Fast Planning and Execution of Railroad Projects - Approaching the optimal duration
(Master thesis, 2017)The purpose of the research was to find out under what conditions fast planning and/or execution is profitable for BaneNor s projects. To do this, methods for fast planning and execution, and how they may affect the duration ... -
Fast Pressure Control in Managed Pressure Drilling
(Master thesis, 2014)In drilling operations, it is of great importance to efficiently and safely control the pressure in the well. To avoid possible damage to the reservoir, equipment, personnel and the environment, the pressure in the well ... -
Fast pricing of barrier options with NIG dynamics
(Master thesis, 2008)We show how we can price different barrier options very fast and accurately using numerical path integration. We will assume the underlying stock follow a NIG process. -
Fast protection against islanding and unwanted tripping of distributed generation caused by ground faults
(Chapter, 2017)Ground faults (GF) in a feeder with interconnected distributed generation (DG) might lead to overvoltages in healthy phases even after feeder disconnection from a substation, obstacles for reclosing schemes, and safety ... -
Fast Reservoir Characterization and Development of a Field Case Study with Real Production and 4D Seismic Data
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:267, Doctoral thesis, 2012)The primary goal of this PhD is to provide methods for continuous and fast optimization and updating of reservoir simulation models (i.e. history matching and associated forecast) based on production data, 4D seismic data ... -
Fast Seeded Region Growing in a 3D Grid
(Master thesis, 2011)The purpose of this thesis was to examine ways to adapt common 2D segmentation techniques to work with 3D grids. The focus of the thesis became how to automate and improve the performance of region growing in 3D grids. ... -
A fast semi-analytical method for propagating leaky Lamb wavefields
(Chapter, 2021)A fast method is presented for calculating the wavefields from initialized leaky Lamb waves on plates immersed in sufficiently light fluids. The method works by precomputing the dispersion relation and attenuation, and ... -
Fast Sensitivity-Based Nonlinear Economic Model Predictive Control with Degenerate NLP
(Journal article; Peer reviewed, 2018)We present a fast sensitivity-based nonlinear model predictive control (NMPC) algorithm, that can handle non-unique multipliers in the discretized dynamic optimization problem. Non-unique multipliers may arise, for example ... -
Fast Spatial Multi-level Models for Small Area Estimation
(Master thesis, 2023)Det foreslås en utvidelse av Besag-York-Mollié (BYM)-modellen som kan ta hensyn til romlig variasjon på flere nivåer. Multi-level modellen presenteres som en alternativ metode for nøyaktig estimering av demografiske data ... -
