On the Control of a Seawater-Hydraulic Wind Farm with the Delft Offshore Turbine
No full textOffshore wind energy is a promising prospect to meet the ever-growing demand for energy. Its reputation is, however, sullied by high costs not yet competitive with conventional energy resources. The Delft Offshore Turbine (DOT) attempts to radically reduce the Levelized Cost of Energy (LCOE) of offshore wind by utilising a seawater-hydrostatic transmission from individual wind turbines to a central power station, where power is generated collectively. Recent theoretical research on the DOT employed variable displacement pumps in the wind turbines interconnected through a collective pipeline. A variable displacement pump does not yet commercially exist and leaves the implementation of a fixed-displacement pump more viable in the near future. Recent practical research implemented a fixed-displacement pump with an individual pipeline. To benefit from the economy of scale however, a collective pipeline is preferred. The DOT wind farm considered in this thesis incorporates fixed-displacement pumps interconnected through a collective pipeline. The difficulty herein arises from the combination of an equal hydraulic torque but varying aerodynamic torque throughout the wind farm. The combined effect results in the inability to control individual rotor speeds, which inevitably leads to suboptimal individual rotor efficiency. This research explores a novel control strategy that obtains the best suboptimal performance when the wind turbines are controlled through a collective pressure.Mechanical Engineering | Systems and Contro
Evaluation of a Pilot Game to Change Civil Servants’ Willingness Towards Open Data Policy Making
No full textThe adoption of open data policy-making by governments is limited due to different types of constraints. Civil servants are reluctant to open their data to the public for many reasons. The lack of knowledge of benefits that can be produced by the release of data and the overestimation of risks and operational complexity seems to decrease their willingness to support the opening of data. The idea that a serious game intervention can change awareness of participants in different domains is already known. Yet, games are domain dependent and concepts differ per domain. A game has never been used for the emerging domain of open data in which civil servants are operating in a bureaucratic environment having a risk-averse culture and strict institutional rules. A role-playing game prototype was designed for civil servants to experience open data policy-making. This paper analyses its first results aiming at changes of perception for the participants of the game and aims to understand the changes in behavior of civil servants that played it. For some participants, the game influenced their attitude, whereas others were not influenced. Suggesting that different approaches might be necessary for changing the attitude of different groups.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Information and Communication Technolog
The Tacit Knowledge in Games: From Validation to Debriefing
No full textGame sessions consist of three phases: briefing, gameplay, and debriefing, with the latter being considered the most important feature of games. Nevertheless, given that games are considered by many to be more of an artistic form rather than a scientific artifact, a question that rises is: Can game sessions in general and debriefing in particular be analyzed and performed in a rigorous scientific way? In other words, can they be consistently structured, given the different characteristics of games, and can clear criteria on what would constitute a successful game session and debriefing be defined? The answer to these questions is yes. Yet, it remains a challenge to extract the knowledge of experts, which resides to a large extent in the tacit knowledge spectrum. Hence, the aim of this paper is to shed some light in this tacit knowledge possessed by experts and to gain understanding on why certain practices are more prone to success than others as well as bring into the surface other practices that have remained well hidden. In order to accomplish this goal, three rounds of interviews were conducted.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Policy Analysi

Supplementary data for the paper: Replicating five pupillometry studies of Eckhard Hess
No full textSeveral
papers by Eckhard Hess from the 1960s and 1970s report that the pupils dilate
or constrict according to the interest value, arousing content, or mental
demands of visual stimuli. However, Hess mostly used small sample sizes and undocumented
luminance control. In a first experiment (N = 182) and a second preregistered
experiment (N = 147), we replicated five studies of Hess using modern
equipment. Our experiments (1) did not support the hypothesis of gender
differences in pupil diameter change with respect to baseline (PC) when viewing
stimuli of different interest value, (2) showed that solving more difficult
multiplications yields a larger PC in the seconds before providing an answer
and a larger maximum PC, but a smaller PC at a fixed time after the onset of
the multiplication, (3) did not support the hypothesis that participants’ PC
mimics the pupil diameter in a pair of schematic eyes but not in single-eyed or
three-eyed stimuli, (4) did not support the hypothesis of gender differences in
PC when watching a video of a male trying to escape a mob, and (5) supported
the hypothesis that arousing words yield a higher PC than non-arousing words.
Although we did not observe consistent gender differences in PC, supplementary
analyses showed gender differences in eye movements towards erogenous zones.
Furthermore, PC strongly correlated with the luminance of the locations where
participants looked. Overall, our replications confirm Hess’s findings that
pupils dilate in response to mental demands and stimuli of an arousing nature. Hess’s
hypotheses regarding pupil mimicry and gender differences in pupil dilation did
not replicate.</p

Frame Game as Teaching Methodology in Higher Education: The Case of RElastiCity
No full textThe objective of the study is to illustrate the use of the frame game, RElastiCity as a framework to learn about the resilience of urban areas and the shocks and stresses in those areas. The question is if use of the frame game as a basis for game co-design is a useful approach to explore complex systems and its dynamics. This study covers the exploratory application of the approach in two university courses in the Netherlands. The results show divergent student experiences between the two courses. The main difference between the courses was the scope of the co-design assignment and the amount of time students had to complete the design process. It was found that using frame games as a framework for understanding complex systems is useful if students have sufficient time to investigate the topic, develop the game and playtest the game.Green Open Access added to TU Delft Institutional Repository 'You share, we take care!' - Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Organisation & GovernanceDesign Conceptualization and Communicatio
“Risk Management Can Actually Be Fun”: Using the Serious Cards for Biosafety Game to Stimulate Proper Discussions About Biosafety
No full textAs part of a Dutch Science Foundation project called T-TRIPP, the authors developed the serious game Cards for Biosafety. The aim of Cards for Biosafety is to let young biotechnology researchers learn more about biosafety. Analyses of workshops with researchers from the biotechnology domain as well as results of interviews with several biosafety officers clearly indicated the need for such a serious game with a focus on educational learning. Cards for Biosafety is a physical (also playable online on Tabletopia) round-based card game and playable with up to eight players. The game itself consists of scenario, risk and measure cards, and the task of the players is to choose risk and measure cards that fit the scenario explained by the facilitator at the beginning of each round. To test the efficiency of Cards for Biosafety as a learning tool, the authors conducted two online-workshops with twelve participants. The results of these sessions have not only shown that Cards for Biosafety is a well-designed game, but also a successful game to achieve the intended learning goal. In addition, the authors recognized that ‘fun’ is an important element in the game which leads to ‘learning’ in a very effective way. Future research should focus on the role of such positive states in serious games and their influence on learning outcomes.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Policy AnalysisGame La
Rolling out the red (and green) carpet: Supporting driver decision making in automation-to-manual transitions
No full textThis paper assessed four types of human–machine interfaces (HMIs), classified according to the stages of automation proposed by Parasuraman et al. [“A model for types and levels of human interaction with automation,” IEEE Trans. Syst. Man, Cybern. A, Syst. Humans, vol. 30, no. 3, pp. 286–297, May 2000]. We hypothesized that drivers would implement decisions (lane changing or braking) faster and more correctly when receiving support at a higher automation stage during transitions from conditionally automated driving to manual driving. In total, 25 participants with a mean age of 25.7 years (range 19–36 years) drove four trials in a driving simulator, experiencing four HMIs having the following different stages of automation: baseline (information acquisition—low), sphere (information acquisition—high), carpet (information analysis), and arrow (decision selection), presented as visual overlays on the surroundings. The HMIs provided information during two scenarios, namely a lane change and a braking scenario. Results showed that the HMIs did not significantly affect the drivers’ initial reaction to the take-over request. Improvements were found, however, in the decision-making process: When drivers experienced the carpet or arrow interface, an improvement in correct decisions (i.e., to brake or change lane) occurred. It is concluded that visual HMIs can assist drivers in making a correct braking or lane change maneuver in a take-over scenario. Future research could be directed toward misuse, disuse, errors of omission, and errors of commission.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Human-Robot Interactio
