Blommestein, Daniel (author)Nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with ultraviolet-curable resins. Significant potential of large-area nanopatterning lies in its capacity to greatly enhance the performance of an abundance of devices and foster the creation of cutting-edge products. However, current large-area...master thesis 2023

de Waal, Jeremy (author), Rauf, Namo (author)Before the project was started, there was an energy system integrator demonstrator. This demonstrator was purely software, there was no physical interaction possible with it. It demonstrated the energy system by simulations. The objective of this project was to design and built peripherals that represents the components of an energy system....bachelor thesis 2023

Perdikis, Charalampos (author)Inverse Reinforcement Learning (IRL) aims to recover a reward function from expert demonstrations in a Markov Decision Process (MDP). The objective is to understand the underlying intentions and behaviors of experts and derive a reward function based on their reasoning, rather than their exact actions. However, expert demonstrations can be...bachelor thesis 2023

Callejon Cantero, M. (author), Pastor-Rodriguez, A. (author), Siemes, C. (author)The uncertainty on Thermospheric Mass Density (TMD), as derived from atmospheric models, can reach extremely high values. This effect is noteworthy in Low Earth Orbit (LEO), where atmospheric drag is the main perturbing force, as well as the most uncertain. LEO harbours almost 18,000 space objects at the end of 2021, around 60% of the total...conference paper 2023

Langbroek, M. (author), Bassa, Cees (author), Molczan, Ted (author)Meaningful SSA work on earth-orbiting satellites can be done on a shoe-string budget, with modest, off the shelf equipment. This has been shown by an informal group of self-funded Independent Space Observers (“ISO’s”) organized around the Seesat-L mailing list. Literally from their backyards, they track some 200 “classified” objects – objects...conference paper 2023

Speretta, S. (author), Uludag, M.S. (author), Menicucci, A. (author), Ferrario, Ivan (author)The last years saw the diffusion of nano, pico and femto satellite missions launched by multiple entities thanks to the launch cost reduction and the electronics miniaturization. Such missions usually present limited capabilities in terms of precise orbit determination and extremely small radar and optical cross-sections. Often these missions...conference paper 2023

Meccanici, Floris (author), Karageorgos, Dimitrios (author), Heemskerk, Cock J.M. (author), Abbink, D.A. (author), Peternel, L. (author)Daily household tasks involve manipulation in cluttered and unpredictable environments and service robots require complex skills and adaptability to perform such tasks. To this end, we developed a teleoperated online learning approach with a novel skill refinement method, where the operator can make refinements to the initially trained skill...conference paper 2023

Avaei, S. (author), van der Spaa, L.F. (author), Peternel, L. (author), Kober, J. (author)Humans often demonstrate diverse behaviors due to their personal preferences, for instance, related to their individual execution style or personal margin for safety. In this paper, we consider the problem of integrating both path and velocity preferences into trajectory planning for robotic manipulators. We first learn reward functions that...journal article 2023

Celemin, Carlos (author), Kober, J. (author)In order to deploy robots that could be adapted by non-expert users, interactive imitation learning (IIL) methods must be flexible regarding the interaction preferences of the teacher and avoid assumptions of perfect teachers (oracles), while considering they make mistakes influenced by diverse human factors. In this work, we propose an IIL...journal article 2023
