Katliar, M. (author), Olivari, M. (author), Drop, F.M. (author), Nooij, S. (author), Diehl, M. (author), Bülthoff, H.H. (author)This paper presents a method to simultaneously compute optimal simulator motions and simulator parameters for a predefined set of vehicle motions. The optimization can be performed with a model of human motion perception or sensory dynamics taken into account. The simulator dynamics, sensory dynamics, and optimality criterion are provided by the...article 2019

Bruijns, L.A.M. (author), Phillipson, F. (author), Sangers, A. (author)We provide a method to obtain a User Equilibrium in a transportation network, in which we transport containers for multiple agents. The User Equilibrium solution is defined as the solution wherein each agent can travel via their cheapest paths possible, and no agent is harmed by the route choice of other agents. The underlying model used is the...conference paper 2019

Saffre, F. (author), Gianini, G. (author), Hildmann, H. (author), Davies, J. (author), Bullock, S. (author), Damiani, E. (author), Deneubourg, J.L. (author)We investigate the hypothesis that long-term memory in populations of agents can lead to counterproductive emergent properties at the system level. Our investigation is framed in the context of a discrete, one-dimensional road-traffic congestion model: we investigate the influence of simple cognition in a population of rational commuter agents...article 2019

van Kooten, M. (author), Doelman, N.J. (author), Kenworthy, M. (author)For high-contrast imaging systems, the time delay is one of the major limiting factors for the performance of the extreme adaptive optics (AO) sub-system and, in turn, the final contrast. The time delay is due to the finite time needed to measure the incoming disturbance and then apply the correction. By predicting the behavior of the...article 2019

Constrained multivariable extremum-seeking for online fuel-efficiency optimization of Diesel enginesvan der Weijst, R. (author), van Keulen, T. (author), Willems, F.P.T. (author)This work presents a new method for online fuel-efficiency optimization of Diesel engines, using constrained extremum-seeking. A two-input optimization problem, which is suitable for extremum-seeking, is integrated into a tracking control system. As a result, both air-path and fuel-path actuators are used for tracking and extremum-seeking. A key...article 2019

Xia, L. (author), Willems, R. (author), Jager, B.D. (author), Willems, F. (author)Fuel efficiency optimization and emission reduction have become essential parts of engine research, due to the growing demand for environmental protection. In this paper, a computationally efficient optimization method has been applied to maximize the fuel efficiency under constraints of maximum pressure rise rate and various pollutant emissions...conference paper 2019

Laan, C.M. (author), Barros, A.I. (author), Boucherie, R.J. (author), Monsuur, H. (author), Timmer, J. (author)In this paper, we introduce partially observable agent-intruder games (POAIGs). These games model dynamic search games on graphs between security forces (an agent) and an intruder given possible (border) entry points and high value assets that require protection. The agent faces situations with dynamically changing, partially observable...article 2019

de Ridder, F. (author), Neumann, N.M.P. (author), Veugen, P.J.M. (author), Kooij, R. (author)In this work, we consider the following problem: given a graph, the addition of which single edge minimises the effective graph resistance of the resulting (or, augmented) graph. A graph’s effective graph resistance is inversely proportional to its robustness, which means the graph augmentation problem is relevant to, in particular, applications...conference paper 2019

Kolodziejak, D.P.H. (author), Pham, T.H. (author), Hofman, T. (author), Wilkins, S. (author)This paper develops an optimization framework to minimize the Total Cost of Ownership (TCO) for Plug-in Hybrid Electric Vehicles (PHEVs). In this paper, TCO is the summation of operational and main vehicle powertrain components cost. The developed optimization framework is formulated via combining convex optimization and Dynamic Programming...conference paper 2019

Barros, E.G.D. (author), van den Hof, P.M.J. (author), Jansen, J.D. (author)The exploitation of subsurface hydrocarbon reservoirs is achieved through the control of production and injection wells (i.e., by prescribing time-varying pressures and flow rates) to create conditions that make the hydrocarbons trapped in the pores of the rock formation flow to the surface. The design of production strategies to exploit these...article 2019
