Shock Tube. Detail overview of equipment and instruments in the shock tube experimental setup
(Book; Bok, 2015)
The shock tube is a device in which a normal shock wave is produced by the interaction of fluids at significantly high-pressure difference. The shock tube is comprised of two sections known as driver and driven sections. These two sections are interacted with the high-speed valve or a bursting disc. When the interaction happens, a shock wave forms almost instantaneously and propagates into the driven ...
Approaches to learning of linear algebra among engineering students
(Peer reviewed; Bok; Book; Bokkapittel; Chapter, 2017-02)
The present paper investigates engineering students` own descriptions of what they mean by learning of linear algebra and how they know that they have learned something. I seek to extract keywords from engineering students` descriptions of learning of this discipline by drawing on grounded theory techniques and classifying the answers in conceptual and procedural approaches. By this, both detailed ...
Exploring Tensions in a Mathematical Course for Engineers utilizing a Flipped Classroom Approach
(Book; Chapter; Bok; Bokkapittel; Peer reviewed, 2017-02)
Flipped Classroom approaches to teaching are becoming increasingly popular in higher education, but there is a lack of empirical research. We present here a study performed during an engineering course for 20 students at a Norwegian university, on student appropriation towards Flipped Classroom through interviews, questionnaire, video/quiz usage statistics and classroom filming. We approach this ...
Multi-source data collection for state-of-the-art data analysis from ground-proximate images in sea ice classification
(Peer reviewed; Konferansebidrag; Bok; Conference object; Book, 2017-08-08)
In modern data analysis it is imperative to use well maintained data sources with curated content. This publication gives an approach for research areas, where there is no such central facility. The specific area used here is sea ice classification from images. The publication is split into two parts. The first part describes the integration of discontinuous sources for different aspects of data ...
Solution of Pure Scattering Radiation Transport Equation (RTE) Using Finite Difference Method (FDM)
(Peer reviewed; Book; Bok; Bokkapittel; Chapter, 2017-05-19)
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, ...
Digitalization of the power business: How to make this work?
(Peer reviewed; Book; Bok; Bokkapittel; Chapter, 2018)
As a result of the digitalization of the power business in Norway and Europa, a lot of new possibilities and challenges arise. In 2014 an expert committee one outlined a proposal for the future grid company structure in Norway (Reiten, 2014). In addition, new technologies are being implemented in the system. Wind power, solar power, un-regulated small hydro power production, battery storage domestic ...
Improving the Decision-making of Reverse Logistics Network Design Part I: A MILP Model under Stochastic Environment
(Peer reviewed; Bok; Bokkapittel; Book; Chapter, 2018-02-11)
The study of the network design problems related to reverse supply chain and reverse logistics is of great interest for both academicians and practitioners due to its important role for a sustainable society. However, reverse logistics network design is a complex decision-making problem that involves several interactive factors and faces many uncertainties. Thus, in order to improve the reverse ...
Dual-quaternion backstepping control for a fully-actuated rigid-body
(Peer reviewed; Book; Chapter, 2018-08-16)
In this paper dual-quaternions are used to model a fully actuated rigid-body. A backstepping-controller that solves the trajectory tracking problem is derived and proved to provide uniform asymptotical stabilization of the error dynamics. Numerical simulations are provided where the controller is compared to existing dual-quaternion tracking controllers and it is shown to have similar performance.
Curvature Continuous Path Generation for UAVs based on Generalized Expo-Rational B-Splines
(Peer reviewed; Book; Chapter, 2018)
This paper proposes a new path-planning algorithm based on GERBS to generate curvature continuous paths. The algorithm blends between a set of local curves generating a global smooth path which also interpolates the midpoint of the curves. Numerical examples are provided which demonstrates the potential of the proposed algorithm.
Human-Robot Collaboration: Task Sharing Through Virtual Reality
(Peer reviewed; Book; Chapter, 2018-12-31)
Collaborative Robots provide many possibilities, when it comes to Human-Robot Collaboration. Until now, these approaches are usually custom made, sensor-integrated solutions, where the robot's safety controller ensures the safety of the human worker. These solutions are according to today's rules and standards. We propose to extend these solutions with including Virtual Realty as a sensor and to ...
