The impact of safety factors on decision-making in maritime navigation
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023)Approximately 85% of maritime accidents are accounted for by navigation accidents, caused by human errors such as mistakes in impropriate decision-making. Decision-making skills are the key to safe sailing. However, the assessment of decisionmaking based on objective measurements is rarely studied. This paper aims to assess the impact of safety factors on decision-making in maritime navigation. ... -
Investigation of Ice-PVC separation under Flexural Loading using FEM Analysis
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)This paper presents the FEM technique applied in the study of ice separation over a polyvinyl chloride (PVC) surface. A two layer model of ice and PVC is analysed theoretically using Euler-Bernoulli beam theory and the rule of mixtures. The physical samples are prepared by freezing ice over the PVC surfaces. The samples are tested experimentally in a four-point loading setup. The experimental results ... -
Multiphysics design optimization for aerospace applications: Case study on helicopter loading hanger
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014)This paper presents the Multiphysics technique applied in the design optimization of a loading hanger for an aerial crane. In this study, design optimization is applied on the geometric modelling of a part being used in an aerial crane operation. A set of dimensional and loading requirements are provided. Various geometric models are built using SolidWorks® Computer Aided Design (CAD) Package. In ... -
Multiphysics investigation of Ice Adhesion over PVC surface
(Conference object; Konferansebidrag, 2015-12-10)This work investigates the ice over a PVC (polyvinyl chloride also known as ‘PVC’) surface as a two-layer laminate model. In this study, ice was frozen over a PVC surface and allowed to adhere. The built samples were tested experimentally in a four-point loading setup. The experimental results contain strain data gathered through data acquisition system using LabView® software. The data was collected ... -
Multiphysicsbased Condition Monitoring of Composite Materials
(Conference object; Konferansebidrag, 2015-12-10)Composites are increasingly being used in products such as: automobiles, bridges, boats, drillships, offshore platforms, aircrafts and satellites. The increased usage of these composite materials and the fact that the conditions pertaining to their failure are not fully understood makes it imperative to develop condition monitoring systems for composite structures. <br>In this work, we present a ... -
Review of the Phenomenon of Ice Shedding from Wind Turbine Blades
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-29)Wind power is a sustainable source of energy. However, there are certain challenges to be overcome. One of the operational challenges is the phenomenon of ice shedding. Icing happens on wind turbine blades in cold regions. When ice grows to a certain size, it separates from the wind turbine blades resulting in the phenomenon of ice shedding. This phenomenon is of significantly dangerous for equipment ... -
Study of Acoustics Properties of SK One Component Polyurethane and its Application in Arctic Marine Structures
(Conference object; Konferansebidrag, 2016-12-08)Marine noise reduction tends to be challenging and requires a comprehensive engineering approach. The soundproofing materials for marine noise reduction are usually exposed to high temperatures, potential fluid or oil spills, engine maintenance and a high airflow environment. This work looks into the acoustic proofing properties of a non-toxic material ‘SK One Component Polyurethane’ developed by ... -
Study of Ice Adhesion Behavior of SK One Component Polyurethane
(Conference object; Konferansebidrag, 2016-12)Ice adhesion causes many serious problems such as aircraft accidents, navigational issues on ships, and power loss on wind turbines. These challenges are mainly associated with the acute behavior of ice adhesion. The ice adheres when water seeps into the microscopic pores of the material substrate and freezes, thereby, forming an interlocking mechanism. Therefore, surface roughness has a significant ... -
Study of Materials’ Impact Properties for Arctic Marine Structures
(Conference object; Konferansebidrag, 2016-12)It is well understood that sea ice is one of the biggest problems for the safety and reliability of ships and marine structures operating in the Arctic. Specially designed ships, also known as ‘icebreakers’, are usually used to clear ice to make way for merchant and cruise ships. Even then, the ship’s staff must be extremely careful with speed and steering. Heavy impacts of ice result in fatigue and ... -

In addition, it has ... -
User Satisfaction in Augmented Reality-Based Training Using Microsoft HoloLens
(Journal article; Peer reviewed, 2019-01-25)<p>With the recent developments in augmented reality (AR) technologies comes an increased interest in the use of smart glasses for hands-on training. Whether this interest is turned into market success depends at the least on whether the interaction with smart AR glasses satisfies users, an aspect of AR use that so far has received little attention. <p>With this contribution, we seek to change ...
