IR THERMOGRAPHY in Multiphysics Applications
(Conference object; Konferansebidrag, 2018)It is seen that Infrared (IR) thermography is becoming one of the very popular and effective methods in the industry as well as research and development sectors. IR thermography being a remote non-contact/non-destructive means of testing is perfectly suitable for tests in extreme environments. In addition, it is fast, reliable and detailed. Due to the advantages offered by IR thermography, it is ... -
IR Thermography of Steel Specimens undergoing Tensile Tests
(Conference object, 2018-12-13)In this work, the IR thermography was used to study the steel specimens (DIN 50125 Standard) undergoing the tensile tests. The tensile tests were performed using GUNT® Hamburg Universal Material Tester. The tensile specimens were clamped, and the test force was generated using a hand-operated hydraulic system. A dial gauge measured the elongation of the specimens. Using the WP 300.20 system for data ... -
Iron ore dust as a natural pigment in concrete with RCA for artwork application
(Chapter; Bokkapittel, 2022)A The innovative idea of utilization of iron ore dust (IODust), characterized by red hue typical for Narvik, came up during designing artwork for The Arctic University of Norway campus Narvik. The use of waste from iron ore production as a natural pigment was completed by partial replacement of natural aggregates (NA) by recycled concrete aggregates (RCA) to achieve a higher level of material ... -

Data collection at Tromsø Airport using simple and inexpensive equipment in order to capture images of different types of luggage will be described. Furthermore, a selection of three relevant ... -
Is Thorium a Viable Nuclear Fuel? [poster]
(Conference object; Konferansebidrag, 2018)Thorium was discovered in 1829 by the Norwegian mineralogist Morten Thrane Esmark and identified by the Swedish chemist Jöns Jacob Berzelius, who named it after Thor, the Norse god of thunder. Thorium is more abundant in nature than Uranium. It is fertile rather than fissile, and can only be used as a fuel in conjunction with a fissile material such as recycled plutonium. Thorium fuels can breed ... -
Isogeometric analysis using a tensor product blending spline construction
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-01)In this paper, we introduce a blending spline type construction into the isogeometric analysis. We consider a general algorithm for solving a number of boundary value problems, including heat equation, wave equation, linear elasticity, etc. The usage of blending spline construction in the isogeometric context mixes standard finite element and NURBS-based approaches while accumulating the benefits ... -
Isolation and Characterisation of Electrogenic Bacteria from Mud Samples
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-17)To develop efficient microbial fuel cell systems for green energy production using different waste products, establishing characterised bacterial consortia is necessary. In this study, bacteria with electrogenic potentials were isolated from mud samples and examined to determine biofilm-formation capacities and macromolecule degradation. Matrix-assisted laser desorption/ionization time-of-flight ... -
Kaibygging med betongelementer
(Master thesis; Mastergradsoppgave, 2017-06-08)"Sammendrag: Denne oppgaven omhandler bruk av betongelementer i kaikonstruksjoner.

Konstruksjonsmekaniske virkninger av raslaster. Dynamiske effekter av steinspranglaster på rasoverbygg. Nasjonale og internasjonale retningslinjer for bestemmelse av steinspranglaster. Dimensjonering av rasoverbygg
(Master thesis; Mastergradsoppgave, 2017-06-08)I mange tilfeller blir den dynamiske impulslasten fra steinsprang konvertert til en ekvivalent statisk last, på grunn av dempningsmaterialer som blir brukt som et beskyttelseslag på taket av overbygg. Dermed finnes mange ulike metoder for å konvertere den dynamiske lasten om til en ekvivalent statisk last på i ulike land, ut ifra geografiske begrensninger og materialegenskaper til beskyttelseslaget. ... -

Kritiske faktorer for effektivisering ved bygging av småhus. Hvordan kan småhusbransjen benytte digitalisering og industrialisering til å effektivisere boligbyggingen og redusere reklamasjoner?
(Master thesis; Mastergradsoppgave, 2019-06-26)Småhusbransjen er et segment i bygge- og anleggsbransjen, en bransje som mellom år 2000 og 2016 opplevde en nedgang i effektivitet og produktivitet på 10 prosent. Denne nedgangen skyldes mange forskjellige faktorer, men blant annet ulike byggemetoder, dårlig planlegging og logistikk har ført til at det tar lengre tid å bygge en bolig i dag. Økt fokus på effektivisering ved boligbygging er et populært ...
