  1. 21. Oral contraceptive phases and performance : Strength, anaerobic capacity, and lactate responce

    Kandidat-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Isa Rönneblad; Elsa Ohrås; [2023]
    Nyckelord :Performance; oral contraceptive; contraception; Wingate; IMTP; anaerobic capacity; strength; percieved energy level; lactate; prestation; p-piller; preventionsmedel; anaerob förmåga; styrka; upplevd energinivå; laktat;

    Sammanfattning : Background: Oral contraceptives are common among female athletes. Still, its effects on athletic performance are poorly investigated. Research in the area has increased in recent years. However, the study qualities and designs are often insufficient and with small sample sizes. LÄS MER

  3. 22. Wideband Dielectric Resonator Antenna Array for Autonomous Vehicles

    Uppsats för yrkesexamina på avancerad nivå, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Andreas Johansson; Luke Müller; [2023]
    Nyckelord :DRA; dielectric resonator antenna; 5G; FR2; 28GHz; NR; antenna; circular polarization; autonomous vehicles;

    Sammanfattning : With the rapid advancement of autonomous vehicles, reliable and efficient wireless communication systems with high data rates have become essential for their safe and efficient operation and further evolution. High data rates are found in the higher frequency bands where conductive antennas lack radiation efficiency. LÄS MER

  4. 23. Flexibilitetsåtgärder i uppvärmningssystemet: En undersökning om hur implementering av flexibilitetsåtgärder i uppvärmningssystemet kan reducera uppvärmningskostnaden

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Byggteknik och byggd miljö

    Författare :Marcus Lundström; [2023]
    Nyckelord :flexibilitetstjänster; livscykelkostnader; värmelager; värmepump;

    Sammanfattning : In 2022, Sweden faced significant challenges in its energy landscape due to a combination of factors, including Russia's invasion of Ukraine, domestic disruptions in nuclear power production, low water reservoir levels, and the increasing reliance on intermittent energy sources. Consequently, the price of electricity in Sweden soared to unprecedented levels. LÄS MER

  5. 24. Technical performance modelling and optimization of PVT collectors in GSHP integration

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

    Författare :Marin Courcault; [2023]
    Nyckelord :PVT; ISO9806:2017; mass flow; use conditions; test conditions; coefficients optimization; TRNSYS; PVT; ISO9806:2017; massflöde; användningsförhållanden; testförhållanden; optimering av koefficienter; TRNSYS;

    Sammanfattning : In order to contribute to reducing the CO2 emissions related to heating in housing buildings, PVT+GSHP systems appear to be interesting solutions and therefore need to be further investigated to optimise their design and increase their deployment on the field. This thesis focused on building PVT model, using the ISO9806:2017, to be integrated in a PVT+GSHP model and determining optimal PVT design parameters for this system. LÄS MER

  7. 25. Towards Affordable Sodium-Ion Batteries : Mechanochemical Synthesis and Electrochemical Assessment of Iron-Based Fluorophosphate Cathode Material

    Master-uppsats, KTH/Materialvetenskap

    Författare :Ratna Juwita; [2023]
    Nyckelord :Sodium-ion batteries; electrical energy storage EES ; iron oxide; positive electrode; material characterization; electrochemical; discharge capacity.; Natriumjonbatterier; elektrisk energilagring EES ; järnoxid; positiv elektrod; materialkarakterisering; elektrokemisk; urladdningskapacitet;

    Sammanfattning : An urgent transformation from fossil fuels to cleaner energy sources to combat climate change has led to the utilization of renewable energies like solar, wind, and tidal power. However, the intermittency of these sources hinders their wider implementation. To address this, large-scale electrical energy storage (EES) systems are needed. LÄS MER
