Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

With tomography it is possible to reconstruct the interior of an object without destroying.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

How can we quantify the density of species within a community through environmental DNA concentrations?

Researchers from the Leiden Institute of Chemistry show proof of principle that live-cell structural changes and metabolic processes can be followed in real time with NMR spectroscopy. They performed their study on photosynthetic green algae that are metabolically flexible and can sustain energy generation…

In order to optimize treatment, it is necessary to closely monitor and manage the patient’s health status by means of ‘precision diagnostics and targeted therapy’. The specialisation combines the techniques and applications of these sensing (monitoring) and stimulation techniques. The field of sensing…

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Can a virtual character’s friendly non-verbal responses stimulate eye-contact in individuals with varying levels of social anxiety?

In the field of Western art music, improvisation has become a much discussed topic. In this interdisciplinary study I argue that in this context, improvisation is not to be seen as a quasi-autonomous skill or art form, but as an aspect of music-making in general.
