This thesis studies the radiation dose deposited on a 6U CubeSat in interplanetary orbit. The European Space Agency’s radiation data tool SPENVIS has been used to determine the proton flux in interplanetary space during a solar particle event which occurs only once every one hundred years. SPENVIS has further been applied to obtain a dose depth...

In-space manufacturing proves more important now than ever. The capability of creating a sustainable manufacturing strategy for spare parts or tools would significantly improve both mass budget and costs. Therefore, additive manufacturing (3D printing) in space is seen as an enabler of future scenarios that explore beyond the current boundaries...

The static stability of stones on mild slopes under wave attack is investigated in this research. The first part of the research is focused on reproducing the physical scale model tests regarding profile change of Kramer (2016) numerically with the model XBeach-G. The erosion profiles modelled with the bed-load transport formulas of Nielsen ...

Spacecraft are under constant threat of structural damage from hypervelocity impacts by micrometeoroids and orbital debris. To bolster the shielding used for protection against these impacts, ballistic materials can be employed. Aramid-based materials are currently used aboard the International Space Station (ISS), but Ultra High Molecular...

The load of the electric grid in increased by the connection of more renewable energy sources and less controlled power stations. The transmission operator has to decide where and when new overhead lines are required. However the operator can also chose to utilize existing lines more by increasing the transport capacity. This can be accomplished...

In the last decades induced earthquakes are taking place more frequently in Groningen. This is due to gas extraction form the soil. Buildings are damaged by the earthquakes and building collapse is possible in the near future. Houses in Groningen are commonly build up out of single leaf masonry cavity walls and are not designed for earthquake...

The amount of air traffic is increasing and cities become more and more populated. Since airports tend to be located close to or inside cities, an increasing amount of people suffer from aircraft noise pollution. More silent aircraft are needed to be able to reduce this noise pollution. One way to do this is through blocking the engine noise...

MARIN has developed the computer program WINDOS for the calculation of wind loads on vessels and various offshore structures. To account forwind shielding effects,semi-empirical relations based on Schlichting’stheory for free turbulent flow are used within the program.An extensive WINDOS investigation is carried out in comparison with the wind...

For the design of granular bed protections often a stability parameter is used. The stability parameter represents the forces that are acting on the stones and is used to predict the response of the bed to these forces. Existing parameters are often derived for a limited range of application. When the parameter is used outside this range, the...

This thesis has as subject the shielding effect of piles on the front wall of quay walls. The reason for writing this paper is to find an answer to the difference between field measurements and design calculations of stresses and deflections in the front wall of a special type of quay wall in the Port of Rotterdam. The relevance of this issue...

The Maasvlakte II project is a joint venture between Boskalis and Van Oord. During the construction, they have measured the relative density for different kind of work methods, by making cone penetration tests. The result of those measurement is, that the measured relative density for the Maasvlakte II project is higher than the values that can...

The report is the result of the graduation assignment titled “Optimizing the functional and ergonomic properties of a conceptual bullet resistant police shield” and is the final part of the TU Delft’s MSc Programme Design for Interaction. A conceptual shield designed by van Someren was the basis for this project. By analyzing the market and the...

Voor de berekening van de stabiliteit van stenen moet een beschouwing worden gemaakt van de krachten welke werken op een steen in een stroming. Deze krachten zijn natuurlijk ten eerste het gewicht van de steen onder water en verder de kracht welke de stroming op de steen uitoefent. 1) De krachten door het water zijn evenredig met het kwadraat...

Vloeistofmechanica van de TU Delft. De experimenten zijn uitgevoerd onder gelijke condities als bij de onderzoeken van Paintal (1969) en De Boer (1998). Bij de onderzoeken is dezelfde bodemopbouw, hetzelfde bodemmateriaal en dezelfde aanleg van het testbed gebruikt. De meettechnieken waren bij de onderzoeken verschillend, maar hadden als...

Experimenteel onderzoek naar de validiteit van een sediment pick-up functie. Sinds 1988 is door Bakker en Van Kesteren gerapporteerd over de ontwikkeling van een sediment pick-up theorie. De theorie beschrijft erosie van horizontale zandlagen onder invloed van hoge stroomsnelheden. Uit de theorie is op analytische wijze een sediment pick-up...

Voor de aanleg van tunnels bieden boormethoden steeds grotere voordelen. In Nederlandse grond zal veelal slechts geboord kunnen worden gebruik makend van een schildmethode, in de meeste gevallen gecombineerd met boorfrontondersteuning. Het schild waarborgd de stabiliteit van de grond in radiale richting. Door middel van boorfrontondersteuning...

De fascinatie voor de ondergrondse ruimte heeft reeds menigeen geïnspireerd tot het verrichten van onderzoeken of praktijkproeven en het schrijven van artikelen of boekwerken. Deze scriptie haakt in op een eerder uitgevoerd onderzoek door A.E.A. de Groot, getiteld "Afweging voor het gebruik van het slurry- of EPB-schild". In dat onderzoek heeft...
