van Neerven, J.M.A.M. (author), Portal, Pierre (author), Sharma, Himani (author)We consider operators acting on a UMD Banach lattice X that have the same algebraic structure as the position and momentum operators associated with the harmonic oscillator (Formula Presented) acting on L<sup>2</sup>(R<sup>d</sup>). More precisely, we consider abstract harmonic oscillators of the form (Formula Presented) for tuples of...journal article 2023

Jafarian, M. (author), Mamduhi, Mohammad H. (author), Johansson, Karl H. (author)This article studies stochastic relative phase stability, i.e., stochastic phase-cohesiveness, of discrete-time phase-coupled oscillators. The stochastic phase-cohesiveness in two types of networks is studied. First, we consider oscillators coupled with 2π-periodic odd functions over underlying undirected graphs subject to both multiplicative...journal article 2023

Cai, Z. (author), Wiertlewski, M. (author)The sensation of touching virtual texture and shape can be provided to a touchscreen user by varying the friction force. Despite the saliency of the sensation, this modulated frictional force is purely passive and strictly opposes finger movement. Therefore, it is only possible to create forces along the direction of movement and this...journal article 2023

De Ridder, J. (author), Ripepi, V. (author), Aerts, C. (author), Palaversa, L. (author), Eyer, L. (author), Holl, B. (author), Audard, M. (author), Rimoldini, L. (author), Hladczuk, N.A. (author)Context. The third Gaia data release provides photometric time series covering 34 months for about 10 million stars. For many of those stars, a characterisation in Fourier space and their variability classification are also provided. This paper focuses on intermediate- to high-mass (IHM) main sequence pulsators (M'a ¥''1.3'M') of spectral...journal article 2023

van Vledder, C.A. (author), Rueda, José L. (author), Stefanov, Alexandru (author), Palensky, P. (author), Anaya-Lara, Olimpo (author), Kruimer, B. (author), Gonzalez-Loderiro, Francisco (author)Power electronic interfaced generation (PEIG) has become significantly dominant in the electrical power grid. 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

Pan, S. (author), An, Xiaomeng (author), Yu, Zheru (author), Jiang, H. (author), Makinwa, K.A.A. (author)This article presents the design and implementation of a compact CMOS RC frequency reference. It consists of a frequency-locked loop (FLL) that locks the period of a voltage-controlled oscillator (VCO) to the time an RC network takes to charge to a reference voltage. Conventionally, an RC time constant with a near-zero temperature coefficient...journal article 2023

Kawasaki, Y. (author), Minato, S. (author), Ghose, R. (author)Bulk-density ( ρ) of soil is an important indicator of soil compaction and type. A knowledge of the spatial variability of in situ soil density is important in geotechnical engineering, hydrology and agriculture. Surface geophysical methods have so far shown limited success in providing an accurate and high-resolution image of 3-D soil...journal article 2023

Rahimi Dalkhani, A. (author), Áústsdóttir, Thorbjörg (author), Gudnason, Egill Árni (author), Hersir, Gylfi Páll (author), Zhang, Xin (author), Weemstra, C. (author)Ambient noise seismic tomography has proven to be an effective tool for subsurface imaging, particularly in volcanic regions such as the Reykjanes Peninsula (RP), SW Iceland, where ambient seismic noise is ideal with isotropic illumination. The primary purpose of this study is to obtain a reliable shear wave velocity model of the RP, to get a...journal article 2023

van der Wilt, Pieter (author)The traditional Eulerian view of biomass in bioprocess modelling results in issues when modelling large-scale bioreactors in which heterogeneous conditions are common. As the field increasingly moves from “scale-up” to “scale-down” philosophy, in which such heterogeneities are included from the start of process design, accurate modelling of the...bachelor thesis 2022

Blok, Robin (author)An improvement for pedicle screws would be if the screws can directly transfer their forces to the strong cortical bone of the vertebra, rather than through the softer cancellous bone. This approach requires the creation of a curved trajectory through cancellous bone. The goal of this project is to adapt the flexible oscillating drill design of...master thesis 2022

Meekes, Bauke (author)This work proposes an energy harvesting DC-DC converter that is able to efficiently process a wide input power range from 25 mW up to 250 mW, to charge a storage device used in Internet-of-Things (IoT) applications. An interleaved boost-converter topology with two inductors is used to divide the high currents over the two branches, in order to...master thesis 2022

Son, Dongjin (author)In this work, a SPAD-based LiDAR system is studied. In particular, the system employs a direct time-of-flight (dToF) method to reconstruct a target-reflected pulses using histogram, from which the distance to the target is estimated. More particularly, a time correlated single photon counting (TCSPC) method has been used to record the flight...master thesis 2022

Vermeer, Wiggert (author)Synchronisation refers to the tendency of coupled oscillators to move in phase with one another over time, departing from their own natural frequency. This phenomenon occurs in almost all branches of science, engineering, and social life. Synchronisation is a well understood concept in classical mechanics. Quantum synchronisation involves...bachelor thesis 2022

Klyde, D.H. (author)From the Wright Flyer to fly-by-wire, the phenomenon of pilot-induced oscillations (PIO) has persisted, evolving with the complexity of the airframes and their associated flight control systems. Though airframe designers have long recognized the threat posed by PIO, each generation has been forced to address the issue whether identified in...doctoral thesis 2022

Richardson, Anthony (author)A structural firm will not invest a large sum of money in early design fase on a wind tunnel aeroelastic model to determine the displacements, forces, and moments when the dimensions of a building have only been estimated because the outcomes are only valid for that specific model. It is well-known that the outcomes are hard to determine...master thesis 2022

Ahmed, Azeem (author)The purpose of this report is to design a wave energy converter, in particular a U-oscillating water column (U-OWC), to maximize energy conversion in the low wave energy environment of Gwadar, Pakistan. At present Pakistan’s 1000km coastline is largely undeveloped and the county is devoid of any wave energy harnessing devices or studies. However...master thesis 2022

Chen, Y. (author)The scaling of CMOS technology in deep submicron process nodes is accompanied by the integration of more and more functional blocks of a system, whether digital or analog/RF, onto the same chip (i.e., system-onchip, SoC). These blocks would also place different requirements on their power supplies. To provide various static or dynamically...doctoral thesis 2022
