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, …

Single Fiber Reflectance spectroscopy (SFR) can be used to determine tissue optical properties such as scattering and absorption. The SFR technique employs a semi-empirical modal, which contains a parameter that is dependent on the fiber numerical aperture, NA . However, the NA is a wavelength dependent …

A greenhouse with Fresnel lenses in the south facing roof and a receiver for concentrated Photovoltaics with water cooling (CPVT system) will result in electrical and thermal energy output from the solar energy excess entering a greenhouse. The PV system converts about half of the direct radiation into …

In this article we investigate the change in wetting behavior of inkjet printed materials on either hydrophilic or hydrophobic plasma treated patterns, to determine the minimum obtainable track width using selective patterned μPlasma printing. For Hexamethyl-Disiloxane (HMDSO)/N2 plasma, a decrease in …

Inkjet printing is a rapidly growing technology for depositing functional materials in the production of organic electronics. Challenges lie among others in the printing of high resolution patterns with high aspect ratio of functional materials to obtain the needed functionality like e.g. conductivity. …

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. …

Engagement is seen as an important characteristic of action research. The term is often used to refer to the participation and involvement of the research participants. Within this article we take another angle and explore the concept of engagement in relation to the main action researcher. Using an …

Work related learning is a topic of considerable interest currently and can be broadly seen to be concerned with all forms of training and learning closely related to the daily work of employees. From the angle of higher education work related learning is an important development because parts of the …

How and where can Dutch design entrepreneurs find work in Germany? This was the question DutchDFA put to the research team at Inholland University of Applied Sciences in February 2010. But the researchers took a different angle, and generated unexpected data, revealing patterns, and valuable new insights …

The design and realization of a healthy indoor environment is a challenge that is investigated from different perspectives at the unit Building Physics and Systems (BPS; Faculty of Architecture, Building and Planning) of Eindhoven University of Technology. Performance requirements (for instance, with …
