Towards a simulation-based tuning of motion cueing algorithms
2016
Abstract This paper deals with the problem of finding the best values for the parameters of Motion Cueing Algorithms (MCA). MCA are responsible for controlling the movements of robotic motion platforms used to generate the gravito-inertial cues of vehicle simulators. The values of their multiple parameters, or coefficients, are hard to establish and they dramatically change the behaviour of MCA. The problem has been traditionally addressed in a subjective, partially non-systematic, iterative, time-consuming way, by seeking pilot/driver feedback on the generated motion cues. The aim of this paper is to introduce a different approach to solve the problem of MCA tuning, by making use of a simu…
Importance of Sampling Frequency to Detect Differential Timing of Migration: A Case Study with BlackcapsSylvia atricapilla
2009
Our aim was to assess to what extent detection of differential timing of passage in migrant birds depends on the sampling frequency (SF). We determined if Blackcaps Sylvia atricapilla performed differential migration by age and sex when passing over N Iberia. We mist netted and ringed migrating Blackcaps at a stopover site, both during the autumn (2005) and the spring (2006) migrations. During autumn, adult female Blackcaps passed later than juvenile birds and adult males. In spring, however, migration differed mainly by sex rather than by age. In particular, males passed over earlier than females, likely due to the pressure on males to earlier arrival at their breeding areas. A simulation …
Technological, Organisational and Socio-Interactional Affordances in Simulation-Based Collaborative Learning
2021
Analysis of the applicability of a learning technology requires an evaluation of how the affordances of the learning environment respond to users’ needs. We examine affordances in a simulation-based collaborative learning environment from the learners’ viewpoint. Our analysis focuses on three types of affordances: technological, organisational and socio-interactional. The findings show how teams of learners employ the different types of affordances in their collaborative tasks. In addition, our analysis illustrates the interdependent and interlinked nature of the affordances. We offer an analytical understanding of the dynamics among different kinds of affordances and show how they can be a…
Students of Religion Studying Social Conflict Through Simulation and Modelling: An Exploration
2020
Researchers at our university use modelling and simulation (M&S) to study religious conflicts, and we wanted to introduce undergraduate students of religion to this research approach. Hence, we started a three-year educational design research project to empirically study ways to introduce these students to M&S as a viable research method in their discipline. The research project will entail several iterations, which aim to have a feasible and effective design of lessons and a better understanding of the learning processes. The first iteration was exploratory and is reported here. For this exploration, we organised a seminar, which was videotaped for post hoc analysis. The seminar started wi…
A DC-DC power converter for PV module characterization
2014
In this paper, a standard-compliant electronic load setup for PV module curve detection which features high accuracy, low cost and components count is proposed. The proposed device is based on a DC-DC power converter in open-loop configuration. The proposed system is designed according to regulation constraints in order to achieve high performances in curve detection. Design criteria are discussed. The model is implemented in PSIM environment. Simulation based on data input of a commercial PV Conergy E215P module are carried out under several environmental conditions to show the accuracy of the proposed electronic load. Simulation results are reported.
Strictness vs. flexibility: Simulation-based recognition of strategies and its success in soccer
2021
Abstract Introduction: Recognition and optimization of strategies in sport games is difficult in particular in case of team games, where a number of players are acting “independently” of each other. One way to improve the situation is to cluster the teams into a small number of tactical groups and to analyze the interaction of those groups. The aim of the study is the evaluation of the applicability of SOCCER© simulation in professional soccer by analyzing and simulation of the tactical group interaction. Methods: The players’ positions of tactical groups in soccer can be mapped to formation-patterns and then reflect strategic behaviour and interaction. Based on this information, Monte Carl…
The Rise and Fall of Humanitarian Citizen Initiatives: A Simulation-Based Approach
2020
Citizen Initiatives for Global Solidarity (CIGS) are small, ad hoc, volunteer organizations that arise in certain humanitarian and development contexts. They operate outside of traditional aid structures and may or may not cooperate with traditional government and nongovernmental organizations. Using agent-based modeling, we derive narrative-based, qualitative scenarios from simulation data to extend the theoretical discussions of CIGS as a phenomenon. The scenarios allow further discussion of the role that CIGS may play as development and humanitarian response actors outside of the traditional context-specific descriptions of CIGS that permeate the development literature. We find that scen…
New developments in simulation-based harbour crane training
2011
This paper presents the efforts that have been made during the development of a set of harbour training simulators to improve their quality. The paper focuses on two main research lines: the improvement of complex physical systems involved in the simulation and the analysis of hardware architecture solutions. Cable-based hoist systems and bulk materials are systems present in different harbour equipment and are usually simulated with poor quality due to their complexity. In this paper physics-based models for the interactive simulation of these systems are proposed and applied to real cases. Also, different hardware simulator architectures are analysed and different approaches are proposed …
