Modelling ETL processes of data warehouses with UML activity diagrams
(11/09/2008)
Extraction-transformation-loading (ETL) processes play an important role in a data warehouse (DW) architecture because they are responsible of integrating data from heterogeneous data sources into the DW repository. ...
Preparación de Películas de Óxidos de Estaño Como Sensores de Gases
(2009-06)
Se obtuvieron películas delgadas de Óxido de Estaño (SnO2) por el método de química líquida a partir de una solución precursora de Cloruro de Estaño IV (SnCl4). Las muestras fueron depositadas sobre sustrato de vidrio ...

Se estudió la germinación de semillas de Bulnesia retama frente a condiciones de estrés hídrico, simulado con PEG6000 a distintas temperaturas, y su recuperación ante el estrés. Las semillas recolectadas en San Luis ...
A numerical study of parameters governing an inherent deformation database of plates formed by line heating
(2008-08)
As an overall strategy to improve the accuracy of the forming process, the authors pay attention to those factors which may influence the inherent deformation of plates formed by line heating. In order to identify those ...
Outer Factor 2-D MA Models for Purely Random Fields and Fields and Wold-Tipe Texture Decompositions
(2007-06-29)
In this paper, we propose a new method to compute the parameters of finite approximations of 2-D MA infinite models associated with purely indeterministic stationary fields, by using spectral factorizations. This method ...
Towards Simple Interaction in the Classroom: an NFC Approach
(2008-06-30)
In a given environment, distributing different devices with computing capabilities around us opens up new possibilities. It allows simple and easy interaction between user and computer. In this work we propose an approach ...
Classification Agent-Based Techniques for Detecting Intrusions in Databases
(09/24/2008)
This paper presents an agent specially designed for the prevention and detection of SQL injection at the database layer of an application. The agent incorporates a Case-based reasoning mechanism whose main characteristic ...
