Traffic noise pollution has represented a significant challenge for modern societies, requiring the development of innovative noise mitigation strategies. In the last decades, intensive research has been developed into the design and evaluation of noise barriers but there still lacks a ... En savoir plus

Acoustic landmine detection is accomplished using a loud speaker as an airborne source to generate low-frequency waves that enter the soil at a certain incident angle. At a specific frequency, the landmine will "vibrate" at resonance, imparting a certain velocity on the soil particles ... En savoir plus

The right way to design dedicated controller for a particular device or process is to compute an adequate and representative model. In the case of Magnetic Levitation Systems, the mathematical modelling via ordinary differential equations is limited by the analytical functions ... En savoir plus

Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... En savoir plus

Friction stir welding (FSW) is a revolutionary technique for joining high-strength materials, offering superior mechanical properties compared to traditional fusion welding methods. However, achieving optimal surface quality in FSW of Inconel 718 is challenging due to the material's ... En savoir plus

The measurement and regulation of particulate matter to improve outside air quality advanced a lot over the last decades. This also made it necessary to develop primary standards for calibrating these measurement systems and in future the composition of relevant aerosols will be taken ... En savoir plus

Stirred tank bioreactors are used to simulate a natural biochemical environment for the optimum growth of cells (i.e. algae, microorganisms or tissues) in microbial and cell culture. Bioreactor types range from small (5 L and less) up to 15000 L systems for large-scale industrial ... En savoir plus

The coaxial magnetic gear is a good alternative to classic mechanical gears. The magnetic gear has high mechanical durability, overload protection and lower noise, than a mechanical gear [1,2]. A static model of a magnetic gear [3,4] is used for simulation of the magnetic fields and ... En savoir plus

The mitral valve apparatus is a complex and refined mechanism located between the left atrium and the left ventricle of the heart which can manifest various kinds of pathologies. In order to support identification of potentially critical conditions resulting from some typical ... En savoir plus
