  1. 1. Production of the Σ0-bar hyperon in the PANDA experiment at FAIR

    Master-uppsats, Uppsala universitet/Kärnfysik

    Författare :Gabriela Pérez Andrade; [2019]
    Nyckelord :PANDA; hadrons; hyperons;

    Sammanfattning : The PANDA experiment is one of the main pillars of the Facility for Antiproton and Ion Research (FAIR), currently under construction in Darmstadt, Germany. PANDA will be a fixed target experiment designed for the study of non-perturbative phenomena of the strong interaction. LÄS MER

  2. 2. A comparative study of ZnO i-layer deposited with ALD and PVD for CIGS solar cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Joel Johansson Byberg; [2019]
    Nyckelord :CIGS; ZnO; ZnMgO; solar cells; thin film; zinc oxide; window layer; ALD; PVD;

    Sammanfattning : Two identified setbacks for CIGS based devices in order to obtain higher efficiency are parasitic absorption in the window layer structure and losses in open-circuit voltage due to bad interfaces. This study investigated how the performance of the solar cell is affected by depositing intrinsic ZnO (i-ZnO) and ZnMgO with atomic layer deposition (ALD) instead of the conventional sputtering.

  3. 3. AP&T Machine and Line Usability : A usability analysis of stand-alone machines and production lines at AP&T

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för ekonomi, teknik och samhälle

    Författare :Fanny Åkerström; [2019]
    Nyckelord :Usability; user experience; user needs; human-machine interaction; press hardening; industry; digitalization; automation; production solution; development; Användarvänlighet; användarupplevelse; användarbehov; HMI; presshärdning; industri; digitalisering; automation; produktionslösning; utveckling;

    Sammanfattning : Automation and digitalization are developing at a high pace and it is important to keep the focus on human-machine interaction. It is becoming more and more important that the usability in machines and lines is related to the development so that the performance and availability of the production processes in the industry are not adversely affected.

  4. 4. GIS-Based approach to estimate the energy requirements of the post-harvest activities in Souss-Massa basin in Morocco

    Master-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :Francesco Agostini Fantini; Javier Izaguirre Carbonell; [2019]
    Nyckelord :;

    Sammanfattning : Over the last decades the Moroccan agriculture has passed through a complete transformation: due to the low workforce cost and its favourable climate, the sector has attracted the attentions of national and foreign investment and thus has expanded rapidly. Among the different productions, tomatoes proved to be one of the most profitable, generating 4. LÄS MER

  5. 5. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

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

    Författare :Linnea Lindh; [2019]
    Nyckelord :Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. LÄS MER
