Yu, D. (author), Arora, S. (author), Kuipers, L. (author)We investigate how altering the interface geometry from a zigzag to a glide plane interface between two topologically distinct valley Hall emulating photonic crystals (VPC), profoundly affects edge states. We experimentally observe a transition from gapless to gapped edge states, accompanied by the occurrence of slow light within the...journal article 2024

Bhattacharjee, A.K. (author), Cecconello, S. (author), Kuipers, F.A. (author), Smaragdakis, G. (author)To avoid exploitation of known vulnerabilities, it is standard security practice to not disclose any model information regarding the antennas used in cellular infrastructure. However, in this work, we show that end-user devices receive enough information to infer, with high accuracy, the model-family of antennas. We demonstrate how low-cost...conference paper 2024

Clarke, Nicholas (author), Kuipers, M.C. (author)Addressing the complex legacies of the past in architectural education and built constructions, calls for a reconsidering of the principles of architectural design and conservation. The current challenges of housing, sustainable development and heritage adaptation present huge dilemmas for architects. Yet today architects are only by exception...journal article 2023

(author)With the emergence of remote education and work in universi- ties due to COVID-19, the ‘zoomification’ of higher education, i.e., the migration of universities to the clouds, reached the public dis- course. Ongoing discussions reason about how this shift will take control over students’ data away from universities, and may ulti- mately harm the...book chapter 2023

Kuipers, M.C. (author), Clarke, Nicholas (author)Pieter Simon Dijkstra (1884-1968) is regarded as a noted Protestant church designer in South Africa, but his contribution to the built environment in the Netherlands is much less well known. His life and career in the country of his birth are of interest because they are closely aligned with the religious turbulence of the period, in which the...journal article 2023

Zapletal, A. (author), Kuipers, F.A. (author)The conventional definition of fairness in congestion control is flow rate fairness. However, Internet users typically care about flow completion times (FCTs) and flow rate fairness does not lead to equitable FCTs for different users. Therefore, we reconsider what it means for congestion control to be fair and posit a novel stance on fairness:...conference paper 2023

Kuipers, J.R. (author), de Winter, J.C.F. (author), Mulder, Max (author)Background: Even though accompanied driving and simulator training are common, clarity on their usage trends and effectiveness is lacking. This research aimed to deepen the understanding of the relationships between personal characteristics, pre-licence accompanied driving, self-reported post-licence driving behaviour, and driving performance...journal article 2023

(author), Kuipers, L. (author), Giessen, Harald (author)The creation and manipulation of optical vortices, both in free space and in two-dimensional systems such as surface plasmon polaritons (SPPs), has attracted widespread attention in nano-optics due to their robust topological structure. Coupled with strong spatial confinement in the case of SPPs, these plasmonic vortices and their underlying...journal article 2023

Hernandez-Rueda, Javier (author), Pérez-Benito, Óscar (author), Martínez Maestro, Laura (author), Noordam, M.L. (author), Kuipers, L. (author), Weigand, Rosa (author)Nowadays, the accurate and full temporal characterization of ultrabroadband few-cycle laser pulses with pulse durations below 7 fs is of great importance in fields of science that investigate ultrafast dynamic processes. There are several indirect methods that use nonlinear optical signals to retrieve the complex electric field of femtosecond...journal article 2023

Kuipers, Jeroen (author), Schoenmakers, Gijs (author), Staňková, K. (author)We consider two-player zero-sum differential games of fixed duration, where the running payoff and the dynamics are both linear in the controls of the players. Such games have a value, which is determined by the unique viscosity solution of a Hamilton–Jacobi-type partial differential equation. Approximation schemes for computing the viscosity...journal article 2023

Ji, C. (author), Kuipers, F.A. (author)To cater to constantly changing network needs, enabling stateful reconfiguration of Network Functions (NFs) is crucial. Recently, there has been growing interest in offloading NFs to programmable network devices. Unfortunately, it is currently not possible to maintain the full state of NFs during a switch reconfiguration without consuming...conference paper 2023

With the rapidly growing personalized demand for real-time video streaming services, maximizing their Quality of Experience (QoE) is a long-standing challenge. The emergence of the server- less computing paradigm has potential to...conference paper 2023

Kuipers, T. (author)The products in our day to day lives have different requirements in different regions of the product. One way of dealing with such spatially varying requirements is to divide the product into multiple parts and assign each part a different material. For example, the handle of a drill is often fitted with a rubbery material which gives it more...doctoral thesis 2022

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

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

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
