ESTIMATION OF BASIN-WIDE SNOW WATER EQUIVALENT USING LANDSAT-DERIVED SNOW LINE AND DEGREE-DAY METHOD
Rice (Oryza sativa L.) growth prediction is key for precise rice production. However, the traditional linear forecasting model ineffective under rapidly changing climate conditions. Here we show that rate (Gr) can be well-predicted by artificial intelligence (AI)-based neural networks (ANN) and gene-expression programming (GEP), with accumulated air temperatures based on degree day (GDD). In to...
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
