(author)Advances in CMOS technologies and circuit techniques have led to the development of continuous-time delta-sigma modulators (CTΔ Σ Ms) that sample at gigahertz (GHz) frequencies and achieve high linearity [-100 dBc and >120 dBFS spurious-free dynamic ranges (SFDRs)] in wide bandwidths (>100 MHz). However, at low frequencies (≤ 10 MHz),...journal article 2024

Romanos, C. (author)The role played by the Mekong River in the organization of land and people is inextricably linked with a particular spatial category. The concept of the hydrological catchment extends the space of the river far beyond the limits of the river’s perennial waterbodies, to encompass vast areas inhabited by millions of people speaking different...doctoral thesis 2023

Chowdhury, M. Kifayath (author), Blom, A. (author), Ylla Arbos, C. (author), Verbeek, Merel C. (author), Schropp, Max H.I. (author), Schielen, R.M.J. (author)A bifurcation in an engineered river system (i.e., fixed planform and width) has fewer degrees of freedom in its response to interventions and natural changes than a natural bifurcation system. Our objective is to provide insight into how a bifurcation in an engineered river responds to peak flows and human interventions. To this end, we analyze...journal article 2023

den Hartog, Harry (author)Waterways played a crucial role in the emergence of Shanghai as a cosmopolitan city and world port. Over the years the spatial and functional relationships between the city and ports and hinterland have been changing continuously. In Shanghai, like other port cities, almost all ports and related industries are placed out beyond the urban fringes...journal article 2023

Xie, Weiming (author), Sun, J. (author), Guo, Leicheng (author), Xu, Fan (author), Wang, Xianye (author), Ji, Hongyu (author), Fan, Yaoshen (author), Wang, Zhengbing (author), He, Qing (author)Coastal tidal flats provide valuable ecosystems, but are highly sensitive to tidal dynamics, sea-level rise, and human activities. Tidal inundation depth and frequency are known to affect tidal flat morphodynamics. However, the causes, processes and extent remain uncertain, particularly given the associated changes in sediment availability. In...journal article 2023

(author)At a global scale, intertidal areas are being reclaimed for agriculture as well as urban expansion, imposing high human pressure on the coastal zone. The Ganges-Brahmaputra Delta (GBD) is an exponent of this development. In this delta, land reclamation accelerated in the 1960's to 1980's, when polders were constructed in areas subject to...journal article 2023

(Ton) (author)Effects of sea-level rise (SLR) on future peak water levels in tidal deltas and estuaries are largely unknown, despite these areas being densely populated and at high risk of flooding. While the rates of SLR accelerate, many channels simultaneously experience channel deepening for navigation. With globally decreasing sediment supplies, most...journal article 2023

Rout, Samprajani (author), Monna, G.L.E. (author), Pareschi, Fabio (author), Setti, Gianluca (author), Serdijn, W.A. (author)The key challenges in designing a multi-channel biosignal acquisition system for an ambulatory or invasive medical application with a high channel count are reducing the power consumption, area consumption and the outgoing wire count. This article proposes a spread-spectrum modulated biosignal acquisition system using a shared amplifier and...journal article 2023

Tang, Z. (author), Pan, S. (author), Grubor, M. (author), Makinwa, K.A.A. (author)This article presents a sub-1 V bipolar junction transistor (BJT)-based temperature sensor that achieves both high accuracy and high energy efficiency. To avoid the extra headroom required by conventional current sources, the sensor’s diode-connected BJTs are biased by precharging sampling capacitors to the supply voltage and then discharging...journal article 2023

Nijhuis, S. (author), Sun, Yimin (author), Cannatella, D. (author), Xie, G. (author)Adaptive urban transformations employ landscape-based regional design as an integrative and multiscale design and planning approach for sustainable urban development. In this approach, natural and urban dynamics as derived from systems analysis set the pace and nature of adaptation. This chapter presents an initial strategy for adaptive urban...book chapter 2023

(author)Microbial pathogens in urban floodwaters pose risks to human health, potentially causing diseases such as diarrhea. However, the disease burden related to urban traffic exposure from citizens passing through floodwaters is not easily quantified and therefore not included in many studies. Notably, this problem has received little attention in...journal article 2023
