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…

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…

The metric spaces model formalizes the similarity search concept in nontraditional databases. The goal is to build an index designed to save distance computations when answering similarity queries later. A large class of algorithms to build the index are based…

Se realizó el estudio termoanalítico del atenolol puro y de comprimidos comerciales utilizando técnicas de termogravimetría (TG) y calorimetría diferencial de barrido (DSC). El método no isotérmico fue empleado para determinar los datos cinéticos del proceso de descomposición. Para evaluar…

In situ hybridization (ISH) method allows to reveal specific genes expression, identify specific cell types and detect areas or tissues, displaying differential gene expression. This work describes a standardized procedure of digital image processing that allows detailed analyses of ISH…

Durante la preparación de la selección junior autonómica de remo (Comunidad Valenciana, España), se recogieron las características antropométricas de 18 remeros junior masculinos de edad 17,83±3,83 años. A los remeros se le realizaron una valoración anthropometry mediante la técnica basadas…

En las áreas destinadas al procesamiento sistematizado de datos se encuentra instalados equipos de cómputo y auxiliares necesarios para realizar una función particular del proceso de información. Esas máquinas generan calor y contienen elementos sensitivos a condiciones externas de temperatura,…

Cuando se presenta una falla en un componente mecánico, de alguna manera, la carga aplicada se hace igual o mayor a la carga de falla en el momento que esta se produce. Teniendo en cuenta este principio y considerando la…

THE CONSTRUCTION OF MAPS OF SOCIAL NETWORKS IS SHOWN BASED IN THE JOURNAL OF DOCUMENTATION DURING THE PERIOD 1988-2005. THE ANALYSIS IS MADE BY: (I) AUTHORS THAT PRODUCE THE MOST WITHIN THE PUBLICATION, (II) AUTHORS WITH THE GREATEST CENTRALITY AND…
