Klok, J.W.A. (author), Groenewegen, Jessica (author), Temmerman, Olivier (author), Van Straten, Niels (author), van Straten, Bart (author), Dankelman, J. (author), Horeman, T. (author)Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is complex, particularly the distal cement plug. This removal procedure often increases the risk...journal article 2024

Ewald, Vincentius (author)One of the classical solutions to maintain the aircraft structural integrity is to rely on the analysis of non-destructive testing (NDT) inspector with various inspection methods. However, it is relatively expensive in matter of time and costs to train human resources until the certification is reached. Further, in majority of the cases of...doctoral thesis 2023

Xin, Jianbin (author), Wu, Xuwen (author), D'Ariano, Andrea (author), Negenborn, R.R. (author), Zhang, Fangfang (author)Most of the existing path planning methods of automated guided vehicles (AGVs) are static. This paper proposes a new methodology for the path planning of a fleet of AGVs to improve the flexibility, robustness, and scalability of the AGV system. We mathematically describe the transport process as a dynamical system using an ad hoc mixed...journal article 2023

Gul, F.C. (author), Moradi, M. (author), Benedictus, R. (author), HADJRIA, RAFIK (author), LUGOVTSOVA, YEVGENIYA (author), Zarouchas, D. (author)Under in-plane compressive load conditions, the growth of a delamination initially induced by an impact can be followed by a fast growth after a threshold level, which leads to a catastrophic failure in composite structures. To avoid reaching this critical level, it is essential to uncover the delamination size and growth pattern in real time....conference paper 2023

Moradi, M. (author), Gul, F.C. (author), Chiachío, Juan (author), Benedictus, R. (author), Zarouchas, D. (author)A health indicator (HI) serves as an intermediary link between structural health monitoring (SHM) data and prognostic models, and an efficient HI should meet prognostic criteria, i.e., monotonicity, trendability, and prognosability. However, designing a proper HI for composite structures is a challenging task due to the complex damage...conference paper 2023

Galiana, Shankar (author), Moradi, M. (author), Wierach, Peter (author), Zarouchas, D. (author)Acousto-ultrasonic composite transducers (AUCT), which are made of piezoceramic materials embedded in a reinforced polymeric matrix, are promising for the health monitoring of composite structures. However, when they are integrated into highly loaded thermoplastic composite structures, ensuring proper joining properties is a challenge. The...conference paper 2023

Xin, Jianbin (author), Wei, Liuqian (author), D'Ariano, Andrea (author), Zhang, Fangfang (author), Negenborn, R.R. (author)Operations of Automated Guided Vehicles (AGVs) are desired to be more energy-efficient while maintaining high transport productivity, motivated by the green production requirements. This paper investigates a new energy-efficient planning problem for determining conflict-free paths of the AGVs in its transport roadmap. In this problem, the...journal article 2023

Kon, Johan (author), de Vos, Naomi (author), Bruijnen, Dennis (author), van de Wijdeven, Jeroen (author), Heertjes, Marcel (author), Oomen, T.A.E. (author)Tracking performance of physical-model-based feedforward control for interventional X-ray systems is limited by hard-to-model parasitic nonlinear dynamics, such as cable forces and nonlinear friction. In this paper, these nonlinear dynamics are compensated using a physics-guided neural network (PGNN), consisting of a physical model, embedding...journal article 2023

Rommers, J. (author)The moving parts in a mechanical device often rely on rolling or sliding contacts such as in ball bearings to gain motion. These suffice in many applications, but the friction inherent to their working principle limits their motion repeatability and thereby their precision. Flexure mechanisms are a popular alternative in the field of precision...doctoral thesis 2022

Corstanje, M.A. (author), van der Meulen, F.H. (author), Schauer, M.R. (author)A continuous-time Markov process X can be conditioned to be in a given state at a fixed time T>0 using Doob's h-transform. This transform requires the typically intractable transition density of X. The effect of the h-transform can be described as introducing a guiding force on the process. Replacing this force with an approximation...journal article 2022
