Fatigue crack growth of Al 7475 T761 under constant and variable amplitude loading
(Pergamon Press Ltd, 1997-01-01)
Experimental programs in constant and variable amplitude loading were performed to obtain a x N curves and to study retardation in fatigue crack growth due to overloads. The main aim of this research program was to analyse ...
A linearly-tunable OTA-C sinusoidal oscillator for low-voltage applications
(2002-01-01)
A low-voltage, low-power OTA-C sinusoidal oscillator based on a triode-MOSFET transconductor is here discussed. The classical quadrature model is employed and the transconductor inherent nonlinear characteristic with input ...

Scattering equations, generating functions and all massless five point tree amplitudes
(Springer, 2015-05-11)
We argue that one does not need to know the explicit solutions of the scattering equations in order to evaluate a given amplitude. We consider the most general quantity consistent with SL(2,C) invariance that can appear ...
Effect of amplitude and pulse in low frequency ultrasound on oil/water emulsionsEfecto de la amplitud y pulsación en ultrasonido de sonda a baja frecuencia sobre emulsiones aceite/agua
(DYNA, 2016)
The application of ultrasound within advanced or emerging technologies requires selecting parameters that depend on the target application. This study evaluated pulse and amplitude parameters of oil/water emulsions (20:80% ...
