El presente artículo propone una prueba de concepto para la observación mediante técnicas de imagen multibanda de 63 pigmentos de referencia histórica (usados desde la Antigüedad hasta el siglo XX). La respuesta de estos pigmentos se ha documentado en var... see more

The design of circularly polarised multiband poly fractal boundary microstrip antenna is proposed and experimentally studied. Initially the two orthogonal sides of the square patch are replaced with different fractal curves for circular polarisation (CP) ... see more

En este artículo es empleada la forma normal de Smith de ciertas matrices para ofrecer otra caracterización de la sobreyectividad de autómatas celulares lineales unidimensionales con múltiples reglas local sobre el anillo ZN de los enteros módulo N = 2. E... see more

In recent years, the acquisition and analysis of multispectral data are gaining a growing interest and importance in agriculture.  On the other hand, new technologies are opening up for the possibility of developing and implementing sensors with rela... see more

This paper presents novel reduced size diagonal slot embedded Triangular Gasket fractal patch antenna for multiband wireless applications. The diagonal slot geometry is embedded in triangular patch antenna for initial size reduction of the basic cell and ... see more

One of the major challenges due to spectrum scarcity in modern wireless communication is on antenna design that can serve a non-contagious frequency spectrum. In this paper, wideband and multiband design approaches are proposed to produce antennas that ca... see more

Deforestration is one of the crucial issues in Indonesia because now Indonesia has world's highest deforestation rate. In other hand, multispectral image delivers a great source of data for studying spatial and temporal changeability of the environmental ... see more

This work describes the automatic picking of the P-phase arrivals of the 3*106 seismic registers originated during the TOMO-ETNA experiment. Air-gun shots produced by the vessel “Sarmiento de Gamboa” and contemporary passive seismicity occurring in the is... see more

Microstrip Antenna is widely developed and used in modern telecommunications equipment because of its advantages. Microstrip antenna is also used in 5G development which is expected to increase communication capacity and also be able to provide very large... see more
