Aquifer thermal energy storage (ATES) is a technology with worldwide potential to provide sustainable space heating and cooling using groundwater stored at different temperatures. In areas with high ambient groundwater flow velocity (>25 m/y) thermal energy losses by displacement of groundwater may be prevented by application of multiple...

This thesis focuses on the coagulation and flocculation processes of cohesive sediments under the influence of polyelectrolyte. For this study clay particles and anionic and cationic flocculants were used. The influence of the shear stresses on the flocculation demonstrated that the shear stress is the parameter that influences the most the...

Robotic systems are the workhorses in practically all automated applications. Manufacturing industries, warehouses, elderly care, disaster rescue and (unfortunately) warfare are example applications where human life has benefited from robotics. By precisely planning controlling their motions via computer programs, real world tasks can be...

HoW do you look inside a box without opening it? How can we know whether or not a heart valve is functioning correctly without cutting a person open? Imaging – the art of seeing the unseeable. A CT-scan at the doctor’s office, crack detection in the wing of an airplane, and medical ultrasound are all examples of imaging techniques that allow us...

Sewer systems are underground infrastructure networks, comprising pipes, manholes and ancillary works, that collect and transport rainfall runoff and sewage to wastewater treatment plants. These systems protect society from exposure to faecal contamination and flooding of urban areas due to heavy storm events to a predefined service level....

Embedded systems range from very simple devices, such as a digital watch, to highly complex systems such as smartphones. In these complex devices, an increasing number of applications need to be executed on a computing platform. Moreover, the number of applications (or programs) usually exceeds the number of processors found on such platforms....

The electrical power grid is a fundamental infrastructure in today’s society. The synchronization of the frequency to nominal frequency over all the network is essential for the proper functioning of the power grid. The current transition to a more distributed generation by weather dependent renewable power sources, which are inherently more...

Physics at the level of an atom is dominated by laws of quantum mechanics. Often, this is entangled with a high complexity in behavior of the systems at that length scale. Unravelling the properties of a material at the atomic level is, therefore, a challenging task that easily supersedes current computational capabilities. A route to circumvent...

In this thesis, we have investigated the optoelectronic properties of metal halide perovskites with a special focus on their application in solar cells. In less than a decade of development, metal halide perovskites have yielded solar cells with efficiencies comparable to commercialized technologies. However, there has been limited knowledge...

Outbreaks of bacteria have caused many problems over the last few years and are a major public health concern. Bacteria are now affecting our lives in many ways to a more severe extent, from contaminated food in markets to polluted water. There are some devices available which detect bacteria, however, all of them can only be used in the lab...

The liquefaction flow slide is an important failure mechanism for under water slopes composed of sand.

The failure of the sand body is the result of liquefaction of loosely packed sand, which suddenly looses a large part of its strength and starts behaving as a fluid. Liquefaction flow slides occur unexpectedly and develop at a very...

Artificial sand nourishments are a common measure to mitigate coastal erosion problems. Such nourishments can have an impact on currents and waves near the beach, especially when the nourishment has a large size. As nourished beaches often have a recreational function, these altered wave and current patterns may pose a threat to swimmers. This...

Kapsenberg, G.K. (author)
Slamming of ships is a phenomenon characterized by a high wave load of short duration. Usually the ships structure responds in a vibratory manner on this load; the response can be either a local or a global vibration mode or it can be in both modes together. These short duration loads are caused by large amplitude motions, even to the point that...

This dissertation builds upon research that considers how cities operate as Complex Adaptive Systems (CAS). It focuses on how certain characteristics of urban form can support an urban environment's capacity to self-organize, enabling emergent features to appear that, while unplanned, remain highly functional. The main thrust of the work is to...

Offshore wind generated electricity is currently one of the most promising sources of energy to contribute in creating a sustainable global energy mix. The latter is essential for minimising the detrimental impact of human-induced accelerated climate change. The cost of offshore wind power has strongly decreased over the past years due to ...

Our civilization is facing one of the biggest challenges in its entire history: the energy transition. The growing demand for energy, the scarcity of resources and climate change are the three main factors driving the change. Firstly, the world population is expected to keep on growing, and many poor countries are projected to experience rapid...

Arterial stiffness is a reliable prognostic parameter for cardiovascular diseases. The effect of change in arterial stiffness can be measured by the change of the pulse wave velocity (PWV). The Complior system is widely used to measure PWV between the carotid and radial arteries by means of piezoelectric clips placed around the neck and the...

Artificial intelligence, and in particular machine learning, is concerned with teaching computer systems to perform tasks. Tasks such as autonomous driving, recognizing tumors in medical images, or detecting suspicious packages in airports. Such systems learn by observing examples, i.e. data, and forming a mathematical description of what types...

Dynamical systems theory can significantly contribute to the understanding and control of fluid flows. Fluid dynamical systems are governed by the Navier-Stokes equations, which are continuous in both time and space, resulting in a state space of infinite dimension. To incorporate tools from systems theory it has become common practise to...

Spectroscopy is a powerful tool to investigate the physical properties of complex systems. The interaction of light with matter allows to get insights into the structure of it. Chapter 1 is dedicated to introduce this topic and to show the developments of the technologies that paved the way to its success. Special focus is given to the...
