  1. 1. Acid retardation : recovery and recycling of acid and metal

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Industriell miljö- och processteknik

    Författare :Cecilia Bood; [2020]
    Nyckelord :Acid retardation; Ion exchange; Pickling; Stainless steel;

    Sammanfattning : During the production of steel, an oxide scale is formed on the surface and to achieve anadequate quality of the surface the scale needs to be removed. Acid pickling is a surfacetreatment where the oxide scale is removed by acid. LÄS MER

    Sammanfattning : In today's connected society, where it is common to have several connected devices per capita, it is more important than ever that the data you need is omnipresent, i.e. its available when you need it, no matter where you are. We identify one key technology and platform that could be the future—peer-to-peer communication and the Web. LÄS MER

  3. 3. Energianalys komplett biogassystem : En sammanställande analys av en gårdsbaserad biogasanläggnings energiförbrukning

    Kandidat-uppsats, KTH/Energiteknik; KTH/Energiteknik

    Författare :Erika Sandberg; Teodor Tapper; [2020]
    Nyckelord :;

    Sammanfattning : Biogasanläggningar har oftast en relativt låg verkningsgrad och en låg lönsamhet, detta har gjort att biogasens potential inte utnyttjas till fullo utan används endast till några få procent globalt. Till följd av detta har Innovationsverket i Gamelby, i samarbete med KTH sedan hösten 2014 tagit fram en analys av hur ett framtida gårdsbaserat biogassystem kan se ut och samtidigt vara mer energioptimalt än dagens motsvarigheter.

  4. 4. Systematic comparison of the relative accuracy of vegetation surveys and soil DNA metabarcoding : Assessing plant biodiversity at different spatial scales

    Master-uppsats, Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Författare :Kimmo Kumpula; [2020]
    Nyckelord :DNA metabarcoding; biodiversity assessment; environmental DNA; high-throughput sequencing; subarctic;

    Sammanfattning : Analysis of soil-derived DNA has been shown to minimize problems seen during traditional vegetation surveys, e.g. by matching the eDNA to a reference database for taxonomic identification rather than relying solely on taxonomic expertise. However, it has been debated to what extent and how accurately eDNA acts as a proxy for biodiversity. LÄS MER

  5. 5. Performance Indicators for Smart Grids : An analysis of indicators that measure and evaluate smart grids

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik; Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Ishak Busuladzic; Marcus Tjäder; [2020]
    Nyckelord :Performance Indicators; Swedish Energy Markets Inspectorate; Electric Vehicle; Photovoltaic; Energy storage; Distributed electricity grid; Demand response; Smart grid; Monte-Carlo simulation; Renewable Energy;

    Sammanfattning : Sweden has developed ambitious goals regarding energy and climate politics. One major goal is to change the entire electricity production from fossil fuels to sustainable energy sources, this will contribute to Sweden being one of the first countries in the world with non-fossil fuel in the electricity sector.
