Mechanical Properties Evaluation of Eucalyptus grandis Wood at Three Different Heights by Impulse Excitation Technique (IET)
(North Carolina State Univ Dept Wood & Paper Sci, 2018-01-01)
Wood is a natural material with great variability in its mechanical properties. This study analyzed the effectiveness of the impulse excitation technique (IET) to characterize the stiffness of 10-year-old Eucalyptus grandis ...
On retarded differential equations with impulses
(Springer, 2001-01-01)
We are concerned with the effect of impulses in retarded functional differential equations. By using fixed point techniques we prove the existence of periodic solutions of some impulsive equations. For a system of retarded ...

A physical approach of the test voltage function for evaluation of the impulse parameters in lightning impulse voltages with superimposed oscillations and overshoots
(Institute of Electrical and Electronics Engineers, 2016-10)
The introduction of the test voltage function or k-factor in IEC 60060-1 Ed. 3 has been an important step to ensure reproducibility and traceability in high voltage tests techniques for lightning impulses with superposed ...

Source-sink impulsive bioeconomic models: Seasonal closures with fixed length
(2011)
The dynamics of four source-sink models for an exploited resource under a constant fishing effort are here presented. Two models are described by ordinary differential equations; the other two are expressed by impulsive ...

Maximization of the signal impulsiveness combining envelope technique with minimum entropy deconvolution
(2013-10-29)
The application of the HFRT (High-Frequency Resonance Technique), a demodulation based technique, is a technique for evaluation the condition of bearings and other components in rotating machinery. Another technique MED ...
