Mission planner for multiple AUVs: Verification procedures combining simulations and experiment
(Journal article; Peer reviewed, 2018)This paper presents a mission control system (MCS) for a cooperative system of LAUVs. The proposed method is part of a system for operating several AUVs on a joint mission. The system is run on software and hardware from ... -
Toward adaptive robotic sampling of phytoplankton in the coastal ocean
(Journal article; Peer reviewed, 2019)Currents, wind, bathymetry, and freshwater runoff are some of the factors that make coastal waters heterogeneous, patchy, and scientifically interesting—where it is challenging to resolve the spatiotemporal variation within ... -
On gradient-based optimization of jacket structures for offshore wind turbines
(Journal article; Peer reviewed, 2018)During the bidding or very early design phases of jacket structures for offshore wind turbines, there may be very limited information available on meteorological conditions, soil conditions, turbine specifications, etc. ... -
Thermal Gradients and Thermal Conductivity in PEM Fuel Cells, Compared to Li-Ion Batteries and Super Capacitors
(Journal article; Peer reviewed, 2018)The PEMFC has been developed into a very effective energy converter. That is, the PEMFC offers high power at the same energy efficiency range. This is because the cell potential remains constant while current density ... -
Effects of Flow Dynamics on Bank Erosion in Consecutive Meander Bends - A Field Study
(Doctoral theses at NTNU;2019:152, Doctoral thesis, 2019)The present dissertation describes the influence of natural alteration in the rivers flow regime on the change of morphology of a freely meandering river in Norway. It consists of a thesis and four attached research papers. ... -
A modelling framework to support environmental design in regulated rivers
(Doctoral theses at NTNU;2019:141, Doctoral thesis, 2019)Despite the fact that environmental design and mitigation measures in regulated rivers have been widely applied in the last decades, yet it is still a challenge to find a method that supports a sustainable balance between ... -
Modified Ginstling-Brounstein Model for Wet Precipitation Synthesis of Hydroxyapatite: Analytical and Experimental Study.
(Journal article; Peer reviewed, 2018)Purpose: Hydroxyapatite is the main mineral component in bones and teeth, thus being an important material in bone tissue engineering, e.g., for replacement and elimination of defects. Hydroxyapatite is widely used in ... -
Trade study to select best alternative for cable and pulley simulation for cranes on offshore vessels
(Journal article; Peer reviewed, 2019)Cranes on offshore vessels are subjected to crane dynamics, structural couplings to the vessel, and environmental influence by waves and currents. The recent trend has been to use larger cranes on smaller vessels, which ... -
Experimental and Theoretical Investigations on the Ship Resistance in Level Ice
(Doctoral theses at NTNU;2019:198, Doctoral thesis, 2019)The growing interest in Arctic transportation and field logistics leads to an increasing demand for ships with good ice breaking performance. The ice breaking performance of ships is usually defined by their ability to ... -
Entirely possible overruns: How people think and talk about probabilistic cost estimates

Data-Driven Beetle Antennae Search Algorithm for Electrical Power Modeling of a Combined Cycle Power Plant
(Journal article; Peer reviewed, 2019)Beetle Antennae Search (BAS) is a newly developed nature-inspired algorithm, which falls in the class of single-solution driven metaheuristic techniques. This algorithm mimics the searching behavior of the longhorn beetles ... -
Experimental and numerical studies related to failure of first-year ice ridges against fixed vertically sided structures
(Doctoral theses at NTNU;2019:192, Doctoral thesis, 2019) -
PRELIMINARY FLOOD RISK ANALYSIS FOR CLIMATE CHANGE SCENARIOS: THE CASE STUDY OF THE ORKLA RIVER SYSTEM
(Master thesis, 2018)Formålet med denne endelige masteroppgaven er å analysere flomrisiko i Orkla-elven, lokalisert i Sor Trondelag (Norge). Arbeidet dekker den nåværende situasjonen for å analysere fremover klimaendringene og analysere ... -
Critical Soft Factors for Optimum Performance of Maintenance Operations
(Journal article; Peer reviewed, 2019)Abstract: Over the past three decades, an increasing trend has been observed in research related to the consideration of human factors instead of solely based on the traditional aspects of project and operations management. ... -
Coupling Input‐Output Tables with Macro‐Life Cycle Assessment to Assess Worldwide Impacts of Biofuels Transport Policies
(Journal article; Peer reviewed, 2018)Many countries see biofuels as a replacement to fossil fuels to mitigate climate change. Nevertheless, some concerns remain about the overall benefits of biofuels policies. More comprehensive tools seem required to evaluate ... -
Assessment on the hydrogeological condition of an open pit mine based on piezometric measurements
(Journal article; Peer reviewed, 2019)Understanding groundwater and flow pattern behavior in a given mine site is generally based on accepted theory related to flow through porous granular media. The existence of discontinuities within the rock mass alters the ... -
Enabling Sequential Rupture for Lowering Atomistic Ice Adhesion
(Journal article; Peer reviewed, 2019)State-of-the-art passive icephobicity relies mainly on static parameters such as surface energy, coating elastic modulus, crack sizes and so on. Low ice adhesion resulting from dynamic de-icing process, for instance ice ... -
Investigations of Different Control Strategies for Heat Pump Systems in a Residential nZEB in the Nordic Climate
(Chapter, 2017)The paper investigates different control strategies for a ground source heat pump of a Norwegian residential zero emission building, with detailed dynamic simulations (here using IDA ICE). These rule-based controls aim at ... -
Modeling and Analysis of Motion Data from Dynamically Positioned Vessels for Sea State Estimation
(Chapter, 2019)Developing a reliable model to identify the sea state is significant for the autonomous ship. This paper introduces a novel deep neural network model (SeaStateNet) to estimate the sea state based on the ship motion data ... -
Data-driven surrogate assisted evolutionary optimization of hybrid powertrain for improved fuel economy and performance
(Journal article; Peer reviewed, 2019)This article presents an optimized series-parallel hybrid powertrain transformed from a conventional vehicle using an analytical approach without changing the original chassis. The proposed approach is based on a many-objective ...
