(author), Silverman, D.T. (author)Objectives: To efficiently and reproducibly assess occupational diesel exhaust exposure in a Spanish case-control study, we examined the utility of applying decision rules that had been extracted from expert estimates and questionnaire response patterns using classification tree (CT) models from a similar US study. Methods: First, previously...article 2016

Nelisse, R.M.L. (author), Vrouwenvelder, A.C.W.M. (author)Article 13 of the EU Directive on minimum safety requirements for tunnels in the Trans-European Road Network states that a “risk analysis, where necessary, shall be carried out” [1]. In the Netherlands, the risk of death for road users in a tunnel (internal risk) is calculated with a model for quantitative risk analysis, which is called “QRA...conference paper 2016

van den Hout, A. (author), Fox, J.P. (author)Longitudinal data can be used to estimate the transition intensities between healthy and unhealthy states prior to death. An illness-death model for history of stroke is presented, where time-dependent transition intensities are regressed on a latent variable representing cognitive function. The change of this function over time is described by...article 2015

(author), Schwenn, M. (author), Johnson, A. (author), Armenti, K.R. (author), Silverman, D.T. (author), Yu, K. (author)Objectives: Rule-based expert exposure assessment based on questionnaire response patterns in population-based studies improves the transparency of the decisions. The number of unique response patterns, however, can be nearly equal to the number of jobs. An expert may reduce the number of patterns that need assessment using expert opinion, but...article 2015

Van Den Berg, Freek (author), Hooman, Jozef (author), Hartmanns, Arnd (author), Haverkort, Boudewijn R. (author), Remke, Anne (author)System designers need to have insight in the response times of service systems to see if they meet performance requirements. We present a high-level evaluation technique to obtain the distribution of services completion times. It is based on a high-level domain-specific language that hides the underlying technicalities from the system designer....bookPart 2015

(author)The EU Directive on the sustainable use of pesticides (EU128/2009/EC) requires European Member States to develop training activities targeting occupational exposure to pesticides, and communication material aimed at residents and bystanders. Risk perceptions, knowledge and attitudes associated with passive and occupational exposure to pesticide...article 2015

Roscoe, K. (author), Diermanse, F. (author), Vrouwenvelder, A.C.W.M. (author)Computing system reliability when system components are correlated presents a challenge because it usually requires solving multi-fold integrals numerically, which is generally infeasible due to the computational cost. In Dutch flood defense reliability modeling, an efficient method for computing the failure probability of a system of correlated...article 2015

Michels, S. (author), Hommersom, A. (author), Lucas, P.J.F. (author), Velikova, M. (author)Abstract Probabilistic logics combine the expressive power of logic with the ability to reason with uncertainty. Several probabilistic logic languages have been proposed in the past, each of them with their own features. We focus on a class of probabilistic logic based on Sato's distribution semantics, which extends logic programming with...article 2015

van Stralen, W.J.H. (author), Calvert, S.C. (author), Molin, E.J.E. (author)Weather conditions are widely acknowledged to contribute to the occurrence of congestion on motorway traffic by influencing both traffic supply and traffic demand. To the best of our knowledge, this is the first paper that explicitly integrates supply and demand effects in predicting the influence of adverse weather conditions on the probability...article 2015

Jolani, S. (author), Debray, T.P.A. (author), Koffijberg, H. (author), van Buuren, S. (author), Moons, K.G.M. (author)Individual participant data meta-analyses (IPD-MA) are increasingly used for developing and validating multivariable (diagnostic or prognostic) risk prediction models. Unfortunately, some predictors or even outcomes may not have been measured in each study and are thus systematically missing in some individual studies of the IPD-MA. As a...article 2015

Ellens, W. (author), Mandjes, M. (author), van den Berg, J.L. (author), Worm, D.T.H. (author), Błaszczuk, S. (author)This paper deals with the problem of inferring short time-scale fluctuations of a system's behavior from periodic state measurements. In particular, we devise a novel, efficient procedure to compute four interesting performance metrics for a transient birth-death process on an interval of fixed length with given begin and end states: the...article 2015

Weerheijm, J. (author), van der Voort, M.M. (author), Verreault, J. (author), van den Berg, A.C. (author)Tunnel accidents with transports of combustible liquefied gases may lead to explosions. Depending on the substance involved this can be a Boiling Liquid Expanding Vapour Explosion (BLEVE), a Gas Expansion Explosion (GEE) or a gas explosion. Quantification of the risk of these scenarios is important to take informed decisions on tunnel design and...conference paper 2015
