Chimmalgi, S. (author), Wahls, S. (author)Riemann theta functions play a crucial role in the field of nonlinear Fourier analysis, where they are used to realize inverse nonlinear Fourier transforms for periodic signals. The practical applicability of this approach has however been limited since Riemann theta functions are multi-dimensional Fourier series whose computation suffers...journal article 2023

Pinto Ribeiro, A. (author), Muscari, C. (author)Simulating entire wind farms with an actuator line model requires significant computational effort, especially if one is interested in wake dynamics and wants to resolve the tip vortices. A need to explore unconventional approaches for this kind of simulation emerges. In this work, the actuator line method is implemented within a lattice...journal article 2023

Schouhamer Immink, Kees A. (author), Weber, J.H. (author)We consider noisy communications and storage systems that are hampered by varying offset of unknown magnitude such as low-frequency signals of unknown amplitude added to the sent signal. We study and analyze a new detection method whose error performance is independent of both unknown base offset and offset's slew rate. The new method...journal article 2022

Singh, V. (author), Shevchuk, O. (author), Blanter, Y.M. (author), Steele, G.A. (author)We experimentally investigate the nonlinear response of a multilayer graphene resonator using a superconducting microwave cavity to detect its motion. The radiation pressure force is used to drive the mechanical resonator in an optomechanically induced transparency configuration. By varying the amplitudes of drive and probe tones, the...journal article 2016

Pachos-Fokialis, N. (author), Galanaki, Eleanna (author), van der Heijden, Beatrice I.J.M. (author)Previously, scholars have studied the need for implementing different human resource (HR) configurations that foster aging employees' outcomes, but there is a lack of evidence at the group level. Using the framework of Social Exchange Theory, coupled with the Selection, Optimization, and Compensation theory, we examine associations between...journal article 2023

Reda, Abel Kebede (author), Tavasszy, Lorant (author), Gebresenbet, Girma (author), Ljungberg, David (author)This paper investigates the effect of spatial and locational characteristics of establishments on freight (trip) attraction (FA/FTA) models. The authors estimated econometric models of FA and FTA as a function of the establishment attributes as well as the spatial and locational determinant variables, using establishment-level data collected...journal article 2023

Li, L. (author), Lukszo, Z. (author), Schmitz, J.E.J. (author)Hydrogen is becoming increasingly popular as a clean, secure, and affordable energy source for the future. This study develops an approach for designing a PV–battery–electrolyzer–fuel cell energy system that utilizes hydrogen as a long-term storage medium and battery as a short-term storage medium. The system is designed to supply load demand...journal article 2023

van Beinum, A.S. (author), Farah, H. (author), Wegman, F.C.M. (author), Hoogendoorn, S.P. (author)Turbulence in traffic is a commonly known phenomenon, but the exact characteristics of this phenomenon are not yet clear. Turbulence reflects individual changes in speed, headways, and lanes in the traffic stream. The current freeway design guidelines prescribe measures for handling turbulence, such as sufficient ramp spacing and spacing...journal article 2016

Zong, H. (author), Kotsonis, M. (author)An experimental characterisation study of a large-volume three-electrode plasma synthetic jet actuator (PSJA) is presented. A sequential discharge power supply system is used to activate the PSJA. Phase-locked planar particle image velocimetry (PIV) and time-resolved Schlieren imaging are used to characterise the evolution of the induced flow...journal article 2016

Dekker, S.H. (author), Wurzel, G. (author), Alderliesten, R.C. (author)Fatigue life is a random variable. The reliability of a conservative fatigue life prediction for a component in the helicopter dynamic system thus needs to be substantiated. A standard analytical substantiation method uses averaged manoeuvre loads instead of seeing manoeuvre loads as a random variable whose distribution is estimated with limited...journal article 2016

Hernandez Santana, M. (author), Grande, A.M. (author), van der Zwaag, S. (author), Garcia, Santiago J. (author)Broadband dielectric spectroscopy (BDS) is introduced as a new and powerful technique to monitor network and macroscale damage healing in an elastomer. For the proof of concept, a partially cured sulfur-cured natural rubber (NR) containing reversible disulfides as the healing moiety was employed. The forms of damage healed and monitored were an...journal article 2016

Parra Gómez, L.J. (author), Muraro, S. (author), Jommi, C. (author)A relevant part of the geotechnical infrastructure in the north of Europe and overseas is built on soft organic soils, including peat. Peat is extremely vulnerable to climate-related hazards as increased temperature accelerates drying, shrinkage and decomposition of the organic matter. Peat exhibits dramatic changes in volume with changes in...journal article 2023

Musta, E. (author), Pratelli, M. (author), Trevisan, D. (author)We investigate the problems of drift estimation for a shifted Brownian motion and intensity estimation for a Cox process on a finite interval [0,T], when the risk is given by the energy functional associated to some fractional Sobolev space . In both situations, Cramér–Rao lower bounds are obtained, entailing in particular that no unbiased...journal article 2017

Stouffs, R.M.F.A. (author)A description grammar, in conjunction with a shape grammar, serves to generate verbal descriptions of designs, next to the spatial descriptions. These verbal descriptions can also assist in guiding the generative process. This paper revisits applications of description grammars found in literature and demonstrates how they can be recast and...journal article 2016

Vahid Belarghou, A. (author), Idema, T. (author)Membrane tubes and tubular networks are ubiquitous in living cells. Inclusions like proteins are vital for both the stability and the dynamics of such networks. These inclusions interact via the curvature deformations they impose on the membrane. We analytically study the resulting membrane mediated interactions in strongly curved tubular...journal article 2016

Scheepmaker, G.M. (author), Goverde, R.M.P. (author), Kroon, Leo (author)The energy consumption of trains is highly efficient due to the low friction between steel wheels and rails, although the efficiency is also influenced largely by the driving strategy applied and the scheduled running times in the timetable. Optimal energy-efficient driving strategies can reduce operating costs significantly and contribute to a...journal article 2016
