Correspondingly, the theoretical models that describe the complex systems dynamics become more and more advanced [ -]. For all that, this problem can be solved by taking into account that the complexity of the interaction process implies various temporal resolution scales, and the pattern evolution implies different degrees of freedom [ ].[In order to develop new theoretical models we must state the fact that the complex systems displaying chaotic behavior are recognized to acquire self-similarity space-time structures can appear in association with strong fluctuations at all possible space-time scales [ -]. "fterwards, for temporal scales that are large with respect to the inverse of the highest Lyapunov exponent, the deterministic trajectories are replaced by a set of potential trajectories and the concept of definite positions by that of probability density] [ ]. "n interesting example is the collisions processes in complex systems, where the dynamics of the particles can be described by non-differentiable curves.Since non-differentiability can be considered a universal property of complex systems, it is mandatory to develop a non-differentiable physics. In this way, by considering that the complexity of the interaction processes is replaced by non-differentiability, using the entire range of quantities from the standard physics differentiable physics is no longer required [ ].This topic was developed in the Scale Relativity Theory SRT [ , ] and in the non-standard Scale Relativity Theory NSSRT [ -]. [In the framework of SRT or NSSRT we assume that the movements of complex system entities take place on continuous but non-differentiable curves fractal curves so that all physical phenomena involved in the dynamics depend not only on the space-time coordinates but also on the space-time scales resolution. In this conjecture, the physical quantities that describe the dynamics of complex systems can be considered as fractal functions. In addition, the entities of the complex system may be reduced to and identified with their own trajectories. In this way, the complex system's behavior will be identical to the one of a special interaction-less fluid by means of its geodesics in a nondifferentiable fractal space] [ , , ].In such context notions as informational entropy, Onicescu informational energy etc become important in the Nature description. These notions will be correlated with the fractal part of the physical quantities that describe the dynamics of complex systems. . Informational entropy and energyIndependently of scale resolution, the motion, either on infragalactic scale for instance, the planetary motion , or on atomic scale for instance, the motion of the electron around its nucleus takes place on conics ellipses . Such motion in invariant with respect to the SL R group. In what follows, we shall consider this invariance only with respect to the motion on atomic scale. . .

“…Moreover, the entities of the complex system may be reduced to and identified with their own trajectories, so that the complex system will behave as a special fluid lacking interaction (via their geodesics in a non-differentiable (fractal) space).

Considering that the movements of complex system entities take place on continuous, but non-differentiable, curves, concepts, like non-differentiable entropy, informational non-differentiable entropy and informational non-differentiable energy, are introduced.First of all, the dynamics equations of the complex system entities (Schrödinger-type or fractal hydrodynamic-type) are obtained. The last one gives a specific fractal potential, which generates uncertainty relations through non-differentiable entropy. Next, the correlation between informational non-differentiable entropy and informational non-differentiable energy implies specific uncertainty relations through a maximization principle of the informational non-differentiable entropy and for a constant value of the informational non-differentiable energy. Finally, for a harmonic oscillator, the constant value of the informational non-differentiable energy is equivalent to a quantification condition. Keywords:non-differentiable entropy; informational non-differentiable entropy; informational non-differentiable energy; uncertainty relations Entropy 2014, 16 6043

“…Changes in tribological and mechanical behavior depend largely on the nature and size of metal compounds that are generally quite complex metal systems [9][10][11][12]. The scientific understanding of the friction phenomenon has advanced much on the basis of experimental results, but the complicated nature of brake friction involving very high energies, very high temperatures, very high speeds and pressures makes this process an inexact yet based on knowledge and power the understanding of the specialists [13][14][15][16][17][18][19].…”

Complex ceramic superficial ceramic layers (Al2O3, SiO2, YO, ZrO2) were obtained by atmospheric plasma deposition, industrial wide application method, on a metal support Fe-C (FC 250). The substrate was sandblasted mechanically prior to depositing 6 successive layers of ceramic material. The obtained layers were analyzed structurally (scanning electron microscopy, SEM), chemical (spectroscopy of X-ray, EDAX) and mechanically (scratch tests) to characterize the new compound material obtained (thin layer-substrate). It was observed from the experimental results that there was a relationship between the state of the surface of the substrate and the adhesion of the ceramic layers to the metal surface.
