This article describes a discrete-time zoom analog-to-digital converter (ADC) intended for audio applications. It uses a coarse 5-bit SAR ADC in tandem with a fine third-order delta-sigma modulator (Δ Σ M) to efficiently obtain a high dynamic range. To minimize its over-sampling ratio (OSR) and, thus, its digital power consumption, the modulator...

The research aims to provide an understanding of an urbanizing delta in which different scales, times, and domains are related to each other; and to examine how this understanding can be used in a planning and design process in a rapidly urbanizing delta. A mapping method is developed according to the key notions in the understanding of urban...

This thesis captures the calibration of a FX hybrid model: The FX Black-Scholes Hull-White model. The main focus is on the calibration of the parameters in the Hull-White process: The mean reversion and the volatility parameter. The latter is commonly calibrated as a time-dependent parameter, whilst the mean reversion parameter is not. This...

Decision-makers in low-lying coastal zones are confronted with uncertain developments around flood risk.These drivers are surrounded by large uncertainties, which requires delta management to be adaptive. This research offers insights about adaptive delta management for the Rhine-Meuse estuary from three perspectives: a physical, a socio...

This thesis presents a BJT-based CMOS temperature-to-digital converter (TDC). With a continuous-time readout, the TDC avoids the kT/C noise limit incurred by previous discrete-time (switched-capacitor) TDCs. An energy-efficient BJT front-end generates single PTAT and CTAT currents for being digitized by a delta-sigma modulator through a linear...

This report investigates the long-term morphological changes caused by the DELTA 21 project at the northern side, including the large scale morphological development with Delft3D model and at local scale the coastline deformation with UNIBEST-CL model. The necessity of the layout design improvement of DELTA 21 is analyzed by comparing different...

In recent years, there has been an increasing need for solutions against the threats that SLR and climate change represent for coastal systems, especially in low lying areas like the SW Dutch coast. Simultaneously, awareness of the impacts that human activities have on natural environments has surged. Integrated and sustainable solutions are...

The functioning of the brain depends on the interplay between a large number of neurons. To understand the information processing in neuronal networks, we need tools to record the electrical activity of cells at high resolution. Microelectrode arrays (MEAs) are predominantly used to measure neuronal activity<br/>at high spatial and temporal...

A novel approach is investigated to extend the range of measurable velocities by 3D-PTV systems. The method is specifically conceived for robotic volumetric PTV measurements, but it has applications for other similar techniques. The multi-Δt method relies upon combining the information from two or more sets of double-frame images with pulse...

The phase “water, water everywhere but too much or too little” aptly explains the current situation of many global cities. Within the numerous challenges due to Climate change and Urbanisation, water ranks the highest as a risk to the society. This risk ranges from water related catastrophes like floods to availability of portable water to the...

Long-term planning in urbanizing deltas has to deal with deep uncertainties in socio-economic development and climate change. Adaptive Delta Management (ADM) has been developed as an approach that acknowledges these and similar uncertainties. The Bangladesh Delta Plan 2100 has, in principle, adopted the ADM approach, and it recognizes general...

The Pearl River Delta region includes nine cities in Guangzhou, Foshan, Zhaoqing, Shenzhen, Dongguan, Huizhou, Zhuhai, Zhongshan and Jiangmen in Guangdong Province, with a total area of 56,000 square kilometers. It is one of the three largest urban agglomerations in China with the most developed industry and the densest population. Among them,...

According to the European Environment Agency (2016, pp. 137–140) annual mean river flow and the frequency of fluvial floods will have increased by 20% before the year 2100, in North-western Europe. It had been postulated in media in reports (De Ingenieur, 2014; „MIRT-verkenning Grevelingen”, 2012; Slootjes et al., 2010; Slootjes, 2013; Lammers,...

The People's Republic of China experienced large socio-economic development over the last decades, which was mainly concentrated in coastal regions. Jiangsu Province is among these regions, which shows large socio-economic differences between north and south. The Chinese Central Government has allocated Binhai County as a new coastal development...

Delta cities all around the world are under pressure from different forms of climate change effects. Soil subsidence as a result of peat oxidation, and anthropogenic loading of the soil. The soil in many of the heavily urbanised deltas around the world is subsiding faster than the see level is rising as a result of climate change. Few people are...

Coastal retreat problems occur in many deltas over the world. Coastal features are not constant over time and are affected by sea level rise, river runoff, sediment supply, wave and tidal energy, underlying geology and climate. In addition, human activities profoundly influence the coastal processes as a result of changing natural patterns of...

This thesis aims to come up with a preliminary design for the in- and outlet structure, in which pump-turbines are housed, of the energy storage lake within the Delta21 plan. The goal is to come up with a feasible, cost-effective and lasting solution, that can store green energy, pump out 10 000 m<sup>3</sup>/s of water and retain design storms,...

Today’s systems-on-chip (SOCs) and microprocessors are complex systems that require multiple temperature sensors to monitor temperature variations in multiple spots on a single silicon die. For such thermal management applications, specialized compact and fast temperature sensors are required. This is necessary because executing an intensive...

This paper presents a CMOS image sensor (CIS) with a zoom ADC, to quantize in-pixel temperature sensors, as well as for faster readout speed of the image pixels while maintaining low quantization noise. The proposed 15 bit zoom ADC has a 4 bit Unit Capacitor Array (UCA) SAR and a 13 bit incremental 2<sup>nd</sup>-order delta-sigma ADC (DSADC)...

The purpose of this paper is to investigate the two-capacitor paradox using circuit models developed in the analysis of circuits that include nanoelectronic single-electron tunneling devices. The two-capacitor paradox, in which it seems that energy is not conserved in a simple circuit consisting of two capacitors in parallel separated by an...
