This is an ongoing work and has two main sections: 1) To investigate the suitable techniques ... -
Using Mutual Charge Scheme to Measure Salinity of Ice
(Journal article; Peer reviewed; Tidsskriftartikkel, 2015)For offshore measurements in Cold Regions, salinity of ice is also a critical parameter (together with many other parameterssuchasicingtype,load,icingrateandmeltingrate)to be identified in order to optimize the performance of anti/de icing systems. Although there are some available sensory solutions in the market to measure real time salinity levels of water, however there are still not many real ... -

A case study to estimate thermal conductivity of ABS in Cold Climate Chamber
(Journal article; Peer reviewed; Tidsskriftartikkel, 2015-10-22)Non steady state thermal conductivity of ABS was estimated using an analytical approach in a Cold Climate Chamber at ?10?C and ?14?C. Two hollow cylinders of ABS of varying thickness were used to estimate the conductivity. The material was porous but the porosity was unknown. This paper is a case study to understand, if it is reasonable to estimate the thermal conductivity using the analytical varying ... -
Study of the required thermal insulation (IREQ) of clothing using infrared imaging
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017)The sense of cold develops due to the increase in heat loss from a human body. Excessive cold can be a health hazard, since excessive heat loss from the body may result in hypothermia/frostbite. Decreased body temperature due to heat loss also affects the physical, manual and perceptive performance of individuals. Therefore, protective measures are taken through clothing that controls and regulates ... -

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, ... -
Regression analysis using a blending type spline construction
(Peer reviewed; Chapter; Bokkapittel, 2017-10-18)Regression analysis allows us to track the dynamics of change in measured data and to investigate their properties. A sufficiently good model allows us to predict the behavior of dependent variables with higher accuracy, and to propose a more precise data generation hypothesis. By using polynomial approximation for big data sets with complex dependencies we get piecewise smooth functions. One way ... -
Remote Operation and Assistance in Human Robot Interactions with Vibrotactile Feedback
(Conference object; Konferansebidrag, 2017-08-08)This paper investigates intuitiveness in human robot interactions with focus on remote operation and assistance. The increasing number of robot applications in small volume production requires new techniques to ease the use of these sophisticated systems. A vibrotactile device was used for experiments. Vibration patterns are developed to represent a cognitive information channel for the remote ... -

State of the Art Review of Atmospheric Icing Sensors
(Journal article; Peer reviewed; Tidsskriftartikkel, 2016-03-31)A state of the art review of atmospheric icing sensors is presented in this article, in order to understand their design and working principle for future developments. It is found that most atmospheric icing sensors which are capable of delivering maximum information are based upon direct measurement of the physical properties (electrical or mechanical) of atmospheric ice. Some field measurements ... -
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 ... -
Numerical Study of Atmospheric Icing on Non Rotating Circular Cylinders in Tandem Arrangement
(Journal article; Tidsskriftartikkel; Peer reviewed, 2013-03-01)Numerical study of atmospheric ice accretion on two non-rotating circular cylinders in tandem arrangement was carried out at different operating and geometric conditions. To validate the numerical model, initially the results of ice accretion on single circular cylinder were compared with the experimental data obtained from CIGELE atmospheric icing research wind tunnel (CAIRWT) [1, 2]. A good agreement ... -
Experimental study of relative permittivity of atmospheric ice
(Journal article; Peer reviewed; Tidsskriftartikkel, 2013-01-01)Atmospheric icing on onshore and offshore structures is problematic, if we don’t detect and remove it. Despite of various ice detection techniques, capacitor based ice sensing technique is interesting one, as it is based on dielectric properties of material. This technique of measuring icing event is simple and cost- effective. Based on the dielectric concept, an experi mental ... -
