  1. 1. Deep learning of nonlinear development of unstable flame fronts

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ludvig Nobel; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The purpose of this study is to investigate Machine Learning methods and their ability to learn the development of nonlinear unstable flame fronts due to diffusive-thermal instabilities. This task is performed by first numerically computing long time-sequences of solutions to the chaotic partial differential equation named Kuramoto-Sivashinsky equation which models such instabilities in a flame front.

  3. 2. Teamarbete vid akuta situationer : Kvantitativ enkätstudie utifrån anestesisjuksköterskors inställning

    Magister-uppsats, Mälardalens universitet/Akademin för hälsa, vård och välfärd

    Författare :Charlotta Rundin; Erik Åhlén; [2023]
    Nyckelord :;

    Sammanfattning : Bakgrund: Välfungerande teamarbete beskrivs som en central del i upprätthållandet av patientsäkerheten. Akuta situationer är ofta kaotiska och då är det extra viktigt med välfungerande teamarbete. LÄS MER

  4. 3. Investigating a possible dearth of stars with zero angular momentum in the solar neighbourhood.

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation; Lunds universitet/Fysiska institutionen

    Författare :Aayush Desai; [2023]
    Nyckelord :Galaxy: disk; Galaxy: fundamental parameters; Galaxy: kinematics and dynamics; Galaxy: nucleus; solar neighborhood; stars: kinematics and dynamics; Physics and Astronomy;

    Sammanfattning : Background. Carlberg & Innanen (1987) first proposed the idea of measuring the solar re- flex velocity (the velocity of the Sun around the galactic centre), Vg,⊙, using the momenta of the stars in the solar neighbourhood. The proposal was a consequence of the work of L. LÄS MER

  5. 4. Tribonacci Cat Map : A discrete chaotic mapping with Tribonacci matrix

    Master-uppsats, Linnéuniversitetet/Institutionen för matematik (MA)

    Författare :Linnea Fransson; [2021]
    Nyckelord :Arnold s cat map; Tribonacci matrix; chaotic map; discrete dynamical system; linear recurrence sequence; Trisano period; 3D image encryption; colour encryption;

    Sammanfattning : Based on the generating matrix to the Tribonacci sequence, the Tribonacci cat map is a discrete chaotic dynamical system, similar to Arnold's discrete cat map, but on three dimensional space. In this thesis, this new mapping is introduced and the properties of its matrix are presented. LÄS MER

    Nyckelord :logistic function; Cantor set; generalised Cantor Set; fat Cantor set; fractals; fractal dimension; von Koch snowflake; Sierpinski arrowhead curve; Sierpinski carpet; Menger sponge; topological dimension; box dimension; exterior measure; Hausdorff measure; Hausdorff dimension; logistisk funktion; Cantormängd; fet Cantormängd; generaliserade Cantormängd; fraktaler‚; bråktalsdimension; Kochsnöfling; Sierpinskismatta; Sierpinskispilspetskurva; Mengers tvättsvamp; topologiska dimension; lådräkningsdimension; yttre mått; Hausdorffmått; Hausdorffdimension;

    Sammanfattning : Fractals is a relatively new mathematical topic which received thorough treatment only starting with 1960's. Fractals can be observed everywhere in nature and in day-to-day life. To give a few examples, common fractals are the spiral cactus, the romanesco broccoli, human brain and the outline of the Swedish map. LÄS MER
