(author)Field development planning activities involve decisions that entail multi-billion-dollar investments. Making right design choices is crucial to the techno-economic success of the project. In this paper we demonstrate how state-of-the-art numerical model-based optimization techniques can support asset teams in this complex decision-making process...conference paper 2023

van der Ploeg, C. (author), Smit, R. (author), Teerhuis, A. (author), Silvas, E. (author)Developing safe automated vehicles that can be proactive, safe, and comfortable in mixed traffic requires improved planning methods that are risk-averse and that account for predictions of the motion of other road users. To consider these criteria, in this article, we propose a nonlinear model-predictive trajectory generator scheme, which...conference paper 2022

Smit, R. (author), van der Ploeg, C. (author), Teerhuis, A. (author), Silvas, E. (author)The urban environment is amongst the most difficult domains for autonomous vehicles. The vehicle must be able to plan a safe route on challenging road layouts, in the presence of various dynamic traffic participants such as vehicles, cyclists and pedestrians and in various environmental conditions. The challenge remains to have motion planners...conference paper 2022

Sanchez, M.M. (author), Elfring, J. (author), Silvas, E. (author), van de Molengraft, R. (author)To operate safely, an automated vehicle (AV) must anticipate how the environment around it will evolve. For that purpose, it is important to know which prediction models are most appropriate for every situation. Currently, assessment of prediction models is often performed over a set of trajectories without distinction of the type of movement...conference paper 2022

Sharma, S. (author), van Lint, H. (author), Tavasszy, L. (author), Snelder, M. (author)This paper studies and compares the gap selection process of multiple vehicle classes (passenger cars, delivery vans, and trucks) within their discretionary lane changing activities. Given a trajectory or a sequence of gap selection decisions, we aim to predict whether a vehicle will change or keep a lane. For this purpose, we use a large...article 2022

Kamphuis, W. (author), Delahaij, R. (author), Duel, J. (author), Geuze, E. (author), Vermetten, E. (author)Veterans may report PTSD symptoms, years after their deployment. The aim of this study was to examine whether the presence of resilience resources before deployment, and the potential loss of these resources over time, are associated with the risk of PTSD symptoms five years post-deployment. The study focused on Dutch service members, deployed...article 2021

Barros, E.G.D. (author), Chitu, A. (author), Leeuwenburgh, O. (author)The general field development optimization problem is complex due to the potentially large number of controls of mixed type and discontinuities in the objective function related to varying numbers and types of wells being placed in a discretized grid. This may make the problem challenging or even unsuitable for certain types of optimization...article 2020

Mohan, R. (author), Silvas, E. (author), Stoutjesdijk, H. (author), Bruynincks, H. (author), de Jager, B. (author)Most human-centred robotic applications require robots to follow a certain pre-defined path. This makes the robot’s autonomous movements acceptable and predictable for humans. Planning a trajectory for the robot thus involves guiding it along this desired path. The classical approach of segmenting a path into multiple waypoints and tracking them...article 2020

Sanchez, M.M. (author), Silvas, E. (author), Pogosov, D. (author), Mocanu, D.C. (author)Vehicle-to-vehicle communication is a solution to improve the quality of on-road traveling in terms of throughput, safety, efficiency and comfort. However, road users that do not communicate their planned activities can create dangerous situations, so prediction models are needed to foresee and anticipate their motions in the drivable space....conference paper 2020

Katliar, M. (author), Olivari, M. (author), Drop, F.M. (author), Nooij, S. (author), Diehl, M. (author), Bülthoff, H.H. (author)This paper presents a method to simultaneously compute optimal simulator motions and simulator parameters for a predefined set of vehicle motions. The optimization can be performed with a model of human motion perception or sensory dynamics taken into account. The simulator dynamics, sensory dynamics, and optimality criterion are provided by the...article 2019

Boersma, M. (author)Hong Kong is residence to around 200,000 Filipina domestic workers who have migrated to the city in order to earn money for their families and futures. The employment of these migrants is organized through temporary two-year contracts. However, since many women stay for ‘multiple contracts’ in Hong Kong, their situation may be better...article 2019

op den Camp, O.M.G.C. (author), Uittenbogaard, J. (author), Bakker, B. (author)To increase traffic safety, systems are being implemented in vehicles that support drivers to avoid or mitigate collisions. Generally, these systems only provide a response to the driver in case of an imminent critical situation. Responses in the form of warning signals and brake or steering actuations are harsh, as they act in the last one to...conference paper 2018

Verhaegh, J. (author), Ploeg, J. (author), van Nunen, E. (author), Teerhuis, A. (author)This paper presents a method for trajectory control, based on feedback linearization to guide an Automatic Guided Vehicle (AGV). The novelty of this work, is the adaptation of a reference trajectory with respect to a desired velocity in real-time to avoid collisions using a time-scaling mechanism. Employing this mechanism, collision avoidance by...conference paper 2017

Lefeber, E. (author), Ploeg, J. (author), Nijmeijer, H. (author)We introduce a new way to look at the combined lateral and longitudinal control problem for platooning vehicles by studying these problems separately. The lateral control problem is approached as a path following problem in the spatial domain: based on the path of the preceding vehicle we determine a path for the following vehicle which...article 2017
