A series of experiments were conducted for Al-1.65%Si (mass fraction) alloy.melt to study.the formation of grain refining structure with ultrasonic stirring. the cooling curves of ingots with ultrasonic were measured and compared with those without ultrasonic. At the same time, the effect of the time of ultrasonic stirring on solidification structure of ingots was investigated. the influence of ultrasonic on the grain-refining efficiency.of ingots was analy.ed. In order to well understand the melts behavior under ultrasonic, by.using ammonium chloride solution, the simulation experiment was carried out and the temperature distribution in ingot with or without ultrasonic was compared. the results indicate that the ultrasonic reduces the temperature inhomogeneity.of melt, i.e. the ultrasonic helps to homogenize the melt temperature. the effect of stirring and heat generation in ingot start to occur with increasing the time of ultrasonic stirring.

Seasonal rainfall play. a vital role in both environmental dy.amics and decision-making for rainfed agriculture in Ethiopia, a country.often impacted by.extreme climate events such as drought and flooding. Predicting the onset of the rainy.season and providing localized rainfall forecasts for Ethiopia is challenging due to the changing spatiotemporal patterns and the country.s rugged topography. the Climate Hazards Group InfraRed Precipitation with Station Data (CHIRPS), ERA5-Land total precipitation and temperature data are used from 1981–2022 to predict spatial rainfall by.apply.ng an artificial neural network (ANN). the recurrent neural network (RNN) is a nonlinear autoregressive network with exogenous input (NARX), which includes feed-forward connections and multiple network lay.rs, employ.ng the Levenberg Marquait algorithm. this method is applied to downscale data from the European Centre for Medium-range Weather Forecasts fifth-generation seasonal forecast sy.tem (ECMWF-SEAS5) and the Euro-Mediterranean Centre for Climate Change (CMCC) to the specific locations of rainfall stations in Ethiopia for the period 1980–2020. Across the stations, the results of NARX exhibit strong associations and reduced errors. the statistical results indicate that, except for the southwestern Ethiopian highlands, the downscaled monthly.precipitation data exhibits high skill scores compared to the station records, demonstrating the effectiveness of the NARX approach for predicting local seasonal rainfall in Ethiopia’s complex terrain. In addition to this spatial ANN of the summer season precipitation, temperature, as well as the combination of these two variables, show promising results. © Institute of Atmospheric Phy.ics/Chinese Academy.of Sciences, and Science Press 2024.
