  1. 1. Low-lying zeroes of L-functions attached to modular forms

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Alf Söderberg; [2024-03-22]
    Nyckelord :Number theory; L-functions; Modular forms; Newforms; Low-lying zeros; 1-level density; Density Conjecture; Ratios Conjecture.;

    Sammanfattning : We study the family of L-functions attached to Hecke newforms of weight k and level N and their low-lying zeroes. First, we recall the Density Conjecture of Katz and Sarnak and how it predicts the behaviour of the low-lying zeroes of any natural family of L-functions. LÄS MER

  3. 2. Microfluidic sorting of sperm for assisted reproduction - An evaluation of ZyMōt multi sperm separation device

    Kandidat-uppsats, Göteborgs universitet / Instiutionen för biologi och miljövetenskap

    Författare :Emma Olofsson; [2023-06-22]
    Nyckelord :Assisted reproduction technologies Spermatozoa DNA fragmentation Density-gra- dient centrifugation Microfluidics ZyMōt Multi;

    Sammanfattning : Infertility is a worldwide problem and the main reason for the use of assisted reproductive technol- ogy (ART). In-vitro fertilization (IVF) is one ART treatment normally used, where the fertilization of oocytes occurs in vitro. LÄS MER

  4. 3. 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

  5. 4. Primary Drivers of Sea Level Variability in the North – Baltic Sea Transition Using Machine Learning

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :David Ek; [2023-01-09]
    Nyckelord :;

    Sammanfattning : Global mean sea level is rising, however not uniformly. Regional deviations of sea surface height (SSH) are common due to local drivers, including surface winds, ocean density stratifications, vertical land- & crustal movements and more. LÄS MER

  7. 5. Battery profit optimization

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Ebba Helfer; [2023]
    Nyckelord :Battery; 2nd life battery; Ancillary services; BESS; energy storage system; Technology and Engineering;

    Sammanfattning : In the near future, a new market will form full of 2nd life batteries that are no longer suitable to use in electric vehicles. This since their capacity retention is too low after a few years of usage, as a consequence of two aging mechanisms; cycling aging and calendar aging. LÄS MER
