van Duin, Ron (author), Vlot, T.S. (author), Tavasszy, Lorant (author), Duinkerken, M.B. (author), van Dijk, Bernd (author)Parcel delivery operators experience an increasing pressure to meet the strongly growing demand for delivery services, while protecting city livability and the environment. Improving the performance of the last mile of delivery is considered key in meeting this challenge as it forms the most inefficient, expensive, and environmentally unfriendly...journal article 2020

van Dijk, J.P.G. (author), Patra, B (author), Pellerano, Stefano (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author), Babaie, M. (author)The design of a large-scale quantum computer requires co-optimization of both the quantum bits (qubits) and their control electronics. This work presents the first systematic design of such a controller to simultaneously and accurately manipulate the states of multiple spin qubits or transmons. By employing both analytical and simulation...journal article 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)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

Kaltekis, K. (author), Panagoulias, S. (author), van Dijk, B.F.J. (author), Brinkgreve, R.B.J. (author), Ramos da Silva, M. (author)Offshore wind turbine generators (WTG) are commonly founded on single large diameter piles, named monopiles. These monopiles are subjected to significant lateral loads and thereby sizeable overturning bending moments mainly due to action of wind and wave forces; thus the critical geotechnical design situation for monopiles supporting WTGs is...journal article 2019

van Dijk, J.P.G. (author), Charbon-Iwasaki-Charbon, E. (author), Sebastiano, F. (author)Quantum computers can potentially provide an unprecedented speed-up with respect to traditional computers. However, a significant increase in the number of quantum bits (qubits) and their performance is required to demonstrate such quantum supremacy. While scaling up the underlying quantum processor is extremely challenging, building the...journal article 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
