Torque and Axial Loading Physics for Measuring Atmospheric Icing Load and Icing Rate
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2015-01-31)Measuring icing load and icing rate are important parameters for an atmospheric icing sensor. A new icing sensor has recently been designed and developed at Narvik University College for measuring atmospheric icing rate, icing load and icing type. Unlike the existing atmospheric icing sensors commercially available in market, which uses the axial loading for measuring icing load and icing rate, this ... -

The real and imaginary components of discrete Fourier transform were recorded at each frequency increment in order calculate the gain factor at each ... -
Welding Certification for Autonomous Robotized Welding
(Chapter; Bokkapittel, 2016-10-23)The increased production of more and more complex products challenges the accuracy of manual welding, and increase the time it takes to program automatic welding systems. The main objective for the article is to explore if current regulations and standards are able to accommodate the shift from automatic welding to autonomous welding systems. To do this, the most current and applicable standards ... -
SMEs challenges and needs in relation to innovation agendas and strategies
(Conference object; Konferansebidrag, 2016-06-21)Regional research project are, as is also regional industry, highly need-based. That is, understanding the stakeholders’ (or customers’) real challenges and related needs is important. This study is based on interviews with SMEs in the Northern parts of Finland, Norway and Sweden, but also on available innovation agendas and strategies for each country. The differences among the companies in those ... -
Multiphysics based Numerical Study of Atmospheric Ice Accretion on a Full Scale Horizontal Axis Wind Turbine Blade
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-08)Atmospheric icing on wind turbines have been recognized as a hindrance to the development of the wind power in cold regions, where uncertainty surrounding the effects of icing on energy production may prevent otherwise good wind resources from being utilized. This research paper is focused on to numerically simulate the rate and shape of atmospheric ice accretion on a full-scale horizontal axis ... -
Experimental validation of icing rate using rotational load
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-04-16)Icing load and icing rate are necessary feedback variables for an intelligent anti/de-icing systemtowork effectively in harsh cold environment of high north. These parametersmay be measured by axial loadings or by rotational loadings, as a function of current demand. However the former may not necessarily be dynamic, whereas the later necessarily be rotational. Sufficiently at a fixed rpm, a ... -
Multiphysics Based Design Study of an Atmospheric Icing Sensor
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016)A design study of an atmospheric icing sensor is presented in this article. The proposed design of the sensor is aimed to detect an atmospheric icing event, to determine ice type as well as to measure icing load, icing rate and melting rate. This sensor is constantly slowly rotating cylinder with four fins which measure atmospheric icing load and icing rate using rotational load measurement technique. ... -
A Goal Programming Approach for Green Supply Chain Network Optimization
(Chapter; Bokkapittel, 2016-10)Green supply chain management has been focused by both academicians and practitioners in recent years due to the increased public awareness on environmental problems and sustainable development. In this paper, a decision aided model for green supply chain network design and optimization is proposed to justify both economic and environmental performance in an optimal fashion. The model is formulated ... -
A general reverse logistics network design model for product reuse and recycling with environmental considerations
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2016-04-02)Reverse logistics is believed to be one of the most promising solutions for capturing the remaining values from used products and has been extensively focused by both academics and practitioners during the past two decades. Conceptual framework, mathematical programming and computational algorithms have been developed for decision making at strategic, tactical and operational levels of a reverse ... -
Optimization of long-term performance of municipal solid waste management system: A bi-objective mathematical model
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2015)Management of municipal solid waste has becoming an extremely important topic for any urban authorities in recent years due to the rapidly increasing solid waste quantity and potential environmental pollution. In this paper, a bi-objective dynamic linear programming model is developed for decision making and supporting in the long-term operation of municipal solid waste management system. The proposed ... -
A green supply chain network design model for enhancing competitiveness and sustainability of companies in high north arctic regions
(Peer reviewed; Journal article; Tidsskriftsartikkel, 2014)To survive in today's competitive and ever-changing marketplace, companies need not only to engage in their products and/or services, but also to focus on the management of the whole supply chain. Effectively managing and balancing the profitability and interconnection of each player in the supply chain will improve the overall supply chain surplus as well as individual profit. However, it is extremely ... -
An improved multi-objective programming with augmented ε-constraint method for hazardous waste location-routing problem
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-05-31)Hazardous waste location-routing problems are of importance due to the potential risk for nearby residents and the environment. In this paper, an improved mathematical formulation is developed based upon a multi-objective mixed integer programming approach. The model aims at assisting decision makers in selecting locations for different facilities including treatment plants, recycling plants and ... -
A stochastic programming approach with improved multi-criteria scenario-based solution method for sustainable reverse logistics design of Waste electrical and electronic equipment (WEEE)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-12-17)Today, the increased public concern for sustainable development and more stringent environmental regulations have become the most important driving forces for value recovery from end-of-life and end-of use products through reverse logistics.
