Phased array radio system aided inertial navigation for unmanned aerial vehicles
(Journal article; Peer reviewed, 2018)Two of the major challenges with beyond visual line of sight (BVLOS) operations for unmanned aerial vehicles (UAVs) today are navigation and communication. This paper presents a solution that takes on both problems ... -
Phased-based Ranging for Navigation
(Master thesis, 2023)Det Globale Satelittnavigasjonsssystemet (GSNS) er sårbart for både bevisst og utilsiktet forstyrrelse på grunn av den svake signalstyrken. I kritiske scenarier blir det derfor nødvendig med en alternativ måte å finne ... -
Phasor Estimation based on Modified Recursive Prony
(Chapter, 2018)Synchronized Measurement Technology represented by Phasor Measurement Units (PMUs) is a sophisticated tool for power system monitoring and contributes to a more reliable and secure operation of the power systems. Phasor ... -

Photogrammetry for Drone Inspections: Introducing Advanced Path Planning for Automated Drone Operations
(Master thesis, 2018)Some ideas and procedures for realizing a system for automated inspection of structures have been presented throughout this thesis. The few presented results shows a reliable procedure for estimating normals in a coarse ... -
Physical controls on phytoplankton size structure, photophysiology and suspended particles in a Norwegian biological hotspot
(Peer reviewed; Journal article, 2019)The impact of the physical environment and phytoplankton size on particle types (zooplankton, biogenic matter or phytodetritus) in the water column is poorly understood. Here, we investigate how hydrography (e.g. water ... -
Physics guided machine learning using simplified theories
(Peer reviewed; Journal article, 2021)Recent applications of machine learning, in particular deep learning, motivate the need to address the generalizability of the statistical inference approaches in physical sciences. In this Letter, we introduce a modular ... -

(Master thesis, 2023)Physics-Informed Neural Networks (PINN) er nevrale nettverk som inkluderer kjente fysiske sammenhenger inn i treningsprosessen sin, slik at de kan modellere fysiske systemer effektivt, selv med begrenset tilgang til ... -
PI controller tuning based on historical data
(Master thesis, 2013)The effects on PI controller tuning related to information quality in input-output datahave been investigated. This is relevant as many industrial control systems store thiskind of data and it is desirable to be able to ... -
Pilot study of Early Meal Onset Detection from Abdominal Sounds
(Chapter, 2019)A typical artificial pancreas depends only on the continuous glucose monitoring (CGM) value for insulin dosing. However, both the insulin infusion and the glucose sensing are subject to time delays and slow dynamics. An ... -
Pipeline Liquid Control using Nonlinear MPC and OLGA: Optimal Utilization of Available Liquid Buffer Volume during Pipeline Transients
(Master thesis, 2007)Pipelines with multiphase flow will exhibit large and highly nonlinear liquid rates during transients caused by changes in production rate. This requires either a large separator (slug catcher) downstream, capable of ... -
