TU Delft has started working on its third satellite mission called DelFFi, which is planned for a launch in 2015. In this graduation project spanning 17 weeks, a faulttolerant storage system consisting of three SD cards was designed, implemented and tested for DelFFi that utilizes triple-modular redundancy …

The effect of an elevated sample temperature on the growth rate of carbon in the holes of a Multiple Aperture Array (MAA) has been examined. The loss of transmitted electrons through the MAA was measured by taking pictures with a camera of an Yttrium Aluminum Garnet (YAG) scintillation crystal. The growth …

Kipp & Zonen, based in Delft manufactures and develops atmospheric measurement instruments, including a scintillometer. Kipp & Zonen currently manufactures the large aperture scintillometer (LAS) MkII and previously manufactured the extra large aperture scintillometer (XLAS) MkI. A scintillometer can …

PURPOSE: Advanced radiotherapy treatments require appropriate quality assurance (QA) to verify 3D dose distributions. Moreover, increase in patient numbers demand efficient QA-methods. In this study, a time efficient method that combines model-based QA and measurement-based QA was developed; i.e., the …

Abstract-Architecture Compliance Checking (ACC) is an approach to verify the conformance of implemented program code to high-level models of architectural design. ACC is used to prevent architectural erosion during the development and evolution of a software system. Static ACC, based on static software …

Abstract-Architecture Compliance Checking (ACC) is useful to bridge the gap between architecture and implementation. ACC is an approach to verify conformance of implemented program code to high-level models of architectural design. Static ACC focuses on the modular software architecture and on the existence …

Research is done on the properties of a niobium superconducting magnetic shield sample (see image below this abstract), its magnetic attenuation; and behaviour around the transition temperature 9.25 K. The attenuation of the magnetic shield sample was measured in a cryogenic setup. This is required to …

Off the coast of Mauritius there is a small islet of just 7 hectares, covered in coral reef, named Ile aux Aigrettes. this islet is maintened by the Mauritian Wildlife Faundation and opened to the public to show the natural heritage of Mauritius. Many species living in Mauritius cannot be found anywhere …

Piracy and DRM are both forces that impact negatively as well as positively on the video game industry. Attempting to work these two forces together is difficult, if not impossible. Piracy cannot be stopped, and DRM cannot work its way around piracy in any way. This paper attempts to find a way to connect …

The Electronic Portal Image Device (EPID) is only used to verify the patient's position during treatment, but the EPID has much more potential than just position verification. The EPID can be used for multiple purposes and therefore MAASTRO clinic is developing their own software. Matlab is the most …
