Falling is a significant problem for older adults. It can cause severe injury and even death. Furthermore, the fear of falling has a significant influence on the life of the elderly, and therefore they reduce their physical activity. Two new balance assistive devices are being developed to reduce the risk of falling. Both devices use a control...

Parcel deliveries have seen a massive grow over the past several years, mainly in the B2C sector due to rise of online shopping. Due to this growing market more transport movements in the last mile are required. These extra driven kilometers add up to an increase in Greenhouse Gas (GHG) emissions. In a world where the ask for more sustainable...

Indirect adaptive control for the Innovative Control Effectors (ICE) aircraft requires an online aerodynamic model identification strategy to re-estimate the aerodynamic coefficients. Simplotope B-splines in combination with distributed optimization enables for local updates in a global aerodynamic model. This combination reduces the estimation...

A big part of the schools in Greece fails to align with the regulations suggested by The School Building Organization in Greece, regarding their energy performance as well as the thermal and daylight comfort they offer. This study aims to inform the retrofit process of these schools, by proposing guidelines concerning the most impactful...

Mixed Integer Linear Programming (MILP) is a generalization of classical linear programming where we restrict some (or all) variables to take integer values. Numerous real-world problems can be modeled as MILPs, such as production planning, scheduling, network design optimization and many more. MILPs are, in fact, NP-hard. State-of-the-art...

Machine learning has been a computer sciences buzzword for years. The technology has a lot of potential and a huge number of applications that spoke to people with and without knowledge of computer sciences. Image, text and speech recognition, social profiling, computergames, everything seemed possible. Machine learning is not as much in the...

Viscoelasticity is a material property that is relevant in a variety of nanoscale materials and interfaces in medicine and industry. Therefore, a method of mechanical quantification has become exceedingly desired. In this thesis the Atomic force microscope (AFM) is applied to accurately characterize the mechanical behavior of viscoelastic...

The goal of this thesis is to identify under which boundary conditions<br/>there is a business opportunity for an innovative electric thermal energy storage, with regards to the future electricity and heat markets. To meet this target, a novel optimization model has been developed as the main tool for the analysis of the storage and its...

We study the problem of finding a temporal hybridization network for a set of phylogenetic trees that minimizes the number of reticulations. First, we introduce an FPT algorithm for this problem on an arbitrary set of t binary trees with n leaves each with a running time of O(5^k*n*m) where k is the minimum temporal hybridization number. We also...

Quantum coin flipping is a cryptographic primitive in which two or more parties that do not trust each other want establish a fair coin flip. These parties are not physically near each other and use quantum communication channels to interact. A quality of protocols is measured by the best possible cheating strategy, which is the solution of a...

In the past decade, the wind energy subsidies provided by the Dutch government is declining. In order to adopt wind energy as a well-established source of renewable energy, the costs of (offshore) wind energy should be lowered. This can be achieved by increasing the energy production or by lowering the maintenance and initial costs. In search of...

Many users of body-powered upper extremity prostheses experience difficulties using their device and a large group abandons usage altogether. Shoulder control via Bowden cable is widely used because of the intuitive use and low cost, but requires large shoulder movements and high operating forces that, according to literature, often exceed the...

Our present-day society is utterly dependant on electricity. This dependence will only grow as electrification of sectors such as manufacturing, transportation and building heating takes off. Most of the electricity these days comes from conventional plants running on coal and natural gas. Despite that these are reliable and cheap, the...

The propellantless nature of solar-sail propulsion allows researchers to design completely new sets of orbits unreachable or not-maintainable by means of conventional propulsion. The advantage of this somewhat new type of low-thrust propulsion system becomes more evident for long-duration missions where chemical or electrical rocket engines...

Water is an important resource in many industries in the world. Due to emerging regulatory framework, change in consumer’s perspective and increasing costs for water, industries are forced to move towards sustainable water use. Nowadays, improvements in the brewery industry are focussed on increasing the efficiency of the processes or treating...

When considering techniques for producing the Pareto front of a <i>Multi-Objective Optimization Problem</i> (MOOP), there exists a trade-off between the effectiveness of the method in obtaining the Pareto front and the computational cost required to achieve that. For a method to be effective, the generated solutions must result in a true...

This thesis project achieves designing and comparing two parallel implementations for exhaustive grid search along a large model space to find the optimum mapping model for overlay predictions used in ASML lithography machines. The search algorithm leads to an effectively intractable problem as long as sequential implementation is concerned, but...

The operating room and central sterile supply department (CSSD) are two<br/>resource-intensive healthcare departments. Reducing the environmental and financial impact of these departments is of great importance in the global debate on sustainability. Removing unnecessary items from instrument trays may provide a partial solution. However,...

The goal of this research is to optimize the fiber layup of a carbon windsurfing boom for weight and stiffness. A windsurfing boom should be stiff to provide an efficient basis for the energy transfer from the sail through the surfer to the board. The weight of the boom is important as the total weight of the rig influences the performance,...
