NMI – Calibration of Pressure Measurement
In pressure measurement, the value of pressure is determined by dividing the force exerted on a piston by the effective area of the piston. The effective area of the piston may differ from the actual area because of irregularities at the piston edge and because of leakage through the thin cavity between the piston andView problem details

Nucletron – Radiological Needlework
Nucletron is a high-tech, international company, that specializes in equipment for medical diagnostics. Problem description To treat prostate cancer with radiological techniques, the prostate is perforated with a number of needles. Before the radiological treatment may start, the exact positions of these needles must be known. To detect these positions, an ultra-sound sensor is used.View problem details
DSM – Catching Gas with Droplets
At DSM one is interested in the development of packaging materials that are not or little permeable for certain gases. Think of the packaging of meat in a polymer sheet, that should keep the meat free from oxygen. The idea to realize this is to include in the sheet of packaging material droplets that absorbView problem details
