Anderson, K.S. (author), Visser, Denise (author), Mannen, Jan-Willem (author), Jiang, Yuxiang (author), van Deursen, A. (author)Background: Applying Continuous Experimentation on a large scale is not easily achieved. Although the evolution within large tech organisations is well understood, we still lack a good understanding of how to transition a company towards applying more experiments. Objective: This study investigates how practitioners define, value and apply...conference paper 2022

Antonopoulos, S. (author), Visser, K. (author), Kalikatzarakis, Miltiadis (author), Reppa, V. (author)This paper proposes an advanced shipboard energy management strategy (EMS) based on model predictive control (MPC). This EMS aims to reduce mission-scale fuel consumption of ship hybrid power plants, taking into account constraints introduced by the shipboard battery system. Such constraints are present due to the boundaries on the battery...journal article 2021

Sui, Congbiao (author), de Vos, P. (author), Stapersma, D. (author), Visser, K. (author), Ding, Yu (author)Hybrid propulsion and using liquefied natural gas (LNG) as the alternative fuel have been applied on automobiles and some small ships, but research investigating the fuel consumption and emissions over the total voyage of ocean-going cargo ships with a hybrid propulsion and different fuels is limited. This paper tries to fill the knowledge...journal article 2020

Borst, C. (author), Visser, Roeland M. (author), van Paassen, M.M. (author), Mulder, Max (author)In many work domains, the push toward higher levels of automation raises the concern of diminishing human expertise. Ecological interfaces could help operators in retaining and potentially even in acquiring expertise as they are hypothesized to lead to a deeper understanding of the work domain. This study explores the short-term impact of...journal article 2019

van Biert, L. (author), Godjevac, M. (author), Visser, K. (author), Aravind, P.V. (author)Direct internal reforming enables optimal heat integration and reduced complexity in solid oxide fuel cell (SOFC)systems, but thermal stresses induced by the increased temperature gradients may inflict damage to the stack. Therefore, the development of adequate control strategies requires models that can accurately predict the temperature...journal article 2019

Foortse, Bjorn (author), Visser, P.J. (author), Bisschop, Rik (author), van Rhee, C. (author)Significant reduction of the rate of erosion of a sand bed is obtained when sand is mixed with a small amount of bentonite. In previous experiments this behaviour has already been shown for relatively low flow velocities. In this case, the erosion process is dominated by grain-by-grain erosion, which is characterised by low ratios of the...journal article 2019

Geertsma, R.D. (author), Visser, K. (author), Negenborn, R.R. (author)Shipping urgently needs to reduce its impact on the environment, both due to CO<sub>2</sub>, NO<sub>x</sub> and particulate matter (PM) emissions and due to underwater noise. On the other hand, multifunction ships such as offshore support vessels, anchor handling and towing vessels, naval vessels and wind farm construction and support vessels...journal article 2018

Geertsma, R.D. (author), Negenborn, R.R. (author), Visser, K. (author), Hopman, J.J. (author)The recent trend to design more efficient and versatile ships has increased the variety in hybrid propulsion and power supply architectures. In order to improve performance with these architectures, intelligent control strategies are required, while mostly conventional control strategies are applied currently. First, this paper classifies...review 2017

Geertsma, R.D. (author), Negenborn, R.R. (author), Visser, K. (author), Loonstijn, M.A. (author), Hopman, J.J. (author)Ships, in particular service vessels, need to reduce fuel consumption, emissions and cavitation noise while maintaining manoeuvrability and preventing engine overloading. Diesel mechanical propulsion with controllable pitch propellers can provide high fuel efficiency with good manoeuvrability. However, the conventional control strategy with...journal article 2017

Visser, J. (author)The PROCRU (Procedure Oriented Crew) model has been developed for the analysis and modeling of flight crew procedures during an ILS approach. The model's specific capability concerns the generation of "timelines" of the necessary actions to be carried out by each crew member during the approach. Besides, also the corresponding timelines for...report 1987
