The theory of relativity of motion: A new approach

For more than a century, people’s belief about special relativity and its formulas was, in fact, inaccurate, because Einstein fails by delaying in the wrong conception. However, one of these formulas is correct, by chance, but the others are incorrect. In the present approach, new expressions for time dilatation, composition of velocities, different masses (energy and inertial masses) and energy are demonstrated...

The strength of the atom localization coupling with the standing-wave field under the dephasing rate influence

We investigate the localization of the four-level V-type atom inside a classical standing-wave field through the absorption spectrum of the weak probe field. The expression of the probe absorption spectrum is derived analytically via perturbation treatment of a weak probe field. Numerical results and discussion of the probe susceptibility spectrum behaviour via non-perturbation treatment of the density matrix elements...

Surface waves propagation in fibre-reinforced anisotropic elastic media subjected to gravity field

The objective of this paper is to investigate the surface waves in fibre-reinforced anisotropic elastic medium subjected to gravity field. The theory of generalized surface waves has firstly developed and then it has been employed to investigate particular cases of waves, viz., Stoneley waves, Rayleigh waves and Love waves. The analytical expressions for waves velocity and attenuation coefficient are obtained in the...

Estimated electric power consumption by means of artificial neural networks and autoregressive models with exogenous input methods

The growth electric energy demand in the industrial and commercial sectors and in public and private buildings represents a problem to estimate electrical consumption in these sectors in order to avoid fines imposed by the respective companies supplying electricity. This study presents artificial neural networks (ANN) and autoregressive models with exogenous input (ARX) models to calculate and to predict the electrical...

Effects of adhesive thicknesses on the stress distribution in prismatic plug-in joints

  The aim of this study is to research the effects of adhesive thickness, which is one of the factors that affect the stress distribution in the prismatic plug-in joints. The effect of adhesive thickness was theoretically researched in the study. Epoxy-based and acrylic-based adhesives, which are widely used in combining metal joints, were applied. After testing the mechanical characteristics of the adhesives,...
