Eekhout, I. (author), van Buuren, S. (author), Visser, B. (author), Bink, M.C.A.M. (author), Huisman, A. (author)Intensive longitudinal data can be used to explore important associations and patterns between various types of inputs and outcomes. Nonlinear relations and irregular measurement occasions can pose problems to develop an accurate model for these kinds of data. This paper focuses on the development, fitting and evaluation of a prediction model...article 2023

(author), Goede, H. (author), Machera, K. (author), Gerritsen-Ebben, R. (author)For many work situations only insufficient exposure data are available to perform proper risk assessment. Because measuring worker exposure can be time consuming and resource intense, the availability of reliable exposure models is important when performing risk assessments. However, the development and improvement of exposure models are...article 2020

Bijl, P. (author), Hogervorst, M.A. (author)Image-based Electro-Optical system simulation including an end-to-end performance test is a powerful tool to characterize a camera system before it has been built. In particular, it can be used in the design phase to make an optimal trade-off between performance on the one hand and SWaPC (Size, Weight, Power and Cost) criteria on the other....conference paper 2019

(author)Hyperspectral imaging sensors acquire images in a large number of spectral bands, unlike traditional electro-optical and infrared sensors which sample only one or few bands. Hyperspectral mosaic sensors acquire an image of all spectral bands in one shot. Using a patterned array of spectral filters they measure different wavelength bands at...conference paper 2019

van Lieshout, M.J. (author), Emmert, S.B. (author)The right to privacy is enshrined in the European charter of fundamental rights. The right to data protection is a relatively novel right, also enshrined in the same European charter. While these rights seem to focus on a defensive and protective approach, they also give rise to a positive and constructive interpretation. The GDPR may act as...conference paper 2018

(author), Schutte, K. (author), Dijk, J. (author)Detecting maritime targets with electro-optical sensors is an active area of research. One current trend is to automate target detection through image processing or computer vision. Automation of target detection will decrease the number of people required for lower-level tasks, which frees capacity for higher-level tasks. A second trend is that...conference paper 2018

(author)Process models are schematic representations of business processes and support analysis for process redesign. A process model may be enhanced with additional information to further improve its analytical value (e.g. costs, throughput times, etc.). To support analysis of human factors in manufacturing processes, this paper introduces a new...conference paper 2018
