Reconstruction of the 1374 Rhine river flood event around Cologne region using 1D-2D coupled hydraulic modelling approach

Reconstructions of the most severe historic flood events contribute to improved quantification of design discharges corresponding to large return periods. Reducing the uncertainty of design discharges has a great significance in constructing proper flood defences to protect the hinterland from future flooding. However, reconstructions of the...

The discharge magnitude of the 1374 millennium flood event in the Rhine river

From wastewater to resource

Eighty percent of wastewater is left untreated or not reused, exacerbating the water quality challenge, especially in vulnerable communities. This Voices asks: how can we improve wastewater management and convert wastewater into a resource?

Design Considerations for Brushwood Fences Concerning Bathymetry and Fence Locations

Wooden fences are nature-based supporting structures to restore mangroves in the Mekong Delta. The hydraulic functioning of wooden fences was studied in previous studies. However, the role of bathymetry in the dissipation and damping of waves by wooden fences has not been studied yet. Thus, in this study, a numerical approach is used to find...

An Efficient Modeling Approach for Probabilistic Assessments of Present-Day and Future Fluvial Flooding

Risk-informed flood risk management requires a comprehensive and quantitative risk assessment, which often demands multiple (thousands of) river and flood model simulations. Performing such a large number of model simulations is a challenge, especially for large, complex river systems (e.g., Mekong) due to the associated computational and...

Development of an Efficient Modelling Approach to Support Economically and Socially Acceptable Flood Risk Reduction in Coastal Cities: Can Tho City, Mekong Delta, Vietnam

Flooding is one of the most frequently occurring and damaging natural disasters worldwide. Quantitative flood risk management (FRM) in the modern context demands statistically robust approaches (e.g. probabilistic) due to the need to deal with complex uncertainties. However, probabilistic estimates often involve ensemble 2D hydraulic model runs...

A Fully Synthesizable Fractional-N MDLL With Zero-Order Interpolation-Based DTC Nonlinearity Calibration and Two-Step Hybrid Phase Offset Calibration

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...

Instant flood risk modelling (Inform) tool for co-design of flood risk management strategies with stakeholders in Can Tho city, Vietnam

Flood risk reduction strategies play an important role in flood risk management (FRM) and these strategies are being co-designed with the engagement of the stakeholder through multiple consultations and co-designing sessions. Effective participation of stakeholders in interactive work sessions requires fast and accurate modeling systems with...

Light-In-Flight Imaging by a Silicon Image Sensor: Toward the Theoretical Highest Frame Rate

Light in flight was captured by a single shot of a newly developed backside-illuminated multi-collection-gate image sensor at a frame interval of 10 ns without high-speed gating devices such as a streak camera or post data processes. This paper reports the achievement and further evolution of the image sensor toward the theoretical temporal...

Transformation of the Baudartius college into a Film & Music center

Zutphen, one of the oldest city in the Netherlands that started as a Germanic settlement, then a trading city and now a medium-sized city is currently dealing with vacancy, dejuvenation and an aging population . Vacancy, though not as high as other cities in the Netherlands, affects neighbourhoods next to the old city centre. The city centre ...

An effective modelling approach to support probabilistic flood forecasting in coastal cities-Case study: Can Tho, Mekong Delta, Vietnam

Probabilistic flood forecasting requires flood models that are simple and fast. Many of the modelling applications in the literature tend to be complex and slow, making them unsuitable for probabilistic applications which require thousands of individual simulations. This article focusses on the development of such a modelling approach to...

Mechanical Tuning of Through-Molecule Conductance in a Conjugated Calix[4]pyrrole

A conformationally flexible calix[4]pyrrole possessing a conjugated electronic structure (an N-substituted oxoporphyrinogen (OxP) related to porphyrin) was used to investigate the influence of mechanical stretching on the single-molecule conductance of these molecules using the mechanically-controlled break junction (MCBJ) technique. The...

Towards A New Tensegrity System: for Large-span Structures

Throughout the long history of architecture, the effect of gravity is always present in any structures. Surprisingly in tensegrity composition, this primary law of nature seems to be absent. This is because the discontinuous set of struts in the continuous network of proportionally thin cables makes the structures look like floating in the air....

Application of UHPC in Long Span Bridge Design

In the last few decades great progression has been made in the research and development of a fairly new type of concrete called ultra-high performance concrete (UHPC). This high-tech material has excellent material properties compared to conventional concrete and has the potential to make more slender and lighter structures. However the material...

Designing the User Experience for the Future Keyboard

Future Keyboard offers users a rich musical experience by enabling them to connect their keyboard with web-enabled media devices. By conducting research into the desired user experiences and suitable interface solutions, afterRecord has been developed as the style guide application for new apps. It fits with musical experiences for improvement...

New upper bounds on the separating redundancy of linear block codes

Most decoding algorithms of linear codes, in general, are designed to correct or detect errors. However, many channels cause erasures in addition to errors. In principle, decoding over such channels can be accomplished by deleting the erased symbols and decoding the resulting vector with respect to a punctured code. For any given linear code and...
