This thesis is part of a greater effort to use machine learning for the development of flexible and universal unresolved-scale models in large eddy simulation (LES). The novelty in the current work is that a neural network learns to predict the integral forms of the unresolved-scale terms directly without a priori assumptions on the underlying...

LiDAR technologies are used to measure point cloud data of the earth's surface. The usage of LiDAR allows for the fast collections of massive data sets. The AHN2 point cloud data set, part of Rijkswaterstaats initiative to map the surface of the Netherlands, contains 639 478 217 460 points. For efficient visualization in web viewers, these...

One in four people in the world will be affected by mental or neurological disorders at some point in their lives (WHO, 2001). Around 450 million people currently suffer from such conditions, placing mental disorders among the leading causes of ill- health and disability worldwide, in particular in low-income countries, where many barriers to...

Current brain simulators do no scale linearly to realistic problem sizes (e.g. >100,000 neurons), which makes them impractical for researchers. The goal of the thesis is to explore the use of true multi-GPU acceleration on computationally challenging brain models and to assess the scalability of such models given sufficient access to multi...

The coastline of the United States has been threatened by significant erosion for the past decades. A study in 2000 predicted that 25% of the houses located within 150 meters of the shoreline will be destroyed by erosion in 2060. The east coast of the US experiences an average erosion rate of roughly one meter per year. Moreover, the Atlantic...

The subsurface is often modelled as multiple homogeneous soil layers. In reality, the soil properties of these layers are heterogeneous and spatially variable, making it difficult to properly deduct the engineering properties that are required in the design of geotechnical structures. This leads to uncertainty in the design. The probabilistic...

After more than 85 years, the iconic Afsluitdijk is in need of a reinforcement. During the latest safety assessment of Rijkswaterstaat the dike did not meet the standards at two components; the amount of wave overtopping (>10 l/m/s) and armour stability. This research goes into detail about the overtopping on the Afsluitdijk. In the new...

With the growing population and industrial development, there is more stress on natural water resources. Additionally, environmental laws make the disposal of waste streams from industries difficult. In this scenario, it is crucial to treat waste streams to recover water and possibly minerals, for reuse in the industry, reducing the dependency...

The continuous pursuit of reducing drag in many speed sports, such as cycling and ice-skating, demands novel approaches to gain further insight into flow phenomena around athletes. In recent years, the Ring of Fire measurement technique has emerged as a feasible option to visualise and analyse flow structures of transiting objects based on...

Small scale inland shipping, especially in the case of transported containers, is used only marginally compared to its capacity. The small inland waterways have abundant capacity to accommodate up to 700 percent more transport. On the other hand, road based container transport is cause for external damages in the form of congestion, emissions...

Occlusion and crossing in Multi-Person Tracking always influence the tracking results. In this paper, we show how deep Re-Identification (ReID), which aims at matching pedestrians across non-overlapping video cameras, can be used to improve the occlusion problem on tracking. The learned ReID feature is more robust than other features used in...

Optical flow is a representation of projected real-world motion of the object between two consecutive images. The optical flow measures the pixel displacement on the image coordinate plane. However, it does not reveal the motion in depth explicitly, which could be useful as input in some tasks such as vehicle tracking. To extend the original...

To counteract the effect of climate change, a global agreement was put into force in 2016, aiming to limit the increase in average global warming and reduce greenhouse gas emissions. In that respect, European countries are investing in cleaner sources of energy and predominantly offshore wind, which has seen a rapid growth over the last years....

Genoa is positioned on a very narrow piece of land, squeezed in between the mountains and the sea. This provides a topography in which the port and the city are forced to live very close to each other. Whereas in other port cities the port recedes itself from the city center, this is not possible in Genoa due the the mountainous hinterland. Thus...

Due to the removal of mangrove forests, coastal zones can suffer from severe erosion. One of the proposed solutions is the construction of permeable structures. This study aims to optimise the design of permeable (brushwood) structures in order to restore the sediment balance and encourage mangrove re-establishment on tropical mud coasts....

As the elderly world population increases, caregivers are switching to remote care and monitoring solutions to enable their patients to live autonomously at home for as long as possible. Such services are based on detecting and recognizing Activities of Daily Living (ADL) by using diverse types of sensors at the elder's home that transmit...

In the past years, climate change has caused an increasing number of extreme weather events. In the Netherlands this is, for instance, reflected by the growing amount of extreme rainfall events. This creates big issues for water management authorities like water boards. Water boards are often responsible for local streams, that cannot handle the...

As of 2040, Energy Information Administration (EIA) expects an increase of 28% in world energy consump- tion. The majority of this consumption is projected to account from developing countries such as India, China and other third world countries since the economy is increasing rapidly. [3]
In order to overcome this fast increase, the human...

The urgency to innovate for organisational survival has become increasingly recognised, with the result that innovation has conquered a position high on the management agenda. However, the unfamiliarity around innovation poses a challenge for innovation management. No unique solution exists to building a successful innovation approach, such that...

Agile methods seem to be the answer for today’s turbulent industries, and with it roots in software development, coincides neatly with the increasingly digital world we live in. ABN AMRO also decided to implement a large scale agile framework tailored to their company. Agile methodologies are known to work well at small scale and in an IT...
