Estimating the gain of an antenna prototype is an important step during both design and validation phases. Nevertheless, many small technology companies and universities are not provided with adequate infrastructure to run this type of test. In this paper, we propose a computational tool to deal with undesirable contributions coming from non-ideal ...

Rheological parameters being of great importance for sludge process management, they are increasingly studied. However, experimental procedures may strongly impact their determination. Sample volume, measuring device depth and roughness but also mechanical history, have to be well-controlled to ensure reproducible results. Indeed, even if shear his...
12th International Workshop on Structural Health Monitoring, IWSHM, STANFORD, ETATS-UNIS, 10-/09/2019 - 12/09/2019
The pooling of results from three French projects (Matriochkas, MicroMégas and Roulépur), within the framework of a working group on methodological harmonisation, makes it possible to analyse the performance of a wide range of stormwater control measures (SCMs) in terms of micropollutant load reduction. Data covers 12 management systems, in 9 diffe...
Noise emission is a major concern for residents living along railway lines. For a large range of conventional speeds, railway noise is dominated by rolling noise. The contribution of the track to rolling noise is mainly driven by the level of rail roughness and the Track Decay Rate (TDR). The MEEQUAI project (on-board measurement of the acoustic qu...
Pour les riverains des infrastructures ferroviaires, les émissions acoustiques constituent une préoccupation de premier plan. Parmi les sources incriminées, le bruit de roulement est prépondérant pour une large gamme de vitesses d'exploitation. Pour ce qui est de l'infrastructure, le niveau de bruit de roulement est principalement déterminé par deu...
Awareness of the health effects of noise gradually became apparent in the second half of the 20th century, in contrast to the parallel urban planning decisions, which left a significant place for the automobile in the city. The high noise levels, combined with the increasing aspiration of city dwellers for a peaceful and environmentally friendly ci...
The friction measurement devices being used today in accordance with various international standards for the assessment of surface conditions on highways and runways are numerous. Although among the different equipment designs there are only a few substantially different measurement principles, they all have a significant number of design and opera...
Sound level predictions are based on both simplified emission and propagation models able to deal with transport and industrial sources only, thus neglecting other sound sources which yet contribute to urban soundscapes. Sound level assessment can take advantage of acoustic measurements if a sufficient amount of sensors is deployed to pick up the v...
