Clarke, Nicholas (author), Kuipers, M.C. (author), Stroux, S.A. (author)Continuity and change have become crucial themes for the built environment and heritage buildings; also in the education and practice of architects. 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

Valentini, Alessandro (author), Vass, Balazs (author), Oostenbrink, J. (author), Csak, Levente (author), Kuipers, F.A. (author), Pace, Bruno (author), Hay, David (author), Tapolcai, Janos (author)Guaranteeing a high availability of network services is a crucial part of network management. In this study, we show how to compute the availability of network services under earthquakes, by using empirical data. We take a multi-disciplinary approach and create an earthquake model based on seismological research and historical data. We then show...conference paper 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

Finotello, Giulia (author), Padding, J.T. (author), Buist, Kay A. (author), Schijve, Annelien (author), Jongsma, Alfred (author), Innings, Fredrik (author), Kuipers, J.A.M. (author)Large scale simulation models can aid in improving the design of spray dryers. In this work an Eulerian-Lagrangian model with coupled gas phase and droplet heat and mass transfer balances is used to study airflow dynamics, temperature and humidity profiles at different positions in the spray. The turbulent gas flow is solved using large eddy...journal article 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

le Feber, B. (author), Sipe, J. E. (author), Wulf, M. (author), Kuipers, L. (author), Rotenberg, N. (author)Light is a union of electric and magnetic fields, and nowhere is the complex relationship between these fields more evident than in the near fields of nanophotonic structures. There, complicated electric and magnetic fields varying over subwavelength scales are generally present, which results in photonic phenomena such as extraordinary...journal article 2019

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

(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

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

Turkovic, B. (author), Kuipers, F.A. (author), van Adrichem, Niels (author), Langendoen, K.G. (author)Along with exciting visions for 5G communications and the Tactile Internet, the networking requirement of attaining extremely low end-to-end latency has appeared. While network devices are typically equipped with buffers to counteract packet loss caused by short-lived traffic bursts, the more those buffers get filled, the more delay is added to...conference paper 2018

Yang, Xueying (author), Karampatzakis, Evgenios (author), Dörr, C. (author), Kuipers, F.A. (author)LoRaWAN is a MAC-layer protocol for long-range low-power communication. Since its release in 2015, it has experienced a rapid adoption in the field of Internet-of-Things (IoT). However, given that LoRaWAN is fairly novel, its level of security has not been thoroughly analyzed, which is the main objective of this paper. We highlight the security...conference paper 2018

Kuipers, Rutger (author)New methods for aircraft movables introduce oblique- and out-of-plane loads on lug joints. With the introduction of these loads on lugs the need arises for a more detailed fatigue life prediction method. <br/><br/>Therefore, the thesis research focused on creating a methodology for predicting the fatigue life for lug joints subjected to combined...master thesis 2018

(author)Designing an optimal network topology while balancing multiple, possibly conflicting objectives like cost, performance, and resiliency to viruses is a challenging endeavor, let alone in the case of decentralized network formation. We therefore propose a game-formation technique where each player aims to minimize its cost in installing links,...journal article 2018

(author)In this paper, we compare the effects of failures in power grids under the nonlinear AC and linearized DC power flow models. First, we numerically demonstrate that when there are no failures and the assumptions underlying the DC model are valid, the DC model approximates the AC model well in four considered test networks. Then, to evaluate...journal article 2018

Mahajan, V.V. (author), Padding, J.T. (author), Nijssen, Tim M.J. (author), Buist, Kay A. (author), Kuipers, J.R. (author)Fluidization is widely used in industries and has been extensively studied, both experimentally and theoretically, in the past. However, most of these studies focus on spherical particles while in practice granules are rarely spherical. Particle shape can have a significant effect on fluidization characteristics. It is therefore important to...journal article 2018

(author)This work presents a halftoning technique to manufacture 3D objects with the appearance of continuous grayscale imagery for Fused Deposition Modeling (FDM) printers. While droplet-based dithering is a common halftoning technique, this is not applicable to FDM printing, since FDM builds up objects by extruding material in semi-continuous paths....journal article 2018

Kamath, S. (author), Padding, J.T. (author), Buist, K. A. (author), Kuipers, J.R. (author)A stochastic Direct Simulation Monte Carlo (DSMC) method has been extended for handling bubble-bubble and bubble-wall collisions. Bubbly flows are generally characterized by highly correlated velocities due to presence of the surrounding liquid. The DSMC method has been improved to account for these kind of correlated collisions along with a...journal article 2018
