As the younger generation of born digital library users and even well-established scholars rely increasingly on Google, or its new products Google Scholar and Google Book, for information resource discovery and access, libraries are finding it increasingly difficult to ensure…

A genetically diverse population of Setaria sphacelata was developed at Gainesville, Florida by intercrossing the cultivars ?Narok?, ?Kazungula? and ?Solander? and a local persistent population. To determine heritability of traits that may improve setaria as a forage plant in Florida,…

O problema da resistência em nematódeos gastrintestinais de caprinos, associado ao crescente interesse por alternativas de controle, levou à investigação da ação de Azadirachta indica sobre estes parasitas. No teste in vitro observou-se a ação ovicida e larvicida de extratos…

This work develops a system to visualize the information for radar systems interfaces. It is a flexible, portable software system that allows to be used for radars that have different technologies and that is able to be adapted to the…

This work describes an inference mechanism applied to AliQAn Question Answering System for Spanish in open domain. AliQAn is based fundamentally on the use of syntactic patterns to identify the possible answers. An inference mechanism is applied to the questions…

This paper presents a proposal for an architecture that integrates knowledge discovery systems (automatic acquisition) and knowledge based systems (experts systems). This work formulates considerations over the viability of the implementation of this architecture according to the advance of the…

A natural inference mechanism is presented : the Black Box problem is transformed into a Dirichlet's problem on the closed cube. Then it is solved in closed polynomial form, together with a Mean-Value theorem and a Maximum Principle.A generalization to…

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 present paper poses a new method for computing the rotation of a ball in sport training situations, when the ball is approaching the goal line. The proposed method significantly reduces the hardware requirements associated to the capture, as well…

This paper discusses automatic mapping methods for
concurrent tasks to processors applying graph analysis for
the relation among tasks, in which processing and
communicating times are incorporated. Starting by an analysis in which processors are homogeneous and data transmission times…
