de Smale, S. (author), van Dijk, Rik (author), Bouwman, X.B. (author), van der Ham, Jeroen (author), van Eeten, M.J.G. (author)The number of published software vulnerabilities is increasing every year. How do organizations stay in control of their attack surface despite their limited staff resources? Prior work has analyzed the overall software vulnerability ecosystem as well as patching processes within organizations, but not how these two are connected. We investigate...conference paper 2023

Meester, R.S. (author), van Dijk, Tom (author), de Wagter, C. (author), de Croon, G.C.H.E. (author)Obstacle avoidance is an important capability for flying robots. But for robots with limited resources, such as small drones this becomes particularly challenging. Bug algorithms have been proposed to solve path planning with only minimal resources. And stereo vision provides a rich description of the world for limited weight but typically has a...conference paper 2023

Hoogelander, M. (author), van Dijk, R. (author), Alonso Del Pino, M. (author), Spirito, M. (author), Llombart, Nuria (author)The design of a focal plane array (FPA) for imaging at sub-mm wavelengths generally is a trade-off between resolution and sensitivity. For maximum angular resolution, minimal spacing between FPA elements is desired, which leads to increased losses due to spillover and mutual coupling and therefore deteriorates the imaging sensitivity. This work...conference paper 2023

Bascunan, S. (author), Kaltekis, K. (author), van Dijk, B. (author), Gavin, Kenneth (author)A joint academia-industry project, the Pile Soil Analysis (PISA) project, resulted in an empirical method for assessing the monotonic lateral loading response of large diameter monopiles. The method predicts four soil reactions, namely the distributed load and the distributed moment along the pile shaft, the pile base shear and the pile base...conference paper 2022

Chen, Hao (author), Van Rijnsoever, Ben (author), Molenhuis, Marcel (author), van Dijk, Dennis (author), Tan, Y. (author), Rukanova, B.D. (author)As an increasing volume of international trade activities around the world, the amount of cross-boarder import declarations grows rapidly, resulting in an unprecedented scale of potentially fraudulent transactions, in particular false commodity code (e.g., HS Code). The incorrect HS Code will cause duty risk and adversely impact the revenue...conference paper 2021

(author)Cryogenic CMOS (cryo-CMOS) is a viable technology for the control interface of the large-scale quantum computers able to address non-trivial problems. In this paper, we demonstrate state-of-the-art cryo-CMOS circuits and systems for such application and we discuss the challenges still to be faced on the path towards practical quantum...conference paper 2020

(author), Vandersypen, L.M.K. (author), Babaie, M. (author), Sebastiano, F. (author), Charbon-Iwasaki-Charbon, E. (author)Quantum computers (QC), comprising qubits and a classical controller, can provide exponential speed-up in solving certain problems. Among solid-state qubits, transmons and spin-qubits are the most promising, operating « 1K. A qubit can be implemented in a physical system with two distinct energy levels representing the |0) and |1) states, e.g...conference paper 2020

van Dijk, Tom (author), de Croon, G.C.H.E. (author)Deep neural networks have lead to a breakthrough in depth estimation from single images. Recent work shows that the quality of these estimations is rapidly increasing. It is clear that neural networks can see depth in single images. However, to the best of our knowledge, no work currently exists that analyzes what these networks have learned. In...conference paper 2019

(author)Pumped irrigation is a way to improve water control for smallholder farming, hence to intensify its production. In this context, the Dutch company aQysta has developed the Barsha pump (BP), the first-ever commercial version of a hydro-powered pump traditionally referred to as spiral pump. BPs, however, have to deal with several constraints that...conference paper 2019

(author)To investigate how an Unmanned Air Vehicle (UAV) can detect manned aircraft with a single microphone, an audio data set is created in which UAV ego-sound and recorded aircraft sound are mixed together. A convolutional neural network is used to perform the air traffic detection. Due to restrictions on flying UAVs close to aircraft, the data set...conference paper 2019

Olejnik, D.A. (author), Karasek, M. (author), Duisterhof, Bart (author), Scheper, K.Y.W. (author), van Dijk, Tom (author), de Croon, G.C.H.E. (author)In the field of robotics, a major challenge is achieving high levels of autonomy with small vehicles that have limited mass and power budgets. The main motivation for designing such small vehicles is that, compared to their larger counterparts, they have the potential to be safer, and hence be available and work together in large numbers. One of...conference paper 2019

Cisneros, Julia (author), Best, Jim (author), van Dijk, Thaiënne A G P (author), Mosselman, E. (author)In natural rivers, flow discharge may fluctuate across a range of time scales – from diurnal to seasonal - but is often most pronounced during hydrographs that may encompass long-duration floods. Under these varying flows, bedforms can be created and modified by the flow without achieving any ‘equilibrium’ state. A lag between changes in flow...conference paper 2019

Gangoli Rao, A. (author), Sharma, A. (author), van Dijk, R.E.C. (author)The Advisory Council for Aeronautics Research in Europe (ACARE) has set an ambitious array of objectives to be accomplished by 2050 for civil aviation. It is often claimed that complying with those targets will not require evolution but, rather, revolution. If the growth in aviation has to be sustained in the future, then we must come up with...conference paper 2017

van Dijk, M.T. (author), van Wingerden, J.W. (author), Ashuri, T. (author), Li, Y. (author), Rotea, M.A. (author)To make wind energy cost competitive with traditional resources, wind turbines are commonly placed in groups. Aerodynamic interaction between the turbines causes sub-optimal energy production. A control strategy to mitigate these losses is by redirecting the wake by yaw misalignment. This paper aims to assess the influence of load variations of...conference paper 2016

(author), Rodriguez Aguilera, D. (author), Menninga, P.J. (author), Noorlandt, R.P. (author)Sedimentary coasts and shallow-sea beds may be dynamic. The large-scaled spatial variation in these dynamics and the smaller-scaled behaviour of individual marine bedforms are largely unknown. Sea-bed dynamics are relevant for the safety of shipping, and therefore for monitoring strategies, and for offshore engineering projects and...conference paper 2012
