We have developed an SI-traceable narrow-band tunable radiance source based on an optical parametric oscillator (OPO) and an integrating sphere for the calibration of spectroradiometers. The source is calibrated with a reference detector over the ultraviolet/visible spectral range with an uncertainty …

Many people on Earth are hungry or do not have a reliable source of drinking water. Drought-tolerantcrops do not need much water to grow and therefor usable in regions where water is an issue. Cropbreeders are working on crops that are more drought-tolerant and grow faster. Corp …

The main research question of this project was:Which of the four chosen algae is the most suitable for the rearing of Artemia, and ultimately Diadema antillarum larvae, at Van Hall Larenstein University of applied sciences? This question led to several sub questions which could in turn be operationalized …

This paper describes a calibration method for inertial and magnetic sensors using a batched optimization procedure. Well estab- lished sensor, motion and constraint models are applied which include sensor gains, biases, misalignments and inter-triad misalignments. For the magnetometer, hard and soft …

Within this research a smart textile based light sensor was developed and integrated into a technical demonstrator of a remote identification system. This sensor is based on polymeric optical fibers (POFs) which contain fluorescent dopants and allows a remote detection using an optical laser pulse for …

Saybolt is a petrochemical company that invest in different types of oils and fuels. Saybolt Vlaardingen has purchased a new Perkin Elmer Optima 8300 ICP-OES (Inductively coupled plasma optical-emission spectrometry) that must be validated. The ICP-OES is used to analyze metals in petroleum products. This …

The number of people suffering from chronic wounds is developing into a seriousmedical problem causing high burden on patients, healthcare system and the societyas a whole. Patients suffering from the diseases are severely impaired in theirquality of life and the treatment measures create high costs …

This paper describes the concept of a new algorithm to control an Unmanned Aerial System (UAS) for accurate autonomous indoor flight. Inside a greenhouse, Global Positioning System (GPS) signals are not reliable and not accurate enough. As an alternative, Ultra Wide Band (UWB) is used for localization. The …

To better control the growing process of horticulture plants greenhouse growers need an automated way to efficiently and effectively find where diseases are spreading. The HiPerGreen project has done research in using an autonomous quadcopter for this scouting. In order for the quadcopter to be able …
