Samenvatting Inleiding: Alhoewel er al veel geschreven is over het opstaan van ouderen, gaat dit vooral over de biomechanica en sta-op strategieën. Echter weinig is er nog bekent over het effect van een sta-op stoel op de fysieke activiteit van ouderen, terwijl voldoende fysieke activiteit essentieel …

A new gravitation wave observatory is being built in Japan. This facility is a big Michelson interferometer where the mirrors and sensors will be made cryogenic down to 4 K. The problem is that: the heat cannot be transported out of the mirror by its surroundings because the whole system is in an ultra-high …

The treatment of tumours in cancer patients have become more advanced and thus more complex. The verification of the dose distribution, calculated by clinical physicists, have thus become more complicated. VSL has started the development on measurements of absolute dose distributions in an antrhopomorphic …

A laboratory test setup is built to transfer and actively stabilize an ultrastable signal, obtained from a laser with sub-Hz linewidth, trough a 5 km long fiber link. The fiber noise is measured and compensated via a feedback loop acting on an AOM that can change the frequency (and therefore the phase) …

Nuclear fusion is seen as one of the future technologies for roducing electrical power. In a hot and con ned plasma deuterium and tritium will melt together and form a helium nucleus and a neutron. This process produces a total of 17.6 MeV energy. In the plasma instabilities occur. Suppression of these …

The recently developed HyperCollar applicator was specifically designed to heat tumors in the head and neck region. The applicator uses twelve antennas to create an EM interference pattern, which applies heat to the target area. Patients' position and movement needs to be tightly monitored and controlled …

In this report the properties of the E-field sheet have been measured. Also the connection between the E-field sheet and the pc has been developed. For visualisation of the data a GUI has been made in Matlab which also reads out the data from the DAQ card. Before a measurement on the clinical equipment …

The Pierre Auger group is studying ultra-high energy cosmic rays. Cosmic rays are charged particles which permanently hit and penetrate the atmosphere of the Earth. They will at a certain moment collide with nuclei in the atmosphere, like nitrogen. The results of such an interaction are new particles, …

The starterstraject is a project set up by the Chamber of Commerce and the city of Zoetermeer. The goal of the starterstraject is to give the starting entrepreneur a head start. The starting entrepreneur is prepared for the risks and difficulties that arise when starting a new business. The starting …

Laboratory research was done on flat glass substrates to study the effect that brine salinity has on adhesion mechanisms between oil and clay particles. This is done by evaporating a small clay suspension droplet (6 ul) on a glass slide that leaves a thin layer of clay upon which oil can be attached. …
