The goal of Lisbon Agenda is to make the EU "the most dynamic and competitive knowledge-based economy in the world, capable of sustainable economic growth improving skiels for more and better jobs and greater social ...

This paper presents a cumulative and comparative analysis, concerning the noise and vibration pollution and protective approaches, monutoring the construction technological equipments. By means of the computer simulations, ...

Today’s economic context allows corporations and their business environment to produce larger and larger amounts of data relying on the latest information. For the survival in actual complex and unpredictable environment, ...

Competitiveness fully and synthetically characterizes the viability of an enterprise. In the economics literature competitiveness is analyzed in particular in economic and managerial terms with almost no insight into the ...

Decreasing of sound and vibration global level inside and/or outside the public works equipment’s cabin as well as the reduction the noise pollution or the pollution accounted by the vibration and mechanical shocks on ...

The movements of many material systems can be described by differential equations that have coefficients that depend on time. It is difficult to determine the solutions of these equations. Although many concrete problems ...

Non-linear vibrations of mechanical systems are described by differential equations of the second order, which are generally written .. . x f ( x, x,t )  0 . In this work we study non-autonomous vibrations of mechanical ...

In this paper, competitiveness, will be understood as the capacity (potential) to provide performance (compared with other similar elements), in a very exact way, within a macroeconomic concrete context and at a certain ...

Due to this Fourier series exclusive interpretation applied to periodical signals, which shows that a stationary harmonic signal with a single pulsation  cannot contain components of other pulsations but its own pulsation ...

The paper analyzes the dynamic stresses induced by mechanical vibrations on an electronic circuit board, considering different study hypotheses, resulting from real cases presented in technical texts. The corresponding models ...
