NaKA sorbents with high CO2-over-N2 selectivity and high capacity to adsorb CO2
- 2010

Journal article (peer-reviewed)abstract
- The uptake of carbon dioxide and nitrogen gas by zeolite NaKA was studied. A very high ideal CO2-over-N2 selectivity and a high CO2 capacity were observed at an optimal K+ content of 17 at.%. NaKA is a very promising adsorbent for CO2 separation from water-free flue gases.

External communication of automated shuttles: Results, experiences, and lessons learned from three European long-term research projects
- 2022
-
In: Frontiers Robotics AI. - : Frontiers Media SA. - 2296-9144. ; 9
-
Journal article (peer-reviewed)abstract
- Automated shuttles are already seeing deployment in many places across the world and have the potential to transform public mobility to be safer and more accessible. During the current transition phase from fully manual vehicles toward higher degrees of automation and resulting mixed traffic, there is a heightened need for additional communication or external indicators to comprehend automated vehicle actions for other road users. In this work, we present and discuss the results from seven studies (three preparatory and four main studies) conducted in three European countries aimed at investigating and providing a variety of such external communication solutions to facilitate the exchange of information between automated shuttles and other motorized and non-motorized road users.

Face-To-Face With A Robot : What do we actually talk about?
- 2013
-
In: International Journal of Humanoid Robotics. - 0219-8436. ; 10:1, s. 1350011-
-
Journal article (peer-reviewed)abstract
- While much of the state-of-the-art research in human-robot interaction (HRI) investigates task-oriented interaction, this paper aims at exploring what people talk about to a robot if the content of the conversation is not predefined. We used the robot head Furhat to explore the conversational behavior of people who encounter a robot in the public setting of a robot exhibition in a scientific museum, but without a predefined purpose. Upon analyzing the conversations, it could be shown that a sophisticated robot provides an inviting atmosphere for people to engage in interaction and to be experimental and challenge the robot's capabilities. Many visitors to the exhibition were willing to go beyond the guiding questions that were provided as a starting point. Amongst other things, they asked Furhat questions concerning the robot itself, such as how it would define a robot, or if it plans to take over the world. People were also interested in the feelings and likes of the robot and they asked many personal questions - this is how Furhat ended up with its first marriage proposal. People who talked to Furhat were asked to complete a questionnaire on their assessment of the conversation, with which we could show that the interaction with Furhat was rated as a pleasant experience.

Method for investigation of frictional properties at impact loading
- 1999
-
In: Journal of Sound and Vibration. - : Elsevier BV. - 0022-460X .- 1095-8568. ; 222:4, s. 669-677

Journal article (peer-reviewed)abstract
- In the assessment of lubricant performance and also in various other contact applications it is of importance to know the frictional qualities of a surface. Under quasi-static conditions, normal and frictional forces are measured using force transducers but the task is more difficult when loads are transient. The experimental method presented in this paper is based on the analysis of propagating waves in a beam, due to an impact on the end surface. The impact is oblique and therefore a transverse as well as a normal force is generated. The normal force history is measured from the axial non-dispersive wave using strain gauges. Transverse force and bending moment both generate dispersive flexural waves. From the FFT of two transverse acceleration histories, the frictional force at the end of the rod is evaluated using beam theory. The relation between normal and frictional force histories displays the frictional properties at the impact. Preliminary results are presented
