LCA methodology is often used in public procurement decision making. The European Commission introduced Life Cycle Costing (LCC) in 2014 to support this methodology. LCCs take into account costs incurred during a service, work or product’s lifetime. Application management techniques of LCC offer a better awareness of the factors that influence the resources and costs in the case of procurements. The identification of the factors that influence the costs is the main key of the LCC tool. In such a way, the life cycle management is focused on efficient purchasing. The awareness levels of the LCC criteria influence the cost and will also highlight other aspects of existing products that could benefit from the involvement of life cycle management. Taxi transport services (as an alternative to public transportation) are a sector of the economy with a good income when acquisitions are properly carried out. When the acquisitions are analyzed, governmental and local regularizations should be taken into account. Today, cities, as well as small towns, look forward to improving the quality of life of the citizens and reducing pollution. The acquisitions of buses/cars for public use must be carried out with respect to the required performance of the cars. On the one hand, the municipality should be in line with the European Commission’s policy; on the other hand, it should be in line with the state’s public procurement requirements. An acquisition must also be reasonable in terms of price, lifetime, environmental impact, circular economy and meeting citizens’ needs. The goal of this paper was to analyze the acquisition of cars for taxi services from the perspective of public procurements. The study was performed with the help of the Taxi LAL company from Bacau County. The LCC techniques were applied to identify the most “acceptable” as well as the most “profitable” choices for taxi services. For a better understanding of the problem, within the present paper the mechanism of cost assessment for a product modernization was exemplified.

In this paper, a practical application of theoretical developments found in our previous works is explored in relation to atmospheric lidar data. Multifractal structures, previously named “laminar channels”, have been identified in atmospheric profiles—these exhibit cellular and self-structuring properties, and are spatially ordered across the atmospheric profile. Furthermore, these structures have been connected to the spontaneous emergence of turbulent behavior in the calm atmospheric flow. Calculating the location and occurrence of these channels can help identify features of atmospheric evolution, such as the development of the planetary boundary layer (PBL). Employing this theoretical background to atmospheric lidar data, attempts are made to confirm this suggestion and extract information about atmospheric structure and evolution by analyzing turbulent vortex scale dynamics and scale-corresponding Lyapunov exponents that form the basis of identifying the laminar channels in atmospheric lidar profiles. A parameter named “scale laminarity index” is then introduced, which quantifies the relation between vortex scale and chaoticity throughout the profile. Finally, the algorithmic methods employed in this study are described and distributed for future use.

In the framework of the multifractal hydrodynamic model, the correlations informational entropy–cross-entropy manages attractive and repulsive interactions through a multifractal specific potential. The classical dynamics associated with them imply Hubble-type effects, Galilei-type effects, and dependences of interaction constants with multifractal degrees at various scale resolutions, while the insertion of the relativistic amendments in the same dynamics imply multifractal transformations of a generalized Lorentz-type, multifractal metrics invariant to these transformations, and an estimation of the dimension of the multifractal Universe. In such a context, some correspondences with standard cosmologies are analyzed. Since the same types of interactions can also be obtained as harmonics mapping between the usual space and the hyperbolic plane, two measures with uniform and non-uniform temporal flows become functional, temporal measures analogous with Milne’s temporal measures in a more general manner. This work furthers the analysis published recently by our group in “Towards Interactions through Information in a Multifractal Paradigm”.
