  1. 1. Backscatter Communications for 6G

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Lakshmi Rajeev Cheekati; Jin Yan; [2022]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The success of future Internet of Things (IoT) depends on, among the other things, developing energy-effcient communication techniques that can enable information exchange among billions of IoT devices with ultra-low/zero power consumption requirements. Ambient backscatter communications is an emerging technology, which utilizes the ambient Radio Frequency (RF) signal as the carrier to reduce the form-factor, and the battery requirements of low-cost small sensor type communication devices.

  3. 2. Levelised cost of green hydrogen produced at onshore wind farm sites : A case study comparing local production in Sweden and importing from Chile

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Torun Moberg; [2022]
    Nyckelord :hydrogen; wind power; energy storage; ammonia; hydrogen carrier; electrolyzer; LCOH;

    Sammanfattning : Hydrogen can be produced via water electrolysis, a process powered by electricity, and is often called green hydrogen if the electricity source is renewable. The purpose of this thesis is to investigate the levelised cost of hydrogen, LCOH, from two hypothetical scenarios of green hydrogen production at onshore wind farm sites. LÄS MER

  4. 3. Greenhouse Gas Emissions Reduction in the Heavy-Duty Transport Sector - A Case Study of Renewable Energy Carriers in Sweden

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Karolina André; William Degerstedt; [2021]
    Nyckelord :Battery electric vehicle; Biofuels; Greenhouse gas; Heavy-duty vehicles; LCA; Renewable energy carriers; Renewable fuels; TCO; Transport sector; Well-to-wheel; Technology and Engineering;

    Sammanfattning : Den svenska transportsektorn står för ungefär en tredjedel av landets totala utsläpp av växthusgaser och släppte 2019 ut 16,4 Mt CO2-ekvivalenter. Av dessa står den tunga vägtrafiken för cirka 20 % och är efter passagerarfordonen den största källan till utsläpp av växthusgaser inom sektorn. LÄS MER

  5. 4. Blue skies or dark clouds for the pilots and flight attendants? : Loyalty, self-loyalty, commitment and motivation in the flight industry

    Magister-uppsats, Karlstads universitet

    Författare :Rahul Singh; [2020]
    Nyckelord :Loyalty; Self-loyalty; Motivation; Commitment; Pilot; Flight attendant; Flight industry; Low-cost airline; Carrier airlines;

    Sammanfattning : While worldwide the flight industry was increasing in the last decade, little is known about the working environment of pilots and flight attendants. This paper aims to develop a deeper understanding based on the theories of loyalty, self-loyalty, commitment, and motivation for pilots and flight attendants in the low-cost segment and the carrier segment in the flight industry.
