Verhagen, J. (author), Xiong, Xiaobin (author), Ames, A. D. (author), Seth, A. (author)Humans are able to negotiate downstep behaviors-both planned and unplanned-with remarkable agility and ease. The goal of this paper is to systematically study the translation of this human behavior to bipedal walking robots, even if the morphology is inherently different. Concretely, we begin with human data wherein planned and unplanned...conference paper 2022

Barczyk, R.T. (author), Parappurath, N. (author), Arora, S. (author), Bauer, T.A. (author), Kuipers, L. (author), Verhagen, E. (author)We study the signatures of topological light confinement in the leakage radiation of two-dimensional topological photonic crystal cavities that feature the quantum spin Hall effect at telecom wavelengths. The mode profiles in real and momentum space are retrieved using far field imaging and Fourier spectropolarimetry. We examine the scaling...conference paper 2022

Kaandorp, C. (author), Miedema, T. (author), Verhagen, J.D. (author), van de Giesen, N.C. (author), Abraham, E. (author)Infrastructure for heat provision in the built environment needs to change remarkably to support lowering carbon emissions and achieving climate mitigation targets before 2050. We propose a computational approach for finding a mix of heat options per neighbourhood that minimises cumulative carbon emissions between 2030 and 2050, referred to as...journal article 2022

(author)Distributing quantum entanglement on a chip is a crucial step toward realizing scalable quantum processors. Using traveling phonons-quantized guided mechanical wave packets-as a medium to transmit quantum states is now gaining substantial attention due to their small size and low propagation speed compared to other carriers, such as electrons...journal article 2022

Bieber, M.T. (author), Verhagen, W.J.C. (author), Santos, Bruno F. (author)Metrics play an important part in the development and application of prognostic methodologies as they provide the capability to characterize and assess the quality of remaining useful life predictions. Although there is a wide range of both, prognostic metrics and prognostic methodologies available, the choice of those often is a demanding and...conference paper 2022

Mirmohammadian, Farinaz (author), Asgari, Jamal (author), Verhagen, S. (author), Amiri Simkooei, A. (author)With the advancement of multi-constellation and multi-frequency global navigation satellite systems (GNSSs), more observations are available for high precision positioning applications. Although there is a lot of progress in the GNSS world, achieving realistic precision of the solution (neither too optimistic nor too pessimistic) is still an...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

Scott, Michael J. (author), Verhagen, W.J.C. (author), Bieber, M.T. (author), Marzocca, Pier (author)In recent decades, the increased use of sensor technologies, as well as the increase in digitalisation of aircraft sustainment and operations, have enabled capabilities to detect, diagnose, and predict the health of aircraft structures, systems, and components. Predictive maintenance and closely related concepts, such as prognostics and health...journal article 2022

Newcamp, Jeffrey M. (author), Verhagen, W.J.C. (author), Curran, R. (author)Aircraft fleet managers lack tools to aid decision-making for fleets nearing retirement, which leads to rushed and ill-informed decisions. Accordingly, aging aircraft fleets are underutilized and fleets can be retired before their useful lifetime has been expended. A decision support framework is proposed to solve the aging military aircraft...conference paper 2022

Verhagen, Teun Johannes (author), Cetinay, Hale Iyicil (author), Van Der Voet, Ester (author), Sprecher, Benjamin (author)To achieve climate neutrality, future urban heating systems will need to use a variety of low-carbon heating technologies. The transition toward low-carbon heating technologies necessitates a complete restructuring of the heating system, with significant associated material requirements. However, little research has been done into the...journal article 2022

Mirmohammadian, Farinaz (author), Asgari, Jamal (author), Verhagen, S. (author), Amiri Simkooei, A. (author)Until now, RTK (real-time kinematic) and NRTK (Network-based RTK) have been the most popular cm-level accurate positioning approaches based on Global Navigation Satellite System (GNSS) signals in real-time. The tropospheric delay is a major source of RTK errors, especially for medium and long baselines. This source of error is difficult to...journal article 2022

Verhagen, R.S. (author), Neerincx, M.A. (author), Tielman, M.L. (author)Humans and robots are increasingly working together in human-robot teams. Teamwork requires communication, especially when interdependence between team members is high. In previous work, we identified a conceptual difference between sharing what you are doing (i.e., being transparent) and why you are doing it (i.e., being explainable). Although...journal article 2022

Bieber, M.T. (author), Verhagen, W.J.C. (author)In recent years, there has been an enormous increase in the amount of research in the field of prognostics and predictive maintenance for mechanical and electrical systems. Most of the existing approaches are tailored to one specific system. They do not provide a high degree of flexibility and often cannot be adaptively used on different systems...journal article 2022

Deng, Q. (author), Santos, Bruno F. (author), Verhagen, W.J.C. (author)Modern aircraft have thousands of parts, systems, and components that need to be recurrently inspected or replaced. To keep the fleet airworthy, maintenance planners have to schedule the maintenance checks for each aircraft and the associated tasks. In practice, these two complex problems are solved following the experience of planners,...journal article 2021

Implementing Business Models Into Operations: Impact of Business Model Implementation on PerformanceVerhagen, M.P. (author), de Reuver, Mark (author), Bouwman, W.A.G.A. (author)Business models (BMs) help firms to translate abstract strategic decisions into their daily operations. Because BMs mediate between strategy and operations, BM innovation involves both high-level strategic experiments and low-level implementation into operations and technologies. However, most existing empirical studies regarding BM innovation...journal article 2021

Ma, H. (author), Psychas, D.V. (author), Xing, Xuhuang (author), Zhao, Qile (author), Verhagen, S. (author), Liu, Xianglin (author)The tropospheric delay is one of many error sources that affect the Global Navigation Satellite System (GNSS) positioning solutions. The widely used troposphere models assume a homogeneous atmosphere so that only the zenith delay needs to be determined and is mapped through an elevation-dependent mapping function. This procedure is to reduce...journal article 2021
