We demonstrate that artificial neural network modeling is a viable tool to predict the processing dependence of gravure printed light-emitting polymer layers for flexible OLED lighting applications. The (local) thickness of gravure printed light-emitting polymer (LEP) layers was analyzed using microdensitometry, after which the data was used to...

High-speed imaging, spectroscopy and thermodynamical characterization are applied to an optically accessible, heavy-duty diesel engine in order to compare sooting and chemiluminescence behaviour of bio-derived, oxygenated fuels and various reference fuels. The fuels concerned include the bio-derived fuels Jatropha oil (pure), Jatropha...

The Variable-Flow Ducted Rocket (VFDR) is a type of ramjet that can control the fuel mass flow to the combustion chamber. It combines the high efficiency at high-speed of ramjets with the throttlability of turbofans, and this makes VFDR propulsion an excellent choice for high speed, long range missiles. This is especially true because the...

The c-congestion period, defined as a time interval in which the number of customers is larger than c all the time, is a key quantity in the design of communication networks. Particularly in the setting of M/M/∞ systems, the analysis of the duration of the congestion period, D<sub>c</sub>, has attracted substantial attention; related quantities...

This paper investigates the effects of dynamic road marking on the Ring around Amsterdam. This Ring is congested during most of the day, but especially during the peak periods in the morning and evening rush hours. The goal is to determine what (traffic) effects, if any, can be found by applying Dynamic Road Marking during the morning rush hours...

The mapping method has proven its efficiency as an analysis and optimization tool for mixing in many different flow devices. In this paper, we present a new approach to compute the coefficients of the distribution matrix, which is, both in terms of computational speed and complexity, more easy to implement as compared to the original approach...

A green wave on a road enables a driver to negotiate a sequence of signalized intersections without hitting red. This is accomplished by the coupling of a series of signalized intersections. This is an advantage for driver comfort, for flow and safety on the road network, and for the environment. Providing speed advice may help the driver to...

This paper describes an ongoing research project in the Netherlands for lowering the speed limit, depending on the weather condition (in particular rain) to enhance traffic safety. The research in this project consists of three main parts. In the first part, research has been conducted on the strategy of speed limits to be displayed: in what...

Ramjet propulsion is often proposed for airbreathing applications with speeds higher than Mach 3. However, for speeds higher than Mach 5, the performance of a ramjet drops significantly and the scramjet is the preferred option. The shock-induced combustion ramjet, or shcramjet, is also an interesting alternative at higher flight speeds. Its...

De mobiliteit van personen en goederen is onmisbaar binnen ons dagelijks leven en maatschappij. In Nederland nemen 7 miljoen personenauto's ruim 80% van onze verplaatsingen voor hun rekening. Zo'n 60% van de goederen wordt over de weg vervoerd en 30% over het water. Berekeningen van het ministerie van Verkeer en Waterstaat voorspellen een...

The force acting on a current carrying body, which is induced by magnetic fields gained more interest due to new applications. These magnetic techniques are used for decades to accelerate or move objects, for instance for catheter navigation in the human body, metal forming or for fast opening of electrical circuit breakers. Due to the increase...

Does consideration of average speed distributions on roads-as compared to single mean speed-lead to different results in emission modelling of large road networks? To address this question, a post-processing method is developed to predict mean speed distributions using available traffic data from a dynamic macroscopic traffic model (Indy) that...

Sea surface images obtained during the 2006 Marine Aerosol Production (MAP) campaign in the North East Atlantic were analysed for values of percentage whitecap coverage (W). Values of W are presented for wind speeds up to circa 23 m s-1. The W data were divided into two overlapping groups and a piecewise, wind-speed-only parameterization of W is...

In recent years, TNO has developed a water-filled interferometer, which is able to determine acoustical properties of a sound absorbing material or a compliant layer like the Alberich coating. The frequency range of the measurements is 1.5 to 20 kHz. The main results are mostly in the form of absolute reflection losses of the material mounted...

This paper describes the results of a driving simulator study that focused on the influence of roadside infrastructure on speed choice and lateral placement of car drivers. A review of the RISER detailed accident database revealed that lateral positioning and speed of the vehicle were two of the primary factors leading to crashes. The driving...

Track decay rates are an important quanty relevant for raiway rolng noise. The vertical and ateral track decay rates are used to characterise he dynamc behaviour of the rack, both as an nput to calculations and for track characterisation given n EU regulations (TSIs). TNO has developed ethods and software capable of deriving he decay rates,...

Traction noise is one of the noise sources of powered railway vehicles such as locomotives, electric- and diesel-powered multiple unit trains and high-speed trains. Especially at speeds below 60 km/h and at idling, but also at acceleration conditions for a wide range of speeds, traction noise can be dominant. This is relevant for noise in...

Co-operative driving with speed adaptation functionality has great potential to improve traffic-throughput, traffic-safety, and environmental-impact on heavily used traffic-infrastructures. A driving-simulator study was performed to investigate the driver behaviour with respect to such driver-support systems (Zero-, Advisory-, Intervention-, and...

Road traffic noise is one of the major environmental noise sources that is known to cause health problems. Despite existing noise reception items, the continuing growth of traffic causes higher levels than the lims allow. Consequently, excessive costs are incurred for noise barriers along roads and motorways. It's therefore essential to...
