Improved Nyquist-I Pulses to Enhance the Performance of OFDM-Based Systems
(Springer, 2017)
Pulse shaping is used in orthogonal frequency division multiplexing (OFDM) based systems to reduce inter-carrier interference (ICI) power and peak-to-average power ratio (PAPR), which are considered the major weaknesses ...
Identification of High Frequency Pulses from Earthquake Asperities Along Chilean Subduction Zone Using Strong Motion
(2011)
The Chilean subduction zone is one of the most
active of the world with M = 8 or larger interplate thrust earthquakes
occurring every 10 years or so on the average. The
identification and characterization of pulses ...
Fabrication of novel shape Cu and Cu/Cu2O nanoparticles modified electrode for the determination of dopamine and paracetamol
(2016)
In this paper, we demonstrate and compare the synthesis of copper (Cu) and copper(I) oxide on Cu (Cu/Cu2O) nanoparticles via thermal decomposition method using a combination of oleic acid and oleylamine and oleic acid ...
Caracterización de electrorecubrimientos cobre-níquel sobre substratos de zamak utilizando corrientes pulsantes con y sin inversión de polaridad
(Universidad Distrital Francisco José de CaldasColombia, 2006)
Este trabajo muestra el análisis de algunas propiedades de los electrorecubrimientos cobre-níquel, depositados sobre substratos de Zamak que fueron obtenidos con la técnica de Corriente Directa Convencional (DC) y comparados ...
Assessing the role of bitumen in the formation of stratabound Cu-(Ag) deposits: Insights from the Lorena deposit, Las Luces district, northern Chile
(Elsevier, 2020)
Stratabound Cu-(Ag) deposits located in north-central Chile have been grouped into two NS parallel belts according to the age of their volcanic and volcanoclastic host rocks. Deposits from the Cretaceous belt are characterized ...

Corrosion-erosion effect on TiN/TiAlN multilayers
(Springer, 2011-12-16)
The goal of this work is to study electrochemical behavior under corrosion-erosion conditions for [TiN/ TiAlN]n multilayer coatings with bilayer number (n) of 2, 6, 12, and 24 and/or bilayer period (K) of 1500, 500, 250, ...
Erbium ring fiber laser cavity based on tip modal interferometer and its tunable multi-wavelength response for refractive index and temperature
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-08-10)
A tunable multi-wavelength fiber laser is proposed and demonstrated based on two main elements: an erbium-doped fiber ring cavity and compact intermodal fiber structure. The modal fiber interferometer is fabricated using ...
Cuarta revolución industrial: implicaciones en la seguridad internacional
