Noise reduction at low frequencies is a major issue in many workspaces and indoor public places. Unlike mid- and high-frequency noise, low frequency noise is less attenuated by using conventional sound absorbing materials. This communication proposes an electro-mechano-acoustic absorber ...

Most of existing material representations [1], even including the dynamic hysteresis and iron losses [2], ignore local microscopic non-uniformities. These concern the magnetic structure (domains and walls [3]) and are mainly due to surface effects, anisotropy and exchange [4]. One ... En savoir plus
The flow simulation of solid, particulate materials is still challenging, even though estimations show that three-quarters of products and raw materials are present as granules form in the industry. We can think of grain in the agriculture, raw materials of the glass industry, granulated ... En savoir plus
Quiet zones and other sound zones have been a strong topic of research for some time, due to the interest of creating separate sound environments in a same room, in a large open-space office for example. A number of solutions have been proposed over the last years. This paper further ... En savoir plus
Background and novelty Organ-on-a-chip-systems represent a powerful alternative to substance testing in animal trials. The basic idea behind this approach is to emulate the smallest physiological unit of an organ on a chip. For this purpose, micro-environments must be created, that ... En savoir plus
Brain-Machine Interfaces (BMI) provide a direct communication link between brain and external devices such as speech synthesizers and robotic prosthesis to restore speech and movement in persons affected by Spinal Cord Injuries or neurodegenerative diseases such as Amyotrophic Lateral ...

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus
Thermal energy storage systems receive notable attention within the framework of energy management due to their ability of bridging thermal energy demand and supply, thus leading to an overall efficiency increase. The key component in such systems are materials which convert ... En savoir plus
The conversion of steel mill off-gases to base chemicals is a promising perspective to improve the financial return of steelmaking in Europe and fight CO2 emissions. In the Carbon2Chem® joint research project, mathematical models are developed to simulate operation scenarios of cross ... En savoir plus
Real-time microstructure monitoring is important during the cooling process for hot-rolled strip steel production, as the microstructure formed determines the mechanical properties required by customers. The materials magnetic and electric properties, relative permeability and ... En savoir plus
