Validation of CHIRPS precipitation dataset along the Central Andes of Argentina
(Elsevier Science Inc, 2018-11)
A validation covering a 30-year period (1987–2016) of the relatively new CHIRPS precipitation dataset was performed over the Central Andes of Argentina (CAA), a semi-arid region with complex topography and sparse ground ...
Using CHIRPS Dataset to Assess Wet and Dry Conditions along the Semiarid Central-Western Argentina
(Hindawi Publishing Corporation, 2019-04)
The Climate Hazards group Infrared Precipitation with Stations (CHIRPS) dataset was conceived as a tool for monitoring drought and environmental change over land. Recent validation efforts along South America have assessed ...

Asymmetric multiple-image encryption system based on a chirp z-transform
(Optical Society of America, 2019-07)
An asymmetric multi-image encryption system based on the chirp z-transform (CZT) is demonstrated. The setup is a hybrid architecture that combines a double-random-phase encryption scheme in 4f configuration and a multiplexing ...
Dynamic multiple-image encryption based on chirp z-transform
(IOP Publishing, 2019-02)
It is demonstrated a dynamic encryption scheme based on chirp − z transform (CZT). The novel design of this setup allows to protect multiple images in a multiplexed format and fully recover them without the influence of ...
Positive and negative linear chirping of Gaussian pulses in non-dispersive dielectric layers
(Elsevier Science, 2020-11)
In this work, the first and second order effects for reflected and transmitted pulses with a Gaussian distribution of frequencies are analytically developed and interpreted. They show some peculiar characteristics that ...
