Performance assessment of K-out-of-N safety instrumented systems subject to cascading failures
(Peer reviewed; Journal article, 2021)Safety instrumented systems often employ redundancy to enhance the ability to detect and respond to hazardous events. The use of redundancy increases the fault tolerance to single failure but remains vulnerable in case of ... -
Performance Bounds for Tracking Multiple Objects using a Single UAV
(Chapter, 2017)In this paper we calculate probabilistic estimates for the size of an area a single unmanned aerial vehicle (UAV) can expect to monitor when tracking multiple objects. The objects are assumed to move according to a linear ... -
Performance Comparison of Backstepping-Based Adaptive Controllers for Marine Surface Vessels
(Chapter, 2016)This paper deals with the design and evaluation of three controllers based on backstepping and different adaptive control schemes, which are applied to the motion control of a nonlinear 3 degrees-of-freedom model of a ... -
Performance Comparison of Controllers with Fault-Dependent Control Allocation for UAVs
(Journal article; Peer reviewed, 2017)This paper combines fault-dependent control allocation with three different control schemes to obtain fault tolerance in the longitudinal control of unmanned aerial vehicles. The paper shows that fault-dependent control ... -
Performance evaluation of different Kalman filters for state estimation of lithium-ion batteries
(Master thesis, 2022)Litium-ion-batterier representerer en enorm industri og har vist seg å være en sentral teknologi for å redusere klimagasser. Ettersom elektrifiseringen av transportsektoren fortsetter å øke, vil de potensielle gevinstene ... -
Performing Dynamic Manipulation of a Rolling Object on the Butterfly Robot with Perturbation in System Parameters
(Master thesis, 2021)En av de vanskeligste aspektene ved ˚a reprodusere menneskelig atferd i robotikk er ˚a utføre ikke-prehensile (ikke-gripende) objektmanipulering. Dersom roboter skal kunne integreres i en menneskeskapt verden, m˚a de være ... -
A Persistent Sea-Going Platform for Robotic Fish Telemetry Using a Wave-Propelled USV: Technical Solution and Proof-of-Concept
(Peer reviewed; Journal article, 2022)Over the last few decades, acoustic fish telemetry has developed into a viable approach for remote monitoring of fish behaviour in the marine environment. Simultaneously, unmanned surface and underwater vehicles have found ... -
Petrel Software Usability Study: Using the Microsoft Kinect v2 for Workflow Execution
(Master thesis, 2015)The computer mouse has been one of the most commonly used interaction devices for a long time. This thesis set out to explore new interaction possibilities in regards to effectiveness, efficiency and satisfaction. The ... -
Petri nets for modelling and calculations
(Master thesis, 2014)A Petri net is a mathematical, graphical, executable technique for the specification, modeling and analysis of concurrent, discrete-event dynamic systems. Petri net is a directed bipartite graph, in which the nodes represent ... -
Petroleum production optimization - A static or dynamic problem?
(Journal article; Peer reviewed, 2018)This paper considers the upstream oil and gas domain, or more precisely the daily production optimization problem in which production engineers aim to utilize the production systems as efficiently as possible by for instance ... -
Ph.d.-utdanning innen ingeniørfag
(Journal article; Peer reviewed, 2013)Doktorgradsutdanning er en viktig del av samfunnsoppdraget til universitets- og høyskolesektoren. Dette har ført til en kraftig økning i antallet ph.d.-grader i Norge, og det har vært en tydelig dreining av ph.d.-utdanningen ... -
Phase Angle Feed-Forward Control for Improving the Power Reference Tracking of Virtual Synchronous Machines
(Peer reviewed; Journal article, 2023)A method for improving the power reference tracking capability of Virtual Synchronous Machines (VSM) by phase angle feed-forward (PAFF) control is proposed in this paper. The presented implementation includes compensation ... -
A phase-time-path-difference approach for online wave direction and wave number estimation from measured ship motions in zero and forward speed using a single inertial measurement unit
(Journal article; Peer reviewed, 2023)This study investigates the potential capability of a relatively new and unexplored signal-based approach for shipboard wave estimation. The approach uses the phase-time-path-differences (PTPDs) from an array of shipboard ... -
