On a mountain in Chile's Atacama desert the world's largest optical telescope is currently under construction: the Extremely Large Telescope (ELT). The ELT's primary mirror has a diameter measuring 39 meters and consists of almost 800 segments, each of which is operated using three position actuators. PhD candidate Arjo Bos designed actuators that satisfy the extreme requirements of this giant telescope.
ProRail outsources the maintenance of the Dutch rail network to a number of large contractors, each responsible for their own region. PhD candidate Loe Schlicher proved that it is cheaper to have these maintenance companies share machines and spare parts. “This enables all parties to save money, but as yet they are very reluctant to enter into cooperative relations.”
Their names are uninspiring, but 14-3-3 proteins occur in all our body's cells, where they fulfill countless vital functions. PhD candidate Loes Stevers found a way to help 14-3-3 proteins function even better, and in so doing may have laid the basis for medicines that combat cystic fibrosis and Parkinson's disease.
After a gastric reduction, severely overweight patients do not only lose weight fast, gradually they are also affected less by additional disorders such as high blood pressure and cholesterol, diabetes and sleep apnea. Graduating student Ruben Deneer used data from Catharina Hospital to develop the Metabolic Health Index: a measure for the extent to which patients still suffer from these so-called comorbidities.
While you cannot see infrared light, this invisible component of the sunlight can have a great impact on the indoor temperature. For this reason the Indian PhD candidate Hitesh Khandelwal made window panes that allow infrared light to pass through when it is cold, and to reflect it under warm conditions. These ‘smart windows’ can help save heating and air conditioning costs alike.
Hydrogen is a raw material that is used widely in the chemical industry and is also regarded as an important energy carrier for a sustainable future. However, present-day production methods of hydrogen consume a lot of energy, and its transportation is also anything but efficient. For this reason PhD candidate Arash Helmi from Iran has been working on a membrane reactor which makes it possible to produce very pure hydrogen locally on a small scale.
By controlling the rotational speed of each wheel separately, the new electric race car of University Racing Eindhoven (URE) must become faster than its predecessors. Master’s student Automotive Martijn van der Drift graduated on this new control strategy.
