At the loudspeaker system designing, especially for bass zone, many things have be taken to account. First it is loudspeaker, secondary loudspeaker’s baffle board. For [...]

The paper deals with optimization process finding such geometrical form of acoustical cavities of the human supraglottal spaces which leads to excitation of predefined ac [...]

The composite tube fabricated from elastomer matrix reinforced with NiTi wires was tested within simultaneous inflation and extension. Four different longitudinal weights [...]

An optimization method for the determination of elastic moduli by resonant ultrasound spectroscopy (RUS) was proposed. All components of the fourth-order tensor of elasti [...]

Acoustic speech output in humans is commonly considered to results from a combination of a source of sound energy (e.g. the larynx) modulated by a transfer (filter) funct [...]

The pendulum damper modelled as a two degree of freedom strongly non-linear auto-parametric system is investigated using an approximate differential system. Uni-direction [...]

This article deals with the use of the resonance method for detection and inspection of defects in inhomogeneous isotropous materials having properties depending on tempe [...]

The paper is devoted to the analytical and experimental stress analysis in aluminum tube of car air – conditioner at static and dynamic loading at test equipment. After [...]

The contribution deals with the straight sandwich bar element derived by new nonincremental full geometric nonlinear approach. We assume a twonode straight sandwich compo [...]

In this paper there is described a method for measurement of resonant frequency of longitudinally vibrating aluminum bar. The bar is of a shape of tube and inside in the [...]
