Nonlinear Observers for Integrated INS/GNSS Navigation – Implementation Aspects
(Journal article, 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 Observers for Parametric Roll
(Master thesis, 2012)Parametric roll resonance is a dangerous resonance phenomenon affecting several kinds of ships, such as cruise ships, fishing vessels and container ships. In a worst case scenario parametric roll resonance may lead to roll ... -
Nonlinear optical response and structural properties of MBE-grown Fe:ZnS films
(Journal article; Peer reviewed, 2018)Fe-doped ZnS films of high optical quality were fabricated using vacuum vapor deposition. Preferential crystalline orientation and phase purity of the host ZnS films were increased by the addition of small amounts of Fe, ... -
Nonlinear optimization for Hyperparameter computation in Gaussian Processes machine learning
(Master thesis, 2019)Målene til denne masteroppgaven er: 1. Litteraturstudie på Gaussiske Prosesser (GP), Optimeringsteori og metoden av ulineære konjugerte gradienter (NCG). 2. Ny implementasjon av en GP-algoritme i programvare. 3. Analyse ... -
Nonlinear Output Constraints Handling for Production Optimization for Oil Reservoirs

Nonlinear phase unwinding
(Master thesis, 2018)We start of by studying Hardy spaces and Blaschke products. Then we look at a natural nonlinear analogue of Fourier series called the unwinding series. It is obtained through iterative Blaschke factorization and unwinds ... -
Nonlinear proper orthogonal decomposition for convection-dominated flows
(Peer reviewed; Journal article, 2021)Autoencoder techniques find increasingly common use in reduced order modeling as a means to create a latent space. This reduced order representation offers a modular data-driven modeling approach for nonlinear dynamical ... -
Nonlinear Pulse Propagation in Optical Fibers
(Master thesis, 2012)The project objective is to see how a pulse propagates along an optical fiber. This will take into account the linear effects of the fiber, as well as the nonlinear effects. Also be checked several commercial fiber types. ... -
Nonlinear State and Parameter Estimation using Discrete-Time Double Kalman Filter
(Journal article; Peer reviewed, 2017)Dealing with nonlinear dynamics in conventional estimation methods like the extended Kalman filter (EKF) is challenging, since they are not guaranteed to have global convergence, and their instability can arise by selecting ... -
A Nonlinear State Observer for the Bi-Hormonal Intraperitoneal Artificial Pancreas
(Chapter, 2022)Currently, continuous glucose monitoring sensors are used in the artificial pancreas to monitor blood glucose levels. However, insulin and glucagon concentrations in different parts of the body cannot be measured in ... -
Nonlinear stochastic dynamics and chaos by numerical path integration
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:18, Doctoral thesis, 2008)The numerical path integration method for solving stochastic differential equations is extended to solve systems up to six spatial dimensions, angular variables, and highly nonlinear systems - including systems that results ... -
Nonlinear Topics in the Bayesian Approach to Inverse Problems with Applications to Seismic Inversion
(Dr. ingeniøravhandling, 0809-103X; 2002:55, Doctoral thesis, 2002)Paper I considers piecewise affine inverse problems. This is a large group of nonlinear inverse problems. Problems that obey certain variational structures are of this type. In inverse problems it is frequently such that ... -
Nonlinear Two-Point Flux Approximation Schemes for Reservoir Simulation
(Master thesis, 2018)The main objective of this thesis has been to investigate some methods for simulating CO2 storage and hydrocarbon recovery on complex polyhedral grids, with main focus on the nonlinear two-point flux approximation method. ... -

Nonlocal nonlinear diffusion equations. Smoothing effects, Green functions, and functional inequalities
(Peer reviewed; Journal article, 2023)We establish boundedness estimates for solutions of generalized porous medium equations of the form where and is a linear, symmetric, and nonnegative operator. The wide class of operators we consider includes, but is not ... -
Nonparametric estimation in trend-renewal processes
(Master thesis, 2017)This thesis gives an introduction to stochastic modeling of repairable systems with failure and maintenance data, in particular the nonhomogeneous Poisson process and the trend-renewal process. It is studying kernel-based ... -

Norm attaining vectors and Hilbert points
(Journal article; Peer reviewed, 2024)Let H be a Hilbert space that can be embedded as a dense subspace of a Banach space X such that the norm of the embedding is equal to 1. We consider the following statements for a nonzero vector φ in H: (A) ∥φ∥X =∥φ∥H. (H) ... -
