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 ... -
All-Purpose Low Frequency Numerical Filter
(Universitatea "Dunărea de Jos" din Galați, 2007)A real signal is a complex system with mixed components. In addition to needed components appear unusable components with different origin, namely noise. The clearance or the reduction of the unwanted components is ... -
A Model of the Mechanical Waves in Curved Bars
(Universitatea "Dunărea de Jos" din Galați, 2007)The different classical models of the mechanical waves in bars cover every a single type of the wave, respectively only longitudinal, transversal, inflexion or torsion wave and only in a rectilinear bar, every with his ... -
On the Rheological Behaviour of the soil in the Artificial Compacting Process
(Universitatea "Dunărea de Jos" din Galați, 2008)The artificial compacting of the soil is made mostly with machines with dynamical action such as vibrating plate, vibrating beater or vibrating drum. Their effect on the compacting process of the soil has two origins: the ... -
The Approximate Analytical Solutions for the Differential Equations which Desccribe Free Vibrations of Non-Linear Mechanical Systems
(Universitatea "Dunărea de Jos' din Galați, 2006)The oscillation movement of a mechanical non-linear system is not easy to solve exactly on analytical way. The approximate solutions are based on different methods and give different values with different approximation degree. ...
