The present work analyses broadband noise scattering from permeable trailing edges with identical micro-structure but under a change of temperature. Experiments are performed in an anechoic wind tunnel using a NACA0018 airfoil at chord-based Reynolds numbers between 1.88 × 10<sup>5</sup> and 3.14 × 10<sup>5</sup> and no incidence. A...

For many aerospace applications, the dominant airfoil self-noise source is Turbulent Boundary Layer Trailing Edge (TBL-TE) noise. The replacement of solid airfoil trailing edges with permeable materials proved to be an adequate noise reduction mean in previous studies. This thesis project contributes to the development of innovative permeable...

Self-aggregating calix[4]arenes carrying four DOTA ligands on the upper rim for stable complexation of paramagnetic GdIII-ions have already been proposed as MRI probes. In this work, we investigate the luminescence properties of TbIII-DOTA-calix[4]arene-4OPr containing four propyl-groups and compare them with those of the analog substituted with...

The effect of pulsations in a catalyst converter is investigated with the aim of determining if a steady flow captures the same physical phenomena as the pulsating flow. For this specific case, guide vanes are mounted in the sudden expansion to obtain a uniform inlet flow to the catalytic layers. The test rig is successfully validated against...

Low back pain (LBP) is a leading cause of activity limitation. Objective assessment of the spinal motion plays a key role in diagnosis and treatment of LBP. We propose a method that facilitates clinical assessment of lower back motions by means of a wireless inertial sensor network. The sensor units are attached to the right and left side of...

Nuclear safety governance should move towards a more robust regime including elements of international monitoring and verification. This is needed because nuclear energy production is likely to grow and new reactors will have different global dispersal, veering towards less experienced countries. In addition, there is growing interest in...

The applicability and limitations of sulphur isotope ratio as a nuclear forensic signature have been studied. The typically applied leaching methods in uranium mining processes were simulated for five uranium ore samples and the n(<sup>34</sup>S)/n(<sup>32</sup>S) ratios were measured. The sulphur isotope ratio variation during uranium ore...

Among the procedures to prepare lanthanide-containing nanoparticles a gap exists in the range between 5 and 40 nm. The miniemulsion technique presented here is intended to fill this discontinuity and offers a facile method that can be applied for the preparation of nanoparticles for various applications, e.g. medical imaging, optics and...

The three geodetic techniques InSAR, levelling and GNSS are complementary w.r.t. (i) the sensitivity to horizontal and vertical displacement components, (ii) the spatial and temporal resolution of the measurements and (iii) the accuracy of the resulting displacements. We present a strategy to robustly combine the displacement estimates of the...

This paper deals with the relationship between serious games and system dynamics. Games have been used in SD since the beginning. However, the field of serious gaming also has its own development. The purpose of this contribution is to provide a broad overview of the combination of serious gaming and SD and discuss the state of the art and...

A novel procedure has been developed for the measurement of 143Nd/144Nd isotope ratio in various uranium-bearing materials, such as uranium ores and ore concentrates (UOC) in order to evaluate the usefulness and applicability of variations of 143Nd/144Nd isotope ratio for provenance assessment in nuclear forensics. Neodymium was separated and...

It is desirable to use computational fluid dynamics for the optimization of in-cylinder processes in large two-stroke low-speed uniflowscavenged marine diesel engines. However, the complex nature of the turbulent swirling in-cylinder flow necessitates experimental data for validation of the used turbulence models. In the present work, the flow...

Enhancing the offer for entrepreneurship education is an important challenge for the nowadays knowledge societies. The eSG project is addressing this issue by analysing the added value that could be contributed by employing serious games (SGs) as a tool for allowing students – in particular technology students - to become familiar, mainly...

Marine ecosystems around the globe are increasingly affected by human activities such as fisheries, shipping, offshore petroleum developments, wind farms, recreation, tourism and more. Whereas the necessity and urgency to regulate and plan competing marine spatial claims is growing, the planning and regulation of these claims is even more...

At the science - policy interface there are several reasons to combine models with the participatory process to facilitate the complex policy making process but the communication of the two sides is often too hard to generate any meaningful results. In this paper we argue that to close the communication gap the rationale of the Meta – rule of...

Het valt moeilijk te ontkennen dat spelsimulaties, of serious games, intrigerende instrumenten zijn om te experimenteren en te leren; niet alleen als didactiek of voor bedrijfs- en managementtrainingen maar ook in het kader van beleids- en organisatieontwikkeling in de publieke sector. Ondanks de huidige aandacht voor (serious) gaming is de...

In deze bijdrage laten we zien dat gaming een effectieve methode is om een socio-technisch systeemontwerp, zoals een nieuw informatiesysteem, financieringsstelsel of besturingsmodel integraal uit te proberen en te testen voorafgaand aan de vaststelling of invoering ervan. We bespreken twee cases waarin gaming op deze wijze is gebruikt: de...

In 1995 heeft Bestuurskunde aandacht besteed aan een voor de bestuurskunde wat ‘exotisch’ onderwerp, namelijk ‘spelsimulaties’. Het betreffende themanummer bestond uit vier bijdragen onder gastredactie van prof. Jac Geurts (e.a.), hoogleraar Beleids- en Organisatiewetenschappen in Tilburg. Inmiddels zijn we meer dan een decennium verder. Een...
