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 ... -
Ice Accretion on Fixed-Wing Unmanned Aerial Vehicle—A Review Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-28)Ice accretion on commercial aircraft operating at high Reynolds numbers has been extensively studied in the literature, but a direct transformation of these results to an Unmanned Aerial Vehicle (UAV) operating at low Reynolds numbers is not straightforward. Changes in Reynolds number have a significant impact on the ice accretion physics. Previously, only a few researchers worked in this area, ... -
Ice Accretion on Rotary-Wing Unmanned Aerial Vehicles—A Review Study
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-08)Ice accretion on rotary-wing unmanned aerial vehicles (RWUAVs) needs to be studied separately from the fixed-wing UAVs because of the additional flow complexities induced by the propeller rotation. The aerodynamics of rotatory wings are extremely challenging compared to the fixed-wing configuration. Atmospheric icing can be considered a hazard that can plague the operation of UAVs, especially in the ... -

An Improved Mathematical Model for Green Lock Scheduling Problem of the Three Gorges Dam
(Journal article; Peer reviewed, 2019-05-08)In recent years, the environmental pollutions at the Three Gorges Dam have become an increasingly concerning issue of the Chinese government. One of the most significant environmental problems is the carbon emissions from the lockage operations at the two ship locks of the Three Gorges Dam. Currently, due to the large amount of vessels passing through the dam, there is always a long queue of vessels ... -

Incorporating flexible capacity in the planning of a multi-product multi-echelon sustainable reverse logistics network under uncertainty
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-07-05)With the focus on sustainable development, the value recovery from End-of-Life (EOL) and End-of-Use (EOU) products has been given considerable attention by the whole society. Reverse logistics is the process for value recovery and re-creation through a series of activities, i.e., repair, remanufacturing, recycling and energy recovery. However, due to the stochastic reverse product flow, unstable ... -
Influence of large-scale asperities on the stability of concrete dams
(Chapter; Bokkapittel, 2022)For concrete dams founded on rock, there are only a few options in the common analysis methods to account for large‐scale asperities. However, previous research alludes that they have a significant impact on the behaviour of interfaces under shear. This study investigates the behaviour of concrete dam scale models with varying interface geometries, under a realistic set of eccentric loads. The outcome ... -
An Integrated Approach for Assessing Suppliers Considering Economic Sustainability Innovation

Intelligent cost-effective winter road maintenance by predicting road surface temperature using machine learning techniques
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-04-06)Since Winter Road Maintenance (WRM) is an important activity in Nordic countries, accurate intelligent cost-effective WRM can create precise advance plans for developing decision support systems to improve traffic safety on the roads, while reducing cost and negative environmental impacts. Lack of comprehensive knowledge and inaccurate WRM information would lead to a certain loss of WRM budget, ... -
Introduction of cyber-physical system in robotized press-brake line for metal industry
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-11)Bin picking is a typical work, which is easy to automate up to a given complexity of the work-piece dimensions. In case of casted work-pieces, the dimensions are most of the time not accurate enough for an industrial robot to be able to pick it up without additional sensors/intelligence. In this paper we introduce a cyber-physical system, where all sensors, actuators, machines and industrial robot ... -
