13. A path-following driver/vehicle model with optimized lateral dynamic controller
Reduction in traffic congestion and overall number of accidents, especially within the last decade, can be attributed to the enormous progress in active safety. Vehicle path following control with the presence of driver commands can be regarded as one of the important issues in vehicle active safety systems development and more realistic explanation of vehic

14. Investigation on natural frequency of an optimized elliptical container using real-coded genetic algorithm
This study introduces a method based on real-coded genetic algorithm to design an elliptical shaped fuel tank. This method enhances the advantage of the system such as roll stability, and reduces disadvantages like fluid c.g. height and overturning moment. These parameters corresponding to the elliptical tanks with different filling levels are properly optim

15. A Multi-objective, active fuzzy force controller in control of flexible wiper system
Chaotic vibration has been identified in the flexible automotive wiper blade at certain wiping speeds. This irregular vibration not only decreases the wiping efficiency, but also degrades the driving comfort. A reliable nonlinear system identification namely nonlinear auto regressive exogenous Elman neural network (NARXENN) was adopted in first stage of this

16. An artificial neural network model for prediction of quality characteristics of apples during convective dehydration
In this study, the effects of hot-air drying conditions on color, water holding capacity, and total phenolic content of dried apple were investigated using artificial neural network as an intelligent modeling system. After that, a genetic algorithm was used to optimize the drying conditions. Apples were dried at different temperatures (40, 60, and 80 °C) an

17. PREDICCIÓN BAYESIANA DE PARÁMETROS GENÉTICOS EN CLONES DE Eucalyptus globulus BAJO CONDICIONES DE SUPLEMENTO HÍDRICO
ABSTRACT A Bayesian analysis of genetic parameters for growth traits at twelve months after planting was carried out in twenty nine Eucalyptus globulus clones in southern Chile. Two different environmental conditions were considered: 1) Non-irrigation and; 2) Plants were irrigated with a localized irrigation system. The Bayesian approach was performed using

18. Algoritmos para o planejamento da operação de sistemas modernos de distribuição de energia elétrica = : Algorithms for operation planning of modern electric distribution power systems / Algorithms for operation planning of modern electric distribution power systems
The distribution system operation planning stage is concerned with the determination of capacitor bank, transformer and voltage regulator settings. This must be accomplished considering active and reactive power injections of distributed generators and at the main substation, as well as physical and regulatory issues in order to improve the network performan

21. Estimador de variações de tensão de curta duração em sistemas elétricos de potência utilizando estratégias evolutivas. / Estimate short duration voltage variation using evolutionary strategies.
A methodology is herein proposed to estimate Short Duration Voltage Variation (SDVV) in electric power systems, caused by electrical faults. To attain this target, values recorded by measurement equipment in specific sites are used. In fact, there are few power quality meters installed in power networks, due to the high cost of such meters. Although these co

22. Sistema inteligente para alocação eficiente de dispositivos indicadores de falta em alimentadores de distribuição / An intelligent system for efficient allocation of fault indicators in distribution feeders
Fault Indicator (FIs) devices have contributed to improve the location of faults on primary feeders, and consequently the reliability of distribution systems. However, one of the main problems facing their installation in a large scale in a distribution system is the lack of efficient methods to analyze big networks and to pinpoint exactly on which buses the

23. Genetic Algorithm for the solution of majority problem / Algoritmo genÃtico para a soluÃÃo do problema da maioria.
Many natural and social systems exhibit globally organized behavior without the aid of a centralized control. Examples of such decentralized systems include conventions and norms, social learning in animals and humans, as well as fads, rumors and revolts. Examples are also abundant in biology: the evasive behavior of animals in large groups, such as fish and
