Clarke, Nicholas (author), Kuipers, M.C. (author)This paper continues on from a recently completed research project on shared built heritage of South Africa and the Netherlands from 1902–61, mainly created by Dutch–born architects. It focuses on two pioneering female architects in South Africa, Gertruida Brinkman (1906–77, née Siemerink) and Eleanor Ferguson (also Stakesby–Lewis; 1900–82),...conference paper 2022

Kuipers, M.C. (author)Een vraag vanuit Zuid-Afrika leidde tot de ontdekking van ir. J.E. Ferguson (1900-1982) en haar bijzondere loopbaan. Zij was een van de eerste professionele architectes in Nederland, maar haar werk is vrijwel onbekend. Samen met haar derde echtgenoot had zij een eigen bureau in achtereenvolgens Johannesburg en Salisbury (nu Harare). In 1961...journal article 2022

Kuipers, T. (author), Su, Renbo (author), Wu, J. (author), Wang, Charlie C.L. (author)Material Extrusion (MEX) systems with dual-material capability can unlock interesting applications where flexible and rigid materials are combined. When chemically incompatible materials are concerned the adhesion between the two might be insufficient. Therefore researchers typically rely on dovetail type interlocking geometries in order to...journal article 2022

Arora, S. (author), Bauer, T.A. (author), Parappurath, N. (author), Barczyk, R.T. (author), Verhagen, E. (author), Kuipers, L. (author)We measure the local near-field spin in topological edge state waveguides that emulate the quantum spin Hall effect. We reveal a highly structured spin density distribution that is not linked to a unique pseudospin value. From experimental near-field real-space maps and numerical calculations, we confirm that this local structure is essential...journal article 2022

(author), Alù, Andrea (author), Kuipers, L. (author)Near-field scanning optical microscopy is a powerful technique for imaging below the diffraction limit, which has been extensively used in biomedical imaging and nanophotonics. However, when the electromagnetic fields under measurement are strongly confined, they can be heavily perturbed by the presence of the near-field probe itself. Here,...journal article 2022

Polachan, Kurian (author), Pal, Joydeep (author), Singh, Chandramani (author), Prabhakar, T. V. (author), Kuipers, F.A. (author)Tactile Internet based Cyber-Physical Systems (TCPS) are highly sensitive to component and communication la- tencies and packet drops. Building a high performing TCPS, thus, necessitates experimenting with different hardware, algorithms, access technologies, and communication protocols. To facilitate such experiments, we have developed TCPSbed,...journal article 2022

He, Nan (author), Yang, S. (author), Li, Fan (author), Trajanovski, S. (author), Kuipers, F.A. (author), Fu, Xiaoming (author)The efficacy of Network Function Virtualization (NFV) depends critically on (1) where the virtual network functions (VNFs) are placed and (2) how the traffic is routed. Unfortunately, these aspects are not easily optimized, especially under time-varying network states with different quality of service (QoS) requirements. Given the importance of...conference paper 2021

Hernandez Rueda, F.J. (author), Noordam, M.L. (author), Komen, I. (author), Kuipers, L. (author)Currently, the nonlinear optical properties of 2D materials are attracting the attention of an ever-increasing number of research groups due to their large potential for applications in a broad range of scientific disciplines. Here, we investigate the interplay between nonlinear photoluminescence (PL) and several degenerate and nondegenerate...journal article 2021

(author), Xu, Guixian (author), Lukkien, Johan (author), Chen, Shanzhi (author)Software-defined networking (SDN) is a cornerstone of next-generation networks and has already led to numerous advantages for data-center networks and wide-area networks. However, SDN is not widely adopted in constrained networks, such as Wireless Sensor Networks (WSN), due to excessive control overhead, lossy medium, and in-band control...journal article 2021

Maduro, L.A. (author), Noordam, M.L. (author), Bolhuis, M. (author), Kuipers, L. (author), Conesa Boj, S. (author)The fabrication of 2D materials, such as transition metal dichalcogenides (TMDs), in geometries beyond the standard platelet-like configuration exhibits significant challenges which severely limit the range of available morphologies. These challenges arise due to the anisotropic character of their bonding van der Waals out-of-plane while...journal article 2021

Turkovic, B. (author), Nijhuis, S.H. (author), Kuipers, F.A. (author)The concept of network slicing enables operators to provision multiple virtual networks on top of a single (shared) physical infrastructure. Adding elasticity to slicing, i.e., the ability to on-demand provision/release dedicated network resources, improves resource utilization.

Oostenbrink, J. (author), Kuipers, F.A. (author)Network outages have significant economic and societal costs. While network operators have become adept at managing smaller failures, this is not the case for larger, regional failures such as natural disasters. Although it is not possible, and certainly not economic, to prevent all potential disaster damage and impact, we can reduce their...conference paper 2021

Doing so by deploying flow-specific rules at network nodes would require significant memory and overhead.<br/>In this paper, we take a fundamentally different approach, called P4QoS, by embedding QoS requirements in the packets...conference paper 2021
