Initially, the goal of Machine Learning (ML) advancements is faster computation time and lower resources, while curse dimensionality burdens both resource. This paper describes benefits Feature Selection Algorithms (FSA) for speech data under workload stress. FSA contributes to reducing dimension simultaneously retains information. We chose use robust Evolutionary Algorithm, Harmony Search, Pri...

friedel–crafts synthesis of triarylmethanes over 3-methyl-1-sulfonicacid imidazolium tetrachloroaluminate under green conditions:in this work, friedel–crafts (fc) alkylation of various arenes with aromatic aldehydes catalyzed by 3-methyl-1-sulfonic acid imidazoliumtetrachloroaluminate {[msim]alcl4}, as a green catalyst, to prepare triarylmethanes (tams) has been carried out. some aromatic aldeh...
