Non-linearities in the Rod and Cone Photoreceptor Inputs to the Afferent Pupil Light Response
(Frontiers Media SA, 2018-12)
Purpose: To assess the nature and extent of non-linear processes in pupil responses using rod- and cone-isolating visual beat stimuli. Methods: A four-primary photostimulating method based on the principle of silent ...
The role of fast frequency response of energy storage systems and renewables for ensuring frequency stability in future low-inertia power systems
(MDPI, 2021)
Renewable generation technologies are rapidly penetrating electrical power systems, which challenge frequency stability, especially in power systems with low inertia. To prevent future instabilities, this issue should ...
Biomechanics and biotensegrity : study method and frequency response of the simplex and 3- bar-SVD tensegrity configurations
(IOP Publishing, 2016)
Abstract: The purpose of this work is to study the frequency response of 3D tensegrity structures. These are structures that have been used, since the 80’s, to model biological systems of different scales. This fact led ...
Dynamic analysis of a new piezoelectric flextensional actuator using the J1-J4 optical interferometric method
(2005-12-01)
Piezoelectric actuators are widely used in positioning systems which demand high resolution such as scanning microscopy, fast mirror scanners, vibration cancellation, cell manipulation, etc. In this work a piezoelectric ...

Evaluation of low-frequency voltage dividers, using the step response
(IEEE, 1998)
A method to characterize the behavior of low frequency voltage dividers, based on the step response, is presented. Amplitude errors and phase displacements can be evaluated, in an absolute way, without any auxiliary standard ...
Power Transformer Diagnosis Using FRA and Fuzzy Sets
(Institute Of Electrical And Electronics Engineers, 2015-09)
This paper presents a novel method for failure detection and interpretation in power transformers using Frequency Response Analysis (FRA). Mathematical indexes are used for failure detection. The performance of the most ...
