(author), Matthes, Sigrun (author), Baspinar, Baris (author), Noorafza, M. (author), Roling, P.C. (author)Aviation significantly contributes to anthropogenic radiative forcing with both CO (Formula presented.) and non-CO (Formula presented.) emissions. In contrast to technical advancements to mitigate the climate impact, operational measures can benefit from short implementation times and thus are expected to be of high relevance in the near...journal article 2023

Du, Yunlu (author), Huang, Yunkai (author), Guo, Baocheng (author), Peng, Fei (author), Yao, Y. (author), Dong, J. (author)This article proposes a hybrid analytical model (HAM) for predicting ac copper losses in hairpin windings. The HAM combines the nonlinear semi-analytical model (SAM) and the 1-D ac copper loss computation model to solve the inaccurate boundary solutions of the 1-D ac copper loss computation model when magnetic saturation occurs in the stator...journal article 2023

van der Meulen, P.Q. (author), Coutino, Mario (author), Bosch, Johannes G. (author), Kruizinga, P. (author), Leus, G.J.T. (author)We consider the scenario of finding the transfer function of an aberrating layer in front of a receiving ultrasound (US) array, assuming a separate non-aberrated transmit source. We propose a method for blindly estimating this transfer function without exact knowledge of the ultrasound sources or acoustic contrast image, and without directly...journal article 2023

Ber, Aleksei F. (author), Borst, M.J. (author), Borst, Sander J. (author), Sukochev, F. (author)We prove that, for a finite-dimensional real normed space V, every bounded mean zero function f ∈ L<sub>∞</sub>([0, 1]; V) can be written in the form f = g ◦ T − g for some g ∈ L<sub>∞</sub>([0, 1]; V) and some ergodic invertible measure preserving transformation T of [0, 1]. Our method moreover allows us to choose g, for any given ε > 0,...journal article 2023

Mulder, G. (author), van Leijen, F.J. (author), Hanssen, R.F. (author)The observed phase in time series of interferometric synthetic aperture radar (InSAR) products is a superposition of various components. Differential topography, line-of-sight displacements, and differential atmospheric delays are the main contributions and need to be disentangled to derive accurate digital elevation model (DEM), deformation,...journal article 2023

Hille, Sander C. (author), Theewis, E.S. (author)Explicit expressions and computational approaches are given for the Fortet–Mourier distance between a positively weighted sum of Dirac measures on a metric space and a positive finite Borel measure. Explicit expressions are given for the distance to a single Dirac measure. For the case of a sum of several Dirac measures one needs to resort to...journal article 2023

(author)Surrogate Safety Measures (SSMs) are used to express road safety in terms of the safety risk in traffic conflicts. Typically, SSMs rely on assumptions regarding the future evolution of traffic participant trajectories to generate a measure of risk, restricting their applicability to scenarios where these assumptions are valid. In response to...journal article 2023

Pothof, I.W.M. (author), Vreeken, D. (author), van Meerkerk, M. (author)The energy required for space heating amounts to approximately 68% of the total energy demand of existing buildings in Europe. The heat requirement of a building, and thus its carbon emission, can be lowered by optimizing the supply and return temperature of the heating system. A lower supply temperature enables a wider variety of transition...journal article 2023

Ozcan, Selim (author), Livadariu, Ioana (author), Smaragdakis, G. (author), Griwodz, Carsten (author)During the last decades, public and private investments contributed to building the Internet infrastructure, including undersea cables, long-distance fiber links, broadband networks, and satellite constellations to reduce end-to-end delay. In this study, we measure the inter-city delays over the last six years, considering 17 major metropolitan...conference paper 2023

(author), van der Kooij, H. (author), Mugge, W. (author)Individuals with an upper motor neuron syndrome, e.g., stroke survivors, may have a pathological increase of passive ankle stiffness due to spasticity, that impairs ankle function and activities such as walking. To improve mobility, walking aids such as ankle-foot orthoses and orthopaedic shoes are prescribed. However, these walking aids...journal article 2023

van Iersel, L.J.J. (author), Jones, M.E.L. (author), Julien, E.A.T. (author), Murakami, Yukihiro (author)Phylogenetic networks are used to represent the evolutionary history of species. Recently, the new class of orchard networks was introduced, which were later shown to be interpretable as trees with additional horizontal arcs. This makes the network class ideal for capturing evolutionary histories that involve horizontal gene transfers. Here,...conference paper 2023

(author)In this work, we consider the self-calibration problem of joint calibration and direction-of-Arrival (DOA) estimation using acoustic sensor arrays. Unlike many previous iterative approaches, we propose solvers that can be readily used for both linear and non-linear arrays for jointly estimating the sensor gain, phase errors, and the source...journal article 2023

This development is leading to a decrease in systemic inertia and damping against electrical oscillations. This causes the introduction of new and faster dynamic phenomena. One of these phenomena is sub-synchronous control interaction ...conference paper 2023
