• Detection, Identification and Size distribution of micro-plastic particles 

      Varughese, Bindu Sara; Edvardsen, Kåre (Conference object; Konferansebidrag, 2017)
      Pollution by micro-plastic in ecosystems is one of the major problems we are facing now, especially in marine environment. Many studies are going on the detection of different micro substances that pollute our environment. Micro-plastics are among the more frequent pollutants of the sort in aquatic ecosystems. There have been some studies earlier on methodologies to detect and identify micro-plastic ...
    • Fluorescent marking of roads in high-north 

      Khawaja, Hassan; Varughese, Bindu Sara; Edvardsen, Kåre (Conference object; Konferansebidrag, 2017)
      The project objective is to investigate into luminescent coating materials that can be used in marking the roads in high-north. The idea of the project is not entirely new, and efforts have been worldwide to find an energy efficient solution to the street lights. Earlier work conducted in the Netherlands showed quite promising results. However, the challenges include weatherproofing the coat such ...
    • Ice Detection Experimentation Setup Using Infrared and Active Heating 

      Rashid, Taimur; Khawaja, Hassan Abbas; Edvardsen, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-07-24)
      The paper shows the possible implementation of Infrared (IR) ice detection technique. The experimental setup is implemented keeping in view of the marine icing phenomena over the ships and offshore structures. The detection mechanism is unique from the passive IR detection by introducing the active heating concept. The intervention of the active heating information inside the IR ice detection system ...
    • Influence of local and regional air pollution on atmospheric measurements in Ny-Ålesund 

      Dekhtyareva, Alena; Edvardsen, Kåre; Holmén, Kim; Hermansen, Ove; Hansson, Hans-Christen (Journal article; Tidsskriftartikkel; Peer reviewed, 2016)
      The Zeppelin observatory is a research station near the village Ny-Ålesund in Svalbard. The facility delivers data to international projects devoted to high data quality monitoring of the background air pollution in the Arctic. An approach for quantifying the influence of local and regional pollution on measurements that may be misinterpreted as long-range transported one, is presented here. The ...
    • Investigation of Composite Mechanical Properties from Additive Manufacturing 

      Andleeb, Zahra; Khawaja, Hassan; Andersen, Kristian G; Edvardsen, Kåre; Moatamedi, Mojtaba (Conference object; Konferansebidrag, 2022)
      Manufacturers consider carbon fiber as a wonder material for the world's economy. Its distinctive combination of high strength and low weight has helped drive the wind power revolution and make aircraft and ships more fuel-efficient. In addition, the carbon fiber structures can function longer and are more rigid than the traditional metallic models, making them more resilient in cold and more efficient ...
    • Measuring Thickness of Marine Ice Using IR Thermography 

      Rashid, Taimur; Khawaja, Hassan; Edvardsen, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-09-04)
      <p>There are several challenges to operating in a cold climate. Marine icing is one of them, and its mitigation is vital for marine operations.</p> <p>The presented work is a laboratory-scale setup to measure marine ice thickness. The developed methodology can be applied towards de-/anti-icing setups. The method described is based on measuring the average surface temperatures of the marine ice. ...
    • Modelled and observed sea-spray icing in Arctic-Norwegian waters 

      Samuelsen, Eirik Mikal; Edvardsen, Kåre; Graversen, Rune (Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-11-15)
      Hazardous marine icing is a major concern for ships operating in Arctic waters during freezing conditions. Sea spray generated by the interaction between a ship and ocean waves is the most important water source in these dangerous icing events. Although there exist several data sets with observations of ice accretion in conjunction with meteorological and oceanographic parameters, these data sets ...
    • Review of marine icing and anti-/de-icing systems 

      Rashid, Taimur; Khawaja, Hassan Abbas; Edvardsen, Kåre (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-17)
      The aim of this work is to review the phenomenon of icing in marine operations. The focus is on two main sources of icing, namely atmospheric and sea spray. The literature reveals that sea spray icing is the main contributor to marine icing. This work discusses the available ice accretion prediction models on ships and offshore structures. It also reviews the anti-/de-icing technologies that can be ...
