  1. 1. Lösning av diofantiska ekvationer med hjälp av Fourieranalys: En studie av Hardy-Littlewoods cirkelmetod

    Kandidat-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Hugo Bäckman; Tony Gromer; Rebecka Mårtensson; Elina Möller; [2023-11-28]
    Nyckelord :;

    Sammanfattning : I detta kandidatarbete i matematik vid Chalmers tekniska högskola och Göteborgs universitet studeras två applikationer av Hardy-Littlewoods cirkelmetod. Det redogörs för en förbättring på Warings problem för ett godtyckligt antal olika potenser. LÄS MER

  3. 2. Ocean rogue wave analysis for the development of safer navigation systems. : A Thesis submitted to the University of Gävle for the degree of Bachelor of Mathematics

    L3-uppsats, Högskolan i Gävle/Matematik

    Författare :Sergio Manzetti; [2023]
    Nyckelord :;

    Sammanfattning : Rogue waves are unexpectedly high waves of 2.5X the significant wave height and which occur in nearly all phases of nature, from  oceans, to fiber-optic cables and atmospheric air-masses. In the ocean, rogue waves pose a significant danger to shipping and fishing vessels and have been found to reach 27. LÄS MER

  4. 3. Evaluation of algorithms for accurate micro-doppler effects measurement in FMCW radar

    Master-uppsats, Linköpings universitet/Fysik, elektroteknik och matematik; Linköpings universitet/Tekniska fakulteten

    Författare :Morgan Agerstig Rosenqvist; [2023]
    Nyckelord :Radar; FMCW; micro-Doppler; RPM;

    Sammanfattning : Micro-Doppler effects are phenomena that occur because of micro-motion. A micro-motion is either a vibration, rotation, or acceleration which is small relative to the motion of the target. These effects can be used in order to characterize a target through their signature movement. LÄS MER

  5. 4. Particle Detection in Bone Marrow Using CNNs and Transformer Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Anna Källén; Marcus Williams; [2023]
    Nyckelord :Bone Marrow; Dark Field Microscopy; Fourier Ptychography; Machine Learning; Convolutional Neural Networks; Transformer Networks; Quantisation; Technology and Engineering;

    Sammanfattning : The critical role of hematological stem cells, concentrated in bone marrow, in disease diagnosis makes the detection of these cells an imperative task. The current process, however, is slow and heavily reliant on expert interpretation, underscoring the need for automation. LÄS MER

  7. 5. Gibbs Phenomenon for Fourier-Legendre Series

    Kandidat-uppsats, Karlstads universitet/Institutionen för matematik och datavetenskap (from 2013)

    Författare :Joakim Andersson Svendsen; [2023]
    Nyckelord :Fourier series; Fourier-Legendre series; Gibbs phenomenon;

    Sammanfattning : In this thesis, the main objective is to study the presence of Gibbs phenomenon and the Gibbs constant in Fourier-Legendre series. The occurrence of The Gibbs phenomenon is a well known consequence when approximating functions with Fourier series that have points of discontinuity. LÄS MER
