Students, researchers, professors and company representatives gathered to share progress and ideas at the second half-year symposium of HiPerGreen at the World Horti Center in Naaldwijk. HiPerGreen is a Raak MKB subsidised research project aiming to bring value to horticultural growers. Cock Heemskerk, …

A detailed solar prediction is necessary in case of particular cloudiness-patterns causing undesirable large fluctuations in photovoltaic electricity production. By considering the project objectives and expected outcomes, as well as the fact that the motion of the clouds is the key element that influences …

The airport of Mexico City is suffering from congestion problems during part of the day. For that reason the government announced the construction of a complete new one which is supposed to be operative in 2020 in its first phase. However the economic downturn in the country jeopardize the complete project …

Bij onderzoek naar ecologie en waterkwaliteit kunnen onderwaterdrones worden toegepast. De drones, uitgerust met diverse sensoren en camera’s, blijken een waardevolle toevoeging aan de reguliere steekmonsters die de ecologische kwaliteit van het waterlichaam beoordelen. Uit de eerste resultaten blijkt …

In this thesis the workings of a time-resolved setup are treated as well as the underlying physics. The setup is based on optical gating, which gives control over very short moments in time to let light pass through a gate. As this process is stable, light can be studied in very short and low intensities. …

A program that automatically detects auroral events in all-sky images taken by the all-sky camera of IRF has been written. Current programs that automatically detect the aurora in all-sky images using the RGB color system often miss strong aurora and sometimes interprets clouds as aurora. To improve …
