  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. HYDROGEN-FIRED GAS TURBINE FOR POWER GENERATION WITH EXHAUST GAS RECIRCULATION : Emission and economic evaluation of pure hydrogen compare to natural gas

    Master-uppsats, Mälardalens högskola/Framtidens energi; Mälardalens högskola/Framtidens energi

    Författare :Nemir Gibrael; Hamse Hassan; [2019]
    Nyckelord :harmful emission; natural gas; fuel reforming process; hydrogen fired gas turbine; exhaust gas recirculation; techno-economic analysis;

    Sammanfattning : The member states of European Union aim to promote the reduction of harmful emissions. Emissions from combustion processes cause effects on human health and pose environmental issues, for example by increasing greenhouse effect. LÄS MER

  4. 4. Adoption of high-technology products in emerging markets: The ACE-1 advanced biomass cookstove in rural Cambodia

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Anne Baltruschat; [2019]
    Nyckelord :Sustainable Development; Energy access; Clean cooking; Advanced biomass stoves; Adoption;

    Sammanfattning : This study examines the adoption of clean cooking technologies in developing countries with a focus on the ACE-1 advanced biomass stove (ABS). Marginalized communities in rural environments are often exposed to high levels of Household Air Pollution (HAP) due to the common use of traditional cookstoves. LÄS MER

  5. 5. Capacity Management in Hyper-Scale Datacenters using Predictive Modelling

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Xhesika Ruci; [2019]
    Nyckelord :Capacity Management; Efficient Datacentre; Predictive Modelling. Accuracy Metrics;

    Sammanfattning : Big data applications have become increasingly popular with the emerge of cloud computing and the explosion of artificial intelligence. Hence, the increasing adoption of data-hungry machines and services is driving the need for more power to keep the datacenters of the world running. LÄS MER
