Measuring geoacoustic parameters of underwater sediments is important for accurate modeling of underwater acoustic propagation. While the density and compressional wave speeds can be directly measured in sediments, shear wave speeds are difficult to measure because they are highly ... En savoir plus

In recent years, studies on robotics have been needed, to utilise the tactile sensors for artificial skin. Researchers have been working on tactile transduction technologies which lead to many sensor prototypes and devices for robotic applications in their effort to solve the tactile ... En savoir plus

The vibration of an electrodynamic loudspeaker driver causes a resulting sound pressure. For simple pistonic vibration, there is a simple relationship between the vibration and the sound pressure. For complex vibration patterns, however, different parts of the vibrating surface ... En savoir plus

The geometrical design and material choice for a refractory lining requires a good understanding of its thermo-mechanical behavior. Design engineers clearly need a tool for fast and efficient computation of thermo-mechanical state of refractory linings under various conditions. However, ... En savoir plus
