van der Kleij, R. (author), Hueting, T.F. (author), Schraagen, J.M.C. (author)Dynamic Positioning (DP) is a computer-controlled process to automatically keep a floating vessel at a specific position or to follow a pre-defined path (tracking) by using its own propellers and thrusters. The human supervisory controller has no direct need to constantly know what the status is of all parts of the automation and the system it...article 2018

Kayal, A. (author), van Riemsdijk, M.B. (author), Neerincx, M.A. (author), Brinkman, W.P. (author)Mobile location-sharing technology is increasingly being used by parents to locate their children. Research shows that these technologies may pose risks to important user values such as privacy and responsibility, while they aim to promote others such as family security. As a solution, we proposed the use of Social Commitment (SC) models for...article 2018

David, L.Z. (author), Schraagen, J.M.C. (author)A system’s continuous adaptability is a vital determinant of its safety. It is thus very important for a system to reach graceful extensibility, the ability to adapt in unexpected situations (Woods in Reliab Eng Syst Saf, https://doi.org/10.1016/j.ress.2015.03.018, 2015). Current methods to study patterns of adaptation have mostly focused on...article 2018

In this study, we investigated the systemic and liver-specific responses caused by a diet switch to a medium-fat (MF) diet in 24-month-old lifelong, CR-exposed mice. This study aimed to increase the knowledge base on dietary alterations of gerontological relevance. Nine...article 2018

(author)Wave propagation of electro-optical systems, lasers or imaging depends on the state of the atmosphere their beams are passing through. Fluctuations in the refractive index of air are responsible for signal attenuation and image degradation. This atmospheric effect is called optical turbulence and its strength is quantified by the structure...conference paper 2018

Verhoosel, J.P.C. (author), van Bekkum, M.A. (author)Nowadays, manufacturers must be increasingly flexible to quickly produce a high mix of on-demand, customer-specific, low volume product types. This requires flexible assembly lines with operators that are well-supported in their constantly changing assembly task, while producing high-quality, first-time-right, zero-defect products. Information...conference paper 2017

(author)To increase the collecting power and to improve the angular imaging resolution, space telescopes are evolving towards larger primary mirrors. The aerial density of the telescope mirrors needs to be kept low, however, to be compatible with the launch requirements. A light-weight (primary) mirror will introduce additional optical aberrations to...conference paper 2017
