Novel tuneable filter based on MZ and an amplified ring resonator for OFDM networks
(1999-11-08)
A novel reconfigurable fibre based tuneable filter is proposed. The module relies on a cascaded connection of Mach-Zehnders and an amplified fibre ring resonator. MHz range adjustable FHWM bandwidths and high crosstalk are ...
idMAS-SQL: Intrusion Detection Based on MAS to Detect and Block SQL injection through data mining
(05/10/2013)
This study presents a multiagent architecture aimed at detecting SQL injection attacks, which are one of the most prevalent threats for modern databases. The proposed architecture is based on a hierarchical and distributed ...
Wide tunable filters using a recirculating delay line with multi-reflections
(05/01/2002)
A ring resonator with multiple reflections as a tunable filter is proposed and analyzed in this paper. A coupler and two identical Bragg gratings are used to implement the internal reflections so an active filter with a ...
A plastic fiber optic liquid level sensor
(06/09/2004)
A system for measuring liquid level in multiple tanks using optical fiber technology has been developed. Oil field service industry or any sector requiring liquid level measurements in inflammable atmospheres can be benefited ...
Low power consumption silicon photonics tuning filters based on compound microring resonators
(03/14/2013)
Scalable integrated optics platforms based on silicon-on-insulator allow to develop optics and electronics functions on the same chip. Developments in this area are fostered by its potential as an I/O technology that can ...
Sagnac loop in ring resonators for tunable optical filters
(08/01/2005)
General filter architecture using co-and counterpropagation signals are studied. A specific configuration based on a Sagnac loop within a ring resonator is analyzed. Novel tuning, apart from conventional tuning,is achieved ...
Systematic review and comparison of modeling ETL processes in data warehouse
(08/23/2010)
Abstract:
In a Data Warehouse (DW), ETL processes (Extraction, Transformation, Load) are responsible for extracting, transforming and loading data from the data sources into the DW. A good design of these processes in the ...
ICT: Improving processes in rural areas
(04/28/2016)
The Information and Communication Technologies (ICT) are the foundation for the Administration to achieve lower costs, streamline processes and provide better service to citizens; but above all they allow you to convert ...
Automatic generation of ETL processes from conceptual models
(11/06/2009)
Data warehouses (DW) integrate different data sources in order to give a multidimensional view of them to the decision-maker. To this aim, the ETL (Extraction, Transformation and Load) processes are responsible for extracting ...
Semi-supervised 3D object recognition through CNN labeling
(04/01/2018)
Despite the outstanding results of Convolutional Neural Networks (CNNs) in object recognition and classification, there are still some open problems to address when applying these solutions to real-world problems. Specifically, ...
