The European Union and the United States are proposing to bring in more strict flight vehicle emission criteria in their reports of the high‐level groups on aviation research, i.e. EU Flightpath 2050 and US Destination 2025. More fuel‐efficient aircraft must be developed to achieve this target. Moreover, the increasingly competitive aviation...

The aim of Transmission Expansion Planning (TEP) studies is to decide which, where, and when new grid elements should be built in order to minimize the total system cost. The lumpiness of the investment decisions, together with the large size of the problem, make the problem very hard to solve. Consequently, methods should be put in place to...

Developing intelligent decision making systems in the real world requires planning algorithms which are able to deal with sources of uncertainty and constraints. An example can be found in smart distribution grids, in which planning can be used to decide when electric vehicles charge their batteries, such that the capacity limits of lines are...

Beamforming is a signal processing technique used in highly directional antennas. An array of antenna elements transmits the same signal, but with a different time delay for each element. By providing the right time delays for each antenna element, the whole array transmits a high-powered signal in one desired direction. This technique can be...

It is hard to imagine a world without bridges. Bridges lie at the heart of our civilization bringing growth and prosperity to our society. It is by virtue of bridges that communities are able to physically connect to new people and to new places that were previously disconnected. However, bridges are more than mere functional assets. A well...

The Newton-Raphson method (N-R) has been widely used in nonlinear FEM analysis of quasi brittle materials, such as masonry, concrete and reinforced and prestressed concrete. However, the robustness of the N-R method is still a serious issue when bifurcation, snap-back or divergence problems arise. In order to enhance the robustness of solving...

With the rising demands from customers and users and the development of ever advanced technologies, many space missions nowadays require more than one satellite to fulfill their mission objectives. Although replacing single satellite systems (SSSs) by multiple satellite systems (MSSs) offers advantages, such as enhanced spatial and temporal...

This study aims at improving the hydrological process understanding of the semi-arid and transboundary Incomati river basin to enable better water management. Comprehensive statistical and trend analysis of rainfall and streamflow were conducted, and the Indicators of Hydrological Alteration tool was deployed to describe the streamflow regime...

Quantum computing promises an exponential speed-up of computation compared to what is nowadays achievable with classical computers. In this way, it enables the evaluation of more complex models and the breaching of current security algorithms. For the operation of a quantum system, many questions remain to be answered. Currently, there are...

Within estuaries one can often observe areas where the concentration of fine suspended sediments is higher than in the surrounding waters, called estuarine turbidity maxima (ETM). ETM play an important role in the natural and socio-economic value of estuaries. The suspended sediments can for example greatly diminish the value of the estuarine...

Covalent reversible chemistries give rise to polymers with reasonable mechanical properties yet require external stimuli to heal. Oppositely, supramolecular systems can heal autonomously, but their properties are still far away from most of those set by application requirements. Both downsides need to be addressed before intrinsic healing...

This Ph.D. dissertation describes the theory and realization of wide-bandwidth magnetic sensors for current measurements which breach the conventional offset and noise constraints in CMOS processes. These are achieved by several circuit-level and system-level innovations, including the use of three orthogonal ripple reduction loops (RRLs) in...

In the 21st century, polar land ice melting became one of the driving factors of global sea level rise, which is discussed widely by the media and the public. Although the fact of the shrinking ice caps and accompanying changes in the sea level is established, the actual amount of polar ice melting still needs to be quantified in separate...

The microtubule cytoskeleton is an intracellular polymer network involved in cell shape, cell motility, and cell division. Microtubules are self-assembling, dynamic polymers composed of tubulin proteins that alternate between phases of growth and shrinkage, a behaviour known as “dynamic instability”. A key feature of microtubules is their...

This thesis presents research on Boundary Layer Ingestion (BLI). BLI is an unconventional aircraft-engine integration technique which aims at integrating the aircraft and the propulsion system such that the overall aircraft fuel consumption can be reduced.
This research begins with a literature survey on propulsion integration. The...

This dissertation concerns transport measurements in single-molecule junctions using the mechanically controlled break junction (MCBJ) technique. It describes various aspects that play a role in charge transport through single molecules, in order to develop the necessary knowledge to ultimately develop electronic devices based on intrinsic...
