In this paper, we present a sonification strategy developed for electric vehicles aiming to synthetize new engine sound enhance the driver’s dynamic perception of vehicle. We chose mimic internal combustion (ICE) noise by informing driver through pitch variations. However, ICE variations are correlated engine’s rotations per minute (RPM) and its dynamics is covered within limited vehicle speed ...

A certain class of photonic crystals with conical dispersion is known to behave as isotropic zero-refractive-index medium. However, the discrete building blocks in such photonic crystals are limited to construct multidirectional devices, even for high-symmetric photonic crystals. Here, we show multidirectional emission from low-symmetric photonic crystals with semi-Dirac dispersion at the zone ...

Living organisms are high ordered and organized systems accumulating and successively using low entropy energy to support all the processes needed for life. This low level of entropy is a required condition in order to make possible the use of endogenous energy for producing, for example, mechanical work. The commonly accepted picture of condensed matter physics, exclusively considering the per...
