Verriet, J. (author), van der Sanden, B. (author), van der Veen, G. (author), van Splunter, A. (author), Lousberg, S. (author), Hendriks, M. (author), Basten, T. (author)Product family development facilitates reuse across all phases of systems engineering; in case of model-based systems engineering, this reuse involves the models as well. Introducing a model-based way of working is challenging, especially for product family development. This paper describes a case of introducing a modelbased way of working in...conference paper 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

Hulsbosch-Dam, C.E.C. (author), Spruijt, M.P.N. (author), Necci, A. (author), Cozzani, V. (author)A model was developed to calculate the particle size distribution following the release of pressurised supercritical CO 2. The model combines several sub-models for the different stages of jet break-up and specifically addresses the possible formation of solid particles, which is important for CO 2 releases. The model was validated using...article 2012

(author), TNO Bouw en Ondergrond (author)The performance of a Land Use Regression (LUR) model and a dispersion model (URBIS - URBis Information System) was compared in a Dutch urban area. For the Rijnmond area, i.e. Rotterdam and surroundings, nitrogen dioxide (NO<sub>2</sub>) concentrations for 2001 were estimated for nearly 70 000 centroids of a regular grid of 100 × 100 m.A LUR...article 2010

(author), TNO Bouw en Ondergrond (author)The oceans are a major source for particles that play an important role in many atmospheric processes. In Europe sea salt may contribute significantly to particulate matter concentrations. We have compiled sodium concentration data as a tracer for sea salt for 89 sites in Europe to provide more insight in the distribution of sea salt across...article 2010

van Zon, A.T. (author), Roy Chowdhury, K. (author), TNO Defensie en Veiligheid (author)In this study, a regional scale gravity data set has been inverted to infer the structure (topography) of the top of the basement underlying sub-horizontal strata. We apply our method to this real data set for further proof of concept, validation and benchmarking against results from an earlier forward modelling done elsewhere.Our aim is to...article 2010

Boltjes, B. (author), van den Oever, J. (author), Zhang, S. (author), TNO Informatie- en Communicatietechnologie (author)TNO has formulated the ambition of founding a basis for the development of flexible multi-data source and multi-application (ad hoc) sensor networks. These networks are envisioned on a scale that is beyond networks for specific and separate sensor networks. These separate networks need in the future to be combined intelligently in order to...conference paper 2008

TNO Bouw en Ondergrond (author), van Dijk, T.A.G.P. (author), Lindenbergh, R.C. (author), Egberts, P.J.P. (author)The superimposition of rhythmic bed forms of different spatial scales is a common and natural phenomenon on sandy seabeds. The dynamics of such seabeds may interfere with different offshore activities and are therefore of interest to both scientists and offshore developers. State-of-the-art echo sounding accuracy allows for the analysis of bed...article 2008
