Nijkerk, M.D. (author), Gruber, J.M. (author), Boonacker, B. (author)We present a novel optical design tool that makes use of an evolutionary global optimization algorithm. The algorithm has several characteristics that make it well-suited for freeform optics design. With the design tool it is no longer necessary to make the distinction between paraxial degrees of freedom and degrees of freedom related to...conference paper 2018

(author)Active exoskeletons are potentially more effective and versatile than passive ones, but designing them poses a number of additional challenges. An important open challenge in the field is associated to the assistive strategy, by which the actuation forces are modulated to the user's needs during the physical activity. This paper addresses this...article 2018

Laan, C.M. (author), Barros, A.I. (author), Boucherie, R.J. (author), Monsuur, H. (author)In this chapter we consider a security game between an agent and an intruder to find optimal strategies for patrolling against illegal fishery. When patrolling large areas that consist of multiple cells, several aspects have to be taken into account. First, the current risk of the cells has to be considered such that cells with high risk are...bookPart 2018

van Lieshout, M. (author), Djafari, S. (author), Vermeulen, P. (author)Privacy is becoming a business asset. A number of developments contribute to this repositioning of privacy. In the first place, the extreme growth in the creation of data in the past few years makes the protection of persons in relation to the processing of their data more relevant. Secondly, the advent of new services that are largerly based on...other 2018

(author)The Zero Accident Vision (ZAV) is a promising approach developed in industry, but not so much addressed by the safety science research community. In a discussion paper in Safety Science (2013) a call was made for more research in this area. Three years later is a good time to take status of developments in this field. A first set of empirical...article 2017

Mentink, P. (author), Seykens, X. (author), Escobar Valdivieso, D. (author)To meet future emission targets, it becomes increasingly important to optimize the synergy between engine and aftertreatment system. By using an integrated control approach minimal fluid (fuel and DEF) consumption is targeted within the constraints of emission legislation during real-world operation. In such concept, the on-line availability of...article 2017

van Kooten, M. (author), Doelman, N.J. (author), Kenworthy, M. (author)Current high contrast imaging systems are limited at small angular separations, preventing the direct imaging of Earth-size exoplanets close to their host stars. One primary cause of this is the performance of the extreme adaptive optics (AO) system which is dominated by the servo-lag error at small angular separations. Prediction can be used to...conference paper 2017
