Coco Martin, C.M. (author), Hu, Weiya (author), Cavallo, D. (author)This work aims to provide guidelines on the design of wideband flat lenses based on artificial dielectric layers (ADLs). Planar lenses based on metasurfaces are typically narrowband, due to the phase wrapping over the period of 2\pi that is strongly frequency-dependent. On the contrary, true-time-delay (TTD) planar lenses, which do not resort...journal article 2024

Waaijer, Marijn (author), van Neerven, J.M.A.M. (author)In this article, we present a detailed analysis of two famous delayed choice experiments: Wheeler’s classic gedanken-experiment and the delayed quantum eraser. Our analysis shows that the outcomes of both experiments can be fully explained on the basis of the information collected during the experiments using textbook quantum mechanics only....journal article 2024

Kroep, H.J.C. (author), Gokhale, V. (author), Verburg, Joseph (author), Venkatesha Prasad, Ranga Rao (author)The next frontier in communications is teleoperation - manipulation and control of remote environments with haptic feedback. Compared to conventional networked applications, teleoperation poses widely different requirements, ultra-low latency (ULL) is primary. Realizing ULL communication demands significant redesign of conventional networking...journal article 2024

(author), De la Cruz, Adrian Flores (author), Gomez-Olive, Adria (author), Garcia-Mondejar, Albert (author), Aparici, Monica Roca i. (author)The 2-D frequency-based omega-K method is known to be a suitable algorithm for fully focused SAR (FF-SAR) radar altimeter processors, as its computational efficiency is much higher than equivalent time-based alternatives without much performance degradation. In this article, we provide a closed-form description of a 2-D frequency-domain omega...journal article 2024

Zhang, Lu (author), van Schie, M.S. (author), Xiang, Hongxian (author), Liao, Rongheng (author), Zheng, Jiahao (author), Knops, Paul (author), Taverne, Yannick J.H.J. (author), de Groot, N.M.S. (author)(1) Background: Structural remodeling plays an important role in the pathophysiology of atrial fibrillation (AF). It is likely that structural remodeling occurs transmurally, giving rise to electrical endo-epicardial asynchrony (EEA). Recent studies have suggested that areas of EEA may be suitable targets for ablation therapy of AF. We...journal article 2024

Binatari, N. (author), van Horssen, W.T. (author), Verstraten, P. (author), Adi-Kusumo, F. (author), Aryati, L. (author)In this paper, we present a new approach on how the multiple time-scales perturbation method can be applied to differential-delay equations such that approximations of the solutions can be obtained which are accurate on long time-scales. It will be shown how approximations can be constructed which branch off from solutions of differential...journal article 2024

Cortés, Carlos (author), Viola, Irene (author), Gutiérrez, Jesús (author), Jansen, Jack (author), Subramanyam, S. (author), Alexiou, Evangelos (author), Pérez, Pablo (author), García, Narciso (author), Cesar, Pablo (author)Immersive technologies like eXtended Reality (XR) are the next step in videoconferencing. In this context, understanding the effect of delay on communication is crucial. This article presents the first study on the impact of delay on collaborative tasks using a realistic Social XR system. Specifically, we design an experiment and evaluate the...journal article 2024

Ma, L. (author), Qiu, Z. (author), Van Mieghem, P.F.A. (author), Kitsak, M.A. (author)Epidemic forecasts are only as good as the accuracy of epidemic measurements. Is epidemic data, particularly COVID-19 epidemic data, clean, and devoid of noise? The complexity and variability inherent in data collection and reporting suggest otherwise. While we cannot evaluate the integrity of the COVID-19 epidemic data in a holistic fashion, we...journal article 2024

Beltman, Maarten (author)Punctuality is a key performance indicator for any airline. Hub-and-spoke airlines are particularly committed to on-time arrivals to guarantee passenger connections. Flights that are delayed at departure need to compensate for the lost time whilst airborne. Because fueling takes place well before scheduled departure, predicted departure delays...master thesis 2023

Erblich, Hans (author)In this thesis, the functioning of passenger delay-based refund schemes in urban public transportation settings is evaluated, such as metros or light-rails. These are used when a passenger encounters a delay on their trip, in order to grant a form of refund to them. To the best of knowledge, no research has been carried out yet on several...master thesis 2023

Post, Jan (author)As aviation recovers to pre-pandemic levels large amounts of Air Traffic Flow Management delay also return, as the traffic at airports and in airspaces reaches their old levels. These delays have a yearly cost of around 500 million euros in the European Civil Aviation Conference area and are detrimental to the experience of passengers. This...master thesis 2023

Ethuin, Guillaume (author)Capacity and performance (evaluated through delay propagation) analysis methods have mostly focused on railway line track sections, but less attention has been given to nodes. Still, a few analytical methods for the capacity and performance assessment of the switch areas between station platform tracks and line tracks can be classified upon...master thesis 2023

Zhang, Zhengquan (author)Trust plays an important role in the implementation of chatbot technology. This study was also focusing on user trust in chatbots, particularly focusing on the role of response delay and explanation-driven driven subjective transparency. This research includes a pretest and a main test. In the pretest, we selected one explanation that was...master thesis 2023

Lammers, Laurens (author)Neuromorphic sensors, like for example event cameras, detect incremental changes in the sensed quantity and communicate these via a stream of events. Desired properties of these signals such as high temporal resolution and asynchrony are not always fully exploited by algorithms that process these signals. Spiking neural networks (SNNs) have...master thesis 2023

Li, Wenkai (author)Concurrency bugs are easy to introduce but dif- ficult to detect, especially in implementations of distributed algorithms where concurrency non- determinism is an inherent problem. These bugs may only be identified under very specific order- ings of execution events, making them challenging to reproduce. Controlled concurrency testing tech-...bachelor thesis 2023

Rasman, Brandon G. (author), van der Zalm, P.C. (author), Forbes, P.A. (author)Background: While standing upright, the brain must accurately accommodate for delays between sensory feedback and self-generated motor commands. Natural aging may limit adaptation to sensorimotor delays due to age-related decline in sensory acuity, neuromuscular capacity and cognitive function. This study examined balance learning in young and...journal article 2023

de Ruijter, A.J.F. (author), Cats, O. (author), Alonso-Mora, J. (author), Hoogendoorn, S.P. (author)Previous studies into the potential benefits of ride pooling failed to account for the trade-off that users likely make when considering a shared ride. We address this shortcoming by formulating user net benefit stemming from pooling as a compensatory function where the additional travel time and on-board discomfort need to be compensated by...journal article 2023
