  1. 6. A model for heterogenic catalytic conversion of carbon dioxide to methanol

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Elin Johannesson; [2020]
    Nyckelord :Carbon dioxide; methanol; heterogeneous catalysis; zinc oxide; computational chemistry; density functional theory;

    Sammanfattning : Since our society became industrialised, the levels of carbon dioxide in our atmosphere have been steadily rising, to the point where it in early 2020 at is 413 ppm. The high concentration is causing several troubling effects worldwide because of the increase in mean temperature that it creates, which causes longer draughts, more severe floods, and rising seawater levels to name a few.

  3. 7. Parallel Minimum Cuts : An improved CREW PRAM algorithm

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Andrés López Martínez; [2020]
    Nyckelord :;

    Sammanfattning : This thesis considers the minimum cut problem in undirected, weighted graphs. We present a simple randomized CREW PRAM algorithm to find the minimum cut in a graph G with n nodes and m edges, based on Karger’s celebrated randomized near-linear time min-cut algorithm [STOC’96].

  4. 8. Discussions on Dai-Freed Anomalies

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Huaiyu Li; [2019]
    Nyckelord :Anomaly; Quantum Fields Theory; Dai-Freed Theorem; Topology;

    Sammanfattning : In both field theories of high energy physics and field theories of condensed matter theories anomalies have been imposing constraints and bringing up new theories. While the perturbational and local anomalies from triangle diagrams are well-developed, we follow and review two works leading to non-perturbational global anomalies both related with Atiyah-Patogi-Sieger (APS) index theorem.

  5. 9. The development of a foiling trailer for transport of the AUV62-AT

    Master-uppsats, KTH/Marina system

    Författare :Simon Källerfelt Korall; [2019]
    Nyckelord :;

    Sammanfattning : The Swedish Navy recently presented a need to find new ways to transport autonomous underwater vehicles, AUVs, at high speed to and from mission areas. Following this, an investigation has been made into the development of a foiling trailer: a contraption that, when towed behind a small motorboat, will raise the AUV out of the water. LÄS MER

  7. 10. Från deltagande till delaktighet inom övervikt- och fetmaprevention riktad till barn : -En scopingstudie

    Master-uppsats, Högskolan i Halmstad/Akademin för hälsa och välfärd

    Författare :Lina Hagstrand; [2019]
    Nyckelord :Children; intervention; obesity prevention; participatory research; scoping review; Barn; deltagarbaserad forskning; fetmaprevention; intervention; scopingstudie;

    Sammanfattning : Förekomsten av övervikt och fetma hos barn ökar i världen trots insatser. Studier visar att förebyggande interventioner för barn och unga har blygsam effekt. Deltagarbaserad forskning har visat sig vara ett sätt att hitta hållbara lösningar inom hälsointerventioner. LÄS MER
