A Domain-Specific Language and Toolchain for Performance Evaluation Based on Measurements

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...

Simulation of an oil film at the sea surface and its radiometric properties in the SWIR

The knowledge of the optical contrast of an oil layer on the sea under various surface roughness conditions is of great interest for oil slick monitoring techniques. This paper presents a 3D simulation of a dynamic sea surface contaminated by a floating oil film. The simulation considers the damping influence of oil on the ocean waves and its...

A structured approach to increase situational awareness in low voltage distribution grids

Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value model which relates sensor data...

Uncertainty quantification of aeroacoustic power sources in corrugated pipes

Gas transport in corrugated pipes often exhibit whistling behavior, due to periodic flow-induced pulsations generated in the pipe cavities. These aero-acoustic sources are strongly dependent on the geometrical dimensions and features of the cavities. As a result, uncertainties in the exact shape and geometry play a significant role in...

The influence of adverse weather conditions on probability of congestion on dutch motorways

Weather conditions are widely acknowledged to contribute to the occurrence of congestion on motorway traffic by influencing both traffic supply and traffic demand. To the best of our knowledge, this is the first paper that explicitly integrates supply and demand effects in predicting the influence of adverse weather conditions on the probability...

Efficient contrast enhancement through log-power histogram modification

A simple power-logarithm histogram modification operator is proposed to enhance digital image contrast. First a logarithm operator reduces the effect of spikes and transforms the image histogram into a smoothed one that approximates a uniform histogram while retaining the relative size ordering of the original bins. Then a power operator...

Estimation of the consumption of cold tap water for microbiological risk assessment: An overview of studies and statistical analysis of data

The volume of cold tap water consumed is an essential element in quantitative microbial risk assessment. This paper presents a review of tap water consumption studies. Study designs were evaluated and statistical distributions were fitted to water consumption data from The Netherlands, Great Britain, Germany and Australia. We conclude that the...

SPECTRALON diffusers used as in-flight optical calibration hardware

The Medium Resolution imaging Spectrometer (MERIS), developed under European Space Agency (ESA) contract, for the Envisat 1 Polar Orbit Earth Mission belongs to a new generation of Ocean Color sensors which aim to improve the knowledge of some crucial processes of our planet. The instrument currently in the final stages of development is built...
