universitet/Institutionen för byggvetenskaper

    Författare :Huong Nguyen; [2023]
    Nyckelord :Room acoustics; furniture; Sabine s formula; SEA model; sound absorption; sound scattering; reverberation time; speech clarity; sound strength; Technology and Engineering;

    Sammanfattning : In ordinary public rooms such as classrooms and offices, the base line of acoustical treatment is an absorbent suspended ceiling. Due to the non-uniform distribution of the absorptive ceiling material, the scattering as well as the absorption properties of furniture will have a significant effect on room acoustic parameters such as reverberation time, speech clarity and sound strength.

  4. 13. Mechanistic Model Development for a Multi-Enzyme Protein Hydrolysis Process

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Tito Nilsson; [2023]
    Nyckelord :Mechanistic Model; Enzyme; Hydrolysis; Chemical Engineering; Technology and Engineering;

    Sammanfattning : New food products are constantly put on the market. Today the focus often lies in creating nutritional and sustainable products to reduce the environmental impact of the product in question. One example of this is the approval of the yellow mealworm, Tenebrio Molitor, as a novel food in the European union. LÄS MER

  5. 14. Reconfigurable Intelligent Surfaces : Optimal Positioning and Coverage Improvement

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

    Författare :Noé Bernadas i Busquets; [2023]
    Nyckelord :6G; Reconfigurable Intelligent Surfaces; Wireless Communications; Coverage; 6G; omkonfigurerbara intelligenta ytor; trådlös kommunikation; täckning;

    Sammanfattning : Med framväxten av framtida mobilgenerationer bortom 5G, studeras nya teknologier för att tillgodose de förväntade kraven för framtida tjänster som Ultra-Reliable Low Latency Communications (URLLC) eller Virtual Reality. Bland dessa teknologier uppstår Reconfigurable Intelligent Surfaces (RIS) som en av de mest lovande på grund av deras förmåga att förbättra kanalen samtidigt som de bara ökar nätverkets energiförbrukning måttligt.

  7. 15. Energy Poverty: Geospatial Modelling in 2021 Berlin using publicly available data : KTH Thesis Report

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Rita Aparici Quiñones; [2023]
    Nyckelord :;

    Sammanfattning : Energy services are essential for human development and well-being, and the unequal distribution of them leads to inequalities and vulnerabilities. Energy poverty, generally understood as the inability to heat a household, is an increasingly pressing issue that in the context of political and climatic instabilities could affect more and more households.
