Oostenbrink, J. (author), Kuipers, F.A. (author), Helvik, Bjarne E. (author), Heegaard, Poul E. (author)It is of vital importance to maintain at least some network functionality after a disaster, for example by temporarily replacing damaged nodes by emergency nodes. We propose a framework to evaluate dierent node replacement strategies, based on a large set of representative disasters. We prove that computing the optimal choice of nodes to...journal article 2019

Çetinay Iyicil, H. (author), Koc, Y. (author), Kuipers, F.A. (author), Van Mieghem, P.F.A. (author)Direct connections between nodes usually result in efficient transmission in networks. Such electric power transmission is governed by physical laws, and an assessment purely based on direct connections between nodes and shortest paths may not capture the operation of power grids. Motivated by these facts, in this chapter, we investigate the...book chapter 2019

Alpeggiani, F. (author), Kuipers, L. (author)Bichromatic photonic crystal structures are based on the coexistence of two different periodicities in the dielectric constant profile. They are realized starting from a photonic crystal waveguide and modifying the lattice constant only in the waveguide region. In this work, we numerically investigate the spectral and topological properties...journal article 2019

de Angelis, L. (author), Bauer, T.A. (author), Alpeggiani, F. (author), Kuipers, L. (author)When the positions of two generic singularities of equally signed topological index coincide, a higher-order singularity with twice the index is created. In general, singularities tend to repel each other when sharing the same topological index, preventing the creation of such higher-order singularities in 3D generic electromagnetic fields....journal article 2019

(author), Kuipers, L. (author), Orrit, Michel (author)Circular dichroism (CD) spectroscopy is a powerful optical technique for the study of chiral materials and molecules. It gives access to an enantioselective signal based on the differential absorption of right and left circularly polarized light, usually obtained through polarization analysis of the light transmitted through a sample of...journal article 2019

Sengar, A. (author), Kuipers, J. A.M. (author), van Santen, R. A. (author), Padding, J.T. (author)Particle based approaches are one of the recent modeling techniques to overcome the computational limitation in multiscale modeling of complex processes, for example a heterogeneous catalytic reactor. We propose an efficient model for a chemical reactor where hydrodynamics of the solvent is determined by Stochastic Rotation Dynamics and a...journal article 2019

Finotello, Giulia (author), Padding, J.T. (author), Buist, Kay A. (author), Jongsma, Alfred (author), Innings, Fredrik (author), Kuipers, J. A.M. (author)In this work we investigate droplet-droplet collision interactions in a spray system using an Eulerian-Lagrangian model with subgrid turbulence dispersion. The effect of different droplet viscosities on the type and frequency of droplet collision is investigated, knowledge of which is essential for industrial processes such as spray drying...journal article 2019

(author)In this work, we investigate the influence of channel structure and fluid rheology on non-inertial migration of non-Brownian polystyrene beads. Particle migration in this regime can be found in biomedical, chemical, environmental and geological applications. However, the effect of fluid rheology on particle migration in porous media remains...journal article 2019

Demetri, Silvia (author), Zuniga, Marco (author), Picco, Gian Pietro (author), Kuipers, F.A. (author), Bruzzone, Lorenzo (author), Telkamp, Thomas (author)Many research and industrial communities are betting on LoRa to provide reliable, long-range communication for the Internet of Things. This new radio technology, however, provides widely heterogeneous coverage; a LoRa link may span hundreds of meters or tens of kilometers, depending on the surrounding environment. This high variability is not...conference paper 2019

Kuipers, Derek A. (author), Terlouw, Gijs (author), Wartena, B.O. (author), Prins, Jelle T. (author), Pierie, Jean Pierrre E.N. (author)High fidelity is regarded as a hallmark of educational games and simulations for health education. Mainly physical and functional fidelity are associated with authenticity, resulting in the pursuit of a true-to-life simulation and suggesting the imposition of a generally accepted and often unintentional design rationale that assumes that the...journal article 2019

Kuipers, T. (author), Wu, J. (author), Wang, C.C. (author)The fabrication flexibility of 3D printing has sparked a lot of interest in designing structures with spatially graded material properties. In this paper, we propose a new type of density graded structure that is particularly designed for 3D printing systems based on filament extrusion. In order to ensure high-quality fabrication results,...journal article 2019

Embedding built heritage values into studio-based design education is a daunting new challenge that demands new didactic perspectives and tools. To address the dilemmas that come with design...journal article 2019

Cerqueira Afonso Alves, Renan (author), Borges Margi, Cintia (author), Kuipers, F.A. (author)The Internet of Things (IoT) has and will continue to permeate many aspects of everyday life. However, IoT de- vices often use wireless communication to transfer their data, which may experience ambient noise and multipath fading. This, together with the wide heterogeneity in types of devices, leads to the emergence of unidirectional links in...conference paper 2019

Oostenbrink, J. (author), Kuipers, F.A. (author)It is often assumed that a network will not be struck by multiple disasters in a relatively short period of time; that is, a subsequent disaster will not strike within the recovery phase of a previous disaster. However, recent events have shown that combinations of disasters are not implausible. This realization calls for a new perspective on...conference paper 2019

Mohammad Riftadi, M. (author), Kuipers, F.A. (author)Switches that can be (re)programmed through the network programming language P4 are able to completely change – even while in the field – the way they process packets. While powerful, P4 code is inherently static, as it is written and installed to accommodate a particular network requirement. Writing new P4 code each time new requirements arise...conference paper 2019
