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:...

Cost overruns in infrastructure projects has been a well-known phenomenon for almost a decade. As per the generally accepted definition, the industry has been measuring cost overruns as the cost exceedance with respect to the approved contractor’s budget. But researchers are realizing the fact that the decision-to-build is generally taken long...

The goal of this study was to investigate whether mobile C-arms are being optimally used, securing the safety of staff members in operating rooms of the Reinier de Graaf hospital (RDGG). Mobile C-arm use is evaluated in terms of radiation emission and radiation exposure, staff communication and procedural aspects. The current use of the mobile C...

Statistics show that cycling accidents have the biggest (and increasing) contribution to the overall number of hospital visits related to traffic accidents in the Netherlands. In the majority of these cycling accidents, no other road users are involved. Because the majority of the cycling accidents are so-called single vehicle accidents,...

The significant impact of airborne cabin pressurisation and cooling systems on fuel consumption requires new technologies to be investigated. In the pursuit of decreasing fuel consumption while leveraging on the benefits of electrification, a shift was initiated from conventional bleed air driven to electric powered air cycle machines based...

Intimacy is important for every human being. It contributes to our social contacts, physical health and quality of life. Intimacy also plays an important role in the lives of elderly, despite certain prejudices. Nevertheless, there is often a lack of attention for intimacy in elderly care. This graduation project therefore aims to give intimacy...

Human exploration on Mars is nearing actualisation and the space industry is therefore in need of vehicles with the capability of transporting goods and exploring the surrounding area. Current Mars rovers by NASA, such as the Curiosity, provide excellent researching capabilities from a remote location. <br/><br/>However, these land based drones...

The control of a dedicated ITT system operating human driven MTSs and AGVs can be centralized, decentralized or distributed. The objective of this research is to find which controller structure is best suited for controlling a mixed traffic ITT system. In doing so, performance differences will be reviewed to gain insight into the effect of...

Silicon heterojunction solar cells employing transition metal oxides as carrier selective contact are of particular interest due to the potential of reducing parasitic absorption while featuring optimal electrical properties. Recently, a record efficiency of 23.5% was achieved by employing molybdenum oxide (MoOx) as carrier selective contact....

Computers are preferred above humans when dealing with information processing because of the great memory and fast computing times. The use of algorithms within complex planning processes is an interesting research field. These algorithms should help human planners with the planning process and therefore are called Planning Assistance Tools (PAT...

In this master thesis the current Dutch method of combining failure probabilities at different spatial scales is researched. This method is used in the Dutch flood risk analysis of earthen dikes to assess the probability of flooding. Currently, probabilities of flooding for geotechnical failure mechanisms are obtained which are not considered to...

The advent of miniaturized satellites has sparked an interest in effective methods of exploiting their capabilities. Potential has been found in propulsion­enabled units, and TU Delft is at the forefront of researching and developing suitable propulsion modules for thrust generation or attitude control of small satellites classified as Cubesats...

This research applied a Dual Extended Kalman Filter (DEKF) to time-varying human operator (HO) parameter estimation in preview tracking tasks. The preview time parameter was of particular interest, as the amount of preview can be highly variable in practical situations. The filter was centered around a linear cybernetic HO model with six...

An experimental investigation was done regarding the propulsion system and airframe integration issues associated with the novel Flying V configuration. The experimental investigations involved a series of wind tunnel tests with a 4.6% scale half model, conducted in the TU Delft OJF low speed wind tunnel. Balance measurements allowed significant...

Pretreatment and densification processes such as torrefaction coupled with pelletization have proven to be valuable techniques to convert biomass to solid biofuels. Presently, waste streams from the torrefaction process in the form of volatiles are usually combusted to generate heat required for the torrefaction process. Nevertheless, the...

The goal of this research was to perform a 3D end-to-end test on a MR-linac to check the whole workflow using a clinical treatment plan. Dosimetric gel was used to obtain 3D spatial information, with the phantom in the same position for irradiation and scanning. In order to achieve this, fundamental elements of gel dosimetry needed to be...

In this thesis, a new method to approximate the cost function of Low-Thrust, Multiple-Gravity-Assist interplanetary trajectories using a Machine Learning surrogate is proposed. This method speeds up the optimization process without fine tuning of the surrogate parameters for every individual case. The computational cost of obtaining training...
