1. A Genetic Algorithm for Pointwise Source Reconstruction by the Method of Fundamental Solutions
ABSTRACT Inverse source reconstruction problems offer great potential for applications of interest to engineering, such as the identification of polluting sources, and to medicine, such as electroencephalography, to cite at least two relevant examples. From a mathematical point of view, the identification of a concentrated source (intensity and location) cor

2. A QUANTITATIVE EVALUATION OF DGPS PERFORMANCE IN THE POSITION AND PSEUDORANGE DOMAINS
Abstract: This study compares in quantitative terms two methods of differential corrections to GPS positioning from the code-based pseudoranges. The differential method calculated from the coordinates (Latitude, Longitude and Altitude), called Position-Domain DGPS, has simple implementation and easy transmission by the correction vector. The second method, c

3. Optimal pressure management in water distribution networks through district metered area creation based on machine learning
RESUMO A gestão integrada dos sistemas de abastecimento de água com o uso eficiente dos recursos requer a otimização das operações. O agrupamento das redes de abastecimento de água em pequenas unidades, chamadas de distritos de medição (DMAs), é uma estratégia que permite o desenvolvimento de regras operacionais específicas, responsáveis por mel

4. Procedimentos para análise e validação de atributos da qualidade da água
RESUMO O tratamento incorreto de efluentes líquidos, assim como o seu lançamento inadequado, caracterizam algumas das maiores problemáticas ambientais e pode contribuir para a deterioração dos ecossistemas aquáticos. Nesse contexto, a utilização de modelos de predição possibilita, especialmente no caso de volumes, a observação do comportamento do

5. As Regiões de Saúde no Brasil segundo internações: método para apoio na regionalização de saúde
Este estudo aborda as regionalizações da saúde em várias escalas espaciais com base no fluxo de pacientes. Para isso, foram analisados dados por meio do relacionamento das informações de origem e destino das interações realizadas em nível municipal no Brasil em 2016. A análise tem como base a teoria dos grafos e utiliza um algoritmo de modularidade

6. Application of SAC-SMA and IPH II hydrological models in the Teles Pires River basin, Brazil
RESUMO A parametrização e a análise do desempenho de um modelo hidrológico permitem sua consolidação para avaliação de estratégias de gerenciamento de recursos hídricos e para previsão de eventos extremos. Nesse contexto, o objetivo do trabalho foi avaliar o desempenho dos modelos chuva-vazão Soil Moisture Accounting (SAC-SMA) e IPH II para pred

7. Comparison of predictive performance of data mining algorithms in predicting body weight in Mengali rams of Pakistan
ABSTRACT The present study aimed at comparing predictive performance of some data mining algorithms (CART, CHAID, Exhaustive CHAID, MARS, MLP, and RBF) in biometrical data of Mengali rams. To compare the predictive capability of the algorithms, the biometrical data regarding body (body length, withers height, and heart girth) and testicular (testicular lengt

8. Yeast fermentation of sugarcane for ethanol production: Can it be monitored by using in situ microscopy?
ABSTRACT This paper addresses some key issues related to the automation of fermentation process analysis in the context of industrial-scale ethanol production from sugarcane substrates. As the current methods for the determination of cell density and viability are time consuming and laborious, high resolution in situ microscopy (0.5µm) is proposed as a prom

9. COMPUTING MAX FLOWS THROUGH CUT NODES
ABSTRACT In this work, the presence of cut nodes in a network is exploited to propose a competitive method for the multi-terminal maximum flow problem. The main idea of the method is based on the relation between cut-trees and cut nodes, which is observed in the context of sensitivity analysis on the variation of edges capacities. Computational experiments w

10. Development and application of an automatic tool for the selection of control variables based on the self-optimizing control methodology
Abstract Rules for control structure design for industrial processes have been extensively proposed in the literature. Some model-based methodologies have a sound mathematical basis, such as the self-optimizing control technology. The procedure can be applied with the aid of available commercial simulators, e.g., PRO/IITM and AspenPlus®, from which the conv

11. Hydrological Modeling of Tributaries of Cantareira System, Southeast Brazil, with the Swat Model
ABSTRACT The lack of hydrological data in Brazil is the main limitation for structuring hydrological models, which are able to assist water resources management. Therefore, studies are needed to evaluate the performance of models without on-site calibration. Within this context, the aim of this study was to calibrate the SWAT hydrological model for the Caman

12. Robust Multi-objective Optimization Applied to Engineering Systems Design
Abstract In engineering systems design, theoretical deterministic solutions can be hardly applied directly to real-world scenarios. Basically, this is due to manufacturing limitations and environmental conditions under which the real system will operate. Therefore, a small variation in the design variables vector can result in a meaningful change on the theo
