Improving the Decision-making of Reverse Logistics Network Design Part I: A MILP Model under Stochastic Environment
(Peer reviewed; Bokkapittel; Book; Bok; 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 ...
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 ...
A Literature Review on Technologies in Future Small-scale Intelligent Manufacturing Systems
(Peer reviewed; Chapter; Bokkapittel, 2018-02-05)
Emergence of global markets forces businesses to become more flexible and adaptive to constantly changing demands and environments. In order to do so, enterprises turn towards application of newest technologies in manufacturing in order to make them intelligent. Since Small and Medium Enterprises play the central role in the domain of European manufacturing, the question arises – based on their ...
Improving the Decision-making of Reverse Logistics Network Design Part II: An Improved Scenario-based Solution Method and Numerical Experimentation
(Peer reviewed; Chapter; Bokkapittel, 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 ...
A Trade-off Model for Green Supply Chain Design: An Efficiency-versus-Emission Analysis
(Peer reviewed; Chapter; Bokkapittel, 2018-04-09)
—With the growing concern of climate change and global warming, the reduction on carbon emissions of supply chain activities have been increasingly focused by both academics and corporates in the last two decades. The increased public awareness on sustainability and stricter environmental policies together enforce the companies to rethink their practices in supply chain design and operations in an ...
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, ...
Predicting Bedside Falls using Current Context
(Peer reviewed; Chapter; Bokkapittel, 2018-02-05)
Each year about a third of the elderly aged 65 or older experience a fall. Many of these falls could be avoided if fall risk assessment and prevention tools where available in the daily living situation. Such tools would need to use the current context as input to predict an imminent fall. This paper presents an approach predicting imminent falls using data from a roof-mounted infrared array combined ...
A multi-objective mathematical programming for sustainable reverse logistics network design. Part II: Model application and analysis
(Peer reviewed; Chapter; Bokkapittel, 2016-02)
Reverse logistics has received more and more attention during the past decade due to the increasing public awareness of sustainable development. Because of the fluctuation in both quantity and quality of the reverse material flow, design and planning of reverse logistics network is much more complicated compared with the forward ones. Therefore, it is important to develop decision support tools for ...
Thyristor based short circuit current injection in isolated grids
(Peer reviewed; Bokkapittel; Chapter, 2017-02-16)
This paper proposes a thyristor based short circuit current injector for providing short circuit current in isolated and weak grids, where sufficient fault current to trigger circuit breakers may not be available. This will allow the use of conventional miniature circuit breakers, which requires high fault current for instantaneous tripping. The method has been validated through experiments.
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 ...
