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 ...
Efficient Distributed Localization Algorithm for Ownership Identification of Reindeer Calf Using Wireless Sensor Networks
(Journal article; Tidsskriftartikkel, 2017)
This paper presents a distributed algorithm for identifying the ownership of new-born reindeer calves using wireless sensor networks (WSNs). Reindeer are semi wild animals giving birth while in the wild. Although reindeer cows usually carry identification tags or signs of their owners, it is difficult to identify the ownership of the calves within a mixed herd. Currently, identification is performed ...
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 ...
A Techno-economic Study of a Biomass Gasification Plant for the Production of Transport Biofuel for Small Communities
(Journal article; Peer reviewed; Tidsskriftartikkel, 2017-03-30)
A techno-economic feasibility study of liquid bio-fuel production from biomass to meet the demand for public transport in small communities is presented. The methodology adopted in this work is based on calculating the demand of fuels required by transport sector and then estimating the amount of available biomass from various sources which can be treated to produce biofuels
to meet the demand ...
Fuel cell technology application for Dubai rail systems
(Peer reviewed; Chapter, 2018-06-11)
Heat engines, such as internal combustion engines, have significant adverse effects on the environment due to their heat and harmful emissions. In addition, they are dependent on energy from fossil resources, which are depleting rapidly and they are not being properly utilized due to the relatively low efficiency of heat engines usually expressed by Carnot's efficiency. The low temperature direct ...
Design of water shock tube for testing shell materials
(Journal article; Tidsskriftartikkel; Peer reviewed, 2014-04-15)
This paper presents design considerations for a shock tube experimental rig used to investigate
the dynamic failure mechanisms of shell geometries subjected to water shock impact loading. In such setup, it is desirable that the drive pressure used within the tube can provide a wide range of impulsive loads on the test structures and some flexibility can be achieved on the applied pulse durations. ...
Measurement of Wind Flow Behavior at the Leeward Side of Porous Fences Using Ultrasonic Anemometer Device
(Journal article; Tidsskriftartikkel; Peer reviewed, 2016-01)
Efficiency of wind fences is evaluated by the reduction of wind velocity and the effective shelter area behind the fence. Fence
porosity is the most influential structural parameters in the porous fence design, and has significant impact on the structure of
wind velocity and turbulence leeward. In this work, three fences with porosity of 23%, 35% and 45% have been tested under
10m/s inlet velocity ...
Ownership Identification of Reindeer Calf Using Wireless Sensor Networks (WSN)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-08-10)
This paper presents a technique for identifying the ownership of new-born reindeer claves using wireless sensor
networks (WSNs), which is an important tool that can be used to acquire useful information about animals’ activities and
movements. Reindeer are semi wild and they give birth while in the wild. Although reindeer cows usually carry identification
tags or signs of their owners, it is ...
Investigation of the Structure of Airflow Behind a Porous Fence Aided by CFD Based Virtual Sensor Data
(Journal article; Tidsskriftartikkel; Peer reviewed, 2015-02-28)
Physical experiments have difficulties to thoroughly investigate the full structure of air flow behind a
porous fence. Physical measurement sensors have their limitations of data acquisitions in turbulent air flow.
Computational Fluid Dynamics (CFD) technique provides an infinite number of virtual sensors that allows
producing quantitative CFD based virtual sensors data for users. In this paper, ...
Review of energy demands and wind resource assessment of the Solovetsky Archipelago
(Journal article; Tidsskriftartikkel, 2019-07)
This paper aims to analyse the current situation of the energy system of the remote island territory of Solovetsky
Archipelago. The Solovetsky historical and cultural complex was included in the list of UNESCO World Heritage
Sites. Diesel fuel, which is used on the archipelago is expensive and pollutes the environment. By using
Computational Fluid Dynamics (CFD) based numerical method, this study ...
