1. Preschool Students' Understanding of a Geometric Shape, the Square
Abstract The purpose of this study was to explore preschool children's conceptual understanding of geometric shapes, the square in particular. There were a total of 115 children, 61 girls and 54 boys, from state preschool education programs, who participated in the study. The data were collected in two semesters through interviews in a one-on-one setting, wh

2. DESENVOLVIMENTO DE METODOLOGIA DO PROJETO DO REATOR ELETRÔNICO AUTO-OSCILANTE COM ENTRADA UNIVERSAL / DEVELOPMENT OF METHODOLOGY OF SELF-OSCILLATING ELECTRONIC BALLAST DESIGN WITH UNIVERSAL INPUT
This work presents the design and analysis of an electronic system with universal input to supply a fluorescent lamp. The system includes a self-oscillating electronic ballast and an additional circuit which allows keeping the nominal lamp power although a variation of the input voltage. The electronic ballast design comprises some steps: resonant filter des

4. A novel approach based on multiple criteria decision aiding methods to cope with classification problems / A Novel Approach Based on Multiple Criteria Decision Aiding Methods to Cope with Classification Problems
This work presents a novel decision making approach developed upon two Multicriteria Decision Aiding (MCDA) classification methods. The classification methods are centered on the concept of prototypes, that are alternatives that serve as class representatives related to a given problem, and have their performance index very dependent upon the choice of value

5. SeleÃÃo de protÃtipos: combinando auto-geraÃÃo de protÃtipos e mistura de gaussianas
Prototype selection is a machine learning scheme in which the main purpose is to choose pattern vectors from the training dataset that achieve a better fit to data point distributions and maintain class separation. The aim of this kind of technique is to find the smallest possible prototype set that minimizes the classification error rate. Prototype-based st

6. Estudo comparativo entre metaheutísticas populacionais com tamanho da população variável
This work introduces four novel population-based heuristic algorithms, whose population size varies along the execution, which are aimed at solving problems of search and numerical optimization. These algorithms are extensions of the standard models of two metaheuristics recently proposed in the literature, which have been successfully applied in different f

9. Algoritmos OPWI e LDM-GA para sistemas de conversão texto-fala de alta qualidade empregando a tecnologia SCAUS / Algorithm OPWI and LDM-GA for high quality text-to-speech synthesis based on automatic unit selection
This Thesis presents two new algorithms for Unit Selection Based Text-to-Speech systems (USBTTS). The first algorithm is the OPWI (Optimized Prototype Waveform Interpolation), which was designed to be used as a Back-End module for USB-TTS. The second algorithm is the LDM-GA (Linguistic Data Mining Using Genetic AIgorithm), which was designed to minimize trai
