The following study presents some considerations on different subjects regarding the field of art, from the art of using sounds in theatre and the importance of the Greek tragedy to the subtle differences between opera and theatre. The sound experiment is to be approached knowing that the audience is, in some way, deaf. The renewal of the sounds, even of those coming forth from the remote ages, is part of the author’s lust for a theater that celebrates real contact and real feeling, with a unique expression of force, of intense colors and sharp energies. The main goal is to discover the actor’s or the opera singer’s work with the sounds, with the vibration of the words in his body, thus investigating the “meanings” of the pure sound.

The following report shows methods for determination of the coefficients of stiffness and damping, for softening the vibrations, which ensue in an armoured vehicle’s suspension from the shooting of a mounted machine-gun. The methods are based on a model of the movement smoothness, in which is additionally included the signal of the machine gun’s recoil.

This paper presents thermal analysis with finite elements for a plate of steel covered on the surface with a thin layer of Teflon. There is the possibility of identification of that part responsible for beginning of the thermal degradation using the vibrational model. The thermal analysis with finite elements made with ANSYS program enables monitoring and determination of plate variation of temperature. This variation of temperature could cause significant changes in guided wave propagation.
