Combined sound and vibration measurements during train pass-bys can be used to quantify contributions from the excitation and transmission of rolling noise. This is useful for the identification of sound sources and the assessment of the track contribution. In this paper, a practical application on a high-speed track is discussed. Acoustic...

The assessment of the structural safety of existing bridges and viaducts becomes increasingly important in many countries. Within the actions applied to the bridges, the traffic load is, in general, the most significant variable action to be considered when the ultimate limit states are under investigation. Over the last years a considerable...

Since 2006, a number of countries developed reports on climate change following the IPCC 4th assessment reports. For the Netherlands, the Royal Netherlands Meteorological Institute (KNMI) presented four new climate scenarios. Typically, climate change is described in terms of average changes, but much of the social and economic costs associated...

Inkjet printing is a nascent technology that developed during the last decades from only printing text and graphics into an important scientific research tool for R&D, where printers are used as a highly reproducible non-contact patterning tool. In contrast to lithography, inkjet printing is an additive technique that requires only small amounts...

RF arc detection is a key operational and safety issue for ICRF systems. Dedicated measurements on a RF test-stand were made in order to characterize the optical signature of RF arcs (time and spectrum) to assess the potential of optical arc detection on ICRF systems. Time-resolved intensity measurements were carried out using high-speed Si...

A comprehensive programme of field trials with several new applications of dynamic (or variable) speed limits on motorways was carried out in The Netherlands in the years 2009- 2010. The objective of the programme was to gain more insight into the impact of dynamic, tailor made speed limits on various policy goals. Innovative solutions were...

The goal of the presented study was to explore how simulator motion cueing affects the driver’s control performance of a car. We looked at steering behavior as a measure of control performance. The experimental task was a slalom maneuver where the car velocity was limited to 70 km/h. Subjective and objective variables were measured. This paper...

High-speed milling is often used in industry to maximize productivity of the manufacturing of high-technology components, such as aeronautical components, mold, and dies. The occurrence of chatter highly limits the efficiency and accuracy of high-speed milling operations. In this paper, two control strategies are presented that guarantee a...

Two major trends can be identified for powertrain control in the next decade. The legislation will more and more focus on in-use emissions. Together with the global trend to reduce the CO 2 emissions, this will lead to an integral drive train approach. To develop and validate this integral drive train approach, the need for a new chapter in...

Applications are given of a preconditioned adaptive algorithm for broadband multichannel active noise control. Based on state-space descriptions of the relevant transfer functions, the algorithm uses the inverse of the minimum-phase part of the secondary path in order to improve the speed of convergence. A further improvement of the convergence...

The aim of this study was to provide a detailed description of the fracture mechanisms in three different biopolymer thin materials: gelatin, hydroxypropyl cellulose (HPC) and cassava starch films. That was achieved by using a combination of fracture mechanics methodology and in situ visualization with high speed imaging technique. By analyzing...

Within the HySafe Network of Excellence, several organizations with experience in numerical combustion modeling participated to Standard Benchmark Exercise Problem 2 (SBEP-V2), trying to reproduce numerically the explosion of a stoichiometric hydrogen-air mixture in a 10 m radius balloon. Different codes and models have been applied in the...

Energy Management Strategies for hybrid powertrains control the power split, between the engine and electric motor, of a hybrid vehicle, with fuel consumption or emission minimization as objective. Optimal control theory can be applied to rewrite the optimization problem to an optimization independent of time. Estimation of the Lagrange...

Chatter is an instability phenomenon in machining processes which limits productivity and results in inferior workpiece quality, noise and rapid tool wear. The increasing demand for productivity in the manufacturing community motivates the development of an active control strategy to shape the chatter stability boundary of manufacturing...

In this Communication we show that with spatially separated ALD of Al2O3 growth rates of 1.2 nm s-1 can be achievd, showing excellent surface passivation (surface recombination velocities of <2 cm s-1). This implies a revolutionary breakthrough in industrial throughput ALD of Al2O3 passivation of silicon solar cells.

A speed limit of 80km/h with "strict enforcement" has been introduced in 2005 on zones of urban motorways in The Netherlands with the aim to improve air quality of NO2 and PM10 along these motorways. Strict enforcement means speed control by camera surveillance over the whole trajectory of 2-4km combined with licence plate recognition and...

Bubbles bursting from whitecaps are considered to be the most effective mechanism for particulate matter to be ejected into the atmosphere from the Earth's oceans. To realistically predict the climate effect of marine aerosols, global climate models require process-based understanding of particle formation from bubble bursting. During a cruise...

The Harmonoise sound propagation model ('the Harmonoise engineering model') was developed in the European project Harmonoise (2001-2004) for road and rail traffic noise. In 2008, CSTB Grenoble and TNO Delft have prepared a detailed description of the various steps involved in a calculation with the Harmonoise model. In the course of this joint...

Spatial planning in urban areas is complex. Besides noise from different source types, many other aspects play a role. In order to support local authorities and others involved in spatial planning, TNO has developed an interactive instrument: 'Urban Strategy', which integrates a detailed interactive noise map with other aspects such as traffic...
