The applicability of laser ultrasonics for the determination of grain size and phase composition in steels under different temperatures was investigated. This was done by obtaining the velocity and attenuation of propagating ultrasonic waves in a simulated steel medium. Samples of ferrite and austenite with varying microstructures were modelled...

Background Pesticides can be transported from the site of application to homes via different routes and lead to exposure of residents, raising concerns regarding health effects. We built a deterministic model framework (OBOmod) to assess exposure of residents living near fields where pesticides are applied. Methods OBOmod connects five...

ISO standard 17201-4 is a calculation method for sound levels generated by supersonic bullets. The standard takes into account nonlinear propagation effects, including broadening of a sound pulse with increasing propagation distance. Two elements of the ISO method are investigated in this paper: i) the accuracy for various Mach numbers, and ii)...

Noise contours around military training areas are calculated by using: a) the measured source strength for the impulsive sources and b) the calculated sound propagation using a representative set of meteorological situations. For high-energy impulsive sounds the source strength is measured at distances beyond 100 meters, where peak levels are...

This tool paper presents iDSL, a language and a fully automated toolchain for evaluating the performance of service-oriented systems. In this work, we emphasize the use of a high-level domain specific language that is tailored to be understood by system designers and domain experts, a transformation into an underlying process algebra which...

Frisse lucht zorgt voor een goede en diepere slaap. Dus bieden veel kinderdagverblijven de mogelijkheid om kleintjes buiten te laten slapen. Kan dat onder alle weersomstandigheden? En waar let je op als het bijvoorbeeld pijpenstelen regent of vriest dat het kraakt?

De stap van universiteit naar overheid die ik tien jaar geleden maakte, ging samen met het meer bezig zijn met een andere kant van geluid: van een technische kant naar de sociaal-psychologische kanten van geluid. Dit artikel gaat over de integratie van beide kanten

Service-oriented systems interconnect with other systems in a time critical manner, making their performance vital. For this purpose, we propose an automated performance evaluation approach for service-oriented systems which includes both performance measurement and prediction. The approach makes use of the iDSL language, a domain specific...

Service-oriented systems are designed for interconnecting with other systems. The provided services face timing constraints, the so-called latencies. We present a high-level performance evaluation technique that can be used by a system designer to obtain distributions of these latencies. This technique is capable of capturing nondeterministic,...

In urban areas, road traffrc noise is a dominant source of environmental noise and a major cause of noise annoyance and disturbed sleep. It has been hypothesized that respondents highly exposed to noise at multiple sides of their dwelling, may be expected to be worse off than respondents with the same exposure at the most exposed side, but also...

The increasing complexity of embedded systems requires performance evaluation early in the design phase. We introduce a generic way of generating performance models based on a system description given in a domain-specific language (DSL). We provide a transformation from a DSL to a performance model in the Parallel Object-Oriented Specification...

Previous studies indicate that residents may benefit from a "quiet side" to their dwellings. The influence of the level of road traffic noise exposure at the least exposed side on road traffic noise annoyance was studied in Amsterdam, The Netherlands. Road traffic noise exposure was assessed at the most and least exposed façade (Lden,most and...

Quiet façades and quiet areas may reduce effects of road traffic noise by offering the possibility to avoid the noise to some extent for the inhabitants. To date a limited number of studies have investigated this hypothesis. Further quantification of the effect size will be helpful to enable estimation of a beneficial effect on people. Within...

Much environmental research is performed on predicting the noise impact of heavy weapons or explosives, as the shock waves can propagate over large distances. In the densely populated area of the Netherlands this is of particular interest for the Ministry of Defense. In one research program the mitigation of shock waves close to the source has...

Semi-open shooting ranges, in contrast to a fully open shooting range, are often used in the densely populated area of the Netherlands. The Ministry of Defense operates a number of these ranges. In these shooting ranges above the line of fire a number of screens are situated for safety precautions to prevent bullets to exit the range. When a...

The Dutch project “Geluid in Beeld” (A view on sound), investigates the impact of industrial sound from the Europort/Maasvlakte area towards the city of Oostvoorne. The reason for this project are unexpected noise complaints, see 1. The project was initiated by The Port of Rotterdam, DCMR, EMO and ECT. This paper presents the comparison of the...

Long range sound propagation is largely affected by the vertical wind and temperature gradients. In areas where the meteorology can be complex, such as coastal areas, islands, and lake districts, the gradients usually vary as a function of the horizontal distance. As a result the sound propagation in these areas cannot be calculated with ...

A new approach for an airport noise monitoring system is presented that comprises not only a number of measuring stations, but also a dedicated sound propagation model and an aircraft noise emission model. This approach enables estimation of noise levels in the whole area around the airport and not only at the location of the measuring stations....

Large weapons, such as armor, artillery or demolitions, create a high-energy blast wave. It has a low frequency content, typically between 15 and 125 Hz, and can propagate over large distances. As a result it is a relative important cause for annoyance. Mitigation measures need to be close to the source for best effectiveness, but due to the...

A blast absorber test was conducted at the Aberdeen Test Centre from 13 to 17 June 2005. The test was set up to determine the absorbing and shielding effect of a gravel pile, of 1.5 meters high and 15 by 15 meters wide, on blasts from large weapons: e.g. armor, artillery or demolition. The blast was simulated with single brick C-4 charges of 570...
