M. Sanchez, M. (author), Pogosov, D. (author), Silvas, E. (author), Mocanu, D.C. (author), Elfring, J. (author), van de Molengraft, R. (author)An automated vehicle (AV) must always have a correct representation of the drivable space to position itself accurately and operate safely. To determine the drivable space, current research focuses on single sources of information, either using pre-computed high-definition maps, or mapping the environment online with sensors such as LiDARs or...article 2022

In short term, theserange from achieving lowest ownership costs to preventing monopolies. In long term, project developersfocus on how uncertainties of design parameters (e.g. demand/supply, heat prices) affect the grid designand, ultimately, the business case...article 2020

Gross, D. (author), Jansen, N. (author), Perez, G.A. (author), Raaijmakers, S. (author)We give a formal verification procedure that decides whether a classifier ensemble is robust against arbitrary randomized attacks. Such attacks consist of a set of deterministic attacks and a distribution over this set. The robustness-checking problem consists of assessing, given a set of classifiers and a labelled data set, whether there exists...conference paper 2020

Poort, J.P. (author), Shoeibi Omrani, P.S. (author), Vecchia, A.L. (author), Visser, G. (author), Janzen, M. (author), Koenes, J. (author)Detection of production and well events is crucial for planning of production and operational strategies. Event detection is especially challenging in mature fields in which various off-normal events might occur simultaneously. Manual detection of these events by an engineer is a tedious task and prone to errors. On the other hand, abundance of...conference paper 2020

Ramaswamy, K.R. (author), Fonseca, R.M. (author), Leeuwenburgh, O. (author), Siraj, M.M. (author), van den Hof, P.M.J. (author)We are concerned with the efficiency of stochastic gradient estimation methods for large-scale nonlinear optimization in the presence of uncertainty. These methods aim to estimate an approximate gradient from a limited number of random input vector samples and corresponding objective function values. Ensemble methods usually employ Gaussian...article 2020

Ortega del Vecchyo, M.R. (author), Phillipson, F. (author), Sangers, A. (author)Multiple different attributes are important in the container-to-mode assignment in a transportation network. This paper proposes an interactive multi-objective optimisation approach for planners of those transportation networks. This approach offers a range of solutions according to her/his preferences, and offers the opportunity to seek for new...conference paper 2019

Medina, R. (author), Valencia, J. (author), Stuijk, S. (author), Goswami, D. (author), Basten, T. (author)Pipelined image-based control uses parallel instances of its image-processing algorithm in a pipelined fashion to improve the quality of control. A performance-oriented control design improves the controller settling time with each additional processing resource, which creates a resources-performance trade-off. In real-life applications, it is...article 2019

(author)In this paper we present our results, challenges and learnings, over a two-year period wherein robust multi-objective optimization was applied at the Mariner asset which is being currently developed. Many different problems were solved with different objectives. These problems were formulated based on the phases of planning and development at...conference paper 2019

Willems, F. (author), van Gompel, P. (author), Seykens, X. (author), Wilkins, S. (author)This work gives an outlook on the potential of automated driving functions (ADFs) to reduce real-world CO2 and pollutant emissions for heavy-duty powertrains. Up to now, ADF research mainly focuses on increased traffic safety, driver comfort, and road capacity. Studies on emissions are lacking. By taking the driver out-of-the-loop, cycle-to...conference paper 2019

Kanev, S. (author)Active wake control (AWC) is an operational strategy for wind farms that aims at reducing the negative effects of wakes behind wind turbines on the power production and mechanical loads at the wind turbines' downstream. For a given wind direction, the strategy relies on collaborative control of the machines within each row of turbines that...article 2019

Behrouzian, A. (author), Goswami, D. (author), Basten, A.A. (author)Feedback control applications are robust to occasional deadline misses. This opens up the possibility of saving scarce (computation and communication) resources on embedded platforms. Stability and performance requirements of a control loop impose restrictions on acceptable patterns of deadline misses (e.g., not too many misses in a row). Such...conference paper 2018
