As a contribution to consider software projects to be risk investments, it is important the full standardization of either the planning methodology (as a subset of project management methodology) and the effort estimation method. We think there is important and…

Presentamos una estrategia para acelerar la simulación y visualización de mezclado advectivo--difusivo de un contaminante dentro de una cavidad cuadrada con condiciones de frontera dependientes del tiempo. No se requieren paredes móviles para mezclar el fluido sino la convección natural…

We can make very sensitive machines and may arrange for them to distinguish themselves from other objects. The programs that are designed toward specific goals, such as the identification of external objects, can also be imagined as action programs relating…

Vertical partitioning, in which attributes of a relation are
assigned to partitions, is aimed at improving database
performance. We extend previous research that is based on
a single relation to multi-relation database environment,
by including referential integrity constraints, access time

This paper is an attempt to define how a
specific data structure might be used to
store, in a persistent manner, temporal
information during a computer simulation.
In particular, it considers the sort of
temporal information generated during a
discrete…

Proponemos un modelo de interdependencia general lineal para la economía mundial, y utilizamos datos de la División Estadística de las Naciones Unidas para estimar sus parámetros. Esto nos permite evaluar la propagación de un shock exógeno a los gastos autónomos…

El objetivo de este artículo es examinar la relación existente entre la volatilidad de la tasa de cambio y el volumen de exportaciones, usando datos brasileños. Después de establecer la existencia de cointegración entre las variables incluidas en nuestro modelo,…

Este trabajo tiene como objetivo estimar la forma reducida de una función de oferta agropecuaria de la economía argentina en el marco de un modelo de equilibrio general. Los resultados de la estimación de la oferta agropecuaria con datos que…

This paper presents a data structure based on Sparse Spatial Selection (SSS) for similarity searching. An algorithm that tries periodically to adjust pivots to the use of database index is presented. This index is dynamic. In this way, it is…

Similarity search is a fundamental operation for applications that deal with unstructured data sources. In this paper we propose a new pivot-based method for similarity search, called Sparse Spatial Selection (SSS).
The main characteristic of this method is that it…
