Artificial Intelligence (AI) is the human-like intelligence imbued in machines so that they can perform tasks normally require human intelligence. Machine learning an AI technique which carries on concepts of predictive analytics with one important distinction: system make assumptions, test hypotheses, and learn independently. XGBoost, Extreme gradient boosting, a popular machine-learning libra...

a one dimensional dynamic model for a riser reactor in a fluidized bed catalytic cracking unit (fccu) for gasoil feed has been developed in two distinct conditions, one for industrial fccu and another for fccu using various frequencies of microwave energy spaced at the height of the riser reactor (fccu-mw). in addition, in order to increase the accuracy of component and bulk diffusion, instanta...

Genomic Selection (GS) is a newly developed tool for the estimation of breeding values for quantitative traits through the use of dense markers covering the whole genome. For a successful application of GS, accuracy of the prediction of genomewide breeding value (GW-EBV) is a key issue to consider. Here we investigated the accuracy and possible bias of GW-EBV prediction, using real bovine SNP g...

Potassium is one of nutritional element that has an important effect on the quantity and quality of rice plant. Knowledge about the K critical level and plant response to different application rate of K, can effectively help with the proper use of this element. Therefore, in this study potassium (K) critical level for rice (Khazar variety) and prediction equation for grain yield were determined...

the identification of parental inbred lines to develop superior hybrids is a rather costly and time-consuming step in maize breeding. in some cases, pedigree information has been used to select diverse parental lines. in the case of iranian maize inbred lines, this information is not fully available. in this study we investigated the genetic distance (gd) based on simple sequence repeats (ssr) ...

Precision Agriculture applies state-of-the-art GPS technology in connection with site-specific, sensor-based crop management. It can also be described as a data-driven approach to agriculture, which is strongly connected with a number of data mining problems. One of those is also an inherently important task in agriculture: yield prediction. Given a yield prediction model, which of the predicto...
