Abstract: The output prediction of photovoltaic (PV) power station is necessary because the weather, environment and seasonal factors lead to the unstable PV power generation, which will affect the planning and scheduling of power system. Compared with the single model method, the linear combination method could improve the prediction accuracy of the output of PV power station. However, the linear combination forecast method is a simple convex combination of different prediction methods and is lack of general applicability. This paper presents a nonlinear combination method based on BP neural network and ARMA model to predict the output of PV power plant. This method based on the nonlinear relationship between the results of two single prediction models and the actual value, and utilize the nonlinear fitting ability of BP neural network, predicted the power generation capacity of PV power station. The nonlinear prediction theory and algorithm are given at the end of the article, and also compare nonlinear combined model with linear combined model of the power plant output prediction, the results show that the proposed method has a high accuration and an extensive applicability.

Abstract: Explosions of explosives can produce electromagnetic radiation signals. Based on the theory of the explosion of electromagnetic radiation, the effects of metal additives on the electromagnetic radiation produced by explosive detonation should be researched. In this paper, the electromagnetic radiation signal characteristic produced by the passivation RDX of metal additives explosion were studied by experimental. The rod-shaped antenna measurement system was used to measure the electromagnetic radiation signals generated by the different percentages of aluminum-containing passivation RDX and pure passivation RDX. The results show that the intensity of the electromagnetic radiation signal produced by the explosion is obviously increased by mixing aluminum. In the case of the same explosive mass, the signal intensity of the electromagnetic radiation generated by the explosion increases with the aluminum mass percentage is increased. When the content of aluminum is the same，with the increase of the mass of explosives，the intensity of the electromagnetic radiation signal generated by explosion also increases. The main component of the electromagnetic radiation signal frequency generated by explosives is less than 1MHz，the electromagnetic spectrum generated by explosives with the same composition is consistent.

Abstract: Purpose: MRI(Magnetic Resonance Imaging) estimates of brain iron deposition in thalassaemia patient using quantitative susceptibility mapping (QSM) and T2*-weighted methods. And to compare the two methods, if they have feasibility. Thirty-three thalassaemia patients underwent gradient echo sequence on the MR (Magnetic Resonance) scanner with whole-brain coverage to obtain the image data. Then to process the images and calculate the brain iron content using QSM (Quantitative Susceptibility Mapping) and T2*-weighted methods. Both images using QSM and T2* methods can clearly see the distribution of iron in the brain. But T2*-weighted method is less sensitivity for the detection of brain iron content, and only QSM method can quantify the iron content quickly and accurately. The tissue iron can affect the value of T2*, so T2*-weighted method can only detect the distribution of iron content. While the application of magnetic sensitive quantitative imaging can be very effective in routine non-invasive assessment of tissue components, especially iron, that is very important for the assessment of thalassemia patients.

Abstract: As known, naturally-occurring edible flora contained crucial compositions to human health (e.g., antioxidants). Prior studies revealed that decolorized metabolites (DM) of textile dyes might be used to enhance electron-transfer (ET) capabilities of dye decolorization and bioelectricity generation (DD&BG). Such ET stimulating phenomena were suspected to be associated with antioxidant characteristics. This study selected 6 edible flora to explore such relationship between antioxidant and dye-decolorizing characteristics. The finding indicated that DM of Gynura bicolor could show electron-shuttling capabilities to increase ET efficiency of DD&BG. Moreover, the dosage should exceed threshold level to trigger effective ET performance. Apparently, supplementation of sufficient DM of G. bicolor to azo dyes RBk5 significantly enhance efficiency of DD. Comparative assessment also suggested that chemical structure affected color removal efficiency, indicating optimal strategy for wastewater decolorization.
