  1. 1. The low-lying zeros of L-functions associated to non-Galois cubic fields

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Victor Ahlquist; [2023-02-13]
    Nyckelord :Mathematics; number theory; cubic fields; L-functions; low-lying zeros; onelevel density; two-level density; phase transition.;

    Sammanfattning : We study the low-lying zeros of Artin L-functions associated to non-Galois cubic number fields through their one- and two-level densities. In particular, we find new precise estimates for the two-level density with a power-saving error term. LÄS MER

  3. 2. FRÅN UTSÄTTNING AV ÖRINGROM TILL ÅRSYNGEL : EFFEKTER AV UTSÄTTNINGSMETODIK OCH INTRASPECIFIKA INTERAKTIONER

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

    Författare :David Rode; [2023]
    Nyckelord :;

    Sammanfattning : Egg stocking is a common method of re-establishing brown trout (Salmo trutta) populations, while the outcomes have been shown to give different results depending on variations in methods and locations. More recently, the dispersal of yearlings has been studied, but research on intraspecific interactions after egg stocking and the optimal number of eggs stocked are less studied. LÄS MER

  4. 3. Brunifiering av akvatiska ekosystem: En experimentell studie som undersöker tröskelvärde för predator- och bytesförhållande vid en gradient från klart till brunt vatten

    Kandidat-uppsats, Lunds universitet/Centrum för miljö- och klimatvetenskap (CEC)

    Författare :Erik Nilsson; [2023]
    Nyckelord :Brunifiering; tröskelvärde; födointag; predator- och bytesförhållande; Earth and Environmental Sciences;

    Sammanfattning : Browning of water has increased over the last couple of decades on the northern hemisphere. Research show that possible drivers for this change are land use change, climate change, increased precipitation and increased temperatures. LÄS MER

  5. 4. A quantitative analysis of plume gas distributions from different detection studies on Europa

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

    Författare :Anujan Ranganathan; [2023]
    Nyckelord :Europa; Water; Plume distribution; Surface Density; Column Density; Total number of molecules; Europa; Vatten; Plym Distribution; Ytdensitet; Kolumndensitet; Total mängd molekyler;

    Sammanfattning : The search for water has been vital in our solar system as water indicates a potential for life. The search has been extended to satellites orbiting the outer planets. It has already been proven that water exists on Saturn’s moon, Enceladus, where the spacecraft Cassini did a flyby through a water plume. LÄS MER

  7. 5. Exogenous Fault Detection in Aerial Swarms of UAVs

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Maja Westberg; [2023]
    Nyckelord :Exogenous Fault Detection; Local Outlier Factor; Aerial Swarm; Unmanned Aerial Vehicle; Behavioral Feature Vector; Outlier Detection; Cluster Analysis; Exogen Feldetektering; Local Outlier Factor; Drönarsvärm; Obemannad Drönare; Beteendevektor; Avvikelse-Analys; Kluster-Analys;

    Sammanfattning : In this thesis, the main focus is to formulate and test a suitable model forexogenous fault detection in swarms containing unmanned aerial vehicles(UAVs), which are aerial autonomous systems. FOI Swedish DefenseResearch Agency provided the thesis project and research question. LÄS MER
