  1. 6. Exploring New Physics Through Collider and Gravitational Wave Measurements with Artificial Neural Networks: the Case Study of QCD-like Technicolor

    Magister-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Ashar Ahmed Kamal; [2023]
    Nyckelord :Artificial Neural Networks; ANN; Beyond the Standard Model; BSM; parameter space scan; Physics and Astronomy;

    Sammanfattning : With physicists actively exploring Beyond the Standard Model (BSM) theories that may fill in the gaps of the Standard Model (SM), a fundamental question arises: which parameters hold physical significance? In this thesis, we present our initial progress towards the development of a model-independent artificial intelligence framework designed for conducting parameter space scans in BSM scenarios. Our framework incorporates several publicly available high-energy physics packages, namely SPheno, HiggsBounds, HiggsSignals, and CosmoTransitions. LÄS MER

  3. 7. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  4. 8. Biopolymers processed and used as enzyme carriers

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Dániel Mészáros; [2023]
    Nyckelord :Biobased materials; plasticized sodium alginate; water stability; extraction kinetics; enzyme carrier; Biobaserade material; Mjukgjort natriumalginat; Vattenstabilitet; extraktionskinetik; Enzymbärare;

    Sammanfattning : Syftet med detta masterprojekt var att undersöka möjligheten att använda biobaserat, mjukgjort natriumalginat (NaAlg) som enzymbärare. Alginaterna görs traditionellt bearbetbara genom att tillsätta olika mjukgörare, såsom polyoler (glycerol, sorbitol, etc.), i detta arbete användes glycerol. LÄS MER

  5. 9. Visualization, modeling and consequences of residual stresses in glass frit sealing of a UV light source

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Mikrosystemteknik

    Författare :Vilma Hurtigh Grabe; [2023]
    Nyckelord :bonding; micro system; glass frit; sealing; finite element; modeling; glass; mikrosystem; sammanfogning; glasfog; fog; finita element; modellering; glas;

    Sammanfattning : PureFize Technologies AB develops and manufactures a broadband ultraviolet (UVC) light technology device that is mercury-free and based on nanotechnology, using the principle of field emission. The light source is made of Ti and glass, which are hermetically bonded, using a low-temperature glass frit, at elevated temperatures. LÄS MER

  7. 10. UV laser patterning of silicone-based soft electrode grids

    Master-uppsats, Linköpings universitet/Institutionen för teknik och naturvetenskap; Linköpings universitet/Tekniska fakulteten

    Författare :Maria Jakobsson; [2023]
    Nyckelord :Soft electrodes; Wearable electrodes; UV laser; Laser ablation; Laser curing; Polydimethylsiloxane; PDMS; Silver flakes; Teknisk biologi; Teknisk biologi;

    Sammanfattning : Roughly 123 million people worldwide are affected by conditions such as epilepsy, dementia, and cardiovascular diseases. Wearable electrodes are currently used to monitor these conditions short-term. Long-term monitoring would allow for predicting seizures and could be used as a preventive treatment. LÄS MER
