Extrudate swell simulations and experiments have been performed with a viscoelastic tire rubber compound at high flow rates through a circular die. A 3-mode PTT model was fitted onto rheological data of the rubber. The PTT model covers the range of shear rates present in the simulation. Convergence of …

From the thesis: SUMMARY Raspberry-like particles were made with spherical positively charged seed particles and spherical negatively charged smaller particles. The attraction from the small particles onto the surface of the seed particles is a heterocoagulation technique. It has been proven that it …

The research sought to assess the impact of Operations Triton, Poseidon and Sophia on migrants seeking asylum in the EU, in terms of the risks associated with their journey and the prospect of finding asylum in the EU. It focussed on the period between 1 January 2015 and 14 September 2016, in which the …

Abstract A setup is designed and constructed to perform specular reectance spectroscopy on an enzymatic reaction, while simultaneously monitoring the heat produced by the reaction using a FLIR camera. The spectrum of ethanol was recorded using two MCT detectors and showed clear overlap with literature …

Before the start and during the first weeks of their first year, it has been observed by teachers that engineering students start with a high level of motivation, which often seems to decrease during the course of the first semesters. Such a decrease in motivation can be a main driver for students …

Background: There are indications that older adults who suffer from poor balance have an increased risk for adverse health outcomes, such as falls and disability. Monitoring the development of balance over time enables early detection of balance decline, which can identify older adults who could benefit …

This research was conducted as a response to the recent trend of flexibilization in the European labor market. Factors for its fast emergence include the increased international competition and the effects of the economic crisis in Europe. Young workers have become overrepresented in flexible jobs. The …

With a market demand for low cost, easy to produce, flexible and portable applications in healthcare, energy, biomedical or electronics markets, large research programs are initiated to develop new technologies to provide this demand with new innovative ideas. One of these fast developing technologies …

In this study, we experimentally investigated the material flows of coloured dyes in coalescing small inkjet printed droplets of different volume ratios. With two differently coloured dyes, one in each droplet, we were able to distinguish the time-resolved contributions in dye transport across the coalescence …

In reaction to the lack of intrinsic motivation of construction site workers, to wear their safety helmets at all times, a series of research projects studied causes and possible solutions. Goal is to gain an inspirational discussion to get the design onto the next level. This paper describes a study …
