Considering that the motions of the particles take place on fractals, a nondifferentiable mechanical model is built. Only if the spatial coordinates are fractal functions, the Galilean version of our model is obtained: the geodesics satisfy a Navier-Stokes-type of equation with an imaginary viscosity coefficient for a complex speed field or respectively, a Schrödinger-type of equation or hydrodynamic equations, in the case of irrotational movements. Moreover, in this approach, the analysis of the fractal fluid dynamics generates conductive properties in the case of movements synchronization both on differentiable and fractal scales, and convective properties in the absence of synchronization (e.g. laser ablation plasma is analyzed). On the other hand, if both the spatial and temporal coordinates are fractal functions, it results that, the geodesics satisfy a Klein-Gordon-type of equation on a Minkowskian manifold.

The accurate determination of atmospheric temperature with telemetric platforms is an active issue, one that can also be tackled with the aid of multifractal theory to extract fundamental behaviors of the lower atmosphere, which can then be used to facilitate such determinations. Thus, in the framework of the scale relativity theory, PBL dynamics are analyzed through the aid of a multifractal hydrodynamic scenario. Considering the PBL as a complex system that is assimilated to mathematical objects of a multifractal type, its various dynamics work as a multifractal tunnel effect. Such a treatment allows one to define both a multifractal atmospheric transparency coefficient and a multifractal atmospheric reflectance coefficient. These products are then employed to create theoretical temperature profiles, which lead to correspondences with real results obtained by radiometer data (RPG-HATPRO radiometer), with favorable results. Such methods could be further used and refined in future applications to efficiently produce atmospheric temperature theoretical profiles.

One of the major functions of management, it is the foresight and management of action, in terms of knowledge of risks. In practical decision problems, the decision maker-the manager, is forced to make decisions in conditions of approximate partial knowledge of data necessary to determine the exact consequences of the decision. After the decision is taken, some uncertainty (uncertainty) remains, regarding achieve expected results.The practical application, carried out in S.C. "Mecanica Ceahlău" S.A, aims to demonstrate the complexity of risks categories faced by an organization operating in the manufacturing sector. The paper also illustrates how you can apply different methods to identify and analyze the risks, providing decision makers a comprehensive study and useful for maximizing the value of the organization.
