Information systems play an ever-increasing key role in our society. In particular, data intensive applications are in constant demand and there is need of computing environments with much more intelligent capabilities t...

Previous research suggests that the inclusion of motivational strategies in interventions for intimate partner violence (IPV) offenders could increase their effectiveness. This review evaluated the effectiveness of inter...

In this work we will study the problem of the design of the "Integration Model for Distributed Database System". We particularly design the canonical model through the ontological handling of the information. The ontolog...

Este artigo tem por objetivo apresentar parte do estudo realizado sobre sintonia de performance de banco de dados que consiste em levantar e propor um conjunto de regras que melhore o desempenho de aplicações de banco ...

LabeledDeductive Systems (LDS)were developed as a rigorous but fexiblemethodology to formalize complex logical systems, such as temporal logics, database query languages and defeasible reasoning systems. LDSAR is a LDS-...

This paper describes two parallel algorithms for the eÆcient processing of relational database transactions and presents a performance analysis of them. These algorithms are built upon the bulk-synchronous parallel mode...

The tools for fault impact analysis are important for the deployment of critical mission systems. These tools can be also used as a development phase aid. We introduce several concepts related to "business alarms". Busin...

"Transportation networks (e.g., river systems or road net works) equipped with sensors that collect data for several different pur poses can be naturally modeled using graph databases. However, since networks can change ...

Nowadays, data intensive applications are in constant demand and there is need of computing environments with better intelligent capabilities than those present in today's Database Management Systems (DBMS). To build suc...

We present a new approach for iris recognition based on stochastic autoregressive models with exogenous input (ARX). Iris recognition is a method to identify persons, based on the analysis of the eye iris. A typical iri...

The term “Federated Databases” refers to the data integration of distributed, autonomous and heterogeneous databases. However, a federation can also include information systems, not only databases. When integrating d...

Labeled Deductive Systems (LDS) were developed as a rigorous but exible method- ology to formalize complex logical systems, such as temporal logics, database query languages and defeasible reasoning systems. LDSAR is a ...

En los últimos años las organizaciones aumentaron el uso de las tecnologías de la información, y también aumentaron los riesgos asociados a ellas. La complejidad de las infraestructuras que incluyen un gran número ...

Argumentation systems have substantially evolved in the past few years, resulting in adequate tools to model some forms of common sense reasoning. This has sprung a new set of argument-based applications in diverse are...

La búsqueda por similitud consiste en recuperar todos aquellos objetos dentro de una base de datos que sean parecidos o relevantes a una determinada consulta. Este concepto tiene una amplia gama de aplicaciones en área...

Inicialmente un grupo de desarrolladores de software enfrentaron el problema de disponer de una capa de software capaz de permitir el desarrollo ágil de aplicaciones Web, básicamente utilizando a PHP como lenguaje de t...

The interest in indexing and querying video data is growing rapidly. Desktop video is a new and attractive medium for communication between people using computers and networks. The main focus in any video information sys...

El análisis de imágenes puede revelar información útil para los usuarios El significativo aumento del uso de imágenes en diferentes campos de la ciencia, medicina, negocios, etc., requiere de mayor poder de procesam...

Com o aumento do uso de redes de computadores, aplicações que se utilizam de bancos de dados distribuídos crescem na mesma proporção em grandes corporações. Com isso, falhas de comunicação são detectadas com ma...

O processo de Descoberta de Conhecimento em Bancos de Dados Geográficos (DCBDG) busca encontrar padrões, informações e relacionamento espacial implícitos em dados descritivos e espaciais armazenados em bancos de dad...

This paper presents a new approach to reduce the space problem due to combinatorial explosion of CNM (Combinatorial Neural Model) method. First we show a description of CNM, proposed by Machado and Rocha [MAC 91], [MAC 9...
