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 ...
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 ...
Ice Detection Experimentation Setup Using Infrared and Active Heating
(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 ...
Refinements of some limit hardy-Type Inequalities via Superquadracity
(Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-03)
Refinements of some limit Hardy-type inequalities are derived and discussed using the concept of superquadracity. We also proved that all three constants appearing in the refined inequalities obtained are sharp. The natural turning point of our refined Hardy inequality is p=2 and for this case we have even equality.
Sound waves in fluidized bed using CFD–DEM simulations
(Journal article; Peer reviewed; Tidsskriftartikkel, 2017-10-16)
The speed of sound waves is investigated using CFD-DEM numerical simulations. Appropriate initial and boundary conditions are applied to capture the phenomenon. The effect of varying the height of the bed is also studied. The results of the simulations matched those from literature. The pressure and particle velocity profiles from the simulation showed the oscillatory behavior. Functions (based on ...
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 ...
Subsumption architecture applied to flight control using composite rotations
(Peer reviewed; Tidsskriftartikkel; Journal article, 2016-03-19)
In this paper the subsumption theory is applied to flight control through composite rotations where multiple tasks can be defined as simple rotations. The tasks can then be arranged as a hierarchy, where the primary task is always fully pursued, and conflicting lower level tasks are removed by the primary rotation. The concept is applied to a group of uavs that move through an urban terrain while ...
Some inequalities for Cesàro means of double Vilenkin-Fourier series
(Journal article; Peer reviewed; Tidsskriftartikkel, 2018-12-19)
In this paper, we state and prove some new inequalities related to the rate of Lp approximation by Cesàro means of the quadratic partial sums of double Vilenkin–Fourier series of functions from Lp.
