van Kampen, J. (author), Boon, J. (author), van Sint Annaland, M. (author)Steam adsorption enhanced reaction processes are a promising process intensification for many types of reactions, where water is formed as a byproduct. To assess the potential of these processes, adequate models are required that accurately describe water adsorption, particularly under the desired elevated temperatures and pressures. In this...article 2020

Saberi, A.K. (author), Hegge, J. (author), Fruehling, T. (author), Groote, J.F. (author)The ISO 26262 standard addresses system failures and the need to mitigate them safely. However, the standard is only implicit regarding the safety of the intended functionality. One should concede that a system without failures, operating in the specified design boundaries should be safe. None the less, the new ISO/PAS 21448 standard on Safety...conference paper 2020

Marko, N. (author), Vasenev, A. (author), Striecks, C. (author)In the past several years, autonomous driving turned out tobe a target for many technical players. Automated driving requires newand advanced mechanisms to provide safe functionality and the increased communication makes automated vehicles more vulnerable to attacks. Security is already well-established in some domains, such as the IT sector,...conference paper 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

(author)Drivers struggle to understand how, and when, to safely use their cars' complex automated functions. Training is necessary but costly and time consuming. A Digital In-Car Tutor (DIT) is proposed to support drivers in learning about, and trying out, their car automation during regular drives. During this driving simulator study, we investigated...article 2020

(author)Autonomous vehicles use Electronic Control Units running complex software to improve passenger comfort and safety. To test safety of in-vehicle electronics, the ISO 26262 standard on functional safety recommends using fault injection during component and system-level design. A Fault Injection Framework (FIF) induces hard-to-trigger hardware and...conference paper 2019

Venkita, S.R. (author), Willemsen, D. (author), Alirezaei, M. (author), Nijmeijer, H. (author)One of the main safety concerns associated with semi-autonomous vehicles is the sharing of control between a human driver and an autonomous driving system. Even with an attentive driver, such switches in control may pose a threat to the safety of the driver and the surrounding vehicles. The aim of this study is to develop an indicator that can...article 2019

de Bruin, G.J. (author), Veenman, C.J. (author), van den Herik, H.J. (author), Takes, F.W. (author)This paper examines the co-driving behavior of truck drivers using network analysis. From a unique spatiotemporal dataset encompassing more than 10 million measurements of trucks passing 17 different highway locations in the Netherlands, we extract a so-called co-driving network. In this network, nodes are truck drivers and edges represent pairs...conference paper 2019

(author), Westerhof, E. (author), de Baar, M.R. (author)The successful use of a tokamak for generating fusion power requires an active control of magnetic instabilities, such as neoclassical tearing modes (NTMs). Commonly, the NTM location is determined using electron cyclotron emission (ECE) and this is used to apply electron cyclotron heating (ECH) on the NTM location. In this paper, an inline ECE...article 2019

Constrained multivariable extremum-seeking for online fuel-efficiency optimization of Diesel enginesvan der Weijst, R. (author), van Keulen, T. (author), Willems, F.P.T. (author)This work presents a new method for online fuel-efficiency optimization of Diesel engines, using constrained extremum-seeking. A two-input optimization problem, which is suitable for extremum-seeking, is integrated into a tracking control system. As a result, both air-path and fuel-path actuators are used for tracking and extremum-seeking. A key...article 2019
