Although the Dutch energy supply is gradually progressing from fossil fuels to renewable energy sources, the consequences for the grid are becoming increasingly evident. Meanwhile, the gas extraction from the Groningen natural gas reserve is de- clining as the induced earthquakes in the northern Netherlands persist. Hydrogen, as a flexible...

In regions which experience arctic conditions, structures like offshore wind turbines, oil-platforms, light houses, piers and bridges suffer from abrasion by moving ice sheets. This results in challenging maintenance and repair works. At the ice-structure interface, several mechanisms exist which are responsible for the wear of concrete such as:...

This report is written with the aim to evaluate a possible port expansion in the port of San Vicente, Chile. In order to achieve this a thorough analysis on the port operations, hydrodynamical analysis using Delft3D and a bottleneck analysis on the infrastructure have been executed. A preliminary design for the port expansion is created. This...

The Kathmandu Valley in Nepal is facing the combined effects of population growth, rapid urbanization, economic development, and climate change. This results in serious water management challenges: growing freshwater demands, declining water tables, drying of streams, and deteriorating water quality. Insufficient surface water supplies have led...

Like other cities in Kathmandu Valley, Bhaktapur faces rapid urbanisation and population growth. Unsafe, new settlements are partly located at the floodplains and the government lags behind in implementing proper land-use policy to control unrestrained settlement. The rivers are not only constrained by uncontrolled settlements, but also by...

Heineken's goal with respect to safety is to reduce the number of accidents to zero. Such a drastic reduction can only be achieved by considering safety as early as in the design phase, when most impact can be made. Therefore, the purpose of this research is to enable the easy generation of different design concepts and evaluate them with regard...

Delamination is an important damage mechanism in composite materials. A correct prediction of its behaviour is of great importance in the design of aerospace composite structures. Nevertheless, when using simple numerical models which do not account for the delamination migrating to other interfaces or other intralaminar damage mechanisms, the...

The convection section of fired heaters consists of finned tubes to enhance heat transfer. However, finned tubes make heat transfer in the convection section of fired heaters considerably more complex. Consequently, engineers depend heavily on correlations to determine heat transfer in the convection section of fired heaters. The problem related...

Rivers are identified as main sources of plastic litter in oceans. About 65% of the plastic litter is buoyant in fresh waters, meaning it has the capability to float, making transport over rivers relatively easy. A better understanding of how plastic litter is transported via rivers is crucial. Both for quantification and mitigation of the...

Online continuous reinforcement learning has shown promising result in flight control achieving near optimal control within seconds and the capability to adapt to sudden changes in the environment. However no guarantees about safety can be given, needed for use in general aviation. Furthermore performance is often dependent on the precise tuning...

An increase in shipping quantities has put its strain on incumbent integration mechanisms in third-party outbound logistics. Therefore, Application Programming Interfaces (APIs) have recently witnessed increasing attention from practitioners in the logistics industry. However, implementing so-called Shipping APIs has proven to be difficult. With...

For many maritime applications Li-Ion batteries are foreseen as energy storage units that can improve the performance of the on-board power system in terms of continuity of service, fuel consumption, emissions and running hours of main engines. However, one of main limitations of battery application in on-board power systems is the aging of...

Finding a favorable cure for cancer has been one of the main clinical challenges today. Nowadays the majority of the patients is treated with radiotherapy. Recently research in to a new paradigm of radiotherapy, so called FLASH radiotherapy, has opened up a new insight in to reducing negative side effects. FLASH dose rates (>40 Gy/s) have the...

Recently the interest in hydrofoil vessels using a fully submerged hydrofoil increased. Hydrofoil vessels experience a resistance hump and possible instabilities during their takeoff of which both are influence by waves. In order to determine the required power during the takeoff to overcome the resistance hump and to investigate whether the...

Horizontal Axis Wind Turbines (HAWTs) are a very popular source of renewable energy, but these machines are often subject to off-design conditions owing to the unsteady nature of wind. Unsteady aerodynamic conditions have been associated with cyclic loading of turbine blades, which can have hugely detrimental effects on their operational life....

Stick-slip friction is the resulting effect of the transition between the dynamic and static friction coefficient. This effect determines the minimal sustained speed and minimal incremental motion of a movement system, limiting the performance in precise positioning systems. Available bearing types without stick-slip suffer from complexity, high...

The amount of air traffic worldwide is increasing, with an adverse effect on aircraft noise in the vicinity of airports as a result. Measurements and calculations have complementary benefits and limitations for the assessment of aircraft noise. A common method for the calculation of aircraft noise is ECAC Doc. 29. Various improvements of this...

The aim of this thesis project is to investigate the temporal changes of vegetation in Europe using statistical analysis and machine learning. A methodology is used consisting of five main steps. The first is data pre-processing, which is used to reduce the noise within the data set. This is followed by classification, which divides the data...

Coating deposition by Physical Vapour Deposition (PVD) on high strength steels is an important research project at TATA Steel - IJmuiden. The research is aimed at replacing the conventional hot-dip galvanisation process to obtain a defect-free coating without affecting their well-engineered properties. However, the annealing treatment of the...

Waterschap Brabantse Delta (WBD) has the intention to implement measures that enhance the baseflow. Baseflow consists of the groundwater flow and a small part of the interflow. During dry periods, streams are dependent on the baseflow. Enhancing the baseflow has a proper effect on the ecologically relevant quality of waters, and is therefore...
