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...

The river Waal is part of an economic important transport-corridor that connects the ports of Antwerp, Rotterdam and Amsterdam to Germany. Ongoing processes such as (1) climate change, (2) large scale river bed erosion and (3) up-scaling of vessels threaten the future navigability of the river. This will lead to massive economic damages as taken...

Basin tests were performed at the Aalto Ice Tank to gather data on ice-structure action and interaction from ice failing against a vertically sided cylindrical pile. The tests were performed with a real-time hybrid test setup, which combined physical and numerical components to simulate a range of test structures in real-time. The dataset...

This article presents a low-jitter and low-spur charge-sampling phase-locked loop (CSPLL). A charge-domain sub-sampling phase detector is introduced to achieve a high phase-detection gain and to reduce the PLL in-band phase noise. Even without employing any power-hungry isolation buffers, the proposed phase detector dramatically suppresses...

The controls of most power electronic inverters connected to an electrical power system (EPS) rely on the precise determination of the voltage magnitude, frequency, and phase angle at the point of common coupling. One of the most widely used approaches for measuring these quantities is the phase-locked loop (PLL); however, the precision of this...

In this article, we present a 4.5-5.1-GHz fractional-N digitally intensive phase-locked loop (DPLL) capable of maintaining its performance in face of a large supply ripple, thus enabling a direct connection to a switched-mode dc-dc converter. Supply pushing of its inductor-capacitor (LC) oscillator is suppressed by properly replicating the...

The Material Point Method (MPM) has been gaining increasing popularity as an appropriate approach to the solution of coupled hydro-mechanical problems involving large deformations. This study extends the implicit GIMP-patch method for coupled poroelastic problems recently proposed by Zheng et al. (2021b) to tackle large-deformation problems...

The objective of this research is to design and evaluate a new type of rolling gate for the Western lock (Westsluis) in Terneuzen, for which all sensitive and heavily loaded mechanical parts are both easily accessible and located above water. Having all mechanical parts above water not only makes them easier to inspect and maintain, but it also...

Two current assumptions of the Zeesluisformulering (ZSF) regarding a homogeneous lock density and instantaneous shipping are tested against refined descriptions according to literature: a stratified lock density and shipping according the continuity approach. These are implemented into a conceptual model constructed in Python, after which...

With the emergence of new communication standards like Fifth-­Generation New Radio (5G NR), technologies are being developed to exploit millimeter­ wave (mm-­wave) frequency bands from 30­300 GHz, for their advantage of high bandwidth availability. Generation of carrier frequencies for these mm-­wave applications imposes a challenging...

The Port of Antwerp is the second-largest container port in Europe. The rising demand for container transport requires significant investments in infrastructure projects. Macomi helps the Port of Antwerp to determine the effect of different projects on the throughput of the port using simulation. In this thesis, the aim is to create algorithms...

A large part of the Dutch plastic waste is currently incinerated, with a high amount of greenhouse gas emissions as a consequence. If recycling is done efficiently, it could provide environmental benefit over energy recovery through incineration, especially in a low carbon economy where renewable energy generation becomes the new status quo....

Interactions between tidal migration and the encounter of mean motion resonances (MMRs) have widely been used in attempts to explain unexpectedly young surfaces and high free eccentricities of moons. A driving variable in this process is the planetary quality factor (Q$), which has so far been assumed to be constant throughout the system....

“<i>A ruptured AAA [Abdominal Aortic Aneurysm] is the 15th leading cause of death in the country, and the 10th leading cause of death in men older than 55</i>” in the United States, states Singh (n.d.), in the Society for Vascular Surgeons. Such Abdominal Aortic Aneurysms (AAA, see Figure 2.2) are increasingly treated by...

The ever growing world population - 10 billion by 2050 - brings many challenges to the table. One of the most imminent is the way we handle and take care of our planets natural resources. More people means more needs. How do are we going provide for all these people? Over the past decades, we have reached a general consensus that our planet is a...

There is a lot of uncertainty in climate change developments, and therefore in its consequences. For the flood defence system of the Netherlands, an important consequence of climate change is the sea level rise. Marine locks are large, rigid, and intricate structures, with a required lifespan of at least 100 years, for which often design...

In this paper, a fully-synthesizable digital-to-time (DTC)-based fractional-N multiplying delay-locked loop,(MDLL) is presented. Noise and linearity of synthesizable DTCs are analyzed, and a two-stage synthesizable DTC is proposed in which a path-selection DTC is used as the coarse stage and a variable-slope DTC is used as the fine stage. To...

A novel approach is devised for the quantification of systematic uncertainty due to peak locking in particle image velocimetry (PIV), which also leads to correction of the peak-locking errors. The approach, applicable to statistical flow properties such as time-averaged velocity and Reynolds stresses, relies on image recordings with multiple...

In het Nederlandse wegverkeer is veel vertraging. Een vermindering van het verkeer zorgt ook voor een vermindering van die vertraging. Dit kan bereikt worden door maatregelen als beprijzing of spitsrechten. Het verkeerssysteem is één samenhangend systeem over grote afstanden. Om de effecten van deze maatregelen op netwerkschaal te beoordelen,...

This paper presents a mathematical analysis of an extended model describing a sea ice-induced frequency lock-in for vertically sided offshore structures. A simple Euler–Bernoulli beam as model for the offshore structure is used, and a moving boundary between an ice floe and the structure itself is introduced. A nonlinear equation for the beam...
