A General Face Recognition System
(Master thesis, 2006)In this project a real-time face detection and recognition system has been discussed and implemented. The main focus has been on the detection process which is the first and most important step before starting with the ... -
A General Nonlinear Reservoir Simulator with the Full Approximation Scheme
(Master thesis, 2018)Simulation of multiphase flow and transport in porous rock formations gives rise to large systems of strongly coupled nonlinear equations. Solving these equations is computationally challenging because of orders of magnitude ... -
A heavy tailed statistical model applied in anti-collision calculations for petroleum wells
(Master thesis, 2008)Anti-collision calculations are done during the planning of a new petroleum well. These calculations are required in order to control the risk of having a well-collision, which is an unwanted event at any cost. The risk ... -
A Horizon Metadata Transformer for Multi-horizon Forecasting
(Master thesis, 2022)Multi-horizon time series forecasting poses fundamental challenges to machine learning and statistics with applications in many domains. In direct multi-horizon forecasting, the standard approach of neural nets is to either ... -
A Hybrid Metaheuristic for a Multi-Objective Mixed Capaciated General Routing Problem
(Master thesis, 2014)In this thesis, we have studied a bi-objective variant of the Mixed Capacitated General Routing Problem (MCGRP). The MCGRP is a generalization of other well known routing problems. It is defined on a mixed, weighted graph, ... -
A kink-model for gas simulation
(Master thesis, 2020)I denne masteroppgaven er vi interessert i Eulerligningene for kompressibel gass. En vanlig modell for å simulere gassflyt i rør er de isotermiske Eulerligningene. I denne oppgaven vil vi se på en modell som beskriver ... -
A Library for Computing with Trees and B-Series
(Master thesis, 2015)Unordered rooted trees and B-series can be used to analyze the properties of many one-step methods for autonomous ordinary differential equations. This thesis describes aspects of trees and B-series necessary to use them ... -
A mathematical model for calculating river hydrographs using high resolution digital elevation models
(Master thesis, 2017)Prediction of floods is important to prevent damage to human lives, build- ings or infrastructure, and we have developed a simulation model to address this. The model is a so-called distributed rainfall-runoff model, which ... -
A Memory-Tight Reduction for the Twin Hashed ElGamal
(Master thesis, 2022)I denne oppgaven ser vi på minnetetthet som en betingelse for sikkerhet i reduksjonsbaserte sikkerhetsbeviser. Minneeffektivitet er en viktig kompleksitetsparameter for black-box-reduksjoner når det aktuelle kryptografiske ... -
A Modular Implementation of the Traffic Equation Using the Cell Transmission Model
(Master thesis, 2019)Evnen til å simulere og modifisere et veinett i en virtuell simulering er et uvurderlig verktøy for å spare ressurser og tid for å identifisere den beste løsningen på et gitt problem. Målet med dette prosjektet var å skape ... -
A multiple-try Metropolis-Hastings algorithm with a tailored number of proposals
(Master thesis, 2019)Oppgaven presenterer en multiple-try Metropolis Hastings algoritme, som utvider målfordelingen til å sample en rettet asyklisk graf med et sett av noder og rettede kanter. Hver node er assosiert med en verdi som potensielt ... -
A new latent-variable statistical method for estimating the cost of phenotypic plasticity
(Master thesis, 2020)En ny latent variabel-metode for å oppdage kostnaden av plastisitet i en population har blitt testet ved hjelp av simuleringer. Individuell fitness ble modellert av en Poisson-fordeling med forventningsverdi i henhold til ... -
A Nonlinear Isogeometric Finite Element Analysis of a Wind Turbine Foil
(Master thesis, 2014)In the recent years, much attention has been given to the design of offshore wind turbines. Today, the largest wind turbine has a rotor diameter of 164m. The harsh environments expose the turbines to large forces from wind ... -
A Nonlinear Partial Differential Equation and Its Viscosity Solutions
(Master thesis, 2016)We study a nonlinear partial differential equation with Lipschitz continuous coefficient functions. Existence and uniqueness of viscosity solutions is proved by approximating with minimizers of variational integrals. The ... -
A Novel Profit Scoring Method for Classifying Credit Card Applications
