rise time

[′rīz ‚tīm]
(control systems)
The time it takes for the output of a system to change from a specified small percentage (usually 5 or 10) of its steady-state increment to a specified large percentage (usually 90 or 95).
(electricity)
The time for the pointer of an electrical instrument to make 90% of the change to its final value when electric power suddenly is applied from a source whose impedance is high enough that it does not affect damping.

The pulse has a risetime between 5 ms and 10 ms and a much longer fall time.
This region is populated only by crevice events, and it could be identified as the region of hydrogen evolution bubbling, as the value of Risetime (the higher ones) and values of Duration (the lower ones) suggest us [14].
Integrated compact current drivers provide fast risetime (5 [micro]sec) pulses above 1 kA/channel, relieving users from the challenge of providing high-current pulses.

Cuestiones como las anteriores nos hacen pensar que, previsiblemente, la eleccion de otros sonidos semejantes a los presentados para modular el reflejo de sobresalto (el mas frecuente ha sido un ruido blanco de 50ms, con risetime instantaneo y 95dB de intensidad), tonos como los de los concursos asociados a ejecuciones correctas/incorrectas, verbalizaciones que puedan atribuirse a la propia ejecucion pero que sean incontrolables desde el punto de vista objetivo, o algunos sonidos tambien relevantes desde el punto de vista evolutivo pero mas afines a la poblacion de ansiedad en concreto, como latidos cardiacos acelerados (similares a los utilizados por Pollock, Carter, Amir, y Marks, 2006), nos permitiria conocer mejor la funcionalidad de la red de alerta.
