Tunable optical filters using compound ring resonators for DWDM
(07/28/2003)
The device is based on a loop mirror in a ring resonator. The loop mirror allows tuning by changing the coupling coefficient of a directional coupler. The loop mirror is implemented using a Sagnac configuration to have the ...
Irrigation System Through Intelligent Agents Implemented With Arduino Technology
(11/01/2013)
The water has become in recent years a valuable and increasingly scarce. Its proper use in agriculture has demanded incorporate new technologies, mainly in the area of ICT. In this paper we present a smart irrigation system ...
Scene classification based on semantic labeling
(07/14/2015)
Finding an appropriate image representation is a crucial problem in robotics. This problem has been classically addressed by means of computer vision techniques, where local and global features are used. The selection ...
Demultiplexers for ultranarrow channel spacing based on Mach-Zehnders and ring resonators
(09/01/2004)
Novel demultiplexer configurations based on concatenated Mach-Zehnders and a ring resonator are presented. These new devices exhibit high channel isolation, flexibility, no loss, and megahertz-adjustable full width at half ...
Mathematical model for a temporal-bounded classifier in security environments
(08/01/2012)
Security is a major concern when web applications are implemented. This has led to the proposal of a variety of specifications and approaches to provide the necessary security for these environments. SQL injection attacks ...
