1. Data mining as a hatchery process evaluation tool
ABSTRACT The hatchery is one of the most important segments of the poultry chain, and generates an abundance of data, which, when analyzed, allow for identifying critical points of the process . The aim of this study was to evaluate the applicability of the data mining technique to databases of egg incubation of broiler breeders and laying hen breeders. The

2. Multi-Attribute Evaluation and Selection of Broiler House for the Low Prevalence of Footpad Lesion
ABSTRACT Intensive broiler production requires large flock density, which compromises litter quality and increases the prevalence of footpad lesions. The present study aimed at comparing the incidence of footpad dermatitis of broilers reared in two different rearing environments. Data from two broiler houses were recorded during 42 d. Air temperature and rel

4. Oxidative stress and antioxidant response in a thermotolerant yeast
Abstract Stress tolerance is a key attribute that must be considered when using yeast cells for industrial applications. High temperature is one factor that can cause stress in yeast. High environmental temperature in particular may exert a natural selection pressure to evolve yeasts into thermotolerant strains. In the present study, three yeasts (Saccharomy

5. Decision model to control water losses in distribution networks
Abstract The losses in the urban water supply networks have become a growing concern. There are several alternatives for the quantification, detection and monitoring of water losses. However, in general, water companies have budgetary and other constraints that hinder implementation. Therefore, this paper presents a model to aid the selection of a subset of

6. Traditional Eastern Spanish varieties of tomato
Despite the importance of traditional varieties of tomato (Solanum lycopersicum L.) as sources of variation in breeding programs and varieties targeted to high-price quality markets that value their exceptional organoleptic quality, little is known regarding the structure of these materials at the morphological level. In this study, a collection of 166 popul

7. Explorando conjuntos de dados volumétricos multidimensionais variantes no tempo usando projeções / Exploring time-varying multidimensional volumetric datasets using projections
The area of volume visualization encompasses a set of techniques used for representation, manipulation and display of data associated with a region of a volume, thus enabling the exploration and understanding of the interior of three-dimensional objects. However, some limitations are still encountered in this area. For example, the simultaneous exploration o

9. PROJECT SELECTION PROCESS IN A POWER UTILITY FIRM IN BRAZIL USING MULTI-CRITERIA ANALYSIS / CLASSIFICAÇÃO DE PROJETOS EM DISTRIBUIDORAS DE ENERGIA ELÉTRICA NO BRASIL UTILIZANDO ANALISE DE DECISÃO MULTICRITÉRIO
The evaluation of a project and its economic and financial viability are frequently calculated using the discounted cash flow method. However, the fact that a project is financially feasible doesn´t necessarily means that it reflects the preferences of the stakeholders. Besides this, the discounted cash flow method isn´t capable of valuing projects with re

10. MoSAC: um módulo para seleção de configurações arquiteturais baseado em critérios de QoS no contexto de sistema distribuídos autoadaptativos
O processo para a escolha dos melhores componentes a serem usados na construção de sistemas tem se tornado cada vez mais complexo; isso se torna mais crítico quando precisamos considerar várias combinações de componentes a serem escolhidos no contexto de uma configuração arquitetural. Essa preocupação ocorre, principalmente, quando lidamos com sist

11. Integrating time series mining and fractals to discover patterns and extreme events in climate and remote sensing databases.
This thesis presents new methods based on fractal theory and data mining techniques to support agricultural monitoring in regional scale, specifically regions with sugar cane fields. This commodity greatly contributes to the Brazilian economy since it is a viable alternative to replace fossil fuels. Since climate influences the national agricultural producti

12. Um modelo para a seleção de n-gramas significativos e não redundantes em tarefas de mineração de textos.
Uma proposta completa para resolver o problema de selecionar automaticamente atributos não redundantes do tipo n-gramas é apresentada neste trabalho. Geralmente, o uso de n-gramas é um requisito para melhorar a interpretação subjetiva dos resultados em tarefas de mineração de textos, nesses casos, eles são estatisticamente gerados e selecionados.
