26. Genetic diversity among red mombin fruits in the Southwest of Goiás
ABSTRACT The identification of productive plants with fruits of desirable characteristics contributes to the optimization of commercial crops of red mombin fruits. The aim of this work was to evaluate the genetic diversity among the provenance of red mombin of two municipalities of the state of Goiás. The fruits were harvested at ripening stage 3 and transp

27. Otimização Mono-objetivo no Controle do Mosquito Aedes aegypti por meio de um Modelo de Duas Populações com Influência da Precipitação
RESUMO Arboviroses transmitidas pelo Aedes aegypti como a dengue, a chikungunya, a zika e a febre amarela têm afetado uma parte crescente da população mundial ao longo dos anos. Uma vez que não existem vacinas para todos os arbovírus transmitidos por este vetor, o controle da população do vetor é a abordagem considerada viável para reduzir a dissemi

28. Determination of Barreling of Aluminum Solid Cylinders During Cold Upsetting Using Genetic Algorithm
ABSTRACT This study presents Genetic Programming models for the formulation of barreling of aluminum solid cylinders during cold upsetting based on experimental results. The maximum and minimum radii of the barreled cylinders having different aspect ratio (d/h= 0.5, 1.0 and 2.0) were measured for various frictional conditions (m=0.1-0.4). The change in radii

29. Agronomic performance and genetic dissimilarity of second-harvest soybean cultivars using REML/BLUP and Gower’s algorithm
ABSTRACT The cultivation of second-harvest with soybean crop after first-harvest with maize crop has become an alternative to aggregate income to farmers in the South region of Brazil. However, there is little information about this cropping system in this region. The aims of this study were to: (i) evaluate the agronomic performance of soybean (Glycine max

30. Multi-Objective Cooperative Paths Planning for Multiple Parafoils System Using a Genetic Algorithm
ABSTRACT In large-scale natural disasters and military supplies, multiple parafoils are more capable of performing actual tasks. The cooperative paths planning for multiple parafoils with different initial positions and headings is an important step in multiple parafoils airdrop, which has to satisfy multiple objectives, namely, parafoils can’t collide wit

31. Analysis of sensor placement in beams for crack identification
Abstract A previous study has shown that the mode shapes of a beam are more sensitive to damage than other vibrational parameters, thus making them better suited for crack identification purposes. However, they have the disadvantage of being more difficult to be measured. To overcome this difficulty, an interesting idea is to monitor changes produced by crac

32. SSR-based genetic analysis of sweet corn inbred lines using artificial neural networks
Abstract Studies on genetic diversity and population structure provide basic information at the molecular level, which is a key input for breeding programs of crop species. This study evaluated the genetic diversity of 12 elite lines of sweet corn, using 20 microsatellite markers. To determine the genetic differentiation among lines, we used an artificial ne

35. Multi-objective Optimization Method For Repeat Ground-track Orbit Design Considering the Orbit Injection Error
ABSTRACT: Considering the adverse effects of orbit injection error, a novel repeat ground-track orbit redesign approach is proposed to reduce the fuel consumption caused by the orbital maneuvering from the injection orbit to the nominal orbit. By introducing the performance indexes of revisiting accuracy and orbit injection maneuvering fuel consumption, the

36. Photoacoustic-based thermal image formation and optimization using an evolutionary genetic algorithm
Abstract Introduction For improved efficiency and security in heat application during hyperthermia, it is important to monitor tissue temperature during treatments. Photoacoustic (PA) pressure wave amplitude has a temperature dependence given by the Gruenesein parameter. Consequently, changes in PA signal amplitude carry information about temperature varia
