1. ANÁLISE MULTIVARIADA DE IMAGENS NA QUÍMICA: UM EXPERIMENTO PARA DETERMINAÇÃO DO pH DE ÁGUAS POTÁVEIS
A Multivariate Image Analysis (MIA) laboratory activity was proposed estimating pH of drinking water samples from its digital images after adding bromothymol blue as a pH indicator, and using the PLS multivariate calibration method. All computational work was done using GNU Octave free software. The MIA-PLS based approach exemplified with drinking water p

2. Proposta de sistema de busca de jogos eletrônicos pautada em ontologia e semântica
With the constant growth in the quantity of websites, and consequently the increase in content availability throughout the Internet, the development of search mechanisms that enable access to reliable information has become a complex activity. In this sense, this work presents a revision on the behavior of search mechanisms, as well as the manner through whi

3. PEHS: ARQUITETURA DE UM SISTEMA ELETRÔNICO DE SAÚDE PERVASIVO ORIENTADO ÀS ATIVIDADES DO USUÁRIO CLÍNICO
In despite of the great advantages of adopting computer systems for storing patient s information in hospitals and clinics, such systems are adopted with restrictions in these institutions. Some studies indicate that the rejection of such systems by the clinicians is greats due to computing not consider the particularities of the activities performed by the

4. Ferramenta para acompanhamento do processo de ensino-aprendizagem de programação de computadores utilizando o método de aprendizagem por competências
The learning of computer programming is fundamental in the formation of a computing professional. However, its learning is difficult and longlife, considering that every day new languages and environments appear in the labor market. In the Computer Science courses, many students have difficulties programming, the activity requires the learning of complex con

5. THE LIMITS OF INTELLECTUAL SUBSUMPTION LABOUR IN SOFTWARE PRODUCTION PROCESS / OS LIMITES DA SUBSUNÇÃO DO TRABALHO INTELECTUAL NO PROCESSO PRODUTIVO DE SOFTWARE
The principle of modern production is to combine modern production techniques, new knowledge, combined with increasingly sophisticated computerized development processes to increase production and processing continuous model itself. The Third Industrial Revolution, characterized by extreme specialization of intellectual labor and tendency to erase the border

6. SOLVING THE BIDOMAIN EQUATIONS USING GRAPHICS PROCESSING UNITS / Solução das Equações do Bidomínio em Processadores Grácos
The computational modelling of the heart has shown to be a very useful tool in the functional bioinformatics eld. The models, becoming more realistic each day, provide a better understanding of the complex biophysical processes related to the electrical activity in the heart as in the case of cardiac arrhythmias. However, the increasing complexity of the mod

7. A STUDY ON FRAUDSTER IDENTIFICATION IN ELECTRONIC MARKETS THROUGH HUMAN COMPUTATION / UM ESTUDO DE IDENTIFICAÇÃO DE FRAUDADORES EM MERCADOS ELETRÔNICOS ATRAVÉS DA COMPUTAÇÃO HUMANA
Fraudulent behavior is an increasing problem for electronic markets, in particular for online auction sites, causing several types of loss. Fraud loss reduction measures generally have as an undesirable by-product the harassment and even exclusion of bona fide users, creating a difficult trade- off between losses with fraudsters and losses due to excessive c

8. Software maintenance: typical problems and guidelines for a specific discipline / Manutenção de Software: problemas típicos e diretrizes para uma disciplina específica
The increasing volume of software being used in all types of organizations has been calling attention for a phase of the software life cycle, until now considered in a secondary way, the software maintenance. Since it is generally not possible to replace all software products used in an organization by others based on more recent technologies, the maintenanc

10. siDirect: highly effective, target-specific siRNA design software for mammalian RNA interference
siDirect (http://design.RNAi.jp/) is a web-based online software system for computing highly effective small interfering RNA (siRNA) sequences with maximum target-specificity for mammalian RNA interference (RNAi). Highly effective siRNA sequences are selected using novel guidelines that were established through an extensive study of the relationship between

11. Non-coding RNAs: the architects of eukaryotic complexity
Around 98% of all transcriptional output in humans is non-coding RNA. RNA-mediated gene regulation is widespread in higher eukaryotes and complex genetic phenomena like RNA interference, co-suppression, transgene silencing, imprinting, methylation, and possibly position-effect variegation and transvection, all involve intersecting pathways based on or connec

12. Place cell discharge is extremely variable during individual passes of the rat through the firing field
The idea that the rat hippocampus stores a map of space is based on the existence of “place cells” that show “location-specific” firing. The discharge of place cells is confined with remarkable precision to a cell-specific part of the environment called the cell’s “firing field.” We demonstrate here that firing is not nearly as reliable in
