An Evaluative Study of the Competitive Management
(Universitatea "Dunărea de Jos" din Galați, 2010)
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 ...
About Signals' Spectrum
(Universitatea "Dunărea de Jos" din Galați, 2010)
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 ...
Considertions on the Mechanical Vibrations of an Electronic Circuit Board
(Universitatea "Dunărea de Jos" din Galați, 2010)
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 ...

This paper aims to present synthetically as many of those tools that are part of
Mechanical Desktop 2008 software with notable performance in the CAD
environment and to justify this performance by the presentation of the ...
Filter Signals a First Step in Interpreting Experimental Results
(Universitatea "Dunăread de Jos" din Galați, 2010)
After recording and storage of experimental data, a first step in their
processing is filtering, ie, removal of parasitic components (noise)
accompanying the signal due from other machines or equipment in service
or ...
The Emfi Material and their Use
(Universitatea "Dunărea de jos" din Galați, 2010)
ElectroMechanical Film (EMFi) is a thin, plastic material that can be
utilized as a sensor and actuator. EMFi is quite new material in the field of
ultrasonics and has favorable properties like good matching to air ...

resonator ...
Assembly Modeling Using Catia System
(Universitatea "Dunărea de Jos" din Galați, 2010)
CATIA is one of the most performance graphics programs that has been created for the
production of technical drawings in the 2d and 3d with a high precision. In this paper, we
have presented a simple assembly that is a ...
Optimazation of Ultrasonic Flow Meters for Crude Oil Metering and Export
(Univeritatea "Dunărea de jos" din Galați, 2012)
Ultrasonic flow meters, as all velocity or inference type devices, require
an adequate flow stream conditioning in order to assure an accurate
performance. Typical flow conditioning consists of straightening the
upstream ...
