Li, J. (author), van Zuylen, H.J. (author), van der Horst, E. (author)Driver behavior in China shows remarkable differences from that in western countries. In this study, six focus groups were organized to investigate Chinese drivers’ attitudes, expectations, intended actions, their preferences, and habits in different situations in urban areas. The outcomes show that there are important opportunities to improve...conference paper 2014

Magan, Christopher (author), Coenders, J.L. (author), Huijben, F (author), Nijsse, R. (author), van der Horst, A.Q.C. (author)This paper presents a design for a topology-optimised concrete floor slab, of which the structural optimisation process is guided by manufacturability constraints from a vacuumatic formwork. Ihe design has been obtained using an open-source, tliree-dimensional topology optimisation algorithm. Traditional floor systems are cost-optimised but can...conference paper 2016

(author), van Wijngaarden, Dennis (author), Meulenbeld, Joost (author), van Hecke, K.G. (author)Enlarging the flight envelope of aircraft has been a goal since the beginning of aviation. But requirements to fly very fast and to hover are conflicting. During the design of the DelftaCopter, a tail-sitter hybrid UAV with a single large rotor for lift in hover and propulsion in forward flight, the design of the rotor needs to properly balance...conference paper 2018

Mancinelli, A. (author), van der Horst, E. (author), Remes, B.D.W. (author), Smeur, E.J.J. (author)This paper presents a modular autopilot framework for Unmanned Aerial Vehicles (UAVs) that addresses the limitations of modern flight controllers. The framework utilizes separate and external subsystems for actuator control and the resolution of the Control Allocation problem. The actuator subsystem, implemented on a Teensy 4.0 microcontroller,...conference paper 2023

Majid, A.Y. (author), van der Horst, C. (author), van Rietbergen, T.L. (author), Zwart, D.J. (author), Venkatesha Prasad, Ranga Rao (author)The ability to localize a sound source is essential for safe integration of robots in our society. However, its high computational demand makes it challenging to equip small swarm robots with such capability. Therefore, this paper investigates potential means for developing a lightweight sound source localization method. It introduces the...conference paper 2021

van der Horst, M.R.J. (author)Containerisation has led to increased competition between ports and put pressure on the use of scarce hinterland infrastructure. Having good coordination between all actors involved in port-related transport, including infrastructural access to the hinterland, is required to be successful in container port competition. In hinterland chains,...doctoral thesis 2016

van der Horst, J. (author)Optical imaging is one of the primary tools in biological and medical research. Over the years many different optical imaging modalities have been developed that have driven the imaging performance in terms of image resolution, contrast, imaging time, and maximum allowed sample size. The goal of this work is to develop techniques for 3D optical...doctoral thesis 2018

van der Horst, M.P. (author)Ship and offshore structures are prone to fatigue damage as they are cyclically<br/>loaded by waves. Therefore, regular inspection is needed in order to confirm adequate structural integrity throughout the entire service life of the structure. Detected fatigue cracks that are too long for safe operation need to be repaired. Detected cracks of...doctoral thesis 2018

van der Meer, Jeroen (author), Hartmann, Andreas (author), van der Horst, A.Q.C. (author), Dewulf, Geert (author)Awareness of design risks is essential for preparing integrated design and construction tenders as decisions in this phase can have serious consequences once the project is awarded. The practice of multi-criteria decision analysis (MCDA) promises to support contractors in dealing with risks in the decision-making process. However, due to...journal article 2022

The replication checkpoint protein Mrc1 plays important roles in these processes, although its functional interactions are not fully understood. Here, we show that MRC1 negatively interacts...journal article 2022

(author)Flight endurance is still a bottleneck for many types of unmanned air vehicle (UAV) applications. While battery technology improves over the years, for flights that last an entire day, batteries are still insufficient. Hydrogen-powered fuel cells offer an interesting alternative but pose stringent requirements on the platform. The required...journal article 2020

However, optical imaging deep in tissue is severely limited by light scattering, posing restrictions on the imaging depth, image contrast, and spatial resolution. We demonstrate optical coherence projection...journal article 2020

van der Horst, Koen (author), Diab, I. (author), Chandra Mouli, G.R. (author), Bauer, P. (author)The traction substations of urban electric transport grids are oversized and underutilized in terms of their capacity. While their over-sizing is an unfortunate waste, their under-utilization creates the major hurdle for the integration of renewables into these grids due to the lack of a base load. Therefore, integrating smart grid loads such...journal article 2023
