Solution of Pure Scattering Radiation Transport Equation (RTE) Using Finite Difference Method (FDM)
(Conference object; Konferansebidrag, 2017-06)Radiative transfer is the physical phenomenon of energy transfer in the form of electromagnetic radiation. The propagation of radiation through a medium is affected by absorption, emission, and scattering. Radiative Transfer Equation (RTE) have been applied in a many subjects including optics, astrophysics, atmospheric science, remote sensing, etc. Analytic solutions for RTE exist for simple cases, ... -
Detection of Red Dye in Diesel Oil
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)Developing a sensitive and effective instrument for detecting the presence of red dye in diesel fuel is very advantageous for governments in preventing tax loss by controlling illegal use of the diesel fuel. The objective of this work has been to investigate and develop an instrument to detect red dye in diesel, based on the principle of absorption. The peaks of absorption in red and pure diesel ... -
A field study of atmospheric icing analysis in a complex terrain of the high north
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-12)Analyses of atmospheric icing events hold the key for computing the significant parameters leading to icing load calculations. In the cold regions of the high north, atmospheric icing loads on structures become important when it comes to design and safety of infrastructures. Furthermore, icing load calculations over a certain period of time provide a vital input for designers to improve the ... -
Review of marine icing and anti-/de-icing systems
(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 ... -
Detection of red dye in diesel oil using UV-absorption and silicon photo detector
(Conference object; Konferansebidrag, 2016-12-08)Developing a sensitive and effective instrument for detecting the presence of red dye in diesel fuel is very advantageous for governments in preventing tax loss by controlling illegal use of the diesel fuel. The objective of this work has been to investigate and develop an instrument to detect red dye in diesel, based on the principle of absorption. The peaks of absorption in red and pure diesel ... -
Influence of local and regional air pollution on atmospheric measurements in Ny-Ålesund
(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 ... -
Integrated Oxyfuel Power Plant with Improved CO2 Separation and Compression Technology for EOR application
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-06-25)An integrated advanced supercritical coal-fired oxyfuel power plant with a novel cryogenic CO2 separation and compression technology for high purity CO2 to suit injection for enhanced oil recovery purposes is investigated. The full process is modelled in Aspen Plus® consisting of: an Air Separation Unit (ASU), an Advanced Supercritical Pulverised Fuel (ASC PF) power plant with a bituminous coal ... -
Modelled and observed sea-spray icing in Arctic-Norwegian waters
(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 ... -
Modeling Bottom-Up Visual Attention Using Dihedral Group D4
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08-15)In this paper, first, we briefly describe the dihedral group D4 that serves as the basis for calculating saliency in our proposed model. Second, our saliency model makes two major changes in a latest state-of-the-art model known as group-based asymmetry. First, based on the properties of the dihedral group D4, we simplify the asymmetry calculations associated with the measurement of saliency. ...
