In order to improve the evaluation accuracy of political classroom teaching quality in universities, a DA-BP-based method universities is proposed. First all, constructing system university courses using framework behavior theory, consists 4 primary indicators and 15 secondary indicators. Second, university’s 2008–2013 annual assessment scores for were used as input data DA-BP network, 2013–201...

The method of improved wavelet transform neural network based on hybrid GA(genetic algorithm) is presented to diagnose rolling bearings faults in this paper. Genetic Artificial Neural Networks(GA-ANN) overcomes BP neural network’s fault of slow convergence, long hours of training, and falling into the local minimum point. And First, the signal is processed through the wavelet deoising, Then, th...

The visual aesthetics of villages are remarkably affected by the exterior quality traditional residences, influencing impression and assessment local culture. A proper scientific can protect cultures improve development villages. This research was conducted in a village consisting 115 residences (Mengjinglai village, which is on border between China Myanmar). backpropagation (BP) neural network...

Yield prediction for tomatoes in greenhouses is an important basis making production plans, and yield accuracy directly affects economic benefits. To improve the of tomato Chinese-style solar (CSGs), a wavelet neural network (WNN) model optimized by genetic algorithm (GA-WNN) applied. Eight variables are selected as input parameters output. The GA adopted to optimize initial weights, thresholds...

When applied to wire ice-covering forecasting, the back propagation (BP) neural network is a lack of guidance for selecting the neural network initial connection weight and network structure, which contributes to the problem of a high degree of randomness and poses a difficulty for selecting an initial node with global properties. Combination traditional forecasting methods of Mean Generating F...

suspended particles have deleterious effects on human health and one of the reasons why tehran is effected is its geographically location of air pollution. one of the most important ways to reduce air pollution is to predict the concentration of pollutants. this paper proposed a hybrid method to predict the air pollution in tehran based on particulate matter less than 10 microns (pm10), and the...

To ensure the safe and reliable operation of Li-ion battery energy storage systems, it is important to diagnose operational status aging degree batteries. In this study, an online fusion estimation method based on back propagation neural network genetic algorithm (BP-GA) used for estimating state charge (SoC) health (SoH) First, effective features SoC SoH batteries during charging discharging a...

Fatigue cracks often occur in the deck asphalt pavement of steel bridges at top longitudinal stiffening rib. To prevent this issue, traditional design strategy bridge structure was optimized, and a new approach is presented. This optimization technique exploits strength simulation steel—epoxy structure, stress concentration location subsequently determined. A solid model including sensitive are...

The aim of this study was to evaluate the correspondence of blood pressure (BP) measured using the direct intra-arterial method and indirect oscillometric monitor method. Twenty-three newborns with radial arterial catheters inserted were enrolled in this study. The gestational age (GA) ranged from 25-40 weeks and birth weight (BW) ranged from 700-3,550 g. Direct BP was measured using radial art...
