Magnitude Adversarial Spectrum Search-based Black-box Attack against Image Classification
(Master thesis, 2022)De siste årene har forskning vist at dype nevrale nettverk som brukes i bildeklassifiseringssystemer er sårbare mot fiendtlige angrep. I denne oppgaven utformer vi et umålrettet søkeeffektivt beslutningsbasert svart-boks ... -
Magnitude Adversarial Spectrum Search-based Black-box Attack against Image Classification
(Chapter, 2022)Recent development has revealed that deep neural networks used in image classification systems are vulnerable to adversarial attacks. Thus, it is critical to understand the possible adversarial attacks to develop effective ... -
Magno: A Platform for Dyslexia Screening
(Master thesis, 2022)Dysleksi er ansett som en av de mest vanlige leseforstyrrelsene. Evnen til å oppdage dysleksi tidlig er kritisk for å kunne redusere de negative innvirkningene dysleksi kan ha. Det magnocellulære systemet virker å være ... -
Magno: An Application for Detection of Dyslexia - Dyslexia and Interface Design
(Master thesis, 2017)Dyslexia is a disability that has accumulated more and more attention over the latest years. Being able to detect dyslexia early on is vital for decreasing the negative effects dyslexia has on people diagnosed with this ... -
Magno: An Application for Detection of Dyslexia - From Native to Web App
(Master thesis, 2021)Dysleksi er en leseforstyrrelse som påvirker mange. Det magnocellulære systemet, ansvarlig for visuell bevegelsesoppfatning, synes svekket hos folk med dysleksi. En Java-applikasjon kalt Magno brukes til å teste individer ... -
Magno: An Application for Early Detection of Dyslexia - Implementing Role-Based Access Control and Enhancing Pupil Follow-Up
(Master thesis, 2023)Magno er et digitalt screeningsverktøy for dysleksi. Applikasjonens formål er å tilrettelegge for tidlig deteksjon av dysleksi, og dermed begrense de negative konsekvensene på enkeltpersoners akademiske prestasjoner og ... -

Magnon Condensation of Magnetic Insulators
(Master thesis, 2023)Bose-Einstein kondensasjon er et forskningsfelt som har fått økt oppmerksomhet etter at Ketterle et al. og Cornell et al., i 1995, fremstilte et kondensat for første gang. Begge gruppene laget kondensatet av reelle ... -
Magnon decay theory of Gilbert damping in metallic antiferromagnets
(Peer reviewed; Journal article, 2020)Gilbert damping is a key property governing magnetization dynamics in ordered magnets. We present a theoretical study of intrinsic Gilbert damping induced by magnon decay in antiferromagnetic metals through s−d exchange ... -
Magnon drag in a metal–insulating antiferromagnet bilayer
(Peer reviewed; Journal article, 2022)We study a bilayer structure consisting of an antiferromagnetic insulator and a normal metal. An electron current is driven in the normal metal with direction parallel to the interface between the materials. Due to interfacial ... -
Magnon Excitations of a Dzyaloshinskii-Moriya Coupled Insulating 2D Antiferromagnetic Skyrmion
(Master thesis, 2018)Motivated by recent experimental progress in realizing novel antiferromagnetic phases with state-of-the-art characteristics for memory storage and information processing, we study the magnon excitation spectra and eigenmodes ... -
Magnon Spin Current Induced by Triplet Cooper Pair Supercurrents
(Peer reviewed; Journal article, 2021)At the interface between a ferromagnetic insulator and a superconductor there is a coupling between the spins of the two materials. We show that when a supercurrent carried by triplet Cooper pairs flows through the ... -
Magnon-Mediated Indirect Exciton Condensation through Antiferromagnetic Insulators
(Journal article; Peer reviewed, 2019)Electrons and holes residing on the opposing sides of an insulating barrier and experiencing an attractive Coulomb interaction can spontaneously form a coherent state known as an indirect exciton condensate. We study a ... -
Magnon-mediated superconductivity and other collective phenomena in heterostructures of magnets and conductors
(Doctoral theses at NTNU;2022:269, Doctoral thesis, 2022)Sammendrag: Superledning fra magnetisme Når ulike typer materialer kobles sammen, kan deres egenskaper bli påvirket av hverandre. Spesielt i nærheten av overflaten mellom to ulike materialer, kan nye ting skje. ... -
Magnon-mediated superconductivity on the surface of a topological insulator
(Journal article; Peer reviewed, 2020)We study superconductivity on the surface of a topological insulator, mediated by magnetic fluctuations in an adjacent ferromagnetic or antiferromagnetic insulator. Superconductivity can arise from effective interactions ... -
Magnon-Mediated Superconductivity: Investigating the Emergence of Strong Topological Superconductivity Mediated by Magnons in a Coplanar, Non-Collinear Magnet
(Master thesis, 2023)Denne masteroppgaven undersøker hvorvidt topologisk superledning kan oppstå i et todimensjonalt system bestående av et normalmetall og en magnet med koplanær spinnfase. Vi bygger videre på arbeidet til Mæland og Sudbø [1], ... -
Magnon-polarons in cubic collinear antiferromagnets
(Peer reviewed; Journal article, 2019)We present a theoretical study of excitations formed by hybridization between magnons and phonons—magnon-polarons—in antiferromagnets. We first outline a general approach to determining which magnon and phonon modes can ... -
Magnus Expansion in Gauge Theories
(Master thesis, 2022)Noen uttrykk for løsningen på en ordinær differensiallikning utledes ved hjelp av en metode som innebærer Taylor-rekkeutvikling av vektorfeltet som definerer differensiallikningen. En generalisering av et kjent resultat ... -
Magnus the Chess Robot
(Master thesis, 2014)The goal of this thesis was to create a low-cost chess-playing robot to help progress the field of small-scale robotics and make it more available for personal use. To achieve this, methods for moving pieces on a chessboard ... -
