In this paper, a nonlinear offline model of the solid oxide fuel cell (SOFC) is built by using a radial basis function (RBF) neural network based n a genetic algorithm (GA). During the process of modeling, the GA aims to optimize the parameters of RBF neural networks and the optimum alues are regarded as the initial values of the RBF neural network parameters. Furthermore, we utilize the gradie...

BACKGROUND Genetic background partly determines the efficacy of interventions to lower blood pressure (BP). The CYP4F2 and CYP4A11 enzymes are renal 20-hydroxyeicosatetraenoic acid (20-HETE) synthases that regulate BP. Gene variants of CYP4F2 and CYP4A11 associate with hypertension and stroke. We showed that a gene variant of CYP4F2 but not CYP4A11 was associated with increased 20-HETE excretio...

With global non-renewable resources and environmental issues becoming more apparent, the development of new energy vehicles have become the trend of auto industry. Hybrid vehicle becomes the key development of new energy vehicles with its long distance, low pollution, low fuel consumption characteristics and so on. The battery performances directly influence the quality of the whole vehicle per...

Drifting snow, the flow of dispersed snow particles near ground level under action wind, is a major form damage. When drifting occurs on railways, highways, and other transportation lines, it seriously affects their operational safety results in disasters. disasters frequently occur high latitudes northwest China. At present, most scholars are committed to studying prevention control measures b...

The state of charge (SOC) Lithium-ion battery is one the key parameters management system. In SOC estimation algorithm, Back Propagation (BP) neural network algorithm easy to converge local optimal solution, which leads problem low accuracy based on BP network. It proposed that Fireworks Elite Genetic Algorithm (FEG-BP) used optimize network, can not only solve traditional fall into maximum sol...
