A Non-Compact Effective Impedance Model for Can-To-Can Acoustic Communication: Analysis and Optimization of Damping Mechanisms
(Peer reviewed; Journal article, 2021)Can-annular combustors can feature azimuthal instabilities even if the acoustic coupling between the individual cans is weak. Recently, various studies have focused on modeling the acoustic communication between adjacent ... -
Non-completion of secondary education and early disability in Norway: Geographic patterns, individual and community risks
(Journal article; Peer reviewed, 2018)Background School non-completion and early work disability is a great public health challenge in Norway, as in most western countries. This study aims to investigate how medically based disability pension (DP) among young ... -
Non-completion of upper secondary education and disability pensions in young adulthood: The matter of individual and contextual characteristics
(Doctoral theses at NTNU;2018:214, Doctoral thesis, 2018)Frafall fra videregående skole og uførepensjon i ung voksen alder: betydningen av individuelle og kontekstuelle faktorer Avhandlingen retter søkelyset på betydningen av individuelle sosiodemografiske faktorer og familie- ... -
Non-completion of upper secondary school among female and male young adults in an Arctic sociocultural context; the NAAHS study
(Journal article; Peer reviewed, 2016)Background: Education is closely associated with health. Non-completion of upper secondary school influences academic achievement, employment, income and personal well-being. The purpose of the study is to explore ... -
Non-Cooperative Power Control Game in D2D Underlying Networks with Variant System Conditions
(Journal article; Peer reviewed, 2019)In this paper, the problem of power control using a game theoretic approach based on sigmoid cost function is studied for device-to-device (D2D) communications underlying cellular networks. A non-cooperative game, where ... -
Non-destructive determination of kiwi quality parameters using hyperspectral imaging
(Bachelor thesis, 2021)Matsvinn er et stort problem i verden, og det er viktig å redusere det for å oppnå en bærekraftig fremtid. Kvalitetsanalyse av kiwier utføres for det meste ved destruktive metoder, noe som bidrar til matsvinn. Destruktive ... -
Non-Destructive Inspection of Polymer Composite Pipelines
(Master thesis, 2022)Rør laget av fiberforsterket komposittplast (FRP) har potensial til å erstatte metalliske i olje- og gassindustrien, grunnet deres fordelaktige egenskaper som lav vekt, høy styrke og motstand mot korrosjon. En stor hindringen ... -
Non-Destructive Surface Characterization of Wood Façade Materials and Wood Fungi by Attenuated Total Reflectance Fourier Transform Infrared Spectroscopy
(Doctoral theses at NTNU;2016:299, Doctoral thesis, 2016)Wood material is the dead xylem part of a tree that is being used for building construction, furniture, decorative items etc. Building façade is the outer envelope of a building. Wood façade materials are exposed against ... -
Non-destructive Test Methods for Corrosion Detection in Reinforced Concrete Structures
(Peer reviewed; Journal article, 2020)Several inspection methods can be used to assess the corrosion state of steel reinforcement in concrete. Especially for periodical field surveys and monitoring, non-destructive testing (NDT) methods are to be preferred as ... -
Non-Destructive Testing of Concrete
(Master thesis, 2021)Målinger av variasjonen i ultrasonisk lydhastighet i betong, som funksjon av påtrykt tøyning ble foretatt 17. Juni 2021, ved SINTEF formasjonsfysikk. Betongprøvene var plassert i en kompresjonsramme med kompresjon på 28 ... -
Non-disclosure of suicidal ideation in psychiatric inpatients: Rates and correlates
(Peer reviewed; Journal article, 2021)The study explored how common non-disclosure of suicidal ideation is in a sample of adult psychiatric inpatients (N = 171) plus associated patient characteristics. A large percentage (51.5%) withheld some information on ... -
Non-domestic building typologies - Systematic selection criteria for case studies for improved energy efficiency in management and use
(Master thesis, 2014)This master’s thesis highlights the importance of management and use in relation to energy efficiency in existing non-domestic buildings. The purpose of the master’s thesis is to study the energy efficiency of existing ... -
Non-elastic effects in static and dynamic rock stiffness
(Chapter, 2017)The static stiffness of a rock is generally smaller than its dynamic stiffness, which, for non-dispersive rocks, is due to a difference in strain amplitude in compaction tests (quasi-static) and wave-velocity measurements ... -
Non-equilibrium molecular dynamics simulations of the transient Ludwig-Soret effect in a binary Lennard-Jones/spline mixture
(Journal article, 2017)A binary isotope mixture of Lennard-Jones/spline particles at equilibrium was perturbed by a sudden change in the system's boundary temperatures. The system's response was determined by non-equilibrium molecular dynamics ... -
Non-equilibrium quantum effects in hybrid structures of ferromagnets and superconductors
(Master thesis, 2016)The quasiclassical theory of superconductivity is applied to diffusive nanowires connecting normal-metal and superconducting bulk materials. The diffusion equations for ferromagnetic junctions with spin-orbit coupling are ... -
