The effect of pulsations in conditions related to catalytic converters

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...

A method for lower back motion assessment using wearable 6D inertial sensors

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...

Combining Insar, levelling and GNSS for the estimation of 3D surface displacements

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...

System Dynamics and Serious Games

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...

Phase-locked stereoscopic PIV measurements of the turbulent swirling flow in a dynamic model of a uniflow-scavenged two-stroke engine cylinder

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...

Integrated, Ecosystem-based Marine Spatial Planning: First Results from International Simulation-Game Experiment

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...

Gaming as the method to integrate modeling participatory approaches in interactive water management

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...

Cluster optical coding – from biochips to counterfeit security

Spatially tuned resonant nano-clusters allow high local field enhancement when excited by electromagnetic radiation. A number of phenomena has been described and subsequently applied for the construction of novel nano- and bionano-devices. Easy to manufacture, cost efficient and high throughput transducers using metal cluster resonance...
