The cyclic nature of integrated coastal management embodies a learning-based approach. Pilot projects in particular have an explicit learning objective. Whereas learning from (changing) physical aspects is often part of the monitoring and evaluation phase within the ICM cycle, learning from the experiences of people is not structurally...

Waterways and lakes in low-lying delta areas require regular dredging for maintenance. Reuse of dredged sediments has been proposed for various applications. However, directly after dredging the physical characteristics of these sediments make them generally unsuited for immediate reuse. They are often placed on land, where they are allowed to...

Wind turbines are operating under very complex and uncontrolled environmental conditions, including atmospheric turbulence, atmospheric boundary layer effects, directional and spatial variations in wind shear, etc. Over the past decades, the size of a commercial wind turbine has increased considerably. All the complex and uncontrolled conditions...

Marked differences occur between modelling in scientific hydraulic research, in hydraulic engineering and in public decision making. This study reviews ifferences in the required accuracy of model results and differences in the choice between physical and numerical modelling. Physical models are used for studying elementary processes and their...

Modelling urban flood dynamics requires proper handling of a number of complex urban features. Although high-resolution topographic data can nowadays be obtained from aerial LiDAR surveys, such top-view LiDAR data still have difficulties to represent some key components of urban features. Incorrectly representing features like underpasses...

This paper presents a fully experimental study on melting, flow and weld strength development during ultrasonic welding of CF/PPS composites with integrated triangular energy directors. The main goal of this research was assessing whether the heating time to achieve maximum weld strength could be significantly reduced as compared to...

Reducing the power consumption of low-power short-range receivers is of critical importance for biomedical and Internet-of-Things applications. Two interesting degrees of freedom (or properties) that have not been fully exploited in the pursuit of low power consumption are the antenna impedance and the phase-only modulation property of FSK/PSK...

The number of plug-in electric vehicles (PEVs) is likely to increase in the near future and these vehicles will probably be connected to the electric grid most of the day time. PEVs are interesting options to provide a wide variety of services such as primary frequency control (PFC), because they are able to quickly control their active power...

With the rapid improvements in digital communication technologies, distributing high-definition visual information has become more widespread. However, the available technologies were not sufficient to support the rising demand for high-definition video. This situation is further complicated when the network resources such as the available...

New European energy policies have set a goal of a high share of renewable energy in electricity markets. In the presence of high levels of renewable generation, and especially wind, there is more uncertainty in the supply. It is natural, that volatility in energy production induces the volatility in energy prices. This can create incentives for...

The spatial and temporal response characteristics of a laminar separation bubble to impulsive forcing are investigated by means of time-resolved particle image velocimetry and linear stability theory. A two-dimensional impulsive disturbance is introduced with an alternating current dielectric barrier discharge plasma actuator, exciting...

The large volume production of flexible electronics by solution based roll-to-roll (R2R) manufacturing technologies is a promising upscaling strategy for the organic electronics industry. Typical optoelectronic devices like organic light emitting diodes (OLEDs) consist of a complex stack of functional layers. Solution deposition of these...

Firefly Algorithm (FA, for short) is inspired by the social behavior of fireflies and their phenomenon of bioluminescent communication. Based on the fundamentals of FA, two improved strategies are proposed to conduct size and topology optimization for trusses with discrete design variables. Firstly, development of structural topology...

This paper presents a systematic review of the concept of resilience in the field of disaster management, with a focus on the use of indicators and the inclusion of social justice considerations. The literature is reviewed with reference to various definitions of resilience, the relation between concepts of resilience and vulnerability, the...

Context is a crucial concept in architecture, despite the frequent ambiguity around its use. It is present in many architectural thoughts and discussions, while a critical discursive reflection is absent from contemporary architectural theory and practice. Situated within this schizophrenic condition in which the notion is both absent and...

Passive seismics is the set of applications that endeavours the exploration of the
Earth’s mechanical properties using naturally occurring sources in the subsurface.
Conventional imaging of the subsurface is achieved with the aid of reflection
surveys of body waves from the surface. Passive seismics offers the possibility
to...

Large-scale hydrological modelling of flood hazards requires adequate extreme discharge data. In practise, models based on physics are applied alongside those utilizing only statistical analysis. The former require enormous computational power, while the latter are mostly limited in accuracy and spatial coverage. In this paper we introduce an...

Biofuel production is not cost competitive and thus requires governmental intervention. The effect of the institutional framework on the development of the biofuel sector is not yet well understood. This paper aims to analyze how biofuel production and production capacity could have evolved in Germany in the period 1992–2014. The effects of...
