  1. 16. Influence of climate change on Organism Abundance in the Kiruna Region, Northern Sweden: Insights from-long term high-quality DNA sequencing

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

    Författare :Anton Sandström; [2023]
    Nyckelord :Climate change; ecology; microorganisms; DNA-sequencing;

    Sammanfattning : This study investigates if the area around Kiruna, Northern Sweden has experienced large shifts in weather conditions and whether these have affected organism abundances. With a significant increase in global temperature and an increase in average temperature of 1. LÄS MER

  3. 17. Optical Detector for Microfluidics

    Magister-uppsats, Högskolan i Halmstad/Akademin för informationsteknologi

    Författare :Carlos Gómez Jiménez; Jaime Gómez Jiménez; [2022]
    Nyckelord :Serial crystallography; Microfluidic device; Optical detector; Particle counting;

    Sammanfattning : This project arose from the need to filter the sampled data and eliminate non-useful information in Serial Crystallography in Microfluidic Device (MFD)by using a portable optical detector placed around the channel. By testing sixteen different configurations, always using an LED as a source and a photodiode as a light sensor, changes in the channel due to the passage of air bubbles were detected. LÄS MER

    Kandidat-uppsats, KTH/Hållbar produktionsutveckling (ML)

    Författare :Kirandip Kaur; Tina Soltaniha; [2022]
    Nyckelord :Scania; energy saving; engineering industry; energy reduction; implementation plan; roadmap; Scania; energibesparing; verkstadsindustrin; energireducering; implementationsplan;

    Sammanfattning : År 2020 formulerade lastbilsproducenten Scania CV AB ett mål kring att minska sin energi-förbrukning med 25% till år 2025, med energiförbrukningen för år 2020 som baslinje. Effektiviseringen är nödvändig för att lastbilsproducenten ska kunna fortsätta bedriva ett hållbart och ansvarsfullt företagande. LÄS MER

  5. 19. Conductive interferences from multiple EC-motor installation : To measure and mitigate harmonics

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Signaler och system

    Författare :Victor Aitman; [2022]
    Nyckelord :harmonics; interharmonics; harmonic-mitigation; electromagnetic compability; EMC; övertoner; EC-motorer; störningar; övertonsreducering; elektromagnetiskt kompabilitet; EMC;

    Sammanfattning : Products produced by a Swedish company are requested to be investigated regarding their harmonic and inter-harmonic currents injected into the public supply system to comply with the Swedish standard SS-EN IEC 61000-3-2, Electromagnetic compatibility (EMC).    On behalf of Systemair Sweden AB, this bachelor thesis aims firstly to investigate if their product, PAFEC 4225 WH (Air Curtain), complies with standard SS-EN IEC 61000-3-2, and if not, what measures should be taken; and secondly to develop a low-cost instrument for the measurement of harmonics and inter-harmonics according to standard IEC 61000-4-7 related to the requirements on equipment used in standard SS-EN IEC 61000-3-2.

  7. 20. Viability, feasibility and Sustainability of emission reducing solutions for Nordic wood stoves: Testing and evaluation : Degree project for Master in mechanical engineering with focus on innovative and sustainable product development

    Uppsats för yrkesexamina på avancerad nivå, Blekinge Tekniska Högskola/Institutionen för maskinteknik

    Författare :Casper Berg; [2022]
    Nyckelord :Catalytic Filters; Variable filter deployment; Wood stove Emissions; Eco Design 2022; Reduced Emissions; Katalytiska filter; Varierande filter; Utsläpp från vedkaminer; Eco Design 2022; Reducerade utsläpp;

    Sammanfattning : As of 2022 the European Union introduced a new Eco Design legislation which states emission limits for stoves sold in the EU. There are already requirements on emissions, but as both legislation are to be harder and there is a higher interest in Eco friendly products, there is an interest to study different ways to reduce the emissions from wood stoves.
