Non-invasive Ultrasonic Inspection Through Steel Pipes Using the SURF Method
(Master thesis, 2014)The main objective of this thesis has been to study the possibility to establisha simulation tool for Second Order Ultrasonic Field (SURF) based on finiteelement modeling implemented in COMSOL Multiphysics. The SURF methodis ... -
Non-invasive waveform analysis for emergency triage via simulated hemorrhage: An experimental study using novel dynamic lower body negative pressure model
(Peer reviewed; Journal article, 2023)The extent to which advanced waveform analysis of non-invasive physiological signals can diagnose levels of hypovolemia remains insufficiently explored. The present study explores the discriminative ability of a deep ... -
Non-isothermal transport in cation-exchange membranes
(Master thesis, 2020)I denne masteroppgaven har seebeckeffekten blitt målt i ionebyttermembraner som er relevante for revers elektrodialyse (RED). Seebeckeffekten er elektrisk spenning som oppstår som følge av en temperaturgradient, og ... -
Non-isothermal transport of multi-phase fluids in porous media. Constitutive equations
(Journal article; Peer reviewed, 2019)We define a representative elementary volume of a porous medium in terms of lumped extensive variables, including properties of homogeneous phases, interfaces, and contact lines. Using the grand potential, we define the ... -
Non-isothermal transport of multi-phase fluids in porous media; The entropy production
(Journal article; Peer reviewed, 2018)We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Thermodynamic extensive variables on the ... -

Non-linear Bayesian inversion of seismic reflection amplitudes
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:146, Doctoral thesis, 2009)Seismic amplitudes can be used to assess subsurface information beyond a structural image through an amplitude-versus-angle (AVA) inversion. It is an application with challenging pre-processing and a difficult inversion ... -
Non-linear behaviour of insufficiently grouted post-tensioned concrete members
(Master thesis, 2021)Denne masteroppgaven har som mål å undersøke de konstruksjonstekniske effektene av manglende mørtel i etteroppspente betongkonstruksjoner. Dette ble gjort ved å gjennomføre ikke-lineære analyser i elementmetodeprogrammet ... -

Non-linear charge-based battery storage optimization model with bi-variate cubic spline constraints
(Peer reviewed; Journal article, 2020)Variable renewable generation demands increasing amount of flexible resources to balance the electric power system, and batteries stand out as a promising alternative. Battery models for optimization typically represent ... -
Non-Linear Clay Soil Model for Lateral Pipe-Soil Interaction
(Chapter; Peer reviewed, 2016)This paper describes implementation and application of nonlinear lateral soil models for pipeline lateral buckling analysis. Several lateral soil models have been developed in the past and the model developed by Verley is ... -
Non-linear control and digital twin modeling of the REMUS 100 AUV.
(Master thesis, 2020)Bruken av autonome undervannsfarkoster (AUV) i krevende, avsidesliggende miljøer involverer risikoen for kollisjoner og tap av fartøy. Koblet og ulineær dynamikk kombinert med underaktuering og usikker hydrodynamikk gjør ... -
Non-linear cross-sectional analysis of concrete shells
(Master thesis, 2021)Denne oppgaven omhandler å utvikle et dataprogram som iverksetter iterasjonsmetoden. Iterasjonsmetoden er en ikke-linear numerisk beregningsmetode som beregner kapasiteten i armerte betongskall. For at det skal være enkelt ... -
Non-linear dependency of wax appearance temperature on cooling rate
(Journal article, 2018)The Wax Appearance Temperature (WAT) is usually the first parameter to consider, when assessing whether paraffin wax contained in the crude oil can become an issue during production. As such, correct determination of the ... -
Non-Linear Economies of Scale in Food Production: The Case of Norwegian Bakeries
(Peer reviewed; Journal article, 2022)The bakery industry has a rich history. Its modern forms involve both manufacturing products and delivering them to customers. Both small bakers and large producers sell their products to the supermarket. The largest ... -
