Mehrabani, B.B. (author), Erdmann, J. (author), Sgambi, L. (author), Snelder, M. (author)One of the potential capabilities of Connected and Autonomous Vehicles (CAVs) is that they can have different route choice behavior and driving behavior compared with human Driven Vehicles (HDVs). This will lead to mixed traffic flow with multiple classes of route choice behavior. Therefore, it is crucial to solve the multiclass Traffic...conference paper 2023

Xu, Q. (author), Hofmeyer, H. (author), Maljaars, J. (author), van Herpen, R.A.P. (author)This paper presents two full-scale fire resistance tests of sandwich panels with connections, to verify one way coupled fire-structure simulations. The heat transfer simulations agree well with the tests, however, the structural response simulations show some differences compared to the start of the first test, which is a sandwich panel façade....conference paper 2022

Snijder, H.H. (author), Knipping, J.B.N. (author), Maljaars, J. (author), Teeuwen, P.A. (author)Capacity design for bolted connections in tension means that yielding of the gross cross-section is decisive over the ultimate resistance of the net cross-section. If the requirement for capacity design is met, ductile connection behavior is achieved, and brittle failure is avoided. However, in many practical cases the bolt holes are too large...article 2022

Raftopoulou, M. (author), Litjens, R. (author), van Mieghem, P. (author)In this paper, we focus on the link density in random geometric graphs (RGGs) with a distance-based connection function. After deriving the link density in D dimensions, we focus on the two-dimensional (2D) and three-dimensional (3D) space and show that the link density is accurately approximated by the Fréchet distribution, for any rectangular...article 2022

Deschle, N. (author), van Ark, E.J. (author), van Gijlswijk, R. (author), Janssen, R. (author)Pollutant emissions have been a topic of interest in the last decades. Not only environ mentalists but also governments are taking rapid action to reduce emissions. As one of the main contributors, the transport sector is being subjected to strict scrutiny to ensure it complies with the short and long-term regulations. The measures imposed by...article 2022

DiBrita, N.S. (author), Eledlebi, K. (author), Hilmann, H. (author), Culley, L. (author), Isakovic, A.F. (author)Temporal network analysis and time evolution of network characteristics are powerful tools in describing the changing topology of dynamic networks. This paper uses such approaches to better visualize and provide analytical measures for the changes in performance that we observed in Voronoi-type spatial coverage, particularly for the example of...article 2022

Spataru, A. (author), van Dommelen, P. (author), Arnaud, L. (author), Le Masne, Q. (author), Quarteroni, S. (author), Koledova, E.B. (author)Background. Our aim was to develop a machine learning model, using real-world data captured from a connected auto-injector device and from early indicators from the first 3 months of treatment, to predict sub-optimal adherence to recombinant human growth hormone (r-hGH) in patients with growth disorders. Methods. Adherence to r-hGH treatment was...article 2022

(author)Background: Recombinant human growth hormone (rhGH) therapy is an effective treatment for children with growth disorders. However, poor outcomes are often associated with suboptimal adherence to treatment. Objective: The easypod connected injection device records and transmits injection settings and dose data from patients receiving rhGH. In...article 2022

Xu, Q. (author), Hofmeyer, H. (author), Maljaars, J. (author)A two-scale finite element model is proposed to improve two-way coupled fire-structure simulations. The model consists of (i) a global-scale model, which accounts for the structure, and (ii) a small-scale model for each connection. Structural parts on the global scale are connected by spring elements, which stiffness properties are updated by...conference paper 2021

Maljaars, J. (author), Euler, M. (author)Bolts and bolted connections are frequently used in civil engineering steel structures. This paper presents a meta study where a few thousand fatigue tests on these elements are evaluated. The evaluation reveals that current specifications in design standards need updating to account for the relevant stress parameter and production methods. This...article 2021

den Otter, C. (author), Maljaars, J. (author)Bolted connections are applied in many aluminium structures. Stainless steel bolts are often preferred over carbon steel bolts in aluminium connections to prevent galvanic corrosion. However, current design standards and guidelines do not allow for using preloaded stainless steel bolts in slip resistant connections, mainly because of a lack of...article 2020

Phillipson, F. (author)In vehicular ad-hoc networks a path has to be found to send a message from one vehicle to another vehicle. This path has to have a connectivity rate that is high enough to obtain a high probability of arrival of the message. In other approaches, this path is based of current, static information of the distribution of cars. In this paper we...conference paper 2019
