Nijenhuis, J.R. (author), Jonker, W.A. (author), Kamphues, F.G. (author)TNO, in close cooperation with Demcon, has designed the Laser Projection Subsystem (LPS) for ESO’s Extremely Large Telescope (ELT). The ELT LPS will consist of up to 8 laser projection subunits. The design is based on the Four Laser Guide Star Facility (4LGSF), built for the ESO Very Large Telescope (VLT) (5). The VLT AO system has been...conference paper 2022

Nijenhuis, J.R. (author), van der Heiden, N. (author), Jonker, W.A. (author)TMT will be a telescope with 492 segments making up the primary mirror. Each of these segments is supported with a highly sophisticated Segment Support Assembly (SSA) and each of them is to be tested for acceptance using a tool called SMATT. This tool will be mounted on top of each SSA and provides the load distribution applied to its 27 support...conference paper 2022

Diallo, M. (author), Akesson, B. (author), Bera, D. (author), Begeer, R. (author)There are many classes of Petri nets for describing communicating systems. Some of these guarantee important properties, such as termination in the case of portnets. There are also many methods and tools available for their analysis and synthesis. However, when developing new methods, or benchmarking against existing ones, it is often helpful to...conference paper 2021

(author)In addition to the desired aesthetical properties, a coating is applied to protect against weathering. A coating prevents moisture accumulation in wood by reducing the water uptake into the wood by its barrier function. The studies in the coating permeability has gained interest with the shift towards waterborne coatings, which make coatings...article 2019

Zwaveling-Soonawala, N. (author), Trotsenburg, A.S. (author), Verkerk, P.H. (author)Context. In central hypothyroidism (CeH) free thyroxine (FT4) concentrations are low while TSH concentrations may be low, normal or even slightly elevated due to reduced bioactivity. Congenital CeH (CCeH) may be isolated or part of multiple pituitary hormone deficiency (MPHD). Objective. To test our hypotheses that (1) TSH concentrations have a...article 2018

Goede, H.A. (author), Ploeg, D. (author), Schinkel, J.M. (author)The development of a dermal exposure model is a challenge because of the complexity of dermal exposure processes on one hand, and the scarcity of good quality and contextually-rich dermal exposure measurements. Dermal exposure modelling is further complicated by the difficulty of measuring dermal exposure due to the lack of standardised methods ...report 2018
