  • Kersting, Magdalena; Steier, Rolf (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)
    According to general relativity (GR), we live in a four-dimensional curved universe. Since the human mind cannot visualize those four dimensions, a popular analogy compares the universe to a two-dimensional rubber sheet ...
  • Bjørhovde, Ingunn (Master thesis / Hovedoppgave, 2006)
    Samandrag Humane celler sin respons på stråling endrar seg med varierande doseratar. I denne oppgåva har to humane cellelinjer vorte bestrålte med ultralåge doseratar for å kartleggje effekten av strålinga ved bestrålingstider ...
  • Huseby, Morten (Master thesis / Masteroppgave, 2011)
    This thesis explores the possibility of a self sustained and service free Underwater Acoustic Sensor Network (UASN). The network nodes are installed along a subsea three phase High Voltage Alternating Current (HVAC) power ...
  • Abie, Sisay Mebre (Master thesis / Masteroppgave, 2014)
    The overall aim of the studies in this thesis is to investigate the universality nature of the conductivity of biological materials and the conduction mechanism using impedance spectroscopy measurement. Universality is a ...
  • Olsen, Kristian Stølevik; Limseth, Henrik Sverre; Lutken, Carsten Andrew (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We analyze experimental quantum Hall data from a wide range of different materials, including semiconducting heterojunctions, thin films, surface layers, graphene, mercury telluride, bismuth antimonide, and black phosphorus. ...
  • Teslyk, Maksym; Zabrodin, Evgeny; Bravina, Larissa (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)
    We apply the idea of the Unruh effect to the description of particle production in relativistic heavy ion collisions. Because the full information about all particles is needed, we employ the spectra of hadrons generated ...

    An enhanced probability for low-energy γ-emission (upbend, Eγ < 3 MeV) at high excitation energies has been observed for several light and medium-mass nuclei close to the valley of stability. Also the M1 scissors mode seen ...
  • Killingland, Live Karine Næss (Master thesis / Masteroppgave, 2015)
    The upconverting material of β-NaYF4:Yb,Er powder has been successfully made by a solvothermal syntheses method. The morphology of the main sample is hexagonal rods of about 1.2 µm in length. The samples show visible green ...
  • Langbach, Erlend (Master thesis / Masteroppgave, 2006)
    Denne oppgaven tar for seg design og implementasjon av et automatisert system for nøyaktig posisjonering av en hydrofon på grunt vann. Dette er viktig når lydfeltet utsendt fra et horisontalt skutt ekkolodd skal kartlegges. ...
  • Skumsvoll, Knut Salamon (Master thesis / Masteroppgave, 2008)
    1.0 Sammendrag Under arbeid med prosjektet har jeg som innledende delprosjekt arbeidet med analoge kretsløsninger, herunder likeretting og omhylningskurve av ekkosignal. Konklusjon og erfaring fra innledende prosjekt vil ...
  • Vinje, Asbjørn (Master thesis / Masteroppgave, 2017)
    Denne masteroppgaven beskriver prosessen rundt design, konstruksjon og testing av en ROV (Remote Operated Vehicle). ROV-en skal kunne benyttes som et verktøy for biologer og andre som utvikler hydroakustiske målemetoder. ...
  • Karset, Inger Helene Hafsahl (Master thesis / Masteroppgave, 2013)
    Modellsimuleringer har blitt benyttet til å studere hvordan bakkens refleksjon og skyers optiske tykkelse, hver for seg og samlet, påvirker UV-strålingen ved bakken. Tilpasninger på formen til summen av en geometrisk, ...
  • Mæland, Kenneth (Master thesis / Masteroppgave, 2014)
    With system on chip (SoC) gaining popularity in RF-applications, the need for UWB LNAs with an acceptable area and power consumption has increased. An amplifier topology with promising wideband results is the distributed ...
  • Horsdal, Mats (Doctoral thesis / Doktoravhandling, 2008)
    The present work is a study of the relationship between a quantum Hall system and its one-dimensional representation. The standard theory, which is based on general arguments, predicts that the edge of the quantum Hall ...
  • Guttormsen, Magne Sveen; Larsen, Ann-Cecilie; Görgen, Andreas; Renstrøm, Therese; Siem, Sunniva; Tornyi, Tamas Gabor; Tveten, Gry Merete (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)
    We analyze primary γ-ray spectra of the odd-odd 238Np nucleus extracted from 237Npðd; pγÞ238Np coincidence data measured at the Oslo Cyclotron Laboratory. The primary γ spectra cover an excitationenergy region of 0 ≤ Ei ≤ ...
