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 …

During this research project the influence of selenium enriched growing environment on the phenolic composition on several Allium species is studied. Besides this, the influence on morphological properties is also monitored. Folin-Ciocalteu method is used to determine the total phenolic content and High …

A decade ago many gushed at the possibilities of 3D printers and other DIY tech. Today makers are increasingly shaking off their initial blind enthusiasm to numerically control everything, rediscovering an interest in sociocultural histories and futures and waking up to the environmental and economic …

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 …

Traditional IMU based PDR systems suffer from rapidly growing drift effects due to the inherent bias of the inertial sensor. Many existing solutions to mitigate this problem use aiding sensors or information as heuristics or map data. We propose a new optimization framework to solve the PDR estimation problem …

Electromagnetic articulography (EMA) is one of the instrumental phonetic research methods used for recording and assessing articulatory movements. Usually, articulographic data are analysed together with standard audio recordings. This paper, however, demonstrates how coupling the articulograph with …

Industrial Design Engineering [Open] Innovation (IDE) is a 3-year, English taught, VWO entry-level, undergraduate programme at The Hague University of Applied Sciences (THUAS). The IDE curriculum focuses on the fuzzy front end of (open) innovation, sustainable development, and impact in the implementation …

In our time, professions are passed on form father to child less and less, and some professions related to craftsmanship are disappearing, being replaced by industrial production. I come from a family of wooden artisan, and I witness what happened to my grandfather when he could not work anymore: deprived …

Introduction: This prospective study aimed to study the composition and structure of the vaginal microbiota prior to Chlamydia trachomatis infection. Methods: A nested case-control study was performed in 122 women, half of which acquired C. trachomatis within a year after their first visit. At the first …
