Hinborch, M. (author)
The flood defence in the historical town centre of Dordrecht is situated in the Voorstraat, which is a busy shopping street. The dike itself is too low at some places, but with a system of flood stop logs in the doors of buildings along the street some extra height can be reached. The reliability of the stop log system is doubted however, so...

The main objective of this thesis is determining whether the simplified, qualitative risk assessment models and solutions initiatives of Control Banding (CB) can be integrated within the multidisciplinary requirements of occupational risk management. This was achieving practical primary prevention that assists non-experts in obtaining the...

Large infrastructure projects in the Netherlands are often subject to discussion due to large time and cost overruns. Project management instruments are developed by the projects for the efficient management of time, cost and scope. These collections of methods, tools and approaches are often modified and further developed when projects face...

This primer describes some of the causes of coastal erosion and tries to put into perspective their scale and consequences. There are no uniform causes, just as there are no uniform solutions. Erosion tends to be site-specific. Yet, with careful observation and measurement, a particular problem can be placed in context and draw from the...

To enhance the thermal stability, B4C diffusion barrier layers are often added to Mo/Si multilayer structures for extreme ultraviolet optics. Knowledge about the chemical interaction between B4C and Mo or Si, however is largely lacking. Therefore, the chemical processes during annealing up to 600?°C of a Mo/B4C/Si layered structure have been...

Oxidation behavior of the uncoated base, Ni–Al coated and Re–Cr-Ni plus Ni–Al coated single-crystal (SC) Ni-based TMS-82+ superalloy is studied under cyclic air at 900ºC for 200 h to assess the oxidation resistance. Regardless of the coating processing, Ni–Al coating is effective in improving the oxidation resistance due to the formation of a...

The Eastern Scheldt tidal basin and its ebb tidal delta have changed drastically in the recent centuries under the influence of natural processes and human interventions. A Storm Surge Barrier, one of constructions within framework of Delta Project in the Eastern Scheldt, is considered as the largest impact to changes in hydrodynamics and...

The second Delta-committee (September 2008) foresees difficulty in resolving flood safety issues for Rotterdam and Dordrecht if high river runoffs are still running through the New Waterway. A new safety issue, induced by climate changes, lies in the combination of closed sea defensives and relatively high river runoffs at the same time. A...

We report the realization of extremely small single quantum dots in p-type silicon nanowires, defined by Schottky tunnel barriers with Ni and NiSi contacts. Despite their ultrasmall size the NiSi–Si–NiSi nanowire quantum dots readily allow spectroscopy of at least ten consecutive holes, and additionally they display a pronounced excited-state...

The aim of this research is to determine to what extend the scour holes limit the sediment transport through the Eastern Scheldt storm surge barrier and whether or not human adaptations, like sand-nourishments in the scour holes, can have a positive effect on the sediment import. To investigate these scenarios a numerical model (Delft3D) is used...

Thermal barrier coatings (TBCs) are applied in gas turbines to enhance their thermal efficiency by isolating the metallic components from the aggressive hot gas. TBC lifetime is limited by damage processes originating at internal interfaces, which may ultimately lead to delamination and spallation. In the present thesis constitutive models are...

Physical model tests were undertaken at HR Wallingford to address gaps in the knowledge of the failure process of shingle barrier beaches. During these tests, numerous factors were considered such as sediment characteristics, the type of waves (storm or swell), and beach crest geometry (height, width, back slope). This technical note summarises...

The Atacama Large Millimeter/submillimeter Array (ALMA) is an astronomical observatory that is being built on a 5000 m altitude plateau in Chile to perform heterodyne measurements in the frequency range of 30 to 950 GHz. These measurements will reveal the presence of characteristic molecules that tell us more about the evolution of the early...

For the first time, an analytical model of arbitrarily shallow p-n junctions is presented. Depending on the junction depth, electrical characteristics of ultrashallow p-n junctions can vary from the characteristics of standard Schottky diodes to standard deep p-n junctions. This model successfully unifies the standard Schottky and p-n diode...

De Kasteeltraverse in Helmond is een drukke weg dwars door het centrum. De weg telt 2 x 2 rijstroken, op drukke dagen rijden er ongeveer 25.000 motorvoertuigen over de weg. Ter hoogte van het Kasteel van Helmond ligt deze weg op een viaduct. De weg heeft een regionale stroomfunctie, een stedelijke ontsluitingsfunctie en is ook belangrijk voor de...

This report scopes the state-of-the-art understanding of barrier beaches. It sets the foundations for improving the science and application of management tools, and for developing sound management guidance. Such guidance will help flood and coastal erosion risk management policy makers and practitioners make better decisions on barrier beach...

The present paper is concerned with the processes of coastal barrier breaching with focus on the breach initiation induced by high activity of tropical cyclones in the northern and central coast of Vietnam. The breach initiation by the response of coastal barriers during storm surges can also be a common practice encountered in many coasts...
