A non-intrusive parametric reduced order model for urban wind flow using deep learning and Grassmann manifold
(Peer reviewed; Journal article, 2021)In this study, we present a parametric non-intrusive reduced order modeling framework as a potential digital twin enabler for fluid flow related applications. The case study considered here involves building-induced flows ... -
Non-perfect channel estimation in OFDM-MIMO-based underwater communication
(Chapter, 2009)The main focus in this publication is on the mean square error of underwater acoustic channel estimators as function of the delay and Doppler spreads of the channel, and the effect this estimation error has on the bit error ... -
Noninvasive Transorbital Assessment of the Optic Nerve Sheath in Children: Relationship Between Optic Nerve Sheath Diameter, Deformability Index, and Intracranial Pressure
(Journal article; Peer reviewed, 2018)BACKGROUND: Measurement of optic nerve sheath diameter (ONSD) is a promising technique for noninvasive assessment of intracranial pressure (ICP), but has certain limitations. A recent study showed that the deformability ... -
Nonlinear deformation of tractography in ultrasound-guided low-grade gliomas resection
(Journal article; Peer reviewed, 2018)Purpose In brain tumor surgeries, maximum removal of cancerous tissue without compromising normal brain functions can improve the patient’s survival rate and therapeutic benefits. To achieve this, diffusion MRI and ... -
Nonlinear domain decomposition scheme for sequential fully implicit formulation of compositional multiphase flow
(Peer reviewed; Journal article, 2019)New sequential fully implicit (SFI) methods for compositional flow simulation have been recently investigated. These SFI schemes decouple the fully coupled problem into separate pressure and transport problems and have ... -
Nonlinear Observers for Integrated INS/GNSS Navigation – Implementation Aspects
(Peer reviewed, 2017)Navigation is a term with broad usage in everyday life and can mean the act of moving, moving through an unknown environment, ascertaining a craft's position, or even browsing on the Internet. Originally, the term meant ... -
Nonlinear Solver for Three-Phase Transport Problems Based on Approximate Trust Regions
(Journal article; Peer reviewed, 2017)Implicit transport solvers used in reservoir simulation can take longer time steps than explicit solvers, but for long time steps, the commonly used Newton-Raphson’s method will often fail to converge. The convergence ... -
NordTyre - Tyre/road noise testing on various road surfaces - State-of-the-Art
(SINTEF Rapport;, Research report, 2012)This report is the first deliverable of the NordFoU project NordTyre.The main purpose of the project is to establish scientific evidence of the tyre/road contribution to road traffic noise emission in the Nordic countries. ... -
Normalization of maritime accident data using AIS
(Journal article; Peer reviewed, 2019)The Automatic Identification System (AIS), fitted on most ships today, is primarily used for real time ship monitoring. This paper illustrates how stored AIS data can be used to construct activity data that can be used to ... -
NORTIM version 3.3. User Interface Documentation
(Research report, 2007)NORTIM, the program for calculation of aircraft noise propagation, has four main components: A calculation kernel, a project database, a master database, and a user interface. The latter is a tool where the user may combine ... -
Norwegian State of estate report as linked open data
(Journal article; Peer reviewed, 2017)This paper presents the Norwegian State of Estate (SoE) dataset containing data about real estates owned by the central government in Norway. The dataset is produced by integrating cross-domain government datasets including ... -
A novel hybrid analysis and modeling approach applied to aluminum electrolysis process
(Peer reviewed; Journal article, 2021)Aluminum electrolysis cells are characterized by harsh environments where several measurements have to be done manually. Due to the operational costs related to manual sampling, the sampling rates of these measurements are ... -
Novel NIR Transflection Measurements for Non-contact Core Temperature of processed Meat Products
(Chapter, 2010)A novel system for online measurement of core temperature in processed meat products is presented. The system allows near infrared (NIR) light to interact with the product to a depth of up to 2cm using noncontact optics. ... -
Nuancing the role of social skills-A longitudinal study of early maternal psychological distress and adolescent depressive symptoms
(Journal article; Peer reviewed, 2018)Background Social skills might play an important role for the relationship between maternal psychological distress and subsequent development of depressive symptoms. The majority perspective is that social skills is adaptive ... -
