    • Na lidar measurements during the ECOMA/Geminids campaign with focus on Na peak density and temperature 

      Østerpart, Jørgen Olai Kristensen (Master thesis; Mastergradsoppgave, 2011-02)
      Using a resonance lidar, atomic Na (sodium) can be observed in the 80-110 km altitude range of the atmosphere. Na belongs to the alkali metal group and is highly reactive, so one could expect that it would quickly react ...
    • Natural variability of benthic foraminiferal assemblages and metal concentrations during the last 150 years in the Ingøydjupet trough, SW Barents Sea. 

      Dijkstra, Noortje; Junttila, Juho; Husum, Katrine; Carroll, JoLynn; Hald, Morten (Journal article; Tidsskriftartikkel, 2015-12)
      While today the SW Barents Sea is a relatively un-impacted and uncontaminated area, industrial activities related to the petroleum industry are projected to increase in the coming decades. This makes the area a valuable ...
    • The nature of the gas-hydrate/free gas transition zone at the base of the hydrate-stability zone from high-resolution 3D seismic data 

      Bjørnøy, Kirsti (Master thesis; Mastergradsoppgave, 2015-01-26)
      Geophysical evidence of a prominent BSR at Vestnesa Ridge and north to the northern flank of the Storegga slide escarpment infer that gas hydrates are ubiquitous within these regions. A wide range of fluid flow structures ...
    • Nature reserves as a bioeconomic management tool. A simplified modeling approach 

      Flåten, Ola; Mjølhus, Einar (Working paper; Arbeidsnotat, 2006-02)
      This paper demonstrates analytically how a nature reserve may protect the total population, realize maximum sustainable yield (MSY), maximum economic yield (MEY) and consumer surplus (CS) and how this depends on biological ...
    • Naturvitenskapens grunnlag og begrensning. Seminarrapport 

      Thorvaldsen, Steinar (Research report; Forskningsrapport, 1979)
      Foredrag av Arthur E. Wilder-Smith og Udo Middelmann holdt ved NTH i 1979
    • NB-FEB : an easy-to-use and scalable universal synchronization primitive for parallel programming 

      Tsigas, Philippas; Ha, Hoai Phuong; Anshus, Otto J. (Research report; Forskningsrapport, 2008-10)
      This paper addresses the problem of universal synchronization primitives that can support scalable thread synchronization for large-scale many-core architectures. The universal synchronization primitives that have been ...
    • Network analysis of geomagnetic substorms using the SuperMAG database of ground-based magnetometer stations 

      Dods, Joe; Chapman, Sandra; Gjerløv, Jesper (Journal article; Tidsskriftartikkel; Peer reviewed, 2015-09-26)
      The overall morphology and dynamics of magnetospheric substorms is well established in terms of the observed qualitative auroral features seen in ground-based magnetometers. This paper focuses on the quantitative ...
    • A new fluorous-tagged porphyrinoid 

      Larsen, Simon (Master thesis; Mastergradsoppgave, 2012-08-16)
      The field of corrole chemistry has flourished over the past decade. Simple and high-yielding procedures have made the corrole ligand readily available, and several procedures on how to functionalize and otherwise modify ...
    • Nexans Tracking System. An indoor positioning system using Bluetooth Low Energy 

      Holm, Ragnhild Kosmo (Master thesis; Mastergradsoppgave, 2015-06-01)
      Nexans Rognan is a cable manufacturer located in Nordland County. Each new cable order have a set of requirements provided by the customer. The cable specifications change in terms of characteristics of fibre optical ...
    • NFC Prototype Bonanza 

      Holmstad, Øyvind; Kreutzer, Tor (Research report; Forskningsrapport, 2011)
      This report presents the results of the research conducted by Tor Kreutzer and Ø yvind Holmstad during the summer of 2011 at the University of Troms ø. The goal of the project was to gain practical experience with Near ...
    • Nijenhuis tensors in pseudoholomorphic curves neighborhoods 

      Kruglikov, Boris (Working paper; Arbeidsnotat, 2000)
      In this paper we consider the normal forms of almost complex structures in a neighborhood of pseudoholomorphic curve. We define normal bundles of such curves and study the properties of linear bundle almost complex ...
    • Non-Gaussian Clustering of SAR images for Glacier Change Detection 

      Eltoft, Torbjørn; Akbari, Vahid; Doulgeris, Anthony Paul (Conference object; Konferansebidrag, 2010)
    • Non-Gaussian statistical analysis of polarimetric synthetic aperture radar images 

      Doulgeris, Anthony Paul (Doctoral thesis; Doktorgradsavhandling, 2011-02-18)
      This thesis describes general methods to analyse polarimetric synthetic aperture radar images, with the primary application of unsupervised image segmentation. The fundamental physics of electromagnetic scattering from ...
    • Nordlys i atmosfæren 

      Harang, Ove (Journal article; Tidsskriftartikkel, 1980)
      Nordlyset er lys i atmosfæren som skyldes nedbør av energirike partikler - særlig elektroner, og de former og bevegelser vi ser i nordlyset skyldes variasjoner i denne atmosfæren. Når energirike elektroner nærmer seg jorden ...
    • Nordlys i verdensrommet 

      Havnes, Ove (Journal article; Tidsskriftartikkel, 1980)
      Vi vil ikke her gå inn i nordlyset som vi kjenner det fra jorden, men kort omtale andre steder i verdensrommet hvor vi har observert nordlyslignende fenomen eller hvor vi kan vente å finne beslektede fenomen.
    • Nordlysets årsak 

      Leer, Egil (Journal article; Tidsskriftartikkel, 1980)
      Nordlys dannes av gass og strømmer ut fra sola. Denne solvinden stoppes av jordas magnetfelt, og energien i vinden fra sola overføres til negative og positive ladede partikler (elektroner og protoner) som skytes ned fra ...
    • Nordlysobservatoriet : historie og erindringer 

      Larsen, Reidulv; Berger, Steinar (Book; Bok, 2000-03)
      Reidulv Larsen og Steinar Berger tilbragte begge det meste av sitt yrkesaktive liv på Nordlysobservatoriet, fra 1940-tallet og fram mot 1990. Gjennom et så langt tidsrom oppsamles et betydelig forråd av kunnskap om ...
    • Nordlysobservatoriet gjennom 50 år 

      Holt, Olav (Journal article; Tidsskriftartikkel, 1980)
      De mange forsøk på å beskrive og forklare nordlyset som en finner i eldre litteratur vitner om lange tradisjoner for denne forskningen i vårt land. Norge ble av mange oppfattet som "Nordlysets Fædreneland" som biskop ...
    • Nordlysobservatoriet i dag
