The Brains4Buildings project aims to develop methods to design new smart building climate management systems that, among other things, reduce energy consumption, increase comfort and respond flexibly to user behavior. We set out to develop design guidelines to help B4B stakeholders when designing innovative …

Lichtvervuiling is mogelijk een van de oorzaken van de afname van de motten populaties. Eerder onderzoek op motten heeft al negatieve effecten aangetoond. Licht met lange golflengten heeft vaak een significant kleiner negatief effect dan licht met korte golflengten. Deze onderzoeken zijn niet uitgevoerd …

Calibration of spectral imaging instruments is a prerequisite for many applications, in particular in the field of Earth observation. In this contribution we will present a novel traceability route to celebrate spectral imaging instruments, based on tunable radiance source that is referenced to a primary …

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 …

The use of wireless acoustic sensor networks (WASNs) has received increased attention over the last decade. The advantages of WASNs over stand-alone multi-microphone devices are that the microphone array is not anymore limited by the dimensions of a single device, and that microphones can be placed at …

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 …

Climate change accentuates heat waves in The Netherlands. This, in combination with high nutrient concentrations in Dutch surface waters, is intensifying the proliferation of toxic blue-green algae (cyanobacteria), a threat for the health of the population and ecosystems. Lakes are resources for recreational …

Improved remote sensing in the field of UAV (Unmanned Air Vehicle) and SFM (Structure From Motion) photography provides the potential for efficient access to forest inventory parameters. These parameters help identify the forest structure, calculate carbon stocks, support sustainable timber extraction …

SRON is the Dutch national expertise institute for scientific space research and is part of NWO. It plays an important role in delivering contributions to the national and international space-research communities. Currently one of SRON’s involvements is in the X-IFU instrument for the Athena space X-ray …

Using the reversed phase high performance liquid chromatography with diode-array and massspectrometric (in ESI mode) detection, a composition of Catharanthus roseum petals was established. After the acid hydrolysis, all five anthocyanidins were found to be different comparing to the ordinary anthocyanidins …
