Duque, E.M.S. (author), Giraldo, J.S. (author), Vergara, P.P. (author), Nguyen, P.H. (author), van der Molen, A. (author), Slootweg, J. (author)This paper proposes a framework to identify, visualize, and quantify risk of potential over/under voltage due to annual energy consumption and PV generation growth. The stochastic modeling considers the following: (i) Active and reactive power profiles for distribution transformers, dependent on annual energy consumption and activity in the...article 2023

Maljaars, J. (author), Rozsas, A. (author), Walters, C.L. (author), Slot, H.M. (author)The failure assessment line (FAL) describes the interaction between plastic failure and fracture of flawed steel components subjected to tension or bending. This paper quantifies the model uncertainty of the FAL as provided in the internationally used British Standard BS 7910:2019 by comparing the assessment with the actual failure load of 82...article 2022

(author)Surface movement can be induced by many human subsurface activities: production of natural gas, geothermal heat extraction, ground water extraction, phreatic groundwater level lowering, storage of natural gas and CO2. In this manuscript, we focus on subsidence caused by gas production. While geological interpretations, seismic campaigns and flow...article 2022

(author)Rain-induced leading-edge erosion of wind turbine blades is associated with high repair and mainte nance costs. For efficient operation and maintenance, erosion models are required that provide estimates of blade coating lifetime at a real scale. In this study, a statistical rainfall model is established that de scribes probabilistic...article 2022

Maljaars, J. (author), Misiek, T. (author)Many steel rope systems are subjected to fluctuating tensile loads and therefore can fail due to fatigue. Available fatigue test data indicate that rope diameter, mean stress, socket type, lay angle and rope length influence the fatigue resistance. Most of the tests were terminated before full failure of the ropes. This paper shows that the test...article 2021

Steenbergen, R.D.J.M. (author)Until recently earthquakes were not taken into account in the Dutch Building Decree and other Dutch building regulations. Although in 1992, an earthquake happened in Roermond with a magnitude of 5.8 on the Richter scale which damaged buildings, this was not seen by the law makers as an argument for the introduction of regulations for earthquake...article 2021

Nadolski, V. (author), Rózsás, Á. (author), Sýkora, M. (author)Partial factors are commonly based on expert judgements and on calibration to previous design formats. This inevitably results in unbalanced structural reliability for different types of construction materials, loads and limit states. Probabilistic calibration makes it possible to account for plentiful requirements on structural performance,...article 2019

Velikova, M. (author), Ypma, A. (author), Bratosin, C. (author), Lemmen, V. (author), van Wijk, R.J. (author)Controlling the operations and resolving product performance issues in today’s high-tech production systems, such as semiconductor fabs, becomes a cumbersome task, even for experienced field engineers. To address the pressing need for assisted diagnostics approaches, in this paper we propose a model-based step-wise methodology, based on domain...conference paper 2019

(author), Marcomini, A. (author)The increasing use of engineered nanomaterials (ENMs) in nano-enabled products (NEPs) has raised societal concerns about their possible health and ecological implications. To ensure a high level of human and environmental protection it is essential to properly estimate the risks of these new materials and to develop adequate risk management...article 2019

(author), Kruizinga, A.G. (author)One of the input parameters in food allergy risk assessment is the amount of a given food consumed at an eating occasion. There is no consensus on how to use food consumption data when assessing the risk from unintended allergen presence in food products. A sensitivity analysis was performed to establish the optimal food consumption estimate for...article 2019

(author)We present a study of border surveillance systems for automatic threat estimation. The surveillance systems should allow border control operators to be triggered in time so that adequate responses are possible. Examples of threats are smuggling, possibly by using small vessels, cars or drones, and threats caused by unwanted persons (e.g....conference paper 2019

Maljaars, J. (author), Bonet, E. (author), Pijpers, P.J.M. (author)Steel orthotropic decks in bridges and ferries have shown to be prone to fatigue cracking. A typical fatigue crack observed in these structures initiates at the root of the weld between the deck plate and stringer and grows into the deck plate. Due to limited fatigue test data available and the deviating characteristics of this type of crack as...article 2018

Meinen, N.E. (author), Steenbergen, R.D.J.M. (author)To assess the reliability of a structure, reliability based codes such as EN1990:2002 allow for the application of full-probabilistic methods and semi-probabilistic methods (i.e. the partial factor method). In principle, both methods should be equivalent and lead to (approximately) the same reliability level. In this study, this equivalence is...article 2018

(author)Food allergic subjects need to avoid the allergenic food that triggers their allergy. However, foods can also contain unintended allergens. Food manufacturers or authorities need to perform a risk assessment to be able to decide if unintended allergen presence constitutes a risk to food allergic consumers. One of the input parameters in risk...article 2017
