Dynamic modeling, simulation, and testing of a marine DC hybrid power system
(Peer reviewed; Journal article, 2020)The hybridization of power systems offers the low-emission and energy-efficient marine vessels. However, it increases the complexity of the power system. Design, analysis, control, and optimization of such a sophisticated ... -
Dynamic Modeling, Stability Analysis and Power Management of Shipboard DC Hybrid Power Systems
(Journal article; Peer reviewed, 2021)This paper proposes a framework for the stability analysis and control testing of marine hybrid power systems with DC power architecture. The dynamics of such active systems are increasingly influenced by interactive modes ... -
Dynamic Modelling and Analysis of Three Floating Wind Turbine Concepts with Vertical Axis Rotor
(Proceedings of the twenty-fifth International Ocean and Polar Engineering Conference;ISOPE 2015, Chapter, 2015)Recently there is an increasing interest in the development of offshore floating vertical axis wind turbines (FVAWTs). A FVAWT mounted on a semi-submersible has been proposed by several researchers, and a FVAWT with a spar ... -
Dynamic modelling and force analysis of a knuckle boom crane using screw theory
(Journal article; Peer reviewed, 2018)This article presents a method for determination of dynamic reaction forces in knuckle boom cranes. The method is based on the dynamic modelling procedure, which is an extension of Kane’s equations of motion. An efficient ... -
Dynamic modelling and simulation of the Graz Cycle for a renewable energy system
(Peer reviewed; Journal article, 2024)Critical atmospheric carbon dioxide levels and, in response, an increasing shift toward variable renewable energy sources causes the need of transient operation for thermal power plants coupled with carbon capture and ... -
Dynamic modelling and validation of an air‐to‐water reversible R744 heat pump for high energy demand buildings
(Peer reviewed; Journal article, 2021)This paper presents a reversible heat pump based on CO2 as the refrigerant, able to provide heating, cooling, and domestic hot water to high energy demand buildings. The unit was developed and tested under the EU H2020 ... -

Dynamic Modelling of Fuel Cell Systems for Electric Propulsion
(Chapter, 2021)In this paper, a dynamic model is developed for hybrid electric powertrains with fuel cell and batteries. The hybrid powertrain is considered mainly for marine propulsion with dynamic load, although the study can be ... -
Dynamic modelling of local low-temperature heating grids: A case study for Norway
(Journal article; Peer reviewed, 2017)Today's district heating (DH) networks in Norway are 2nd and 3rd generation systems, with supply temperatures ranging from 80 to 120 °C. In new developments, it is desirable to shift to 4th generation, low-temperature ... -
Dynamic modelling of the thermal response enhanced by sloshing in marine LNG fuel tanks
(Journal article; Peer reviewed, 2018)This paper investigates the thermal response in marine liquefied natural gas (LNG) fuel tanks by experiments and modelling. The aim of this work is to develop phenomenological models that can predict the rapid pressure ... -
Dynamic Models of Fixed Capital Stocks and Their Application in Industrial Ecology
(Journal article; Peer reviewed, 2014)Industrial assets or fixed capital stocks are at the core of the transition to a low-carbon economy. They represent substantial accumulations of capital, bulk materials, and critical metals. Their lifetime determines the ... -
Dynamic multi-agent dc-bus reconfiguration in modular motor drives with a stacked polyphase bridge converter
(Journal article; Peer reviewed, 2023)A stacked polyphase bridge converter consists of multiple standard, three-phase two-level voltage source inverters connected in series to the same dc voltage source. The authors present a decentralised and dynamic dc-bus ... -
Dynamic networks of psychological symptoms, impairment, substance use, and social support: The evolution of psychopathology among emerging adults
(Peer reviewed; Journal article, 2022)Background Subthreshold/attenuated syndromes are established precursors of full-threshold mood and psychotic disorders. Less is known about the individual symptoms that may precede the development of subthreshold syndromes ... -
Dynamic Obstacle Avoidance for Nonholonomic Vehicles using Collision Cones: Theory and Experiments *
(Chapter, 2023)Obstacle avoidance is a critical part in the control of autonomous vehicles. This paper proposes an obstacle avoidance algorithm based on the computationally advantageous collision cone concept, for unicycles which may be ... -
The dynamic of stepwise migrations of Nepalese high-skilled migrants via the Middle East
(Peer reviewed; Journal article, 2023)This article explores the experiences of Nepalese highly skilled migrants who use temporary migration to the Gulf region as a stepping-stone to further migration to developed countries outside the region. Furthermore, we ... -
Dynamic optimization of control setpoints for an integrated heating and cooling system with thermal energy storages
(Journal article; Peer reviewed, 2019)Energy systems for buildings and neighborhoods are expected to become more complex and flexible. Advanced control strategies are required to exploit the full potential of this flexibility and are especially important for ... -
Dynamic optimization of railway catenary system by turning unwanted lumped-mass into tuned-mass
